Chapitre 490: The Roaring Kun

"The old chief is psychologically stable. There aren't any abnormal reactions in his body, and all data is normal," Xu Wanqing reported to Wu Mo.

Wu Mo nodded. The old chief had completed his injection of Life Second. He believed that he would soon realize the huge changes that had happened to him.

As long as the old chief's body was rejuvenated, he would have more energy to deal with the sea monster crisis!

Wu Mo told himself that this might be the time for his parents to be injected with Life Second.

There was no conflict between Life First and Life Second. Theoretically, one could inject Life Second about a month after receiving Life First.

Some questioned the value of Life First since Life Second was invented.
