People on both sides push open the stone gate together. Fortunately, the stone gate can be pushed. Although it's very heavy, it's finally pushed open with a lot of effort. But as soon as push away, it is a cold damp strong wind to face!

Mo Xiao frowned and judged, "it should be very big and ventilated."

"Big brother!" Xing Yan takes a laser torch to shine, and calls him back in surprise. Mo Xiao is also surprised to catch up.

Because his judgment is right, it's very big!

It's not just big, it's all directions! Just like the underground traffic network, there are countless branches, each of which is very wide.

"My dear, has the dark Saint group built a city underground?" Yan zhufei said in shock.

Hao Yansen didn't know how big it would be here.

And the problem is coming, so many ways, which one do they go?!

Mo Xiao picked up the map at the first time, but there was nothing on the map, only a basement.

When Hao Yansen came, he made full preparations. He asked people to take out the walkie talkie and distribute it to them. The proposal said: "we'd better separate our actions and inform each other if there is any situation. There are so many roads here, we can't find them one by one. It's a waste of time. "

"In groups of two, act separately." Mo Xiao also proposed.

"Yes." Hao Yansen nodded.

Then they immediately began to group. Naturally, Shang Shi was in the group with Hao Yansen. He could never leave Hao Yansen.

After that, Hao Yansen chose a path to explore, and so did others.

Mo Xiao and Xing Yan walk in the dark channel. Mo Xiao is not nervous at all. His eyes are sharp all the time.

This underground transportation network actually has electric circuits, but the whole island has been abandoned and the electricity can't be used naturally.

Fortunately, their laser torches can illuminate a large area.

And fumbled for a distance, Mo Xiao also probably understood what these traffic networks are used for. In fact, it's an underground city, used to contact or avoid.

Because of many roads, they can see the steps leading to the top, and there are doors on the steps. Some can be pushed open, some can not be crushed by the ruins.

Mo Xiao also judged that the underground transportation network is likely to run through the whole island.

The same conclusion was reached by Harrison.

"Young master, the dark Saint group must have spent a lot of time and effort in building this kind of place. What is the reason why they gave up this place?" Shang Shi walked behind Hao Yansen and couldn't help asking.

Hao Yansen wants to know that.

What happened, let the dark Saint group give up this place. In principle, it's hard for them to give up here.

But no matter what happened, he had a hunch that it had something to do with his parents.

"No matter what happens, find out."

"I see!"

……

But the underground transportation network is too large and has a wide range of connections. They walk and find that they don't know where they are going!

I can't find my way back.

Because there are always turnovers on the road, and it's dark here, they can't judge the way when they come.

Soon, Harrison found something wrong.

"Can't go!" He stopped and frowned.

Because they have been walking for a long time, but there is no end, and do not know where to go.

Go on, you will only get lost here.
