I believe that the bastiodon will be reborn as a honedge so that it can be the sword and shield of Alex's team

It's not worth reading this crap. MC's character is terrible. He's an asshole who thinks he can do anything. The romance in this FanFick is forced and I don't feel good when there has to be a scene after about 50 chapters...... go figure. And the worst thing is that the author has hung a halo over the MC's head and everything he does must bring him only benefits and literally give him all the best without any flaws, and even if the MC encounters a problem, such as soul problems or the death of a loved one, the author will solve this problem in 2 chapters. I won't mention the harem, the fucking herem, I read 150 chapters of this shit just because I hoped it would improve or reduce the amount of this harem shit and fucking but no, to sum it up I don't recommend it .

Yes, you are right, but hypothetically, if someone creates 80 shadow clones and tells them to learn the same thing, his learning progress will not be 80 times faster, the individual clones' progress may repeat. Additionally, when learning something complex and mastered to a certain degree, minor changes will be added. What I mean is that the clones' memories will overlap and be remembered as one memory. And new improvements with such a complicated technique will not be great. Although I must admit that such a number of memories may be somewhat burdensome for the user.

True, but in the arc of the wave he created a lot of them. But that was the beginning of Naruto. But I will only add that learning seals does not burden chakra reserves that much.

Actually , kakashi used quite a few of them at the end of the wave arc

There's no need to worry about the lack of chapters, I'm sure this little break will be good for thinking about the further plot
