If he could eliminate his enemies early without any detriment, then he would have done so as soon as possible. None of the 100 of them would have left that hall because there was no rule against fighting in the assembly hall.
The protection phase doesn't mean they can't sabotage each other though. That's why she attacked him. She wanted to interrupt the process of establishing his base so that he wouldn't be the first.
She screamed at him, "Let go of me you weirdo."
Her head is in the ground so she can't speak with her mouth even if she has a mouth. What she is using to scream at him is her divine sense and it is very loud.
Unfortunately, loudness isn't going to deter him. He asked her as he pressed her head deeper into the ground, "Why are you calling me a weirdo?"
"You're weird because you're translucent. You look like cloudy glass instead of like white beautiful ceramic."
"That makes sense." He said in understanding as he kicked her head very hard. "But I am stronger than you so my looks don't matter. If I had the opportunity, I would turn you into a seat for making fun of my looks."
She yelled in pain but she didn't shut up. "How can I be strong like you?"
Legion-5 sneered. "You can't be strong like me. The best you can do is to choose the warrior class and be able to take a beating because the next time I meet you, I will beat you to death. You can only prepare yourself to take a beating without dying quickly."
He was stomping on her as he spoke to her. Each stomp caused the ground to explode and her body to be pushed further in. If not for the protective barrier around her, she would be the one to explode not the ground.
Others came around soon after and saw him with his foot on her. The three of them decided to avoid him and rush towards his growing base to disrupt it.
"So you want to gang up on me."
He sneered and picked up rocks on the ground. Then he threw them at all three of them. The three stones smashed into them like artillery shells.
They didn't die despite the explosion. The stone should have torn through them and critically injured them but it didn't because of the shield that appeared at the last moment. Instead, they were stopped dead in their tracks and they were blown back. The force that he used to throw the rocks was that strong.
But he didn't stay idle. He picked up the first enemy by her ankle and flashed to one of the three stunned enemies. The one he approached was already standing up.
"I wish I could kill you insolent brats," He said as he bludgeoned the second enemy with the first.
The two supreme beasts slammed into each other and created a powerful shockwave. The ground beneath them was cratered because of the clash.
He shook his head and muttered, "Talk about the ground suffering when two elephants clash."
The two enemies aren't strong enough to damage the ground like so. They ought to smash each other to pieces. But the barrier around both of them clashed in the process of protecting them. It is the clash of the barriers that created the shockwave.
He shook his head and picked up the second enemy. Then he rushed towards the third one and slammed them against each other again. He did it for all of them. Then he carried all four of them and buried them. He placed them on the ground and stamped on them with all his might. Their barrier protected them from damage but the ground wasn't so lucky. It caved in so they were pushed into the ground.
More Supreme beasts came to find him burying the first batch of enemies with his foot. They didn't have eyes so their whole body twitched when they felt the resounding shockwaves. The ground was literally quaking with each stamp of his foot. The Supreme beasts are tough nails that he can't kill. But that doesn't mean he is helpless against them. He will just hammer them into the ground like the tough nails they are.
He smirked at the new batch and taunted them, "Who wants to have a go at me?
Then he warned them with a grin, "Beware that you don't end up like them."
They can feel his taunt through his divine sense. He wanted them to know just how much fearless he was. They have to take that into consideration if they want to sabotage him. Of course, he could be bluffing. But there are four people on the ground who will be delayed from setting up their bases right now.
Some people decided to leave. They went for the two adjoining hexes and began fighting for it. Some of them formed alliances to lay claim to the precious spots. But some remained standing some distance away from him.
He threatened them, "Leave now or join them on the ground."
One of them spoke up, "I want to form an alliance with you. You are strong but it is impossible to defend yourself alone."
Legion-5 laughed. "Form an alliance with you?"
"Of all the people that I could form an alliance with, none of you riffraffs are worthy."
They became angry immediately but he didn't bother to listen to any more of their dregs.
"I told you to leave." He roared as he attacked.
Rocks flew around like artillery. He shot down the Supreme Beasts from the sky as if he was shooting down birds. The sounds of collision also sounded like explosions. Then he approached them and beat as many as he could before they flew away in fright.
He watched them run away with disdain. Then he laughed again.
"What nonsense. What a joke. Why will I form an alliance with weaklings?"
