บท 290: Thunder Essence Crystal

Nine days later, Yu Nianzhen and Jiang Yue arrived in the core area of the thunder forest.

As expected, the core area was extremely perilous.

The lightning was several times more powerful than in other areas and the two could barely protect themselves.

"We need to break through to the fourth level of body refining. Otherwise, we can't stay here for too long." Jiang Yue said and covered his body with a layer of fire.

The fire counteracted the lightning but he knew he couldn't keep it up.

Sooner or later, he would exhaust himself and the lightning would fall onto his body.

At that time, he would be lucky to escape with serious burns.

"Let's find the thunder pool." Yu Nianzhen said solemnly.

Similar to Jiang Yue, his body was covered by a layer of sword intent but the sword intent could only withstand a few strikes before it dissipated.

"Good." Jiang Yue agreed and the two began their search.
