If you don't leave, that's a good thing, but if you leave......

Then what he promised Qin He could not be completed.

He wasn't worried that on the premise of knowing the truth, Qin He would have some misunderstanding with him because of this matter.

What he worries about is that he carries the black pot for others.

After all, something like that happened in the agreed place between him and Qin He.

If you want to explain it when you want to do it, you may not be able to explain it clearly.

Now that he wants to become the head of the Xie family, then he will inevitably need Qin He's help.

Without Qin He's help, it would be equally difficult for him to become a member of the Xie family.

……

Qinghe Prefecture, Dongqin Island.

Today's Qin He doesn't know what happened to Liu Qiang now, let alone that someone has died because of this.

For Qin He today, what he is most concerned about is the busy farming in the early spring.

Although he has already taught a lot about the cultivation techniques.

However, in many places, due to the different soil quality, the cultivation method is also different in many cases.

For this reason, the Qin River has been running almost throughout the province during these times.

Depending on the soil in different places, it is decided what kind of cultivation method to use.

Of course, because there is no such advanced soil testing technology in this era.

Therefore, Qin He can only start trying every place he goes.

Through different attempts, combined with the agricultural knowledge that I don't know much about, I experimented.

Fortunately, all but the saline soil has found a suitable planting method.

In this way, it can be regarded as a major solution to the major problem of spring sowing.

After all, for them, the big problem of food has to be solved.

After finishing this wave, Qin He rushed to the previously discovered mine non-stop.

Originally, he didn't need to worry about this matter, but because the alchemy technology of this era was really not very good.

Qin He naturally didn't intend to ignore it.

After all, this is a matter of life and death for his subordinates, and Qin He doesn't want to be sloppy.

The guy in hand is better than the others, so when the battle is really fought, he will be able to have an advantage.

On the battlefield, even a slight advantage can be the key to victory.

After Qin He's guidance, the weapons refined were obviously much better than before.

Even Bi Hanlin, who has been in the frontier outside the Saiwai all the year round, couldn't help but nod his head again and again when he saw this batch of newly refined weapons.

Not only is the strength much higher, but it also gives people a frightening feeling.

The number of weapons refined in this way is not very large at present.

The reason is also very simple, because it is not so easy to achieve such a refining public welfare.

However, how can we quickly find solutions to these problems?

For Qin He, as long as there is a way to refine such iron tools.

If you want to complete mass production in the future, it is only a matter of time.

But it is undeniable that it will take some time to do this with the current technology.

On this basis, Qin He also thought of other ways to solve the problem of manpower.

Among them, the most admirable is the Qinhe River's use of water windmills as a power to forge iron ore.

At this point, Qin He didn't feel any surprises.

But for this era, it is indeed an extremely amazing technology.

Of course, this is not so much a technology as a bold innovation in thinking.

After all, in this era, water windmills have long been owned.

However, very few people would think of forging iron using water windmills as a power source.

Coincidentally, in terms of transportation, Qinhe has also carried out groundbreaking reforms.

No more reliance on human transport.

Various rails and pulleys are used to redefine the convenience of transportation.

Qinhe's reform in various technologies and conveniences has amazed many people.

As for the progress in firearms, it has been much slower.

Because of the environment, Qin He had very few opportunities to come into contact with modern firearms.

Knowing less about nature, coupled with the fact that the material requirements are demanding.

The difficulty of making modern firearms is not something that ordinary people can imagine.

However, in this regard, Qinhe has also found other paths.

That is the suppression of firepower.

If it were someone else, they might not know how to produce gunpowder in large quantities.

But Qin He is different, he not only has the method of concocting the formula of gunpowder.

At the same time, traditional firearms were improved.

One of the most noteworthy is the change from the traditional single-shot firearm to a multi-shot.

In fact, many people have tried this kind of change, after all, what Qin He has done is only some minor changes.

The only thing that kept them unalert was the problem with loading.

Now Qin He has developed a portable loading ammunition method.

It has undoubtedly allowed them to make great progress in this field.

Of course, at the moment, they have no place for actual combat, so if they want to verify whether such a method will work in actual combat, all this can only rely on Bi Hanlin's inference.

And Bi Hanlin naturally gave his own answer.

For an invention like Qin He, Bi Hanlin is naturally very optimistic.

However, he also made his opinion, although these things seem extremely convenient at the moment, especially in terms of the speed of reloading.

Even Bi Hanlin said that they could reload twice as fast as the regular army, and not only did they increase their firepower several times at the same time.

But the only thing worth mentioning is that such attrition will inevitably increase the burden of the march.

Therefore, such a situation can only be used in the city defense.

It is not suitable for long-range combat.

For Bi Hanlin's meeting with Qin He, he was naturally very willing to accept it.

In the final analysis, Qin He has not really experienced a major war, so he can be said to be a blank slate in terms of war.

After everything that needed to be done was done, Qin He had time to return to the island.

However, on the 4th day of Qinhe's return to the island, he received a message from Sangu.

When they learned this information, whether it was Qin He or Bi Hanlin, their faces were extremely ugly.

The news came from the third aunt from Jincheng, and this news was what Liu Qiang had encountered in Jincheng at the beginning.

Qin He did not choose to hide Bi Hanlin in this matter, but told him the news.

In fact, Qin He was also a little surprised in this matter, he didn't expect Qin He to tell him about it.

However, upon learning of this, both fell into a brief silence.

After a long time, Bi Hanlin asked.

"What do you think...... Is it possible that Xie Qingshan really betrayed us? ”

After listening to Bi Hanlin's words, Qin He gave his answer after a short thought.

"It's likely, but it's small."
