After returning to Fan Lingling's house, Zhang Tianyi went to Fan Lingling's room to take a look, and saw that she was already asleep, so he didn't make any noise about her, sat on the sofa in the living room, took out the black and rotten wood, and put it in front of his eyes to look at it carefully.

After looking at it for a while, Zhang Tianyi still didn't find anything abnormal, there are many factions in Xuanmen, just the subordinates of Daomen, there are fortune tellers, xiangshi, feng shui masters, qi practitioners, etc., not to mention that outside the Daomen, there are also witch gates, Gu gates, corpse gates, ghost gates, and so on.

In the past, Zhang Tianyi heard Master say that each family has its own mysteries, and the tools they use are all based on their own methods, after thousands of years of experience.

For example, the Maoshan technique, the peach wood is their best magic weapon, all the methods of the Maoshan technique can be performed through the peach wood, and for example, the people of the Gu Sect, poison is their most important item, without poison, they can't even refine the Gu worms, let alone cast the Gu technique.

Except for the people in their own sects, no one knows what the other party needs to use to perform the method, and in the early years, even the two apprentices taught by a master were different from each other.

Therefore, it is basically impossible for Zhang Tianyi to figure out what this piece of black wood is for, unless he can catch this person and pry it out of his mouth.

However, Zhang Tianyi couldn't know what this black wood was for, but it didn't prevent him from fighting with the other party again through this black wood.

The so-called "bridging method" is to use a fixed medium to match, find the number of lives of the target, and then start from the number of hits to cause damage to the opponent.

Since this guy used this black wood to create yin qi, then the best way to deal with him is, of course, to attack with yang qi, went downstairs to the vegetable market and bought a big rooster, asked the chicken seller to help him kill it, took a bowl of rooster blood, and carried the chicken upstairs.

Zhang Tianyi found the yellow paper and incense candle again, lit the incense candle, and then soaked the yellow paper in the chicken blood, and after the yellow paper was completely dyed red, Zhang Tianyi took out the black wood again, and wrapped the black wood with yellow paper soaked in chicken blood.

When the black wood came into contact with the yellow paper, Zhang Tianyi smelled a foul smell emanating from the black wood, and a wisp of white smoke came out, Zhang Tianyi's heart sank, and he put the wrapped yellow paper on the ground.

Then he used the remaining chicken blood to start carving the magic circle of the "bridge method", and after painting, Zhang Tianyi poured the remaining snow on the remaining yellow paper, and then lit the yellow paper with a candle flame and burned it all the way along the formation.

Under the light of the candlelight, the yang qi accumulated in the formation poured towards the black wood wrapped in yellow paper, and then submerged into the black wood, the true qi in Zhang Tianyi's body turned, the eyes of heaven opened, and a black line emerged from the yellow paper, and then floated towards the window.

Seeing this, Zhang Tianyi's heart moved slightly, and he controlled the yang qi in the formation with true qi, and then guided these yang qi to chase along this black line.

Zhang Tianyi didn't know where the yang qi went, but the ultimate goal must be the person who used this piece of black wood and performed the yin poison method, the yang qi in the rooster's blood is very abundant, if it is just a person who practices yin qi in general, he will only feel very uncomfortable, and within a few days, he will not be able to exert any yin qi.

However, if it is a person who has cultivated Yin Qi to an extremely deep level, under the effect of Yang Qi of rooster blood, the Yin Qi in the body will quickly explode, igniting Yin Fire and burning others to charcoal.

This is also an important reason why Zhang Tianyi chose the bridging method, because what kind of effect the bridging method can achieve in the end is not to see how powerful the caster is, but to see how high the level of the person receiving the law is.

For example, the better the opponent's yin qi is practiced, the more powerful the bridging method will be, and if the opponent is just getting started, the impact will be almost negligible.

People who practice yin qi have never been good people, these people, in order to absorb more yin qi, can do anything, digging people's ancestral graves, and they are relatively moral.

Some people will even go to some pregnant women, and then cast a spell to plant yin seeds in other people's fetuses, so that as the fetus grows, the yin qi will also grow, and when the fetus is born, the child will be like a ghost baby, filled with rich yin qi.

Such a child is naturally abnormal, full of diseases, and the hospital has no way, at this time, the person who planted yin reappeared, and absorbed all the yin qi on the baby's body, and the baby did not have any problems on the surface, and the symptoms of the body would soon get better.

However, children who have been planted with yin will have a very short lifespan, because they have been affected by yin qi from the beginning, so their lifespan is very short, and children cannot develop like normal people, most of them are deformed.

This method is very vicious, but it can help people who practice yin qi to quickly accumulate a large amount of yin qi, and planting yin at a time is equivalent to ten or twenty years of penance, so even if such a method is used, most of the time the person who performs it will be punished by heaven, but there are still many people who do it.

After the spell was cast, Zhang Tianyi used the leftover things of the rooster to make some feng shui changes to Fan Lingling's house, because it was an old community, and Fan Lingling's house was in a relatively remote place, and there were tall buildings on both sides blocking the light, so Fan Lingling's house was relatively dark as a whole, and such a house was not good for people's bodies and lives if they lived for a long time.

After making some changes, you can guide part of the yin energy in the room out, and then absorb some more yang energy to form a balance of yin and yang, Fan Lingling is not a big boss, and there are no relatives at home, so you don't need those fortunes, the feng shui pattern of gathering blessings, as long as you are in good health, everything will be fine.

After doing all this, Zhang Tianyi was almost tired, he consumed a lot of yang energy in Xu Ruoyan's house, and now the effect is gradually revealed, and his physical strength and energy are beginning to be a little exhausted.

However, he also has a big rooster, stewed and drank soup, it just so happened that Fan Lingling could also make up for it, and after dinner at night, Fan Lingling's house only had one room, Zhang Tianyi had no choice, so he could only sleep on the sofa.

Thinking that one day he was going to Baolingzhai to meet the other party, Zhang Tianyi did not dare to slack off, continued to condense his true qi, and cultivated the "heart cultivation technique", the more he came into contact with this profession, the deeper he understood, the more Zhang Tianyi felt that the role of true qi was very huge.
