The Treasure Chest System With Its Infinite Mysteries

The people of Tiansun College were looking at the scene in front of them with fear in their eyes. The mountains and plains were filled with spiders that were as huge as houses, and they were resting all over the place.    

Each spider had eight legs that were as sharp as blades, and eight dark green eyes on their heads. They were emitting a terrifying murderous aura.    

Green Eye Spider Devil!    

The most common demonic creatures in Void Devil Domain had terrifying reproductive abilities, and there were even more of them.    

As soon as the people from the Tiansun College appeared, the green eye Spider Devil that covered the mountains and plains all let out ear-piercing screeches. It was endless, and the densely packed green eye Spider Devil instantly flew towards the Tiansun College.    

The eight legs of the Spider Devil turned into afterimages, and they erupted with a sharp light that filled the sky. It ripped apart the sky, and its power was terrifying.    

If it was in the outside world, just the aftermath of the sharp light would have turned the entire valley into dust. However, the mountain range within the Void Devil Domain was countless times sturdier than the ones in the True Martial Continent. The power unleashed by Devil Soldier's devil couldn't even break a mountain.    

The people of Tiansun College had never seen such a scene before. Each of them cried out in shock. Some of them even had fear in their eyes, and subconsciously wanted to escape.    

But at this time, a shocking aura burst out from Su Jin's body. It instantly jolted everyone awake, and all of them looked at him.    

"Don't panic, form the Raging Flame Battle Formation!"    

Su Jin stood firmly in the void and shouted.    

Everyone took a deep breath. That's right, they had practiced the Battle Formation for half a day, and now they could use it.    

Under Su Jin's control, there were a total of forty-seven Martial Ancestor students, and they were all arranging their armies and formations.    

At this moment, the army of green eyed Spider Devil was just a mile away from them. In the blink of an eye, they had arrived in front of the Tiansun College's students.    

"Flaming Slash!"    

Su Jin shouted.    

Everyone's facial expression changed, and the true qi in their bodies started to surge out.    

"Fire!"    

Everyone roared in unison, and a terrifying Zhen Qi burst out from their bodies.    

Boom!    

In the air, an incomparably huge flaming saber appeared in the sky above the battle formation. The raging flames were like a huge flaming warship that seemed to melt the sky.    

A black mass of green-eyed Spider Devil pounced at them. In an instant, it was able to tear dozens of students into pieces.    

But at this time, the huge flaming saber cut through the air and landed in the green-eyed Spider Devil army.    

Hiss! Hiss! Hiss!    

Immediately, countless miserable cries sounded out. A boundless sea of flames spread out from the center of the green-eyed Spider Devil army. Wherever it passed, the green-eyed Spider Devil would be devoured by the sea of flames. In an instant, not a single corpse was left behind.    

In an instant, at least a few hundred green-eyed Spider Devil died on the spot.    

In the battle formation, everyone was shocked by the scene in front of them.    

Could that strike just now have been unleashed by them?    

Everyone could only feel disbelief. The power of this slash was so powerful that even an ordinary Martial Lord Stage Expert wouldn't be able to unleash it. It was actually unleashed by dozens of Martial Ancestor students.    

Shock, pride, and wild joy!    

Pride filled everyone's heart.    

This was the first time since they became students of the Tiansun College that they felt they could become so strong.    

Everyone couldn't help but look at Su Jin. They knew what was going on.    

All of this was done by him.    

Without Su Jin, they wouldn't have been able to create such a battle formation.    

Everyone's eyes couldn't help but reveal a look of respect.    

At this moment, many of the senior students who were originally dissatisfied with Su Jin's radical actions had completely abandoned their prejudice.    

There was nothing more important than raising their strength.    

However, at this moment, Su Jin did not look at these students. Instead, he snorted coldly. "What are you all standing there for? Fire Bull, charge into the formation!"    

Everyone reacted. Although they had heavily injured the green-eyed Spider Devil army, there was still a large pile of them left.    

But at this moment, there was no longer any panic in their hearts. They all listened to Su Jin's orders and quickly changed their formation.    

Rumble!    

Boundless flames surged out from the battle formation and transformed into a huge flaming bull that was as large as a mountain. It was extremely violent.    

The huge flaming bull let out a huge roar, and then suddenly rammed into the green-eyed Spider Devil army.    

Outside the Spider Devil Valley, a group of a hundred people were approaching.    

Almost all of these people were injured. Some of them were even wearing tattered armor, looking extremely pathetic.    

However, everyone had a joyful smile on their faces.    

They were the students of the Tianqi Academy, and they had just experienced a great battle, so they were able to obtain a bountiful harvest.    

Now, they were preparing to head to the Spider Devil Valley and complete the mission of collecting Spider Devil crystal cores.    

However, just as they arrived outside the Spider Devil Valley, they could feel the world-shaking fluctuation and the miserable cries of countless demons.    

Everyone's expression instantly froze, and they were overwhelmed with shock.    

At the front of the group, a pretty girl had a shocked expression on her face. She looked at a tall and handsome man who was standing beside her, and asked in surprise, "Head, who is fighting inside? Why is the battle so intense?"    

This man who was as handsome as jade was none other than Head, Pan Lei. He was at the first Martial Lord Stage, and was also the only Martial Lord Stage Expert in the Sixty Year Cycle.    

The Tianqi Courtyard was ranked among the lowest in the Vast Qi Academy. It was already very rare for a Martial Lord Stage Expert to appear.    

Pan Lei's talent was naturally outstanding, except for the Myriad Sword Pavilion, which only recruited Sword Dao experts. The Qilin Association and Senluo Hall had invited Pan Lei, but he was determined to help the development of the Sky Qi Courtyard. He rejected the invitations of the two major powers.    

At this moment, Pan Lei's expression was solemn as he looked towards the inner part of the valley. "This battle formation is comparable to a battle between sixth or seventh Martial Lord Stage warriors. I have never heard of such a powerful warrior in the Sixty Year Cycle."    

"It's very possible that it's not a single person, but a group of people."    

At this moment, a scholarly young man spoke. His eyes sparkled as he said, "I can feel the fluctuations of the battle formation."    

"Battle formation?"    

Pan Lei and the beautiful woman were both stunned. Then, an envious look appeared in Pan Lei's eyes. "Battle formation can allow a group of martial artists to display strength that exceeds their own. Such a good thing, only the Array Formation Masters of the top institutions can have it. "    

"The people inside are probably the top five academies. We shouldn't go in for the time being. We'll wait for them to come out before going in, so as to avoid any misunderstandings."    

Pan Lei instructed.    

Everyone nodded and held their breaths as they rested on the spot. However, everyone pricked up their ears and listened to the battle waves inside. The more they listened, the more shocked they felt. That terrifying fluctuation... One after another, countless Spider Devil were killed.    

After a while, the fluctuation finally stopped.    

Everyone heaved a sigh of relief. The battle inside had finally come to an end. At this moment, they heard a group of footsteps approaching. The eyes of the students from the Tianqi Academy lit up. They all wanted to see which branch the students from. The Heavenly Kui Academy, Tiangaang College, or the Heavenly Sword Academy?    

There must be a lot of Martial Lord Stage Expert warriors in their team who could unleash such a powerful battle formation.    

After all, although the battle formation was powerful, it also depended on the person who formed it to have outstanding strength.
