"What a tall copper tower!"

Lin Feng was shrouded in divine thoughts, and his attention was all attracted.

"Lock Demon Tower!!

Lin Feng didn't know how tall such a towering bronze tower was in the sky.

However, under the shroud of divine thoughts, at the top of the first layer, I saw the three clear big characters of 'Lock Demon Tower'.

Below the big characters, there is a gate formed by a light curtain, and the Dao Yuan pattern is constantly flowing on the light curtain.

"Spatial Confinement Yuan Pattern ......"

In the previous life, Lin Feng's control of Yuan Wen was extremely high.

At just a glance, he could see the specific situation of these Yuan patterns.

All the Yuan patterns flowing on the door of the light curtain can actually be divided into eight different groups of Yuan patterns, which are independent of each other and complement each other, and finally form a powerful imprisoning force on the door of the light curtain.

"To be able to use the power and intention of the immortal yuan to carve such a complicated yuan pattern on the magic weapon, the owner of this lock demon tower has a good control over the yuan pattern. ”

Lin Feng retracted his thoughts and walked towards the Lock Demon Tower.

As the first immortal emperor of the Nine Heavens in the past, he knew very well the role of the Demon Lock Tower, most of which were used to seal the fierce beasts.

Lin Feng really wanted to know what kind of fierce beasts were imprisoned inside such a towering in the middle area of the Burial Immortal Battlefield. The most important thing is that he wants to control the Lock Demon Tower and let the fierce beasts inside be used for himself.

"Master Lin, did you find any treasure?"

Su Longbow and Ruth could clearly feel Lin Feng's strangeness.

In my eyes, I was full of anticipation.

"Let's go!"

Lin Feng nodded, and took the lead towards the Lock Demon Tower.

"Great, finally found the baby again!"

The two were thrilled and followed.

......

Just when Lin Feng and his party, three people and two beasts, rushed to the Lock Demon Tower.

A few kilometers away, a young powerhouse of his age, carrying a long knife on his back, looked at the bronze giant tower standing in front of Lin Feng, and cast a scorching gaze.

"That one, the bronze tower towering into the sky, is the lock demon tower recorded in the ancient books of the sect, right?"

Xuan Wuji's excited voice was filled with an irrepressible tremor.

This was the first time in his life that he had entered the Burial Immortal Battlefield, and he never thought that this Lock Demon Tower, which had not been found by the heirs of the entire Xuanyu Sect for thousands of years, appeared in his sight.

According to the ancestral records, in the lock demon tower, suppress the ten thousand fierce beasts, once the lock demon tower is refined, and the fierce beasts inside are controlled, they can become the supreme of heaven and earth, which is the so-called Kunxu immortal, and even the venerable in the immortal gate are not their opponents.

"When I get the Lock Demon Tower, the universe of heaven and earth will be my Xuan Wuji. ”

Xuan Wuji was excited, and at the fastest speed, he galloped towards the Lock Demon Tower.

......

Lin Feng's footsteps were very fast, and after a short period of effort, he took Ruth, the Su Longbow, as well as the Emotional Beast and the Vine Wood Beast, to the Lock Demon Tower.

"Lock Demon Tower. ”

Lin Feng came to the huge entrance and stopped, only to see that the passage leading to the inside of the giant tower was blocked by a huge light curtain.

Above the light curtain, there are three quaint characters written on the Lock Demon Tower.

"Boom!"

"Boom!"

On the door of the light curtain sealed with the Yuan pattern, between the fluctuations, the terrifying power fluctuations of the Dao continued to emerge.

That kind of fluctuation is like the huge mushroom cloud that explodes after the nuclear bomb is detonated, just a glance is enough to make people daunting.

"Roar!"

The Mood Beast and the Vine Wood Beast seem to be full of fear for the Light Curtain Gate.

They roared under their breath and involuntarily stepped back.

