It was still that ancient battlefield, as soon as Su Xiao arrived here, the blood of the ancient battlefield attacked him.

Su Xiao's aura was released, compared to last time, his aura was significantly stronger this time, however, the blood qi of the ancient battlefield was too strong, and his aura was not enough to completely resist these blood qi.

If Su Xiao wanted to devour these blood qi through the Devouring Core or Demon Seal, he must first have the ability to resist these blood qi.

Now he can't do anything else except keep releasing his breath, and if he loses his mind a little, he will be eroded by his blood, and once he is completely eroded, the consequences will be serious.

Blood Qi gradually penetrated into Su Xiao's breath, and these blood qi would affect his sanity and reason.

Blood-red lines gradually appeared on Su Xiao's cheeks, red light appeared in his eyes, and blood qi was rapidly eroding his consciousness.

Su Xiao tried his best to maintain his sanity, but he could feel that his own reason was gradually disappearing, if it weren't for the Soul Blade to keep him awake all the time, he would have been engulfed by blood qi, which had already broken through the scope of spiritual influence.

Just when Su Xiao was about to be unable to stop the erosion of blood qi, the light and shadow in front of him flickered, and when he returned to the skill upgrade warehouse, the blood qi in his body instantly dissipated.

[Breath Release (Passive) has been increased to Lv.3.] 】

Su Xiao leaned against the skill upgrade warehouse, panting heavily, his face covered in cold sweat.

If you want to absorb those blood qi, it is more difficult than you imagined, not to mention absorption, and now it is difficult to resist initially.

"Go on."

Su Xiao paid 30,000 Paradise Coin again, and he was teleported to the Ancient Battlefield.

Half an hour later, Su Xiao's figure suddenly appeared in the skill upgrade warehouse, his face was full of blood-red lines, his eyes flashed red, like a blood demon from purgatory, he had repeatedly entered and exited the ancient battlefield several times.

The green light dot enveloped Su Xiao inside, and the blood qi in his body dissipated.

"Ahem, ahem, ahem......"

Su Xiao let out a violent dry cough, and a drop of blood was coughed out by him, and when he entered the ancient battlefield for the sixth time, he tried to absorb the blood qi, and the blood qi got out of control as soon as it entered his body, and he didn't remember anything after that, when he regained consciousness, he was already in the skill enhancement warehouse, and his body was very heavy, like he had just recovered from a serious illness.

[Breath Discharge (Passive) has been increased to Lv.7.] 】

[Warning: The Hunter is corroded by the blood of the Ancient Battlefield, yes/no to pay for Paradise Coin restoration.] 】

"Pay."

As soon as Su Xiao's words fell, the Paradise Coins dropped at an alarming rate, and in an instant, 13,500 Paradise Coins were consumed.

"What the hell is ......"

Su Xiao couldn't help but burst into a foul mouth, the price of upgrading the 'breath release' was high, he admitted it, why was the cost of recovering from his injuries so high?

The discomfort in his body disappeared, and Su Xiao hesitated for a moment, and once again chose to improve the 'breath release'.

It was still that ancient battlefield, as soon as Su Xiao came here, he immediately sat cross-legged on the ground, subconsciously exerting his breath, using his own breath to resist those blood qi, he didn't use other abilities, and even compressed the Qinggang Shadow energy to near his heart.

He came here to increase the strength of his aura, and if he used other abilities to resist those blood qi, the Paradise Coin Flower would be meaningless.

Su Xiao had already felt that when he used his own breath to resist the blood qi, the strength of his own breath was gradually increasing.

Su Xiao's breath formed a circle, forming a five-meter-sized ball, and the light blue silk threads flashing inside were beautiful.

As time continued, sweat oozed from Su Xiao's cheeks, and his breath had been compressed into a two-meter-sized ball by the blood qi, which was about to erode into his body.

When the breath is compressed, the breath gradually becomes condensed, and the strength and quantity are increased by the external pressure.

The surrounding blood qi was not aimed at Su Xiao, they were just unconsciously eroding, even so, when the blood qi eroded Su Xiao's breath, these blood qi formed blood-red spikes and pierced into Su Xiao's breath.

