Xu You's hand didn't stop, and with a flick of his fingers, two more forbidden birds flew out, at exactly the same angle as just now, and stuck on the metal wall that was getting closer and closer.

Terrifying sword light continued to shoot out from the wall, bursting into the opposite wall, and the dazzling light bloomed, making an explosive and sharp sound.

Li Wei and the four of them were stunned, and then they realized that Xu You used this way of attacking the shield with his own spear to break the untouchable and indestructible copper wall, which was really ingenious.

As the two metal walls approached, they were less than ten meters apart from each other, and the distance became shorter and shorter as they moved faster.

Xu You's face was as calm as water, but he kept urging the forbidden birds, triggering the sword light attacks of the metal wall one after another, using the strength of the formation itself to deal with the formation.

This is also a blessing in misfortune, fortunately, the Huo family had such a setting before the battlefield formation, otherwise he would not be able to use the mana of the formation, he might be able to stand alone in the fourth-level formation, but he would not be able to take care of the thoughtfulness of Lin Yongan and the four of them.

Finally, when the spacing shrank to less than two meters, there was a boom, and the two metal walls could not bear it, and at the same time, two huge holes were shot out by the incomparable sword light.

"Keep up. Xu You stopped releasing the Ten Thousand Laws Source Forbidden, and instantly turned into an afterimage, but he drilled out of the hole in the metal wall behind him.

Lin Yongan and the four of them were trembling in their hearts, and they were overjoyed when they saw this, so they hurriedly followed behind him and also got out of the hole.

Lin Songmei is the last one, and she has just come out of the hole. The hole in the metal wall returned to its original shape at a rapid pace, and then slowly collided with another metal wall.

Silently, the two metal walls collided, and there was no earth-shattering sound, but they merged together, without the slightest stop, and crashed in the direction of the five people again.

After drilling out of the hole, the front of the five people was not an endless smooth road, but a metal wall.

However, the wall is not infinitely long, only thirty meters long. at both ends of the wall. Each has two metal walls perpendicular to it, and the perpendicular opposite places are not connected, but have two exits, as if they were the two ends of an alley.

The thirty-meter-long metal wall was crashing into them at a rate of one meter per breath. The infinitely long metal wall behind him also sped up. No more than five breaths. The five of them will be squeezed into a lump of pulp.

"To the left. Xu You didn't hesitate at all, he kept pinching the spirit decision in his hand, and led the five people to the left exit. In less than a moment's time, he ran to the left exit.

But when he was still one step away from the exit, his footsteps suddenly stopped, almost causing the four Lin Yongan who were galloping behind him to bump into him.

Whoosh ...... The terrifying sword light shot out from some direction, like a wave of light, quickly sweeping through the left exit.

Seeing this, Lin Yongan and the four of them immediately swallowed the words they were about to ask, if Xu You stepped out of the mouth just now, the five of them would have been ejaculated into a sieve.

After three breaths, the sword light of the match stopped. Xu You didn't hesitate, turned around and didn't enter the left exit, and the four mermaids behind him followed.

In the last breath, the thirty-meter-long metal wall and the infinitely long metal wall collided and merged with each other.

After turning out of the left exit, a 20-meter-long metal wall appears in front of you, and there are also two metal walls more than 10 meters long on the left and right, perpendicular to each other, and one of the metal walls is connected to the other to form a T-shape, which creates three exits.

The three walls, together with the infinitely long wall behind them, form a small labyrinthine space, and then each squeeze towards the five people at a constant speed.

Xu You still didn't hesitate, and ran directly towards the exit in the middle.

The four of them were dazzled, and they couldn't tell the difference between southeast and northwest, so they could only follow Xu You and run away. However, they can also vaguely distinguish that Xu You is by no means a random choice, but a choice after careful deduction.

What if they had a different exit? I was curious, but I didn't want to try it.

"Captain, the walls here shouldn't be very high, can't we fly over?" Guo Ling couldn't help but ask.

"You can give it a try, you must not fly halfway, and you will be shot into a sieve by the sword light, isn't it the captain. Without waiting for Xu You to answer, Lin Songmei stabbed him.

"It's not going to be shot into a sieve by the sword light. Xu Youtou didn't look back and said, "But the speed of the impact of the wall is directly proportional to our height from the ground, only when standing on the ground, the speed will be the slowest, if you fly high, the wall will also move faster, and it will definitely sandwich us into meat before you fly out." ”

"Thankfully, I didn't do this stupid move. When Guo Ling heard this, he couldn't help but smile bitterly.

Soon, the five of them dodged into the middle exit, this time, Xu You did not stop, and there was no sudden flash of sword light at the exit.

