Chapter 638

"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.

"Well, why do you think I let you here?" Xiu's voice was almost imperceptible with a smile.

"But plant three plants here. What do the demons eat?" Shen Yanxiao hesitated. She was not sure where to plant the three plants.

"It doesn't matter. Planted here, the array will send three plants to grow, and the dark elements produced by them will also be spread to the whole sun by the array, which can not only strengthen the walls, but also supply the demons."

"Hey, so good? That's settled! " Shen Yanxiao doesn't hesitate to take the three plants out of the ring. The basement is very hidden. If it's not for the repair guide, she can't find them at all. It's safe to plant the three plants here.

These three plants are very important to Shen Yanxiao. They are not only related to her survival in the barren land, but also to her future seal contact.

"After the array is opened, the dark elements will be fully activated here. The dark elements will help the demons to evolve, and the characteristics of the demons' bodies will also intensify the changes of the dark elements, and then I can recover my strength at a high speed." Hugh explained everything.

But one thing, Xiu didn't say.

That is, once the array is opened, the surging dark elements will quickly spread, and soon attract the detection of demons around the sun. Those demons stimulated by the dark elements will enter the sun in large quantities.

Will three plant seeds properly, Shen Yanxiao looked at the side of the dark crystal asked: "then how to deal with this?"

"Put it here, the dark elements here will slowly supplement the dark elements lost by the dark crystal, and then you can use it to strengthen other cities."

Reinforcement Other cities!

Shen Yanxiao blinks. Indeed, as long as she has completed the construction of the sun, she can expand towards the surrounding cities.
