"Babel? It's a place I miss a little...... Seeking the Heart, you and I built it together, and poured a lot of effort into sealing the main spatial passage from the Demon Realm to the Human Realm. As long as the main spatial passage connecting the human world and the demon world has not been unsealed, then even if someone in the human world and the demon world tries to circumvent our seal and try to open the space door, it will never be possible to open a stable large spatial passage for a long time so that the demon world has a chance to invade the human world......"

An ancient building buried deep underground, built nearly 2,000 years ago by Xunxin and Sparta, to prevent the lives of the demon world or the human world from trying to open the spatial passage for their own benefit. The precautionary measures of heart-seeking and Sparta were not necessary in the eyes of mankind at that time. In the era when demons are raging in the human world, as long as human beings who have seen the horror of demons will never want to open the door that can bring destruction. However, only a hundred years later, many newly born human beings have become extremely interested in the horror that has great power in the record, even if the entire human world is gathered, and it is even irrepressible in the power of controlling demons.

"Although the Tower of Babel has continuously extracted power to strengthen the seal of the spatial passage, it cannot stop the human desire for the unknown. Well...... This is also the nature of all life, an unstoppable instinct. This ability to move forward into the future is the embodiment of the infinite of all life...... It's just that human beings do go in the wrong direction sometimes, and this time, Virgil made a decision that can be said to be wrong. ”

Ordinary humans, standing at the foot of the tower, are probably simply amazed by the fact that this giant structure has almost never been recorded in history. However, the mind-seeking can feel it. Throughout the Tower of Babel, a familiar aura was moving in it. Especially the Enma Knife made by Xun Xin himself. The continuous spatial fluctuations generated by the unforgeable laws of space made the heart seeker immediately discover the whereabouts of its holder.

After the Tower of Babel was manufactured. Due to an urgent mission, Seeker was forced to go to Panspace 65535 of the Infinite Heart to say goodbye to Sparta. For thousands of years, only Sparta guarded the human world, which was a heavy burden for Sparta. Humans, demons, and angels all want to take advantage of their own inadequacy to reopen the sealed space channel between the human world and the demon world. Humans believe that they have the support of technology and the heavenly realm, and they can already fight the demons that dye the earth red in the records, and even invade the demon realm, opening up a new world for the increasing population of humanity. And the environment and competition in the Demon Realm are really not suitable for the survival of low-strength level lifeforms. In the constant killing and devouring. Every day, tens of thousands of demons die in the cannibalism of their own clans, so the land of the demon world is dyed black and red by the blood of demons day after day, as if the color of death can never fade. Living in such a harsh environment, the demons naturally want to invade the human world, which is said to be almost equivalent to the ecological competition for the demons, and there is no ubiquitous smell of sulfur, but the smell of fragrant food. And the inhabitants of the Celestial Realm, who were originally formed by humans in order to get rid of the suffering of the world and the threat of demons, condensed by the faith of countless people, took the Demon Realm as their main goal. All the time they count on invading the Demon Realm and fulfilling the mission given to them by their creators, humans.

Under the effect of the Spiritual Thin Prison, it is difficult for the beings of the Demon Realm and the Heavenly Realm to directly interfere with the Human Realm. But it was the only remaining human beings that made Sparta feel very helpless. Sparta watched as humans acted ignorant and arrogant. But it can't directly stop human beings from digging their own graves. When he left, he handed over the peace and future of the human world to Sparta, hoping that Sparta could protect the stability of the human world instead of him. If Sparta really by violent means. Forcibly blocking humanity's research into space passages is a vow made by himself when he left. Contrary to words. Human beings don't need to manage themselves all the time. God-like characters. At that time, Xun Xin did not understand the consequences of life-limiting actions. But the choice made by the will to seek one's own mind and the idea of empathy is still not to want humanity to be conditioned by a life above itself, even if it may prevent humanity from causing a crisis that destroys itself.

"If the catastrophe caused by the actions of mankind is still within their bearings, I hope that Sparta you will not intervene. This is a decision made by humanity itself, and the consequences should be borne by humanity itself. I think that our positioning should be the last line of defense of life, to replace them against an irresistible catastrophe, and that is enough. When they choose the wrong direction, how can they understand that their actions are wrong and stupid if they don't suffer some hardships. I will probably blame us for hindering the development of mankind, and most seriously, it will even make mankind lose the motivation to move forward and become a machine that only knows how to obey orders......"

