My Post-Apocalyptic Shelter Levels Up Infinitely!

“A seed pack? It seems to be an advanced version, not bad!”

In the dark storage space, a fertilizer bag containing about 25kg of seeds suddenly appeared, the quantity was huge!

Su Mo took out the seed, and the properties of the game panel naturally popped out:

[“Strong Anti-Disaster” Version of Wheat Seeds]

[Description]: Cultivated by distinguished planters who carry natural strengths, these seeds have strong abilities to withstand disasters. They possess a certain degree of resistance to cold, heat, pests, and others.

[Yield]: 1050 catties per mu

“Hey, it’s quite good. With such strong resistance to disasters, and yields more than 1000 catties per mu, not bad at all!”

Seeing that the properties were so strong, Su Mo quickly put the wheat seeds back to avoid unnecessary damage.

25kg of seeds, if calculated according to the amount of sowing per mu, approximately one and a half mu of wheat could be planted.

When the time comes, 1400 catties of wheat could be grown!

If stone-milled to be made into flour, there would be at least eight or nine hundred catties of flour, which is enough to feed a person for about a year!

After lying in the sun for a while, Su Mo got up and returned to the “skylight” in the shelter.

“Now the remaining task is to fill in this big hole in the ceiling!”

There were steel bars still erected outside the spot where the kobold had fixedly and continuously attacked using firebolts.

Su Mo took out a unit of stone and a unit of iron. Seeing that his survival points had dropped to 25 points, Su Mo frankly invested the survival points to repair the hole completely.

The stone and iron on the ground had turned into liquid and they were attached to the big hole.

Slowly, the steel bars began to stretch, cement concrete appeared out of thin air. The large hole began to patch up and gradually became intact.

“Too bad the materials that Magoo owned weren’t much, and the thickness of his slates are not ideal. Too far behind compared to my shelter made of stone. But it would be unrealistic to construct thick and heavy stones like that with just manpower anyway!”

With a chuckle, Su Mo came to the motor-pumped oil well and began to check his gains after a short period of work.

At this time, the diesel fuel had accumulated to about 6.5L. In the square storage space, it seemed as if it had become solid and motionless.

The toluene collected in the other box was about 500g at this moment. It was a colorless, clear liquid. After pondering, Su Mo took out the mineral water bottle from before and transferred the toluene into the bottle.

This amount of toluene was sufficient to make some picric acid. As for the subsequent plan of mass-producing explosive packs, the amount has to be collected slowly.

As for the diesel fuels, Su Mo planned to take out an empty oil barrel from before and transfer them into the barrel.

The buggy’s diesel was not enough anymore, the amount of diesel collected was just right for a refill.

Walking out of the shelter gate, Su Mo noticed that Oreo was still lying on the ground napping.

Shaking his head, Su Mo was prepared to go past Oreo to give the buggy a refill. However, when he incidentally turned his head, his expression immediately became serious.

“Oreo, time to get up for work!” Oreo, who was still lying on the ground was startled as well, she got up immediately. Detecting what was in the far distance, she could not help barking a few times.

In Su Mo’s field of vision, the originally bright sun that shone in the distance has now been covered by murky dark fog!

The fog-shrouded a piece of land, as if evil spirits were emerging, like a devastating disaster.

Compared to the fog last time, this time the fog seemed to be fused with malice, the color was deeper, and it looked scarier!

To calculate by distance, it happened to be less than one kilometer north of the underground shelter.

Fogs were not unfamiliar to Su Mo.

The ruin he had entered for the first time was through a fog.

“The ruin suddenly appeared at this time, and there is no regular pattern of its appearance at all!” While he was contemplating it, Su Mo came to the front door of the shelter and swiftly pulled the hinge plate to close the door!

After pushing the hinged plate back into it, pressing and closing all the lids in turn, Sumo walked quickly to the buggy.

There were valuables in the ruin!

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

Compared to the underground ruins of “Magoo”, there were obviously more valuable things in the fog ruin.

However, there would be countless dangers in the fog ruin at the same time!

