Invicinble Colorless Butler

At the Golem Manufacturing Facility, it wasn't long after the academy students entered. Outside the entrance of that area, the soldiers saw a middle-aged woman with short whitish red hair walking over with two people wearing black robes covering their bodies. That woman was Brolia, a subordinate of a Divine Race named Rosier.

"Stop! This is a restricted area! Go away or we will be rude!" One of the soldiers warned her but Brolia kept walking towards them.

"Stop or..." Before the soldier could finish his words, his face was gripped by a large cold hand. The other soldiers who were guarding with him also had the same fate. Their heads were banged to the ground by the two black-robed people.

Boooooooommmmmm!

The commotion at the entrance drew the attention of the other soldiers. Suddenly the entire area was enveloped by a barrier that prevented outsiders from entering the area. It wasn't a barrier belonging to the Golem Manufacturing Facility, but a barrier made by the person who invaded that place. This makes communication from outside the facility cut off and other people cannot enter the area.

When Brolia walked into the area, she was already blocked by dozens of soldiers and fully armed golems. She looked at the golems in front of her one by one. Then something unexpected happened, the golems who had come with the soldiers suddenly turned to attack them.

"Aaah!"

One of the soldiers was blown away by the golem's attack and made the other soldiers quickly realize what had happened.

"What happened!?" One of the soldiers with a sword shouted in confusion.

"We didn't know! Suddenly the golems went out of control and turned to attack us!" The other soldiers answered him.

"Report this to the captain immediately!" The soldier with the sword gave an order to the person next to him.

"Yes!" The soldier quickly ran to the captain's place to report it.

In a building within the area of ​​the Golem Manufacturing Facility, a burly Dwarf was organizing his soldiers. He currently had a tense face due to the invasion by unknown people. Suddenly a soldier with a panicked face came to him.

"Report, captain! All of the golems that we had brought suddenly turned to attack the soldiers. The golems seemed to be controlled by the person who invaded this place!" The soldier immediately gave his report.

"What!?" The captain was startled and stood up from his seat. He looked at the soldier and directly gave his orders.

"Quickly report this to the castle! I want the king to know immediately about this invasion!" The captain gave orders to the other soldiers.

"That...I've tried it several times. But we can't connect outwards. It seems that someone is isolating this place." The soldier replied frantically. The captain hit the table in front of him because he felt the current situation was very dangerous.

"Gather all the free soldiers! We're going there!" The captain took the big hammer behind him. It was the weapon he used to fight.

"Yes, captain!" The soldier quickly ran out and started gathering the soldiers.

Return to the area where the invasion has occurred, all the soldiers had been defeated by the golems hijacked by Brolia. She walked towards the Golem Manufacturing Facility.

"I'm sure those academy students are there. One of them must have that thing." Brolia had already inspected the building that had previously been attacked by Rosier's golems, but the object they were looking for was no longer there. Then she got a report that before the thing she was looking for disappeared, the students of the human academy paid a visit to that place. So she concluded it was carried by one of them.

But on the way she was blocked by soldiers and one of them was a captain who was guarding the place.

"Who are you!? What do you want from this place!?" The captain asked angrily after seeing that many of his men had died.

Brolia didn't answer his question. She just moved her hand and all the Dwarven royal golems she controlled started attacking the soldiers.

"Argh! What is this!? Why did the golem get stronger!?" One of the soldiers was injured by the sword slash from the golem. The soldier knew how strong the golem that attacked him was, he was confident of defeating it. But unexpectedly, the golem's power increased to an absurd level.

"Damn you!" The captain charged forward to attack Brolia head-on. He ignored the other golems that came attacking him. He knew the best way to subdue the golems was to defeat Brolia. The captain of the soldiers had the strength of a Hammer King. He was one of the strongest people in the Dwarven Kingdom.

The captain swung his hammer at Brolia. He swung the big hammer like it was nothing. The swing of the hammer was the same as the swing of a swordsman but heavier and more powerful. Brolia would fall apart if she was hit by the attack directly, but she seemed to have ignored the attack and didn't see it at all. The captain grew angrier at being belittled and added strength to his hammer.

"Die!" The captain was aiming for Brolia's head. He felt his attack must have hit Brolia quite heavily, but suddenly two people in black robes appeared in front of him. One stopped his attack and the other attacked him. The captain had no time to defend and had to receive a crushing blow from the black-robed man. He was blown away tens of meters until he crashed into the adamantium building wall.

"Ugh!" He felt all of his bones breaking with just one strike.

(Who are they! That black-robed person is at least a saint if he can hurt me like this!)

The captain tried to stand up from there. But his body screamed because the wound he received was not light. Before he could stand up, a black-robed person suddenly appeared in front of him and gave a follow-up attack that made him lose consciousness.

"Rubbish." Brolia walked towards the Golem Manufacturing Facilitywhere the academy students were on their study tour. After arriving in front of the large entrance, she was shocked by the security system in front of her. The soldiers guarding the place were no longer there because they had been deployed to confront her earlier.

