Lao Hei's meal time was up, and he saw him coming to one of the demons. He sucked hard with his mouth and a wisp of translucent light smoke into his stomach.

Keep sucking, the size of the demon became smaller and smaller, but it did not struggle or floated there motionlessly. This shows that all its abilities were controlled by the magical power of the Immortal Prison, and even the power of screaming was ruthlessly deprived.

Looking at this scene, Su Che thought to himself: "This is called reward for one reward. The demons like to devour the souls of other creatures the most. This time, they become swallowed up by others."

Soon, the size of this demon was only a small air mass the size of a ball, but Lao Hei didn't want this remnant in the end.

Lao Hei took the initiative to explain: "Master, the purest demon power basically entered my stomach. The last remnant contained all its evil thoughts and negative emotions, which did not do anything to me, so I don't want it."

"So good?" Suche was delighted and curiously said: "You can still separate its thoughts and emotions, why can't the demon soul that was swallowed a few days ago be like this."

"This is determined by the special nature of the demons outside the domain." Lao Hei continued to explain: "The instinct of the demons is to devour living creatures, and even the same kind will devour each other. For them, no matter how much they devour, there is no hidden danger; but humans and monsters do not have this kind of talent. Even if humans and monsters practice a certain devour technique, there will still be various restrictions due to their racial characteristics. To be precise, it should be called devouring, not the true devouring."

"There is such a difference between swallowing and swallowing." Suche understood a little.

"The principle here is very complicated and cannot be explained in a few words." Lao Hei said again: "In short, if I devour the souls of humans or monsters, it will require a digestion process, but the limitation of devouring the power of the demon is much smaller."

"Okay, then you can swallow it hard." Suche smiled and said, "Your strength has improved, which means that my ability has increased."

"Okay, master."

Lao Hei walked to another demon and continued his devouring avenue.

After the two demons got drunk, Lao Hei licked his lips and touched his belly and said, "It's better to feel this way. No matter how you eat it, you won't feel overwhelmed!"

"How is it, how do you feel?" Su Che was more concerned about how much Lao Hei's strength could grow after swallowing two demons.

Lao Hei replied: "Of course it will improve. I guess if I swallow twenty or thirty demons of this level, I can advance."

"Okay, let's continue."

Su Che couldn't help but feel energetic. Lao Hei advanced to the first level again, which was equivalent to the strength of the fourth level of Qi training. With him, he could at least conspire to the opponent of the fourth level of Qi training. When necessary, he could try the fifth level of Qi training.

Next, Su Che continued to search for traces of low-level demons around the teleportation array. This vacuum zone is very beneficial to him. Within a distance of one thousand feet, the division density of demons is very low, and each time it attracts no more than three demons.

If there are less than five, there will be no danger. Su Che and Lao Hei can handle it one by one with ease.

After a few hours, Lao Hei devoured more than twenty low-level demons, and more than twenty small air balls were floating in the Immortal Prison. Each air mass was an extraterrestrial demon whose strength had plummeted to the lowest point. Their demon power was very little left, just like a newly born little boy, which poses no threat to any immortal cultivator.

So, are these demon cubs completely useless?

Lao Hei’s answer is: It’s useful, so keep it for now. Anyway, it’s just a small group of air and doesn’t take up much space.

"Master, I'm going to advance, you'd better retreat to the teleportation array." Lao Hei reminded.

Su Che understood that during the promotion process, he could not help him fight against the enemy, so he retreated under a stone pillar in the teleportation array, took out the cushion and meditated on the spot, and took the pill and started practicing without wasting any time. However, practicing in this environment requires sufficient vigilance, and the effect is definitely not as good as seclusion in a safe state.

In the Immortal Prison, Lao Hei lay on the ground like a wild beast, making strange noises in his mouth, and the surface of his body also reacted strongly. Under the gray-black fur, there seemed to be gas balls wandering back and forth...

I don’t know how long it took, Su Che, who was meditating intently, was awakened by Lao Hei’s roar in his mind. He hurriedly entered the first floor of the Immortal Prison. He saw that Lao Hei had already stood up and roared to the sky like a demon.

Not far away, Han Youming and Lu Chengan (Boss Lu), the prisoners of the Immortal Prison who were caring for more than a dozen spiritual herbs, were so scared that they squatted on the ground, hugging their heads and not daring to breathe for a moment.

These two people have been treated well by Lao Hei for a long time, and their fear of Lao Hei has penetrated into the bones. Lu Chengan has no special skills, so he can only learn the skills of planting spiritual herbs with Han Youming. At this stage, he is just a fight.

Bang!

The rat's tail blew out a crisp whip, and Lao Hei immediately reported: "Master, advance successfully!"

"good!"

Suche was very happy, but still a little greedy, and asked, "Can you continue to swallow it?"

