The food problem has always been a hindrance to the development of the empire, and the annual food production is about to be enough to feed more people, so although the empire is large and has a lot of arable land, the population does not exceed 100 million.

And once there is a natural disaster or something, life will be even more difficult, and it will even be difficult to support the army to fight for a long time.

If Jiang Xingchen's method is feasible and can successfully increase the yield per mu, it is conceivable how much credit he has, and it is possible to be directly promoted to earl.

Jiang Xingchen opened his mouth and laughed all the time, unable to hide the joy in his heart...... It took a long time for him to calm down and reconsider the problem.

"Whether this method can be implemented remains to be tested, and even if it does, if you want to test the results, you will have to wait until next year to know the way, and it still can't solve the problem in three months...... In addition, how many yuan stones are needed to be able to affect the grain species, if the need for too many yuan stones, more than the value of the yield itself, it will be worth the loss...... Besides, if you want to release the gas in the Yuanshi and supply the land, what do you need to do, you can't dig a big pit under the cultivated land, and then make a closed space......

Calming down, Jiang Xingchen thought about it carefully, and the questions appeared one after another in his mind, and he realized that he had just obtained a theory, and it was still very early before it was actually implemented.

"Think about it, Xuanyuan Tianzong doesn't know how many years of exploration it has taken to have the complete system now, how can it be possible to do it day and night!"

With a secret sigh, Jiang Xingchen let out a long breath and said secretly: "No matter what, the method and direction are finally understood." It's no longer the same as before, as long as you go through the test, you will definitely be able to succeed. ”

The mind eased slightly. Jiang Xingchen thought of another question, why did the Yuan Qi suddenly vibrate and accelerate when the Yuan Stone was broken and rushed out, could it be that there was another mystery inside the Yuan Stone?

This thought popped up, and Jiang Xingchen's heart began to itch again, and he immediately took out a piece of Yuan Stone and began to study it.

But. Yuanshi is not a seed and a demon beast, it can affect the inside through the resonance of the vitality, but it is difficult to use the gathered filaments of the vitality to penetrate it.

I tried several times in a row but it didn't work. Jiang Xingchen frowned, and began to speed up his breathing method, and the Yuan Spring in his brain began to roar.

But even so, the gathered Yuan Qi still couldn't penetrate into the Yuan Stone. That barrier just can't be breached.

"It's weird. Why is it okay to resonate, and if you gather your vitality, you can't penetrate the ......" Jiang Xingchen was full of questions, and at the same time, he was a little unbelieving, and he worked hard to make the breathing method work faster and faster.

"Buzz...... The tremors in his head grew faster and faster, and before he knew it, his breathing method had reached an extremely high speed, and the rhythm and rhythm of his breathing echoed in the room.

It was at this time. Suddenly, he felt something unusual. It didn't come from the Yuan Stone in his hand, nor did he gather the Yuan Qi and probe into it. It's happening in his head.

He clearly saw that on the complex lines of the compound force array, streams of obvious mist were flowing.

"This ...... What is this, I've never seen it before?" Jiang Xingchen showed a look of surprise, and his mind temporarily left Yuanshi, carefully watching the situation of the formation.

"Could it be that I used to be too slow to operate the breathing method, so this mist didn't appear...... But what does this do, is it just circulating along the line of the formation......"

As soon as this idea came to him, the mist flowing along the formation suddenly detached from one position of the formation and began to wander around his body, and there was a warm feeling everywhere he passed.

"Hmm!" Jiang Xingchen's eyes widened suddenly, and he was stunned: "This feeling...... How can it be like what they say about internal qi?"

Holding this question, Jiang Xingchen's consciousness flashed, thinking that those mist came to the palm of his hand.

Sure enough, the next moment, the mist that swam through his body all gathered in his palm.

"I'll go! It's really internal qi, and I have internal qi too! Is that ...... Oops!" As soon as Jiang Xingchen wanted to practice martial arts, he suddenly felt that the formation in his brain rose, as if it exploded, and the internal qi in his palm also dissipated.

"I'm the next Ao, I scolded the person next door, what do you do if you don't let me practice martial arts give me internal qi, do you want to watch it?" Jiang Xingchen couldn't help but scold in his heart, he was too lacking in morality, he didn't let him practice martial arts, and he made his internal qi to covet him.

After taking a few deep breaths, Jiang Xingchen shook his head, and secretly said in his heart: "No, the formation can't be useless! Although internal qi can't be used for cultivation, it may have other uses...... That compound force array, maybe you need to use internal qi!"

Thinking of this possibility, Jiang Xingchen immediately ran the breathing method again, re-mobilized the internal qi, and gathered it in the palm of his hand.

"What's the use of internal qi, and what does it have to do with the compound force array...... Can you probe into the inside of the Yuan Stone......"

With such a question, Jiang Xingchen held the Yuan Stone in the palm of his hand, his breathing intensified, and immediately the internal qi rushed out of the palm, colorless and formless.

According to Jiang Xingchen's original intention, he wanted to explore the inside of the Yuan Stone. But the moment he held up the yuanshi, he immediately felt a point on a diamond-shaped yuanshi.

