Fantasy: The system takes me to refine the magic formula

Yanhuo remembered that after the Great Tribulation in the Immortal Realm, he had just entered the Immortal Emperor Realm, and suddenly one day, while he was cultivating, an extremely powerful energy instantly controlled him in place!
"Is it the Immortal Emperor Yanhuo!"

"It's me! Which senior is it!" Yanhuo asked nervously!He is very scared at the moment!You must know that now that he is already an immortal emperor, someone can suddenly come to his immortal mansion without a sound and imprison him instantly. This is not something an immortal emperor can do, even if it is a top-level The peak of the Immortal Emperor realm is also impossible!

After all, Yanhuo has also seen the top peak Immortal Emperor!
"Flame! After this immortal calamity, the entire fairy world will enter reincarnation. From then on, the realm of the immortal emperor will be very difficult to break. Only the chosen one of the savior will lead you to break through the realm! Enter the realm of God! Would you like to Waiting for this person to appear in my secret treasure!?"

"Dare to ask who is the senior?"

"You don't need to pay attention to who I am, and now you don't know my status with your realm! I just ask you if you are willing or not!?"

"Senior! How long do I have to wait?"

"Maybe 10 years! Maybe hundreds of millions of years! But in my secret treasure, you can continue to practice and have two chances to break through! I will help you!"

"This..." Yanhuo hesitated, but he thought that when he cultivated, it would take a long time!It takes millions of years or more to break through level one!
And the opponent's strength and realm are obviously not at the level of the fairy world, Yanhuo thinks, maybe this is also a hope!
"Senior! Junior promise!"

"Very good! Your choice will help you escape some disasters! Come with me next!"

The moment the man's voice fell, Yanhuo suddenly felt that the scene around him had changed, and he appeared in a wonderful space!

"In the future, if someone breaks into your challenge tower to fight, whoever can defeat you, follow him out! He must be the chosen one! He will lead you into the God Realm!"

"It's senior!"

In this way, Yanhuo waited for a million years, and during these million years, a few people broke into Yanhuo's territory, and then they all failed, and finally disappeared in the long road of cultivation !
Now there unexpectedly appeared a young boy in the realm of the Immortal King, who easily defeated him with an energy three realms lower than his own, which made him feel unbelievable, and at the same time, he believed that the boy in front of him was the former Tianxuan man!

And during these millions of years, Yanhuo has been cultivating in this realm, and at the same time, that person has found Yanhuo twice, and helped him break through to the peak of the Immortal Emperor realm!
It's just that no matter which time, Yanhuo never saw the appearance of his true self!This made Yanhuo finally confirm that the opponent is definitely the super god who controls the six realms!
At this moment, Yanhuo looked at Longtian's back and admired it very much, because after Yanhuo was defeated, Longtian disappeared from his vision, and eight months later, Longtian was already a master of the immortal level. Even though Yanhuo has practiced for millions of years, he has never seen a person who can cultivate from Immortal King to Immortal Venerable in just a few months!
This made Yanhuo [-]% certain that Long Tian must be the person from the Profound Sky that the voice said could lead him to the God Realm!
And observing the current situation in the fairy world, there is only one fairy emperor, which makes Yanhuo seem to have noticed something!
At this moment, Longtian is looking at the books collected by Yanhuo, one of which is the Complete Alchemy in the Immortal World, which contains all the elixir, and Yanhuo's incomparably large amount of materials also provides Longtian with sufficient experimental items!
The other book is the Great Art of Artifact Refining in the Immortal World. Long Tian flipped through it casually, and found that the method of refining the weapon was very familiar and seemed to be very similar to what he had learned in the lower realm, so Long Tian just flipped through it casually, and put it away. Mastered this great art of refining!
Luoxi and Hongying were reading different books, when suddenly a powerful aura descended, Longtian and Yanhuo felt each other's arrival at the same time, glanced at each other, Yanhuo said: "Young master, follow along Shall I go to meet the guests together?"

"Let's go! I also want to meet the only immortal emperor in the legendary fairy world! Hehe, I just ascended, and I am so lucky to have the opportunity to meet the only immortal emperor in the fairy world!" Long Tian finished speaking Finally, let Zhang Mian and the other three wait in place, and fly away with Yanhuo!
"The young master said he was going to see the Immortal Emperor? Isn't Yanhuo the Immortal Emperor?"

"It's probably Yanhuo's return, another Immortal Emperor sensed it and came here!! The coercion just now was too terrifying, I felt like I was going to dissipate in an instant!" Luo Xi patted her chest and said nervously!
"Sooner or later, I will definitely cultivate like this! I won't give up easily!" Hongying was very touched!
"Sister Hongying! What exactly is your inheritance? It feels so powerful! You were cultivating when we were in the lower realm, but now you are already in the realm of the fairy king, and you can continue to practice. Is it possible that your inheritance is also immortal?" Is it inherited by the emperor?"
