There was a huge hand on the building, and everyone was confused about what was going on.

Before they could see clearly, a hand suddenly slammed down on the building, instantly shattering the top of the skyscraper. A loud boom followed, and in an instant, the giant hand razed the building to the ground.

By the time the smoke and dust blew over, the mercenaries still had no idea what was going on.

On another building, Lu Chengchuan had put down his hands and looked at the flat ground. He nodded with satisfaction.

A building more than forty stories high was reduced to dust from the top to the first floor.

After seeing the effect of the palm strike, Lu Chengchuan opened the system panel again. Now he has a lifespan of 500 years and can improve his martial arts.

The third level of the Soul-Capture Technique requires a lifespan of three hundred years, and it will not be upgraded for the time being.

The rest are the shrinking technique and the shape-shifting technique. Lu Chengchuan also discovered that after breaking through to the realm of spirit refining, it only takes half of the previous lifespan to improve Xuan-level martial arts.

Originally, it would take one hundred and twenty years of life to complete the Shapeshifting, but now, it only takes sixty years.

This was a surprise, and Lu Chengchuan upgraded his Shapeshifting to perfection without hesitation.

There are three levels of shrinking skills, and it takes 720 years to reach the perfect state. Lu Chengchuan looked at it for a while and then turned his attention to other martial arts.

Five Xuan-level martial arts can be integrated into one Di-level martial art, which can be internal or external skills, as long as the number is sufficient, they can be integrated, but he is still missing one Xuan-level martial art.

But martial arts like teleportation and shrinking the earth don't work for him, so he has to go find another martial art.

"It's time to go back."

Lu Chengchuan couldn't wait to go back and find another Xuan-level martial art.
