Jiang Xingchen did not stay in the imperial capital for a long time, it was about to be the end of the month, Mei'er would come back to celebrate his birthday, and he had to rush back to Xingchen Ling.

As for solving the matter of the Sixth Legion, he really couldn't think of a way for a while, so he could only go back and slowly think about countermeasures. Fortunately, the Sixth Army is fully defending, and the two sides are tug-of-war, it is not a one-sided situation, there is no problem in a short time, and the supply of Qi Yueling can also keep up, and the impact will definitely be there, but it will not be too big.

The marshal and others also knew that Jiang Xingchen needed to be considered, and the previous two times were the same situation, and Jiang Xingchen was not able to come up with a solution.

When he went back, it was still the old man who took Jiang Xingchen with him, and the speed of the carriage was too slow. The old man couldn't stop complaining, saying that he didn't owe money to this kid in his previous life, he fooled himself into inserting Wei Ning's urinary catheter, and he still had to serve him.

It was already June 28th when he returned to Xingchenling, and Jiang Xingchen went to the tea garden first, which was a big treasury, and there was no mistake.

Hundred acres of tea seedlings grow vigorously, especially those cuttings of tea trees, grow even faster, already calf height, the main trunk has the thickness of an arm, it seems that this year can pick winter tea.

In addition to being happy in his heart, Jiang Xingchen took out the queen ant, Jiang Xingchen had been hesitating to release the King Kong ant all the time, worried that it would hurt people. Later, he found out that he could control the queen ant, but he didn't know where to put the ants.

Now that he has finally made a decision, it is really suitable to use King Kong ants to protect the tea plantation.

At this time, a fence had been set up around the tea garden, and Jiang Xingchen had sent some vitality to the queen ant. I put it in the tea plantation.

In addition, in addition to the tea garden, Jiang Xingchen also ordered people to build simple houses. Du Rushan was transferred, and he was followed by half of the brothers of the earth-shattering mercenary group and a hundred private soldiers.

Almost all of these private soldiers were given to him by the Marquis of Dingbei, and there was no problem with their net worth background, but the number was a little small, only two hundred. It's still far from his upper limit of 1,000 private soldiers.

There's no way around it, the rules he sets are too strict. Du Rushan couldn't recruit at all.

The private soldiers sent by the Marquis of Dingbei still had some pimples in their hearts at first, after all, this is already the northernmost part of the empire, and it belongs to the bitter cold land. How can Hongyuan City stay comfortable. But. Dingbei Hou's order could not be disobeyed.

But when they rushed to Qingshan Village and saw the neat houses and streets, the vigorous wheat seedlings, and the sunflowers that could not be seen at a glance, they realized that they were wrong, what kind of bitter cold place is this, it is even richer than Qi Yueling.

Not only that, but Jiang Xingchen's salary for them was also much higher than before. Especially the food here was brought by Jiang Xingchen. The food cooked by those village women is not inferior to that of the restaurants in Hongyuan City.

It's delicious, it's easy to live, and the salary is quite large, the key is that Lord Jiang is kind and doesn't take a shelf, which makes them feel very comfortable. Of course, they are all willing to stay.

After arranging the manpower of the guards, Jiang Xingchen instructed Du Rushan a few more words, and then hurriedly returned to the territory.

At this time, everything seems to be thriving, the construction of the new town has been in the second half, and nearly half of the various buildings have been built, and the prototype of the town can be seen standing on the hill.

The Duan family father and son told him that the construction period would only be advanced, not delayed, and if it was fast, the work would be delivered in mid-September.

Jiang Xingchen was very satisfied, and walked all the way back, seeing that the three hundred orcs were busy, and the ten thousand acres of cultivated land were planted with vegetables again.

The 10,000 acres of cultivated land outside the village are all pale yellow at a glance, and the sunflower trays with the size of a basin are raised high, and the green of the grain looks very inconspicuous.

Back in the village, Jiang Xingchen instructed Han Xiaowu not to let people disturb him, so he went headlong into the lord's mansion. The role of the Yuan Stone needs to be excavated, the territory is getting bigger and bigger, and there are more and more places that need vitality, and you can't just rely on your own formation. This time, Xuanyuan Tianzong made the Yuan Stone Explosion, which gave him a certain amount of inspiration, and he had to study it carefully.

In addition, the composite force array has been developed and needs to be explored. If the problem of the Sixth Legion is to be solved, it must study the effect of this new formation. Otherwise, he would have no other means at his disposal.

In the room, Jiang Xingchen took out the Yuan Stone, held it in the palm of his hand, and said secretly in his heart: "If the Yuan Stone is broken, the internal vitality will be dispersed, but how can it explode......

Thinking in his heart, Jiang Xingchen subconsciously squeezed hard, and suddenly felt a pain in his palm.

"Oops!" Jiang Xingchen softly exclaimed in pain, and scolded secretly: "Stupid, I'm not a martial artist, how can I have such a big hand to crush and crush the Yuanshi...... Wait!"

At this moment, Jiang Xingchen suddenly had a flash of inspiration: "Yes, the Yuan Stone will only leak when the Yuan Qi is broken, which means that the Yuan Qi is sealed in the Yuan Stone! If the internal Yuan Qi activity intensifies, will the Yuan Stone be broken?"

With this idea, Jiang Xingchen immediately operated the formation, and the frequency of the Yuanquan's vibration accelerated, using the vibration frequency of the external Yuanqi to affect the frequency of the Yuanshi's internal and Yuanqi.

