Lin Qinghen had no idea when Yin Hengxie came and when he left. He was just concentrating on comparing the two pieces of soil in his hands.
As he felt, in fact all the soil in Beizhou carries demonic energy, the only difference is the degree of demonic energy.
The content in the plantation area is much lower and has almost no impact, so it can be used as normal soil, but it is still there.
Lin Qinghen picked up a seed and planted it in the yard, then took some diluted ripening agent and observed its growth status.
After planting, the seeds did not die immediately. If ordinary people were to observe them, they would only see that the seedlings had just sprouted a tender bud and then quickly withered and turned yellow, losing their vitality.
But with the added bonus of extremely fine spiritual power and natural affinity, Lin Qinghen could see that the demonic energy in the soil looked like black particles, slowly seeping into the plants as they grew.
It seemed as if a war had taken place on this ordinary spiritual plant, with the spiritual and demonic forces colliding with each other, and finally the spiritual energy was completely defeated.
Lin Qinghen tried mixing two different soils together. If the concentration of the demonic energy in the soil was lower, the plants would last longer, but they would still be entangled by the demonic energy and die in the end.
Until it dropped to a concentration like that of the soil in the plantation, which was completely unfeeling for ordinary people. Because it was too thin, the demonic energy could not gather and could not break the outermost defense of the spiritual plants, so it had no effect.
Once the demonic energy successfully gathers in the soil, yellow-level plants basically cannot withstand it. Plants higher than yellow-level can resist it, but the higher the level, the more precious it is.
The requirements for artificial cultivation of spiritual plants above the Xuan level are very complicated. They have to be carefully cared for one by one. There are not many growing in the wild, and without the cover and protection of lower-level plants, ownerless things can easily be dug up by the roots, and the Northern Province seems to be becoming more and more desolate.
Of course, this kind of experience was not only experienced by Lin Qinghen, but also by many people in Beizhou, but none of them found a solution.
This ubiquitous demonic energy is somewhat different from the demonic energy cracks. So far, no plants have grown rapidly and violently due to it. I wonder what is missing.
This means that this kind of soil has always brought harm to Beizhou, and is one of the main reasons for the lack of resource production in Beizhou after the disaster.
Lin Qinghen frowned and repeated it several times.
Apart from those things that everyone knew about, he seemed to have seen something different during the short period of time when the plants were entangled by the evil spirit and died.
When the spiritual and demonic forces are entangled within the plant, it is not actually the beginning of the plant's withering.
On the contrary, at that time, the spiritual plant, out of its survival instinct, mobilized all its strength to fight back, and its overall condition was unprecedentedly good.
It's a bit like the sardines that were stimulated in the catfish effect, except that the other catfish was so strong that it was swallowed in the end.
From this perspective, the demonic energy in the soil can actually serve as a stimulus to promote the evolution of spiritual plants.
—Just control the quantity.
But Lin Qinghen tried several times and couldn't find the balance point in the middle.
And according to his observation, once it exceeds a certain degree, the concentration of demonic energy in the soil does not actually affect the strength of the invasion, but only affects the speed. In other words, it is the difference between dying quickly and dying slowly.
But if it is not excessive, the demonic energy will be too weak to trigger the special state of the spiritual plant.
Demonic energy has a natural corrosive effect on spiritual power. Even a little bit of it will cause yellow-level spiritual plants to be unable to withstand it.
It is no use just mixing the two parts of soil and adjusting the proportions. To achieve his goal, he has to get something else to assist in improving the soil.
Lin Qinghen was thinking about all these things until Yin Jiuxiao called him, then he came back to his senses.
"What's wrong?" He stood up and brushed off the dirt on his body, then asked, "Is the head of the Yin family gone?"
Yin Jiuxiao hummed, then turned his head slightly in the direction of his voice and said, "He just praised you."
"Are you praising me?"
"I praise you for being a good match for me."
Yin Jiuxiao heard Lin Qinghen laugh.
"Then I'll praise him too," Lin Qinghen continued, "He is still a man with a conscience."
