At this time, the blood qi had already compressed Su Xiao's own aura to the size of three meters, and there was not much time. He wanted to experiment as soon as possible whether the envisaged method would work.

Of course, even if he didn't succeed, with his own breath protection, Su Xiao would not be in much danger, but he would just lose some Paradise Coins.

A transparent energy silk thread is connected between the simplified version of the Devouring Core and Su Xiao, don't underestimate this silk thread, once the Devouring Core successfully absorbs the blood qi, and purifies and purifies it, the pure blood qi obtained in the end will be transmitted to Su Xiao along this silk thread.

This energy thread was created by Su Xiao for nearly 500 mana points, and there were a total of eight ultra-small devouring cores inside, and these devouring cores were simpler, and they could only have one ability, which was purification.

From the time the blood qi enters the simple version of the devouring core to the time it is transmitted to Su Xiao, it will go through a total of nine purifications, and if there is still negative energy in it, then Su Xiao will have no choice.

Taking a breath, Su Xiao activated the simple version of the Devouring Core above his head.

Dozens of small holes on the devouring core opened, like a long whale absorbing water, instantly inhaling the blood qi within dozens of meters nearby, and without the erosion of blood qi, Su Xiao's pressure plummeted.

Click......

A fine crack appeared on the simplified version of the Devouring Core, Su Xiao was not surprised, this thing was a simplified version he made, when he made the full version of the Devouring Core, he was immersed in the Qinggang Shadow energy pool, and he didn't know how much Qinggang Shadow energy was consumed.

Now that he only relied on his own green steel shadow energy, it was a matter of course that the simplified version of the Devouring Core was fragile.

After a large stream of blood gas is sucked into the Simplified Devouring Core, the Simplified Devouring Core begins to operate, purifying and purifying these blood gases.

Soon, a stream of pale red energy gushed out from the simple version of the devouring core, and at this time, the simple version of the devouring core was already blood red, and the inside was full of impurities of blood qi.

The pure blood qi was transmitted to Su Xiao along the energy thread, and the eight simpler devouring cores in the energy thread began to operate, purifying this blood qi again and again.

By the end, the blood qi had been purified to almost transparent, and only a faint red color could be seen.

Su Xiao's hand gathered a cloud of his own aura, and the blood qi that had been purified nine times merged into his own aura.

The strength of his own aura effortlessly devoured and fused the blood qi that had been purified nine times, and there was no abnormality, and when he found this scene, Su Xiao's face was overjoyed.

The initial experiment was successful, and the rest of the matter was much simpler, allowing the simple devouring core above the head to continuously devour the blood gas, and filter the blood gas into pure blood gas that could be absorbed.

Su Xiao made this kind of trick of upgrading skills, which most contractors couldn't imagine, but Su Xiao knew that he was by no means the first to do so.

The facilities of the Reincarnation Paradise are placed there, and Su Xiao spends Paradise coins to use these facilities, as for how to use them, it depends on him personally, whether he sticks to the rules or uses the smallest expenses to get a greater improvement.

What Su Xiao is doing now, the Reincarnation Paradise must have been aware of, however, he did not receive any warning, which means that the Reincarnation Paradise has acquiesced to the contractors doing so.

A large strand of blood qi was absorbed by the simple devouring core, and after several layers of purification, those pure blood qi were finally absorbed by Su Xiao.

Absorbing a large amount of these blood qi, Su Xiao didn't feel the slightest abnormality, but he just felt that his own aura was improving rapidly, of course, it was not without harm, the smell of blood on his body was even heavier, God knows if it would lose his charm attribute.

Compared to the blood qi floating on the ancient battlefield, the blood qi absorbed by Su Xiao is only a drop in the ocean, this is the ancient battlefield, the battle dead are dragons, demon goats, ancient giant beasts, and the strong men of various races, what amount of blood and qi will these people produce after death?

Ten minutes later, the simple devouring core above Su Xiao's head was full of cracks, which could be broken at any time, and the energy threads had also turned blood red, and the inside was full of blood and qi residues, which must not be inhaled into the body, otherwise there would be endless trouble.

