Chapter 638 Building a City (9)

'This is the dark crystal buried underground when the demons built the city. This crystal is only found in the demon world, and it contains a lot of dark elements. This dark crystal is placed here to activate the magic circle in this room , Reinforce the walls of the entire city. With your current siege weapons, even if you blast the reinforced walls for 30 to 50 years, you will never be able to blast a crack. '

"So... against the sky?" Shen Yanxiao's eyes widened, the wisdom of the demons really made people admire.

"But I see that the wall has been destroyed a lot before the sun sets. Could it be possible that someone has bombarded it with artillery for hundreds of years?"

'It was caused by the siege weapons of the Protoss. '

"The siege weapons of the gods." Shen Yanxiao was fascinated. The gods had fallen for a long time, and it was almost impossible for human beings to have the siege weapons of the gods. This means that if she activates this magic circle, then the sun never sets will become the real meaning The city that never falls!

Shen Yanxiao took a deep breath and said, "Can this dark crystal still activate the magic circle?"

‘No, the dark elements in it have been exhausted. '

Shen Yanxiao froze in an instant...

Isn't this funny!

Seeing the world's number one protective cover, but it couldn't be activated, her heart was broken!

But in the next second, Xiu's words cheered Shen Yanxiao up again.

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

"Really?" Shen Yanxiao said excitedly.

‘Well, otherwise, why do you think I let you come here? ’ Xiu’s voice carried an almost imperceptible smile.

"But if the three plants are planted here, what will the demons eat?" Shen Yanxiao was a little hesitant, because she hadn't decided where to plant the three plants before.

'It doesn't matter, it's planted here, the magic circle here will make three plants grow, and the dark elements produced by them will also be spread to the whole Sunset by the magic circle, not only can strengthen the city wall, but also can supply those monsters . '

"Hey, so good? Then it's settled!" Shen Yanxiao no longer hesitated, and directly took the three plants out of the storage ring. This basement is very hidden, and if it wasn't for Xiu's guidance, she would not be able to find it at all. There is nothing safer than growing a plant here.

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

'After the magic circle is activated, the dark elements here will be completely activated, and the dark elements will help the monster evolve, and the characteristics in the monster's body will also intensify the changes of the dark elements, and then I can recover my strength at a high speed. ’ Xiu explained everything.

But there was one thing that Xiu didn't say.

That is, once the magic circle is opened, the torrential dark elements will spread rapidly, which will soon attract the attention of the monsters around the never-setting sun, and those monsters stimulated by the dark elements will enter the never-setting sun in large numbers.

After placing the seeds of the three plants properly, Shen Yanxiao looked at the dark crystal beside him and asked: "Then what should we do with this?"

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

Reinforce... other cities!

Shen Yanxiao blinked her eyes, indeed, as long as she completes the construction of the Never Set Sun, she can expand towards the surrounding cities.
