"So... be careful."

Everyone nodded, and then, a group of them quickly moved towards the underground city...

Watch Super Son-in-Law.

Along the side of the cliff, everyone slowly descended all the way.

After about ten minutes, they finally walked down the last flight of stairs and reached the ground floor.

Su Yingxia didn't immediately go towards the city, but squatted down, gently took some soil and kneaded it in her hands to observe.

Han Sanqian is not by his side, and he is in such an unfamiliar environment, so the best choice is to try and learn what Han Sanqian would do if he were here.

She believed that Han Sanqian would do what he did now.

"Ma'am, is there a question?" Scar asked.

Su Yingxia frowned slightly: "The rammed earth is still very new, so it doesn't look like it's been built for a long time. I estimate that the construction time of this underground castle is no more than a year."

"Less than a year?" Scar was a little confused and puzzled.

This is impossible.

For the past six months, the Sky Demon Fortress has not been peaceful. Scar and the others are paying more attention to the city itself. Wouldn't they know that the construction would be completed during this period of time?

"But people can lie, physical evidence can't." Su Yingxia said firmly in a cold voice.

The fact is that the time displayed by the rammed earth is indeed within this range.

Su Yingxia also had to sigh, this is indeed very surprising, but it is an iron-like fact.

Dao Scar scratched his head and glanced at the other brothers. Seeing that the other brothers were also completely confused, he looked at Su Yingxia eagerly: "I really don't know, why don't we go into the city?"

Su Yingxia nodded: "After entering the city, you must be more careful, and your actions must be extremely concealed."

If a large number of men in black really came out from here, then it means that there must be something in this city that they need to protect.

But on the other hand, if there is such an important thing, even if the opponent is forced to need support, they will often leave some of the elite to guard it.

So, here also can not be careless.

The group of people nodded, and Su Yingxia intentionally left Scar this time outside the city for support.

There is no other reason, this guy is wearing a suit of armor, no matter how careful he is, he will always make a loud noise.

On the other hand, there is a strong point outside the city as support, which is more flexible in tactics.

For Su Yingxia's safety, Dao Scar sent his two capable men, A Zuo and A You, over there.

Although the names of the two people are too trifling, they are easy to remember.

A group of people groped in the dark and quickly entered the city.

In the city, all the houses are made of rammed earth made of yellow maps, and then shaped into an integrated structure.

Although it is simple and the structure is not too complicated, it is superior in that it is well-made, so just by looking at it, you will know that it is very strong.

The most important thing is that the main body of the house is very grand and magnificent. JrNovels.com