"How can you perceive this position...... Jiang Xingchen's eyes lit up, and he moved the Yuan Shi from his palm to his fingertips, and the position where his fingers were held was exactly that.

Looking at the Yuan Shi that stopped steadily at his fingertips, Jiang Xingchen smiled: "This is where the center of gravity lies...... Compound force array, it turns out that force analysis can be carried out, I understand!"

Then, Jiang Xingchen played, from small cups and bowls to tables, chairs and basins, he knew where the center of gravity of the Dao was as soon as he put his hands on it, and he could clearly feel the force distribution in each position.

"That's what the compound array does, it's too much of an aid to me in making things, that's what it does...... Haha

Later, after testing, Jiang Xingchen found that his internal qi was as soft as cotton thread, and he couldn't penetrate into the Yuanshi at all.

However, at this time, he didn't care about Yuanshi's affairs, the function of the compound force array was highlighted, and he had to explore it as soon as possible......

While Jiang Xingchen was preoccupied at home, Mei'er was rushing back from the other direction, less than ten miles away from the mountain village at this time.

When she came back this time, she was not alone, Yu Zhen, Zhang Yingying, Song Ning, and Tan Dong all came together.

Jiang Xingchen's birthday, Mei'er prepared gifts, how could Yu Zhen let go of this big gossip. Before Mei'er left, she kept asking to come with her, wishing the lord to come of age at the age of eighteen.

Not only that, Yu Zhen also put on a few other people, afraid that Mei'er would not agree, and said that a few people were safe together, and Mei'er was too dangerous to walk alone. Hearing this, Song Ning and Tan Dong both blushed a little, not to mention that there are four great masters of the Yuan Qi Realm around Mei'er, it is that mysterious person, who can kill seven masters silently, who dares to be unfavorable to Jiang Mei'er.

Mei'er saw that a few people were enthusiastic, and it was really hard to refuse, and she thought of her brother's adult birthday, and it was always good to be lively, so she didn't refuse.

When a few people asked for leave, the Moon Shadow Kingdom Academy did not have any obstruction, only said that they would go early and return early. This surprised Yu Zhen and the others.

If a student takes a leave of absence for a month, if it is not an important matter, the college will never approve it. They all prepared reasons, and Zhang Yingying even prepared a lie that the head of the family was seriously ill, but who knew that it was useless at all, but the academy directly approved it without saying a word.

After nearly ten days of long-distance carriages, several people were very tired, and the carriage was a little stuffy, and several people's foreheads kept oozing sweat.

"Mei'er, it's not yet, the lord's territory is biased enough!" Zhang Yingying said while fanning the wind.

"Hehe!" Mei'er smiled and said: "Our star leader, but the northernmost part of the empire, beyond the hills of less than a thousand miles, is the Orc Alliance, of course, it is remote!"

"Hey, how did the lord choose such a place as his territory, how good it would be to have a rich place, with the contribution of the lord, the Marquis of Dingbei will definitely give the best place!" Zhang Yingying said.

Mei'er shook her head and said, "My brother and I are both from Qingshan Village, and that is our home...... Besides, now my brother has built the territory very well!"

"Oh!" Yu Zhen and the four nodded, but no one went to their hearts, in such a remote place, it is inconvenient to purchase materials, transport, and transfer personnel, how can it develop well. They all thought that Jiang Meier wanted to save face, so they said this.

However, they didn't refute Mei'er's current identity, they didn't dare to say anything more, so that the little girl would lose face.

Mei'er didn't notice the thoughts of several people at all, her eyes kept staring out of the car window, and her thoughts had already drifted to the star collar.

"It's been three months, is my brother okay? must have been busy, hmph, never listen to me...... Now is the best time for the crops to grow, and the whole village is busy...... How is Xiang'er's bee-like appearance, has Xin'er's medical skills improved, and is Nier still so greedy......"

The closer she got to the mountain village, the deeper Mei'er's thoughts became, and the appearance of everyone in the village appeared in her mind in turn.

"Wow!" Just as Mei'er's thoughts were drifting, an exclamation suddenly appeared in the carriage, which woke her up.

Mei'er turned her head and saw four people staring directly out of the car door, and in the distance was the construction site of the new town, countless craftsmen were busy, and they could hear the noise coming from the distance in the carriage.

"Hehe!" Mei'er smiled happily, pointed ahead and said, "There is a newly built town in the territory, with an area of about thirty square miles...... Looking at the current appearance, the house is nearly half up, and it should be almost finished!"

"Gollum!" Song Ning muttered with a mouthful of saliva under his eyes: "To build a new town in this location, in more than thirty bungalows, the personnel, materials, and freight are much higher than elsewhere, how much does it cost?"

Mei'er shook her head and said, "It's not clear, when I left, I was still laying the foundation, and I had already spent 10 million citrine coins!"

"What!" Song Ning and Tan Dong's eyes instantly widened, their eyeballs were about to pop out of their sockets, their mouths were open, and their chins seemed to fall to the ground. Yu Zhen and Zhang Yingying are staring in their eyes...... (To be continued......)