Of course he has a conscience, Yin Jiuxiao thought, because of the guilt and promise he made many years ago, he has held on for so many years to preserve the name of his so-called lord.
But in fact, I can't take care of anything.
Being the head of a family is not something you can do just by having a clear conscience.
Yin Jiuxiao was just thinking about it in his mind, but Lin Qinghen said it directly.
"He is just too straightforward and not very smart. If he had been a little more careful, how could such a huge family business be ruined like this? Even if it was ruined for a while, there is no reason for the great Jiuxiao Jueyun Sword to be bullied by a villain like Xu Yaoyang."
He had gotten to know the Yin family a little better in the past few days, so he naturally felt a little emotional.
Even if Lin Qinghen had not married into the Yin family by accident, he still had a good impression of this family.
Risking one's life to save others is extremely rare. Before he came, he thought that no matter how poor the place was, it would still have some dignity. He didn't expect it to be in such a mess.
Yin Jiuxiao smiled and asked him half-truthfully, "If he hadn't done it, who else in the Yin family could have taken this position?"
Lin Qinghen washed his hands and helped him into the room. Then he sat down and slowly said, "You."
"Blue scar?"
Lin Qinghen was not joking. He stared at Yin Jiuxiao for a while, then held his hand and started to move it forward until he pinched his wrist.
"Jiuxiao," Lin Qinghen whispered, "I want to ask you a question. Can you answer it?"
Yin Jiuxiao did not hesitate and replied, "Of course."
But he didn't expect the question Lin Qinghen asked next.
"You have a demonic aura, don't you?"
Yin Jiuxiao: “…”
He was stunned for a moment and remained silent.
When did Lin Qinghen discover it
Since the two of them got married, they actually knew to some extent that the other had many secrets, which were not as simple as they seemed.
These two people understood each other's mentality to some extent, and tacitly did not point it out completely, but just tested each other, step by step.
Yin Jiuxiao knew that he could send a shadow to follow, but Lin Qinghen didn't have that ability. However, his observation and perception abilities have always been very good.
A few days ago, Yin Jiuxiao didn't feel anything, but he caught the moment.
He could catch even invisible and traceless shadows. When Yin Jiuxiao was practicing daily, there was something unusual on his body. It would be a lie if Lin Qinghen said he couldn't feel it.
Lin Qinghen was very careful about his life before. He had never come into contact with demonic energy and could not recognize the strange aura that occasionally floated from Yin Jiuxiao's body.
If Yin Jiuxiao completely merges the origins of the two veins, the characteristics of his spiritual power and demonic energy can be completely concealed, and Lin Qinghen will naturally be unable to be held accountable.
But at this moment, Lin Qinghen realized for the first time what the demonic energy was from the soil, and he suddenly remembered the abnormal thing on Yin Jiuxiao's body.
Lin Qinghen didn't think it was that complicated. He knew what happened before. When Yin Jiuxiao was seven years old, he was injured by evil spirit and his state of mind was unstable, which led to the backlash of his martial arts. But no one had ever said that there was still evil spirit remaining in this person's body.
Demonic energy has a corrosive effect on spiritual power. If it continues to exist in the body, it is a miracle that Yin Jiuxiao has lived for so many years.
In addition to the strange things about Yin Jiuxiao, Lin Qinghen had another idea in his mind—if he can survive, then my spiritual plant can also survive.
So he chose to point it out at this time, and he had many considerations.
Yin Jiuxiao didn't quite understand what Lin Qinghen was researching, but judging from the way he had been fiddling with the soil and muttering to himself in recent days, the word "demonic energy" appeared frequently when he was talking to himself.
After spending some time with Lin Qinghen, you will find that he is a very pragmatic person. It would be meaningless if he didn't do anything. Yin Jiuxiao immediately realized that this person treated him as a research subject.
But what he had on his body was not demonic energy, but demonic bones. His plants did not have demonic bones that could serve as support. The situation was very different.
"I do have demonic energy in me, but it can't help much. I can only ensure that I don't die." Yin Jiuxiao thought for a moment and answered directly, "But how did I manage to survive the next year? I can't explain it myself. I'm just lucky."
