Chapter 619

After Kitazawa finished lunch with Kosuke Maruboshi and Kakashi Hatake, he couldn't wait to return to the office.

Once the idea of modifying the medical forbidden jutsu: Physical Regeneration appeared, he even chose to give up his lunch break.

Kitazawa sat in the office chair and took out paper and pen.

The medical forbidden jutsu: Physical Regeneration was a system reward, so its proficiency was maxed out.

He also had master-level chakra shape transformation and proficient-level Yang Release chakra nature transformation, so even a forbidden jutsu could potentially be successfully modified.

But Kitazawa still underestimated its difficulty.

A lunch break passed, and he didn't have any substantial progress.

But Kitazawa wasn't in a hurry.

It was an S-rank ninjutsu after all, so it naturally wouldn't be modified successfully so easily.

Medical ninjutsu has existed for over a thousand years, and to this day, no medical ninjutsu for limb regeneration has appeared in the ninja world.

From this, one can know the difficulty of this matter.

Kitazawa glanced at the time and came to the school playground.

Just sitting still is useless; he should go do what he needs to do, and maybe inspiration will strike suddenly.

Kitazawa continued to learn Water Style: Great Waterfall Jutsu, and also split off a shadow clone to learn Leaf Style Swordsmanship with Kosuke Maruboshi.

It was another uneventful afternoon.

After school, Kitazawa went home.

But to his surprise, Tsunade had already returned home early and was standing at the door waiting for him.

"Lady Tsunade."

Kitazawa stepped forward to greet her.

Tsunade didn't answer, just crossed her arms and stared at him.

Kitazawa looked left and right, feeling the same pressure as her clothes.

What is the situation?

He didn't remember offending Tsunade recently.

"Do Itachi know about Shikkotsu Forest?"

Tsunade was silent for two seconds and asked.

"It is one of the three holy lands for summoning beasts."

Kitazawa's heart moved, and he replied.

Could it be that Tsunade intends to let him become a contractor for Katsuyu?

"Contractor ninjas can summon summoning beasts through the Summoning Jutsu."

Tsunade said slowly, "But a few summoning beasts can summon contractor ninjas through the Reverse Summoning Jutsu."

Kitazawa was slightly startled, and soon understood.

In the original work, the Reverse Summoning Jutsu could only be used by the snakes, toads, and slugs of the three holy lands for summoning beasts.

Undoubtedly, not only can it save a lot of travel time in normal times, but it can also save lives at critical moments.

"Sign your name on it."

Tsunade took out a huge scroll and said.

"Is this the contract scroll for Shikkotsu Forest?"
