Chương 125: Dragon-Horse Spear General— Wu Xin!

After Zhou Zhou realized the importance of the Light Drawing Crystal, he immediately went to look for Zhao Changshou and showed it to him.

"Light Drawing Crystal?"

"This is good stuff."

"Its name might be similar to the Aurora Crystal but they are two completely different things."

"One is a life energy core while the other is an excellent building material."

"The Light Drawing Crystal only needs to be exposed to the hot sun for three days before it is filled with Light Element energy. It will then become the Light Origin Stone, a White Silver-Tier construction material."

"If we can mix it into the city wall…"

"Then the defense of our city wall is enough to withstand some Yellow Gold-Tier attacks."

Zhao Changshou said with surprise.

Zhou Zhou was delighted.

"In that case, I'll use the Light Drawing Crystal to replace the Sand Crystal to build the city wall in the future."

He said without hesitation.
