After Shangwen read the memorial, he got on the car and went to the Qin Palace. Zhao Gao leads the way. Shang Wen followed behind.

As he walked into a hall, Shang Wen saw what King Qin was eating. It's probably a midnight snack. It's already late. Shang Wen thought so. Shangwen was taken aback when he walked in. That is the pill of ancient legends.

For a moment, Shang Wen felt that he didn't know what to say. I don't know what to do. According to historical rumors, the first emperor of Qin was killed by taking pill, and the main ingredient of this thing is metallic mercury. To put it bluntly, it is also the first ingredient in cosmetics. It only has a temporary effect. As for the ingredients of other pill. Shang Wen doesn't know. But to sum it up. This is not a good thing.

"Mr. Qin is here. Sit down." King Qin saw that he was taking the pill. It's no surprise that Shangwen greeted Shangwen to sit down.

"Wang, this, this pill, it's better not to take it." Shang Wen persuaded.

"Oh. Why?" King Qin said with a relaxed attitude.

"This substance is a heavy metal, long-term use, must, must..." Shangwen understands that if people's life span is inevitably affected, this is a big taboo. This is to be decapitated.

"What must be?" King Qin asked.

"It must be harmful to the body. In fact, this is a chemical agent. This alchemy secret technique is nothing but a futility." Shang Wen said.

"Oh. So, your husband has also studied this alchemy," Qin Wang asked.

"This alchemy is just one of the chemistry." Shang Wen replied.

"Chemistry?" Qin Wang said.

"Yes, chemistry is to change the original material properties of one or several substances through a certain method. It is called chemistry." Shang Wen could not come up with a thick dictionary to explain to King Qin at this time, so he had to So particular. Anyway, the meaning is almost the same.

"These methods include a variety of methods, such as distillation, dry distillation, dissolution, etc.. These are all chemical reactions to produce a new substance." Shang Wen said.

"Oh. Speaking of it. This pill seems to be like this." King Qin suddenly realized.

"Speaking of which, the changes are endless. It takes several generations to discover the mystery of these substances. These substances have different properties and different applications. It is like this glass." Shang Wen said, pointing to the case. Said the glass.

"This is chemistry. Put in several different substances to produce a brand new substance. But this thing is good or bad. It is toxic and non-toxic. It is difficult to be sure without long-term testing. Therefore, the king still stopped taking these. Pill." Shang Wen persuaded.

"This." King Qin hesitated.

"This elixirs contains heavy metals, especially mercury, and that dansha is mercury sulfide. A small amount of this mercury has a certain effect, but long-term use will inevitably cause serious damage. The final symptoms are... Shang Wen wanted to explain the symptoms of mercury poisoning in detail.

"What?" King Qin asked.

"Mental disorder, tooth loss. And body joint pains. Finally, finally..." Shang Wen didn't dare to go on.

"Wow." With a wave of his arms, King Qin knocked all the pills, pen and ink on the case table to the ground.

"Come here, pull out all those alchemists and bury them alive." King Qin shouted loudly. Shang Wen saw that King Qin was very angry about this. Shangwen couldn't say anything when he saw this. After all, it is better to say less at this time.

"Here." Zhao Gao hurried away.

After waiting for a long time, it is estimated that King Qin's anger has almost disappeared. Shang Wen also knew that he could not talk nonsense at this time. Besides, King Qin's move is probably to bid farewell to the pill. Even in modern times, medicine cannot be taken casually. Especially chemical agents. no side effects. That's to blame. The elements of the human body are relatively balanced. If one of them exceeds the standard and breaks the balance, the result will appear sooner or later. It's just a matter of time.

"Thank you, Mr. Qin." King Qin turned around and bowed to Shang Wen.

Shangwen didn't dare to say much. Also worshipped.

"Widow will not take this medicine anymore." King Qin said explanatoryly.

Shang Wen smiled and nodded.

"Wang Shang, now we have the arms orders from the country of Yan, but it is still difficult to meet the current needs." Shang Wen continued. Shang Wen deliberately changed the subject.

"Oh. What's the difficulty?" King Qin asked.

"Barrel." Shang Wen said straightforwardly.

"The barrel is very difficult to process. Basically, it depends on casting, but when casting, it is inevitable that bubbles will be generated. This leads to problems with the entire barrel. Only those skilled casters can complete these technical requirements. Those castings The division has to complete the casting of artillery. It is difficult to complete such a large-scale production in a short time. In addition, our Qin army will also be equipped with this kind of weapon, but this kind of weapon is in accordance with the current situation. I am afraid... "Shang Wen said embarrassedly.

"I'm afraid of something". King Qin asked.

"I'm afraid, according to the current situation, it will take at least ten years for our equipment to be completed on a large scale." Shangwen's figures are derived from statistics. The Qin Army has almost one million troops in the country. The standing army is only 300,000. However, according to the current production rate of barrels. Basically a fraction of this number. And the quality problem is also very prominent. According to Wang Ben’s knowledge, the barrel of the gun began to become hot after several consecutive shots. Can't shoot. At any rate, the tactical queue temporarily made up for this shortcoming. Moreover, the barrel has a life span, and replacement and maintenance require a large number of spare parts. At present, our own production can't be completed at all.

"So long." King Qin said.

"Yes." Shang Wen nodded and said.

"Then Mr. Qin must have a solution?" King Qin asked rhetorically.

"This, this." Shang Wen touched his mouth with his hands.

"This must be solved with technology. According to the current processing technology, it is simply impossible to satisfy. Chen had planned to transform the machine tool the day before, but the effect was not very obvious, and many machines were still lacking. But Chen was willing to give it a try." Shang Wen said. In fact, Shangwen felt that he could only do this. Because many things cannot be done by humans. First of all, those mature craftsmen. If you rely on continuous craftsmen to teach, more than two thousand orders can be completed in a short time. It is estimated to be difficult. Now there is only one way to improve technology. The problem of the barrel must be resolved. Not all six countries are equipped with a large number of muskets. With the export of the musket. The six countries that have benefited will certainly imitate them in large numbers. In the face of imitations, Qin Jun did not have such equipment. It must have been severely hit. Such a situation must never happen. The difference between weapons is an algebra. It's just a joke.
