?A muffled sound came from a small courtyard in some of the courtyards outside Bazhou, and then a wisp of black smoke rose, as if a monk had failed to ascend in the sun.

"Ahem cough cough"

Several people wearing strange clothes and ferocious faces rushed out of the door and were breathing outside the yard. Several people were extinguishing the fire. Fires were lit on a stove in the yard, and black smoke was emitted from several jars and jars.

Yuwen Wen pulled down his mask and asked the person next to him with a dark face: "Master Liu! Have you added something wrong?"

The man took off his mask and muttered to himself in confusion: "No... I'm just a little..."

"Slightly? Master Liu, this is not a joke! If I hadn't been wearing a mask just now, I would have been covered in a look!"

"Stop your anger, everything is in control..."

Looking at the few sticky objects that were steaming on his mask, Yu Wenwen rubbed his temples. If he hadn't been wearing a mask just now, he would have been really dark: not only was he bad luck, but he was also disfigured.

However, for Huang Chengcheng's gold, he decided not to have the same knowledge as Liu Yang. Of course, it was actually brass, but based on some needs, he could use it as gold without his conscience.

"The Lord, the fire has been put out."

"Very good, record the details of this experiment and find the reasons."

Yuwen took off his white coat,

This was what he equipped the workshop experimental staff based on "advanced experience" and a mask with simple glass goggles to avoid accidents in the experiment and endangering personal safety.

Glass goggles are easily cracked by external impact, and glass residue can also damage the eyes, but at least it can prevent all kinds of reagents from sputtering to damage the eyes. The two harms are taken lightly. Yuwen Wen can use the civil method to ensure the safety of the experiment.

As a result, Liu Yang, the "Danye Light Demon", became more and more fearless and frantically conducted experiments. After coming to Bazhou, this person was shocked by various glass test vessels in the workshop and watched Lin Youdi's chemistry experiment demonstration, which instantly rejuvenated for a second spring.

Liu Yang, who has been practicing alchemy for decades, found that he was like a frog in the well. He finally came to the world outside the well and felt that he had lived in vain before and had to make up for it twice as much as possible.

"Mr., there are three minutes left...it's almost the time."

Liu Yang looked at the wall clock and found that this was a good thing, with the time accurate to minutes. Although it was easy to break, it was very useful for experiments. There was no need to rely on hourglass or leaky pots to time as before.

The group moved into the next courtyard. Several stoves were lined up in the courtyard, and several rows of clay cans were "inserted" on it. What we are doing now is to perform the "spotting of gold" offered by Liu Yang, and the key to the trick is in this clay can.

At this time, the fire in the stove had been extinguished. Several people carefully took out the clay pots with iron tongs. The clay pots were conical like bamboo shoots, with one end flat and the other pointed. When the clay pots cooled, they broke the flat bottom and one end could get something from the small clay pocket.

In the Ming Dynasty, it was called Japanese lead, which is metal zinc. With the smelting technology of this era, zinc could not be obtained stably. However, the alchemy Taoist Liu Yang found a trick, which was the special structure of clay pots.

Liu Yang couldn't explain the principle. Anyway, he knew that this could refine magical things and turn them into yellow gold after being refined with copper. Yuwen Wen knew that this was actually brass.

"Master Liu, see how they practiced?"

"Yes, this clay pot is much more refined and the time is short, and the chance of refining is significantly higher than before."

"There is land, it's done well."

Yuwen Wen was very satisfied. Today, Lin Youdi led the craftsmen to perform the entire process of "slicing gold" reduction, in order to master the method of smelting zinc. As long as there is zinc, it will be much easier to make brass.

The gold-spotting technique presented by Liu Yang needs to be standardized and parameterized, and understand various reaction conditions and processes, and then mass-produced "gold". Lin Youdi and others are now exploring, and according to the current situation, the progress is smooth.

The problem is that zinc smelting raw materials are the biggest problem. This raw material mineral is called "calamine". Yuwen Wen is not very clear about the correct chemical name. Although it can be found in the southern part of Shannan, it is not much.

