Chapter 146

"It took me 10000 units of energy to ascend to the physical environment, and now there are 10780 units left."

Xu Ning then clicked after the cold and inflammation double source code.

——

Does it consume 23000 units of energy to improve the double source code of cold and inflammation?

whether

——

"Promotion to Tongyin environment only needs 23000 units of energy?"

Although 23000 units of energy is a lot, it is also less than Xu Ning's estimation.

The Tongyin environment is a watershed of the virtual environment. Xu Ning thought that this would have to be at least three times the energy consumption of the physical environment. Now it seems that it is only a little more than twice.

"There is only a difference of more than 10000 units of energy... If you get some opportunities again in this secret realm, you may be promoted to Tongyin realm before you get out of this secret realm!"

Xu Ning's eyes lit up.

In fact, if it were the same as before, Xu Ning would first use these energies to improve his secret skills.

After all, the secret skills consume less. The remaining 10780 units of energy is enough for Xu Ning to raise all the four secret skills one more level.

Only after seeing Chen Xiaoyi's strength, Xu Ning felt that it would be more cost-effective to accumulate these energy and promote Tongyin.

Thinking of this, Xu Ning closed the martial arts panel and continued to walk inside.

After taking a few more steps, Xu Ning was faced with another stone gate.

This stone gate looks much narrower and lighter than before.

Xu Ning pushed away again. There was a secret room of hundreds of square meters. After entering, there was a flame on the wall, which lit the secret room directly.

Xu Ning went in, looked around and found that two rows of neat monster skeletons were displayed in the secret room.

These skeletons are large and small, very complete, just like bone specimens.

After passing by each skeleton, Xu Ning can still feel the residual smell of terror from above.

"If these skeletons are taken out, their materials can certainly refine weapons with excellent finished products..."

Xu Ning continued to walk forward. At the back of the chamber was a stone platform.

Above the stone platform is a wooden frame, on which half of the white ribs are placed.

"This is..."

Xu Ning leaned over and looked at it carefully.

That half of the rib looks like an ordinary animal bone. Unlike other skeletons, there are still demon remnants.

But even so, Xu Ning knows that it must not be an ordinary product, otherwise it will not be placed in this position.

Xu Ning stretched out his finger and gently touched the half rib.

WOW!

At the moment when Xu Ning's fingertip touched the half rib, a silver and white fog light particle suddenly burst out on it and turned into a virtual shadow.

Between the virtual shadows, Xu Ning saw a vague monster figure, with a swollen head, a long mouth, twisting the space, swallowing everything around him.

The scene disappeared in a moment, but Xu Ning was shocked.

"This monster seems gray..."

Xu Ning's expression is complex.

The former white bone wilderness reminds Xu Ning of this secret place, which may be related to the great animal tide in Jifeng Prefecture 300 years ago.

The ghost of the monster just now is also very much like the legendary void beast and the rumored creator of the great beast tide.

"The void beast was killed by shifengxu 300 years ago... Is it gray and white that it will be the descendant of the void beast?"

Xu Ning recalled the scene of gray swallowing the belly of the monster.

This is very similar to the scene where the ghost of the monster devoured everything just now.

"When you get out of the secret place, you have to find gray."

Xu Ning thought to himself.

Then, Xu Ning carefully took the half rib in his hand, and the surface of the rib was cold.

Xu Ning stroked it gently.

"The material of this half rib is comparable to the strength of Taoist soldiers, but there is no power of Taoist soldiers..."

Xu Ning has checked Xie Wenyue's lightning bow before, so he also has a superficial understanding of Taoist soldiers.

Then, Xu Ning poured a wisp of true Qi into it tentatively.

Through Zhenqi, Xu Ning can understand its internal structure more clearly.

However, after a wisp of true Qi was poured into it, Xu Ning did not feel the obstruction of tight bones. On the contrary, Xu Ning felt an emptiness.

"This is..."

Xu Ning's eyes moved.

Xu Ning found that in this half of his ribs, an independent space was hidden!

That space is not big, only about ten cubic meters, but it is very real.

"This rib must be the rib of the empty beast, no doubt!"

Xu Ning is very confident about this.

The legendary void beast has mastered the terrible void talent.

"Maybe I can try to communicate the space in this rib..."

Xu Ning has realized that this half rib may be a treasure comparable to Taoist soldiers.

