At this point it is clear. boruto This is a series where Naruto Uzumaki needs to greatly improve his overall strength.

This would require significant upgrades for Naruto Uzumaki, and given the fact that Sasuke Uchiha gained tremendous strength during this timeskip, these upgrades are already a reality. At one point in Boruto, Sasuke fails to scratch Jigen in battle despite support from Naruto Uzumaki. But as we clearly saw in Boruto: Two Blue Swirls In Chapter 5 on December 20, 2023, Sasuke was able to seriously wound Code and take out his eye without even the Rinnegan, despite Code being much stronger than Jigen. Apparently, Sasuke trained with Boruto during the time skip and achieved a higher level of power. This practically confirms that Naruto Uzumaki will also grow in strength after his return, and one of the ways he could potentially do this is through the use of scientific ninja techniques.
From the beginning to now boruto In the series, scientific ninja technology became a pillar of the story. In fact, Naruto Uzumaki even tried out a unique scientific ninja tool in . boruto September 11, 2017 Chapter 16. In this particular chapter, Katasuke develops a mechanical prosthetic hand specifically for Naruto. These hands possess tremendous power and are essentially a copy of Momoshiki Otsutsuki's Rinnegan.
“This is a hand created by Katasuke using data from his previous fight with Otsutsuki. Using this, you can absorb all of your opponent's jutsu, but unfortunately, you cannot reverse the jutsu just yet.” — Naruto Uzumaki explains his new prosthetic hand prototype in Boruto #16.
For those of you who don't remember, Momoshiki had the ability to absorb any form of chakra from his hands and become his own chakra. Another ability he could utilize with other Rinnegan was to expel this chakra by making it many times stronger. While the absorption portion of this prosthetic arm is working perfectly, Katasuke is still undergoing expulsion work, and it has been officially confirmed that this prosthetic arm is still a prototype and is being further developed.
Three years have passed since then, and it's very possible that this prototype is now fully developed. This means that when Naruto Uzumaki returns, he could potentially utilize this new Otsutsuki jutsu to make him incredibly powerful.

These two gods are getting incredibly close to each other, and one of them will be the next to fall.

The wait will still be long, but we know it's coming and we'll have to prepare for Naruto Uzumaki's power-up as well.
“Something is going on. It's something only you and Sarada can solve. That's what my intuition tells me, and that's why I mentored you.” — Sasuke Uchiha to Boruto Uzumaki in Chapter 5 of Two Blue Whirlpools
When Naruto returns, one of the easiest ways for him to become stronger is to utilize this new prosthetic arm based on the powers of Momoshiki Otsutsuki. Considering that there is still a genius scientist Amado in the village, the possibility that this hand will be given to Naruto is even higher. Using his high intelligence, this prosthetic's banishing ability would also have been perfected. This means that Naruto will officially be in charge of the powerful Otsutsuki Rinnegan Jutsu. He can then use it to greatly enhance his own strength while also taking down powerful enemies of Otsutsuki level.
