Chapter 823 (2/2)

The teacher's palace was a little embarrassed and said, ”it's difficult to prepare real water, and it's even harder to preserve it. It still needs less time for the master to allow his disciples to buy the needed external medicine of gold and stone and refine it.”

Wang Chen just said faintly, ”but you need to remember that the lives of your teachers and disciples are related to this matter. If you are slow, I don't need to punish you. The people in the Shangqing palace will clean you up!”

The teacher palace knew whether it was good or bad. All the gold, stone and external medicine he needed for cultivation had their own channels. He took the silver and went there. When it was dawn, he brought a carriage with a lot of gold, stone and ore, and even two pieces of pork. The teacher Palace ordered the two frightened and timid fools to cut off the fat on the two pieces of pork and take it to oil refining.

Carrying a bucket of mysterious liquid, he carefully carried it into the room and opened the lid. Wang Chen smelled a pungent smell and asked the master's palace. This is what he just said about ”bone etching real water.” the master's palace explained: ”Bone etching water was called green alum oil in ancient times. Only before Taoism became holy could it be prepared with rice vinegar and green alunite. Later, bone etching water gradually became used by people and became an important foreign medicine of Taoism. Only then did real people extract this real water from iron ore by secret method.”

Speaking of iron ore, Wang Chen suddenly realized that this thick liquid seems to have no taste, but it has a faint special stimulating feeling - isn't it sulfuric acid?

Wang Chen's face was numb, pointed to the bucket of concentrated sulfuric acid with impurities and asked, ”is this what you call bone etching real water?”

The teacher Gong didn't know why he asked, and replied nervously, ”exactly!”

”It's really enough to etch the bones...” Wang Chen continued with a faint chill: ”is the Wanhua thunder water as corrosive as the real bone etching water, and it is refined from saltpeter?”

The teacher Gong was surprised and replied, ”the founder's magic eye is the same, indeed!”

Wang Chen said excitedly, ”it's really creative to call nitric acid Wanhua thunder water... Nitric acid is the mother of explosives. Almost all explosives need nitration reaction. No wonder it's called Wanhua thunder water. Nitration reaction with oil - isn't that nitroglycerin? Arctic Zhenlei... Nitroglycerin? What's earth Yin Zhenshui? Is interior Zhenlei picric acid or RDX?”

The teacher's palace replied in a muddle headed way: ”the real water of the earth's Yin is refined by the Xuanyin earth evil spirit, and the Xuanyin earth evil spirit... It was called oil and fierce fire oil in ancient times. It is condensed by the Xuanyin evil spirit at the bottom of the earth, such as oil, black and thick, and glows in case of fire.”

”Petroleum!” Wang Chen took a breath: ”the cornerstone of chemical industry! You have all learned to refine petroleum!”

”Several kinds of real water can be obtained by refining xuanyindisha, but it is controlled by the imperial court. Only a few top secret mines can produce it.”

Wang Chen looked at the Shichang palace as if he were looking at a living Protoss. Only now did he understand why the secret script of Lei FA's Taoism said that Lei FA's illegal force was uncontrollable and ordinary people were broken to pieces.

Aggressive Taoists are people who make nitroglycerin explosives by hand - at this level, they are also those groups who want the government to maintain stability and unity in the 21st century! It seems that the painting style of Taoists in this world is wrong.

At the thought of this, Wang Chen has some numbness in his feet and is almost ready to run away. Anyone who is surrounded by a Taoist priest who is treating saltpeter with concentrated sulfuric acid to prepare Wanhua thunder water nitric acid, while the other side is refining oil to prepare saponification reaction, and then refining oil with Wanhua thunder water to produce Arctic true Thunder - nitroglycerin should have this reaction.

Nobel once sacrificed Arctic thunder like this - later, he blew up his two younger brothers, his father was seriously injured and he was disabled.
