"Eterna Grana."

The moment it was activated, spikes after spikes coming out of the ground in all directions. Kai and the others had begun to retreat, so no one was injured, but it kept chasing them.

Suddenly, Rain appeared between them and summoned a barrier that was supposed to be stopping it. However, the spikes kept marching forward, not flustered by the barrier.

Only some of them hit the spikes and got destroyed, but since it traveled inside the ground, Rain couldn't do anything.

This time, Tasha and Kai tried to stop it. Kai simply carried Tasha with him while the latter released a few explosive marbles.

Boom boom boom.

A series of explosions occurred and destroyed many of the spikes. However, the spikes grew back as if nothing happened and kept advancing forward.

Ayaka followed the suits but to no avail. This technique never stopped.

"It's good that the magical beasts are dying, but if we let this continue, our side will suffer a serious loss too," Kai muttered while thinking of a way to escape from this situation.

"Kai…" Tasha called a name after coming up with a plan. "Can you listen to what I am saying?"

"Do you have a plan?"

"Yes. I am going to seal that protector's power." Tasha nodded with a serious expression.

"Can you do it?"

"Yes. Elder Rapakha told me the way. Although I couldn't seal someone stronger, the weakened him should be possible. Without any more power, the attack should stop. What do you think?"

"It's better than doing nothing. I will carry you there because there is no telling that the beast has the reserve power to hit you or not."

"I understand. I will be counting on you." Tasha smiled.

Kai nodded and shouted. "All of you keep running away. I will try to deal with it."

Without waiting for them, Kai already leaped above the spikes, using his Sound Blast. He made sure that he didn't touch a single spike because he didn't know what would happen.

Kai's movement was unpredictable, but he managed to get into the beast's range without any injuries.

Suddenly, Serta summoned two arms that were trying to grip him. However, Michelle and Rain had acted faster than anyone else here.

Michelle threw her Dark Version to help Alex while Rain summoned his barrier to stop the incoming two arms.

'I have never thought that the situation will become like this. Besides, I am afraid that his rise is something inevitable.' Rain narrowed his eyes while thinking. 'He will soon reach this level in the new future. '

Kai, on the other hand, hadn't put a thought in his next promotion. He simply desired to get stronger as quickly as possible, especially after seeing Tasha's strength.

The government would begin paying close attention to her, so he needed to have those four stars on his shoulder to protect her.

Having this important thought, Kai arrived on top of the beast as he noticed that Serta was still alive.

However, his eyes had lost their focus as he kept looking up even with Kai coming to his range of detection.

Kai destroyed all the spikes coming out of the ground while asking. "Tasha. You should do it because this will be our chance to end this battle."

"I know." Tasha nodded as she bent down, staring at Serta's body. She channeled her energy to his body as she overpowered the rampaging energy as if trying to break free from the control.

However, Tasha kept fighting. The pain transmitted to her brain forced a small groan to come out of her mouth.

Kai was dealing with all the spikes that came from their surroundings, so he could only ask without turning back. "Are you alright?"

"Yes." Tasha smiled and kept sealing more and more energy as she progressed until one point, Serta gave up.

The moment his real skin came back, Kai quickly stabbed it without showing any mercy as the monster ultimately died.

After making sure that the beast died, Kai roared while raising his sword.

"Uoh!"

"Uoh!"

The soldiers followed him, feeling happy that a monster like that died under Kai Carter, the rumored genius from the US Base.

"We might have killed one of our greatest enemies, but we still need to face more than three million monsters. Keep your movement sharp and we shall claim the victory." Kai let out a battle cry, which was followed by the soldiers.

Kai never really showed himself to the public, so no one knew other than those he had met in the Spirit World.

"Alright. Let's go. We help our brothers in need." Kai shouted because the giant was covering behind the tree. Kai had no choice other than to leave this guy alone.

"Uoh!"

Kai maintained the army first as he asked Rain and Brad for another mission. They agreed and began sweeping the enemies with Kai's strategy. It was proven to be effective, so they both had no qualms about the strategy.

Besides, without them realizing it, Kai had been maintaining morale this whole time. The soldiers never fell into despair, especially during a war.

It took them a whole week just to kill all the monsters, but everything was worth it. They sent a few air troops after the agreement and left everything in Kai's hand.

The battle continued. After all, even with the protectors running away, they were required to handle more than three million magical beasts. Luckily, Serta killed around two hundred thousand magical beasts during the last magic that disabled his function to move or talk. This made their mission incredibly easier.

Kai and the others chipped their number away little by little, making sure to kill at least a few hundred thousand in a year. With the rotation of Kai, Rain, and Brad, the armies could fight even longer. Some even kept smiling despite having gotten an injury.

This was how much the satisfaction was from having Kai in the army because they managed to grab a few good things.

He didn't forget about the explosive stuff that Rain brought with him, placing all those people up front, especially the jet." Kai smiled.

He couldn't contain his smile and used the air support, decreasing their number even further.

Despite being so warm and lucky, the result remained the same. Even though it was anticlimactic, the war had truly ended.

Kai quickly ordered all the soldiers to bring all the injured to get themselves healed.

Rain came to him, showing his respect in this battle. No matter what, his achievement was the most apparent in this war. He walked to his tent, finding Kai shaking Brad's hand.

It seemed Brad was thanking him for his service and apologized for all the harsh attitude this whole time.

Kai sent him off with a smile because he understood Brad's personality better during the way. Although he was a tough guy, there seemed to be a history and goodwill behind his action. He felt a bit bad for the former student council president, but Kai believed that a family problem should be resolved by both of them together, not an outsider like him.

Kai then turned around and looked at Rain. Brad also saw him and decided to let them talk alone, saying that he would handle the rest.

Rain and Kai closed their distance as the former stretched his hand with a smile.

Kai nodded and shook his hand.

"Thank you. I really need to improve even further because my current ability is lacking so much." He smiled.

"No, no. You are already strong enough."

He shook his head. "If I need to fight you or your sister, I feel like I won't have the chance to win. As for Michelle, there is a possibility because my Barrier Magic has an advantage to it. If it's on equal ground, I don't know if I will defeat her. I really need to improve because the enemies from this point on won't be that easy."

"Yes. I might not be able to control the entire situation like earlier. That's why we need to get stronger as soon as possible." Kai nodded in agreement. "Still, I am honored to have you accompany me in this battle."

"No, no. It's me who should feel honored. I have never thought that Ria Ross's student is a monster like herself. I thought I could stand a chance against you, but it seemed everything was just my wishful thinking."

"You shouldn't…"

"It's fine. Despite saying all this, I wasn't disappointed with the result. Instead, I will be using this motivation to keep increasing my power because I know that someday it is needed." Rain smiled and gently bumped Kai's chest and said. "You should keep improving because I might accidentally take your title in the future."

Kai smiled and nodded. "I will. Are you returning now, Commander?"

"Yes. My only mission is to help you during the war. Now that the war has ended, I need to return as soon as possible. Just make sure to clean all this up, alright?"

"I know." Kai smiled.

"I hope we can meet again." Rain shook Kai's hand once again.

"Yes. I believe that it won't take too long for us to meet again." Kai smiled and nodded before saluting. "Thank you for your support, Sir."

Rain saluted before turning around and walking away. "I am leaving then."

Kai watched how he entered the helicopter. It seemed that he had satisfied his own curiosity regarding Kai's achievement and power. At the very least, he had finished a problem.

Kai turned around and saw that the soldiers began cleaning up the beasts scattered all around the battlefield. He shook his head helplessly and walked to the front, planning to help them.

"This is going to take a long while…"