"Interesting. Break that door!" Brolia ordered the two black-robed people. The two of them shot a laser beam simultaneously at the entrance.

Boooooooommmmmm!

The multi-layered security entrance was smashed to pieces. Brolia entered and looked around the inside of the place.

"Quickly find those academy students!" Brolia gave the second order to the two black-robed people. The two of them instantly responded to her orders and went deeper into the facility area.

"I need to find that thing quickly. I don't want Miss Rosier to wait too long." Brolia walked in a different direction from the two black-robed people.

"Heroes from another world, I think it's time for you to do your duty and prove that you are worthy of being called Heroes." Ziel looked at the heroes who were confused by the sudden warning sound.

Kyouka immediately realized something after hearing his words. She knew that the warning sound was a sign of impending danger. But she did not know what danger suddenly came at such an important time.

"What are you doing!?" She stared coldly at Ziel because the situation happened so suddenly when they were about to ask him something important. What's more, the boy in front of her seemed very calm about the situation.

"What am I doing? Haven't you been following me since I got here?" Ziel asked her back.

"You..." Kyouka wanted to say something but Hikaru stopped her. He also wanted to ask him but this was not the time.

"Kyouka, we can ask him later. Right now the most important thing is to quickly check what happened. If what he said is true, then the other students will be in danger." Hikaru reminded Kyouka.

"Okay." Kyouka reluctantly agreed. But before she left, she said something to Ziel.

"I will come back again and look for you! You better not run away from us because we will find you wherever you are hiding!" Kyouka left with the other heroes after saying that. Sintaro glared at Ziel before he left.

When Ziel saw the heroes had completely left, he jumped on the head of one of the biggest golems there.

(Lilith, stay with Clara. Don't leave her alone)

Ziel contacted Lilith through her communications boss.

(I understand! Are they coming again?)

Lilith quickly answered him. The 'them' she meant was the divine race.

(Yes. But it doesn't seem like the main god like you. That person is very good at hiding her presence)

Ziel answered her honestly. Ever since he entered that place, he had already sensed the arrival of Brolia and the two black-robed people who were with her. But her strength is not at the Lilith level. At the same time, he also felt the gazes on him coming from the hiding heroes. At that time, he thought of using them against Brolia. If they succeed, their strength as a hero will be doubled. In addition, they will also be recognized by others as people who deserve the name of a hero.

(Alright. If there is anything else please tell me immediately)

After that Ziel and Lilith's communication was cut off. Ziel also contacted Clara afterward to inform her of the situation. Then he saw the golems in this place suddenly move and attack the soldiers. The golems were controlled by Brolia, the middle-aged woman walking at the very back of the golem group.

"You're here, Ziel!" Kalya came and landed right next to him.

"How did you know I was here?" Ziel asked her. He hid his existence perfectly. Others would not be able to sense any mana, aura, or sign of life from him. Ziel also didn't contact her and tell her his position.

"A girl's instinct, maybe?" Kalya smiled jokingly at him. She could see his face softened after hearing that.

"Okay, stop kidding." Ziel reached out his hand and flicked her forehead.

"Ugh... Alright. Silphy told me." Kalya finally said honestly. Even though she was holding her forehead like she was in pain, but she had a big smile on her face. She was happy with how Ziel treated her.

"If you are here, where are the other teachers?" Ziel didn't see the teachers in that place. He also did not check their whereabouts one by one.

"Ah, they're fighting a golem that suddenly attacked the students." Kalya slowly clings to him. What she was currently doing became a habit for her and all her movements looked very natural.

"Then why are you here?" Ziel doesn't know how she got here when the other teachers are looking after the students. The teachers should be in a different room from where they are now. When danger occurs, they will come to protect the disciples in this place. But right now only Kalya is seen coming to help.

"They are scattered all over the building to help the soldiers suppress the golems that go out of control. By chance, I got the job of guarding this place." Kalya blinked her eyes and wrapped her arms around Ziel.

"In the first place, the golems weren't out of control but hijacked by someone else. You have to be careful when you have to fight them." Ziel said seriously to him. Ziel's words warmed his heart.

"I understand!" Kalya smiled like a blooming flower. She rested her head on his shoulder. But suddenly she remembered something.

"Ziel, when I came here I saw the heroes coming out and heading towards the entrance of this building. Is it alright?" Kalya already knows that Ziel is from the same world as the heroes. That's why she thought that he would be worried about their situation.

"They did have to fight it because they were summoned to this world for this reason." Ziel doesn't have any bond with the heroes even though they are from the same world. After all, it is their duty and other people have no right to forbid what they should do.

"Don't you want to help them?" Kalya looked directly at Ziel. Their faces were now very close. They could feel each other's breath.

"For now, no. They have to go through a life-and-death battle to grow. If they keep being helped, they won't be able to do anything. So there's no point in summoning them. I don't know if they will survive after fighting them or not. After all, to get something, sometimes you need sacrifices." Ziel understood what she meant by asking all those questions. But right now, he was under no obligation to help them.

Kalya could feel something sad from his words even though her poker face didn't change at all. She didn't ask any more questions and tightened her grip on his arms.
