Fantasy: The system takes me to refine the magic formula

Long Tian sat at the gate of a foreign realm in the demon world, frantically absorbing a large amount of demonic energy, while silently calculating in his heart!

The last time I came here, Golden Wing flew at full speed for a day. Now Jian 23 and others led the troops of cultivators for three hours, and the Demon Gate has also started to set off. The two armies will basically meet in three or four hours. , he must break the gate of the demon world just before the two armies meet or before they meet, so that the demon leader will not want to fight. It is best to rush back immediately with a few demon generals on the spot to check the situation here. Then the masters such as Bei Nian and Jian 23 will have the opportunity to strangle a few demon generals in the tribulation period!
"Hongying! Where are you now? The devil leader and the devil general have left the central hall of the Heavenly Demon Altar! It won't be long before you meet again!"

"Master! We just broke through the city of two demonic gates! Now there is no demonic energy in it! They have been burned and purified by a large number of cultivators with flames!"

"Okay!~ Hongying, contact me as soon as you meet the devil army, or contact me before you meet! You can ask Jin Yi to go to explore the wind in advance!"

"I got it, young master! Don't worry! Young master is planning to give them a surprise just after our two armies meet?"

"Hehe! Right! Alright, Hongying, I'll wait for your news, take care of yourself!"

"Yes! Don't worry, young master!"

Long Tian closed his eyes and continued to sit at the gate of the other world in the demon world. Suddenly, the system reminded that the last left behind demon general is coming!
Long Tian followed the same pattern and quietly hid beside the mirror channel under the protection of the system!

The demon turned into a ball of demonic energy, floating outside the gate of another world, and then turned into a real entity, standing outside the gate as if waiting for something!
Seeing the other party's actions, Long Tian vaguely guessed that maybe the devil is waiting for another devil to arrive, but the devil has already been sucked dry by him!Long Tian was suddenly afraid. If he didn't come this time, he would face two demons on the battlefield in the future. At that time, none of these cultivators would be able to escape, and they would all be demonized in the end. The mainland has completely turned into a purgatory!
Long Tian quietly walked behind the demon general, then suddenly stretched out his palms, and pressed the palms of both hands directly against the left and right ears of the demon general's head. Jin Jiuye also activated at the same time, and countless absorbing vortexes opened, attaching to the demon general's head. will be on the head!
"Who! Ah!!!!!!!!!!" The demon general noticed the abnormality, and fought back while shouting, but the magic energy and magic power in his body could not be condensed at all. As long as the power condensed in one place, he would rush to The head was lost, and his own magic energy was also crazily dissipating!

In just a few minutes, Long Tiansheng sucked up all the magic energy in the body of a general who was trained as a demon in the Transcending Tribulation Stage!

"System! After this breakthrough, the speed at which I absorb energy has become faster!!"

"Yes! And didn't you notice that the Jin Jiuye below your dantian seems to have become even more strange? There were no vortexes on the original nine leaves, and only the roots of Jin Jiuye had vortices. Now even the leaves are There's a vortex! It's amazing!"

"Forget it! Now is not the time to study whether it is miraculous or not. This is the last chance to absorb magic energy!! Let's hurry up!"

Now that Longtian has dealt with the last dangerous demon general in the Heavenly Demon Altar, he completely let himself go, and put his hands directly on the mirror of the gate of the Demon Realm. All the vortexes were activated, and he began to crazily absorb the opponent's endless stream of demons. gas!
On the other side, Hongying asked Jinyi to check the location of the demon leader's soldiers quietly, and at the same time told Bei Nian, Ji Yurou and others about Long Tian's thoughts. They looked at each other and felt that this method was feasible, so they and Jian 23, Xue Tiankuang and others discussed the countermeasures!
"Hongying! A huge cloud of demons floated in the distance! One of the masters who was beyond the transition period felt my presence, and I came back! I think it must be the group of demon generals and demon leaders that the young master mentioned It's gone!" Gold Wing reported to Hongyinghui after landing!
Jin Yi spoke very loudly, and Jian 23 and the others naturally heard: "Everyone fly to meet them!"

All the cultivators, no matter from the Nascent Soul Stage to the Fusion Stage, from the Transformation Stage to the Mahayana Stage, all flew up, forming a huge camp of cultivators, facing the magic cloud far away!

Hongying hurriedly contacted Long Tian at this moment: "Master! We met!"

"Okay! I got it! I'll act immediately!"~After receiving Hongying's news, Long Tian didn't dare to delay for a moment. Be demonized!

At this moment, the demon leader Ryan led all his subordinates to the other side of the large army of practitioners!
"Hahahaha, as expected, there are ninth-level monsters joining your human camp! But don't think that you can repel our demons by doing this! Our demons will definitely take this small planet into their pockets, and then demonize us. subordinate planet!"

The coercion of the devil made everyone very uncomfortable. The monks in the transcending tribulation period felt the pressure, and the monks in the Mahayana and fusion period behind them were even more miserable!

"The devil! I advise you, go back where you came from! Otherwise, you will die without a place to bury you today!" Jian 23 took out the immortal weapon of the town - the Qingjue sword!
And Bei Nian also took out the Tianwu Academy's immortal weapon, the Saint Yuan Mirror, to use it against the pressure of the devil, so that the disciples behind him could feel more comfortable!
"Hahahaha! A little cultivator still likes to talk big! Then I will see today, how you let me die without a place to die!"
