Refining essence into qi, refining qi into spirit, refining spirit to return to emptiness.

Easily change bones, tendons, and marrow.

That's all correct.

Internal martial arts do not involve external training.

When the marrow is full, the bones are hard, and the bones are like iron rods.

His muscles were bulging, and his fists were like leather hammers.

Gradually, an inner lining grows inside the body.

Then it can withstand the blow.

These are the foundation of internal martial arts.

The first step is always to refine essence into qi.

Higher bone density means heavier and stronger bones.

Weight gain also leads to a greater impulse.

His physical appearance may not have changed, but his bone density has changed, and his body is full of tightly packed flesh, so his ability to withstand blows is naturally stronger.

A fist on someone is like an iron rod poking them.

Could an average person handle that?

"If you're not going to attack, then I'll go for it!"

Yuan Yi watched as Zhang Dabing simply circled around him without making a move.

Seeing that he still didn't move, Yuan Yi charged forward with his fist raised.

Xingyiquan was originally called Xinyi Liuhequan, which means the mind and intention are in harmony, intention and qi are in harmony, qi and strength are in harmony, shoulders and hips are in harmony, elbows and knees are in harmony, and hands and feet are in harmony.

He went up and delivered a powerful, heavy chopping punch.

Zhang Dabing hadn't paid any attention to Yuan Yi, thinking he was just a pretty face.

He raised both hands to block it.

But as soon as he touched it, he knew something was wrong.

He immediately used his hard qigong to block it, but unfortunately it was too late.

Yuan Yi's single chopping punch sent Zhang Dabing's body crashing down, his legs buckling and nearly causing him to kneel on the ground.

The moment they made contact, Yuan Yi had already withdrawn his strength.

Otherwise, Zhang Dabing's hands would have been crippled by now.
