"Have you heard of or appeared in the Nine-Leaf Demon Soul Grass over the years?" Ling Tian suddenly asked.

"Nine-Leaf Demon Soul Grass?"

Cook, Louis and the others all looked at each other curiously, they seemed to be very unfamiliar with the Nine-Leaf Demon Soul Grass.

"I don't think you know. Ling Tian shook his head helplessly.

"If the adults want it, I will definitely gather people to help the adults find it!" Cook hurriedly said in an almost flattering allegiance.

"Okay! I want it now, and as soon as possible, so you gather all the Hell Demon Clans in the entire underground battlefield, pass on my orders, and find the Nine-Leaf Demon Soul Grass at all costs, this emperor has a heavy reward!" Ling Tian said coldly.

Cook and Louis hurriedly knelt on the ground to answer the order.

The news of Ling Tian's return was quickly passed out, which made the demon who knew Ling Tian's power tremble, and Ling Tian, the invincible Great Demon King back then, was back.

Countless demons began to search for them throughout the underground battlefield.

This time was different from the past, at the beginning, Ling Tian personally led 100,000 demons to search for treasures in the underground battlefield, and almost all over the underground battlefield.

Because although he was the number one demon king in the underground battlefield at the beginning, after all, there were countless great demon kings, and he couldn't be too strong, so as not to let other great demon kings join forces.

Therefore, he will not be too authoritarian in many things, and he will do it himself.

It's different now, he has achieved a generation of Demon Emperors, and he is also the best among the Demon Emperors, and he has the power to suppress the entire underground battlefield, so he naturally doesn't need to go in person at this time.

Because of the appearance of Emperor Ling Tian, the entire underground battlefield was busy.

Hundreds of millions of demons have been activated.

Along with those demon kings, great demon kings, and even demon brakes, they all moved.

In the underground battlefield, hundreds of demon generals, and even thirteen demon commanders, all came to Shatian Peak.

They took the initiative to come to surrender, and if they didn't come at this time, then there would be no chance in the future.

Ling Tianzhao accepted it all, in fact, this is also what Chen Daoqing meant, if he ruled all the hell demons in the entire underground battlefield, it would be a huge underground kingdom!

No less than the second Demon Realm!

Ling Tian longed for the Demon Realm the most, if he couldn't enter it in this life, he would regard the underground battlefield as the second Demon Realm.

For three days in a row, countless exotic flowers and plants in the underground battlefield were sent to the top of the Sky Covering Peak.

Because the demons didn't know the Nine-Leaf Demon Soul Grass at all, they collected some strange plants when they saw them and sent them.

Chen Daoqing and others have been carefully identifying, countless rare treasures, and they have gained a lot.

A lot of precious materials have been found, and Chen Daoqing has accepted them all, but it's a pity that the nine-leaf demon soul grass is missing.

"It seems that there is only one trip to the abyss. Chen Daoqing sighed.

Ling Tian frowned, in fact, he still hoped to be able to find the Nine-Leaf Demon Soul Grass beyond the underground abyss.

The place in the abyss is too strange, and he still has lingering feelings about this place after experiencing it and never returning.

"Actually, there's no need to worry too much, since a Demon Abyss Elder can appear here, there must be a special passage in it. Chen Daoqing said slowly.

Everyone nodded, in fact, they were all eager to try, hoping to enter the abyss to see what the most mysterious place in this underground battlefield was like.

"Maybe ......," Chen Daoqing wanted to say but stopped.

At the beginning, he had heard the Worm King say that the dungeon guarded by the Immortal Gate was the vein of the Heavenly Demon Old Man, and the underground battlefield of Hades Mountain was the vein of the Heavenly Demon Holy Monarch.

Both places seem to have a passage, a passage to the Demon Realm.

If the underground abyss can really connect to the Demon Realm, then the seal inside must have been loosened.

Otherwise, there was an underground abyss from which there was no return, why would there be an elder of the Demon Abyss?

In fact, Chen Daoqing is more related to the Heavenly Demon Holy Monarch's natal magic weapon, the Heavenly Demon Order Banner.

Now Chen Daoqing has collected eighty-three Heavenly Demon Order Flags, if he can collect one hundred and eight Heavenly Demon Order Flags, with Chen Daoqing's current strength, it will be enough to kill the immortal master.

How powerful a complete set of Heavenly Demon Order Banners is!

If you really have one hundred and eight Heavenly Demon Order Banners, it means that you have an immortal weapon that surpasses the level of the Sealed Cloud Sword, and how huge the power in it is.

"Okay, since that's the case, let's go down and have a look!" Ling Tian said slowly.

"Just to see what kind of place this underground abyss is!" Mu Langjun said with a smile.

Mu Langjun, who was originally sluggish, also seemed to have become active, except for the fact that the blood was always cold, everyone else was very harmonious.

"However, Ling Tian shouldn't go!" Xue Li suddenly spoke.

Everyone was stunned, and then Chen Daoqing nodded, understanding the meaning of Xueli.

"What do you mean!?" Ling Tian's tone was cold.

"There needs to be someone left here, and there's no one better suited than you. Chen Daoqing helped explain.

Ling Tian frowned, Chen Daoqing explained clearly enough, of course he understood, but he was still a little disgusted by Xueli, after all, he brought it up.

