"How about a magic crystal?" Ron said.

"What?"

"Remuneration. ”

"Of course, if you will. By the way, I also provide Rotten Swamp Cultivation Shelter, if you need it. ”

"I'll look for you if you need to. Ron said.

"Of course. ”

"By the way, was that guy from yours before?"

"Who? Issa? Of course not. Kerry shook his head.

A cold glint flashed in Ron's eyes, and he had already come up with an answer.

"That's good.," Ron nodded.

"By the way, you said that the gladiatorial arena has special rules, what are the rules?" Ron asked

"Hey~" A strange smile appeared on the corner of Kerry's mouth, and he paused before saying: "Kill the opponent, hand in the corpse, and the Black Tower will give a reward." A very precious reward. ”

........

Ron stayed in the Colosseum until late in the evening before returning to his lodgings, and Kerry followed Ron back and took his pay.

After Kerry left, a cold glint flashed in Ron's eyes.

He knew that Kerry was in the same league as the previous Issa, but before he knew their strength, Ron could only endure it for the time being.

At night, Ron meditated until late at night, and only fell asleep when he was very mentally exhausted.

The next morning, Ron got up early, ran around the Black Tower twice, and came to the Poison Mist Swamp area.

After a moment's hesitation, Ron slowly stepped into the area of the Rotten Swamp.

"Suck...."

"Ahem. . . Ahem..."Ron suddenly coughed violently, and the poisonous gas entered his body, instantly causing Ron's discomfort, colic, numbness, and slight convulsions.

Ron's change instantly attracted the attention of the surrounding demons, many eyes looked at it at once, most of them just glanced at it and then withdrew their gaze, but there were also a small number of them who stared at Ron for a long time before slowly retracting their gaze.

"Unknown active substance detected, abyssal demonic qi detected..."

"Named the Rotten Miasma. Ron muttered.

"Naming done. ”

"Monitor the effects of the putrid miasma. Ron ordered.

"Monitoring... How long it will take is unknown.."

Ron sat down cross-legged and began to breathe slowly in the swamp air, although it was still uncomfortable, Ron held back and never made a fool of himself again.

After more than an hour, perhaps having adjusted to the effects of the poison gas, Ron's spirit gradually relaxed.

Immediately, Ron was about to adjust his breathing to breathe in the abyss, but he used a special breathing method, and another intense pain hit him.

Ron's body tensed, his muscles bulged, and the demonic energy in his body worked automatically, slowly repairing the body that had been damaged by the poisonous gas.

Until the evening, Ron did not succeed in transporting the abyssal breath, but his body was destroyed by the poisonous gas.

Ron got up and left the Rotten Swamp area, and if he continued, he was almost incapacitated, and if the demonic energy was exhausted, it was not impossible to be poisoned here.

Ron dragged his scarred body back to his lodgings, sat cross-legged on the bed, and opened the properties panel.

"Power: 2.0 (4.7)

Speed: 0.9 (1.9)

Constitution: 1.8 (3.3)

Mental Power: 1.7 (2.0)

......

"It's... Brutal way of evolution. Ron muttered with a wry smile.

Immediately, Ron closed his eyes and began to breathe into the abyss.

"Whew. Suck... Whew.." There was no putrid gas in the air, and Ron quickly got into a state and began to absorb the thin abyssal demonic energy in the air.

Little by little, the night came. Suddenly, Ron opened his eyes.

"No... The abyssal demonic energy in the air was too thin. The absorption rate is too slow. Ron muttered.

After he came back, he began to breathe in the abyss to replenish his demonic qi, but until now, his demonic qi value has not only not increased, but has decreased by four points, and on the contrary, his physical fitness has also recovered by half.

"It seems that we can only use magic crystals. Ron thought.

It seems that those six magic crystals are not only used to learn abyss breathing, but also to learn to breathe abyssally in the rotten area, otherwise, it may slow down the evolution.

"Bang. Ron smashed a magic crystal, and the rich abyss demonic qi seeped out.

"Whew. Suck ..."

........

When dawn came, the first rays of sunlight shone in, Ron slowly opened his eyes.

"Ding! mission accomplished. ”

"Putrid gas: damage, damage and destruction of cell structure, after repair, cell activity is slightly improved. Subtle improvement in cell anti-toxicity properties. ”

"Power: 4.7

Speed: 1.9

Constitution: 3.4 (+0.1)

Innate Abilities: Soul Absorption, True Self Consciousness, Body Imprint"

.......