"Not yet." Lao Hei's aura was exhaled and he said with guilt: "I'm sorry, Master, I was too optimistic before this... It turns out that although I can swallow the power of the demons, there are still bloodlines of humans and monsters in my body. If I eat too much of the power of the demons, it will lead to the assimilation of these two bloodlines by the bloodlines of the demons. In the end, I will become a real extraterritorial demon. Master, this means that you face two choices..."

"I see!"

Su Che emphasized the key point and understood that he had faced two choices at this moment, namely Lao Hei's future development direction: if he wanted to achieve a quick success, he would choose to swallow the power of the demons so that he could become a high-level demon, and even become a powerful generation of demon gods.

Suche doesn't know how much monsters there will be above the demon god.

However, Su Che believes that since the Immortal Prison Pagoda has guided him to create such a spirit of human, demon and demon clan, there must be a reason for this. If he is eager to achieve success, he will have a very likely chance of going on a detour, which is equivalent to killing the future that Lao Hei should have.

"Old Hei, infinitely devouring the power of the demon, is probably a stupid short-sighted act." Suche had already considered it clearly and said in a deep voice: "If you are so loyal to me, I must be responsible for your future. I still choose to steadily improve and protect your human and monster bloodline."

"Thank you, Master!"

Lao Hei knelt on the ground, bang bang bang bang bang bang bang bang three sounds.

This shows that he himself is unwilling to choose the path of the demon, but as a spirit of the weapon, he must unconditionally obey his master's orders, not hide anything, and not violate any of them.

"Get up, don't kneel down at any time. We won't be able to do this." Su Che said softly: "Lao Hei, although you call me master, in fact, I have long regarded you as my own relative. In this world, you are the one I trust most and closest. Perhaps, in this regard, no one can surpass you."

"Master..." Lao Hei lay on the ground and whimpered, and tears as big as beans fell quietly to the ground.

Lao Hei was really moved because he was in Suche's mind. He knew better than anyone else that Suche's words had no false elements. To be precise, this was not the "word" spoken by red mouth and white teeth, but Suche's true heart.

Then, Suche asked again: "So, is it necessary for us to continue to capture the demons?"

"Of course I have to catch it!" Lao Hei stood up and replied loudly: "And you have to catch it very hard, and catch it wildly! Master, these demons are not only a big help to me, but I just thought of a way that will also do great things to you."

"Oh, let's hear it."

"Needless to say, you will understand as soon as I do it." After the words, Lao Hei waved his hand hard, and began to encourage him like he was holding his breath...

"What are you doing? It's like constipation." Suche asked with a smile in his heart.

"Huh? No!" Lao Hei suddenly felt angry and scratched his head, "Wait, I'll try another method."

"I'm not in a hurry, think about it slowly." Suche laughed softly.

In the Immortal Prison, Lao Hei sat down for a while, stood up and walked a few steps, waved his arms, and scratched his ears and foreheads...

Half an hour passed before he shouted: "It's done!"

With his shout, Suche immediately felt a warm current flowing out from his eyebrows and began to flow throughout his body.

"Isn't it just the warm current of the Immortal Prison? What's so strange about this?"

As soon as this thought arose, Su Che realized that the so-called warm current of the Immortal Prison is the vitality of certain creatures in the Immortal Prison. So, from whom and where does these vitality powers transmitted to him come from?

"From me." Lao Hei received Suche's idea and immediately gave the answer.

"you?"

Suche said in surprise: "My health is fine and there are no injuries at all. Why do you want to extract your vitality?"

"Master, the method I thought of is to convert the excess demonic power into vitality and then transfer it to you. The effect of vitality cannot be limited to healing wounds. It can also strengthen and transform your body. The effect is definitely much stronger than pills such as marrow cleaning pills, and there will never be any negative effects. There is even reason to believe that enough vitality can wash away the drug residues in your body and remove various hidden dangers left by excessive use of elixirs. You must know that the stronger the body and the purer the physical body, the greater the success rate of foundation building will be!"

Su Che thought about it carefully and nodded, "In theory, this should be true. But will it not harm you after extracting your vitality?"

"This is my intelligence! Just now, I tried my best to think about this matter." Lao Hei raised his chest proudly: "I really came up with a good way to use the advantages of the three tribes of humans, demons and demons to transform the excess demonic power that was swallowed into the body into vigorous vitality, and then transfer it to your master. In fact, it will not consume my original vitality..."

Lao Hei explained it a lot, and Suche finally confirmed that this is a good way to benefit together.

"Old Hei, you are indeed smart!" Su Che was also very excited. Unexpectedly, he could also benefit directly from the extremely evil creatures such as the extraterritorial demons.

"Then keep going!"

Suche stood up and waved his hand with a high momentum: "Catch the demon!"
