The universe is vast, and the Milky Way alone has countless star fields, and the solar system is only an insignificant part of it.

However, the earth in the solar system once had a top civilization, and technology and martial arts have reached the pinnacle.

At that time, there were countless powerhouses on the earth, and there were no less than 100 masters of the level of the four great emperors of the galaxy alone.

Later, the earth suffered a change, and the strong fell one after another, and only a few lucky ones survived and left their own lineage.

After the disaster, the earth's technology fell to the bottom, and the survivors could only practice martial arts, but each person had different qualifications and learned different things, and then gradually evolved into three mainstream schools.

Martial arts, Shinto and demons.

The road of martial arts, the martial artist practices qi and cultivates the truth, the heaven and the earth, the people's hearts, the ultimate realm, the world and the world can travel, the universe has no limit, and the martial arts enter the Tao.

Shinto focuses on bloodline, focusing on developing the potential of bloodline, and can obtain huge power in a short period of time, but unfortunately the stamina is weak, and few people can reach the ultimate realm, and the gods and mutants take Shinto.

The Demon Road is the Yuan God, with the gods to control the sky, to explore the origin of the universe, but unfortunately the entry is the most difficult, and it is easy to deviate, so it is not only the way of magic, but also the way of evil demons, the ancient one is the way of God, although the power is not strong, but it is weird and inexplicable.

Although the starting point of the three paths is different, after cultivating to the advanced realm, different paths lead to the same end, and the Northern Underworld Thunder is the best example!

Bei Ying Lei first cultivated martial arts, comprehended the realm of divine skills, and then broke through the divine body with the help of blood, broke through the realm of the second level of the divine domain, and then went up to break through the heart level, fused the three treasures of essence and energy, and practiced the cosmic force.

The four great emperors of the galaxy are all overlords who comprehend the force of the universe, and they can suppress a star field by themselves.

The ancient one told the Northern Thunder that there was another realm above the cosmic force, that is, the "Immortal Dao".

Immortal Dao, as the name suggests, this realm has transcended the scope of human beings, become immortals, and evolve the origin of human beings to another level.

For thousands of years, there have been countless strong people in the three levels of the Divine Domain, and there is no shortage of strong people who have comprehended the force of the universe in each generation, but there is only one "God Killer" who has achieved immortal Taoism.

If you want to help Xiao Yue'er remove the poison of the sleeping curse, you must achieve the "Immortal Dao Realm".

"Master Gu, how can you achieve the Immortal Dao realm!" Bei Ying Lei couldn't wait to ask.

Gu Yi drank a cup of tea slowly, shook his head and said: "I don't know how to achieve the Immortal Dao, throughout the ages, only the god-killers more than a thousand years ago can achieve the Immortal Dao, as strong as the four emperors of the Galaxy, not trapped outside the Immortal Dao for thousands of years!"

Bei Ying Lei was gloomy when he heard this, the immortal path was ethereal, and he didn't even have a broken "heart pass" now, let alone the immortal road above.

Athena also persuaded: "You better wait patiently for me to train Xiao Yue'er's body to the god-level realm!"

Gu Yi also agreed: "With this girl Divine Race Yuan Shen feeding back the vitality, you can achieve a divine body in ten years at most, and you don't have to risk achieving the Immortal Dao!"

Hearing Gu Yi's words, Bei Ying Lei's eyes lit up.

"Master Gu, but there is a way to achieve the Immortal Dao?"

Gu Yi smiled bitterly: "I really didn't lie to you, Immortal Dao Miao, I don't know how to achieve it, but there is a way, but there is hope for a breakthrough!"

Bei Ying Lei humbly asked for advice: "Please also ask the master to give advice!"

"The method is too dangerous, and I don't have 100% confidence in breaking through the Immortal Dao, so don't say it!" The Ancient One has always refused to reveal.

Bei Ying Lei was in a hurry, so he wanted to force Gu Yi to say it, but it was Athena who was a bystander, and he grabbed Bei Ying Lei and said.

