Chapter 272

There is metal in the black zircon, and it is extremely hard. Even if he uses his Yanyang finger to touch it, and it wastes a lot of real energy, it can only explode a few feet square, but cannot explode the whole piece of black zircon.

Lu Chen released his soul power to investigate the situation around the cellar.

It was found that the black zircon layers above and below the cellar were very thick, several miles long, and thousands of feet thick in the front and rear directions.

The left side is the weakest, the black zircon layer is only ten feet thick, but that is the exit, and there are countless guards waiting to kill him.

The only thing that can use their brains is the right side. The black zircon layer over there is about 500 feet. If they have enough strength, they may be able to create a way out.

Lu Chen sacrificed Zhantian and slashed at the right wall.

The power of Zhantian is so powerful, but it is far from enough to cut through the black zircon layer that is one foot square.

To break through the entire black zircon layer on the right, at least five hundred knives would be required!

Five hundred knives can be cut, but the problem is that after the cut, most of Lu Chen's stamina and true energy have been consumed, and he needs to recover before he can cut again.

Lingshen Yuanye and Sanwen Lingqi Dan are limited, let alone five hundred knives, not even fifty knives.

The only way now is to break through the fourth level of Yuandan Realm!

The basic strength of the third level of Yuandan Realm is not enough, only 30 million catties.

And the basic strength of the fourth level of Yuandan Realm is 60 million catties!

The basic strength has been fully doubled, and the power to cut the sky has been improved even more.

If you practice the second sword of Zhantian, it will be more powerful and powerful than the first sword.

Lu Chen looked at the Chaos Orb, and saw that the vein core was gradually moving towards the new spiritual energy channel with the little remaining aura. It seemed that he wanted to take possession of this new aura.

Lu Chen stretched out his hand, reached into the chaotic bead, helped the vein core, and pushed it to the edge of the new spiritual energy vein.

In the blink of an eye, the vein nucleus carried the original aura and merged into the new aura.

It didn't take long for the pulse nucleus to send news to Lu Chen that it had already occupied the new spiritual energy vein, and Lu Chen could enjoy it at any time.

Lu Chen grabbed out this new spiritual energy vein, then sat down cross-legged, and operated the Nine Dragons to return to one match, frantically extracting the rich spiritual energy from the new spiritual energy vein.

The reason why Lu Chen took out the spiritual energy veins instead of letting the Yanlong veins into the Chaos Orb to draw it was because the two dragon veins worked together, which was much faster and more efficient than one dragon vein.

Now the danger Lu Chen faces is, will the Lord of the Demon City come back before he breaks through?

The city lord of the demon city is a powerful man in the Tiangang realm, and he is also the strongest demon in the demon city. If the lord of the demon city comes back in time, it will be a big deal. Lu Chen is no match for the city lord of the demon city no matter what.

An hour passed, only the guards outside the door were shouting and cursing, and the Lord of the Demon City hadn't returned yet.

And the large amount of spiritual energy extracted by the double dragon veins was all transformed into strands of true energy, enriching the Chaos Orb.

It has to be said that this larger spiritual energy vein contains a lot of spiritual energy and is also very pure, allowing Lu Chen to obtain faster and more true energy.

Another six hours passed, and the black iron gate still hadn't been opened, and the Lord of the Demon City still hadn't come back.

However, that new spiritual energy channel has been sucked thin a little, and the chaotic orb has already been filled with real energy and compressed to the limit.

Boom!

There was a bang in the Chaos Orb.

The zhenyuan, which had been compressed to the extreme, bounced back and stretched the Chaos Orb in an instant, fully doubling in size, making the space of the Chaos Orb reach six hundred feet square.

The chaotic orb replaced the dantian, so Lu Chen broke through and crossed a huge gap.

The fourth level of Yuan Dan Realm!

Lu Chen did not stop, and continued to draw the spiritual energy from the spiritual energy vein to consolidate the new realm.

After another hour, Lu Chen's violent breath gradually calmed down, and his realm finally consolidated.

Only then did Lu Chen stop his work, withdraw his spiritual energy, took out the Xiaguang knife, and prepared to try the knife.

With his current strength, with the increase of the double dragon veins, his own strength is as high as 180 million catties.

The first knife to cut the sky can be used at any time, and its power is at its maximum.

With a single slash, the black zircon layer was cut three feet apart on the spot. Sure enough, after breaking through to the fourth level of the Yuandan realm, Zhantian's power was much stronger.

After one cut, the physical energy and real energy are not consumed much, and there is still energy left!

Lu Chen continued to slash, with multiple slashes in a row, until his stamina and true energy were exhausted.

After drinking a drop of spirit spirit essence liquid and taking thousands of three-pattern spirit energy pills, he recovered.

And the black zircon layer was only cut out less than 20 feet, and it was still far away from 500 feet.

Limited to the support of Lingshen Yuanye and Sanwen Lingqi Pill, there is no way out for the first cut to cut the sky.

Lu Chen collected his mind, silently recited the mantra of the second sword of Zhantian, and slowly operated the mental method of the second sword of Zhantian, so that the true energy of the Chaos Orb quickly walked once according to the specific route of the second sword of Zhantian, and finally poured into the blade.

"Zhantian, the second knife!"

With one slash, the space was shattered, and the power of the knife rolled up a torrential wave, impacting the entire cellar.

All the sun bugs were instantly killed by the blast, and the walls of the cellar were also shaken by the blast, causing the pavilion on the top to sway, and even affecting the entire City Lord's Mansion.

boom!

The blade slashed and the ground shook.

The power of the blade was so strong that it directly smashed the black zircon layer by hundreds of feet!

Zhan Tian's second cut was so powerful that it was beyond imagination, but it emptied all of Lu Chen's physical energy and true essence.

Lu Chen stood standing with the sword, his face was pale, and his body was on the verge of falling, as if he had returned to the situation when he sacrificed the first sword to cut the sky when his realm was low.

Zhantian, it is really...

It's so awesome!

After drinking the Spiritual Essence Liquid and taking the Sanwen Spiritual Qi Pill, Lu Chen quickly recovered, and then...

Keep chopping!

After chopping five times in a row, the black zircon layer on the right side was completely broken through, and mud and soil were finally seen.

With the power of cutting the sky, Lu Chen forcibly cut a way out!

The earth-type rune chain with the profound meaning of escaping from the ground landed on him, and Lu Chen could walk away from the ground and walk away.

However, in the exploding black zircon layer, after walking about three hundred feet, Lu Chen found a three-foot-square cave.

This cave is completely covered by the black zircon layer, because Lu Chen's attack on this side happened to shake out the cave, otherwise no one would know that there is such a cave in the black zircon layer.

This cave is very unusual, there is a terrifying Qi machine flowing out, blocking any exploration of soul power.

There is someone in the hole!

Moreover, he is still a person with extremely terrifying cultivation base!

Lu Chen thought for a moment, and walked in decisively. If he didn't go in and take a look, how would he know what was inside?

This cave is buried deep in this black zircon layer and will never see the light of day. Even if there were people, they would have died long ago.

In case, what treasures are left behind by the dead?

Then send it!

If you don't go deep into the tiger's lair, how can you get a tiger cub?

As soon as he entered the cave, the terrifying aura became even more intense, making Lu Chen unable to breathe. Even if he released the majestic soul power, he could only resist half of the pressure of the aura, and Lu Chen was still responsible for the other half.

In addition to the aura, there was also a simple and desolate aura rushing towards his face, as if telling Lu Chen that he had been silent for millions of years.
