After the return of the army, Zhu Yuanzhang soon began to prepare for the next northern expedition.

This time due to the accident caused by Chang Mao's recklessness, the northern expedition failed to do its best, and now the Northern Yuan is still in a state of scattered sand, if someone gathers these stragglers in the future, it is a big threat to the Ming Dynasty, and he is old at this time, and he is in a hurry to get rid of this Ming henchman.

There are not a few people in the court who understand this truth, and they are also discussing the matter of another northern expedition in private, but at this time, Guangxi and Yunnan and other places suddenly reported to the imperial court that there was a rebellion in the Northern Yuan Dynasty and the Tusi Rebellion.

Although Mu Ying was stationed in Yunnan, Zhu Yuanzhang was still not at ease, so he transferred Fu Youde to quell the rebellion together.

Originally, Fu Youde was the main general of the expedition to Yunnan, and it was most suitable for him to go.

As for the matter of conquering the north, there is also Feng Sheng.

After Fu Youde left, Zhu Yuanzhang also officially ordered another northern expedition.

However, at this time, there were illegal acts in the court that impeached Feng Sheng for secretly hiding good horses and forcibly seizing wives during the Northern Expedition.

Chang Mao, who was imprisoned, also began to attack Feng Sheng's various illegal acts, and even deducted the reason for the enemy's rebellion on his head.

When Zhu Yuanzhang saw these impeachment notes, he was immediately furious and ordered Feng Shengqi to live in Fengyang's hometown and not be allowed to go out, and at the same time withdrew the reward given to him.

In the Ordnance Bureau, Li Wei quietly listened to Chen Su's report.

In order to avoid Zhu Biao, and for the sake of safety, he moved to the Ordnance Bureau again.

After Chen Su finished saying these things, Li Wei pondered for a moment, and suddenly showed a smile: "Interesting." ”

These things made him feel familiar, just like those things arranged by Chen Su when he went out to conquer the Wa Kingdom.

At that time, in order to win military power for him, Chen Su and his courtiers prepared to impeach Tang He, although he was finally suppressed, but the result did not change much, Tang He was still recalled due to negligence, and he successfully obtained the command of the Japanese army.

Now the imperial court is preparing to march north again, but several generals who led the troops, first Fu Youde was transferred away due to the rebellion in Yunnan, and then Feng Sheng was impeached and convicted, which is obviously someone repeating his original deeds.

"Master Hou is wise, and his subordinates also think these things are unusual." Chen Su said in a deep voice.

Those things were originally planned by him, and although the methods of these people are different now, it is impossible to hide them from him.

Li Wei bowed his head lightly and ordered: "In this way, you go to investigate to see who is secretly instigating this matter, and keep an eye on Lan Yu's side." ”

Now Feng Sheng and Fu Youde can't participate in the Northern Expedition, Xu Da is unwell, and the remaining generals in the court who are qualified to lead the troops, except for him, the Duke of Hanguo, only Lan Yu is barely enough.

Of course, he knew that it was impossible for Zhu Yuanzhang to let him lead the troops to the expedition again, otherwise the series of arrangements for the transfer of the Shenji Battalion and the Sailor Division would be in vain, and then the only remaining people who led the troops would be Lan Yu.

"Yes!"

Chen Su said yes, then turned around and left, following Li Wei's instructions to investigate these things, and staring at the movements in the Blue Jade Mansion.

At the same time, Jin Yiwei is also secretly investigating these things.

With Zhu Yuanzhang's astuteness, he naturally wouldn't be unaware of the strangeness of these things, but he still severely reprimanded Feng Sheng and drove him back to his hometown.

Feng Sheng is also a veteran, but he is not as knowledgeable as Tang He and Li Shanchang, and now several of the founding princes, Xu Da is ill and no longer cares about military politics, Tang He and Li Shanchang also resigned after Li Wei became a prince, leaving him a founding prince in the court, Zhu Yuanzhang was also a little unhappy with him, and he just took this opportunity to drive him back to his hometown directly.

As for the Northern Expedition, it naturally fell on Lan Yu.

As Li Wei thought, it was impossible for him to hand over this matter to Li Wei again, after all, although Lan Yu was in high spirits now, he was still a little worse than Li Wei, so he naturally wanted to help Lan Yu suppress Li Wei.

Under the leadership of Mao Xiang, Jin Yiwei secretly launched an investigation into Lan Yu and Li Wei.

Although Zhu Yuanzhang will not hand over the matter of the Northern Expedition to Li Wei, judging from the current situation, Li Wei is also one of the candidates for the leader of the Northern Expedition, so it is not ruled out that Li Wei may manipulate everything.

Jinyi Wei has a large number of people, and his ability naturally has nothing to say, and Mao Xiao soon found Wang Xing beside Lan Yu.

Originally, there was an extra Confucian in the Blue Jade Mansion, which was nothing, but this Confucian had also stayed in Li Shanchang's Mansion, so it was a little different.

