Chương 742: Chapter 440: Return to the Outer Realm_2

Although many people in the real world don't even have the opportunity to go to the Outer Domain Space, understanding some common knowledge about another world can still be helpful to them... actually, Lin Yuan didn't know what use it could have.

But Sun Hua was very curious about everything in the Outer Domain Space.

So, Lin Yuan just cooperated with him.

Spirit Qi Bomb, the cutting-edge weapon of the technology series.

Sun Hua was indeed right, this thing was indeed powerful, but making it wasn't really complicated.

At least, Lin Yuan had learned it quite accurately in a short time.

During this period.

A large number of Spirit Qi Bombs were placed at the entrance and exit of the Outer Domain Space.

Wang Yuanfan still didn't understand and specifically asked Ji Xuanya what was going on.

Ji Xuanya indicated that it was Lin Yuan's instruction, he descended to the real world through the Remnant Consciousness Whisper and communicated with her.
