After making sure that all the books produced by the simulator were annotated, Lao Zhu bought Tiangong Kaiwu again.

After reading these two books, Lao Zhu gave these two books to Bi Maokang and Song Yingxing respectively.

The two of them are scientific researchers, so they can naturally see the value of this thing, and after reading it, the two of them are like treasures.

It's just that Lao Zhu's proposal to innovate the self-generated firearm and want to meet the level of the impact flintlock pistol mentioned in the annotation, the two said that they were a little difficult, but the problem was not very big.

Give them a month, and they can develop it, and at most two months, they can make it on a large scale.

Two months was still within Lao Zhu's tolerance, so he didn't rush the two of them anymore.

After all, the old man Bi Maokang is already seventy-one years old, and according to the trajectory of history, he has two years to live at most.

Although Lao Zhu specially sent him three imperial doctors to take turns to maintain Bi Maokang's body, Lao Zhu was not sure whether Bi Maokang could live for two more years.

So for this old man who was not in good health, Lao Zhu didn't even dare to say a heavy word, let alone urging.

And he also deliberately explained that if Bi Maokang had any ideas, he would try to let Song Yingxing do it.

And Song Yingxing is now in charge of not only the Ordnance Bureau, but also many things in the Ministry of Industry, he can also ask about them.

After all, Song Yingxing is only in his fifties, which is relatively much younger, so it is acceptable that the burden is a little heavier.

And Lao Zhu is not just squeezing the two, because the finances of the Ming Dynasty are now looser than before, so Lao Zhu not only gave enough funds to the Ordnance Bureau, but also directly expanded the Ordnance Bureau, recruited craftsmen from the people, and is expected to directly expand the Ordnance Bureau to 50,000 people.

Of course, 50,000 people is only the ultimate goal, and there is definitely no way to summon them all at once, but now it is just a slow summon, as long as it is a craftsman, the Ordnance Bureau will do it.

In addition, the yamen of the Ordnance Bureau was also divided into a large area by Lao Zhu, which was relatively remote, and Lao Zhu sent heavy troops to guard it, so that even if there was any big explosion, it would not affect the troublesome area.

……

Just when the reform in the capital was in full swing, Sun Chuanting, who was far away in Tongguan, Shaanxi, was not idle.

After this period of investigation of Li Zicheng, Sun Chuanting finally understood why the emperor told him that he didn't know much about the current Li Zicheng.

In the past, Li Zicheng had no attention, no discipline, and no decent equipment, and he was a complete rogue.

At that time, Li Zicheng only knew about burning, killing and looting, and after the army of the imperial court arrived, they immediately fled, ran to other places, and plundered again, which can be said to be a group of rabble.

It is precisely because of this that Sun Chuanting also dared to say that 5,000 elite soldiers were enough to destroy Li Zicheng, because they were not soldiers at all, but a group of bandits, and they had no combat effectiveness at all.

As long as Sun Chuanting seized the opportunity and fought head-on, it was enough to destroy them.

But now it's different, Li Zicheng has become a climate, and his wings are full.

Now Li Zicheng, after defeating Fu Zonglong, collected tens of thousands of elite Qin soldiers in Shaanxi, and also harvested nearly 20,000 baggage, in addition, in large and small battles, he also incorporated many generals of the Ming army, expanding the strength of the army.

It can be said unceremoniously that Li Zicheng's army is now qualified to compete with the main force of the Ming Dynasty.

But the main force here refers to the elite army of the Nine Sides, and the combat power of these recruits in Sun Chuanting's hands is not as good as Li Zicheng's army at all.

And the most important thing is that Li Zicheng now has an additional strategist Li Yan under his subordinates, this person was originally a man from Kaifeng, who was both civil and military, but later because he was completely desperate for the corrupt and dark Ming, so he directly voted for Li Zicheng.

For Li Zicheng, Li Yan is definitely his nobleman.

Li Yan not only compiled the ballad of Yingchuang Wang Buliang that spread all over the world, which won a large number of people's hearts, but also proposed the strategy of exempting Juntian from taxation, which attracted a large number of displaced people to join Li Zicheng.

The reason why Li Zicheng was able to make such a big noise this time was definitely due to Li Yan's contributions.

If it's just like this, it would be okay, but what made Sun Chuanting feel most troublesome was that Li Yan persuaded Li Zicheng to restrain his soldiers and stop burning, killing and looting, which greatly strengthened Li Zicheng's military discipline and made Li Zicheng's army completely evolve from a rogue army to a regular army.

"No wonder Your Majesty is so cautious."

Sun Chuanting rubbed his eyebrows with a little headache, the current Li Zicheng is really difficult to deal with, and he has to think in the long run.

Of course, taking a long-term view does not mean that he will definitely follow Hou Xun's strategy of pacifying the thief.

Because Hou Sui's strategy of leveling thieves is completely based on sacrificing the people of Henan, after all, no matter how good the military discipline of the thieves is, they are also thieves, and when Li Zicheng has been besieged for a long time and falls into a situation of no food, Li Zicheng will definitely not care about any military discipline.

At that time, Li Zicheng's army, which was huge, would completely turn into the most ferocious rogues and plunder Henan.

What's more, Li Ziwei was born in a rogue, and what he is best at is escaping, and Hou Sui wants to completely surround him to death in Henan, which is not easy to say.

Therefore, Sun Chuanting did not approve of this decision from the beginning, and it was only because the current Ming could not afford the loss that he was persuaded by the emperor and finally agreed to this decision.

However, before he came to Shaanxi, Lao Zhu had explained to him and gave him the right to make decisions on the spot, which means that if he felt sure, he could take the initiative to attack, and he didn't have to wait for the order of the imperial court at all.

Therefore, Sun Chuanting's current idea is that before training the recruits, he will not move the troops for the time being, and after he is sure of it, he will no longer care about Hou Sui's strategy of leveling the thief, and will have a direct decisive battle with Li Zicheng.

After all, although Li Zicheng is a regular army, he does not have any outstanding generals under his command, if the strength is about the same, Sun Chuanting has enough confidence to crush Li Zicheng.

Thinking of the training, Sun Chuanting's face once again showed a trace of helplessness, Lao Zhu basically didn't give him any salary, the little salary allocated to him by the household department, in order to recruit new soldiers, he had basically used it, so now he has to find a way to get food and salary first.

Otherwise, let alone training, it would be strange if his soldiers didn't finish running.

Sun Chuanting turned his head to look at Gao Yushun, the overseer sent by Lao Zhu, and asked, "Gonggong Gao, I don't know the military field that was invaded in Tongguan, can you find it out?" ”

"Nope."

Gao Yushun shook his head lightly and said, "Tian Shu was set on fire, and now nothing can be found out. ”

"And if the land is cleared, it will take too much time, and I'm afraid the superintendent won't have the time to wait."

"Tian Ce was burned?"

Sun Chuanting frowned and looked at Gao Yushun, and said in a somewhat puzzled tone: "With the skills of the Jinyi Guard under Gonggong Gao, how could this happen?" ”

Gao Yushun heard the doubts in Sun Chuanting's tone, and he didn't mean to be angry at all, but continued to speak in a soft voice:

fo

"It's not that Jinyiwei is ineffective, but that there are internal ghosts."
