After dinner, the Sect Master Tianyan took Mu Tian and the others to say goodbye.

Half a day later, I returned to the forbidden cave in the back mountain of Tianyanzong.

"Two disciples, you are practicing at home. You may have to socialize outside during this period of time. This time you have given the teacher a face, hahaha..."

As soon as I returned to the Forbidden Land Cave, before my butt was hot, the Sect Master Tianyan was about to go out.

"Master, how long do you have to go out?"

Mu Tian asked.

"This is hard to say. It may be half a year, a year, or a longer time."

The Sect Master Tianyan stroked his beard and replied.

"Oh, can we go down the mountain and play in the city? It's boring to stay here all the time, so it's impossible to keep practicing."

"You can do whatever you want, by the way, you can go to the Kung Fu Hall to choose whatever you want without any restrictions."

"Okay, that's all right, Master, be careful."

"Hahaha... Don't worry, there are only a handful of people who dare to move as their master in the world, let alone not many people will be your master's opponents."

"Yeah, the master walked slowly, let's go back to the room to make a sleep."

"Go, my teacher is gone. Remember to bring some people when you go out to the city. You can transfer the elders in the gate at will. My teacher has already said hello."

"No need. With our strength, it's not a demigod who can't hurt us at all."

"Okay, then the teacher is gone, you guys are careful."

After saying that.

The body of the Sect Master Tianyan flashed and disappeared into the cave instantly.

"Brother, our chance is here, hehe!"

As soon as the leader of Tianyan left, Mu Tian touched his chin and said with a sinister smile.

“What opportunity?”

The gang leader didn't understand what Mu Tian meant.

"You forgot to study the secrets of Tianyanzong's back mountain."

Mu Tian gave the gang leader a blank look and replied.

"You really want to study Tianyan's back mountain?"

"It's a must. There are so many barriers in the back mountain of Tianyan, there must be some secrets."

"Okay, since you have decided, let's study it."

"Yeah, let's have a nap and it will start tomorrow."

Meimei had a nap. The next afternoon, Mu Tian and the others went to the city to have a meal, and then prepared some food!

After returning, the sky gradually darkened, and I studied the mountain behind Tianyan, which began at this moment.

"Old rule, let the four formation emperors come out together."

At the beginning, Mu Tian released the Formation Emperor and began to break the Formation.

This time, Mu Tian did not only break through one passage, but directly broke the formation. Wherever he went, the formation barrier was directly broken.

Without breaking the barrier, there is no way to study the secrets of Tianyan’s back mountain.

A month passed in a blink of an eye, and with the concerted efforts of Mu Tian and the six people, they broke through the barrier of hundreds of meters.

The range of hundreds of meters looks very large, but compared to the entire Tianyan Houshan, it can only be regarded as the tip of the iceberg.

"No, this speed is far from enough, we must speed up."

While resting, Mu Tian said.

"We have tried our best, and I'm afraid we can't get any faster."

Li Ge said.

"I know the four seniors have tried their best, but the gang leader can be faster."

Mu Tian smiled and looked at the leader of the gang.

"I? You mean I didn't do my best?"

The gang leader pointed at himself and questioned Mu Tian.

"It's not that the leader of the gang didn't do his best, but that you can do your best."

"I understand what you mean, okay, I'll do my best."

After saying that.

The gang leader immediately used the power of the way of heaven to break the formation with the power of the way of heaven.

"start!"

Seeing that the gang leader had begun to use the power of the Heavenly Dao, Mu Tian immediately joined and resolved those barriers as quickly as possible.

Time passed minute by minute, and another month passed in a blink of an eye.

The effect in this month is significantly greater than the previous month, at least several times.

Two months later, Mu Tian and others broke many barrier formations, but they had not seen any abnormalities.

So Mu Tian and others continued to work hard to uncover the secret of Tianyan’s back mountain as quickly as possible.

Mu Tian must keep the time within half a year, because the leader of Tianyan said he would come back as soon as half a year.

Once he comes back, the consequences will be unimaginable.

If the barrier is cracked, it is equivalent to a complete break with the Sect Master Tianyan. He will never allow anyone to move the forbidden land of Tianyan.

Time is like flowing water, and more than two months have passed in a blink of an eye. In addition, in the previous two months, Mu Tian and others have been working for four consecutive months.

At this time, most of the barriers in Tianyan Back Mountain had disappeared.

“Some discoveries!”

Suddenly, Mu Tian found something strange under a rockery.

"There is a hole!"

Soon, the gang leader also discovered that it was a hole.

"It seems that the secret is under this rockery!"

Li Ge stroked his beard and said.

"It's an underground palace entrance."

When I climbed over the rockery, a cave entrance appeared, which was similar to the previous cave entrance, and there were also steps, which must be the entrance to the underground palace.

"Let's go, let's go and have a look first."

"After a moment, I have to put away the four seniors Li Ge's first. We don't know what the following is. We can't let the four seniors take risks."

"We're fine, let's go together, there's still some advice."

"No, we can protect ourselves, but we cannot guarantee the safety of the four seniors."

After saying that.

Mu Tian stopped talking nonsense, waved his hand and took the four seniors into the seven-color Xuantian Ring.

"Let's go down."

After putting away the four brothers Li Ge, Mu Tian said to the gang leader.

The stairs are not deep, and they are only about ten meters away.

"boom!"

When Mu Tian and the others went down to the bottom, a roar immediately came, and the dark underground lighted up.

A winding and twisting cave appeared in front of him, and the lampstands were lit on both sides of the cave.

"Let's go, be careful, I smell a dangerous smell."

Mu Tian sensed it for a moment, and then walked carefully towards the cave.

I thought the cave would be very long, but after walking a few hundred meters, I saw a brightly lit hall.

Standing at the corner, you can see everything in the hall clearly, with golden light shining everywhere, and even the ground is inlaid with gold objects, which is extremely luxurious.

"Someone..."

The gang leader said softly.

"I sensed it too, the breath is very strong..."

Mu Tian nodded and replied softly.

"Then what are we doing now? Do we still need to go in?"
To be continued...