"That's the best arrangement. Mu Langjun nodded.

"Good!" Ling Tian nodded.

After everyone discussed, Ling Tian immediately led the group towards the direction of the underground abyss.

At this time, the Hell Demon Clan, who received the order, was surrounded by no less than hundreds of millions of demons in the underground abyss.

However, the howling wind continued to rise from the abyss underground, and no demon dared to approach it.

The moment they arrived, it was bustling and there was no edge in sight.

"I will live here for the time being, waiting for you to return!" Ling Tian said slowly.

This time, Chen Daoqing's will to go down was very strong, and no one could stop him at this time.

"The environment seems to have become much gentler. Ling Tian said slowly.

"Huh?" Mu Langjun frowned.

There are still more than ten miles away from the abyss underground, and the demons dare not approach.

Because the cold wind here is very strong, the demons will be swept into it or blown away by these strong winds if they get closer.

The wind here can blow a demon into powder!

"At that time, it was difficult for a demon to dare to enter within a radius of a hundred miles, and now it has retreated to more than ten miles, which shows that its strength has weakened. Ling Tian said slowly.

Chen Daoqing nodded, this is enough to show that he has retreated more than ten times!

However, the winds did not affect them at all.

The lowest level of the bloody realm are all the peak masters of the Yuan Infant Realm, and they don't care about these winds at all.

"In that case, you stabilize the overall situation outside, let's go in and take a look!" Chen Daoqing said solemnly.

Ling Tian nodded, in the entire underground battlefield, there were no other masters, Ling Tian was enough to stabilize the situation.

Outside the underground battlefield, there are immortals such as the Worm King, so there is no need to worry.

Chen Daoqing, along with Mu Langjun and Xueli, rushed towards the abyss underground.

Before leaving, he still left Ling Tian with a Divine Power Realm-level Hanhai borer.

This is also convenient in case of any accidents, there is a special induction between the Hanhai borer family.

Chen Daoqing and the others resolutely entered the abyss.

This is a bottomless underground abyss, it seems that there is no passage at all, Chen Daoqing looked down at the abyss, and the bursts of demonic energy in it were wanton, and it was extremely rich.

"It seems that this is the source of the demonic energy of the entire underground battlefield. Chen Daoqing said solemnly.

The underground battlefield has tens of billions of demons, and they need to absorb demonic energy to survive, and the winds here are actually endless demonic energy.

Now that I think about it, if the wind really weakens, it means that the entire underground battlefield is slowly withering, and without the replenishment of demonic energy, can these demons continue to survive?

This was also Ling Tian's question after coming to the underground battlefield.

According to the speed of demon reproduction, after more than 20 years of life and reproduction, the number of demons should be around 150 billion, but now this number simply no longer exists.

And even decreasing.

Chen Daoqing seemed to understand.

Because there is less demonic energy overflowing here, the demons in the entire underground battlefield cannot survive, and the final result is that they kill each other, the speed of life and reproduction slows down, and even no new demons appear.

If this continues for a long time, I'm afraid that the demons of the entire underground battlefield will no longer exist.

However, the reason for this is why the demonic energy here has decreased?

There must be something wrong in the abyss.

Chen Daoqing wants to establish an underground kingdom in Hades Mountain, and he must not allow the demonic energy to weaken, otherwise the demons will all die, so what is the use of him wanting this empty underground battlefield?

"Let's go, let's go down and have a look!" Chen Daoqing smiled slightly.

These people are all masters of art and bold, and they suddenly leapt into the abyss of the earth.

In an instant, endless demonic energy began to fill their bodies, and although the wind was strong, their bodies were stronger and would not be afraid of these small winds.

They are descending little by little, it is pitch black here, if it is an ordinary person, it must be out of sight, but even Chen Daoqing and others, their visibility is only a few tens of meters.

This vertical descent is also extremely costly for them.

Fortunately, Chen Daoqing provided endless pills, otherwise Mu Langjun and Xueli would not have lasted long.

For the World Tree, Chen Daoqing still has something to hide, although the Jiuding Qiankun Diagram is full of endless aura, and Xueli and Mu Langjun have also felt the true meaning of it, but after all, they still don't know what the aura is generated, and even think that this is the aura that comes with the Jiuding Qiankun Diagram.

"Be careful!"

Suddenly, Chen Daoqing felt a huge crisis, and before his words fell, he had already made a move.

He didn't make a sound just now, but he was actually the first person to find out about the sneak attack.

Bang! Bang!

Blood Li slashed out three swords in a row, these three swords carried endless murderous aura, although he lost the sword of blood killing, but the sword that could make Blood Li hold in his hand was itself condensed with endless bloody aura.

The bloody vigilance defused the opponent's attack, and at the same time, Chen Daoqing and Mu Langjun also shot at the same time.

The joint attack of the three masters, as the leader of the younger generation in Kyushu, even if those old guys from the Hongmeng Realm appear, they may not be able to bargain for anything.

Boom! Boom!

The other party's black shadow was immediately restrained, and the three masters bombarded fiercely.

It's just a Demon Emperor, and it's an ordinary Demon Emperor.

A Demon Emperor of this level could not be compared to Ling Tian at all, and it could only be regarded as one-tenth of Ling Tian.