Xu Ning took out a pill at random from his waist, then clenched half of the white bone, urged his true Qi and moved his mind.

Then, the pill in Xu Ning's palm disappeared, but in the space in his ribs, there was an extra pill out of thin air.

"The space in this rib can communicate with the outside world and has the function of storing goods!"

Xu Ning smiled when the experiment was successful.

Xu Ning was still thinking about how to get rid of the Daoyin stone tablet at the door of the cave.

With this space, the problem is solved.

"I don't know if I can enter the living creature in this space..."

Xu Ning wants to activate his collaterals.

Ten cubic meters of space is enough for you to enter.

However, this kind of thing with unknown dangers, Xu Ning feels that he can't try it by himself.

But there are no living creatures in the environment right now

Suddenly, Xu Ning thought that there were thousands of insects in the buckle he wore around his waist.

After entering the secret place, Xu Ning almost forgot about the thousand source insects except facing the strong enemy and healing his wounds.

Today's Qianyuan insect can provide 150 units of energy per month. Its growth rate can't keep up with Xu Ning's demand.

Xu Ning opened the buckle on his belt.

At this time, there were nearly ten Reiki crystals in it.

Xu Ning absorbed it and obtained 90 units of energy.

Then Xu Ning pinched out the fat bug and put it in his hand.

"Try..."

Xu Ning urged Zhenqi and tried to send Qianyuan insect into the space in the ribs.

However, when Qianyuan insect was about to be sent into it, Xu Ning suddenly felt that the space in his ribs began to vibrate.

"It doesn't seem to work."

Xu Ning quickly stopped his action.

He had a feeling that if he put Qianyuan insect into it, the small space inside would collapse directly.

"Forget it."

Finally, Xu Ning gave up the idea for the time being.

If the space collapses due to the insertion of living creatures, the gain is not worth the loss.

"Pick some monster bones and take them out..."

After finding out how to use the rib space, Xu Ning took off part of the high-quality skeleton in the secret room and stuffed it into the rib space.

Take out these ribs and you can get a batch of pure source pills.

"Is this all the resources in the cave here..."

After selecting the high-quality skeleton, Xu Ning stuffed the rib into his chest and put it away.

He went around the secret room again and found no other resources.

"A Daoyin stone tablet, a hollow animal rib, plus more than 20000 units of energy, this harvest has been very rich..."

Xu Ning is going back the same way.

Click, click, click.

Just then, the stone platform where the empty beast's ribs were placed suddenly trembled slightly.

Then, the stone platform fell, and the secret room was on the ground. An underground entrance appeared, below which was a secret road.

"Go in and have a look..."

Since entering the cave, Xu Ning had only harvest and did not encounter danger, so he dared to go in and have a look when he saw the underground secret road.

Xu Ning went into the underground entrance, followed the secret stairs and continued down.

After walking for less than a minute, Xu Ning came to a smaller secret room.

In the secret room here, only two weak lights are burning, and the place is less than ten square meters.

In the corner of the chamber of secrets, there sat a human bone. A long crack opened at the cervical spine and sternum of the human bone.

Obviously, he was injured before he died.

"He should be the master of the cave and the master of the Taoist realm who left the treasures here."

Xu Ning has guessed.

He thought for a while, went to the white bone, knelt down and kowtowed three heads.

Many of the benefits I got in this cave were given by the Taoist master.

"If I guessed correctly, the Taoist master should have died in the tide of animals 300 years ago..."

At this time, Xu Ning has a new guess about the inheritance here and the whole secret territory: "this secret territory is likely to be an ancient battlefield during the beast tide. It has been transformed into a secret territory by a super strong man with terrible strength..."

"And this super strong man may be the former overlord of Jifeng state, Shifeng Xu..."

Xu Ning has heard the legend that when Shi fengxu killed the empty beast, he had several helpers.

This white bone may have been one of his helpers before he died, otherwise he could not have empty beast ribs.

As for the cause of his death, Xu Ning guessed that he might have suffered serious injury when killing the empty beast, and finally died.

So before he died, he hurriedly left the inheritance here on the ancient battlefield of the great beast tide.

"Thank you for your gift."

Xu Ning whispered and then stood up.

Click, click, click.

At the moment Xu Ning got up, a brittle sound suddenly came out on the wall.

On the wall, a stone brick fell, and a black metal arm guard appeared in the wall hole.

