He didn't make a single battleship to be the designated paragon as that would make it stand out and be targeted by her. Instead, he used the combined amplification to randomly empower the battleships.
So the designated paragon was always changing. This caused the empowered battleships to be random while the other battleships on the light side without defense tried to avoid the world god while simultaneously attacking it.
She noticed the change and laughed maniacally. "Hahahah. You have no choice now but to watch me slaughter them."
She began to kill the battleships again. Now that they have substituted their defense mode for overdrive, they have become vulnerable to her power. She was even destroying them faster than before because of her excitement. She did this as one of them occasionally dipped into the dark side to fight her main body.
The ones that occasionally dipped into the dark side produced power beyond the limit of the dark side, but it still couldn't threaten her main body. It made her both impressed that an Origin god could come down to the dark side to fight her and smug that this Origin god had bitten more than he could chew by fighting her.
She said proudly, "A shortcut cannot compare to the true path of power."
She is winning by a landslide both on the light and dark side. The only flaw in her success is that she can't take the source of the power of the battleships. She used the entire power of her Will, but the unique Authority of the void universe inside the battleships refused to budge. She also failed to freeze them so the battleships could heal themselves after she destroyed them.
That didn't discourage her, though. More blue stars rose from the dark side to join her avatar. They are her avatars, which she can produce at the cost of some energy. This way, she will be able to destroy the battleships faster.
This is just the surface battle. Another battle is going on on the dark side between the battleships and the world god. The main body of the world god is on the dark side just beneath, and if she doesn't leave, she will just make more and more avatars to destroy the battleships. She intends to do that, but a pesky battleship is interfering with her.
The battleship would sink into the dark side, where the pressure of reality is too much for weak beings to bear. This battleship didn't get destroyed by the pressure, as she expected. It even attacked her with power beyond the limit of the light side. This attack is more powerful than the ones on the light side, so she had to take it seriously.
She defended against the attack, only for the battleship to return to the surface. Then another battleship sank again from another location one second later and released an attack greater than the previous one.
Monarch High Heaven was far away from the battle on both sides of reality. He was aware of everything going on and was also directing them with his full focus.
The combination of the battleships took time, as one battleship fused with 10, then 10 fused with 100, and then 100 fused with 1000. Next, 1000 fused with 10,000. The power of the enhancement doubled with each successive stage of fusion. Each stage needed a second, so each second led to the doubling of the power of a single attack of the random battleship that dipped into the dark side.
At 3 seconds, the amplification was at 8 times. That increased to 32 times at 5 seconds. The main body of the world god on the dark side couldn't block the attack at this point anymore. She was finally pushed back.
"Interesting." She said as she was smashed back.
Things weren't as simple as being pushed. Her physical body is actually cracking. This is just 5 seconds after the overdrive mode was activated. But the augmentation wasn't over. 1,000,000 battleships had fused together at the 6th second for an augmentation of 64 times. So the attack tore a hole through her main body immediately.
This attack was so devastating that it reached her world and cracked the continent within it. Millions of living things died, and her Will weakened drastically. This means she surely won't be able to defend another attack of that caliber, or even weaker. So it was a wise move for her to run.
Fortunately for her, the battleships have a large, glaring weakness. They need one second between each action. They can only attack once every second or combine once every second. That one second is more than enough time for her to escape far, far away.
This development didn't affect the battle on the light side much. The avatars had weakened, but they continued to destroy the battleships. They might even continue to do so if her main body is destroyed.
The avatars are temporary channels or containers of the Will of a world god. They will remain in existence as long as there is energy to maintain the channel on the light side and as long as the Will of the world god exists. And since they are on the light side, they can't be destroyed easily like the main body.
The battleships have to wear down the avatars and make them run out of energy if they are to kill them. The good news is that without the main body to reinforce them, the avatars are on their own. They won't be replenished once they run out of energy.
The immediate benefit of puncturing a hole through the main body of the world god is that she stopped freezing the space around them. It meant that the realm lord could now open portals to summon reinforcements again.
Monarch High Heaven did that immediately. More and more battleships came to surround the three avatars on the light side. They were able to grind the avatars down before their numbers reached a billion.