Although it was not certain whether these things were related to Wang Xing, Mao Xiang still reported the matter to Zhu Yuanzhang.

In the Qianqing Palace, Zhu Yuanzhang listened to Mao Xiang's report, and his eyes narrowed slightly.

"Your Majesty, do you want to arrest and interrogate this king?" Mao Xiang asked tentatively.

However, Zhu Yuanzhang shook his head lightly: "No, let this go in advance." ”

Even if it was true that these things were manipulated by Lan Yu and the people behind his back, he didn't want to touch Lan Yu for the time being.

He wanted to see what surprises these people could bring him by pushing Lan Yu up.

At the beginning, Li Wei made a pass, but in the end he made a contribution to destroying the country, if this blue jade could be led and destroyed the Northern Yuan to him, then he would be too happy to count, and naturally he would not stop it.

"Is there any change over there Li Wei?" Zhu Yuanzhang asked instead.

"Back to Your Majesty, I haven't found any changes in the Duke of Han." Mao Xiang replied respectfully.

Zhu Yuanzhang frowned slightly, he always felt that this kid would not be honest, since that time this stinky boy in the court put on a majestic show, he has made repeated moves and replaced the slaves in the family, but now he is honest again, which is really unusual.

After thinking about it, Zhu Yuanzhang put his affairs aside first, and instructed Mao Xiang: "Okay, we know, you continue to stare at it, don't startle the snake on Lan Yu's side, we have our own arrangements." ”

"Yes."

Mao Xiaogong claimed that it was, and then Zhu Yuanzhang asked him to step down.

A few days later, Zhu Yuanzhang officially issued the will of the Northern Expedition, with Lan Yu as the general, Tang Shengzong and Wang Bi as his deputy generals, and Sun Ke, Guo Ying and others as generals, and launched a conquest against the Northern Yuan again.

Li Wei also learned about Wang Xing through Chen Su's investigation, and was not surprised by Zhu Yuanzhang's decision, but he didn't care too much, but focused on Minghuang Academy.

After he gave Tao Sheng some ideas, all the last technical difficulties of the new college were solved, and this nearly modern college was finally completed.

On the day of the opening ceremony, Zhu Biao was present in person, and Li Wei and Fang Xiaoru co-presided over it.

Zhu Biao and Fang Xiaoru were amazed when they saw the faucets that could be turned on and the lights that could be turned on with the push of a switch.

Li Wei laughed at them that they had never seen the world, and at the same time, he secretly sighed in his heart.

He has also been using these things for a long time, and now it has been eight or nine years before he uses them again.

After the opening ceremony, Li Wei began to enroll.

When he was in Xiaopo Courtyard before, Minghuang Academy had accepted a total of more than one hundred and more students, plus those inmates who followed Fang Xiaoru to the academy, there were only two or three hundred people in total, but now with this huge new academy, he can finally standardize the enrollment of students.

As for the teachers, it is natural that these newly graduated students are filled, and those who failed at the beginning have agreed to stay in the academy to teach, while other people such as Zheng Zhihua and Lu Xiu, who have become officials, can also come to the academy to teach part-time when they have time.

There are also Tao Sheng and others who stayed in the Ordnance Bureau, and when they are not busy, Li Wei will also let them come to the academy to work as teachers.

In short, this time he doesn't have to teach by himself, he can recruit more students.

Due to the turmoil of "the gentry receive food in one", no one among the current literati is willing to come to his Minghuang Academy, including those who previously agreed with Minghuang Physicism, and most of them have drawn a clear line with the academy.

But it doesn't matter, Li Wei didn't really think of them as students of the academy in the first place.

In this recruitment, he mainly recruited the children of those craftsmen of the Ordnance Bureau, and some of them were the children of sailors and soldiers of the Shenji Battalion.

Most of these children are from poor backgrounds and cannot afford to go to school at all, and the academy provides free teaching and food and lodging, so they are naturally very happy about such a good thing.

As for the "gentry receiving food in one body", it has nothing to do with them.

Within a few days, the newly established Minghuang Academy enrolled thousands of half-year-old children, fortunately, there were students who had just graduated from Hou Jun and Song Baozhong to teach, and they helped to take care of these children, otherwise he would definitely not be able to take care of them.

After settling down these children's classrooms and dormitories, he improved them according to the lessons taught in Xiaopo Courtyard before, and let Hou Jun, Song Baozhong and others teach in this way.

Of course, Fang Xiaoru still taught him Ming and Huang science, although Li Wei didn't care about this, but he attached great importance to it.

When Li Wei was busy with the affairs of the academy, the army of the Northern Expedition also went out, and Lan Yu led the army to arrive in Gyeongju, which had been occupied by the Ming army.

It's just that this place is far away, and the environment along the way is harsh, even if he is well prepared, it is still difficult.