"This is..."

Xu Ning went to the front and took out the metal arm guard.

"It's a Taoist soldier!"

Xu Ning checked it and quickly came to the conclusion: "I just don't know what kind of attribute Taoist soldiers..."

Xu Ning inspired a wisp of true Qi and poured it into the metal arm guard.

Subsequently, complex and strange silver white lines appeared on the surface of the metal arm guard.

Then, Xu Ning felt that the air currents of water and fire in his body changed at the same time.

"This metal arm guard can actually trigger my dual attributes!"

Xu Ning's pupil contracted.

He suddenly realized that the metal arm guard was not only a Taoist soldier, but also a full attribute Taoist soldier!

While recuperating in the cave, Xu Ning and Xie Wenyue talked about Taoist soldiers.

Xie Wenyue told Xu Ning that according to the division of adaptive attributes, Taoist soldiers are divided into two types: ordinary Taoist soldiers and full attribute Taoist soldiers.

Ordinary Taoist soldiers can be refined by ordinary Taoist masters, but they can only be adapted to single genus. Even Taoist masters who practice the secret code of double genus can not refine double genus Taoist soldiers.

If you want to be both universal, you can only refine two kinds of Taoist soldiers.

In addition, another kind of all attribute Taoist soldiers is refined by higher-level Taoist masters.

The refining principle of this Taoist soldier is different from that of ordinary Taoist soldiers. It can adapt to all attributes and has countless inclusiveness.

The value of all attribute Taoist soldiers is unmatched by ordinary attribute Taoist soldiers.

"Thank you, master..."

Xu Ning clenched the black metal arm guard and bowed deeply to the white bone of the Taoist master again.

For a long time, Xu Ning straightened up again and walked out of the chamber of secrets.

Until this time, all the inheritance treasures in the secret territory here were taken by Xu Ning.

Xu Ning no longer stays and chooses the same way to return.

When he came to the entrance of the cave, Xu Ning took the stone tablet of Daoyin into the rib space.

At the same time, the black metal arm guard has also been carried on the forearm by Xu Ning.

After being re excited, the metal arm guard becomes extremely soft and close to the skin, just like the top soft silk attached to it.

"With this all attribute Taoist soldier, I am sure to defeat Chen Xiaoyi again!"

Now Xu Ning's mind of revenge is expanding.

Walking out of the cave, Xu Ning looked at the magma overflowing overhead and urged Yan Xi Sheng Gu Jing.

Wow.

Xu Ning's body appears translucent red armor.

"Look at the power of all attribute Taoist soldiers."

Xu Ning kept moving, and a faint silver light appeared on the surface of the black metal arm guard covered by his sleeves.

The translucent armor on Xu Ning's body suddenly condensed again, almost solid.

"This metal arm guard can greatly increase the effect of attribute properties!"

Xu Ning no longer hesitated. He moved and crossed the transparent diaphragm directly into the hot magma.

The magma was hot, but Xu Ning didn't receive any damage because he was covered with armor.

Xu Ning's body floated upward. After thirty breath, the whole person showed his body from under the magma.

He stepped on the surface of the magma and jumped straight back to the platform on the inner wall of the flame.

At this time, Xie Wenyue still didn't wake up after being knocked unconscious by the giant tiger monster.

The giant tiger monster lies on the ground with its wings folded.

Its head hung on the ground, and Xu Ning stood in front of its head, looking very small.

Xu Ning's shadow is reflected in the huge eyes of the giant tiger monster.

Seeing Xu Ning coming back, the giant tiger monster's eyes showed a look of satisfaction.

"Thank you."

Xu Ning also nodded and thanked the giant tiger monster.

If the giant tiger monster hadn't brought him here, he wouldn't have such an opportunity.

Hoo Hoo.

Seeing that Xu Ning came out unharmed, the giant tiger monster stood up and flapped his wings.

After staring at Xu Ning for the last time, the giant tiger monster didn't turn back and flew out of the flame hole.

The huge wind flapping its wings made the magma under it surge again.

"I'm leaving now?"

Xu Ning looked at the giant tiger monster that disappeared in the field of vision and shook his head gently.

The giant tiger monster seems to have completed a certain task and then left.

Xu Ning gave a low sigh.

"Shifengxu, void beast, gray, giant tiger monster, Taoist Master inheritance... What kind of connection does all this have..."
