In the Rejuvenation Hall, Dr. Dong's consultation table put the latest edition of "Mainland Observations". Pen "Fun" Pavilion www.biquge.info she will read a book in her free time, "Mainland Experience" contains a lot of anecdotes and various current events that have happened in the past month, which is a good choice to pass the time.

When she saw Chen Xiao's name frequently appearing in the book, she was also stunned.

At that time, the guy who was greedy for life and afraid of death would still make up these things?

Thinking of Chen Xiao's hateful face, Doctor Dong couldn't help but laugh, and couldn't help but have a trace of the urge to meet that guy.

"Prepare a dragon cart for me. Physician Dong said to the guys working below, "Bring some common medicines." I'm going to travel and give medicine. She remembered the potion she had prepared for Chen Xiao before, and took this opportunity to hand it over to Chen Xiao.

"If it's true in the books, that guy deserves to be talented. Physician Dong looked at the report on the Battle of the Fish-Man in the "Mainland Experience", and his eyes were far-sighted.

Chen Xiao didn't know what was happening in Leighton City far away. At this time, he was about to enter the karst cave of Bailong Mountain and mine the phosphate rock.

He ordered the guards to put on airtight fur clothes and bring airbags into the cave. The air sac is used for breathing, and it is filled with oxygen that he uses to electrolyze water in an electrolyzer. This oxygen is highly pure and can be maintained for a long time.

Entering the cave again, Chen Xiaocai carefully observed this natural cave. At the top of the cave, there are stone stalactites hanging down, there is the magic of the devil's axe, because of the limestone weathering and the formation of the stone curtain, such as the waves, the clouds hang high.

The temperature is very low, the air is humid and oxygen-devoid, and there are no other creatures living here. He came to the place where the hairball was nesting, and the gray-brown rock was still the same, glowing with a little phosphorescent in the sunlight.

This piece is not ordinary phosphate rock, not ordinary calcium phosphate ore, but high-purity phosphate rock containing simple yellow phosphorus and red phosphorus, so the last time he rubbed his feet against the phosphate rock, he would send out sparks.

If it weren't for the low temperature and humid air, this high-purity phosphate rock might have turned to ashes. He ordered people to wet the phosphate rock with water, clean the surface of the dirt and stones, and then carefully excavate it.

It wasn't until the evening that Chen Xiao finished excavating this high-purity phosphate rock, and he still had a trace of luck, maybe the rocks inside also contained this kind of phosphate rock, but after exploration and excavation, nothing was found, this piece of phosphate rock is not connected to the rock of the cave, maybe it was transported from other places.

Thinking of this, Chen Xiao couldn't help but think about it and was extremely frightened.

If that's the case, the hairball's life experience is not simple. It's a pity that the lazy guy is still sleeping at home.

Except for the first bite of his blood, the guy was fine, usually falling into a deep sleep and waking up to eat. That guy has a huge appetite, he eats everything, and as long as he can put it in his mouth, the hairball will open his mouth and swallow it in one gulp.

After returning to Rodri Village, Chen Xiao went into the laboratory and began refining phosphate rock.

The yellow phosphorus and red phosphorus in it can be freely converted by temperature. Yellow phosphorus, which is highly toxic, ignites at 40 °C, and will spontaneously combust at a high temperature, which is very dangerous, a small amount can be stored in cold water, but a large amount is not, so he has to convert the yellow phosphorus into red phosphorus for preservation.

The conversion device is a sealed iron can, after heating at 400 °C, yellow phosphorus will be converted into red phosphorus, red phosphorus has low toxicity, and the ignition point is as high as 200 °C, easy to preserve.

What's more, what Chen Xiao needs to use is red phosphorus.

He now has too few means of self-preservation. Except for the detonator, there seems to be nothing to get hold of.

Caustic soda is corrosive and has a very limited effect.

Saponaria extract is highly toxic to fish and fish-people, but it has little effect on people.

