I'm covering this boss soon

Chapter 908 Mary Su Cultivation 94
Everyone thinks so, even Yun Rong thinks so at the same time.

"Junior Sister Bi, admit defeat."

Bi Siyu looked solemn, "Brother, if you want to win against me, this alone is not enough."

Yun Yan frowned slightly, he was merciful because she was a brother and sister of the same school, but he didn't expect her to be ignorant of good and evil.

"Since this is the case, don't blame the senior brother for making a heavy hand."

"Just let the horses come."

Yun Yan made an overwhelming move, defeating her was enough.However, an astonishing scene happened on the field. Bi Siyu's aura surged, and traces of silver lightning appeared around her body.

The elders of all factions stared wide-eyed, several elders of Yinxianzong and Xuan Qingzi looked at her in disbelief.

"Heavenly Thunder Transformation." Following her stern shout, countless thunder and lightning surged towards the cloud like a surging tide.

Yun Yan was stunned, seeing the attack approaching his eyes, he immediately mobilized the spiritual power of his whole body to block her attack.

"Bang bang"...

I saw Yun Yan's body floating high, falling heavily, and passed out directly.

All of this happened so fast that many monks didn't even realize it, and it was clear that Yun Yan, who was optimistic before, would be defeated.

"What kind of trick did she just use, it seems very powerful."

"What seems to be very powerful is very powerful."

"Does anyone know what spell that is?"

"Why do I feel like she's using the Lightning System's technique?"

"I remember that Shadow Immortal Sect has a skill called Thunder God Jue. Could it be Thunder God Jue?"

"It must be the Thunder God Art."

The seats where the disciples of the Shadow Immortal Sect were no less shocked than the disciples of other sects, it can be said that they were even more shocked than other sects.

"This is the legendary Thunder God Art."

"Didn't you say that only mutated Thunder Spirit Roots can cultivate? Let me go, Bi Siyu is actually a Thunder Spirit Root. Don't tell me she is a miscellaneous Spirit Root of the fourth element, why did she suddenly become a Thunder Spirit Root?"

Immediately someone said: "She must have taken the marrow washing pill to wash away other miscellaneous spiritual roots. She was very lucky to encounter the legendary mutation."

Everyone knows the effect of Xisui Pill.

Some people can wash off two or one, and if they are lucky, they can wash off three or four, which is very rare, and the spiritual roots that become mutants are even more legendary.

No one thought that one day they saw the legendary mutation of marrow washing.

"She hides so deeply."

"It's no wonder that she cultivated so fast. I didn't expect her to be a mutated Lei Lingen."

Many people noticed her unusualness before, and some even wanted to find out if there were any natural treasures in her that prompted her to cultivate so quickly.

Now the answer is clear!

The referee announced: "Bi Siyu succeeded in the challenge and became the champion. Who will challenge on stage?"

Hearing the referee's words, many people were eager to try, and many of them were defeated by Yun Yan.

"I."

A hulking man jumped onto the ring first.

"Let me teach you the Thunder God Art of Shadow Immortal Sect."

The man's speed was very fast, and he started to fight as soon as he came up, and Bi Siyu reacted very quickly.

After fifty rounds, the man was defeated.

"I didn't expect her to be so strong."

"Before I challenged by two levels before, I thought it was Yun Yan's carelessness. Now it seems that she has this strength, and the Thunder God Art is really extraordinary."

When Bi Siyu heard the words of the people around her, the corners of her lips rose slightly.
