This shows how powerful this third-grade holy thunder is.

After reaching the reincarnation state, Xiao Yifeng wanted to improve his physical strength.

Its level of difficulty is also dozens of times more difficult than before, and it is much more difficult than improving other realms.

Now he needs all kinds of powerful forces from heaven and earth or rare treasures from heaven and earth to temper his body.

In this way, his physical body can be strengthened to the point where he can trigger the fifth physical thunder tribulation.

And in the process of refining the Holy Thunder.

Xiao Yifeng also integrated the sky thunder in his body into this holy thunder, which greatly enhanced the power of this holy thunder.

But it has not yet reached the level of fourth-grade holy thunder.

After refining the Holy Thunder, Xiao Yifeng began to control the fourth-grade Holy Fire again.

With the help of this fourth-grade holy fire, Xiao Yifeng once again tempered his physical strength.

Let his physical body have a new improvement.

Another day has passed.

A crackling sound came from Xiao Yifeng's body.

The muscles and bones all over his body made roaring sounds.

A terrifying and heavy aura, like a mountain, erupted from his body.

Everything in the entire room was instantly turned into powder.

This is just the momentum that his physical body burst out, and this momentum is less than one-tenth of his complete physical momentum.
