This palace is very large. It was originally built by the elders of the Sky-Swallowing Beast to protect the inheritance place behind the forbidden area.

After walking around once and listening to Zhongdi's explanation of the formation's layout and arrangement, Gao Han returned to the treasure house.

He did not refine the materials immediately, but took out a book.

This is half of a book on weapon refining that they obtained from Wanxiandao.

He had read all the methods of refining immortal weapons in Wuming Peak a long time ago, but he was missing the other half, so he only knew one part of it and not the other.

Zhongdi took out several magic weapons and placed them in some corners of the palace. This was the condition for activation.

If you rely on the energy of the formation itself, you will not be able to trap the demons and monsters. Using magic weapons can extend the time and consolidate the formation.

On the other side, Zhongli Tingzhou and Xuan Xiao finally threw the immortal weapon they had moved over under the altar.

The powerful immortal weapon that once dominated the ancient times, under the decomposition of the formation, melted into balls of liquid, and diluted more energy, which was integrated into the restriction and completely disappeared between heaven and earth.

“In fact, the Demon God collected so many weapons from powerful men back then so that those powerful men who died in the war would have something left in the world so that they would not be forgotten forever.” Xuan Xiao said with emotion as he watched this scene.

Zhongli Tingzhou glanced at him and said, "It's obviously your collecting addiction that's causing it."

Xuan Xiao was choked. Please don't be so straightforward.

Bai He also wanted to clear the name of the demon god, but after thinking about it, he shut up.

Zhongli Tingzhou looked at their slightly puffy faces, and suddenly he felt a sense of evil humor. "You might as well imagine that after the great battle, your demon gods were obviously also seriously injured, but they squatted on the battlefield, sticking their butts out to pick up the immortal weapons of the strong. It must be very interesting, right?"

The two people's minds involuntarily followed his words, and when they couldn't help but imagine that scene, the great and sacred image of the demon god in their hearts collapsed in an instant.

"Stop talking, the Demon God can't possibly do that!" Xuan Xiao took a deep breath.

Bai He blushed from holding back, "That's right, even if the great demon god really has a collecting habit, he couldn't have done it himself. Maybe, maybe it was done by another elder of the Sky-Swallowing Beast."

Xuan Xiao quickly agreed, "Bai He is right, that's it."

Zhongli Tingzhou shrugged, "I'm just guessing. Believe it or not, it may really be like what you said, that other Sky Devouring Beasts collected them."

The two did not feel happy at all. Now, whenever they thought of the Demon God, the scene of the Demon God picking up the artifact would involuntarily emerge in their minds, restoring their image of the great and selfless Demon God!

After the three of them came back, Gao Han noticed that Xuan Xiao and Bai He looked depressed, and cast a questioning look at Zhongli Tingzhou.

Zhongli Tingzhou shrugged, but Gao Han didn't believe it.

Zhongdi asked them, but the two refused to say what had happened. They had been tortured, and they couldn't let Zhongdi be tortured as well.

"What are you looking at?" Xuan Xiao suddenly asked at this time.

Gao Han was about to put the book away when he heard this and said, "It's half a book about refining equipment."

"Half a book?" Xuan Xiao was stunned for a moment.

"What's wrong?" Gao Han's eyes met his.

Xuan Xiao came back to his senses, "I feel like it looks familiar, as if I've seen it before. Wait a minute, I'll look for it."

It was Gao Han's turn to be stunned. He watched him dive into the ball of light.

"When Xuan Xiao gets bullied outside, he will run to the treasury to find something, and then go out to take revenge. Among us, he is the only one who has searched the entire treasury. No one is more familiar with it than him." Chongdi's voice sounded beside him.

After a while, Xuan Xiao came over with a box, "Take a look and see if the contents are the same as yours."

Gao Han immediately opened the box, and sure enough, there was half a book inside, and it happened to be the other half of the book that was torn off in his hand.

"The Sky-Swallowing Beast Tribe even collects books on weapon refining?"

"This was not picked up by the Demon God." Xuan Xiao refuted immediately, but when he noticed Zhongdi's suspicious gaze, he realized that he had overreacted and quickly shut up.

Chongdi put this doubt aside for the time being and explained, "According to the records of our clan, this half of the weapon refining book should have been won by the demon god in a bet. The Hundred Refining Immortal Lord lost and was unhappy, so he tore up half of the book and gave it to the demon god of our clan."

"Bai Lian Immortal?" This was the first time Gao Han heard this name.

"Well, it is said that Bailian Xianjun is the number one weapon refiner in the fairy world. He often bets with the demon god and loses a lot of fairy weapons."

No wonder he always felt that there were too many magic weapons in the treasury. It turned out that many of them were won from bets.

"These two are so sentimental, what did they bet on?" Zhongli Tingzhou asked excitedly. He also liked to bet, but unfortunately no one wanted to play with him.

“It’s like a guessing game.”

"for example?"

Zhongdi suddenly coughed and said, "I forgot. There is no detailed record of it."

Zhongli Tingzhou sneered, "I don't believe that you, the demon god, who loves to show off, would not have written it down."

