Half a month later.

"Bang!"

A young figure of a green-robed monk appeared on the side of a huge lava pool under the bottom of the submarine volcano.

This once lively Earth Fire Cave had been carefully searched by the ancestors of Tianque City after experiencing the rebellion of the Fire Clam Demon Ancestor, but now it is empty and dead again.

No one would come to this place, and it was just right for him to "refine" the three demon ancestors.

He took out a mouthful of the treasure gourd that bloomed with cyan brilliance from the sleeve of his wide robe, threw it into the air, and flew above the magma pool filled with intense flames.

The mouth of the demon gourd opened, spewing out bursts of blue light.

"Come out!"

Su Chen drank lightly.

"Whoa~!"

The Fire Clam Demon Ancestor was the first to roll out of the demon gourd, and the "poof" fell into the lava pool, splashing several feet of waves.

Its huge, shriveled toad body was covered with scars left by various whips, fires, and freezing, and it was almost tortured half dead in just half a month.

"It's so comfortable!"

The Fire Clam Demon Ancestor returned to his lair and floated in the molten pool, feeling the omnipresent and fiery aura around him, which was extremely comfortable.

It is a fire demon ancestor.

Instead of burning its demon body, the boiling hot lava liquid provided it with extremely precious fire aura, allowing it to take a breath and absorb foreign fire aura from its extreme lack of demonic power, and recover a little.

But it will take at least a few months to fully recover and heal from the injury.

Subsequently, the demon snake body of the Red Refining Snake Demon Ancestor, which was more than ten zhang long, and the dilapidated demon body of the Flying Rat Demon Ancestor, all fell into this lava pool.

The two demons were not fire-type demon beasts, but they couldn't stand the hot molten liquid of this lava pool. In the magma pool, the skin of the demon's body was burned, the meat was almost cooked, the bones were exposed, and they all screamed "wow".

Su Chen threw their three Demon Ancestors into the bubbling pool of hot magma and soaked them.

In the past half a month, he used the demon gourd to take the three wild demon ancestors to various dangerous places that could be found within a million miles around Tianque City, and took the cold water, blazing fire, strange poison, and even heavenly thunder between heaven and earth, etc., and "tortured" the three demon ancestors for a long time.

In order to resist all kinds of blows, they had already exhausted most of their demonic power and physical strength, and they were tortured to a half-dead, almost unable to move their fingers.

Now that Su Chen released them from the demon gourd and threw them in the molten pool, they had long since lost the strength to escape. Even if the three demon ancestors of them combined, they couldn't beat him with a finger at this moment.

Su Chen looked at the three demon ancestors in the lava pool, and thought in his heart, how could he submit their three demon ancestors to become the three demon ancestor-level demon slaves loyal to him.

He had put a lot of effort into "refining" them, but it didn't seem to be working well.

The two demon ancestors of the Fire Clam and the Flying Rat had not used torture much every time, so they kept shouting, begging for immediate submission and surrender, and let them go east, and they would never go west.

These two demon ancestors took the initiative to submit too quickly, so that they couldn't distinguish the truth from the fake, were they really willing to surrender, or did they pretend to surrender?

Even if it is a Jindan demon general, it usually takes several years of refining.

What's more, it's the Yuan Infant Demon Ancestor.

It had only been half a month since he had "refined" the three demons, and he naturally didn't dare to easily believe that they were truly subdued.

Only the Red Refining Snake Demon Ancestor is still the same old man, with an extremely hard mouth, clamoring to chop alive and just come to it, wanting to make it submit to no way.

Su Chen stood on the edge of the lava pool, looking at the Fire Clam Demon Ancestor with a satisfied expression, while the Red Refining Snake Demon Ancestor and the Flying Rat's Ancestor were struggling in the lava pool.

"The effect of 'grace and power' is not obvious. Could it be that he really needs to find the Yuanying-level beast control technique in order to refine these three demon ancestors?"

Su Chen was a little skeptical.

He had seen in some high-level beast control classics that some records said that there was a high-level beast control technique called "Soul Extraction", which could control demon slaves almost absolutely.

The principle of this technique is that any primordial spirit is divided into three souls.

This beast control technique can control the demon slave by stripping off a complete "Demon Cultivation Yuan Infant", extracting a wisp of spiritual wisdom yin soul out of the three souls, and imprisoning it beside him.

If the demon slave betrays and destroys this wisp of yin soul, the demon ancestor will immediately become a fool and lose his wisdom.

This method is absolutely good, unless the demon slave dies, he will hardly risk becoming a fool and betraying his master.

"Soul Extraction" is extremely difficult and costly, and it is only suitable for dealing with demon ancestors above the Yuan Infant level.

This "Soul Extraction" used to be one of the most effective beast control methods to deal with those high-level demon clans.

All this would have been fine.

But the problem is that this soul extraction technique is effective for all primordial gods, not just for demon ancestors. This also means that it is not only useful for the demon infant of the Demon Ancestor, but also on the primordial infant of the Terran Ancestor.

Because of this, there was a big mess.

Tens of thousands of years ago, there were some immortal cultivators in the Beiming Continent who unscrupulously abused this technique, using the soul extraction technique that was originally used to control the demon generals to imprison and enslave the Terran monks, and even evil cultivators used it to coerce other ancestors to rebel together, trying to replace the Tongtian Dynasty.

