Bi Sheng's movable type printing has basically reached the practicality, especially the newly produced pottery movable type is more durable than the wooden movable type, which is Bi Sheng's most proud invention, but Bi Sheng is also very distressed about the shortcomings of the pottery movable type.

When the clay is fired, the original engraved words are easy to deform, so burn more than a dozen words, there may not be a satisfactory one, so the strokes can not be too fine when carving on the clay, so that the pottery movable type can not be printed with small characters.

Li Buqi asked why he didn't use iron, copper, or lead as movable type, so that the new movable type only needs to be remolded, and the font can be made relatively small. Bi Sheng replied that metal materials do not stick to ink.

Li Buqi suddenly realized. The ink of this era was diluted with water, and the surface tension of the water was too great, and it did not infiltrate the metal surface, so ink was used in later printing. Li Buqi was engaged in chemistry before crossing, and there are still some ways to reduce surface tension. So he explained to Shao Yong and Bi Sheng, the mountain chiefs of the academy, that they wanted to make three sets of movable type pottery movable type for printing advertisements and revealing posts, which needed to use large characters, wooden movable type for printing books and leaflets, and lead movable type for experimenting with ink.

Movable type printing is a matter of merit, and Li Buqi asked the academy to give full support, in addition to immediately recruiting some craftsmen, but also recruiting a group of scholars to work and study to set up a printing workshop.

In addition, Li Buqi also contributed a font that was once called "imitation Song style", and put forward several suggestions for the "word inspection plate" invented by Bi Sheng.

From Zhe Yinghui, Li Buqi didn't ask anything valuable, so he felt very wrong about the sluggishness of the Zhe family. It's just that Zhe Yinghui can't make a big noise about the matter of hiding in Tokyo, so he has to go back to the city with a lawsuit.

Zhou Qing's deputy sent someone to escort the goods back, and he brought several good news and one bad news.

The good news is that they also found ginseng in Goryeo and bought a batch from the Koreans. Moreover, the Jurchens who traded with them on the coast of Liaodong this time were a large tribe, and the goods were far more abundant than those small tribes in the past, not only did they have more ginseng, but they could also take out tiger skins, turquoise and eastern pearls, so they not only brought back ginseng and furs and other goods this time, but also increased the two goods of gems and pearls.

Judging from the inquiry, the small Jurchen tribes that originally traded with them had been swallowed up by the nearby large tribes, and the larger tribes controlled the trade in place of these small tribes. This situation is well understood, and it is strange that the small tribes that have profited from trade have rapidly increased their wealth but do not have enough strength to protect themselves.

What happens when the wealth of the Great Tribe increases? It's definitely going to continue to annex the small tribes around it to increase its strength. When the strength increased to a certain extent, it was time to cause trouble for the Liao State, and Li Buqi sold them a lot of iron weapons. Although those iron arrowheads and steel knives were inferior goods that the Great Song army looked down on, in the eyes of the Jurchens, who did not have many iron tools available in the past, they were like big killers, and I believe that they would definitely be emboldened.

From this incident, it can be seen that the trade of a few ships every year will set off a big storm in Liaodong. Li Buqi couldn't help but admire himself from the bottom of his heart.

When they passed through Tsushima Island, the Japanese took out Japanese swords, gold and silver, and Japanese iron, sulfur, and iron pear wood in exchange for silk, porcelain, glass, and books, because most of the goods loaded on the ship were iron and linen suitable for Liaodong, so the Japanese asked to bring more goods they needed to trade next time. Judging from the fact that the Japanese people of Tsushima were able to come up with more and more gold and silver each time, the voice of Japan was still worth doing.

The bad news was that the three ships were blown north of Tsushima Island by a strong wind and tsunami on their way back, and had to enter a large harbor off the coast of Ulju, Goryeo, to take refuge from the wind and come into contact with the Koreans. There were officials nearby, and when the Koreans saw that they were foreigners, they tried to detain them, but fortunately they ran fast and ran away before the Korean brigade arrived.

Walking by the river is often impossible without getting your shoes wet. The route is along the coastline of the Korean Peninsula, and it is common knowledge to take shelter from the coast in bad weather at sea, and this situation has long been expected by Li Buqi. Therefore, Li Buqi only replied with a letter, asking him to strengthen the construction of Tamna Island according to the originally agreed plan. There are already more than 500 Song families on Tamna Island, and 20 Mongolian horses have been transported for breeding this year, which should be able to play a role.

This time, because the relatively large Jurchen tribe participated in the transaction, the tendons, horns, and feathers were nearly twice as many as in the first half of the year. Li Bu gave up selling these things to the third division, making a lot of money, and he could also help the case solve the problem of shortage of raw materials. It's just that he didn't expect that in a few days, this would also become one of his crimes.

Cheng Jun quietly went into Li Buqi's official room to report that everything was arranged, and asked Li Buqi to hand over the paperwork for the purchase of a lathe, hinting that Li Buqi would take advantage of the chaos and never suffer in the future.

Li Buqi was a little surprised by Cheng Jun's efficiency, and confirmed: "Can you really never suffer in the future?" ”

Cheng Jun said confidently: "Judge Li rest assured, this time let those who intend to frame officials learn a lesson, and they must be calm for three or five years." Who will go over the old accounts in the future? ”

Hearing this, Cheng Jun and his gang made up their minds to use Li Buqi as a shield. In this regard, although Li Buqi was disgusted, he was helpless. If you want to shoot these little moths to death, then there will be no one to work, and it will only make people laugh. So for the sake of political performance, I have to tolerate them.

Li Buqi asked someone to ask Liu Xiang, the deputy envoy of Yantie, who happened to be in the Third Division, so he picked up the application and went to Liu Xiang in person. Liu Xiang was silent on the surface, but his suddenly shining eyes had actually betrayed him.

After the ecstasy, he read the document from front to back again, and made sure that he was not mistaken, and couldn't help but secretly scream in his heart: Li Bu give up, Li Bu Qu, Wang, you are so careful and so shrewd, how could you send such a big handle to the old man, this time it will definitely make you ruined, and you will never be able to turn over again.

As soon as he looked up, he remembered that Li Buqi was still sitting next to him waiting for a reply, and he pretended to put Li Buqi's documents on the case casually: "Li Judgment, this matter costs a lot, and you need to be cautious." I will reply to you after I have consulted the minister and the deputy envoy. ”

Li Buqi didn't dare to slack off when he saw the light in Liu Xiang's eyes, said goodbye, and went back to the office to take out a bunch of paperwork written in the past few days.

At the same time, the two Xiang troops who were arranged by Li Buqi to secretly pay attention to Liu Xiang's movements kept sending back news. Liu Xiang first found several officials who had been dismissed from the case by Li Buqi and closed the door, and he didn't know what to say, and after these officials left, about two meals later, Liu Xiang hurried to the Yushitai.

Sure enough, before evening, news came out from the Yushitai and Tongjin Yintai Division: Yushi Liu Xiang impeached Li Buqi for three major crimes of corruption and several minor crimes. This news immediately detonated the circle in Tokyo, and the imperial historians followed up to impeach Li Buqi, which was also a special honor for a small judge of the third division.