"How do you know?" Bai He asked, then realized that he had let the cat out of the bag, so he covered his mouth again.

"Stop messing around, go and prepare. How long can the ban last?" Gao Han brought the topic back to the weird one.

The three gold-eating beasts immediately looked at him gratefully. Xuan Xiao said, "We have thrown so many immortal weapons. If everything goes well, we should be able to hold out for a day."

"Okay, I'll start now. You guys go out and don't disturb me unless necessary." Gao Han nodded and drove them out.

Zhongli Tingzhou was the last one to walk out. He looked at the three gold-eating beasts and said, "You..."

"I have to guard the altar and observe the situation of the ban at any time." Xuan Xiao said and left immediately.

"Wait for me, I'm going too." Before Bai He finished speaking, people had already chased out.

Zhongli Tingzhou looked at the remaining important land and said with a smile: "Let's go and set up the formation for the palace."

I followed him with a heavy sense of uneasiness in my heart, feeling that something was about to get out of my control.

A quarter of an hour later, Zhongdi finally understood why Xuanxiao and Baihe looked so hopeless when they came back, and he felt the same way now.

After the door of the treasure house was closed, Gao Han sat on the ground alone and used his spiritual sense to scan the contents of this half of the weapon refining book into his mind. After reading it several times, he had a general idea of ​​the method of refining immortal weapons.

The method of refining immortal artifacts is actually not particularly different from that in Lingtian Continent. If there is any difference, it is probably the gift from heaven.

However, since the disappearance of the fairyland, the gift from heaven has disappeared, so fake fairy weapons appeared.

The fairyland still does not exist today, so if you want to refine a real fairy weapon, you still cannot do it in the Lingtian Continent unless you find something that can be exchanged.

This kind of thing was vaguely mentioned in the book, a kind of stone from outer space, but it seemed that even this Immortal Lord Bailian had never seen it.

Only now did Gao Han realize how precious the immortal weapons were. If he used them for self-protection, each one would be one less.

Gao Han took out all the materials and placed them in front of himself. He first put aside the phoenix feathers and refined the other materials.

I don't know if it was his illusion, but his speed of refining materials was not slow originally. However, after burning them with the Sun's Fire for half an hour, there was not much change on the surface of the materials.

“Is it because my flame level is not high enough, and these materials are from the fairy world?”

He tried to refine the materials from Lingtian Continent and achieved results after half an hour.

“Even the Sun Lihuo doesn’t work, could it be…” Gao Han’s gaze fell on the Phoenix Feather beside him.

He hadn't wanted to try this, but now it seemed there was no way.

Before refining the phoenix feather, Gao Han took out the jade slip and told Zhongli Tingzhou about the situation here. If he couldn't repair the Yayoi Ring, he could only try Zhongdi's method.

"It's best not to let him try to refine the Phoenix True Fire easily. It can really kill people." After listening to what he said, Zhongdi warned him solemnly.

If it can be repaired, that would be the best. If not, he doesn't want to see his benefactor get into trouble. If the young master knew about it, he would be very sad.

"Did you hear me? Don't try it rashly, or I won't let you go even if I become a ghost." Zhongli Tingzhou said in a sinister voice.

"I know. I know my limits." Gao Han responded calmly.

Chongdi showed surprise, and then remained silent. This human cultivator was very strange, very different from the humans he knew, and no one could understand what he said.

Why did Gao Han try, but the other party refused to let him go even though he was a ghost? He totally couldn't understand the logic behind this.

"You do it yourself. I'll go outside the treasury to guard Gao Han." Zhongli Tingzhou said and left decisively without asking for his opinion.

Chongdi had no objection. Before the demons and monsters outside attacked, the forbidden area was safe. Moreover, he could breathe a sigh of relief after he left. He didn't have to listen to his twisted logic anymore. He now knew why Xuan Xiao and Bai He ran so fast.

Outside the forbidden area, a large amount of blood and energy rose into the sky, and another two hundred demons committed suicide. Their blood, energy, and resentment all turned into the body of the demon-eyed beast.

The body of the Demon Eye Beast has gradually grown from half a meter in size at the beginning to ten meters in width.

At this time, it was still continuously absorbing the forbidden energy, and the energy continued to surge and gather towards the Demon Eye Beast.

Finally, the restriction weakened at a speed visible to the naked eye, and the vibrations in space became more and more obvious.

Everyone kept a close eye on the ban, including the monsters several thousand meters away.

After a long time, no new energy came out of the restriction.

Everyone breathed a sigh of relief.

"Finally, the gold-eating beast inside is finally helpless!"

They stayed here for a full five and a half days. Every time the restriction was about to be drained of energy by the Demon Eye Beast, a huge amount of energy would surge out the next moment, restoring the restriction to its peak state. This happened countless times, and they couldn't even remember.

They were angry at first, then furious, and later on, no amount of anger could describe their mood at the time.

Until now, they finally saw a glimmer of hope.

At this moment, the sluggish restriction suddenly made a humming sound, and the vibrating spatial patterns seemed to be smoothed out at once, and it became quiet again in an instant.

Demons and monsters: "..."
