Even if he cannot improve his cultivation level, he will use this to consolidate his cultivation level.

Of course, this is not something that ordinary people can do. If you are to fight against the catastrophe, even if you survive the catastrophe, you will often be seriously injured and dying. Even if you are not seriously injured and dying, your vitality will be severely damaged.

However, for Li Feng, he doesn't think about it that much now. For him, as long as it is useful to him, it is enough, and nothing else matters.

Boom boom boom...

The thunder dragon roared down, each one stronger than the other. Gradually, Li Feng's situation gradually changed. The power coming from the thunder dragon became stronger and stronger, and it was difficult for him to hold on.

"Can't you hold on anymore?"

Li Feng looked at the calamity clouds in the sky with a solemn expression: "In that case, use another way to overcome the calamity. I don't believe it, and I can't survive this thunder calamity."

Rumble…

At this moment, the calamity clouds in the sky suddenly changed. Countless calamity clouds condensed, and the energy released in the calamity clouds suddenly exploded dozens of times.

"How could this happen?"

Li Feng's expression changed several times. The thunder tribulation just now was equivalent to the seventh-level thunder tribulation on the Five Elements Mountain, but now it suddenly turned into a ninth-level thunder tribulation, and it was even getting stronger.

"die!"
