After the test, Wan Xiang couldn't confirm Ling Yun's true identity, and the doubts in her heart still existed. But there was no reliable way to do it other than a blood test, so he had to give up for the time being.

After all, Ling Yun, as the best of the disciples of the same class, only needs to cultivate carefully, and he will definitely be able to achieve something in the future. Outstanding disciples should have been treated with a tolerant attitude.

Although Ling Yun failed the test, she was able to escape because of the intrusion of Zhao Yangtian and others. Afterwards, the group of them was listening to Taolou to discuss the matter.

"Master, the book says that the identity of a person of the Wu Clan can be determined by blood alone, why does Master Wan still use the Lich Stone?" Qianyu expressed puzzlement.

Zhao Yangtian said: "It is better to believe in a book than to have no book, and you can't believe everything in the book." Times are changing, and what is recorded in ancient books was correct at that time, but it may be wrong now. Take the question you just mentioned as an analogy, nowadays, the blood of some people of the demon clan is also purple, which is not much different from the color of the blood of the people of the witch clan. The Lich Stone, on the other hand, can identify the blood of different races, and it is relatively accurate. ”

"Elder Zhao, is there really something wrong with the Lich Stone of Master Wan? Why is everyone's blood purple? Also, what is that blue grass you just let us eat?" Silly Qiang asked, this is exactly what everyone wants to know.

Zhao Yangtian smiled mysteriously and said, "Fortunately, I have made preparations in advance, otherwise I am afraid that I will be in a catastrophe today." In fact, there was nothing wrong with Xiangxiang's Lich Stone, and the results it came out were correct. ”

"But we're not from the Wicans. Liu Yiyi felt very puzzled, then thought about it, and suddenly said, "I know, it must have something to do with the blue grass that Elder Zhao gave us to eat." ”

Zhao Yangtian smiled with satisfaction and said, "That's right." To explain to you what happened today, we have to start with how the Lich Stone works. ”

"Do you know chemistry?" Zhao Yangtian looked at everyone, and everyone was at a loss, unable to understand the meaning of this word.

Zhao Yangtian paused for a moment and said, "I'll try to explain it in a way that you can understand." Lich stone contains many trace amounts of chemical elements, tentatively named one, two, three...... and so on, and the blood of each ethnic group also contains trace amounts of chemical elements, which is temporarily named one two or three...... Wait. When one of the Lich Stones meets one in the blood, it will produce a wonderful chemical reaction, and the external manifestation is that there will be a noticeable color change on the Lich Stone. ”

"The blood of different races contains mostly the same elements, but each blood contains its own unique trace element, and when this trace element comes into contact with the trace element in the Lich Stone, a unique color reaction occurs. Do you understand?"

Except for Xu Qiuyun, everyone else was confused, as if they were listening to a wordless heavenly book.

"You're stupider than I am, it's the simplest of things, and you can't understand it when you explain it so clearly. Zhao Yangtian complained, and then said: "The blood of the human race and the Wu clan is extremely special, the elements they contain are almost the same, the only difference is that there is an extra element in the blood of the Wu clan, which I call "zero". ”

In other words, as long as you add "zero" to a person's blood during the test, the result of the test will be the same as the blood test of the Wu people. "Qianyu kind of understood.

"The child can be taught. Zhao Yangtian cast an appreciative look at Qianyu, "I have been looking for thirteen years, almost all over the continent, and finally found a small blue grass in the jungle of the Southern Wilderness, which contains a large number of "zeros". That's why I let you eat grass. ”

"When you eat grass, the "zero" gets stained on your teeth. When we bite our fingers with our teeth, the "zero" enters our bloodstream, and our blood will appear purple when tested. Qianyu explained for Zhao Yangtian.

"Yes, this is the most crucial step, and if you don't bite your fingers with your teeth and cut them with knives, the plan will fail. Zhao Yangtian was also a little nervous at the time, for fear that Wan Xiang would see the flaws. Fortunately, Wan Xiang was frightened and paid no attention to this.

