Cut through the iron wall, and it is another world.

Chen Feng looked at the sentence engraved on the iron wall, and couldn't help but swallow and spit at the mouth.

He was completely relieved now, and he believed that Xu Yingying had already returned to the Ancient Academy cultivation ground safely. Because, of the two gates, the most dangerous one, was chosen by him.

It is an enclosed area with green walls above and under feet that shimmer with green light. But unlike the previous softness, this time the green wall was quite tough, and Chen Feng even used the Blood Soul Sword to stab it, and with all his strength, he could only pierce a hole the size of a fingernail. And the surrounding walls are peculiar black iron, and the defensive performance is also very good, at least Chen Feng's strength can't be split.

This enclosed space is square, more than ten zhang wide, and the space is quite rich.

However, Chen Feng noticed that these four walls were slowly shrinking inward at the speed of a turtle crawling. Although this speed is extremely slow, the situation is not optimistic, looking at this, in less than three days, Chen Feng will be squeezed into a meatloaf.

In addition, the first thing Chen Feng discovered was a very ordinary iron sword, which was covered with rust due to the long period of time. And next to the iron sword, there is a cheats book, with four big characters on it, Xuanlei Sword Duel.

Seeing this secret book for the first time, Chen Feng was overjoyed, he had obtained the Xuanbao Lotus in the Spirit Building Palace, and he didn't expect to get any gains when he came to this Xuanlei Hall again. However, it seems that he is indeed lucky, and he has obtained the legacy of the old man Xuantong twice.

Xuanlei Sword Duel, Lingwu Realm Martial Arts, Creation Martial Arts.

"Why is it that in the cultivation ground of this ancient academy, the remnants of the old man Xuantong are all the creation and transformation martial arts of the Lingwu Realm? The strength of the old man Xuantong is so strong, even if he can't reach the Heaven and Earth Mirror, but at least it should be seven or eight stars in the Grandmaster Realm, it can't be only the martial arts of the Lingwu Realm? This may be deliberately done by the five major academies, their purpose is to put the martial arts that these Jinbang students can use here, and they have been rewarded?"

One question after another appeared in his mind, but Chen Feng soon had no time to think about it, because he discovered the changes in the iron wall and discovered the words on the iron wall.

This is obviously a dead land, if you want to break through here, I'm afraid you have to cultivate into the Xuanlei Sword Duel in a very short period of time. He once cultivated the bone poison ** in a short period of two days, but it was not the same. This Xuanlei Sword Technique, but the Creation Martial Technique of the Spirit Martial Realm, is by no means easy to refine in such a short period of time.

Thoughts kept flowing, Chen Feng simply didn't think of a way, but sat directly cross-legged, opened the Xuanlei Sword Technique, and read it carefully.

Since the agency is located here, instead of wasting time, it is better to find rules and move. It's really not good, Chen Feng still has the Xuanlei Order on his waist, and the big deal is in a flash, although the final spiritual descent is very good, he can get two treasures, which can be regarded as a great harvest.

However, the only thing that Chen Feng couldn't let go of was that the better the battle with Li Lingyun, that was his ultimate goal. He endured for a long time for this goal.

Two days had passed in an instant, and Chen Feng had already memorized every move of the Xuanlei Sword Technique. However, the power of this creation martial art is boundless, but it requires the final epiphany, Chen Feng has tried to use it, although it is also powerful, but after all, it is only a prototype, and it is not powerful at all.

The iron walls around are compressed only by Zhang Xu. Chen Feng sat cross-legged on the ground, unable to stretch his arms flat.

It had reached the most critical moment, but he did not have the slightest fear, compared to before, he became more and more indifferent. Closing his eyes and concentrating, he didn't care about the slight touch of the four walls, Chen Feng actually entered the realm of selflessness at this juncture.

It's a self-sublimation, but it's also an adventure. Because, he has no time.

Hiss~

A black gas quietly permeated, and Chen Feng was confused about this. The black aura swirled up, centered on Chen Feng, forming a black tower-shaped silhouette.

When the four walls touched the Black Tower, they actually stopped, and then the two fought strongly. This kind of confrontation does not have the momentum of the collision of Wu Yuan's forces, but just a silent and secret contest. But what is amazing is that the black tower has always been as steady as Mount Tai, no matter how the iron wall exerts its strength, it will not move.

In Chen Feng's soul, a sword-shaped energy kept flipping through it, which was the true sword intent that he had just experienced. Xuanlei Sword Duel, you must have a true sword intent in order to exert its power. Even if you have an ordinary broken copper and iron in your hand, but you have the sword intent, you can also cut the sky and the earth.

"Xuanlei sword trick, one sword to cut the sky. ”

In the dark, the martial arts force in Chen Feng's body exploded instantly, and the blood soul sword behind him flew in response, and he grabbed it, and with a backhand sword, the red light broke through the sky, and the four strong iron walls were suddenly cut horizontally like tofu blocks.

Airplanes~

Suddenly, the light flickered, and an image of an old man appeared above Chen Feng's head, looking at the young man below who closed his eyes and raised his sword, the old man smiled happily. Immediately, the sleeve robe swung, and the scene changed instantly, leading Chen Feng to another world.

"Where is this?"

Slowly opening his eyes, Chen Feng found that he was out of trouble. And the place where he is at this time is even more beautiful and picturesque.

High mountains, Junsong, flowing water, waterfalls. Everything is natural, the sky is full of white clouds, and the birds are chirping in the ears.

At this time, he was sitting on a small raised boulder platform under the waterfall. Looking back indifferently, Chen Feng was shocked to find that behind him, on the dense small stone platform, it was "himself" who was sitting with his eyes closed.

There were a hundred Chen Feng, sitting here in unison and cultivating, and the scene was really amazing.

"The martial arts power here is so rich, even richer than the cultivation ground of the ancient academy, at least twenty times that of the outside world. Moreover, this cultivation speed seems to be a little too fast. ”

Chen Feng perceived it carefully, and found that his martial power was increasing at a terrifying speed.

"Is it the effect of the hundred?"

Chen Feng was at a loss, but there was no doubt that his current state was surprisingly good. At such a speed, Chen Feng believes that in less than ten days, he will definitely be able to make a breakthrough.

He had just broken through the Lingwu Realm Xiaocheng, and if he could break through to the Lingwu Realm Dacheng in less than a month, it would indeed be a miracle.

"Old man Xuantong, thank you for the gift!" Chen Feng's heart moved, and he arched his hand in front of him, although he didn't know if the old man Xuantong, who had been dead for many years, could hear what he said, but he was really from the bottom of his heart.

"Li Lingyun, wait, there are still more than ten days. In ten days, you will be discredited in the entire five courtyards. What you owe me, I will come and take. ”

Chen Feng's eyes were clear, he was already a little impatient. This time, he could finally let go of his hands and feet, and make a real end with that bastard bastard.
