All the people inside the city felt heavy vibration as a blinding lightly erupted above the city. The aftershocks of the explosion were dangerous. Luckily, they were inside the city barrier, or else they would die with the exception of a few powerful individuals in the city.

After a few moments, the giant ball of flames disappeared and it revealed Bargan's figure along with the rest of the seven-circle officer.

Huff!

Bargan lifted his hand and wiped the blood on his mouth. He was breathing heavily and he had burn marks on his body.

'This is the reason why I don't want to use my inner spell close to me.' He thought as he glanced at the figures of the seven-circle officers. Bargan's inner spell was so powerful to the point that it became a double-edged sword to him.

In normal circ.u.mstances, he could cast this spell and control it so that he wouldn't receive any damage but this situation was an emergency. If he didn't use his inner spell then he would be put at disadvantage.

Still, it's been a long time since he fought someone that could make him used his max power. These people from Seven Deadly Sins were really strong. He couldn't imagine how powerful the Sins.

Yuvn and the rest of the seven-circle officers were full of burn marks all over their bodies. Yuvn's left hand was slowly turning into ashes. His comrades were suffering the same condition as him. In fact, their condition was worse than him.

The temperature of the area around them was so high. It was higher than the temperature of the magma. The extreme atmosphere dissolved any creatures around them. No one could survive this harsh environment unless they were above A-rank.

"Too strong... Even with blessing..."

There was a hint of fear in his eyes but it quickly disappeared when he recalled their objectives.

The four people who casted the [Great Teleportation] spell were lying on the surface of the city barrier. Half of their body was burned into crisp. Their power wasn't enough to completely block Bargan's attack so they suffered.

Bargan didn't care about them. He knew that they were going to die and their injuries wouldn't heal easily unless there was an S-rank healer in their group. But from what he saw, he could guess that there's no healer in the seven-circle group.

He slightly opened his palm and flames burst out of his body. These flames have healing properties so it could heal some of his wounds to a certain degree. Still, it's not enough to completely heal all of his injuries caused by his inner spell.

Yuvn opened his eyes widely when he saw this. "This guy has healing ability! Hurry up and disrupt him!" He shouted before charging towards Bargan at extremely high speed.

"Hmph!" Bargan snorted as also charged towards them. He was afraid of fighting them. He knew that he had the upper hand in this battle.

Boom! Boom!

They wrestled in the sky at extremely high speed.

...

Souta arrived at the control room of the Institute. He saw that some of the remaining teachers were already here. They were talking to each other.

"Teacher, what happens here?" He asked as he approached the group of seven teachers.

The teachers turned their heads when they heard a voice behind them. They find Souta, the top 1 ranker in the first year, walking towards them.

"Oh? Souta, what are you doing here?" One of the teachers asked.

"I came here to check why did the institute activate the protection barrier around it. I want to leave this place and check my legion. So what happened here?" Souta replied to them. Even though he had a general idea about what occurred here he still had to ask to avoid suspicion.

They didn't immediately answer his question. After a while, they decided to answer him. He was a student of this institute, after all. So he had the right to know what happened here and maybe Souta could help them.

"We don't know what happened nor we know who activated the barrier." The teacher paused for a moment before he added, "This door to the control room is locked. Our ID didn't work so we couldn't open this door."

"Hmm..." Souta walked in front of the metallic door and looked at the rectangular object beside the doorknob. He then turned to the teachers and asked, "Teacher, can I borrow your ID?"

"Here..." One of the teachers passed his Teacher's ID to Souta.

They were the weakest teachers in this institute but their strength was still at the peak of B-rank. Clearly higher than the group of B-rank that Souta fought in the legion war.

Receiving the ID, Souta recalled that group of B-rank. In one on one battle, he wouldn't be able to win against them. Ramie and him exchange blows at that time and he was the one who received injuries.

Well, Souta didn't kill them. They were not bad people. If they didn't treasure their comrades, Souta wouldn't be able to use that trick against them.

If they didn't care about their comrades then he would kill them even if he had to use [Soul Blood Mode] and [Possession] at the same time.

Either of these two choices the result will be the same. That fight became a warning to the people that have some ideas against his legion.

Souta shook his head and placed those thoughts in the back of his mind. It's not the time to think about those things.

"Let me see..."

He placed the ID that he received in front of the rectangular object. The rectangular object was a device used to verify the ID of the teachers. It will check the magical runes that were imprinted in the ID if they have the authority to enter the control room.

After a few moments, the verifying device emitted a red light indicating that they didn't have the authority to enter the control room.

"See... We couldn't enter the control room. Every student didn't have the authority to enter the control room, so only teachers could enter it. There's no exception to it." One of the teachers explained to Souta.

"Someone changed the verifying method. I don't think that we could enter the control room using the normal method." Souta said while shaking his head. His knowledge about this was close to none. He could hardly build a magic circle without the system's help so how could he write the runes inside the verifying device.

He stood up and said, "We should find someone who is experts in runes." He then glanced at the control room. He knew that it was impossible for them to forcibly enter this room.

This room was filled with layers of barriers. A B-rank like him couldn't break it. The teachers too wouldn't be able to break it as they were only a peak B-rank.

Oh? He recalled one person who have the power above B-rank. If he wasn't wrong that person was in the bas.e.m.e.nt according to Teacher Bargan.

It's time to find Yanagi Shina.

He wondered what she was doing at this moment.
