Liu Yu arranged for Wu You to do the work of making sulfuric acid, mainly because he was able to see his attainments in alchemy, that is, chemical research. He would lead the following people to make the craftsmen of the Military Industry Institute earlier. Liu Yu was not prepared to let Wu You stay in the Military Industry Institute for a long time. Wu You was the kind of stubborn man who liked to work behind closed doors.

Liu Yu and Liu Liniang returned to the house outside the palace directly. When he came back, Liu Yu was already very sleepy, but after sitting down and drinking a cup of tea, Liu Yu was not sleepy.

He kept thinking about what Master Wuding's face changed after he boldly guessed yesterday. In fact, Liu Yu wanted to confirm one thing more, that is, if he hadn't been there, the history of this world would develop.

If it weren't for Liu Yu, the old emperor would have passed the throne to the seventh prince, that is, King Su Zhe of Chu. Su Zhe had a trick in his heart and was a tough character who could fight against King Huai. But Su Zhe was young and energetic after all, and there were not many capable people around him to help. If there were no Huo Bing, without Qi Fang and Zhang Wuzhu, relying solely on He Mao and others to assist, the result of Su Zhe fighting with King Huai would sooner or later be defeated.

Then there is a question: Why does King Huai have no emperor's appearance, but Princess Min has it?

Liu Yu boldly assumed that if he had not been there, the King of Chu would have successfully ascended the throne and would have broken up with King Huai in a short time. Because King Huai would not tolerate Su Zhe to settle down, he would definitely launch a rebellion when he was not stable and his troops headed north. This was also confirmed after Su Yan ascended the throne. King Huai had been waiting for more than ten years and he had been impatient. It was this impatient that the flaw exposed by the Huai Army.

King Huai was too eager to succeed.

In this way, the Civil War would be very beneficial to the Huai Army in the early stages. The court was trapped in a passive defense situation. This would also be very similar to what happened in reality. In reality, Liu Yu arranged defense on the one hand, but pushed Su Yan to the front line as "cannon fodder", attracting the main force of the Huai Army to besiege Xuzhou City, thus winning time and providing time for him to go south to launch a sweeping supply line behind enemy lines.

Su Zhe obviously would not have such great courage, nor would he do not have Liu Yu's muskets and earth cannons as backing to launch this battle behind enemy lines. Su Zhe could only follow the steps. The only difference is that Su Zhe is more tolerant than King Huai. He would even guard Guanzhong and give up the whole world to King Huai, and waste his life with King Huai to the end.

Guanzhong occupied natural dangers, and the high walls of Tongguan and Chang'an City could be consumed for a long time. Taking a step back, even if Guanzhong was lost, Su Zhe could still follow Emperor Minghuang of Tang to travel far away from Guanzhong and wait for an opportunity to make a comeback. As a rebel and eager to succeed, the King of Huai must have been determined to break through Chang'an City. He ignored most of the cities and border passes in the north. This would create a situation where the army was in deep. As long as Su Zhe did not die, the guards and soldiers loyal to the court in the gate and northern cities could also launch a counterattack.

After all, the imperial court area was greater than that of Huai. Even if the Huai army was brave, it would not withstand long-term consumption.

Once a stalemate is in a state of affairs, it will become a common pattern in history, and will last for several years, and then the orthodox people will help them to wipe out the other side.

Liu Yu thought, could it be that Su Zhe killed King Huai? Only after the Huai King's daughter, Princess Min, was in power, would the Huai Army change its strategy, annex Guanzhong, conquer Chang'an City, and then Su Min becomes the queen?

There was no result, but Liu Yu was in a daze. It was not until Liu Liniang walked out with a tired look on her face that Liu Yu turned her eyes on the lazy and charming Liu Liniang.

"Twelve Young Master, didn't you say you were sleepy and you should have to rest early?" After taking a shower, Liu Liniang went to the room first. After waiting for a long time, she didn't see Liu Yu coming over before she came to take a look, but saw Liu Yu sitting alone at the table in a daze.

"I'm thinking about something, but I can't sleep." Liu Yu sighed, "Li Niang, now I really want to go and see how that heavenly book is written."

Only then did Liu Liniang realize that Liu Yu was struggling with the matter of Tianshu, so she sat down next to Liu Yu and drank a cup of tea: "Twelve Young Master, I want to help you too, but unfortunately my junior sister didn't know where she went. Otherwise, I would bring it with her and show you the Twelve Young Master, so I don't have to make you lose your mind like this."

Liu Yu said with displeasure: "Your master said that you would reveal the opportunity to spread the five thunders. Are you afraid that I will be struck by lightning. Are you a widow?"

Liu Liniang smiled and said, "My junior sister has been taking it for so long, isn't it still good? If you are afraid, I will watch it with the Twelve Young Master."

Reading the Book of Heaven together, being struck by lightning together, and having a common taste of life and death. This is also a kind of love saying.

Liu Yu and Liu Liniang remained warm for a while, and Liu Yu sighed: "In two days, the family will be back. Maybe there will be less time to come out to accompany you. There will be less meetings."

