Chapter 691: Mass Upgrade

Lin Qiao thought that the old man's throat and vocal cords could be fixed when he entered level-six, but that didn't happen.

Xie Dong, the middle-aged male zombie, the zombie boy, and zombie number six had also become zombie kings. However, none of them could talk.

Lin Qiao rubbed her chin, trying to figure out why. Would they be able to talk when they entered level-seven, like what happened to Yun Meng? Why was Liu Jun able to talk at level-four?

Was it because of Viney's power?

Lin Qiao had saved Lu Zhuofeng's energy nuclei. She planned to absorb that nucleus together with Viney when the latter was awake. However, Viney's sleeping time became longer and longer. Recently, she showed no sign of waking up.

She couldn't absorb any energy when she was asleep.

After upgrading a large group of high-leveled zombies, Lin Qiao felt a little tired. The result was good though; it was worth the hard work.
