talk about the case

[Kingman Brewster Jr. (American educator, diplomat, former president of Yale, 1919-1988): Violence cannot give people lasting hope, it can only make people temporarily restless. 】

Kan gave him a contemptuous look, "Idiot!" He came to this place unknowingly during the fight, and when he woke up, he saw fire and Li enchanted in the manuscript.

Li told Kan that he passed out from exhaustion and that he would be fine when he woke up.

Yan Queqing took a look, all the good guys came.

Kun quietly came to Xiuran's side, his eyes wandered between the two of them, and he raised his eyebrows at each other—they?

Qian nodded and hooked his thumbs towards the backs of the two.

Kun's lips curled up slightly - the young master is doing well!He turned his face and returned to report the situation with a blank expression.

It turned out that Haofeng found the exact location of the iron mine through the things left by his father. The grandfather came here with a mighty force, but the situation was unknown. They were waiting outside the tunnel, and only the guards came in.

In addition, Jinyu himself insisted on following, the reason is - Hua Li is here!

With a sound of annoyance, Zhen had no choice but to keep him by his side and protect him firmly.

The only difference is that they took a safe path through Xiao Bai's guidance, probably opened by the mysterious man and the alchemist, while Yan Queqing and others took the most dangerous path, and the room was completely confusing.

After the report, Kun asked, "Then, young master, do you need to call the grandpa and the others in?"

Xiuran looked at Yan Queqing with a questioning gaze, he thought for a while and shook his head, "Find Knife Mountain first, there are always people waiting in the huge tunnel, but we haven't seen anyone except those monsters."

After Kan woke up, he excitedly joined the ranks of research, while the rest of the people watched and played curiously.

Yan Queqing came to the desk to look for useful clues. The items on Nuoda's desk were in a chaotic order, all related to alchemy. This is undoubtedly Huangbai's cave, but is the alchemist in Tongcun really Huangbai?

When Yan Queqing saw the cup and brush on the left hand side of the desk, he thought of that scrawny little girl.

Xiuran saw that he was thinking hard and didn't bother him, and stood silently behind him, but would go to him as soon as he needed it, with the tacit understanding of an old married couple.

Qiqi on the side looked at the pile of radishes in surprise, hugged the big radish and asked Mr. Wen, "What is this for?"

"Oh, isn't it strange that Pottan needs radishes to refine it?"

"Yes, what is that pot of nitrate?"

"Something that makes gunpowder."

"It's like this." Qi Qi left with a few big radishes in her arms, um, I haven't eaten radish cake and pickled radish for a long time, Xiao Hei saw it and stuffed two big radishes into the storage space.

But the multi-handed Sunda was much more naughty. He took the iron mill and beat it twice in the stone mortar, and there was a bang, and an explosion occurred.

Old Wen jumped up and said, "That's nitrate. Once it rubs against iron or stone and sparks are generated, the disaster will be unimaginable. Fortunately, you are a cultivator, Xiao Lizi, you must not touch it!"

Then be vigilant, "Qi Qi, Xiao Hei, don't run around, it's dangerous here, don't touch things, okay?"

Qi Qi and Xiao Hei nodded obediently, seeing Huo Shu and Mr. Wen chatting enthusiastically, they followed curiously.

Wen Lao said, "He proposed a method of smelting gold from different gold mines: in the Duoshui gold mine, first separate the quartz sand to float, and then calcinate the silver-containing gold foil obtained by Huanggong and Hutong laws. The Duishan gold mine uses gold Essence, gallbladder essence, cinnabar and other medicines are smelted."

Huoshu said, "In addition, he also proposed a method of smelting tin ash billet furnace, smelting gold and silver ore powder and lead together, separating the lead lump soaked with gold and silver, and blowing off the Mitu monk after roasting, thereby purifying gold and silver. .”

seven seven...

Xiao Hei's eyes were circling, Qi Qi hugged Xiao Hei and silently walked away from this place that made him feel very stupid.

Zhen found something in an earthen cauldron and sniffed, "Is this poison?"

Jinyu stepped forward to check and said, "Five poison prescriptions?"

The laymen finally heard something they were interested in. "Poison?"

"It is said that the Five Poisons formula is made of stone gall, cinnabar, realgar, 礜石, and cishi. However, the materials and process have always been a mystery, and even the antidote has never been heard."

Zhen's mouth twitched, "I said he still let people live, and even worked out the mysterious poison formula."

Everyone didn't know, Huoshu and the others threw themselves into the manuscript and looked through it without knowing the time.

Jinyu kept reading the materials, "He also sorted out the medical effects of the products he developed."

Li picked up a stack of books thick enough to be thickened by his thighs, and exclaimed, "Ah! The Classic of Hardware."

As soon as the words were finished, the book arrived in Huoshu's hands, and Lao Wen arrived very quickly. One must know that Huoshu's cultivation base is [-]% higher than him. It seems that people have great potential.

The classics of hardware include "Fire Dragon Classic", "Wu Jing Zongyao", "Shen Nong's Materia Medica", "Dan Jing", and "Golden Slips".

For example, the Huolongjing recorded various gunpowder formulas and gunpowder weapons in detail successively. It is an important document for the study of gunpowder.

The Book of Hardware has long been lost, but I didn't expect it to still exist, although the content is missing due to its long history.

Huoshu hugged the book and cried loudly, "Master! Master, I finally found it, I finally found it."

Hua Li felt very strange, "Isn't "Shen Nong's Materia Medica" sold?"

Li explained, "Some of the content has long been lost, and this is the most complete one I have seen." Then he plunged into the book and couldn't extricate himself.

