Chapter 81

"Seed bag? It seems to be a high-tech version, good!"

In the dark storage space, about a fertilizer bag with about 50kg seeds suddenly appeared, and the quantity was not poor!

Take out the seed, and the attributes of the game panel will pop up naturally:

["strong disaster resistance" version of wheat seeds]

[description]: trained by senior planters who carry natural energy, they have certain resistance to cold, heat, insects and And strong disaster resistance.

[output]: 1050 Jin per mu

"Ah, it's really good. It's very good to have such a strong anti disaster ability and a yield of more than 1000 Jin per mu!"

Seeing that the attribute was so powerful, sumo quickly put back the wheat seeds to avoid unnecessary damage.

50kg seeds, according to the number of seeds needed per mu, can be planted about one and a half mu.

At that time, 1400 Jin will be produced!

The flour ground by stone mill is at least eight or nine hundred jin, which is enough for a person to eat for about a year!

Lying in the sun for a while, sumo got up and returned to the "skylight" of the shelter.

"Then the only remaining task is to fill the big hole in the ceiling!"

At the place that was blasted away by the dog headed man with a fireball, there are still steel bars standing outside at this time.

He took out a unit of stone and another unit of iron. Seeing that the survival point had been reduced to 25 points, sumo simply invested directly in the survival point and repaired it all.

The stones and iron on the ground became flowing water and attached to the big hole.

Slowly, the reinforcement began to extend, the cement concrete appeared out of thin air, and the open hole began to heal and gradually became intact.

"Unfortunately, Magu doesn't have many materials, and the thickness of the stone slab is not good, which is far from my stone refuge, but it's unrealistic to build such heavy and thick stones by manpower!"

With a smile, Su Mo came to the oil well and began to check the harvest of nearly half a day's work.

At this time, the diesel oil has accumulated to about 6.5l, and in the square storage space, it seems to become a solid, motionless.

At this time, about 500g of toluene was collected in another box. As a colorless clear liquid, Su Mo simply took out the previous mineral water bottle and put toluene into the mineral water bottle.

So much toluene is enough to make some picric acid. As for the subsequent mass production of explosives, we still have to collect them slowly.

Instead, Su Mo is going to take out the previous empty oil barrel and pour it all into the oil barrel.

The bouncing diesel oil is not enough, and it is just added.

Out of the gate of the shelter, Orio was still lying on the ground sleepy.

Shaking his head, Su Mo was about to bypass the top to refuel bouncing, inadvertently turned his head, and his expression quickly became serious.

"Oreo, get up and work!" Oreo, who was still lying on the ground, was also startled and rushed up. When he saw the distance, he couldn't help but bark a few times.

In Su Mo's vision, the sun was shining in the distance, but suddenly there was a black fog like the sky!

The black fog shrouded the land, as if there were evil spirits, but also as if it was a disaster of destruction.

Compared with the previous fog, this time the fog seemed to be mixed with malice. The color was darker and looked more terrifying!

If calculated according to the distance, it happens to be less than a kilometer north of the underground shelter.

Su Mo is no stranger to fog.

It was through the fog that the ruins that I entered for the first time.

"The ruins unexpectedly appeared suddenly at this time. At present, there is no law of occurrence!" Su Mo thought while coming to the gate of the refuge and pulled the hinge plate directly to close the gate!

Push the hinge plate back inside, press all the covers in turn, and Sumo quickly walked to the jumping place.

There are good things in the ruins!

Moreover, it is a finished product, which can be converted into productivity or combat effectiveness as soon as it is taken out.

Compared with the underground relics of "Magu", there are obviously more good things in the fog relics.

But at the same time, the fog remains dangerous!

After entering, the functions of the game panel and the system will be temporarily blocked and lose their effectiveness.

It seems that there is an independent law acting on the fog relics, and even the system, a high-level thing, will treat the things in the fog relics as ordinary objects.

Only after taking it out of the outside world can we see the special functions of the object.

As for whether to go, sumo didn't even think about it.

Danger and harvest coexist in the ruins, but compared with harvest, these dangers are nothing at all

What's more?