The chlorine gas collected before was a highly toxic substance, but the amount was too small, and he used it to react to make calcium chlorate and other substances as bleaching powder.

As for hydrogen, he made hydrogen balloons one by one and gave them to Karen and them to play with.

Nowadays, yellow phosphorus is a highly toxic substance that can be used as a backup poison, but yellow phosphorus is not easy to store, is prone to spontaneous combustion, and can only be used as a trap.

Red phosphorus is different, red phosphorus combustion produces a lot of smoke, and the effect will be very good when combined with black powder to make smoke bombs. As soon as the smoke screen comes out, you can not only attack by surprise but also escape, which is a very good means of controlling the scene.

In addition, red phosphorus can be used to make safety matches, and it is much easier to light a fire. Flint and fire folds can be eliminated.

When it got dark, he lit an alcohol lamp, made a cup of milk tea to refresh himself, and continued to prepare smoke bombs. He had no experience in preparing smoke bombs, only knew the principle of making smoke bombs, which was to use red phosphorus to produce white light and a large amount of smoke when burned.

Potassium chlorate is a dynamite agent, very lively, a little exposure to the sun will produce an explosion, Chen Xiao plans to make some potassium chlorate for later use. He was very careful, because this thing was too dangerous and lively, and it was also so poisonous that he would even be injured if he was not careful.

Fortunately, he has a lot of instruments and equipment here, plus he usually prepares a lot of chemicals, and has a ready-made electrolyzer, so it is not difficult to prepare potassium chlorate. Once all the ingredients are ready, the manufacture of smoke bombs is a breeze.

The iron barrel from which the detonator is made can be used as a carrier for a smoke screen.

The night passed quietly. When Chen Xiao finished five smoke bombs, he realized that it was already dawn.

After rubbing his eyes, Chen Xiao left the laboratory and went to the steamed bun shop to eat a few steamed buns. Under the care of Wendy and her family, the steamed bun shop is well organized, and Chen Xiao can't help but sigh that he didn't invite the wrong person before.

These three maids are capable and diligent, which is really helpful.

Wendy looked at Chen Xiao with some distress, handed hot water and towels to Chen Xiao, and said, "Master, you have become a panda." "Wendy has never seen this panda, and I always heard Chen Xiao say that he has two panda eyes, so he said it according to the gourd painting scoop.

Chen Xiao wiped his face with a towel and said with a smile: "You still know how to joke with your master." There is growth. Yes, I'll go back and catch up on sleep. Something called me. ”

Wendy grinned, and her praise for Chen Xiao was very useful.

Alan rushed out of the kitchen, hugged Chen Xiao's arm, and shouted, "Master, I want to take a leave, is it okay?"

Her already developed breasts rubbed against Chen Xiao's arm, feeling the soft touch, Chen Xiao couldn't help but blush, and said strangely: "What kind of leave?" Speaking of which, the three maids have never asked for leave from themselves.

Allen's face flushed, her face was shy, and she couldn't explain it clearly. Wendy smiled disdainfully: "Do you have an appointment with a handsome guy?" ”

Dating a handsome guy? Chen Xiao raised his eyebrows, and his mood suddenly became bad. I bought a watch last year, what bastard would dare to soak my maid?

Alan blushed and said, "Master, is it okay?"

Chen Xiao looked at Wendy, the intellectual and shrewd Wendy has become Chen Xiao's right and left hand. Wendy smiled: "That handsome guy is said to be a noble young master. He's so handsome. Alan, it's not me saying you, it's unlikely that you're going to be able to. How could a noble young master take a fancy to us lowly civilians. ”

Alan lowered his head, bit his lip and said, "I believe there is true love." ”

"Crying alone, true love is invincible!" Chen Xiao complained, and looked at Alan seriously. is at the age when love is beginning to bloom, and Alan falls into the sweet trap of love so easily, Chen Xiao understands it very well.
