He had only learned the first level of all the skills he had learned, and hadn't yet mastered them fully. He needed to master them fully and improve them in his own palace, which was the safest way.

Lin Che stood in the yard, ready.

Ding-ding-ding-ding

The system's voices began to prompt one after another.

Lin Che's body also began to change. At first, as a few of his skills advanced, he didn't feel much. But after more than twenty skills reached the tenth level, his body began to heat up, and his internal organs felt like they were burning with flames.

Especially the qi and blood in the whole body, which has been in a boiling state and has never stopped.

Ding! Ding! Ding! Ding!

Lin Che suddenly trembled, and then his body suddenly swelled. His head grew bigger, his chest grew bigger, and his stomach grew bigger...

Crackle! The bones also made crackling sounds.

"My body has almost reached its limit!"

The entire courtyard was filled with a whirring wind, forming a visible vortex with him as its center. That was because the air currents between heaven and earth were being madly absorbed into his body.

"Not good. At this rate, the energy between heaven and earth won't be able to keep up. I need to take some pills!"

Fortunately, he had quite a few things in his hidden bag, and he could take all kinds of pills directly.

But these pills were absorbed in just a few seconds after being taken.

Lin Che simply gritted his teeth and took out a bucket of divine python blood.

Normally, he would use a drop of divine python blood to refine the elixir, which was enough to make his subordinates unable to bear it, but now he directly picked up a bucket and gulped down the drink...