"I didn't expect to see it in my lifetime. I really have no regrets in dying." Jinyu was so excited.

"But it has nothing to do with gunpowder."

Huoshu regained his composure, touched the book cherishingly, and replied, "Many things in the world are connected, but people are too arrogant and mistakenly think that what they see is everything. In fact, the birth of gunpowder is closely related to herbal alchemy."

He opened a page randomly, "For example, this Hu powder is also lead powder, called Huang Dan in ancient times, its golden color was valued by early alchemists, and it was called "Xuanhuang". Just shine."

Jin Yu excitedly continued, "That's right, realgar and orpiment have always been regarded as the key medicines for alchemy. "Shen Nong's Materia Medica" listed realgar as a middle grade, saying that it "can transform gold, silver, copper and iron". It is known to corrode all kinds of metals. Without the investigation of all things by doctors and alchemists, it is unclear whether gunpowder can be born."

Zhen was puzzled, "Please speak humanly."

Wen Lao was amazed, "This Huangbai is too powerful. He has enhanced the purity and speed of refining. This is not just a simple improvement in quality and speed. It saves labor and raw materials, but it makes weapons and gunpowder more threatening."

"He is a genius, a genius that is rare in a thousand years." Huoshu nodded in agreement, it was rare for him to praise someone.

Then they got together and said some strange things, and everyone left quickly.

At this time, Hua Li was walking around a stone wall, which was very different, it was made of stone bricks, Yan Queqing and Xiu Ran walked over to him and asked him "what's the matter."

Hua Li kept touching the stone wall and said, "There seems to be a door here."

"Oh!" Everyone gathered around curiously when they heard this.

At this time, in front of the monster house, Mei Qinghua showed a nervous expression, "Sister, let's go, they have all been found."

Mei Yuhua smiled contemptuously, "Who knows that I am the real alchemist except you, I won't leave, I want to watch Haofeng be poisoned to death, watch the palace be blown into a pile of mud! Hahahahahaha, who can stop, who can Prevent!"

Finally, Mei Qinghua sighed, "Are you going to find them now?"

"That's right, we are innocent children caught by Huang Bai, who would doubt us." While speaking, he tore his clothes, cut his arms and thighs with a stone, and made himself look like he was fleeing.

Hua Li said that the stone wall may still have a mechanism, but he didn't know how to open it. Huoshu got up from the manuscript when he heard it, took out the water pipe, took a puff of smoke and sprayed it on the stone wall. Smoke, smoke hit the wall and spun around.

"Smoke is like water, as long as there is a little gap, it will get in." Move a step and repeat the smoke, and suddenly the smoke disappears mysteriously, only a few traces of smoke are left in the air, and the rest are squeezed into the gap between bricks in the crevice.

At some point, the rest of the people also gathered around, and Xun exclaimed, "Trap door!"

Xiuran kicked at the gap, and the stone door opened slowly by rubbing against the ground. Xiuran entered first, and surprise flashed across his coldest eyes.

Yan Queqing and the others became anxious when they saw Xiuran standing still in front of the door, "Xiu?"

Xiuran confirmed that there was no danger before letting Yan Queqing in.

After entering, everyone was frightened by what they saw.

"Oh my God……"

This cave is full of weapons, endless weapons in sight.

Round like a bronze drum, more than ten feet long, the red cannons used to defend the city; the smaller generals and second generals; There are many leads coated with alum oil.

Three-eyed blunderbuss, Baizi Lianzhu cannon, shield, Hunjianglong, bird blunderbuss, shotgun.

On the right side are all neatly arranged swords, sticks, guns, bows and arrows, as well as some alternative weapons, such as duckweed crutches, meteor hammers, halberds...

As well as a large pile of mineral raw materials such as saltpeter and realgar, as well as hundreds of boxes of neatly stacked ammunition and gunpowder.

Qian hurriedly extinguished the torch in Hua Li's hand.

Hua Li said, "Hey, these are just ordinary things."

Can continues "Idiot."

Yan Queqing kindly explained, "Separation is of course not worth mentioning, but if so many explode, even practitioners will be hard to stop. If the cave collapses, it will be difficult to escape."

Hua Li touched his head, yes, unity is strength.

Finally, I understand how Haofeng, who has always been wise, is reluctant to kill this enemy's battle cannon. This is a proper mobile weapon.Huang Bai, I can't hunt you down friendly.

Wenlao and Huoshu were not very interested in the weapons of the mortal world, so they continued to work on the manuscripts. Anyway, the recipes for these weapons were all in the manuscripts.

Gen hugged Qi Qi and Xiao Hei and didn't dare to let them move. If the child's cultivation base is too low, he will be seriously injured if he survives the explosion.

Hua Li was deeply shocked when he saw weapons such as the God Arm Bow and the Enemy Crossbow. "This is from Ye's army." But for a few hundred pieces, Hua Li and Hua Yi looked stern - the Emperor's Kingdom has traitors.

Seeing Hua Li's actions, Kan also came, pointed at the wart scales and said, "This is also unique to the Emperor's Kingdom."

Hua Li looked over and nodded heavily.The production of these weapons is a first-class military secret of the Ye family army. Like the Zhuge crossbow, it is light but can fire ten arrows in a row. It is very useful whether it is walking or riding a horse. It is perfect for attacking the enemy. Under Zhuge's crossbow arrows.

There is also a crossbow machine to look at the mountains, which is even more amazing. It has precise aiming, long range and can expand the user's field of vision to detect the movements of enemies in the distance. This is something that only the elite cavalry of the Ye family army can have.