Yuwen Wen was not sure whether there was a "calamine mine" in Shannan Prefecture County. After all, this thing is not used on weekdays, so if you want to mass-produce "gold", there are still many problems that need to be solved.

What should I do if I can’t find the “calamine mine”? It doesn’t matter, if I have more skills, I won’t suppress myself. With zinc smelting, sooner or later, Yuwen Wen will become the King of Gold (pseudo).

"Langjun, this clock is very useful, but it's too easy to break."

"It's still being improved, and it may take several years to be useful."

"This thing is quite exquisite. Is the armillary sphere that Assistant Professor Liu is currently producing? Is it a reference to the principle of the clock?"

"However, the different clocks and armillary spheres are, the smaller the better, so the structure is so sophisticated and easy to deteriorate. Now the clock production process and structure are still being explored, so it is impossible to be anxious."

"Langjun, is the material used for the thermometer glass?"

"Strictly speaking, it should be glass. The prism used by Master Liu's modified spectrometer is also made of glass."

The two were talking, and at this moment, the bell suddenly rang out. It was the bell that "get off work", just about noon.

Yuwen Wen began to promote clocks in workshops and mansions. Although the failure rate is extremely high, he still persists. In the first place, it is used as a trial operation to facilitate finding various fault points of the clock and improve it.

The second is to instill the concept of "punctuality".

Only when the timing tools that are accurate to the minutes appear can punctual become meaningful, and the emergence of practical clocks and watches can provide strong support for the development of technology.

Yuwen Wen is not going to develop black technology, but to prepare for the upcoming needs.

There is a kitchen in the workshop,

For the people living and working here, Yu Wen Wen, who inspected the workshop, dined in the kitchen and answered the endless questions of "question baby" Liu Yang.

Just after halfway through the meal, someone from the mansion said there was urgent news.

......

Suizhou, Suicheng, and the headquarters of the big street.

"Yang Ni is eyeing him, Yuchi's right is in great difficulty, the Great Zhou Dynasty is as dangerous as eggs, and the country is surrounded by tigers and wolves, and only the royal family can rely on. I want to reorganize the country, and I hope Qi Gongliang, Prince Ming, and Xiyang Gongwen will work together to help me support the country."

After reading it, Yu Wenliang's expression was solemn. This was the content of his son Yu Wen Wen's retelling. The person who wrote this content was the current Zhou Emperor Yu Wen Qiankeng.

"Your Majesty is early wisdom, it is a great blessing for Yuwen..."

"Father, Your Majesty's heart is like a mirror, but now it is not the time. Yang Jian is eyeing him, and the Great Zhou must not be in chaos."

"For the Father, I know."

Yuwen Liang nodded. Now is not the time. There are tigers outside. If there are internal strife in Zhou, it would be a death sentence, but the preparations that should be made cannot be relaxed.

"Father, what happened to the war in Jingzhou?"

"The stalemate cannot be stopped, Shangwan is not something that the Sui army can chew."

"Father, has our army used thunder bombing on the Sui army since the invasion of Shannan?"

Yuwen Liang shook his head and showed a firm look on his face: "No, even if Shangwan is lost or Rangcheng is lost, it will not be used!"

"That's fine. It's easy to survive for two years, and I have to continue."

What Yuwen Wen said seemed a bit inexplicable. The father and son did not continue to discuss this topic. Yuwen Liang recruited the second son and there were still many things to ask. The eldest son Yu Wenming now led the Xiangzhou army to resist the attack of the Sui army on the West Road, and failed to get out of Suicheng, so the father and son met.

First of all, Yuwen Wen answered all the things that happened during his time in Yecheng. Of course, some details were "slightly" concealed. Anyway, he had to come back all the time, so there was no need to worry about anything.

Yuwen Wen promoted the Duke of Zhu to the position of Duke of Zhu as a father, and Yuwen Liang was naturally relieved for his son to go further.

