Daqin Engineers

The next day Shen Bing was pulled by Xu Ying to make fat.

To be honest, Shen Bing is not willing to toss this thing because the taste is really unflattering.

It's just that Xu Ying said hello to Wang Jian in advance, so he didn't want to go.

Composting is also called simple composting because it is easy to prepare.

Shen Bing teaches half-pit refining.

First dig a hole in the flat ground, about three feet deep, six feet long and wide.

Then put two crossed wooden sticks on the ditch, and then piled garbage and excrement into the pit.

Mainly straw, weeds, leaves, etc. It is best to chop them first.

Then add all kinds of feces.

Sprinkle some water, excrement and urine, and add some water to make it moist...not wet and not perishable.

The high pile is like raising a small mountain bag and then sticking a two-inch thick layer of clay on the outside... This is done to maintain the temperature in the pile to accelerate the decay and kill the maggots.

Finally, take out the wooden sticks on the previous shelf as vent holes.

It is so simple that Xu Ying looks a little unbelievable.

"That's it?"

Shen Bing replied:

"What if? It's just fattening!"

Xu Ying asked with some suspicion:

"But so and so, where does this fat come from?"

It really needs to start with microorganisms...

Forget it.

Shen Bing replied:

"The subordinates don't really understand."

"But doing so seems to make more fertilizer for the few manures and make it more fertile."

"Just try to see if it works."

Xu Ying nodded in agreement.

He has prepared a few experimental plots, in fact, not a few but many.

Xu Ying is still quite professional in this regard, after all, he is a farmer.

Xu Ying's arrangement was to divide a field with the same fertility into several pieces of the same area.

One piece does not use any fertilizer as a reference.

Then it is divided into two types of six fields.

One is the use of ordinary farmyard manure, with small, medium, and large amounts of fertilizer.

The other is the use of retting fertilizer, which also applies small, medium, and large amounts of fertilizer.

In this way, the fertility of retting fertilizer can be compared by reference when harvesting next year.

In addition, in order to avoid accidental conditions such as floods, winds, locusts, etc., the experiment failed.

Xu Ying opened up several experimental fields in the same way in other places, even in the three counties and even all counties in the Qin Kingdom.

This is not purely to deal with accidental situations, but Xu Ying wants to know whether there is a difference between this fertilizer in different regions and different climates.

Shen Bing secretly said that the influence of this peasant family was indeed extraordinary, and it was extraordinary when he experimented.

But this also seems normal.

This experiment has a cycle of one year. If you have any data, do you have to wait another year?

Therefore, in the first year, all aspects should be considered clearly and done at once.

Tuntian proceeded step by step in this way. With the massive investment in waterwheels and dump trucks, everything went smoothly.

However, as the agricultural period is approaching, there are difficulties in growing grain.

This is not because Yingzheng has been poorly deployed.

In fact, Yingzheng's deployment is very reasonable, and he adopted a staged deployment method to save time.

The so-called segment deployment is to divide the deployment distance into two or even several segments for deployment.

For example, there are 1,500 miles from Xianyang to Handan. It would take one month to transfer the grains directly, and it would be too late.

But if it is divided into two stages of deployment... Xianyang to Pingyang, and then from Pingyang to Handan.

The two food dispatch teams set off at the same time.

That is, the grain seeds were transported from Xianyang to Pingyang, and Pingyang also transported grain seeds to Handan.

In this way, Pingyang's grain crops are not small at all, which is equivalent to transporting Xianyang grain to Handan.

The delivery time has been halved.

This method of deployment was very common in ancient times when transportation was inconvenient, especially when food was urgently needed on the battle front.

The problem lies in the deployment...

Zhao Guoxin killed the people and was unstable, and was affected by the 400,000 Zhao army killed by Bai Qi. Many people chose to fall into the grass.

They joined forces with the disbanded Zhao Jun in the wild, and they formed large and small bandits in the three counties.

If these bandits want to survive, they must rob food.

But at this time, the food team is on the road...

So today a small team, tomorrow a small team, from time to time, the food team is intercepted by the bandits halfway.

There are even cases of malicious destruction of bridges.

This is usually done by small-scale gangsters. They can't defend the food team hard. They can only break the bridge and block the food team overnight in front of the river, so they can go fishing in troubled waters to steal food.

It's fine if it's just stealing food.

Perhaps out of hatred for Qin Jun, after they had stolen the grain, they would often set a fire to burn the grain that could not be taken away.

So the food delivered to the three counties was very tight for a while.

These are nothing to do with Shen Bing and his team. They are artillery without armor, and it is not their turn to protect food from the bandits.

only……

A large number of soldiers were transferred out of the city either to protect food or to suppress bandits, and Handan had to defend the land and the city to defend. There was a shortage of soldiers in the more than 100,000 troops under Wang Jian's system.

Then one day, Shen Bing received the order:

"The artillery is responsible for city defense from today."

"At the same time repair the city wall."

...

This is fine.

Basically no one will come to attack the city at this time.

Let the craftsman take charge of the city defense and repair the city while defending the city. That is not a waste of labor.

Shen Bing and his party are in charge of the North Gate.

This is a bit ironic. At that time, Shen Bing and others attacked the North Gate, and now they are responsible for filling in the gaps that they used to hit the trebuchet.

But Shen Bing couldn't complain, because it was much better compared to Tuntian, at least not suffering from mosquitoes and leeches.

While Shen Bing and others were busy in the three counties, someone from Yan State was keenly aware of the danger.

"Report..." A spy sent a piece of information to the hands of Prince Ji Dan of the Yan Kingdom.

Ji Dan unfolded the information, and immediately took a breath:

"Wang Jian really dumped all the arable land in Zhao country?"

"How can they farm this many fields?"

The spy replied:

"It's true."

"They made waterwheels and dump trucks for drought control. It is said that they were made by an engineer named Shen Bing."

"These waterwheels and dump trucks can lead a large amount of river water into ditches for irrigation."

"So the drought in the three counties of Zhao State is no longer a concern."

Ji Dan was surprised again, and began to think:

The big thing is not good!

After Qin destroyed Zhao, it bordered Yan.

He originally said that the Qin army could not attack the Zhao Kingdom during the drought.

Now that the country of Zhao is under severe drought and Wang Jian has emptied all the arable land...

This is clearly for the northern march next year.

In fact, Ji Dan has misunderstood this thinking.

No matter how Qin Jun would destroy Wei State first.

In this regard, the Wei State is more likely to be destroyed when surrounded.

On the other hand, Wei is behind Qin, if it is immortal, it is like a thorn on the back.

But Ji Dan, a fan of the authorities, took it for granted that the next one was the Kingdom of Yan.

So for the present...
