"Okay, come with me." For students like Mu Feng who have clear goals, middle-aged people generally don't talk nonsense and directly took Mu Feng toward the earthquake zone.

After about twenty minutes, I arrived.

"Here, you go in. I'll be at the door. I'll call me after choosing and I'll take you away." The middle-aged man walked over and stretched out his hand and gently pushed open a heavy iron door, allowing Mu Feng to walk in.

Mu Feng tried it himself, and he couldn't push it at once. You know, his push now has at least 30,000 kilograms.

"This iron gate weighs 50,000 kilograms. If you don't have eight levels of cultivation, you can't push it."

Mu Feng was slightly surprised. Just now, the middle-aged man just reached out and pushed the door open. The middle-aged man's cultivation level was at least eight levels.

So awesome!

It seems that this middle-aged man is just a guardian of the Sutra Library, and he is so powerful.

The foundation of Bai Qi Academy is really unsatisfactory.

"If you can promote this iron gate, I can make the decision to let you choose another martial art for free." The middle-aged monk suddenly said.

"Senior?"

"certainly."

Mu Feng exhaled slightly, and the true energy in the dantian was poured into his arms like surging waves, and suddenly pushed towards the iron gate.

quack……

The 50,000 kilogram iron door was really pushed by him and turned inward for more than a meter.

"Yes, boy Mu, you can choose another martial arts secret book." The guardian showed a little surprise, but what he said naturally counted, giving Mu Feng an extra chance.

"Thank you, senior." Mu Feng bowed gratefully.