As soon as he stepped out of the exit, as expected, there were several metal walls facing each other, this time forming five very different exits, and then crashing towards the five people at the same speed.

"It's a labyrinth. Lin Yongan couldn't help muttering.

"It's a maze, every time you choose an exit, it's equivalent to a gamble, if you bet right, you may take a step closer, and if you bet wrong, you will lose everything. Xu You said lightly and rushed towards the second exit.

Before reaching the exit, his footsteps stopped abruptly again, and in an instant, another devastating wave of sword rushed through the exit.

But after the sword surged, Xu You did not immediately walk out of the exit, but continued to wait.

After a breath, a heavy footstep sounded, and as the ground shook violently, a golden-armored giant as high as a metal wall slowly walked past the exit.

Its two brass bell-like eyes glanced coldly at the five of them, then continued walking, and then sank into the metal wall next to it, forming a huge metal relief, and remained motionless.

Xu You then raised his feet and walked out of the exit.

Lin Yongan and the four of them were dumbfounded, and at the moment they were stared at by the golden-armored giant, all four of them had a chilling feeling, as if they were being targeted by a powerful spirit beast.

This golden-armored giant is definitely a metal puppet at the level of the Spiritual Light Realm.

As soon as he turned out of the exit, several metal walls collided again behind him, and then merged silently. In front of the exit, there are movable metal walls arranged according to the maze.

Xu You led the four of them forward again, still choosing to exit without hesitation.

Gradually, as the five of them went deeper, the labyrinth of metal walls grew larger, more complex, and faster moving. At the beginning, it was only one breath and one meter, and it gradually increased to one breath and two meters.

Moreover, the metal walls are no longer static, but are constantly merging and merging in motion, which causes the exits to no longer be fixed, but are constantly changing.

This undoubtedly poses a greater challenge to Xu You, because there is only one correct exit at a time, and once the exit changes, if you don't have time to rush out, then there is only a dead end in the metal wall maze.

And he is not alone, he has to take care of the No. 1 team and keep everyone safe and sound, which requires that the action must not only be fast, but also accurate, and in some places, even half a breath can not be delayed.

Fortunately, Lin Yongan and the four of them are also elites, although they have come here, they are completely ignorant of the formation, but they can still accurately implement Xu You's orders, and they can concentrate on deducing the changes of the fourth-level formation.

As the exit of the labyrinth continues to change, the attacks of the metal walls are also escalating, and from time to time, inexplicable sword shadows will shoot out from the metal walls, or the metal reliefs will suddenly turn into gold-armored giants.

There were even fourth-level spirit beasts formed by metal.

Some of these obstacles are real, some are false, they are just illusions, true and false, and it is extremely difficult to distinguish between them. But under Xu You's precise deduction, they all avoided the past one by one.

The five of them are like five cats, running quickly on the active crater that released Mars, and every step is likely to be swallowed by danger, but they pass through the gap in the flames with precision without losing a single bit.

At this time, half of the other squads had already begun to face formation attacks, but what they encountered was nothing more than some relatively simple difficulties such as ice blades, snow arrows, fire and rain traps, etc., which were very different from what Team No. 1 faced.

Even the team that advanced the fastest, Lu Xinyan, Huo Zhengyang, Ye Xiu and others, encountered more and more powerful formation attacks, and they did not have the fireball attacks that Xu You and others encountered in the first wave.

In the stands, there was already an uproar.

From the moment Team 1 encountered the metal wall, everyone was stunned.

There are monks who know the formation, and they can recognize it at a glance, this is a typical gold fourth-level formation, and the attack power is super strong.

Unexpectedly, after encountering the strongest third-level formation attack, as well as two "random" fourth-level formation attacks, the Huo family didn't have time to come up with an explanation, and the battlefield formation actually directly applied a fourth-level formation attack to the No. 1 team.

It's simply unthinkable.

This is like a group of Spiritual Light Realm cultivators taking action against the five Soul Realm juniors.

However, what is even more surprising is that Team No. 1 was not swallowed by the fourth-level formation at the first time, but under the leadership of Xu You, it continued to advance deeply, and not even a single injured person was injured.

It's just against the sky.

Even the fourth-level spiritual light realm powerhouses such as the Chenyang Sect Master, the Iron-Blood Sect Master, the Zheng Family Master, and the Qingyun Sect Master were also full of horror, because even if they went up in person, they might not be able to achieve the same level as Xu You.

This junior is only a Soul Realm cultivator, and he is not yet in the middle of the Soul Realm, how can he ......

The crowd found it incomprehensible.

Of course, it is incomprehensible to be incomprehensible, and if there is such a serious mistake in the battlefield formation, even mortals can see the difference. Everyone questioned the Huo family one after another, asking for a reasonable explanation. (To be continued......)
