After reaching such a conclusion, Han Chen only felt a chill coming from his back neck.

When he changed his mind in this direction, he suddenly found that such military facilities were not only available to the eternal God, but also existed in the starlight Federation.

In fact, it is not easy to deal with the enemy as long as there are some powerful military facilities.

"Now according to their response measures, we can infer that there should also be some threats under the earth's surface. Such threats actually do great damage to them, so they don't pay attention to them. Only in order to prevent the underground things from damaging, they will take some precautions."

"If you want to prevent the underground things from coming out and damaging, then landfill should be a very appropriate means."

"Nine out of 10 things underground are not human beings. Otherwise, we should at least obtain the divine domain wrist watch, so as not to enter the blind area of our exploration."

For the zulongxing people who wear the divine domain wristwatch, the earth has killed almost once in the past wars, but their number is too large, so the killing speed of the earth can not catch up with the resurrection speed of the other side.

In such an environment, if there are still some people who are qualified to wear a divine watch, they can not be detected by the earth.

So what they're guarding against should not be human beings.

Or it shouldn't be a conceptual human being.

Moreover, such military facilities have been gradually abandoned. They may have given up their underground defense, or because they feel that the underground is no longer a threat to them.

After all, with the power of the divine realm, zulongxing should also have some means to drill the earth. It should not be a problem to explore the old opponent.

Thinking of this, Han Chen immediately sent a message to find alijie and get some information from her.

"Alijie, in the past wars of zulongxing, whether there were underground enemies, their records, or in peacetime defense, whether there were underground threats? Here are some coordinates. Go and find out about the garrison here. "

After the message was sent out, Han Chen quickly got a reply from alijie.

There may be some threats under the surface of ZuLong! However, it is not recorded in history. The coordinates you provided for the garrison there have also been explored. They have never received any order to guard against the enemy. They just want them to stand by there without any instructions. 】

after receiving the reply from alijie, Han Chen fell into deep thought.

The defenders there didn't receive orders to defend and guard? This is the biggest abnormality! Even in the mainland, we should at least guard against some rebel forces!

Being unprepared for nothing is the biggest problem.

"Since there are military fortresses there, they must be guarding against some enemies. However, the garrison stationed there has not received any orders, and there is no record in history that any enemy came from the underground. Of course, zulongxing's conscientious historians have died, and it is normal that they have not recorded or revised the history."

"But why didn't they get any orders?"

Han Chen some doubt, "do you want me to go underground to explore it?"

Unable to understand, Han Chen decided to take a look in person.

In any case, even if there is any danger, the loss is only an incarnation. The Avatar was originally used for death, and there is nothing to be regretted.

On his way to such a military fortress, he suddenly received a message from Li long.

[when the wild geese fly to the south, when the geese rest at night, there will be a wild goose on guard. Some crafty hunters will constantly expose some traces, so that the wild geese on guard can remind their companions, but after the companions are awakened, the hunters will hide.

After several repetitions, the wild geese, who no longer believe in their companions, will begin to beat up their companions, and finally be won by hunters. This kind of thing also happens on the battlefield, causing similar troubles to some invaders. Therefore, a certain country has invented such a warning method, that is, let the sentry guard, but does not rely on the guard of the sentinel. 】

"not relying on sentinel vigilance? Do you rely on instruments? "

Han Chen continued to look with doubt.

[they asked the sentry to stand in a conspicuous place, where they could be observed in the rear. If the sentry left, they would be punished directly. But if the sentry was just lazy or sleeping, they would ignore it. However, if the sentry was killed, it would indicate that the enemy had invaded, and all the people would pour out. At this time, the baking cake was no longer used For the people on guard, but as a decoy. 】

after seeing this, Han Chen's pupil shrank.

He asked himself that he was also a decisive man, but this kind of thing was really unexpected to him.

It's not that his IQ is not enough, but that he thinks from different angles.

When the Sentinels are killed, this is the precursor of the enemy's invasion. Such vigilance thinking is simply inhumane and uses human life as a tool.Although on the issue of position, we should not use the simple right and wrong and whether there is human nature to distinguish, but this also caused great trouble for Han Chen's substitution thinking.

It is also because Li Long is a member of the military that he can think of this possibility.

[the reason why they did this should be for the sake of confidentiality. They wanted to bury all the people who knew the secrets under the surface. If they told the legions guarding there that they needed to guard the underground things, it would be equivalent to telling others that there was something underground.

But if they use their lives as bait, when things under the surface really come out, they will detect whether those people's lives have disappeared, and then use some unknown means, or let those who have the right to know the secret to do it, and bury everything. 】

"Hoo ~"

Han Chen took a deep breath and felt a little depressed.

In fact, this should be a good news for him. After all, compared with the past, at least now he has found a reasonable entry point.

It's just that he still feels a little depressed.

The secret of ZuLong star is in front of us. What are you worried about? We're going to find out.

Or at least there's a clue.

With a definite clue, even if it is to send the incarnation again, the wise man of the month must not refuse.

"Anyway, I have to go down and have a look."

In this way, Han Chen is ready to find a place to go deep underground.

"Entrance, entrance, no, if there is an entrance, then there are so many things suitable for landfill. They should not worry about anything!"

Thinking of this, Han Chen's night devil incarnated into a shadow, and then hid in the void, deep underground.
