Hou Niao didn't insist. Shi Le was right; they weren't children and didn't need to be hand-held.
He also wanted to pass the next few years peacefully, harmonizing his abilities in all aspects.
Although the flying sword had been successfully cultivated and the self sword spirit was born properly, to unleash its greatest power, he still needed to compress the three-foot flying sword down to one foot, forming a sufficiently refined and dense golden energy sword.
The structure of the flying sword must be hard enough to be invincible, which is the first stage to complete now. After this stage is finished, he will need to find a large number of resources to reinforce the flying sword until it finally transforms from a void sword into a real sword.
But this process may have to be completed after the Core Formation. Now, he doesn't have enough time, and it's also difficult to find a perfect place like the Inner Warehouse of the Wu Sect.
