The black, stone-like thing that suddenly appeared was the magic core that Tu Ming was bidding for in the auction house, and at that time, Li Qian'er was still in the limelight, and she scared off the martial artists who were bidding with her.

Dong Lao also mentioned that the Demon Gathering Core is a peerless treasure used by demon cultivators for cultivation, which can collect and purify demonic qi and can be absorbed without refining.

Tu Ming threw it in the space in his body under the auction, and he had long forgotten it, but he didn't expect to be affected by the demonic qi outside his body, but he jumped out.

The demonic qi was attracted by the demon core, Tu Ming's pressure dropped sharply, and he hurriedly swallowed a bottle of Purple Emperor Liquid to drive the star refining technique, restore the trauma of the body, and expel the demonic qi in the body.

As the Demon Gathering Core continued to collect demonic energy, a layer of pitch-black shield appeared on its surface, this layer of shield was pure in energy, without a little negative energy, just a little cold.

Tu Ming was wrapped in it, feeling much better, and with the operation of the Star Refining Technique, a considerable part of the purified demonic qi was also absorbed by him, circulating in his body, gathering the chaotic demonic qi scattered throughout his body, and slowly purifying it, making his recovery even faster.

Tu Ming felt much better, and hurriedly poured two more bottles of Purple Emperor Liquid to completely remove the demonic qi in his body, and the corroded muscles on the surface of his body gradually returned to their true colors, and the injuries also recovered at a speed visible to the naked eye.

"Bang Bang ......"

Those demon soldiers finally approached Tu Ming, and they all raised their bone knives and slashed at the pitch-black light mask, but as the attraction of the demon core became more and more attractive, these demon soldiers were also sucked into the demon core.

"This ......" Tu Ming, who was looking at this scene, showed a look of surprise on his face, it seems that the Demon Gathering Core can not only collect and purify demonic qi.

Although I don't know if these demon soldiers will be refined if they are sucked into the demon core, at least Tu Ming's immediate crisis has been solved, and soon more than a hundred demon soldiers will be sucked into the demon core.

Outside of the demonic qi, the bell was sitting cross-legged on the side at this time, holding a fist-sized pitch-black magic bead in his hand, and the demonic qi was emanating from it.

This magic bead was obtained by Diao Zhong from the Inheritance Cave Mansion, and a huge amount of demonic qi was gathered in it, which was exactly what he usually used for cultivation, and now he released a part of it, relying on the Demon Dragon King's martial soul, forming a terrifying attack, which put Tu Ming in a predicament.

These demonic qi are still ownerless, and his Demon Dragon King Martial Soul can only control it, as for the demonic qi mutated by the assimilation vines, it needs to be collected into the magic bead, and he can slowly absorb and refine it before it can be used.

But even so, it has brought a great crisis to Tu Ming, if it weren't for the Demon Gathering Core, the consequences would be really hard to say.

"Hmm, what's going on?" the bell suddenly screamed, and he found that the demon clouds in front of him were not only not increasing, but gradually decreasing, and the speed of reduction was getting faster and faster.

"Hurry! stop him for me!" Demon Zi Zhong sensed carefully, his face changed greatly, and he found that the demon clouds were all gathered in the direction of Tu Ming, where there seemed to be a bottomless pit, constantly devouring the demon clouds, and all the demon soldiers that appeared before had also disappeared.

"Boom ......"

The Martial King powerhouses gathered their energy, and one by one the pitch-black handprints appeared, imprinting in the direction of Tu Ming.

"What's that?" Through the tumbling demon cloud, they finally saw the scene in the demon cloud, a pitch-black black object was devouring the demon cloud, and there was also a layer of pitch-black shield, but Tu Ming's figure disappeared.

"Grab that thing for me!" Demon Zi Zhong looked at it, and was shocked, this thing was what Tu Ming bid for at the auction, and there was a small episode at that time, he also thought that a certain little girl was playing willfulness and smashing people with spirit stones, but he didn't expect that the auction was actually a treasure who collected demonic energy.

The magic bead in his hand is actually the demon core of the Demon Dragon King, and the demonic energy in it is used a little less, and the demonic energy of the non-Demon Dragon King cannot be absorbed, once the demonic energy of the magic bead is consumed, his cultivation will be affected.

And the things that Tu Ming auctioned were obviously more valuable than the magic beads, and he could actually collect demonic energy, how could he miss such a precious thing!

He was very remorseful in his heart, when he was bidding, his martial soul fluctuated, but he didn't take it seriously, he didn't expect to miss such a good treasure.

However, these Martial Kings were not his subordinates, and it was impossible for them to burrow into the demonic qi to snatch the Demon Gathering Core for him, so they only kept attacking all around, trying to knock it out.

However, the demonic qi is too terrifying, and the attack they launched will not be close at all, it will be corroded and assimilated by the demonic qi, and become a part of it, and the attack will have no effect.

"No, I must get this thing!" Seeing that their attack was ineffective, he didn't dare to step into the demon cloud, he turned his head behind him and said, "Old Xu, it seems that I have to ask you to make a move!"

"Hehe, it's okay, I'm also interested in that thing! Let me come!" I saw an old man slowly appearing, nodding slightly to the Demon Son, his body flashed, and he rushed into the Demon Cloud.

"Huh!" The old man who was called Xu Lao by the bell had just stepped into the thick fog, when suddenly a sharp sound of breaking the air came, and an arrow came straight towards his front door.

"Hmph!" Xu Lao snorted coldly, raised his hand, grabbed the iron arrow in his hand with a "snap", and threw it back the same way.

"I'm grass!" Tu Ming was shocked, he didn't expect this old guy's strength to be so terrifying, and he could catch his bow and arrow with his bare hands.

Seeing the iron arrow shooting towards him, Tu Ming took out the foreign earth stone slab and erected it in front of him, and at the same time reached out and grabbed the demon core in his hand.

With a "bang", the iron arrow hit the stone slab, and the huge impact force made the iron arrow split, and the stone slab smashed head-on Tu Ming's body, throwing him away, and then spitting blood from his mouth, and his internal organs were almost shattered.

"Not good!" Tu Ming screamed, watching the old man pounce on him with a hideous face, reaching out to grab him by the neck, Tu Ming didn't dare to attack him, and the life-devouring demon soul jumped out of his body and pounced on the old man.

The old man surnamed Xu was stunned, and then his soul seemed to be in sharp pain as if he was being Ling Chi, and he let out a "snort" and hugged his head and shouted.

"Fuck your uncle!" Tu Ming was almost suffocated to death, he had never been so passive in battle all this time, and he was so pressed that he almost couldn't raise his head.

"Whew!"

Tu Ming took the foreign soil stone slab and covered it.

"Ahh

"Ahhh......h

The old man surnamed Xu was slapped to the ground fiercely, letting out a terrible scream, his two arms were broken alive, and Tu Ming was also hit by a huge force and flew out with his head, spurting blood in the air one after another.

"Ahh......hh

The old man's screams became more and more miserable, and his soul and body were destroyed, which he could never have imagined no matter what, and Di Zhong was even more unexpected, he was close to the existence of a high-level soul king, and he actually suffered under Tu Ming's hands, which made him feel a huge wave in his heart, and he felt more and more that he had to get rid of Tu Ming.
