After that, Xiao Tian pauses, and then tells Xiao Li and others the formula of "Tian Lei Yin".

Xiao Li and others quickly calm down and write down the pithy formula of "Tianlei Yin"

"this fighting skill is extensive and profound, which can arouse the power of heaven and earth, and may have reached the level of heaven." after listening to the pithy formula of "Tianlei Yin", the medicine dust just pondered it and exclaimed.

"It's not a heaven level fighting skill," Xiao Tian said with a smile when he heard Yao Chen's words. "Seriously, this fighting skill can't even be regarded as a low-level skill. After all, this fighting skill relies too much on external forces."

This "Tian Lei Yin" is a fighting skill formed by his modification of the secret secret secret secret of the Qingyun gate.

He himself is not very optimistic about this fighting skill, because the sky thunder guide relies too much on external forces, leading to its unstable power.

If you can attract jiuxuan Jinlei and other levels of robbery thunder, you will naturally have no fear of the vast majority of experts on the mainland. But if only ordinary thunder is triggered, then you can only bully the weak people below douzong.

However, in the eyes of Yao Chen and others, such a fighting skill is already mysterious. Before that, only Lei clan could borrow the power of thunder on the land of fighting Qi.

Moreover, the Lei clan only used the force of thunder to refine themselves, attract the force of thunder and fight against the enemy. This is the first time that Lei clan appeared on the mainland!

In particular, this fighting skill can ignore the threshold. No matter how powerful the thunder is, it will not bite back at the performer.

That is to say, if the force of thunder is strong enough, it can even cross multiple realms to fight the enemy!

"OK, don't say this," Xiao Tian waved his hand, looked at Xiao Li, and asked, "how much did you write down?"

"Back to the teacher, all the students have written down," Xiao Li quickly replied.

"That's good," Xiao Tian nodded and said faintly, "you only have three days. In three days, if you can understand Xiaocheng, then no one can stop you in Yunlan sect except Yunshan mountain."

"I understand!" Xiao Li nodded seriously and said in a deep voice, "I will not let the teacher down!"

While speaking, Xiao Li's eyes flashed a startling killing intention.

Obviously, what yunlanzong did this time also made the second young master of Xiao family really angry. Otherwise, the second young master of Xiao family, who was called "cunning fox" by good people in Tagore desert, would not have made such impulsive decisions!

"All right, go ahead. Send someone to tell me before we set out," Xiao Tian waved his hand and said faintly.

"I'll leave," Xiao Li said no more, and said respectfully to Xiao Tian.

With that, Xiao Li cast his eyes on Hai Po Dong and said seriously, "Lao Hai Lao will be pressing for me for a period of time."

"It's just a little thing. Don't take it to heart," he said with a smile.

Xiao Li no longer tangled with his words, turned and ran in the direction of Xiao's house. Haibodong saw his figure and quickly followed him.

After Xiao Li and Hai Botong left, Xiao Tian had no time to speak. The cold and mechanical voice of the system suddenly sounded in his mind --

"Ding! Congratulations to the host for triggering the special task "battle of yunlanzong". Please check the details by yourself. "

Hearing the system prompt, Xiao Tian picked up his eyebrows, but his expression did not change at all. He looked at Xiao xun'er and said, "if you want to see the fun, you may as well follow along. However, except for Xiao Yan, you can't do anything until life or death."
