Fantasy: The system takes me to refine the magic formula

After cleaning up the scene, Long Tian quickly left, then came to the dense forest, and quietly entered the system battle space!
"System! I got it done! What are you looking for from me?"

"Host! Three things. First, you must not be seen by other immortals when you use Jin Jiuye in the future. This trick is too similar to the blood demon method of the demon world. You will be regarded as a creature of the demon world and be attacked by the fairy world." Everyone's hunted down!"

"Okay, I know, I've always known!"

"Second! It's the bright spot you found later! It's getting bigger! It seems to be expanding, and a strange energy explosion is being produced inside it! What's even more strange is that this spot of light seems to have a wonderful relationship with the golden nine leaves of your body. The link! When you were breaking through before, this light spot actually provided you with infinite power!"

"It's amazing to have a link with my Jin Jiuye!"

"Yes! Third! It's about the system!"

"Well! Tell me! It's rare that you are so serious! I'm all ears!"

"Host! Now the system's refining space has also been opened! And the battle space can actually be opened!"

"? What do you mean? Isn't the combat training space always open?"

"Host! The system means that the space of the battle tower can be opened! All the people fighting in it can be released to follow you in the fairy world!"

"...Really! If this is the case, can it be used against god-level characters in the battle tower?"

"That's not allowed! Don't worry! Wait for me to finish speaking! The premise is that you must win the challenge before you can take people out! But I can help you cheat!"

"How to say?"

"For example, if you are going to challenge the fairy level now, you must not be able to beat it, but the system can help you bless the immortal energy, so that your immortal energy will be endless, and sooner or later this immortal monarch will be exhausted, and you will be able to take it out when you win !"

"Then I will challenge the Immortal Emperor now, can you help me!"

"Yes, you can't beat it!"

"I can use Jin Jiuye, then absorb the opponent's immortal energy until the opponent is exhausted, and then defeat him!"

After Long Tian finished speaking, the system became quiet!

"Host, you are such a vicious guy! Go and try it!"

"! Damn! I just said it casually! Is it really possible?" Long Tian knew very well what the status of the Immortal Emperor was in the Immortal World!I also know that if an immortal emperor protects me, then I can really travel the 36 stars of the fairy world without any worries!

"Try it! I will help you stabilize Jin Jiuye!"

"No, system, why are you so anxious about my breakthrough or something?"

"There is a mission for the system to come to you! And this mission is also time-sensitive! If it expires, the system will be punished!"

"...What punishment did you receive?"

"Maybe it's a downgrade, maybe it's something else!"

"Hehe, isn't that great!"

"Okay? Once I'm downgraded, you won't be able to open any space!"

"System! Immediately help me enter the system training 1-on-1, I want to challenge the Immortal Emperor!"

The moment Long Tian finished speaking, his eyes went dark, and then he appeared on a vast lake wave!

"! Strange! The one who came to challenge this time is actually only for the Immortal King! And the immortal energy around him is very messy!"

The man opposite Longtian looked at Longtian and said calmly!
"Are you the Immortal Emperor?"

"That's right! I am Immortal Emperor Yanhuo! I have guarded the battle tower for millions of years! Why do you, a little fairy king, challenge me! Don't you know that you will lose if you cross three levels?"

"Arrogance and talking too much! ~ Jin Jiuye, let me go!" Long Tian said that he would hit as soon as he said, and he didn't hold back at all, but Long Tian's movements, including the control of immortal energy, were not enough for Immortal Emperor Yanhuo. Equivalent to the state of nothing!
Although Jin Jiuye wrapped Immortal Emperor Yanhuo's body, Immortal Emperor Yanhuo was surrounded by an energy shield!
"Little guy, this thing is very interesting!"

"The more interesting ones are in the back! Suck it for me!" Long Tian said fiercely, and with the help of the system, he instantly stepped up his efforts to absorb one-third of the energy of Immortal Emperor Yanhuo's fairy shield!
"What! How is this possible!" Immortal Emperor Yanhuo was surprised!
Then Immortal Emperor Yanhuo casually slashed at Dragon Angel with a flame slash, Long Tian didn't resist, he can play with fire as well as Long Tian!
The flame of Immortal Emperor Yanhuo is the Heavenly Sun Sacred Fire, its rank is lower than Liuwei Tianhuo, so it just drifted away from Longtian's body!
And when Immortal Emperor Yanhuo used the immortal energy to attack again, he found that he could not condense the immortal energy, which made Immortal Emperor Yanhuo serious!
It's a pity that it's too late!
After all, Longtian has the help of the system, and it is in the system space!If only relying on Longtian himself, he would not be the opponent of Immortal Emperor Yanhuo at all!

Now the host of the system wants all of Yanhuo's immortal energy to be given to Longtian. Seeing that Longtian's body is getting bigger and bigger, and the immortal energy in Yanhuo's body is becoming more and more depressed!
"Host! Stop! Otherwise, Yanhuo will regress!" The system yelled!
After hearing this, Long Tian hurriedly stopped, and then crazily adjusted the immortal energy in his body with the help of the system, otherwise Long Tian would definitely explode and die in the next moment!
"I! I lost to a fairy king..."
