I will return you 10,000 times my money. I am the strongest furnace in the Demon Sect.

Good fellow, the little cow is flirting.

Who can stand this?

Must be executed on the spot!

This disturbance delayed for more than an hour.

After regrouping, Zhao Mu continued hunting.

Half a day later.

The terrain of the canyon suddenly became flat, and it seemed to be at the end.

After crossing the entire canyon, the scene in front of him surprised Zhao Mu a little.

There is an ancient stone city here.

But the city-state has been abandoned for an unknown period of time. Even the most solid rocks have left obvious traces under the baptism of time.

"Strange, judging from the degree of weathering of the stone, this ancient city has been abandoned for at least 100,000 years. However, this Warcraft Secret Realm has only been built for 8,000 years. How could this ancient city appear in the secret realm?" Niu Yulan also found something strange.

Zhao Mu said: "Is it possible that the powerful and powerful who built this Warcraft Secret Realm cut a piece of land from the outside world and put it into the secret realm?"

"That's a bit possible."

Niu Yulan nodded.

The two walked straight into the ancient stone city. There were no magic beasts here, but they unexpectedly encountered many disciples of the Demon Sect.

Apparently, they were also attracted by this ancient stone city.

"It's really strange. I have participated in several hunting days and have been to this place several times. I have never seen such an ancient city ruins here before." A chubby demon cultivator slapped his forehead and looked puzzled.

A horse-faced monk also muttered: "Although this is the first time I have entered the secret realm so deeply, I have participated in hundreds of hunting days and have never heard of any ruins here. Could it be that this suddenly appeared ruins was built by magic beasts?"

"Look carefully, although the traces of weathering look very natural, if you observe carefully, you will still find traces of artificial polishing."

A human cultivator squatted down and stared at a square stone door beam and said.

His words aroused the curiosity of everyone, and they all went over to check.

Zhao Mu also felt a little incredible, and went forward with Niu Yulan to check the situation.

When everyone found Zhao Mu, they immediately showed a vigilant expression.

Only the human cultivator saw Zhao Mu and immediately showed joy: "Brother Zhao, I have heard of you for a long time. You are also curious about the ruins of this stone city. Sorry, you should have joined the Demon Sect not long ago. This is your first time to participate in the hunting day. I have been in the Demon Sect for more than 500 years and have experienced more than 400 hunting days. I can guarantee that this stone city has definitely appeared recently and has been built for no more than a year."

This guy is quite talkative. He did not give Zhao Mu a chance to speak at all. He talked a lot.

"By the way!"

The human cultivator suddenly clapped his hands and said: "Brother Zhao, as a human genius, you are strong. Maybe you can break the blocked stone door."

"Blocked stone door? Where is it?" Zhao Mu asked curiously.

The man was about to speak, but suddenly glanced at the demon cultivators around him, lowered his voice and said to Zhao Mu: "Brother Zhao, let's talk somewhere else."

Zhao Mu nodded.

It seems that this guy has some exclusive information.

The demons realized something was wrong, but after some hesitation and struggle, they did not dare to follow.

Zhao Mu has been famous recently. He is a big shot of the Shengyuan Demon Sect. Even the Queen Qingyun was alarmed by him. It is unwise to be his enemy now. It is better to take a step back and keep things peaceful.

After a while, Zhao Mu and the human cultivator came to a nearby ruin.

"Hello, Senior Brother Zhao. My name is Xu Yang. I am an inner disciple of the Formation Valley. I have met you before. I was impressed by your youthful demeanor."

Although Xu Yang claimed to have been a disciple for 500 years, his cultivation was not high. He was only at the eighth level of the Jindan realm. He looked a little vicissitudes of life. Although he did not show any old age, his skin was dark and rough. It seemed that he had been walking outside for many years and had been exposed to the wind and sun.

"Since we are from the same sect, there is no need to beat around the bush. What is the matter with the blocked stone door you just mentioned?" Zhao Mu said directly.

Xu Yang was about to speak, but suddenly he glanced at Niu Yulan beside Zhao Mu, his eyes alert.

"You can say whatever you want, she is my confidant." Zhao Mu grabbed Niu Yulan's hand and interlocked his fingers with hers.

Niu Yulan's heart warmed up, her eyes were full of Zhao Mu, and she completely ignored Xu Yang's existence.

Seeing this, Xu Yang no longer hesitated and said, "In fact, I came to this stone city ruins yesterday. At first, I also suspected that this stone city existed before the secret realm was built, but then I found many traces of artificial polishing, so I guessed that this ancient city was a newly built antique work, but I couldn't produce any key evidence, but last night, I dug three feet into the ground and found a stone door buried underground. The stone door was extremely heavy and blocked by the power of the formation. Although I cracked the formation on the stone door, it was too heavy and I couldn't push it open with my strength..."

At this point, Zhao Mu probably knew what Xu Yang meant.

"Lead the way. I'll try to see if I can break the stone door."

"Brother Zhao, please!"

Xu Yang was overjoyed. With a human genius like Zhao Mu helping him, it shouldn't be difficult to break the stone door.

He was full of curiosity about the truth hidden behind the stone door.

As the three of them were moving, Zhao Mu keenly noticed that the demons were following far behind.

Zhao Mu's eyes turned cold, and he struck out with a palm in the direction of several demon cultivators. Suddenly, fire shot into the sky. Wherever the palm wind passed, the stone house collapsed, the earth cracked, and billowing heat waves continued to flow, scaring the demon cultivators into panic. Run away.

After driving away the Xiaoxiao people, Zhao Mu and the others continued to move forward, and soon Xu Yang brought them to a relatively well-preserved stone house.

In the center of the stone house, there is a staircase leading to the underground, which spirals downwards and is as deep as four or five floors.

At the bottom of the steps is the stone door Xu Yang mentioned.

This stone gate was plain and simple, with nothing special about it, but Zhao Mu could see the problem at a glance.

The materials used to build the stone door looked very familiar to Zhao Mu.

It is the same type as the large piece of ore he dug in the Sea of ​​Corruption.

This kind of ore is extremely dense, heavy and solid, and it is difficult for an eighth-grade flying sword to leave any obvious traces.

No wonder Xu Yang couldn't open the stone door made of this kind of ore.

"It's just a door. Why can't it be opened? Let me try."

Niu Yulan volunteered.

She was born into the Demonic Cow Clan, and her strength was not ordinary. Zhao Mu had realized this when he explored the cave before.

It wouldn't hurt to let her try.

I saw Niu Yulan rolling up her sleeves, revealing two white and tender little arms.

The seemingly weak arm burst out with tremendous power the moment Niu Yulan exerted her strength.

Snap!

The stone door hadn't been pushed open yet, but the ground beneath her feet had cracked into even cracks, and her legs sank deeply.

Niu Yulan opened her eyes wide and was shocked.

"It's such a hard stone. Junior brother, I'm afraid it won't work anymore, so I'll leave it to you."

Niu Yulan really gave in.

In fact, she still has some energy left. If she explodes with all her strength, it won't be a problem to increase her strength by another 30 to 40%.

But in front of the one she loves, she is unwilling to reveal her too brutal side.

In front of Junior Brother Zhao, I am still more suitable to be a weak and weak woman.
