Chapter 823

So I don't believe that Zhao Fengnian was killed. This is a natural cave.

That said, is it the Sun Tribe elder lied? In order to be afraid of being robbed by others?

Zhao Fengnian shook his head and said in his heart, "forget it, the spirit stone will be gone. There is no need to fight because of this."

Thinking of this, Zhao Fengnian no longer considered the issue of Lingshi, but carefully observed the surrounding environment.

Along the way, Zhao Fengnian, Zhao Fengnian and others were all attentive to the changes in the surrounding environment.

Now after careful observation, Zhao Fengnian was surprised to find that the temperature here is much higher than the ground!

You know, it's underground. The sunlight is very limited. The luminescent stone can only release light, but not heat.

In principle, such underground should be cool, even cold.

But how could it be hotter than the sun on the ground?

Then Zhao Fengnian looked around and finally looked at the huge pool the size of a basketball court in front of him.

At first glance, the pool was built by the Sun Tribe in order to collect and distribute the underground spring water.

But now there's only a thin layer of water in this pool, and it's bubbling.

Seeing here, Zhao Fengnian knows that the reason why the temperature here is so high is entirely because of this hot spring.

Yes, this should be the natural hot spring, the underground water source mentioned by the great elder of the sun tribe.

Thinking of this, Zhao Fengnian asked: "elder, this should be the source of water for the survival of the sun tribe?"

"Yes, this is the biggest of several springs in the underground space, but Ah

Sun Tribe elder heard Zhao Fengnian's question and nodded, then sighed helplessly.

Hearing this, people's curiosity was hooked up by the elder.

At this time, the voice of the great elder sounded again: "after the tribe moved here, they began to transform the underground space, build reservoirs and plant crops.

At the beginning, the spring water here was not so hot, but very warm and comfortable. The crops irrigated by this spring are also growing very well.

But as time goes on, the temperature of spring water is getting higher and higher, and the holy light stone on the four walls of space is also getting darker and darker.

This has led to less and less production of crops In the end, there was no way out. The tribal leaders decided to limit the growth of personnel and made a regulation. "

This regulation is the wonderful rule touched by Mohe and lilac.

Now when people hear the elder say the reason, they all understand the rule.

"Why don't any of you look for the next place to rest? Didn't Wei Zu give you a map? " Wei Yuhan asked curiously at this time.

The elder heard not rain Han's question, the expression became more helpless.

Shaking his head and sighing, "because this is a sacred thing left by our ancestors, we have consecrated it for generations until we need it.

We found that because of the long time, the underground is too humid.

The route on the map left by Weizu has been blurred and can not be identified at all.

At that time, there was no way. Every year, the tribe sent out a number of explorers, but so far none of them has been able to successfully send back the news. "
