"Seed pack? It seems to be a high-tech version, it's not bad!"

In the dark storage space, a fertilizer bag suddenly appeared about 50kg of seeds, which was quite expensive!

Take out the seeds, and the properties of the game panel pop up naturally:

["Strong Disaster Resistance" Edition Wheat Seeds]

【Description】: After being trained by senior planters carrying natural energy, they have a certain strong ability to resist cold, heat, pests, and....

[Performance]: 1050 jin per mu yield

"Oh, it's really good. With such strong disaster resistance, you can still get a yield of over 1,000 kilograms per mu, which is very good!"

Seeing that the attributes were so powerful, Sumo quickly put the wheat seeds back to avoid unnecessary damage.

For 50kg of seeds, it is impossible to plant about one and a half acres of seeds according to the amount of seeds required per mu.

Then you can produce 1,400 kilograms!

It can be crushed into flour by stone milling, at least eight or nine hundred kilograms, which is enough for one person to eat for about a year!

After lying in the sun for a while, Sumo got up and returned to the "skylight" of the shelter.

"Then the remaining tasks are just about filling in this big ceiling hole!"

The place where the dog-headed man was continuously blasted with a fireball was still standing on the outside.

He took out a unit of stone and another unit of iron. Seeing that the survival point had dropped to 25 points, Sumo simply threw himself into the survival point and repaired it all.

The stone and iron on the ground turned into flowing water and attached to the entrance of the big cave.

Slowly, the steel bars began to extend, cement concrete appeared out of thin air, and the large holes that were opened began to heal and gradually became intact.

"It's a pity that Magu doesn't have much material and the thickness of the stone slabs is not good, which is far inferior to my stone shelter. However, it is not realistic to build such heavy and thick stones with human power!"

With a smile, Sumo came to the oil well and began to check the harvest that had been working for almost half a day.

At this time, the diesel had accumulated to about 6.5L, and in the square storage space, it seemed to have become solid and remained motionless.

The toluene collected in another box was about 500g at this time, as a colorless clear liquid. After thinking about it, Sumo simply took out the mineral water bottle that had not been mentioned before and put the toluene into the mineral water bottle.

This toluene is enough to make some picy sour. As for the subsequent production of explosive packs in large quantities, it still has to be collected slowly.

However, Sumo was going to take out the previous empty oil barrel and throw it into the oil barrel.

The diesel of Bongbeng is no longer enough, and these diesels are just added.

Walking out of the shelter gate, Oreo was still sleepy on the ground.

Shaking his head, Sumo was about to go around to cheer for Bengbeng, and his expression quickly became serious.

"Oreo is up and working!" Oreo, who was still lying on the ground, was also startled and rushed up. After seeing the distance, he couldn't help but bark a few times.

In Sumo's vision, a black fog that seemed to be connected to the sky suddenly appeared in the distance where the sun was shining brightly!

The black fog enveloped a piece of land, as if there were evil ghosts, and it seemed like a disaster of destruction.

Compared to the last fog, this time the fog seemed to be mixed with malicious intentions, the color was darker and more terrifying!

If calculated based on distance, it is exactly less than one kilometer north of the underground shelter.

Sumo is no stranger to mist.

The ruins that I entered for the first time were entered through the fog.

"The ruins suddenly appeared at this time. There is no pattern of appearance at present!" Sumo thought about it in his mind, and went to the gate of the shelter and pulled the hinge plate and closed the door!

After pushing the hinge plate back inside, press all the lids on the cover in turn, and Sumo quickly walked towards the jumping place.

There are good things in the ruins!

And it is a finished product, the kind that can be converted into productivity or combat power as soon as it is taken out.

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

But at the same time, there are many dangers in the misty ruins!

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

It seems that there is an independent law that acts in the fog ruins, and even advanced things like the system will treat the things in the fog ruins as ordinary items.

Only after taking it out of the outside world can you see the special functions of the item.

As for the question of whether to go or not, Sumo didn't even think about it.

Dangers and harvest coexist in the ruins, but compared to harvest, these dangers are nothing.

not to mention...

After looking at the water bottle with toluene lying in the storage space, Somo was confident.

At this time, Oreo had already sat in his position first, holding the safety belt with his mouth and buckled it himself.

As Sumo put on his helmet and tied up his seat belt, he rumbling and burst out with strong power and left.

From the overlooking view of the wilderness, Somo was like a fearless warrior, driving his vehicle and rushing forward into the black fog.

Three kilometers...

Two kilometers...

One kilometer...

Until only 400m away from the ruins, Sumo stopped the car and tried his best to look at the scene in the fog.

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

After driving around the ruins for a while, Sumo decisively returned to the base.

He parked Bengbeng into the garage, came to the front door, quickly moved the roulette lock, and with a slam, the lock tongue was retracted.

Putting Oreo in, closing the door, Somo quickly walked to the energy room and switched the energy supply from the battery to the diesel engine.

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

While under the self-test, Somo took all the ingredients to prepare picric acid.

To make picric acid, phenol disulfonic acid is essential.

Therefore, the key is to make phenol from toluene.

It is only necessary to react with toluene and sulfuric acid to form p-methylbenzenesulfonic acid. p-methylbenzenesulfonic acid reacts with sodium sulfite to form sodium p-methylbenzenesulfonic acid.

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

Sodium hydroxide can be solved by electrolyzed saline, and sodium sulfite can be prepared with sulfur, so there is no difficulty in the process.

With Somo's high school experiment level, a series of actions were quickly completed, and a small amount of sulfuric acid and phenol were obtained.

Put the prepared phenol aside, somo continued to make a lot of sulfuric acid and nitric acid.

After preparing some sulfuric acid and passing phenol into it, phenol disulfonic acid can be easily obtained.

After taking nitric acid sacredly, phenol disulfonic acid nitrocresol, the famous "picric acid" is released!

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

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

The chorionic and sour taste in front of me is so powerful that it is so powerful!

The power of black gunpowder is only one-tenth of nitric acid, and the power of nitric acid is only one-tenth of picric acid. That is to say, 1 kilogram of picric acid is equivalent to 10 kilogram of ammonia nitrate and also 100 kilogram of black gunpowder!

Pyric acid is even more powerful than TNT. In modern explosives, the intensity of civilian TNT explosives is between 8 and 13, and picric acid is about 116!

Although this is just a comparison of "severeness", the power of fierce explosives is definitely not comparable to black gunpowder!

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

In fact, the C4 explosives used by special forces in the 21st century are not much more powerful than picy and sour!

Carefully put all the picy acid in a small wooden cup and place it in a difficult place to reach, Sumo took out the iron block and started the last step of making:

A crossbow that holds picy sour!

If you want to fight with monsters that can move with broken spines in the ruins, it is useless to simply use crossbow arrows. Even if you stab the head, such beasts can continue to attack without fear of death.

But if you fill the picric acid in the arrow, it only takes a few dozen grams, and after being rubbed, vibrated, or impacted, it will burst out with terrifying power!

Not to mention monsters, even the iron sheet can be blown away and blown away!

He took out a large cup of Youneng water and drank it. He brought the robot arm and Sumo began to make crossbow arrows quickly.

For close combat, crossbow arrows do not need to be polished carefully. As long as they can maintain stable launch within 20m, they are excellent products.

After another half an hour, Somo completed the preparation of 10 crossbow arrows.
Chapter completed!