The Tsuten Dynasty suffered greatly from this, and after a great upheaval, it was forbidden to use such secret arts, and no beast master monks were allowed to use them.

Once this technique is used, it is classified as an evil cultivator and can be killed.

After tens of thousands of years of destroying the Soul Extraction Classics and hunting and killing evil cultivators, the beast master who mastered this Soul Extraction Technique completely disappeared and was never seen again in the Beiming Continent. Nowadays, almost no monks have mastered this technique, and only a few of the beast-mastering texts are left that mention it.

This was also the reason why Su Chen did not find this spell in the Tianque City Classics Merchant Pavilion.

"Old Ancestor Su, master, my Flying Rat is willing to surrender~! Let me go out, if I continue to cook, I will die." ”

The flying rat fluttered and struggled in the molten slurry, and the meat on its body was almost cooked, and it couldn't help but scream bitterly.

Among the three demon ancestors, its strength is the weakest, and it can't bear it the fastest. It is really about to collapse its will, as long as it can let it go, it can agree to any condition.

"I... I am willing to surrender!"

The fire clam groaned in comfort.

Although it returned to the lava pool, it would take at least a few months to recover from its injuries. Before that, he couldn't win against Su Lao Zu at all.

It has given up the idea of running for its life.

Of course, Su Chen hoped that they would be able to submit to him sooner, but the premise was that they had enough loyalty, otherwise they would suffer from it.

He shook his head, "I arrested you, of course, for the purpose of hoping that you three demons can become my demon generals and serve me loyally." But you say that you are willing to submit, but you lack sincerity in action, and I cannot believe you!"

"Master, how can you show your sincerity in submission?"

The Flying Mouse said bitterly.

"Don't ask me. Think for yourselves what you should do to show that you are truly obedient and loyal to me! ”

Su Chen said with a smile.

Anyway, he was not in a hurry, and he had plenty of time to refine them. If they are unable to show their loyalty, they continue to "refine" until their will is completely broken.

The Flying Rat and the Fire Clam Demon Ancestor were both stunned and looked at each other.

They have to prove their loyalty to themselves before Su Chen will accept them?

This is to ask them to show their pledge of allegiance... He would have believed it!

Su Chen said lightly, "If you can't prove that you are sincere and obedient, then I can only use the last resort." I once saw a high-level beast mastery technique, "Soul Extraction", which extracts a wisp of your Yin Soul from the demon infant and seals it in the demon gourd to ensure your loyalty. At that time, don't blame me for being ruthless!"

"This..."

"This soul extraction technique is too ruthless!"

When the flying rat and the fire clam heard this, their faces suddenly changed drastically and they shuddered.

They have some thoughts in their hearts waiting for an opportunity to escape.

But if Su Chen extracted a wisp of Yin Soul from their demon baby!

In this way, won't they be slaves all their lives, and they don't even dare to have the mind to escape?

Not to mention the yin and yang are against the master!

The Red Refining Snake suddenly snorted: "Two demon brothers, don't listen to him to scare you! This ancestor is well-informed and knows some of the great laws of the dynasty, and this soul extraction technique has long been banned by the Tongtian Dynasty.

If he dares to use it, it will be a blatant disobedience to the imperial ban and will be hunted down and killed by the Terran Ancestor. When the time comes, it will be known by other ancestors that there is no need for us to do anything at all, and the Beiming Continent will not be able to tolerate him. ”

Su Chen couldn't help but look cold, and glanced at the Red Refining Snake Demon Ancestor.

This little demon snake really dared to do anything with him, and he actually dared to expose him, he was tough enough, it seems that he has not been "refined" enough. Refine it for a few more months.

The fire clam and the flying rat breathed a sigh of relief at the same time.

It turned out that Su Lao Zu was scaring them, and most of them would not really draw their ghosts out.

But even if Su Chen doesn't use this technique, they still have to think of ways to prove their loyalty before they can come out of the demon gourd.

Otherwise, they will not be able to survive the suffering of this refining day and night.

A flash of inspiration flashed in the Flying Mouse's mind, and he thought of a brilliant idea, and hurriedly said eagerly, "Master, I can show you my absolute loyalty with my actions! Originally, we were the Six Demon Ancestors who went to Tianque City together to find trouble for you. The three demon ancestors of the Red Fire Scorpion, the Gray Crow, and the Vulture have fled, and I know where they are, so I'll take you to catch them!

The Fire Clam Demon Ancestor couldn't help but be stunned, extremely remorseful.

Why didn't it think that there was still this method available! Although betraying the demon brothers is not righteous, there is a saying.... Dead friends do not die poor.

The Red Refining Snake Demon Ancestor was even more unbelievable... This Flying Rat Demon Ancestor actually wants to betray the other three demons, won't he really give in, and plan to sell his life to Su Chen as a demon slave, right?

Su Chen's heart moved, and after a little thought, he couldn't help but smile with satisfaction, "Okay! Flying Mouse, your move is indeed full of sincerity." As long as you take this ancestor to catch the other three demon ancestors, I will believe that you are truly obedient and will no longer refine you!"

Even if the Flying Mouse is pretending to surrender this time, he will find an opportunity to slip away in the future. But as long as you catch those three demon ancestors, it will definitely be a good deal to earn three for one.
