My Post-Apocalyptic Shelter Levels Up Infinitely!

　　 "The seed pack? It seems to be a high-tech version, not bad!"

　　In the dark storage space, suddenly there was about a fertilizer bag with about 50kg of seeds, which is a lot of money!

　　 took out the seed, the attributes of the game panel naturally popped out:

　　【"Strong Anti-disaster" version of wheat seeds】

　　 [Description]: After being trained by senior growers who carry natural energy, they have a certain degree of resistance to cold, heat, pests, and other strong disaster resistance.

　　 [Yield]: 1050 catties per mu

　　 "Hey, it's great, with such a strong ability to resist disasters, and with a yield of 1,000 kilograms per mu, it's very good!"

　　 Seeing that the attributes are so strong, Somo hurriedly put the wheat seeds back in order to avoid unnecessary damage.

　　 50kg of seeds, calculated according to the number of sowing required per acre of land, about one and a half acres can be planted.

　　 will be able to produce 1,400 catties by then!

　　 is milled into flour by stone milling, which is at least eight or nine hundred catties, which is enough for one person to eat for about a year!

　　 Lie in the sun for a while, Sumo got up and returned to the "skylight" of the refuge.

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

　　 The place where the kobolds used fireballs to blast them continuously at fixed points. At this time, there are still steel bars standing outside.

　　 took out a unit of stone and another unit of iron. Seeing that the survival point had dropped to 25 points, Somo directly invested in the survival point and repaired them all.

　　 The stones and iron on the ground turned into running water and attached to the big hole.

　　Slowly, the steel bars began to stretch, the cement concrete appeared out of thin air, and the large open holes began to heal and gradually became intact.

　　 "Unfortunately, there are not many materials in Magu, and the thickness of the slate is not good enough. Compared with my stone refuge, it is far behind, but such a heavy and thick stone is unrealistic to build with manpower!"

　　 With a smile, Somo came to the oil well and began to check the harvest after a short period of work.

　　At this time, the diesel oil has accumulated to about 6.5L. In the square storage space, it seems to have become solid and motionless.

　　 The toluene collected in the other box was about 500g at this time. It was a colorless, clear liquid. After thinking about it, Somo simply took out the mineral water bottle and put the toluene into the mineral water bottle.

　　 Such toluene is enough to make some picric acid. As for the subsequent mass production of explosive packs, it still has to be collected slowly.

　　 It's the diesel fuel. Somo is going to take out the empty oil drums and put them all into the oil drums.

　　 The bouncing diesel is not enough, and the diesel is just added in.

　　 walked out of the refuge gate, Oreo was still lying on the ground sleepy.

　　 shook his head. When Somo was about to go around to cheer on Beng Beng, he inadvertently turned his head and his expression quickly became serious.

　　 "Oreo got up to work!" Oreo, who was still lying on the ground, was also taken aback. He rushed up and couldn't help barking a few times when he saw the distance.

　　In Somo's field of vision, the distance that was originally the sun was shining brightly, but suddenly a piece of black mist that seemed to catch the sky appeared!

　　The black mist shrouded a piece of land, as if there were evil spirits overgrown, and it seemed to be a devastating disaster.

　　 Compared with the fog of the last time, this time the fog seems to be mixed with malice, the color is deeper, and it looks more terrifying!

　　 If calculated by distance, it happens to be less than one kilometer north of the underground refuge.

　　 Misty, Somo is no stranger.

　　 The ruins that I entered for the first time entered it through the mist.

　　 "The ruins suddenly appeared at this time, and there is no pattern of appearance at all!" While thinking about it, Somo came to the front door of the refuge and directly 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 bungee.

　　 There are good things in the ruins!

　　 And it’s 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 "Ma Gu", there are obviously more good things in the mist ruins.

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

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

　　 There seems to be an independent rule acting in the mist ruins, and even advanced things like the system will treat the things in the mist ruins as ordinary items.

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

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

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

not to mention...

　　 Looking at the water bottle containing toluene lying in the storage space, Somo's confidence is high.

　　 Oreo was already sitting in his seat first, and he buckled the seat belt with his mouth.

　　 As Somo put on his helmet and fastened his seat belt, with a bang, he bounced out of strong power and walked away.

　　 From the bird’s eye view of the wilderness, Somo is like a fearless warrior, driving a vehicle and rushing forward into the black fog.

　　Three kilometers...

　　 Two kilometers...

one kilometer...

　　 When the ruins were only 400m away, Somo stopped the car and tried his best to look at the scene in the mist.

　　 It's a pity, just like last time, the fog is thick and dark, and I can't see what's inside when I stand outside.

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

　　 Parked Bump into the garage, came to the front door, quickly flipped the large lock of the roulette, and with a click, the bolt received.

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

　　 came to the workbench and turned on the self-check switch.

　　 Taking advantage of the self-check, Somo 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.

"It only needs to react with toluene and sulfuric acid to generate p-toluene sulfonic acid, and p-toluene sulfonic acid reacts with sodium sulfite to generate sodium p-toluene sulfonate.

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

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

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

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

　　 After some more sulfuric acid was prepared, and phenol was introduced, phenol disulfonic acid was easily obtained.

　　 The sacred one brought nitric acid and nitrated the phenol disulfonic acid, and then trinitrocresol, the famous "picric acid" was released!

　　 Looking at the bright yellowish powder in front of him, Somo shook his slightly sore shoulder.

　　 The preparation of this set is extremely simple, and it also has the efficiency and focus of the workbench. It is estimated that Suma completed the production in less than two hours.

　　 The plain bitter taste in front of my eyes, its power is so scary!

The power of black gunpowder is only one-tenth of that of nitramine explosives~www.readwn.com~The power of nitro-ammonia explosives is only one-tenth of picric acid, which means that 1 catty of picric acid is equivalent to 10 catties of ammonium nitrate and is also equivalent For 100 catties of black powder!

　　 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 is just a comparison of "magnitude", the power of explosives is definitely not comparable to that of black powder!

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

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

　　 carefully packed all the picric acid in a small wooden cup and placed it in a place that is not easily accessible. Somo took out the iron block and began to make the final step:

　　 A crossbow arrow containing bitter taste!

　　 I want to go to the ruins and fight the monsters that can move with their broken spine. Simply using a crossbow arrow is of no use. Even if it hits the head, this kind of beast can continue to attack without fear of death.

　　 But if you fill the arrow with picric acid, you only need a few tens of grams. After being rubbed, shaken, or hit, it will explode with terrifying power!

　　Don't say it's a monster, even the iron skin can blast away, blast!

　　 took out a large glass of nether energy water and drank it, put on his mechanical arm, and Somo began to quickly make crossbow arrows.

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

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

　　 took it with bitter sour, carefully filled it into the groove of the arrow, and then glued it with tape and the small pieces cut from the plastic bottle. The explosion of the crossbow is done!