With the barrier of Yuanshi, the effect of frequency resonance is very small, even if it is a seed, it can have a blocking effect, let alone Yuanshi.

However, the vitality in the Yuan Stone can be absorbed, which indicates that the fluctuations in the outside world can also affect the internal vitality, but at a slightly slower speed.

Jiang Xingchen's breathing method was running faster and faster, and he felt a buzzing vibration sound in his head. A quarter of an hour later, the Yuan Stone in his hand suddenly shattered with a snap, and an extremely rich Yuan Qi rushed out.

In Jiang Xingchen's perception, the intensity of this vitality can almost catch up with the vitality he has gathered, and the vibration frequency is extremely fast, it has more than doubled all at once, and his vitality frequency can't keep up.

"Such a high frequency!" Jiang Xingchen exclaimed in surprise, wanting to continue perceiving. But in just a moment, this vitality merged with the external vitality, as if water droplets fell into the sea, and disappeared without a trace in the blink of an eye.

Although he didn't perceive the Dao, Jiang Xingchen had a new cognition, the Yuan Stone was broken, and the vibration frequency of the Yuan Qi released was quite high.

"Maybe it was affected by my resonance just now, I wonder what will happen if it shatters directly?" Jiang Xingchen said secretly, got up and walked out of the door, found a hammer, and returned to the house.

This time, Jiang Xingchen put a yuan stone on the ground, picked up the hammer and smashed it hard.

"Bang!" Yuanshi was smashed into pieces, and the rich vitality inside rushed out.

This time, Jiang Xingchen had been prepared for a long time, and he had been capturing the movement of the vitality. He found that at the moment when the vitality rushed out, the vibration frequency did increase sharply. However, it is not as frequent as just now.

"I understand!" Jiang Xingchen let out a long breath, and the corners of his mouth hooked up: "It turns out that the Yuan Qi inside the Yuan Stone is released, and the frequency will increase dramatically, but because the time is too short, it will be assimilated by the outside Yuan Qi, so it has not been discovered...... My first experiment showed that the higher the frequency of the vibration of the Yuan Qi inside the Yuan Stone, the higher the vibration of the Yuan Qi when the Yuan Stone shattered and exploded!"

After a deep groan, Jiang Xingchen lowered his head and picked up a piece of gravel on the ground, and muttered: "If there is a closed space and the Yuan Stone is broken by gradually increasing the method, will the fluctuation frequency of the Yuan Qi be assimilated by the outside world immediately?"

With this question, Jiang Xingchen immediately did the third experiment, using a piece of hard solid wood, digging out two semi-circles of space, placing a yuan stone in it, and then closing the two semi-circles to form an inner round ball, and leaving a small hole.

According to this small hole, Jiang Xingchen once again operated the breathing method, intensifying the vibration of the vitality around the Yuan Stone, causing the resonance of the Yuan Qi inside the Yuan Stone.

A quarter of an hour later, the Yuan Stone shattered, and the rich Yuan Qi rushed out. But this time, due to the enclosed space, the frequency of the Yuan Qi was not immediately fused, but instead increased the frequency of the surrounding Yuan Qi.

Violent fluctuations in vitality cause the internal air to expand at an accelerated pace...... Jiang Xingchen felt the whole process.

"Sure enough, as I thought, Jiang Xingchen immediately left his hand, and a small hole appeared in the closed space, and the vitality immediately sprayed out from here, exchanging with the external vitality, and the frequency dropped again, merging into the vast world.

The rapidly expanding gas was also vented due to the breakage, and the wood was not pushed open.

"That's the principle!" Jiang Xingchen moved his fist with force, and a smile bloomed on his face: "Just like a pressure cooker, using the Yuan Stone to crush, the frequency of Yuan Qi rushing out suddenly increases, which intensifies the frequency of Yuan Qi in the enclosed space, causing the internal air to expand, and when the internal pressure reaches a certain level, the enclosed space will be broken...... This enclosed space has become a big bomb!"

"However, the space I used for the experiment was only a small one, and the enclosed space prepared by the Xuanyuan Heavenly Sect must be very large, otherwise it would not be enough to sweep a radius of several miles. I'm afraid there will be tens of thousands of yuan stones used...... That's a lot of money!"

As for the method, it is not difficult for Jiang Xingchen to guess that he only needs to use the method of continuous aggravation to crush a batch of yuan stones first, increase the internal fluctuations of the space, and the strong resonance will cause the fragmentation of other yuan stones, and when the pressure reaches a certain level, it will be a space explosion.

"Whew~" let out a long breath, Jiang Xingchen smiled and muttered: "The cultivation of grain is to introduce vitality little by little through the influence of resonance...... If the proportion of the fluctuation of the vitality is matched after the explosion of the space and the Yuan Stone, then the space will not explode, and the frequency of the internal Yuan Qi will also change accordingly, and the grain seed will be put into it...... Ha Luha, I see!"

Thinking of this, Jiang Xingchen was almost so excited that he jumped to his feet, and through the explosion of the fake yuan stone vein, he finally solved the problem that he continued to solve. In the future, grain seeds, vegetable seeds, flower seeds, and even several kinds can be kept in this way.

Of course, this has to go through many experiments to achieve the best proportions. Not only is it dangerous, but it also costs a huge amount of yuanshi.

Later, he thought that if the enclosed space was opened to a small hole and the high-frequency vitality inside was released outward, then he would not need to convey the gathering vitality to the land in the future.

"Hehe, the problem that plagued the development of the territory has finally been solved!And, with this method, I should be able to easily upgrade the title......" (To be continued......)