"Don't be afraid, these powers are only used to seal the monsters in the Demon Lock Tower, as long as you don't impact the light curtain, it's fine. ”

Lin Feng didn't know how long this Lock Demon Tower had existed, but as long as he could guarantee such a powerful sealing power, it was enough to prove that the former owner of the Lock Demon Tower had a good strength.

"Roar, roar, roar......"

The Mood Beast and the Vine Wood Beast continued to roar in a low voice for a few times before slowly calming down.

However, their gaze on the door of the light curtain was still full of fear, and even under the subconscious movements, their steps took a few steps back.

"Whoosh......"

Lin Feng summoned the Mixed Yuan Flying Sword, and the strength of his whole body exploded.

Even so, the finger tip was still just scratched out, a shallow opening.

After a drop of blood was thrown by Lin Feng towards the Lock Demon Tower, this shallow opening returned to normal. If it weren't for the incision, there were some shallow blood marks, and there was no abnormality at all.

This is the power of the Five Elements Immortal Body, once it reaches a certain realm, even if you want to harm yourself, it is an extremely difficult thing.

"Buzz!"

The blood flickered and melted directly into the door of the light curtain.

"Great!"

Lin Feng was overjoyed.

For the magic weapon that has had an owner, the biggest difficulty in refining it is to drive away the original owner's imprint in the magic weapon. Only in this way can it be truly refined.

But he never thought that such a lock demon tower, whose power seal was still so terrifying, would not have the imprint of the original owner on it.

In this way, it is easiest to refine it. As long as the blood is infused, it can be quickly refined with some powerful refining methods.

"Whoosh!"

In Lin Feng's previous life, he had mastered so many refining methods.

And each of them is a powerful method that can be ranked in the starry sky.

I chose one at random, the most suitable refining method, but after a few breaths, the Lock Demon Tower was completely refined.

"Boom!"

The Lock Demon Tower suddenly became smaller, and in just a breath, the Lock Demon Tower, which was originally towering to the sky, became only a few centimeters high, and fell into Lin Feng's palm.

Then it disappeared in a flash, directly submerging into Lin Feng's eyebrows.

With the same mind, Lin Feng finally figured out the situation in the Lock Demon Tower.

Such a lock demon tower that I don't know what grade it is, countless fierce beasts have been suppressed inside, and the lock demon tower is divided into nine layers, and every time it goes up, the level of the fierce beast will increase by one step.

Just in the first layer of the lock demon tower, the fierce beasts suppressed were many fierce beasts in the Yuanying realm.

"Isn't it......"

After figuring out everything, the excitement on Lin Feng's face instantly froze, replaced by an unprecedented dullness.

I thought I had seen a baby, but I didn't expect it to be a big pit.

After merging with the Lock Demon Tower, even if Lin Feng accepted the inheritance of the Lock Demon Tower, he had to open all the nine layers of the Lock Demon Tower within a certain period of time and control the fierce beasts inside, otherwise he would be devoured by all the beasts and die.

"Don't say it's opening the ninth floor, I'm afraid that if this first layer is not opened, it will be hiccup!"

According to the requirements, Lin Feng must subdue all the demon beasts in the first layer of the Lock Demon Tower within one year.

However, just in the first layer, among the hundreds of fierce beasts suppressed, there were more than a dozen fierce beasts of the Yuan Infant Realm. As for the rest of them, although they are much worse than the fierce beasts in the Yuanying realm, the weakest ones also have the peak of Jindan.

With Lin Feng's current realm strength, even the weakest fierce beasts inside couldn't deal with it, and it was even more impossible to subdue hundreds of fierce beasts on the entire floor.

"Master Lin, what's wrong with you?"

Su Longbow and Ruth were stunned, staring at Lin Feng for some reason.

Obviously refining a powerful magic weapon, but showing such a-eating expression, God knows what is going on.

"No, it's fine!"

Lin Feng sighed helplessly and didn't say much.

"Oh!" Seeing that Lin Feng was reluctant to say more, the two of them did not continue to ask.

......
