After the maid left, Wang Ou came to the window, gently pushed the window open, and the bright moonlight sprinkled in.

What happened today was uneasy for her. She had to start thinking about how she would face the problem if it came to light.

Cui Yuzheng, she is not afraid to face it. Although Cui Yuzheng said that she owed him, Wang Ou didn't feel so in her heart, she didn't owe Cui Yuzheng. There is no affection between her and Cui Yuzheng, and the relationship between the two should be a symbiotic relationship to be precise. Because of the poison of the snake spirit, her life and Cui Yuzheng's lives are connected, if she dies, Cui Yuzheng will also die, and if Cui Yuzheng dies, she will also die. In such a relationship, who owes whom?

And what Cui Yuzheng said, the so-called debt, is a long story.

Everyone in the world knows that Cui Yuzheng, the eldest grandson of the Cui family in Qinghe, has been frail and sickly since he was a child. But I don't know what the reason is, and even many people in the Cui family don't know, and only a few people know the truth.

The snake spirit has been inherited for thousands of years, and the sect is all over the world, and among the gate valve families, there are naturally people who believe in the snake spirit. Cui Yuzheng's mother is a fanatical believer in the snake spirit. There is a legend among the snake spirits that when she was pregnant, she fed the snake with blood, and then let the snake bite herself, so that the snake venom entered the body and poisoned herself. If the snake venom of the snake raised with sperm blood can be carried through, the fetus born will have the ability to be invulnerable.

And this ability is a prerequisite for the snake spirit to choose the sect leader.

In order to make her son the leader of the sect, Cui Yuzheng's mother risked her life and adopted this secret method. But maybe it was because her secret method was incomplete, or maybe it was not done properly, she didn't succeed, or she didn't succeed completely. After Cui Yuzheng was born, he did not get the physique of 'invincibility'. On the contrary, because toxins accumulate in the body, resulting in weakness. And Cui Yuzheng's mother also died when Cui Yuzheng was seven years old because of snake venom residues.

But this is not the end, Cui Yuzheng's mother was not discouraged by failure, her fanatical belief made her still study the secret method of snake spirit in the seven years of postpartum snake venom and suffering. She was convinced that she couldn't go wrong with the secret method she had gotten. Since it didn't achieve the desired effect, it would be nice to do it again, do it again!

So, in the past seven years, Cui Yuzheng's mother raised a snake with her own blood, and before she died, she instructed Cui Yuzheng to continue to raise, Cui Yuzheng was already a little fanatical believer under the cultivation of his mother, and after his mother died, he continued to raise the snake with his own blood.

In the secret method of the snake spirit, such a snake is called a life dragon.

The snake has to drink blood several times a month, and Cui Yuzheng's body naturally does not get better under the condition of long-term blood loss and poisoning. But the emperor lived up to his wishes, and finally, when Cui Yuyan was sixteen years old, when he was sucked by snakes, he couldn't feel the influence of snake venom at all, and he knew that he had succeeded, and he was already invulnerable.

But his poison invasion came too late, and his body couldn't bear it anymore. His life is coming to an end.

Just as the time limit for the snake spirit's sect leader was approaching, he sent the snake slave to find a suitable heir. Cui Yuzheng's physique passed the test, and although he was about to die, he was also listed as one of the candidates.

At this time, it was the time when the Cui family was happy and married Wang Ou.

The day after the two got married, the snake spirit sent someone to pick up Cui Yuzheng. Although Cui Yuzheng knew in his heart that he had no hope, his obsession with living for seventeen years was for the sake of the snake spirit, and even if he died, he wanted to see it.

He didn't want the snake spirit to involve the Cui family, so he begged his daughter-in-law Wang Ou, who had just passed the door, and begged her to take him. And promised that if she took it with her, he would give her a letter of resignation, and after his death, Wang Ou would be free.

The temptation of freedom was really irresistible for Wang Ou at that time. After a short period of hesitation, Wang Ou agreed to Cui Yuzheng's request, carried the Cui family on his back, took Cui Yuzheng out, and participated in the ceremony of the snake spirit.

It was this ritual that changed the fate of two people.

The reason why the snake spirit is called the snake spirit is that according to legend, there is a spirit snake. But no one has ever seen this spirit snake, some people question whether it exists, and many people believe that it must exist.

When Wang Ou heard Cui Yuzheng talk about it before, he didn't believe it very much. But after attending the ceremony that day, she believed it, because she saw it. A small snake, or rather a light, a line, extremely thin, extremely small. This thing came out of the body of the previous sect leader, like lightning and flint, drilled into the bodies of all the candidates, Wang Ou saw with his own eyes, one by one, the living people bled to death.

In the end, only she, Cui Yuzheng, and the former sect leader who only had one breath left.

As the thin line of light left the body of the previous Master, the former Master shriveled up as if he had lost all his life, his hands were as thin as hemp stalks, his skin was covered with bones, and his skin was cracked, looking like a skeleton.

He looked at Wang Ou and Cui Yuzheng, who were still alive on the ground, and his eyes were full of shock.

The person chosen by the snake spirit turned out to be Wang Ou, but Wang Ou did not have the blood that was invincible, so she couldn't give the snake spirit a 'boarding' environment. Therefore, she is now highly poisoned and is about to die.

And Cui Yuzheng was not chosen by the snake spirit, but he didn't die either. Because his 'invincible' body has undergone double beating. He carried one in his womb, and after he was born, he condensed it for another sixteen years, and his poison was invincible, and he was better than his competitors, so that the snake spirit drilled through his body, and he did not die of anger.

The Snake Spirit Sect Master, who was about to die, was faced with a situation he hadn't expected at all. He is going to die, and the snake spirit chose a person who does not have a hundred poisons to invade the body as a host, this person is also going to die, the person who has a hundred poisons does not invade the body, the body is weak, not to mention that the snake spirit did not choose him, even if he chooses, he will not live long. And the snake spirit has no host, and it will soon die, and the snake spirit that has been inherited for thousands of years is about to be destroyed in his hands.

This must not be allowed to happen! The Snake Spirit Sect Master hurriedly took a pill, his shriveled body returned to light, and he regained his vitality again, cut Cui Yuzheng's blood vessels, and released a bowl of blood, he used this bowl of 'poison does not invade the body' blood, combined with countless precious medicinal materials, condensed a pill, he didn't know if this pill could work, and now, he could only be a dead horse as a live horse doctor.

The pill was given to Wang Ou, but fortunately it worked, the snake venom gradually subsided, and the snake spirit gradually stabilized. Just as the Snake Spirit Sect Master was relieved and was about to go back to the 'Holy Altar' to die, he suddenly realized that it was too early to rejoice!