"This way of evolution, a powerful racial talent. Ron sighed.

This time, he knew the amount of demonic energy contained in one magic crystal, and each magic crystal contained about twenty units of demonic energy.

After recovering from his body, Ron returned to the Rotten Swamp.

Although the Rotten Swamp allows for fighting, few people will actively make enemies unless they are hostile or motivated by interests. Moreover, you don't know who is paying the 'protection money'.

The second time he came to the Rotten Swamp, it took half a day for Ron to finally sense the existence of far-reaching demonic energy. With the first wisp of abyssal demonic qi he absorbed, in his rotten swamp, it was finally not a state of attrition of 'going out and not entering'.

Time passed slowly, and Ron's abyssal breathing became more and more proficient, but overall, it was still in a state of consumption.

"Bang!" Suddenly, a kick landed on Ron, who fell to the ground on his back.

"Ahem.." Ron was suddenly attacked, his breathing in the abyss was interrupted, and he inhaled a large amount of poison gas, and coughed violently.

"Boy, I've finally found you," an arrogant voice sounded.

“.. Ahem.. You're looking for death!!" Ron looked at the man in front of him, a chill flashing in his eyes.

This person is the same person who troubled him two days ago.

"Looking for death!?" Issa's figure flashed, and instantly appeared next to Ron, kicking Ron in the face.

"Bang!" Ron raised his hand, barely blocking Issa's leg, he was now in a weakened state, less than half of his strength.

With a backhand, Ron tried to grab his opponent's leg, but Aisa's reaction speed was much faster than Ron's, and his leg shrunk as his other foot flew into the air and kicked Ron to the waist.

Enduring the severe pain, Ron violently erupted and pounced directly on Isa.

The timing of Ron's outburst was so good that Isa hadn't retracted one foot before the other hit the ground, and even if he could react, he couldn't dodge it.

Isa's pupils dilated, and a hint of horror flashed in his pupils, and Ron's hideous face was reflected in his pupils.

Just as Ron was about to pounce on Esa, his body suddenly spasmed, and his momentum instantly dissipated, and he fell to the ground suddenly.

After a pause, Isa reacted, and then, a fire of annoyance burned his reason.

"You—" Isa was about to get angry when a dark shadow flashed in front of him.

After a few movements, Ron was back in the safe zone.

"Do you think I won't be able to move you if I hide in the safe zone? Isa exasperated and exclaimed.

"Ahem... It's up to you, and you're not worthy!" Ron said, clutching his chest, a little weak.

"Your name is Issa, isn't it?"

"Boy, you're dead, no one has ever dared to say that about me. Isa didn't answer Ron, and slowly stepped into the safe zone.

"How's that to say? A dog. Ron said disdainfully, his gaze wandering around, as if searching for something.

"Bastard..."

"Alright... Isa, I'm going to fight you. Ron didn't give the opponent a chance to continue barking.

"Fuck you... What?gladiatorial fight?are you sure?!" There's a look of surprise in Issa's eyes.

"Tomorrow, when the first rays of the red sun shine on the Colosseum, will you dare to come?" said Ron, calmly.

"Good, good... Boy, you're looking for your own death. Aisa said in a cold voice, the surprise in his eyes had overflowed on his face.

......

After saying that, Ron stopped talking and turned to leave.

In his eyes, there was a twinkle of the data he had just captured.

"Unknown target

Power: 1.6

Speed: 3.1"

......

This is just what Isaac showed just now, and it is not necessarily the limit.

But judging from the situation just now, Ron is almost certain that this is at least more than eighty percent of Isa's strength, and even if there are reservations, it is definitely not much.

In his previous life, as a legendary scar master, Ron didn't know how many battles he had experienced in his life, but he still had this eyesight. In the battle of the previous life, especially when he was besieged and chased in the end, it was almost the cooperation of the world's Magnitary and modern technological weapons that brought together him with great difficulty to kill him after paying a heavy price.

When he pounced just now, Ron actually made a deliberate mistake, in the rotten swamp, he couldn't kill the opponent, but he didn't want to scare away the prey, so he thought of showing weakness to the enemy.