After entering the fog, all the functions of the game panel and the system will be temporarily disabled, losing effectiveness.

There seems to be an independent rule acting in the fog ruin, and even advanced things like the system will be treated as ordinary items in the fog ruin.

The special functions of an item can only be seen after it is taken out to the outside world.

As for the question of whether or not to go, Su Mo did not even think about it.

Danger and rewards coexist in ruins, but compared to rewards, these dangers are nothing at all.

Not to mention…

Looking at the water bottle filled with toluene lying in the storage space, Su Mo’s confidence grew high.

Oreo was already sitting in her seat by this time, she had buckled the seat belt with her mouth.

Su Mo put on his helmet and fastened his seat belt as well. With a loud bang, the buggy zoomed off with powerful momentum.

Looking from a bird’s eye view of the wilderness, Su Mo was like a fearless warrior, driving the vehicle and charging into the black fog.

Three kilometers…

Two kilometers…

One kilometer…

When the ruins were only 400m away, Su Mo stopped the car and fixed his gaze to look at the scene in the fog.

Unfortunately, just like the last time, the fog was thick and dark. Standing outside of the fog, Su Mo could not see what was inside.

He drove the car around the ruins for a while and found that there was no end in sight. Su Mo decisively returned to the base.

After parking the buggy into the garage, he came to the front door and swiftly flipped the large lock of the roulette. The bolt locked with a click.

After letting Oreo in, Su Mo closed the door and walked quickly to the energy room, and switched the energy supply from the battery to the diesel generator.

He then moved toward the workbench and turned on the self-check switch.

While self-checking, Su Mo took all the raw materials for the preparation of picric acid.

To produce picric acid, phenol disulfonic acid is essential.

Therefore, the use of toluene to make phenol is the key.

Based on the level of Su Mo’s lab experiments in high school, he completed a series of steps and obtained a small amount of sulfuric acid and phenol in a short period.

Putting the prepared phenol aside, Su Mo continued to make a large amount of sulfuric acid and nitric acid.

After preparing more sulfuric acid, the phenol was added. The phenol disulfonic acid was easily created.

Su Mo sacredly brought over the nitric acid, treated the phenol disulfonic acid, and then the trinitrocresol, The famous “picric acid” was then produced!

Looking at the bright yellowish powder in front of him, Su Mo rolled his slightly sore shoulders.

The preparation of this set was extremely simple. Combined with the efficiency and focus benefitted by the workbench, Su Mo had completed the production in roughly less than two hours.

The picric acid that looks plain and ordinary could cause a terrifying impact!

The power of black gunpowder was only one-tenth of nitrate-ammonia explosives, and nitrate-ammonia explosives are only one-tenth that of picric acid. This means that 1 catty of picric acid is equivalent to 10 catties of ammonium nitrate and 100 catties of black gunpowder!

Picric acid is more powerful than TNT. In modern explosives, the strength of civilian TNT explosives is between 8-13, and picric acid is around 116!

Although this was just a comparison of “magnitude”, the power of explosives is not comparable to that of black gunpowder!

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

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

After carefully filling all the picric acid in a small wooden cup, Su Mo placed it in an area that was not easily accessible. He then took out an iron block and began to proceed to the final step:

Crossbow arrows that contained picric acid!

If he were to fight the monsters that can move with broken spines in the ruins, using a simple arrow will be of no use. Even if it was hit on its head, this kind of beast can continue to attack without any fear of death.

But if the arrow is filled with picric acid, merely tens of grams of it will explode with terrifying power after being rubbed, shaken, or hit!

Even an iron skin can be blasted and destroyed, let alone a monster!

Su Mo took out a large glass of psychic energy water and drank it. Then he put on his mechanical arm and quickly began to make crossbow arrows.

Used for close combat, the crossbow arrows do not need to be carefully polished. As long as it can be fired stably within 20m, it was an excellent product.

After another half an hour, Su Mo completed the preparation of 10 crossbow arrows.

He carefully filled the grooves of the arrows with picric acid, then glued them with tape and small pieces cut from plastic bottles. The explosive crossbow arrows were complete!