When Liu Liniang heard this, her face felt a little disappointed and said, "That Twelve Young Master, don't you seize the time and cherish my family?"

Liu Yu immediately picked up Liu Liniang and walked towards the inner room. Life is full of joy. Before the past is resolved, Liu Yu did not think about future events.

…………

After waking up, Liu Yu became much more energetic. Before dusk, Liu Yu went to Shangshutai to check the situation.

When I arrived at the Shangshu Deck, I learned from Sui Yu that Western merchants had arrived in Chang'an City and could meet Liu Yu at any time.

"So fast?" Liu Yu was a little surprised.

Sui Yu said: "This group of Western merchants came to Guanzhong to traffic in a batch of silk. They were very familiar with the path of the Central Plains. They did not expect that the court would approve them to go to Guanzhong to do business freely. Therefore, they came here as soon as possible after getting the news."

"Then let's arrange it and meet today."

Liu Yu was in a hurry to do things. Since he knew that the Westerners had come, he didn't want to waste time. He met these Westerners first.

The place where Liu Yu chose to meet was at the Guoyi Hall. Western merchants sent two Chinese-speaking representatives, one named Huston and the other named Piss. Both were in their thirties and tall Westerners. Among them, Huston was still a bearded man and smiled like a top.

"Hello, hello. Prince of Shunchao, what's your name?"

Pis looked very enthusiastic, and as soon as he came up, he greeted Liu Yu in not very fluent Chinese. If Shunchao people met Liu Yu, such an opening remark would be very impolite, but the two Westerners said this, which made Liu Yu smile. Westerners are not as polite as the Central Plains people.

Liu Yu didn't feel anything, but went up to shake hands, as if he was very familiar with the etiquette of Westerners. Not only did Huston and Piss feel surprised, but even Sui Yu and several officials of the Ministry of Rites who were with Liu Yu were also surprised.

"Oh, the prince of Shunchao, you look much easier to talk to than those officials. They not only like silver but also like gold. They are not like you, they are very enthusiastic. When I go back, I will definitely tell my Chinese people that you are a good prince."

After being in China for a long time, Piss also learned to flatter. Such a flattery will not appear to be very artificial. At the same time, he also demeaned the officials of Shunchao, saying that they are just greedy people.

Liu Yuxin said that those officials are not only greedy for money, but also lustful, but you are just rich and have no lust.

Both sides sat down, and Liu Yu asked Jason directly about his situation, wanting to know if these people knew his old friend.

"Jason? Prince said that the one who has a short nose and likes to walk in Central Land?"

"It should be." Liu Yu thought about it, but he was not sure. After all, there are many Westerners with similar names. It is not easy for these business people to travel around the world to get to know each other.

"He's here, he's here. He's in the eastern port, but he hasn't arrived in the Central Plains yet. He said that he knew a friend who was an official in the Central Plains. He didn't expect that he was the prince. Haha, he's not bragging. It's too awesome." Piss shouted excitedly.

This shocking look made the face of Shunchao officials present very unnatural.

Liu Yu knew that if this continued, he would not finish talking about it the next morning, so he might as well get to the point.

"Mr. Piss, Mr. Huston, let's talk directly about you Westerners doing business with us Dashunchao. But I wonder if you can make the decision?"

Pis said proudly: "I'm not hiding it from the prince. In fact, this friend of mine, Haston, is my overseas duke of England. He has made great contributions to the British occupation of West India. He is our king, and he personally awards it. He can discuss anything about West India on behalf of the king."

After Pis finished speaking, the officials next to Liu Yu began to discuss, discussing where "West India" was, and why were they occupied by these Western devils? They also thought, since these Western devils had the tradition of invading others, why did they still have to do business with them?

Liu Yu didn't know whether the West India mentioned by Pis was an island on the Atlantic Ocean or India. Liu Yu guessed that it should be India, but because the Shunchao and the southern islands were located in the east of India, this part would be listed as East India. Liu Yu had known from Jason that the era of great navigation for the Westerners had arrived, and the great navigation was accompanied by invasion and immigration.

"The Duke of England? It's not simple." Liu Yu smiled, but in fact he was still thinking about it.

"I wonder what weapons did you use to conquer East India?" Liu Yu asked directly.

Piss looked at Huston in confusion, and Huston spoke, "We use long-cylinder artillery, a very powerful artillery, do you want it?"

Huston said excitedly and gestured with his hands, looking very confident and arrogant. This should be a kind of military arrogance.

The great voyage of Westerners, soldiers are merchants, and merchants take up weapons, that is, soldiers, and trade is accompanied by invasion. This Huston is just a hero for England to invade territory overseas. He may not be a noble in the country, so his way of speaking is closer to ordinary people in the city and has little cultivation.

"Does the Duke of Huston want to sell us artillery?" Liu Yu smiled, "If you have time, you really should have a good experience. I wonder if you brought artillery to Shunchao?"
