Chapter 638 (1/2)

”This is the dark crystal buried in the ground when the demons built the city. Only the demons can have this crystal. There are a lot of dark elements in it. This dark crystal is placed here. You can start the array in this room and reinforce the walls of the whole city. In terms of your current siege weapons, it's a three or five-year attack on the strengthened walls In ten years, there is absolutely no crack. ”

”So Against the sky? ” Shen Yanxiao's eyes widened, and the intelligence of the demon family was really amazing.

”But I think the walls have been destroyed a lot before the sun never sets. It's hard not to believe that someone has been bombarding them with artillery for hundreds of years?”

”It was made by the siege weapons of the Protoss.”

”The siege weapon of the Protoss.” Shen Yanxiao is fascinated. The protoss has fallen for a long time. It's almost impossible for human beings to have the siege weapons of the Protoss. That is to say, if she opens this array, the sun will never fall and become a real city!

Shen Yanxiao took a deep breath and said, ”this dark crystal, can you open the array?”

”No, the dark elements in it have been consumed.”

Shen Yanxiao wilted in a moment

Isn't that funny!

Watching the world's first protective cover, but can not start, her heart is broken!

But next second, Xiu's words made Shen Yanxiao excited again.

”But the three plants in your hand can activate it.”

”Really?” Shen Yanxiao said excitedly.