Xu Qiuyun said: "This is a palliative but not a cure-at-all method, and it won't be long before Wan Zhangmen will see through it." The imperative is to come up with a long-term solution. ”

Zhao Yangtian said: "I have already planned, this time the apprentice will go to the Hidden Dragon Empire, Ling Yun will go together, no matter whether the apprentice succeeds or fails, Ling Yun will not return to the Thousand Moon Cave Heaven." ”

As soon as these words came out, Qianyu and the others were a little surprised, Ling Yun's expression did not change much, obviously she had planned to do so a long time ago.

"Xiangxiang is a smart person, this matter can't be hidden for long, the sooner you leave, the better. Zhao Yangtian said with a solemn expression.

"Separations always come so suddenly. Qianyu was a little reluctant, and Ling Yun's pretty face also showed the same look, she has lived here for five years, there are friends who accompany her, there are teachers who teach her, and there are boyfriends who have a deep relationship with her...... A flower, a grass, a tree and a stone, this place has long become the second home of her spiritual career.

When the Wu clan bloodline in her body broke out for the first time, Zhao Yangtian made a plan for her to leave. She thought that when it was time to leave, she would leave without hesitation, but she didn't expect that she was still full of reluctance and attachment at this moment.

Leaving the Thousand Moon Cave Heaven, where should she go?

"Adaptable. This is Zhao Yangtian's advice to her.

Then, Zhao Yangtian looked at Qianyu and said, "Apprentice, in a few days it will be Duan Yuming's enthronement ceremony, you can leave when you are ready." Remember, this is your only chance. Success, not failure!"

"Hmm. Qianyu replied with a serious face.

"Silly Qiang, Liu Yiyi, you two stay here. "Zhao Yangtian wants to cut off all of Qianyu's retreats, so as to stimulate Qianyu's fighting spirit.

"Elder Zhao, I will go wherever the boss goes. "Silly Qiang wants to go with Qianyu.

"Absolutely not. Zhao Yangtian categorically refused, "If there is a need to make a move, I will protect him thoroughly, you don't have to worry." ”

With Zhao Yangtian's escort, the two of them immediately put their minds at ease, and then said goodbye to Qianyu and Ling Yun respectively.

Liu Yiyi and Ling Yun are best friends, and now that they are facing farewell, the two can't help but feel a little sad, and they can only help each other to be okay and have a bright future.

Silly Qiang and Qianyu were only separated for a short time, and Silly Qiang didn't have much to say about this, the only thing that came to mind was: "Boss, remember to help me bring a lot of delicious food back, hehe." ”

"I'll bring it to you if it's convenient. "Qianyu's priority is to defeat Duan Yuming, as for other things, they can be put aside for now, and then they can be done when they have time.

After agreeing on where to go, Qianyu planned to find someone - Yi Chen.

Yi Chen's cultivation is comparable to Duan Yuming, and he is also a rare genius on the way to cultivation. Qianyu didn't know what his current cultivation was, so he just asked Yi Chen to test it.

"Brother Qian, long time no see. Yang Xiu came to the door at this time and greeted Qianyu warmly.

Qianyu returned the salute with a smile: "Brother Yang?"

"It's three years in a blink of an eye, and time waits for no one. Yang Xiu said with a greeting.

Qian Yu smiled and waited for Yang Xiu's next step.

Yang Xiu said: "In six days it will be Duan Yuming's birthday, and he sent me an invitation. I heard that there are some contradictions between Brother Qian and him, so it is better to take advantage of this banquet to completely solve the matter with him. ”

Qianyu wanted to refuse and go alone, but after thinking about it, he didn't have an invitation, and it was difficult to enter the imperial city under heavy guards. With Yang Xiu's help, you can save a lot of trouble. So, he agreed to Yang Xiu's suggestion.
