The book I recommend to you is the Supreme Divinity of Taihuang. It's a fantasy novel. If you want to read a story about time travel and a powerful protagonist, this novel will definitely attract you. As for the question of joining the Xu Family, I personally suggest that you make a decision based on your own preferences and standpoint. After all, this is your choice. I hope you like my recommendation. Muah ~
One great Percy gains power fanfiction is 'Percy's Ascent'. In it, Percy discovers an ancient power within himself through a series of trials. It's really exciting as it shows his growth from a normal demigod to a super - powered one. Another one is 'Power Surge Percy' which focuses on Percy getting a new kind of water - based power that no one has seen before.
If Naruto gains the power of Beerus in fanfiction, he would become extremely powerful. His already impressive combat skills combined with Beerus' god - like power would make him nearly unbeatable. He could easily defeat the toughest of foes in the Naruto universe with a single blow.
If Naruto gains the abilities of Kratos in fanfiction, he would become extremely powerful. Naruto already has his own set of powerful jutsu, but with Kratos' abilities like superhuman strength, enhanced combat skills, and his rage - fueled power, Naruto could defeat almost any enemy with ease. He might be able to take on stronger foes like Kaguya even more effortlessly and protect the Hidden Leaf Village in a much more dominant way.
In a fanfiction where Naruto gains One for All, there are a lot of possibilities. One for All gives the user enhanced strength, speed, and durability. Naruto already has a great deal of experience in combat and a strong will. This new power would allow him to face stronger opponents with ease. For example, he could take on the Akatsuki members more easily. Also, the way he trains and how he passes on his knowledge to others might change. He could potentially teach his friends how to better utilize their own powers in relation to One for All's abilities. His relationship with Sasuke might also be affected as they would have to re - evaluate their power levels in comparison to each other.
If Naruto gains a Zanpakuto, it would completely change the power dynamics in the Naruto universe. Naruto is already extremely powerful with his chakra and Sage Mode, etc. A Zanpakuto would add a whole new dimension to his combat abilities. He might be able to use its unique powers in combination with his shadow clones, for example, sending clones out with the Zanpakuto's special abilities to surprise opponents. It could also potentially give him new ways to deal with different types of jutsu and enemies.
Well, he'd probably become super powerful. The symbiote suit could enhance his physical abilities like speed, strength, and agility. He might also gain some new jutsu or combat techniques based on the nature of the symbiote. For example, if the symbiote has some sort of dark or shadow - like property, Naruto could incorporate that into his attacks, making them more unpredictable.
Well, in a fanfic where Naruto gets the reanimation jutsu, it would change a lot of things. Naruto is a character who values life highly. He might struggle with the moral implications of using such a jutsu. On one hand, it could be a great strategic advantage, but on the other, it goes against his principles. He might use it in a very different way than others, like only bringing back those who died unjustly to give them a chance to right the wrongs.
Well, in the 'naruto gains kyuubi's powers fanfiction', Naruto might face new challenges as well as new opportunities. On one hand, he would be a target for those who fear his new - found power. On the other hand, he could use this power to protect his village better. He might also develop new techniques that are a combination of his own skills and the Kyuubi's power, like a new type of shadow clone jutsu infused with the Kyuubi's chakra.
Naruto might get a Zanpakuto that complements his existing powers. Since he has a strong connection to wind chakra, it could be a Zanpakuto with wind - based abilities. Maybe it could create powerful tornadoes or slices of wind that are sharper than his normal Rasengan - infused attacks.
Well, Naruto would become extremely fast. He could zip around the battlefield in an instant, catching his enemies off - guard. His combat style would change drastically as he could now close the distance between him and his foes before they could even react.
