Ron sat cross-legged in the black stone house, breathing a faint black breath, three days had passed since the last gladiatorial fight.

In the past three days, Ron has also become more proficient in the use of abyssal breathing, and has gradually been able to control the movement of abyssal demonic energy.

At the beginning, although Ron could sense and absorb the abyssal demonic energy, and he could also feel the demonic energy coiled in his chest, he couldn't control this energy.

Only the 'system' can mobilize this energy when he is on a mission, but now, he himself has gradually learned to mobilize the demonic energy in his body.

From this, he also learned why Isa's strength had skyrocketed so much when he was in the gladiatorial arena before.

Mobilize Demonic Energy for a Temporary Amplification!

Although Ron was still far from being proficient in controlling the demonic energy, he could feel that the demonic energy had a temporary effect on the physique, and for the time being, he had not yet learned it.

A trace of black qi appeared between his swallows, and it was he who was training to control the demonic qi.

........

"Knock!!" Suddenly there were two crisp knocks on the door.

"Your Excellency!" came the voice of a dwarf outside the door.

Ron abruptly opened his eyes, stopped breathing in the abyss, and muttered, "It's finally here." ”

Ron got up and pulled open the wooden door.

A dwarf about a meter tall stood outside the door, and the red sun on the horizon had only revealed a corner, and the sun had not yet reached Ron's door.

Ron looked at the dwarf in silence.

"Your Excellency, please show me your identification card. The dwarf said respectfully.

Ron nodded, took out the iron plaque and handed it to the dwarf, the number '332' on it.

"Thank you for your cooperation. The dwarf took a look and handed the iron card back to Ron.

"My lord, this is your reward. The dwarf handed out a black cloth bag, the same as the one that contained the magic crystal and the demon qi sarcoma before.

"Well, what's in there?" Ron asked as he took the bag and opened it.

"The most important thing in the reward is a tube of bloodline potion, and in addition, there are some items of demonic energy. The dwarf said respectfully.

"Blood Elixir?is this?" Ron pulled out a finger-thick sealed glass test tube from the cloth bag, which contained about ten milliliters of purple-red liquid.

There was a hint of surprise in Ron's eyes, it was the first time he had seen such a thing as a 'test tube' in this world.

Ron shook the test tube, the purple-red liquid was crystal clear, even through the test tube, Ron could feel the slight throbbing in his heart, the desire for this liquid.

"Yes. ”

"How?" asked Ron.

"Just drink it directly, the best time to use the bloodline potion is within a day, and after a day, the effect of the medicine will gradually weaken. The dwarf said.

At this time, several 'neighbors' next to Ron had already opened the door, looking at the bloodline potion in Ron's hand with greed and longing in their eyes.

"Okay! I see. Ron nodded and said, although it is unlikely that a few 'neighbors' will rob it, Ron does not like this feeling of family wealth being exposed.

"Then I'll step aside, my lord?" the dwarf asked Ron.

"Hmm!" Ron nodded.

The dwarf bowed to Ron, and then slowly stepped back.

Ron glanced at the demons next to him and closed the door with a calm expression.

In the past few days since he came, he had never seen a fight between the demons in the safe zone, and it was not that these half-blood demons were so disciplined, but that they were afraid of something.

Just like just now, the half-blood demons in front of Ron's door, the greed in their eyes had almost overflowed, but they didn't mean to do it.

No matter what those guys were afraid of, Ron didn't have the slightest inclination to try it.

Sitting on the bed, Ron took out all the contents of the black cloth bag.

Three magic crystals, five demonic sarcomas, and a tube of blood vein elixir.

Ron's magic crystals had been consumed three days ago, and there were six demonic sarcomas left, and the resources he got now were just enough to replenish them.

"Panel!"

"Power: 4.8

Speed: 1.9

Constitution: 3.6 (+0.1)

Mental Power: 2.0

Soul Points: 2.7

Aura: 19

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

........

In the past three days, Ron has not stopped cultivating in the rotten swamp. In three days, his physique increased by '0.1', and the demonic qi consumed in the rotten swamp and the demonic qi absorbed were basically equal.

After killing Issa, Ron absorbed 2.7 units of Soul Points, but instead of rushing to use them immediately, he waited for the reward from the Colosseum to see if he could make the most of his limited Soul Points.

Ron looked at the purplish-red liquid in the test tube and was about to remove the sealing plug when suddenly, he felt a powerful lifeform coming towards his quarters.

Ron paused, and after a few seconds, there was a knock on the door.

"Knock! knock!"

A smile appeared on Ron's lips, he put down the potion in his hand and got up to open the door.

"Kerry, what's the matter?" said Ron, looking at the strong man standing in the doorway.

"Ron, I told you about cultivating in the Rotten Swamp..."Kerry looked at Ron and said quietly.

"Oh, no, I feel like everyone is friendly, and except for a few people, no one is bothering me in the Poison Swamp. Ron said with a smile.

"Oh, yes, but just because you're safe for a short time doesn't mean you'll be able to go on forever. And, when I took you to familiarize yourself with the environment that day, many people saw it. Do you understand what I mean?" said Kerry, looking at Ron and calming down.

Ron's eyes narrowed, and he said after a while, "You mean, I have been able to survive safely these few days because of your strength?"

Kerry looked at Ron and didn't speak, but he didn't deny it either.

"Ha, that's really embarrassing, the next time I go to the Rotten Swamp, I'll make sure to clarify that I have nothing to do with you. Ron said lightly.

"You—"

"By the way, Kerry, I have something to do right now, and if you don't have anything else to do, so be it. Ron said, and prepared to close the door.

"Wait a minute. Kerry reached out to block Ron's door that was about to close.

"What do you mean by that, Kerry. Ron changed his previous smiling attitude, his eyes froze, and he said slowly.

"I heard that you killed Isa the other day, and the reward is here today, right?" said Kerry, in an uncertain tone.

"yes, so what?" said Ron.

"Bloodline Elixir!"

"I won't go around the bush with you, as long as you hand over the bloodline potion, you can be safe in the Rotten Swamp in the future, and I can not worry about you when you kill Isa. Ron's indecisive attitude made Kerry choose a direct showdown.

"Wait a minute, what did you just say, kill Isa, don't worry about me, what does it matter to you if I kill Isa?"

"Isa is my man!"

"Qi ~ Kerry, two days ago..."

"Don't talk nonsense!Hand over the bloodline potion, or, I'll be in the Rotten Swamp in the future, and I'll scrap you once I see you!" Kerry had lost his patience and said in a cold voice!

Ron's face turned cold, and a strong murderous aura poured out.

"Well, you can get out!" Ron said in a cold voice!

"You.."

"Get out!"
