Chapter 300
The three-headed alien considered attacking the Milky Way Star Lord for three reasons.
Firstly, the Milky Way Star Lord had only recently reached the ninth rank. No matter how powerful he was, how strong could he be? The alien was a ninth-rank ten-thousand-layer powerhouse.
Even if the Milky Way Star Lord was incredibly talented, he couldn't kill the alien, who had every confidence of being able to retreat safely.
The Insect Race Grand Alliance and the Human Alliance were mortal enemies anyway, so attacking the Milky Way Star Lord wouldn't change their animosity. If the Milky Way Star Lord had the chance, he wouldn't hesitate to kill the alien.
Secondly, the Mysterious Yellow Secret Realm was primarily entered by avatars of powerful beings. The Milky Way Star Lord likely did the same. If it was just an avatar, he wouldn't have any heavy treasures or ultimate defenses.
The alien wouldn't risk attacking the true body of the Milky Way Star Lord, knowing human civilization would have many safeguards in place. But in the secret realm, dealing with an avatar seemed manageable.
Thirdly, the Insect Race's rewards were highly tempting. They were willing to go to great lengths to slow the growth of the Milky Way Star Lord.
Meanwhile, Lin Yuan easily killed the hundred-meter-tall giant bear, taking the 'Mysterious Yellow' crystal.
The giant bear was only at the entry-level of the ninth rank, and its core 'Mysterious Yellow' crystal was only the size of a thumb, worth less than a few thousand universe crystals.