"Master, could it be that your solution is the Time Stone?"

Bei Ying Lei was reminded by Athena, and then he reacted, and guessed in combination with what the ancient one said before and after.

"Could it be that you are using the Time Stone to return to the time of the God Slayer and ask him for advice?"

"Alas!" Gu Yi lamented: "The girl is really smart!"

"Throughout the ages, only one god killer has achieved the Immortal Dao, so naturally asking him for advice is the fastest way to do it, but this method is too dangerous!"

"I said that time is one of the iron rules of the universe, and the physical body will be counterattacked when it travels through the past and the future, and only a god-level primordial god is possible!"

"However, there are still hidden dangers in this method, even if you go back to the past, the primordial god will have to be possessed, but it is difficult for the human body to accommodate the god-level primordial god, and those who have a divine body are strong and will not be easily possessed!"

"The most important thing is that even if you are lucky enough to meet a suitable host, it does not mean that the God Slayer will tell you the mystery of the Immortal Dao!"

With what Gu Yi said, Bei Minglei's face turned pale, and he also found that it was fundamentally difficult to go back to the past, and it was possible that the gains outweighed the losses.

"Young man, you better wait patiently for this girl to achieve a divine body, but ten years have passed in the blink of an eye!"

Bei Ying Lei did not listen to the advice of the ancient one, but thought about it seriously.

According to what the ancient one said, the primordial god traveled through the past, how similar it was to his previous reincarnation and rebirth, it may be difficult for ordinary people, but for the reincarnated experienced Northern Underworld, the danger is not as great as imagined.

And the real difficulty is nothing more than how to get the Godslayer to teach him the secrets of the Immortal Dao.

The god killer is not the father of the Northern Thunder, why did he help him become enlightened for no reason, and from the perspective of the style of the god killer, his temper is not very good, and it is possible to cut the Northern Thunder without saying a word.

Another danger that Gu Yi didn't say, that is, how did the Northern Stygian Thunder believe the words of the Ancient One, in case he took the opportunity of the Yuan Shen to leave the body and kill the Northern Immortal Thunder's body, even if he got the secret of the Immortal Dao, it was not a void.

After thinking about it again, Bei Ying Lei still firmly said to Gu Yi: "I'm willing to take a risk!"

In fact, the adventure of the Northern Immortal Thunder was not only for Xiao Yue'er, but also for himself, and the power of the Supreme Immortal Dao made him can't help but want to explore.

The battle with Darkseid made the Northern Thunder feel powerless, he hated it, he wanted to get stronger, and the only way to make him stronger was with the Godslayer.

Moreover, since he achieved the god-level realm, the Northern Immortal Thunder has a mysterious sense of danger, and this time he did not feel the aura of danger.

The firmness of the Northern Thunder infected the Ancient One, and his eyes showed a look of struggle, and his heart began to waver.

"It's okay if you want me to help you, but after you get the secret of the Immortal Dao, you must share it with me!"

Bei Ying Lei suddenly, it turned out that the person who wanted the secret of the immortal path the most was Gu Yi, but it was a pity that he specialized in magic, and his physical body was extremely fragile, once the original god left the body, the physical body would inevitably decay, so he didn't travel through time by himself.

And what makes Gu Yi even more helpless is that his limit is approaching, and he doesn't have much life, if he doesn't break through the realm again, he is not far from death.

"Okay, as long as I can get the secret of the Immortal Dao, I will share it with the master!"

Gu Yi looked carefully at Bei Ying Lei's eyes, as if he wanted to see the depths of his heart, and looked at it for ten seconds.

"I believe in you!" Gu Yi refined the power of the primordial gods, and he could sense that the Northern Thunder was not lying, at least at this moment, he was not lying.

After the ancient one promised the Northern Thunder, he took him and Athena into his most secret place, the secret room where the time gem was kept.

The Chamber of Secrets is magically protected and difficult for anyone who does not know the inside story to discover, and in the middle of the Chamber there is a small pillar on which the Time Stone rests.
