Tang Feng came mainly because he saw a transcription in the ancient books.
West God's travels.
It recorded a secret that in the passage leading to the Outer Domain Secret Realm, there was a free-floating energy crystal. If you obtained it and fused it onto your war armor or divine ship, it would get upgraded, and the gravity suppression of the Outer Domain would no longer be a problem.
The key is that this thing is quite difficult to obtain.
That West God discovered it by chance.
Using divine fruit to attract those energy crystals, he was also accidentally thirsty and witnessed a magical scene. Utilizing the crystals he acquired, he roamed the Outer Domain and returned safely.
This is why Tang Feng wanted to take a trip.
Thus, even when reaching the Outer Domain, he wouldn't worry about the risk of being crushed by energy.
However, it's not easy to get this spot, it's all emperors coming, and some are very deeply hidden old relics.