Looking at the water bottle with toluene lying in the storage space, sumo's confidence was high.

At this time, Oreo had already sat in his position one step first, holding the seat belt in his mouth and fastening it by himself.

As Su Mo put on his helmet, tied his seat belt, and with a bang, he bounced out of strong power and left.

From the overlooking perspective of the field, Su Mo was like a fearless warrior, driving the vehicle and rushing forward into the black fog.

Three kilometers

Two kilometers

One kilometer

Until only 400m away from the ruins, sumo stopped his car and tried to look into the fog.

Unfortunately, just like last time, the fog was dark and thick. Standing outside, I couldn't see what was inside.

Driving around the ruins for a while, Su Mo resolutely returned to the base after finding that he couldn't see the end.

Will jump into the garage, come to the front door, quickly toggle the wheel lock, with a click, the lock tongue income.

After letting Oreo in and closing the door, sumo hurried to the energy room to switch the energy supply from the battery to the diesel engine.

Come to the workbench and turn on the self-test switch.

During the self inspection, sumo took all the raw materials for preparing picric acid.

To make picric acid, phenol disulfonic acid is essential.

Therefore, the key is to produce phenol from toluene.

It only needs to react with toluene and sulfuric acid to produce p-methylbenzenesulfonic acid. P-methylbenzenesulfonic acid reacts with sodium sulfite to produce sodium p-methylbenzenesulfonate.

Sodium sulfonate reacts with sodium hydroxide to produce sodium p-methylphenol, and sodium cresol reacts with SO2 to produce phenol.

Sodium hydroxide can be solved by electrolysis of salt water, and sodium sulfite can be prepared by sulfur, so there is no difficulty in the process.

Taking sumo's high school experimental level, he quickly completed a series of actions and obtained a small amount of sulfuric acid and phenol.

Put the prepared phenol aside, and Sumo continues to produce a large amount of sulfuric acid and nitric acid.

When some sulfuric acid is prepared and phenol is introduced, phenol disulfonic acid is easily obtained.

The sacred took nitric acid and nitrated phenol disulfonic acid, and trinitrocresol, also known as "picric acid", came out!

Looking at the bright yellow powder in front of him, sumo shook his slightly sour shoulder.

The preparation of this set is extremely simple, with the efficiency and focus bonus of the workbench. It is estimated that sumo completed the production in less than two hours.

Picric acid, which looks ordinary in front of you, is terrifying with its high power!

The power of black powder is only one tenth of that of nitramine explosive, and the power of nitramine explosive is only one tenth of that of picric acid, that is to say, one kilogram of picric acid is equivalent to 10 kilograms of ammonia nitrate, and also equivalent to 100 kilograms of black powder!

Picric acid is even more powerful than TNT. Among modern explosives, the intensity of civil TNT explosives is between 8-13, and picric acid is about 116!

Although this is only a comparison of "ferocity", the power of dynamite is definitely not comparable to black powder!

Even if there is no power of 100 times, there is still power of 80-90 times.

In fact, C4 explosive used by special forces in the 21st century is not much more powerful than picric acid!

Carefully put all the picric acid in a small wooden cup and put it in a place that is not easy to touch. Su Mo took out the iron block and began the final step of making:

Contain the crossbow of picric acid!

If you want to go to the ruins and fight with those monsters who can still move after breaking their spines, it's useless to simply use crossbows and arrows. Even if you pierce your head, this beast can continue to attack fiercely and fearlessly.

But if you fill the arrow with picric acid, it only takes a few tens of grams. After being rubbed, vibrated and impacted, it will burst out with terrifying power!

Don't say it's a monster, even the iron sheet can be blasted away, blasted!

Take out a large cup of Youneng water and gulp it. Take the mechanical arm, and Su Mo starts to make crossbows quickly.

As used in close combat, the crossbow does not need to be polished carefully. As long as it can be fired stably within 20m, it is an excellent product.

In another half an hour, sumo completed the preparation of 10 crossbows and arrows.

Take picric acid, carefully fill it into the groove of the arrow, and then stick it with adhesive tape and small pieces cut from plastic bottles. The explosion of the crossbow is complete!