Fortunately, there were many generals in the army who surrendered from the Northern Yuan, who had lived in the grassland for many years and were familiar with these terrains, and played a leading role for the Ming army, which led the army to this destination smoothly.

The Great Khan of the Northern Yuan Dynasty, who was hiding in the fishing sea, did not expect that the Ming army could find this place, after all, this place was already very far north, and it was impossible for the Ming army to find it if they were not familiar with the terrain.

However, the Northern Yuan Dynasty was in extreme decline at this time, not only did there be countless surrenderers, but there were also spies within his Yuan court who betrayed his position.

Lan Yu sent Wang Bi as the vanguard to raid the Yuan army, the Yuan army was killed unprepared, although the 100,000 Janissaries guarding the Northern Yuan Dynasty tried their best to resist, but they were not the opponents of the Ming army, the generals of the army were killed, and the rest of the 100,000 troops were captured except for those who fled.

The crown prince and princess, the royal concubines of the Northern Yuan, could not escape, and could only escape with dozens of fast horses, but he had also become the Emperor of the Cursor, and he did not run long before he was killed by the descendants of the hostile Ali Buge, and the Northern Yuan completely collapsed and collapsed since then.

When the news came back to Jingshi, Zhu Yuanzhang was overjoyed, this Qianyuan, who had been remembered for more than 20 years, finally completely collapsed in his lifetime, and it was also a knot in his heart.

Lan Yu made great contributions this time, and Zhu Yuanzhang did not wait for Dabian to return, so he had already drawn up the will for him to be canonized.

Li Wei also got the news, he was not surprised that Lan Yu could achieve this kind of big victory this time, one is that he had already known that Lan Yu would have such a great achievement, although he was not sure when, but it was a matter of time.

Moreover, Wang Xing's existence also vaguely indicates that someone secretly helped him ascend to the throne, and it is not surprising that he can achieve this feat.

However, he remembered that after Lan Yu was crowned the duke, Zhu Yuanzhang was about to go on a killing spree, which made him feel a sense of urgency.

He didn't know that he was not on Zhu Yuanzhang's must-kill list, but judging from the current situation, I am afraid that the possibility of him being on the list is also very great.

Daming's technology has developed to this day, to be honest, it is enough, and he has already built the academy, the knowledge has spread, and his uniqueness has slowly decreased in the future.

As long as the imperial court continues to support the academy in cultivating scientific and technological talents, the development of science and technology in the future will be inevitable, and it will not make much difference whether there is him or not.

Fortunately, now the academy and students are still in his hands, and even if Zhu Biao has repeatedly shown kindness, he cannot replace his position.

The day after the news of the great victory in fishing came back, Li Wei went to the Ordnance Bureau.

In the Ordnance Bureau, the special steel pipes made by Tao Sheng were cut into two specifications of different lengths by him, about half a meter long and more than 20 centimeters short, and at the same time asked Tao Sheng to take people to secretly engrave rifling on these pipes.

To this extent, Tao Sheng also knew the purpose of these steel pipes, since he wanted to engrave rifling, it was naturally used as a barrel, but he didn't know what these new muskets that the teacher was going to do would look like.

In addition to these steel pipes, there are many scattered parts, especially springs and the like, which are very important, Li Wei personally inspected them and sampled some of them.

Now that the Ordnance Bureau has been transformed, it has basically achieved standardized production, and the quality of these things produced is not much different.

"By the way, how are the three acids produced?"

After inspecting these spare parts, Li Wei asked Tao Sheng again.

These parts were all designed by him to make the real firearms of later generations, but these alone are useless, the most important thing is smokeless gunpowder and firing charge, and if you want to make this kind of thing, the chemically basic acid and base is the most important.

Tao Sheng immediately replied when he heard this: "Those have already produced a lot, and they are all strictly kept in the Ordnance Bureau according to the teacher's requirements, and they are guarded by special personnel. ”

"Well, that's good." Li Wei nodded, and said, "By the way, in the end, buy more cotton, I will be useful." ”

Now that the acid and base are available, it is time to try to make smokeless gunpowder and firing charges.

Tao nodded yes, this matter is not difficult, the Ordnance Bureau usually has to purchase a lot of cotton for papermaking and the like, and purchasing more will not attract attention.

The things in the Ordnance Bureau were properly arranged, and Li Wei was a little relieved.

As long as he has these weapons, even if it is only three thousand guards in his hands, it is enough to deal with contingencies, and it is really too late to temporarily expand the army, as long as there are these weapons, even if he pulls a group of children, he can slaughter the army dominated by ordinary cold weapons, not to mention that so many craftsmen in the Ordnance Bureau are available, they are still very familiar with firearms.

Moreover, although his sailors were transferred to Beiping, if it was really necessary, it was not impossible to transfer, but it would just take some time.

With so much power in hand, as long as the guns are made, there is nothing to fear about any blue jade and the like. (End of chapter)
