Chapter 290: Two New Seven Stars Knives

Lin Zhen spent another full day cultivating the power of the flame.

After he absorbed all the A-level variant crystals, the flame within him was completely resonated.

Once the resonance was complete, Lin Zhen snapped his fingers, and a bright red flame jumped in his palm.

"The temperature of this bright red flame has exceeded 700 degrees. It is almost enough for basic infusion, but its competitiveness in the market is still not strong. Next, I have to absorb the S-level crystals and further enhance the power of both ice and fire."

This time, Lin Zhen invested a lot, spending a whopping 50 billion in just two days. He has already taken out another 50 billion, after all, S-level crystals are not common goods.

After three more consecutive days, Lin Zhen absorbed a large number of S-level crystals, almost clearing the market of its crystals. His ice-fire power finally made significant progress.

With regards to ice, he had already mastered temperatures down to negative 100 degrees.