This cannot be considered lying.
Even though he had two lives, Yin Jiuxiao couldn't explain his early state of cultivation. He could only say that he was lucky and was born with some foundation, so he could withstand the conflict of the two energies.
Lin Qinghen looked at him for a long time, pondered for a while, and then continued to ask.
"Can you control the demonic energy in your body?"
Yin Jiuxiao: “… not completely.”
He hesitated for a moment, not intending to reveal his whole self to Lin Qinghen, but also not intending to lie completely.
The other party was also hiding something, so what he said was half true and half false.
"I've only been working hard for so many years and have acquired some ability to save my life," Yin Jiuxiao pointed at his eyes again, "You see, if I had extra skills, I wouldn't have suffered here for so long."
That's right, Lin Qinghen thought, Yin Hengxie could not protect Yin Jiuxiao, but instead brought him a lot of trouble. The Yin family is not a good place for him to stay.
When I was at the Lin family, I would talk about running away as soon as I felt a little confident. If Yin Jiuxiao had some abilities, he would never come back to this place. The resources in the City of Tears are scarce and it is actually not very suitable for cultivation.
What Lin Qinghen didn't expect was that this person, who had originally planned to run away, chose to come back on a whim because of him.
"Let me ask you another question. Can you control the demonic energy in your body to a certain extent?" Lin Qinghen asked him.
Yin Jiuxiao hesitated for a while, and then replied ambiguously: "To a certain extent."
He was not lying, and after a while, Yin Jiuxiao added another sentence.
"If Qinghen wants the magic energy, I can try to draw out some of it," Yin Jiuxiao said. He smiled at Lin Qinghen, "Although it hurts a little, it doesn't matter. My body is already like this, and there is no extra use for it. It would be meaningful to give it to Qinghen."
He has both sword bones and devil bones, and the aura of the two veins can be separated or combined. If Lin Qinghen wants to, it is easy for him to draw a few strands.
But when he spoke like that, that pitiful tone came out and Lin Qinghen felt that he was weak again.
Lin Qinghen pondered for a while, and had a vague idea in his mind: "Wait a minute."
Yin Jiuxiao was as well behaved as ever. It was pleasant to talk to him without much effort.
If he were around, it might be easier for me to do my research.
Lin Qinghen was silent for a long time, and finally just rubbed his hair and replied: "Forget it, there is always evil energy in your body, it doesn't feel good to think about it. Jiuxiao, when I find a way in the future, it will also be useful to you."
Yin Jiuxiao didn't have much expectation for this, but Lin Qinghen said it seriously, as if it was a promise.
He certainly did not relax, and was digging the soil these days. He did not allow Yin Jiuxiao to extract any demonic energy for the time being. Unfortunately, those spiritual plants grew and died in his hands, and not a single one survived.
After Yin Jiuxiao was pointed out by him, he felt much more at ease. He practiced openly in the room a few steps away.
He had thought before that it would take time for him to fuse the origins of the two meridians. Even if he did it slowly, it would take a long time.
Although he had good control over it, his breathing occasionally became unstable during his training, and he was worried about how to conceal it in front of Lin Qinghen.
In fact, there is no need to worry or hide.
Lin Qinghen knew that he was practicing, so he moved very carefully when entering and leaving.
He asked about the things he wanted and cared about, and ignored the rest. Occasionally, he would ask Yin Jiuxiao about his feelings and understanding of demonic energy. Yin Jiuxiao answered naturally, which gave Lin Qinghen some very useful tips.
Lin Qinghen was not an idle person. He was still busy. All he had in his mind was research. He had no time to get to the bottom of Yin Jiuxiao.
As long as the other party remained obedient and well-behaved, Lin Qinghen would be very satisfied. He also thought that Yin Jiuxiao couldn't see it, so he didn't avoid him in many of his actions.
Two people lived in the same room, with complicated stories between them, but they managed to reach a balance so simply, with a tacit understanding and lived in peace with each other.
Days like this were much more interesting to both parties than before. And they both really needed a quieter environment in the near future, so they naturally enjoyed it.
