The environment in the house is the same as before, and there is no problem with feng shui, Zhang Tianyi has already checked it carefully last time, but for the sake of insurance, Zhang Tianyi still confirmed it again.

If the problem is not in feng shui, then it can only be that there is a problem with the things in the room, last time Zhang Tianyi noticed the potted plants raised by Xu Ruoyan, but at that time, there were only some yin precipitation in the potted plants, and the amount was not very large, and it was not enough to affect people.

After thinking about it for a while, Zhang Tianyi decided to make sure again, and walked into Xu Ruoyan's room, Zhang Tianyi's brows furrowed, the temperature in the room was terrifyingly high, and Zhang Tianyi felt that it was at least forty degrees.

Although it is the height of summer, the temperature is obviously still a little too high, and the true qi is running to the top of Tianyantong, Zhang Tianyi looked into the room again.

I saw that in the originally empty room, under the eye of the sky, there was a large area of black gas, which gathered on the roof, like a layer of black clouds in the room.

Looking at the source of the black qi, Zhang Tianyi's eyes narrowed slightly, and sure enough, it was still the weird potted plant that was doing tricks.

Originally, the potted plant that only gathered some yin qi and accumulated it in the pot, now it is like a yin qi production machine, from every leaf of the potted plant, it is constantly emitting black qi, which is the source of such a rich black qi in the room.

Yin and Yang are two opposing sides, but they are also two sides that transform each other, and many people believe that if the body is cold, it is the effect of Yin Qi, and if it is very hot, it is the effect of Yang Qi.

But this is not the case, if the yin or yang energy has reached a point where it can be perceived, then most of the effects will be the opposite of the one themselves.

Just like the yin qi condensed in Xu Ruoyan's room now, the yin qi has accumulated to such an extent, and in the room, what is manifested is no longer cold, but hot, just like a furnace, this is the principle that the cathode generates yang.

If you stay in the room for a long time, you will feel hot at first, but over time, these yin qi will be absorbed by the body's breathing action and enter the person's body, and then you will start to feel cold.

When yin qi accumulates in a person's body to a certain extent, the person will begin to be greatly affected by yin qi and become yin and cold physique, which will only affect people's mood, temperament and character at first, and then slowly change people's fortunes.

After a long time, the whole person will undergo earth-shaking changes under the transformation of yin qi, Xu Ruoyan has now reached the first stage, that is, yin qi should already affect her mood.

Therefore, Zhang Tianyi must first solve these yin qi in the room, otherwise, Xu Ruoyan's mood will get worse and worse, and then his temper will become worse and worse, until finally, he will become a nervous disorder.

The best way to deal with yin qi is naturally to use yang qi to kill it, Zhang Tianyi first took out the potted plant and put it in a place where the sunlight can shine outside, and used the sunlight to suppress the yin in the potted plant.

Then rummaged through Xu Ruoyan's home, and Zhang Tianyi had to admit that Xu Ruoyan's home really had nothing but clothes and cosmetics.

Of all the things in the whole room, it is estimated that only Xu Ruoyan's computer is something she often uses, and after thinking about it for a while, it is obviously too late to go out and find something with enough yang energy now.

Zhang Tianyi had no choice but to take Xu Ruoyan's computer, walked to the room, opened the computer and searched for it, found a song from the children's choir, released the song, and then began to arrange the formation in the room.

What's the use of this song?

It is to make Zhang Tianyi's mood a little better, because next, he wants to use his yang energy to eliminate these yin energy in the room.

Fortunately, he has cultivated his true qi, and under the warmth of his true qi, his yang qi is very sufficient, otherwise, he would use his own yang qi to consume so much yin qi, and when it is finished, he himself will not be far from the end of playing.

After the formation was arranged, Zhang Tianyi took off the clothes on his upper body, his eyes were open, his eyes were deep looking at the yin qi like a black cloud above his head, he took a deep breath, and Zhang Tianyi walked to the middle of the formation.

The true qi in the dantian qi sea was guided into the soles of the feet, and then through the contact between the soles of the feet and the ground, the true qi was operated into the formation, and the true qi followed the lines of the formation, and after the entire formation, a faint light lit up from the room, forming a mysterious rune.

With Zhang Tianyi as the center, the black cloud above his head slowly rolled up a whirlpool and began to sink downward, at the moment when the black qi touched his body, Zhang Tianyi's whole body trembled slightly, and the yin qi entered the body, which was not so comfortable.

However, under Zhang Tianyi's feet, with the support of the formation, after these yin qi entered his body, the light of the formation under his feet suddenly became more dazzling.

Under the illumination of the light, the black gas began to dissipate little by little, and after nearly an hour, Zhang Tianyi opened his eyes, at this time his face was pale, his body was also cold and hot, and fine sweat was all over his face.

Looking up at the yin qi above his head, after his hour's consumption, the black qi on it has been much lighter, although it has not been completely eliminated, but this amount of yin qi, as long as the window of the room is open, can let the sunlight shine in, in this hot summer, it will automatically dissipate in less than two days.

After getting dressed and walking out, Zhang Tianyi saw that Xu Ruoyan hadn't woken up yet, his heart moved slightly, and he walked to Xu Ruoyan's side, just in time to see the yin qi coming out of the potted plant that he put outside the balcony shining under the sun was converging towards the soles of Xu Ruoyan's feet.

His heart sank slightly, and he picked up Xu Ruoyan's soles, and then he saw that on Xu Ruoyan's soles, there was a blood-red dot, and it was this dot that was absorbing these yin qi.

Zhang Tianyi stretched out his hand and tried to wipe off the lower red spot of Xu Ruoyan, but found that the red spot grew from Xu Ruoyan's feet, and it could not be wiped off, and Zhang Tianyi had no choice but to deal with the potted plant first.

I walked to the window, took the potted plant in my hand, looked left and right, and saw that there seemed to be something in the soil of the potted plant, and reached out and buckled it out, it was a piece of black rotten wood, and I put it between my nose and smelled it, and there was no strange smell.

But after this rotten wood was dug up, the yin qi emitted from the potted plant was significantly reduced, and his heart moved slightly, he found a bottle to fill the piece of wood, and then put the potted plant back, and Zhang Tianyi left Xu Ruoyan's house.
