Xuan Yi landed steadily and sized up the huge palace in front of him.

Although it didn't look very big from the top, when he was actually standing in front of it,.

Xuan Yi still experienced his own insignificance.

Just this exposed corner of the underground palace stretched nearly a thousand miles.

Not to mention the size of the palace hidden under the ground.

To enter the underground palace, one had to pass through the huge city wall in front of it that was tens of thousands of feet tall.

The Dao aura flowed continuously on the wall, even after millions of years.

It was still extremely sturdy.

However, the ten great Sects still had some ability.

It was not an easy thing to enter through this city wall.

At the bottom of the city wall, there was a hole.

It could allow three to five people to pass through.

It seemed that the ten great Sects had all entered.

Xuan Yi did not stop at all. He stepped forward.

After entering, the murderous aura surged over. Xuan Yi used his own circulating spiritual essence to defend himself.

Perhaps due to a long period of accumulation, the murderous aura inside had far exceeded Xuan Yi's imagination.

However, Xuan Yi was still able to hold on.

Not long after he entered, Xuan Yi ran into a group of people from the Fire Cloud Sect.

However, Xuan Yi had the jade talisman on him, so after they greeted each other, they left.

There wasn't the slightest doubt.

After the time it took for an incense stick to burn (approximately an hour), Xuan Yi stepped onto the city wall.

He came to an extremely wide place.

Just by looking with the naked eye, there were over a thousand cultivators wandering around.

Some were hunting the lone fierce beasts to earn source films.

Some were hunting other cultivators.

Xuan Yi jumped down and easily blended in. No one doubted Xuan Yi's identity.

This was the stronghold of several Sects.

There were many camps around. Xuan Yi walked amongst them and observed the situation.

He walked all the way to the Fire Cloud Sect's encampment and roughly understood the source film.

The disciples of the ten great Sects killed fierce beasts and collected the source film.

They could exchange it for corresponding rewards within their Sects.

He also roughly understood the source film.

The source film carried the power of the laws of heaven and earth.

This was very important for those who were in the Heavenly King Realm to make further breakthroughs.

It could speed up their cultivation speed and help them.

Of course, there was a difference in the quality of the source film.

For example, the source film obtained from killing a Heavenly King Realm fierce beast was obviously different from that obtained from killing a Saint Realm fierce beast.

Whether in quality or in size.

The higher the realm of the fierce beast, the more powerful the source film it had.

The source film obtained from killing a Heavenly King Realm Beast would be very useful even for a Heavenly King Realm cultivator.

Any higher than that, and it would be much less useful.

For an Emperor Realm cultivator, the value of a Heavenly King Realm beast was obviously not that great anymore.

Xuan Yi roughly estimated how many source films he would need to break through to the Heavenly King Realm.

He had built hundreds of nodes at the same time, but due to various reasons, only a few of them had been completed as prototypes.

The others were not even considered to be prototypes.

Only the first node was considered to be qualified.

These used up about half the size of Xuan Yi.

If converted to weight, it was estimated to be about 40 to 50 catties.

Calculated this way, if Xuan Yi wanted to complete these hundreds of nodes,.

He would need at least a thousand catties of source films.

It was definitely impossible for Xuan Yi to collect such a huge amount by himself.

It would take too long, and Xuan Yi didn't have that much time to waste.

He had to speed up the pace.

If that was the case, Xuan Yi had a way.

Right in front of him was his enemy's Sect, the Fire Cloud Sect.

The Fire Cloud Sect had been in the archaic battlefield for a very long time, and they had so many people.

Presumably, the number of source films that they had collected must be extremely terrifying.

He acted without delay.

In any case, he had already killed the their disciples anyway.

It wouldn't matter if he snatched some things.

Now that things had come to this point, there was no possibility of redemption.

Moreover, Xuan Yi didn't regret it, and he wouldn't choose redemption.

"Holy Son, Holy Daughter, there's a new group of fierce beasts ahead. The Sect leader wants me to report it to you."

"Please bring 300 disciples with you. Be careful."

The disciples around Xuan Yi looked terrified. They quickly lowered their heads and left.

They said as they walked.

"Let's go, let's go. We don't want to be caught by them. Otherwise, we won't be able to come back."

"That's right. Those elders gave them the life-saving techniques, but leave us to die. No, no, let's go."

It wasn't just the people around Xuan Yi. The people from other Sects in other areas were the same.

Obviously, they knew what the other disciples were like.

Xuan Yi hid in the crowd to avoid revealing any flaws.

He carefully observed the so-called Holy Son and Holy Maiden.

The Holy Son was tall and handsome while the Holy Maiden was small and cute. It was said that they were brother and sister.

Both of them were favored by the Heavens. The Holy Son was called Huo Hua. As for the Holy Maiden, she was called Huo Rong'er.

Both of them were at the peak of the Sage Realm.

It was said that the siblings had a unique secret technique that they could use together.

Their minds were one and their power was greatly increased. They had once killed an existence who was at the initial stage of the Heavenly King Realm.

Xuan Yi silently recorded their information in his heart.

They would eventually be used.

Xuan Yi walked around, collecting all kinds of small news, especially those about the Fire Cloud Sect.

After all, it was a Sect with a Heavenly King Realm cultivator overseeing it. He could not be careless.

Although Xuan Yi had a trump card like Bing Yu,.

But this ancient battlefield was strange and unpredictable, and there was also this so-called underground palace here.

It was even more dangerous. It was best to be careful.

No matter how strong Bing Yu was, she was still a Heavenly King Realm cultivator.

Even Emperor realm cultivators had been to this primordial battlefield before.

Around four hours later, Huo Hua and Huo Rong'er returned with the disciples.

However, it was clear that they had suffered heavy losses.

Huo Hua was slightly more seriously injured. As for the three hundred disciples, they suffered even more heavy losses.

Their lost was nearly 40% .

The death rate was too high.

Not long after they returned, another piece of news was sent out.

A new palace had been discovered at the front line.

They were preparing to gather people and explore it.

It was said that the restriction on the palace was well-preserved. There would probably be many good things.

Even better, after the discussion of the ten great Sects.

In the afternoon, they would send their disciples and elders to explore the palace.

At that time, only Huo Hua and Huo Rong'er would be left to oversee the Fire Cloud Sect.

The other disciples, in the eyes of Xuan Yi, were of unconcern.

Xuan Yi maintained his patience and continued to wait.

He could not be too impatient, or else he would easily be exposed.

At night, Huo Hua was concentrating on his cultivation to heal his injuries today.

Huo Rong'er was very bored at the side, teasing the spirit beast she brought.

Suddenly, the spirit beast hid. Huo Rong'er was stunned for a moment, then immediately summoned her long sword.

The Fire Cloud Sect's camp was suddenly set on fire, and a few disciples were injured.

Xuan Yi's figure appeared in front of the back of the camp.
