Ever since obtaining the Gravity Barrier and successfully setting it up, Uchiha Kiyoshi had begun experimenting with it nonstop.
The Gravity Barrier was extremely effective, but without a Saiyan physique, Uchiha Kiyoshi could only take it slowly. He estimated that even 1.1 times gravity would require two or three months of adaptation before he could begin training at higher levels.
The Hardening Technique did not conflict with the Gravity Barrier. The two could function at the same time, but their effects merely added together rather than multiplying as he had imagined.

After experimenting for several days, Uchiha Kiyoshi gave up using the Hardening Technique as support. When cultivating the Body Forging Technique, he used the Gravity Barrier instead, training every day under the maximum gravity he could withstand while still practicing the Body Forging Technique normally.
However, he had not neglected training the Hardening Technique. Though it had been eliminated from his Body Forging Technique regimen, this Ninjutsu still had many other uses.

Uchiha Kiyoshi felt that before his body entered
