The familiar upgrade panel appeared before our eyes, and it looked very clear at the moment.

"Is it promoted?"

A line of subtitles appears.

Chen An did not hesitate and directly chose OK.

Two points of source power were immediately deducted.

A warm current surged into the body, rising from the heart, then rising throughout the body, and finally gathered in the fists.

Chen An watched the changes in himself.

As the Sea Sand Fist was promoted, a layer of calluses visible to the naked eye developed on his fists, and then the color of his skin gradually darkened, making him look swarthy.

He already has some looks like the people from Haisha Quan before.

Of course it's not very obvious.

This characteristic is not exclusive to Haisha Boxing. Many boxing techniques will cause such marks to appear on the fists. It is not a strange thing.

This is also the reason why Chen An feels confident to improve Haisha Quan.

“It can continue to improve.”

Chen An took a look at the remaining source power, and then continued to choose to upgrade.

boom!

A burst of heat surged from the body, and then exploded in an instant.

At this moment, the familiar feeling flooded into the body again, and it was much stronger.

Chen An's arms began to tremble, and scenes of practice experiences flooded into his mind, deepening Chen An's understanding of the boxing technique of Haisha Fist.

This feeling lasted for a breath or two before stopping, and finally calmed down slowly.
Chapter completed!
