Lin Dong was escorted by Dean Shangguan Kazuo and several high-ranking officials of the academy to a valley of the academy.

The valley was hidden in a forest in the academy, it was too hidden here, if it weren't for the leadership of the dean and others, Lin Dong would never have found out that there was a valley in this place.

"Alright, Lin Dong. You can go in. Dean Shangguan Yifu pointed to a dark hole in the valley and said to Lin Dong.

"Enter this hole. ”

"That's right, but he's not really a hole, it's actually a passage into another dimension. You will have a trial there. If you succeed, you will be rewarded. Time is theoretically unlimited. But it only allows martial artists below the Supreme Realm to enter, so there is a possibility of starvation if you don't come out for a long time. ”

Lin Dong slowly stepped into the passage.

"Why is this kind of space passage so solid to step on? Lin Dong asked secretly in his heart.

Unconsciously stomped his feet, as if he was stepping on the ground.

It was a very long passage, and Lin Dong walked for a while before seeing the exit.

Seeing the red light in the distance, Lin Dong quickened his pace and ran over.

Finally, Lin Dong walked out.

Lin Dong's eyes were an extremely vast world, and Lin Dong couldn't describe the scene in front of him.

There seem to be deserts, forests, seas, mountains, and grasslands.

Lin Dong didn't understand why he saw five different landscapes appear in Lin Dong's sight at the same time, Lin Dong rubbed his eyes, still couldn't believe it.

"Is it a trialist? Huh, it's interesting," a vicissitudes of life and an empty voice echoed in the space where Lin Dong was.

Lin Dong hurriedly replied: "Yes, I am here to accept the trial. ”

"Since you are a trialist, let's prepare for the trial. I'll take a look, the Grandmaster Realm. Yes, boy, you got to that at a young age. It seems that the person who tried this time should be that person's apprentice. ”

The voice paused, "Alright, let's get ready for the trial." If the trial is successful, I'll tell you everything here. Don't wonder just yet. Wait until you successfully complete this trial. ”

Saying that, Lin Dong's eyes froze.

Lin Dong closed his eyes. When Lin Dong opened his eyes again, Lin Dong could find that he was already in a very small space.

"The content of this trial is very simple and crude, you can stay through the trial, and if you fail, it will only mean that you are not here. Lin Dong shouted loudly around: "Always tell me what the goal of this trial is, what challenges are you going to take on by locking me in this small space." ”

"Well, I'll explain to you reluctantly, your little space is surrounded by some simplified spatial barriers. As long as you successfully break it, the trial is complete. Remind you that there are two methods, one is to attack with the divine sense, and the other is to use the physical body to explode directly. Try it slowly yourself, start now. ”

After the voice finished speaking, it disappeared, and Ren Lindong didn't ignore how he shouted at him.

Lin Dong began to look at the space he was in. It's really uncomfortable, Lin Dong can't stretch his hands and feet.

Lin Dong tried to attack the surrounding spatial barrier slightly, but Lin Dong's attack seemed to be counterattacked.

What force Lin Dong used to hit the space, the space barrier shook back with what force.

After a few tests, the power of the backshock made Lin Dong's hands numb.

Lin Dong had no choice but to temporarily give up the physical assault and instead use the soul explosion in the empty spell to attack.

Lin Dong tried to concentrate his mind and used all the strength of his body to carry out a powerful soul explosion that focused on the fixed point, and then in the next second, Lin Dong fainted directly.

When he woke up again, Lin Dong didn't know how long it had been.

Lin Dong hurriedly shook his head and came to his senses.

Looking at the surroundings, Lin Dong had nothing to do about this space wall.

Psychic attacks can be rebounded. It really surprised Lin Dong.

"Master has won such a precious opportunity, and I can't afford to waste it. Lin Dong thought for a moment, then gritted his teeth. Decided to boldly spell it once.

Lin Dong took out the iron sword on his body first. Prepare to use the sword method to perform a ramming first.

Then give the barrier a full-strength soul blast, and a full-strength palm.

Lin Dong may suffer extremely much pain, and even faint as before.

But Lin Dong still decided to fight it. Lin Dong was unwilling to give up this trial directly.

At the moment of the shape sword attack, Lin Dong hurriedly released a soul explosion, and Lin Dong could now perform a maximum of one four-stage soul explosion attack.

It was accompanied by a sonic boom.

Although the barrier was not broken, Lin Dong found that he did not seem to be harmed by the backshock.

It seems that after the force of the barrier exceeds a certain range, the barrier will not be able to rebound.

This discovery made Lin Dong overjoyed.

Having found a way, Lin Dong hurriedly continued to attack a second time. But the cost is just too great.

Lin Dong only attacked the barrier three times, and Lin Dong was tired and panting, and he collapsed on the ground.

Without the physical strength to support it any longer, Lin Dong slowly leaned on this impregnable barrier and gasped for breath.

With such a desperate consumption, Lin Dong really couldn't bear it. And there is not much food left in the space ring.

Time passed little by little, and Lin Dong himself didn't know how many times he had attacked the barrier.

Finally, Lin Dong succeeded, and the barrier shattered in an instant, and Lin Dong returned to the place he had just entered, and there were still five different landscapes in front of him.

This trial greatly exercised Lin Dong's control over his existing abilities.

Although he hadn't experienced any actual combat, Lin Dong's strength was already very strong, and it should be more than enough to deal with the Supreme Realm.