A blood-colored spike gradually touched the back of Su Xiao's hand, and in an instant, blood-red lines appeared on the back of his hand and quickly spread to all parts of his body.

When the blood-colored lines spread to Su Xiao's neck, his cheeks began to twitch.

Sou~

Su Xiao disappeared into the ancient battlefield and returned to the skill upgrade warehouse.

The blood qi in his body instantly dissipated, and the blood-red lines on Su Xiao's body peeled off from his skin and quickly disappeared into the air.

[Breath Release (Passive) has been increased to Lv.8.] 】

Su Xiao's eyes opened, after some improvement, he had been able to initially resist the blood qi for a period of time, at the beginning, he would be teleported out of the ancient battlefield in no more than 5 seconds, and now, he has been able to hold on for 48 seconds.

"Just a little bit."

Su Xiao hesitated for a moment and chose to continue, although that ancient battlefield was dangerous, there were both risks and benefits.

Ten minutes later, Su Xiao, who was covered in blood-colored lines, fell to the ground, and he tried to absorb blood qi again, but still failed.

[Breath Discharge (Passive) has been increased to Lv.10.] 】

[Note: Since 'Breath Release (Passive)' has been increased to Lv.10, hunters can choose a branch reward of level Lv.10.] 】

A. Iron Ambition: Willpower +3.

B. Shura's Soul: You can mimic your own breath into a blood Shura, increasing the deterrent effect (this effect has no attack power).

C. Breath Amplification: Breath Strength +10%.

……

Three options, if it was in the past, Su Xiao would definitely choose A reward without hesitation, but this time, Su Xiao had greater ambitions.

After thinking about it for a long time, Su Xiao finally chose C reward, and the breath strength was +10%.

As soon as he completely chosen, Su Xiao's breath suddenly released out.

Rumble.

An extremely strong aura spread in the skill upgrade warehouse, and the strength of this aura increased rapidly.

After a long time, Su Xiao breathed a long sigh of relief.

"Now, maybe there's a chance."

Su Xiao took out a bottle of chewing gum, poured out one, put it in his mouth and chewed, although his mana consumption was not much, he wanted to keep his mana at full value, and the next time he entered the ancient battlefield, he would implement a plan.

"Continue to elevate the 'breath outwards.'"

[Upgrade 'Breath Release Lv.10 (Passive)' requires 50,000 Paradise Coins, yes/no payment.] 】

The corners of Su Xiao's mouth twitched, and the cost of strengthening the aura was higher.

"Pay."

The light and shadow flashed in front of him, and Su Xiao appeared on the ancient battlefield, and he was already somewhat familiar with this place.

As soon as he arrived at the ancient battlefield, Su Xiao immediately sat cross-legged on the ground, and the aura that had been raised to Lv.10 was released, and this time he was obviously more relaxed when he resisted the surrounding blood qi.

Close his eyes and perceive for a moment, under the erosion of blood qi, Su Xiao can hold on for about 5 minutes at most, time is pressing, he needs to be as soon as possible.

Su Xiao quickly converted the mana value in his body into Qinggang Shadow energy, he gathered the Qinggang Shadow energy in his hand, and compressed these Qinggang Shadow energies to a very high concentration.

The mana was quickly consumed, and after converting all the 1,200 mana points into Qinggang Shadow energy, a honeycomb-shaped ball appeared in Su Xiao's hand.

The structure of this ball is so delicate that if you look closely, you may feel dizzy.

As Su Xiao continued to inject green steel shadow energy into the ball, the volume of the ball gradually increased, from the size of a walnut at the beginning to the size of an apple.

However, this is not enough, the ball that Su Xiao made with the energy of the green steel shadow is very close to the structure of the Devouring Core, he is simplifying the Devouring Core, so that this simple version of the Devouring Core specializes in three abilities, absorption, purification, and purification.

For this simplified version of the Devouring Core, Su Xiao's focus on creating the ability is purification, the blood and qi of the ancient battlefield are too mixed, and there are many kinds of energy in it that cannot be absorbed into his own breath.

When the mana was only 300 points left, a basketball-sized simplified version of the Devouring Core floated above Su Xiao's head, he had formed a full version of the Devouring Core once, and now it was not too difficult to construct the simplified version.