Su Xiao breathed a long sigh of relief, there was not much time left to continue to absorb, and just as he was about to absorb a stream of blood qi for the last time, he suddenly realized that the situation around him was not right.

The blood qi of the entire ancient battlefield began to converge near Su Xiao, and if the Simple Devouring Core absorbed this amount of blood qi, it would be shattered in an instant, let alone purified and purified.

Su Xiao knew that the situation was not good, he immediately disarmed the Simple Devouring Core, and at the same time put away his own breath and let the blood qi erode him, only in this way would he be teleported back to the skill enhancement hall.

Blood-red lines appeared on Su Xiao's body.

At the same time, the blood qi in the sky above him formed a large hand that covered the sky and the sun, and this large hand was almost condensed into a solid, and the palm prints on it were clearly visible.

The blood-colored hand patted it, Su Xiao's whole body was cold, he would definitely die if he was hit by this thing, absolutely!

Boom!

A loud bang spread on the ancient battlefield, and a bottomless palm-shaped abyss appeared, and Su Xiao had disappeared.

Rumble.

A sonic boom sounded, and a man with long white hair, about three meters tall, and a withered face appeared.

The man's finger pointed at the air, the scene began to flow backwards, the palm-shaped abyss disappeared, and the figure of Su Xiaopan sitting on the ground appeared.

"Huh? Extermination? “

The white man's pupils shrank, and his face was as cold as a dead wood.

"Did it appear again, since I met it during the formative period, then turn it into a corpse."

Seeing no movement, the space in front of the white-haired man shattered, and he walked into the void and began to track Su Xiao.

Two seconds later.

Bang!

The space shattered again, and the white-haired man, who had been twisted and deformed, flew out of the hole in the space and fell to the ground.

"What is this existence? What a great ......"

The white-haired man's lips trembled, as if he had seen some terrifying existence.

Zheng!

With a crisp slashing sound, a spatial crack appeared, and a humanoid creature with blue smoke floating through its body and holding a long knife walked through the crack.

"Who is this? No, it's a knife ......"

Brush~

The white-haired man's head flew up, and the humanoid creature covered in blue smoke stared at the white-haired man's corpse, and after a long time, he turned and entered the spatial rift.

"Kind, where are you, let me... Kill you. ”

The voice of the humanoid came from within the cracks in the space.

A few minutes later, the spatial holes and cracks in the ancient battlefield healed.

……

In the skill upgrade warehouse, Su Xiao was lying on the ground, covered in blood, and he might be unconscious at any time.

That blood-colored palm didn't hit him, even so, he was still seriously injured, which made him secretly vigilant, he must not easily enter that ancient battlefield in the future, there are too many unknown factors.

[Warning: The hunter is eroded by the blood and qi of the ancient battlefield, has multiple fractures on the body, severe internal bleeding, and a trace amount of blood and gas residue mixed into the breath, yes/no to pay for the recovery of Paradise Coins.] 】

Su Xiao's eyes narrowed, even if he used multi-layer methods to purify his blood qi, his breath was still mixed with blood qi residues, but fortunately, he could use Paradise Coin to remove it.

"Pay."

As soon as the words fell, Su Xiao felt a pain in his flesh.

[Hint: It costs 10,600 Paradise Coins to clear the blood gas erosion,]

[Hint: Multiple fractures and severe internal bleeding on the body need to consume 1300 Paradise Coins.] 】

[Hint: Removing the blood residue in the breath costs 47,200 Paradise Coins.] 】

[The payment of Paradise Coin is completed, and the repair begins.] 】

……

An hour later, Su Xiao looked at the only remaining 35,800 Paradise Coins, and he couldn't help but sigh, the Paradise Coins were spending too fast, and the remaining Paradise Coins were to be used to make No. 1 Elixir.

Although he spent a lot of Paradise Coins, these Paradise Coins, which were worth it, immediately opened the list of skills and checked the breath release.
