Fantasy: The system takes me to refine the magic formula

The weak surge of spiritual energy generated by the transmission of the two people's message did not make the devil feel it. After all, this time Longtian learned the experience and lessons from the previous time, and sent it far away from the central hall!

Now back in the hall again, Long Tian is still lost!
Under the guidance of the system, after walking around for a long time, I came to the gate of the Demon Realm!
Standing in front of the gate again, Long Tian found that the mirror from last time had become bigger!

"System! This mirror has become bigger, and the magic energy released has also increased!"

"Yes! It's a good thing you're here this time, otherwise the mainland would be really dangerous!"

"System! What do you mean by that?"

"Now the power that this mirror can carry is enough for other demons to shuttle over for a period of time! You cultivators in Tianwu Continent can't even handle one demon now, and the two will surely die!"

"This mirror actually has this function!"

"Nonsense, otherwise, how do you think the devil outside came here? Maybe he traveled through this mirror for hundreds or even thousands of years before coming here! After he came here, he slowly opened this alien passage leading to the devil world , to attract the demon energy to the Tianwu Continent!"

Although Long Tian has been talking to the system, his hands have already been placed on the mirror, and he has started to absorb the magic energy crazily!
However, what Long Tian didn't expect was that while his hands were absorbing the devil's energy, suddenly a devil's head came out from the other side of the mirror!
"Ah!!!!" Long Tian screamed in fright!
"Don't be nervous! The system is here, he can't see you!~You don't make a sound!!"

"I know! Nima scared me to death! How could a head suddenly appear!"

"He is taking a passage from the Demon Realm to the Tianwu Continent! Although this mirror is a passage from another world, the power it can hold is still too small, so he can only come here bit by bit!"

"System! Can I kill him!"

"It's not enough with your current ability, but you can absorb his energy! Use your golden nine leaves! Then break this passage! In this way, you will not lose this time! The energy of this devil , is stronger than the one outside! You have absorbed his energy, and it will probably take a long time to absorb it!"

"How do I absorb it?"

"The old way! Put your hands on his head! And suck him dry!"

"Depend on!"

Long Tian had no choice but to obey the system's instructions, and slowly put his hands on the devil's head. In an instant, the devil realized that there seemed to be someone around him. While shouting, he immediately used methods to get rid of Long Tian!

And the system sealed off the energy fluctuations in the surrounding space, and even the sound could not be transmitted. After Long Tian was reminded by the system, he started to absorb it crazily!

While the devil yelled and cursed, he felt that the devil energy in his body suddenly became less and less, and there were no people or objects in front of him, so he felt more and more frightened, but he couldn't go back now!
Looking at the energy gathered by the golden nine leaves below his dantian, and even bursting into golden light again, Long Tian was a little worried that he would break through again. You must know that he has just broken through to the Mahayana stage. If he breaks through to the middle stage of the Mahayana stage again, go back Afterwards, when he saw the leaders of the various factions, he would definitely be questioned and suspicious. This was not what Long Tian wanted, so he hurriedly turned his demonic energy into the system.

After 3 hours, Long Tian sucked the demon head dry. At this moment, there was no trace of magic energy in the demon head, only a pair of dry bones remained! !
Long Tian suddenly felt that he was a little cruel, and realized that the demons in the demon world also have flesh bodies, they are not soul bodies, they are the same as human beings, monsters and monsters, they have flesh and blood, but their hearts are black, There is no good or evil, only evil!

And the devil outside, after waiting for his partner for a long time, did not see his partner appearing, so he was inexplicably worried. Feeling the channel of the devil world, the magic energy is still gushing out like a spring, which means that his partner has not come here yet. I went to meet my partner at the entrance of the passage, and suddenly a demon general rushed in!
"Humans! They are attacking our town! My lord, do we want to fight?"

"Oh? They actually called so boldly?"

"Yes, my lord! They dispatched seven masters from the tribulation stage this time, and they also have the help of level nine monsters! It seems that the monsters in the monster forest seem to know our appearance!"

"Hehe! You stay and guard the hall! Greet Leon!"

"It's an adult!"

What the demons don't know at this moment is that Leon is already a part of Long Tian's body!
"Host! The devil and the devil are about to set off!"

"Okay! Are there any magic generals in the hall?"

"There is only one! You still have a few hours to absorb the magic energy, and then use your greatest strength to smash this glass passage! In this way, even if the demons want to leave, they can't leave! You can only Forever in the Tianwu Continent!"

"Okay!" After two good words in a row, in the main hall at the center of the Heavenly Demon Altar, a burst of super huge black magic energy slowly rose from the ground to the sky. With the head of the demon as the leader, seven generals as assistants, and a team of bone pterosaurs and various demon soldiers behind him, this huge black demonic energy began to march towards the west of the Heavenly Demon Altar!

The battle between the human race and the demon race in the Tianwu Continent is about to ignite!
