Global Wasteland: Unlimited Upgrades for Vaults

Unfortunately, just like last time, the fog was thick and dark, and it was impossible to see what was going on inside from the outside.

After driving around the ruins for a while and finding that there was no end in sight, Su Mo returned to the base decisively.

Park Bengbeng in the garage, come to the gate, quickly turn the big wheel lock, and with a click, the lock tongue is closed.

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

Before coming to the workbench, turn on the self-test switch.

Taking advantage of the self-examination, Su Mo brought all the raw materials for making picric acid.

To make picric acid, phenol disulfonic acid is essential.

So making phenol from toluene is the key.

It only needs to react with toluene and sulfuric acid to generate p-toluenesulfonic acid, and p-toluenesulfonic acid reacts with sodium sulfite to generate sodium p-toluenesulfonate.

Sodium sulfonate reacts with sodium hydroxide to generate sodium p-cresol, and sodium cresol reacts with so2 to generate 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.

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

Putting the prepared phenol aside, Soma went on to make large quantities of sulfuric and nitric acids.

Wait until some sulfuric acid is prepared, and after passing phenol into it, phenol disulfonic acid is easily obtained.

Holy nitric acid was taken, and after nitration of phenol disulfonic acid, trinitrocresol, which is the famous "picric acid", was released!

Looking at the bright yellow powder in front of his eyes, Su Mo shook his slightly sore shoulders.

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

The seemingly ordinary picric acid in front of my eyes is surprisingly powerful!

黑火药的威力只有硝氨炸药的10分之一，硝氨炸药的威力只有苦味酸的10分之一，也就是说1斤苦味酸相当于10斤硝酸氨同时也相当于100斤黑火药！

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

Although this is only a comparison of "violence", the power of explosives is definitely not comparable to that of black powder!

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

In fact, the C21 explosives used by special forces in the 4st century are not much more powerful than picric acid!

After carefully putting all the picric acid in a small wooden cup and placing it in an inaccessible place, Sumo took out the iron block and started the final step:

A crossbow bolt containing picric acid!

If you want to go to the ruins to fight those monsters that can still move with a broken spine, it is useless to simply use crossbow arrows. Even if it hits the head, this kind of beast can continue to attack without fear of death.

But if the arrowhead is filled with picric acid, it only needs a few tens of grams, and it will explode with terrifying power after being subjected to friction, vibration, and impact!

Not to mention monsters, even iron sheets can be blasted away, smashed!

He took out a large glass of psionic water and drank it. Putting on the mechanical arm, Su Mo began to quickly make crossbow bolts.

For close combat use, crossbow arrows do not need to be carefully polished, as long as they can be fired stably within 20m, they are excellent products.

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

Take the picric acid, carefully fill it into the groove of the arrow, and then stick it with tape and the small pieces cut from the plastic bottle. The explosive crossbow bolt is done!

On the shelf testimonials! !

Think back ten years ago.

The author’s home is in a small town at the foot of a mountain, and his father opened a tofu shop to barely make ends meet.

When I first learned to drive, my father would let me drive to deliver tofu to buyers!

I have an old 86 at home, and every day I drive it up and down the hills to make deliveries.

Not only was my speed slow at the beginning, but the tofu was broken every time it was delivered!

Every time I come back, my father will beat me!That's a real fight!There are marks of being drawn all over the body!

In this way, the beatings from junior high school to high school gradually decreased a lot.

After high school, I fell in love with writing, and tried to write some very "formal" texts by hand, and submitted them to major newspapers and magazines, hoping to get some manuscript fees.

My father beat me up after hearing this, thinking that I was not doing my job properly.

However, he didn't know that at that time my driving skills had greatly improved, and it only took me 15 minutes to drive around the mountain!

and!

Not a single piece of tofu was broken!

(??▽?)?!

In the third year of high school, I met a girl from the same school. She was very beautiful and spoke well.

Every day, she would praise my writing for being beautiful, so I secretly saved money to buy gifts for her!

As time passed, our relationship became better and better. I saved half a year's manuscript fee, bought 99 roses, and then I confessed to her affectionately:

"Natsuki! Be my girlfriend!"

She shook her head and told me that I was still young in high school, if I went to the same school in college, she would agree!

At that time, I was full of motivation, and every day was as exciting as a chicken blood...

until...

One rainy day, I was driving the car of the tofu shop, and saw her get into the big car of that middle-aged man with my own eyes!

Tears blurred my eyes.

But what hurts my heart the most is that she praised me for my good writing. Could it be a lie! ! !

Does she feel that writing novels is a dead end?

I didn't go after it, I know... No matter how fast the 86 is, it can't catch up with Xia Shu who is sitting on the Mercedes.

Well, the above is purely the roar of the author, and I am not Takumi Fujiwara. Of course, the feeling of not being recognized after writing for so many years is really terrible!

I have been trying to contribute since I was in high school, and the most I got was 300 yuan. At that time, I invited my brothers out for a barbecue, and I paid 150 yuan for drinking! (cover your face!)