Following the advice of the heart-seeking, Sparta did not intervene in the actions of humans, angels, and demons trying to open the spatial passage. However, before the search for the heart could return, Sparta also promised to ensure that the human world was in a state of peace. If the gates of hell reappear, the human world will probably be plunged into war again. Without the help of seeking the heart, and adding the not weak angelic side, even Sparta did not dare to guarantee that he could fully control the scope of the war in the human world and not spread too much. With the current ability of Sparta, what can be guaranteed to be done, that is, to make the seal of Babel on the Demon Realm stronger and stronger, and to prevent smuggling between the Human Realm and the Demon Realm as much as possible. In this regard, Xunxin gave Sparta a depressed evaluation.

"It's similar to the work of the border guards in the source world, but the burden and area of the work are much larger......

In addition to the more complex structure inside the Tower of Babel, Sparta also placed more restrictions on the seals that were eventually used to open the spatial passages. The initial restriction set by Mind Seeking and Sparta was to use their own bloodline and human bloodline at the same time to achieve the lifting of the seal. But after Xun Xin left, Sparta gradually felt that since humans themselves wanted to break the seal, it was too unsafe to let ordinary human blood as a seal. At this time, Sparta discovered that there are special humans among human beings, that is, the light race and the dark race. Not only are they scarce in number, but each of them has quite strong strength, so they will not be forcibly caught by ordinary people as a sacrifice for unsealing, and as a condition for unsealing the seal, it is very suitable.

"But, Sparta, after that battle of Demon Consciousness, I'm afraid the seal of Babel Tower has been damaged to the point that it is almost impossible to repair, right?"

"yes...... If you seal it again, you will have a scene that cannot be concealed. For the entire human world, our move to reseal the seal will have too great an impact on their development, and will bring the scientific and technological progress of mankind to a standstill, and move towards the path of studying demons and the heavenly realm. It's not yet time for humans to wield demonic powers, so let's do it, Seeker. ”

Standing beside the Soul Seeker, Sparta looked up at a position in the Tower of Babel, and his eyes seemed to pass through the thick magical walls to see Virgil walking around and studying in it. As Virgil's father, Sparta didn't know what to say now. The seal he set up was about to be unlocked by his own children, and it was really a trick, and even another seal set by Sparta had no effect on it.

"In order to prevent the seal of the Tower of Babel from collapsing, I left the sword in the Demon Realm to strengthen the seal. Only if the sword and my companion sword have the same demonic power as me, the two gems I gave to Eva will have the possibility of breaking the seal again. Without these two gems or my bloodline, it would be impossible to break the seal with the sword I left in the Demon Realm. I didn't expect it......"

When Eva thought she was going to die, she gave Sparta to her two children as a token of marriage. Unexpectedly, at this time, Virgil wanted to use the hope of his parents to open the door to the demon world.

"However, if you only have one gem, it is not enough to open the passage. The settings I added to the seal require two gems to break through the seal. In the human world, there is no place for this gem, and Virgil does not have the ability to fully fill the demonic power of the gem in a short period of time. Unless ......"

Halfway through that, Sparta suddenly thought of the possibility that he would not want to continue thinking about it. And this possibility, Xun Xin also thought of this possibility immediately after Sparta stopped talking.

"If you really go somewhere, Sparta, what will you choose to do?"

“…… Sorry, I haven't figured it out yet. Please give me some more time......"

It is precisely because of the human world that if you want to get the key that can open the demon world, I am afraid there is only one choice. Thinking of the scene of fratricidal brothers, Sparta, as a father, really didn't know what to do. And as Xunxin, who watched the two children grow up, he was emotionally reluctant to attack the two children. The father and the godfather, two people with the same sentimentality, left the Tower of Babel without being noticed by anyone......

'Just now, it seems that someone familiar is watching me......

Virgil looked up, but in the empty library, only large clouds of dust fell, and the boundless silence was left for the lonely Virgil. After a few self-deprecating laughs, Virgil continued to devote himself to the books stored in the Tower of Babel, searching for valuable materials stored there.

"It should be an illusion, it'......" (to be continued, please search, the novel is better and faster!)
