[The five battlefields of the past are where the five Babel Towers are located, divided into five directions, southeast, northwest, and middle, and none of them are actually in real space. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo】

Teacher Jintian's calm voice tells the truth of the world.

[That is after the cataclysm, the world plate changes, opportunities and dangers appear at the same time, and the dangerous space that appears at the same time as the strange secret realms around the world, connecting some powerful non-human foreign world spaces. 】

[Originally, because of the special closure and independence of the secret space, the aliens who invaded there did not discover the real world...]

Gu Xi listened nervously.

And then what?

[For details, use your authority to find the historical secrets of the post-catastrophe by yourself...]

Gu Xi listened to the beginning, and had the feeling of listening to legendary historical stories, who knew that the teacher would stop changing all of a sudden, let herself check it, she would like to know now!

There is no mental network here, so even if you carry a connector with you, it is useless.

Inexplicably a little stuffy.

【Teacher...】Guxi was a little aggrieved.

[Ahem, you just need to know that with the joint efforts of human powerhouses for hundreds of years, the three alien space battlefields outside the Federation have all been sealed, and they only need to be strengthened and maintained every few decades, and they will be safe and sound. 】

Hundreds of years of combat history, how can it be said clearly in a few sentences, see for yourself.

Teacher Jin Tian is very calm.

[Outside the Federation?] Gu Xi pulled his mind back and listened carefully to the teacher's lecture.

In reality, the 'Heavenly Fire' of the ice field shrank again, and the alien beasts of different sizes surrounded by it were obviously much stronger, but the 'onlookers' humans in the sky and on the ground still watched calmly.

Except for the sound of burning flames and the roar of alien beasts, humans probably only transmit and talk, and it is extremely quiet.

Gu Xi didn't care and continued to contact the teacher to listen to the class.

[There are five secret space battlefields that can connect to alien spaces, and there are two in the Federation, one in the central region and one in our southwest region, and... You'll be able to see it tomorrow morning. 】

[It turns out that the experience you mentioned is the secret battlefield you are referring to. 】

Guxi has added a little more understanding of the places to go tomorrow.

[However, why don't the two major battlefields within the Federation be sealed?] Obviously, there are three seals, but what are the last two places left for?

Gu Xi vaguely felt that maybe it was so.

[The so-called secret battlefield, also known as the 'Bloody War Secret Realm' or 'Blood War Space', is different from the secret realm you have been to, regardless of the size and environment, etc., the reason why there are two battlefields left is only half sealed, yes, it is not that there is no seal, but in the half seal...]

Teacher Jin Tian said plainly, but Gu Xi felt helpless from it.

[First, in order to take precautions, we can't let the federal soldiers lose their bloodiness and combat experience, and second, because the seals are not as simple as you think, and the other three seals are maintained by the three major forces with all their might, using endless external resources... This is one of the reasons why the Federation tolerates the recruitment of geniuses by the three major forces in the Federation. 】

【Tower of Babel?) Gu Xi asked sensitively.

[Yes, the Tower of Babel is one of the pillars of the seal, but every few decades, the resources consumed come from the outside world, and Blue Star can't muster up the material resources to maintain the seal, in fact, the seal is only delaying time, so that humans have more time to grow... You know the rules that the secret realm and reality will gradually merge!]

Gu Xi was breathing a little shorter.

Is there still so much crisis in the world beyond the bustling and peaceful cities?

[Can't you completely clean up the alien races in the secret realm?Outside of Blue Star, there should be a fourth-order powerhouse or above!] Gu Xi felt that his state of mind was unusually cold and waveless.

Using the strong to clean up tactics, in Gu Xi's view, it is a matter of course.

The life in the secret realm is dead, and the secret realm is integrated with the real world and the area of the world is not a bad thing.

【... For hundreds of years, various methods have been tried... The opposite world is different from our world rules, except in the interconnected secret space battlefield, once you mix into the alien world through some means, the heaven and earth vitality is thin or even non-existent, so that the human combat power cannot be sustained, except for relying on the strength of the flesh to fight... Heavy casualties...]

Teacher Jin Tian's tone was low.

The teacher is not talking about the 'secret realm' but the 'world'?

Gu Xi thought that when they first met, they were required to perfectly control the combat power of their physical bodies, and to survive in any strange environment, was this the teacher's prevention?

Opposite the secret realm of the battlefield, is there an 'other world'?

[The powerhouses of the third order and above could not break through the isolation of the world and go to another world before, which is a restriction of rules, but as time continues, this rule seems to be gradually weakening...]

[Just like those alien races, at the beginning, in addition to the amazing number, there were few particularly amazing existences, but now, there are more and more alien powerhouses appearing on the blood battlefield...]

Gu Xi's eyes drooped slightly, and he meditated calmly:

[It's hard for us to get over, can they easily come over and break through the secret realm to the real world?]

Teacher Jin Tian replied: [Hundreds of years ago, there were alien races similar to the limit of our first-order elite who broke through the secret realm to reality, and most of them were killed, and a small number of them merged with alien beasts, increasing the variety of alien beasts of Blue Star. 】

Gu Xi suddenly burst into a smile.

[Several secret realm battlefields have had alien races break through, the initial level is not high, only an astonishing number and with strange abilities, before being killed, human beings have died countless times... The last time they broke through, there were more and more second-order alien races, and for this reason, at the summit meeting, it was suggested that the three secret realms that were difficult for humans to defend should be sealed and suppressed by the strong...]

Gu Xi smiled, feeling a little complicated and uncomfortable.

[Is the world barrier that hinders the breakthrough of the strong corresponding?] Gu Xi gradually thought that if countless third-order alien races broke through from the secret realm space and killed wantonly, then...

[Is the alien strong, how strong?]

Gu Xi asked one after another, she knew that she was a little nervous.

Not for anything else.

Because the family lives here.

【... Xiaoxi, you are very keen, yes, the world diaphragm is corresponding, we can't go to the strong, they don't come to the strong, but the future...]

[The number of alien races is abnormal, according to research, they are multi-born creatures, some similar to the alien beasts we have here, so it depends on how quickly our strong people improve in the outside world, or whether the world barrier disappears quickly. 】

Gu Xi was silent for a moment.

[Go to the Heavenly Tower to go to the outside world, is it to become stronger, and then come back to protect the Blue Star?]

Gu Xi could tell that the teacher wanted her to know more.

[This is one of the reasons, and the other is just in case... The worst outcome can also allow the Blue Star humans to have another living environment...]

[Is it a place for the outside world to live?]

[Yes, there are countless people in the development of the place of human existence... Preparation with both hands, hundreds of years of planning...]

Gu Xi took a deep breath and asked, "Can the Tower of Babel allow all ordinary people to leave Blue Star?]

[The greatest power of the outbreak can only transfer nearly a million people at one time, this is still a theoretical calculation, and it will be destroyed at one time!] However, the starship series is being studied, supplemented by some knowledge from the outside world, once the Nine Star Array loses its blockade effect, it can take people to fly away...]

[Why does the teacher say so much to me?]

[Because of your strength, potential, and growth, and because the teacher wants you to improve yourself faster, time... Not much more...]

Gu Xi's heart was cold, [How long is it?]

[According to many researches, it is estimated that it will be five or six hundred years at most, but at least only two hundred years, so...]

Gu Xi was stunned for a moment, thinking that he had 'heard' wrong.

Replay it!

【... Five or six hundred years at most, but at least two hundred years, so...]

At least two hundred years away, you tell me...'Time is running out!'?

Teacher!

Do you know that it almost scared me so much that my Qingfeng Sword fell.
