More than thirty hours later, the sound of mission completion sounded.

Ron, sitting cross-legged on the stone bed, opened his eyes.

"Panel!" Ron muttered.

Abyssal Lungs Cultivation Plan: Stage 1: Absorb Rotten Qi through the mouth and nose (use the Abyss Breathing Method), and ingest at least 1 unit of Rotten Qi for each breath (can be interrupted). Consumes 50 soul points and 150 abyss demonic energy.

Stage 2: Absorb Rotten Qi through the mouth and nose (using the Abyss Breathing Method), ingest at least 5 units of Rotten Poison Qi per breath for 30 days (can be interrupted), consume 210 Soul Points and 9500 Abyss Demon Qi.

Stage 3: Unknown!(Consume soul points to continue the deduction!)

Stage 4: Unknown!

Stage 5: Unknown!

..........

Ron looked at the cultivation plan deduced by the Black King on the panel, and spent more than ten soul points, but he actually only deduced part of the cultivation plan, looking at the content on the panel, there were at least three stages of cultivation plan.

"But for the time being, that's enough. Moreover, the cultivation plan of the Abyss Law consumed more soul points than I expected. Ron thought to himself.

........

Poison gas must be ingested through the nose and mouth, and at least one unit of putrid gas must be ingested per breath. Natural conditions are definitely not satisfied, even in the depths of the Rotten Swamp, it is impossible to reach the concentration of one unit of Rotten Poison Qi per breath.

In this case, Ron would have to create his own cultivation environment.

In the Rigal swamp, after the demon clan's body was strong to a certain extent, the first thing that came to mind was not to take the poisonous beast poison sac to enhance the effect of poison gas refining body.

Because of the inertia of thinking, the first thing that most demons think of is how to turn the poisonous beast's poison sac into gaseous poisonous gas, increase the concentration of rotten poisonous gas in the air, and directly take the poison sac is derived after the demons' demand for the effect of toxic substances further increases.

.........

Rotten swamps.

Ron sat on the massive obsidian with Lawrence standing beside him.

When Ron walked to Kira's stone house, he found that his demonic qi fluctuations were not normal, probably taking a third-class bloodline potion, and the effect of the medicine was working, so Ron called Lawrence instead.

Ron's body didn't completely fill the obsidian, probably about two-thirds.

In the remaining places, a small flame is burning.

"My lord, can you begin?" asked Lawrence respectfully.

"Let's get started!" Ron said, nodding.

Lawrence nodded, respectfully walked over to Ron, and took out a black cloth bag.

Lawrence carefully opened the cloth bag, which contained a slow black powder, Lawrence carefully twisted out some of the powder, and bent down to sprinkle it over the flames.

The red flame instantly turned dark red, and a cloud of black smoke slowly rose from above the flame.

"Suck ..... Whew—" Ron took a deep breath and inhaled a puff of black smoke into his body.

"Ingestion of putrid gas: 1.6. ”

"Suck..."

"Ingestion of Putrid Gas: 2.7"

........

"Ingestion of Putrid Gas: 0.9"

This method didn't have a high utilization rate for poison sac powder, but it was the most suitable way for Ron to cultivate the Abyssal Lungs.

It is unrealistic to directly absorb the poison sac powder through the nose, not to mention whether the venom powder can enter Ron's lungs in this absorption method, in terms of this way of consumption, although there are many poison sacs in Ron's hands now, it can't support the consumption of this way.

After about ten minutes, the effect of the pinch of black powder dropped to the point where each breath was less than 1 putrid gas, Ron frowned, and slowly opened his eyes.

After a moment of silence, Ron said to Lawrence, "Wait a minute, look at the fingers of my right hand, I will move my fingers, and you will sprinkle a pinch of poison sac powder into it." Got it?"

"Understood!" Lawrence said.

"Okay, go get some more firewood now. Ron said.

"Yes!" With that, Lawrence turned and left.

Ten minutes later, Lawrence returned with a large bundle of firewood, and then Ron's Abyssal Lung cultivation officially began.

"Boom...."Lawrence sprinkled a pinch of powder into the flames.

Seeing the black smoke rise, Ron slowly closed his eyes.

"Suck .... Call... Suck it"

"Ingestion of Putrid Gas: 2.1"

.........

"Activate the Abyssal Lungs cultivation plan!" Ron said silently in his mind.

"The task has been accepted.... Analyzing...."

"The Abyss Lungs cultivation plan, the first stage consumes 50 soul points and 150 abyss demonic qi, and if the cultivation conditions are met, do you want to start immediately?"

"Yes!"

...........

After a while, Ron felt a very strange sensation rise in his chest, like a flame, scorching, and like many ants eating his body, it hurt, but it didn't exceed Ron's tolerance limit.

And, as he exhaled and breathed, the strange pain shifted between intensifying and weakening.

After a few moments, Ron felt that the poison gas from the outside world was slowly weakening, and Ron moved the fingers of his right hand before the gas effect fell below the limit he needed.

The concentration of the poison gas slowly rose again.

In this way, with the assistance of Lawrence, Ron cultivated the lungs of the abyss day and night.

He was two months away from leaving the Rigar Swamp, and before that, Ron wanted to cultivate the Abyssal Lungs to the next level as much as possible.

..........

After eleven days, Ron finally completed the first stage of cultivation of the Abyssal Lungs.

Because of the addition of firewood in the middle, Lawrence was allowed to rest properly, and the ten-day period was extended by one day.

On the boulder, Ron slowly opened his eyes. A small ball of firewood slowly burned in front of Ron, and Lawrence stood behind the flames, staring at Ron's hand.

"Thank you!" Ron said.

"It's an honor to serve adults!" Lawrence said.

"Alright, it's over, you can go back and rest!" Ron said.

"Yes!" Lawrence bowed slightly, and then left directly.

Lawrence doesn't think as much as Kira, so there are some things that Lawrence is better suited to do than Kira.

Everything is difficult at the beginning, and the same is true for the cultivation of the Abyss Lungs, it is very troublesome at the beginning, and you still need someone to help, but as long as you enter the door, the rest is much simpler. Of course, simple is just a step, and the difficulty of cultivation will only get greater.

.........

In the midst of the poisonous beasts, Ron stood in the middle of a clearing, surrounded by spears, where Ron often practiced his spear throwing.

"Whew....." Ron let out a long exhale.

Plumes of black smoke came out of Ron's mouth and nose, long strips of black smoke like a black rope, one end connected to Ron's mouth and nose, and the other end was wrapped around Ron's body under Ron's control.

Ron let out a long breath and the length of the black smoke continued to grow.

Suddenly, the black smoke that connected Ron's mouth and nose finally stopped, and Ron's long breath was finally over.

Circles of black smoke wrapped around Ron's body, from his feet to his neck, but in reality, the black smoke did not touch Ron's body.

"The black smoke from the first group of demons I met was because I cultivated the lungs of the abyss, right?" Ron thought to himself.