But Yuwen Liang was also worried that Yuwen Wen had a sudden idea and took the risk of returning from the sea. He was also whispered to Japan to "travel here". This kind of thing was too incredible. He was not sure whether Yuwen Wen was telling the truth or lies.

But what is even more incredible is that the thirty ships of salt were transported from Jiankang, and Yuwen Liang had serious doubts about his origin.

"How did you get this salt?"

"My son met Chen Shubao, the emperor of Chen State, in Jiankang. He had a great time talking. After his permission, he bought thirty ships of salt and came back."

Yuwen Wen directly told the answer. Such frankness was beyond Yuwen Liang's expectations. He stayed for a while, trying to say something but couldn't say it.

Thirty ships of salt have greatly alleviated the crisis that Shannan is about to face. After the fall of Hezhou, the contact between Shannan prefectures and the court was interrupted. One of the most direct effects was salt shortage.

Shannan does not produce salt, so it is necessary to transport salt from other places. Although it is not short of it immediately, it is not a big deal over time. The thirty ships of salt that Yuwen Wen brought to make Yuwen Liang breathe a sigh of relief.

If you last for a few more months, you can hold on until the road is opened!

Yuwen Liang was very satisfied with his son's "gift", but now he was a big surprise: he actually had a great conversation with Chen Shubao, the emperor of Chen State!

"Father, my son was a pseudonym at that time, so Chen Shubao didn't notice it." Yuwen Wen knew what his father wanted to say, "Chen Shubao indulged in alcohol and sex, drank and had fun every day and ignored the government. Now he is the best seat for Chen Guoyu."

"Yes, yes, it's the most suitable for him to be this emperor!"

Yuwen Liang twisted his beard and said, Yuwen Wen was right. If Chen Shubao was killed, the newly ascended Emperor Chen would have to worry about it, so it would be reassuring to be the emperor.

Since Yuwen Wen went to Yecheng, he has been terrifying news from time to time. Now, Yuwen Liang has heard his son say the details and finally got to know the summary of the matter. Finally, he feels relieved. After finishing his "business" and starts to talk about some family matters.

"After that incident last November, your wife had already sent a letter to tell her the whole story of her father. There is nothing wrong in the house, so don't believe the rumors spreading outside."

"My son knew that when he heard rumors at Jiankang tea shop, he almost believed it."

"It is not easy for a man to handle it at home, and it cannot be done for a second time!"

Yuwen Wen nodded. Of course, this kind of thing cannot be allowed to happen again. The fake product was at least to "rescue" Yang Lihua, so as not to cause trouble to his wives and concubines. If the next time a flower picker came, he would not be so lucky.

While he was talking, a postman brought an urgent report. Yu Wenliang looked carefully and breathed a sigh of relief. He immediately handed the letter to Yu Wenwen: "You can take a look at it yourself. The court has taken down Guangcheng in Guangzhou."

"Have you taken down the city of light?"

Yuwen Wen took the letter and looked happy first, then his expression became complicated.

"It turned out that I used the sky-booming thunder to blow up the city wall..."

Yuwen Liang nodded: "In this way, the official road from Guangzhou on the northern foot of the Dabie Mountains to the southern foot of the southern foot of Dingzhou on the southern foot of the Dabie Mountains will be opened soon."

"The government army breaks through Guangcheng, so the Yuzhou General Administration of Sui State will definitely not be able to sit still. The government army will definitely attack the Xuanhu, the general administration office of the General Administration. With the powerful sky-blasting thunder, the Sui army will not dare to entrust. The army attacking Shannan will inevitably withdraw to Yuzhou!"

"So Shannan finally got through it!"

Yuwen Wen agreed with this inference, but he was thinking about another thing: the connection between Shannan and the court was connected again. Although it had changed a path, it was now going straight and the distance was closer.

So? If I didn't leave at that time, I stayed in Yecheng for a few months to eat, drink, gamble, and have fun, and now I can come back with a big swagger. Why bother to go on the sea road and almost bury myself in the belly of a fish?
