Ye Feng suddenly jumped out of the darkness, leaving all the demons present stunned.
Even the leader of the demon clan was stunned for a moment.
Because Ye Feng was currently wrapped in a black robe, and his whole body was full of pure demonic energy, making the group of demons think that he was their companion for a moment.
But the next moment, the terrifying and cold murderous intent came out of Ye Feng's body, causing the expressions of all the demons present to change drastically.
But just this moment of confusion gave Ye Feng enough time.
Back when he was on the battlefield outside the territory, Ye Feng was able to kill a demon leader when he was in the ninth level of the magical power realm.
Now Ye Feng has entered a life-threatening situation, and his combat power is many times stronger than before on the battlefield outside the territory.
So at this moment, Ye Feng caught the demon commander in a daze for a moment, and slapped him to pieces with a big glazed crystal hand in front of the demon commander's horrified eyes.
"Crack!"
Ye Feng instantly reached out and grabbed the transparent glass tube that contained the energy of the entire mineral vein.
"nice one!"
Almost the moment he caught it in his hand, Ye Feng felt a majestic mountain-like energy stored in that small glass tube.
"Boom!"
Suddenly at this moment, there was a loud noise outside.
Swish, swish, swish!
It was Narcissus Lan, Shi Kongfan and others who heard the sound of fighting in the mine and rushed in.
Buzz!
Ye Feng's eyes flashed, and he immediately and calmly put the transparent glass tube in his hand that stored the energy of the entire mineral vein into the storage ring.
Then Ye Feng stepped forward, looked at Narcissus Lan and the others, and said with a smile: "I didn't expect you brothers and sisters to move so fast."
"It's the human race!"
At this time, more than a dozen demons in the mine immediately roared and started killing around them.
"A group of low-level demons dare to act arrogantly in front of me!"
Shi Kongfan was very powerful, and the sword intent of the Dacheng Sword Emperor exploded instantly.
Clang!
He held the ice crystal sword in his hand and shouted coldly: "Instant flash kill!"
Swish! Swish! Swish!
Almost at the next moment, Shi Kongfan's entire body turned into a series of phantoms, passing through more than a dozen demons in an instant.
"boom!"
"boom!"
"boom!"
The dozens of demons didn't even react, and their bodies exploded in an instant.
"What a powerful sword."
Ye Feng's eyes lit up slightly. Although this Shi Kongfan was a master in the eight-time death-killing realm, he was definitely much more powerful than Narcissus Lan, who was in the ninth-time death-taking realm.
After all, sword cultivation is originally the most cutting-edge and most lethal among many ways of cultivation.
"The great... demon is about to come... you... you stupid humans... are all going to die..."
At this time, a demon in the distance who was not completely dead showed a ferocious smile, then spat out a mouthful of black blood, tilted his head and died.
“It’s amazing.”
At this time, Huang Wu, Liu Piaopiao, and Shui Bingyan looked at the huge mine pit. The pit was already empty, and the three people's eyes showed wonder.
Narcissus Lan also had a hint of amazement in her eyes at this time and said: "I really don't know how these demons did it."
Ye Feng stood aside and said nothing, his eyes calm.
"We can't go any further into this underground world. The underground changes this time are simply not something that low-level students like us can detect."
Narcissus Lan made a quick decision and said: "Our mission has been completed. Now we need to return to the academy immediately and report this matter to the higher-ups."
"I agree."
Huang Wu nodded and said: "Our best choice now is to return to the academy and let the academy send real strong people to deal with this matter."
Liu Piaopiao felt a little timid at this time, and she nodded.
Shui Bingyan naturally obeyed the arrangements of her clan sister.
Shi Kongfan spoke up at this time: "I won't go back for the time being. I need to continue to practice in this underground world, hunt down demons, and hone my swordsmanship."
After saying that, Shi Kongfan stepped out directly and disappeared at the end of the deserted land in the distance.
Ye Feng also spoke out at this time: "Brothers and sisters, please go back first. Like Senior Brother Shi, I want to continue to practice in this underground world for a while."
Shui Bingyan did not stop Ye Feng's decision, she just said with worry in her beautiful eyes: "Ye Feng, the underground world is changing now, you must be careful."
Ye Feng smiled slightly and said: "Don't worry, I have the means to disguise myself as a demon. If I encounter any crisis, even if I can't defeat it, I still have no problem escaping."
After the words fell, Shui Bingyan and others nodded and left in a hurry.
This time the movement of the demons was so great that they couldn't wait to return to the academy to report the matter.
Perhaps only powerful elite students or noble and powerful saints are qualified to handle this matter.
After everyone left, Ye Feng did not leave the mine immediately.
He jumped into the large pit of the mine and took out the transparent glass tube from the storage ring.
Buzz!
The transparent glass tube exudes dazzling blue light, and there is a vast ocean-like energy fluctuation inside.
This is all the energy of an entire mineral vein, and it is absolutely powerful to the extreme.
"Crack!"
Ye Feng's palm exploded with great force, crushing the glass tube in his hand in an instant.
"boom!"
Suddenly, streaks of blue divine light, like electric current, instantly covered Ye Feng's body, and then poured into his body crazily.
"ah!"
Ye Feng looked up to the sky and screamed. He felt that at this moment, there was an infinite current running through his entire body, and he was in extreme pain.
But Shang said that this is the fastest way to utilize the energy in the glass tube.
If it were swallowed directly, the energy of an entire mineral vein would be swallowed for who knows how long.
Ye Feng is now in this underground world and does not want to waste time.
And now he needs to quickly improve his cultivation strength, otherwise he will not be able to defeat powerful demons or geniuses from other overlord forces.
"Boom!"
Waves of blue current flowed rapidly through Ye Feng's body, surging, roaring and surging.
The ocean of mana in Ye Feng's dantian is growing rapidly.
"boom!"
"boom!"
"boom!"
Suddenly at a certain moment, three new and powerful martial arts auras burst out from Ye Feng's body.
At this moment, under the accumulation of energy from the entire mineral vein, Ye Feng actually broke through three levels in a row!
"Four times of life-threatening situations!"
"The energy in an entire mineral vein is so powerful!"
Ye Feng shouted with joy.
"Boom!"
But suddenly at this moment, a thunderbolt as thick as a barrel descended from high altitude, shattering the top of the mountain above the mine, and headed directly towards him.
"Thunder Tribulation!"
Ye Feng rushed out of the mine and came to the desert outside.
At this time, three terrifying purple thunderbolts struck down from the dark, starless sky of the underground world. The thunder clouds rumbled loudly, as if the God of Thunder was angry above the nine heavens.
Breaking through three levels at once, three thunder tribulations gathered together to obliterate Ye Feng.
Triple Thunder Tribulation!
Come together!
Overcoming three thunder tribulations at once, if this scene was seen by others, people's jaws would definitely drop in shock, because it is so crazy!
