Before the flying boat's design could be refined to its optimal state, they would continue refining high-grade second-order flying boats.
Back when Wang Daoyuan was at the Foundation Establishment cultivation level, he had planted many second-order spirit trees within the Spirit Pearl Space, especially an abundance of Golden-thread Azure Spirit Peach trees.
After obtaining the Wood-Attribute Universe Gourd, he transplanted all those peach trees into it.
He also expanded their cultivation along the way, and they could now be used for artifact refinement.
Second-order spirit wood was exceedingly plentiful; refining several hundred high-grade second-order flying boats was nothing worth mentioning.
A few days later, the avatar refined another flying boat.
This flying boat was further improved upon the foundation of the Peng Bird Flying Boat. This time, the main alteration was the angle of its two wings.
A peng bird's flight posture was not set in stone. During ordinary flight, it always spread its wings as wide as possible.
When attacking, however, it always drew its wings in halfway.
The first Peng Bird Flying Boat had imitated the peng bird's ordinary flight posture, with its wings fully extended.
The newly refined flying boat imitated the peng bird's attacking posture, with its wings half-folded.
He once again took the flying boat out for testing, flying for the same half hour.
The first Peng Bird Flying Boat flew nearly twelve hundred li and consumed forty percent of its spiritual power.
The second Peng Bird Flying Boat flew nearly fourteen hundred li and consumed around fifty percent of its spiritual power.
This second Peng Bird Flying Boat was noticeably faster, but its spiritual power consumption had also increased considerably.
If Wang Daoyuan were using the flying boat himself, the Spirit Gathering Bead's spiritual power was inexhaustible, so naturally he would pursue speed alone.
