It turns out that the Nine Yin Absolute Veiners have had a difficult time cultivating since birth, and as they get older, the cold poison that occurs every month increases month by month.Cold poison accumulates in the body year by year, eroding and blocking its meridians until the meridian roots are broken; At the same time, it erodes and destroys its spiritual roots until the spiritual roots wither and disappear; It will make its dantian fragile and fragile, and it will shatter when touched until one day the dantian is overwhelmed and completely collapsed.At this time, those who suffer from the Nine Yin Absolute Veins will be frozen into ice sculptures by the cold poison in an instant and die, and after death, the body will not be destroyed for thousands of years.Its frozen ice sculptures are comparable to the thousand-year-old ice of a dangerous place.It is a treasure that many low-level monks rush to compete for.Thinking of this, Yun Yueyao couldn't help but imagine that when the demon turned into an ice sculpture in her previous life, she didn't know how many low-level monks would snatch it, and she didn't know how many female cultivators would want to take it for herself and fight it.Tsk tsk, that demon's face must have made the female cultivators in the immortal cultivation world break their heads, in fact, how Yun Yueyao committed suicide before that, of course she didn't know.After the Heavenly Peerless Dao was reborn with her, he didn't see the follow-up, and of course he didn't know.If Yun Yueyao wants to carry out blood exchange, she must first carry out a series of tempering and transformation of the prince's body.Increase its bearing capacity and exuberant its vitality.In order to carry out the blood contract, and then to exchange blood.As we all know, ordinary mortals have scarce essence blood on their bodies, and after condensing through secret methods, the blood of the whole body can only be refined into a drop of natal essence blood, with a slight trace of golden light in the red.The monks below the foundation building period are only about one and a half drops.When the essence and blood are separated from the body, people are more than dead.This drop of essence and blood condenses the essence of all a person's essence, qi, and blood.Under normal circumstances, it is impossible to directly take human blood, which is equivalent to seeking human life.However, the secret technique of blood exchange in the Nine Yin Spirit Recipe can use the blood contract to connect the lives of the two people and achieve a short period of living and dying together.During this period, take out the other person's essence blood and fill your own essence blood into the opponent's heart.That is, the exchange of blood, and the person who has been taken sperm blood will be safe and sound.Moreover, the benefits of this secret technique can increase the amount of essence blood on both sides, for example, Yun Yueyao has three drops of natal essence blood at this time.This is already the limit of today's cultivation.If you want to make more essence blood, you must build the foundation after the period.And the night is cold, there is only one drop like a normal person, and after Yun Yueyao condenses, the essence blood that is taken away will be the same as Yun Yueyao's, and it has the effect of devouring cold poison.After Yun Yueyao returned it to him, she wanted to take back a drop of her essence blood, and at the same time take blood from him for condensation.In this way, until the three drops of essence blood are exchanged back, Ye Qinghan will also have three drops of natal essence blood like Yun Yueyao.At this time, Yun Yueyao didn't know that after improving the other party's body and blood contract, there were many wonderful uses.And one of them is double cultivation.When she finds out in the future, I don't know how she will feel Yun Yueyao concentrated on transforming her body for Ye Qinghan, and she also tried her best to succeed in the blood exchange.Several times when her spiritual power was about to be exhausted, she grabbed a large handful of pills and threw them into her mouth, and then supported them with spiritual spring water.Unexpectedly, he insisted on the sixth layer of the gas refining period.Until she washed away the number of seven, seven, four and nine of the strange meridians and dantian of the cold night.That is, forty-nine days of operation, only then stop, change the trick, and prepare to enter the next step of the blood contract 46xx4911131
