After curing her, Ethan went outside of Earth.
The origin artifact he got from winning the tournament was a Sword.
Ethan took the artifact and entered the Sun.
It previously was the place where Erebus lived. Now it was empty.
The Sun was the center of the entire solar system.
He placed the sword inside the Sun and activated its protective domain.
Soon, a spherical sword domain started to spread 360°.
First it covered the Sun, then Mercury, after that Venus, then Earth, Mars, Jupiter, Saturn, Uranus, and at last Neptune.
Then it started going beyond that. After leaving the area of the planets, it reached the Kuiper Belt, then the scattered disk, and after that the Oort Cloud, which was up to 1 light-year from the Sun.
This was the whole solar system.
After covering the Oort Cloud, the domain stopped.
It was now a fortress which could only be breached by a Universe Realm powerhouse. Under that level, everything was totally safe.
