Transmigrated in Uchiha Clan with Sign-in System Start with Rennigan

Going anywhere wouldn't be a problem.

After breakfast, after greeting his parents, Uchiha Kouki went to the Konoha Military Police to clock in for work and patrol the village.

It's worth noting that Uchiha Kouki wore large sunglasses, just in case. If a situation arose requiring the Rinnegan, the sunglasses would conceal his eyes from the enemy.

It was wartime, after all.

Passing the Hokage Building, Uchiha Kouki, feeling excited, activated the system: "System, check-in at the Hokage Building!"

"Ding! Congratulations, host! Check-in successful. Reward: Flying Thunder God Technique!"

Minato Namikaze's Flying Thunder God Technique!

Uchiha Kouki was thrilled; his body trembled slightly. This was an overpowered jutsu in Naruto.

With it, nobody in the ninja world could stop him if he wanted to escape, not even Kamui! This S-rank jutsu didn't even require hand seals.

It was incredibly convenient.

"Haha, with the Flying Thunder God, even as a genin, my safety is guaranteed. I can run if I can't win," Uchiha Kouki laughed. His patrol felt lighter.

"All Konoha Military Police, return to headquarters for a meeting immediately!"

After patrolling Konoha for about three rounds, Uchiha Kouki suddenly received an urgent message from headquarters.

"Could it be... a change in the war?" Uchiha Kouki wondered as he returned to the Konoha Military Police headquarters.

"But I'm just a genin. I don't need to worry." He dismissed it.

Soon, all the Konoha Military Police gathered at headquarters.

Captain Uchiha Fugaku, Shisui, and other high-ranking officers were present. Their faces were grim. The atmosphere was heavy.

"According to reports from the front, Iwagakure's ninja army is advancing on Konoha through the Land of Grass. They're likely making a desperate gamble."

"The situation is critical. We need to send reinforcements! We absolutely cannot let Iwagakure's army cross the Land of Grass!"

"Teams 1 to 7, with me to the battlefield. Team 8 will stay in Konoha! Everyone, move out!" Fugaku ordered after everyone had assembled.

"My luck's good; I'm staying in Konoha," Uchiha Kouki thought happily. He was in Team 8.

Uchiha Fugaku then personally led a large contingent of Konoha Military Police to the battlefield.

Large numbers of ninjas, led by elite jonin, also rushed to the front.

Even Anbu were deployed.

Konoha had almost depleted its forces, leaving only essential defenses.

Iwagakure's all-out attack was terrifying.

Even if they won, it would be a pyrrhic victory if Iwagakure crossed the Land of Grass and fought on Konoha's territory.

But this didn't concern Uchiha Kouki; he only needed to stay in Konoha and coast.

In the tense village, Uchiha Kouki continued his patrol nonchalantly.

Unbeknownst to Uchiha Kouki, in a small forest west of Konoha...

Crack! Crack!

A soft sound of earth shifting. The ground suddenly became like quicksand, and several heads emerged from beneath the surface.

It was Tsuchikage Ōnoki, along with Kitsuchi, and others.

They had used spies embedded in Konoha to kill the barrier team and used the Earth Hiding Technique to silently pass through all Konoha's checkpoints, infiltrating Konoha undetected.

After checking their surroundings, they emerged fully. More elite ninjas followed.

"Yōshi! We've infiltrated Konoha. Phase one, complete!" Kitsuchi said excitedly.

"Alright, let's proceed as planned. You three create chaos in Konoha to divert attention. I'll find Sarutobi Hiruzen!"

"If anything happens, retreat immediately, don't wait for me! I can leave anytime; Konoha can't stop me!" Ōnoki ordered confidently. As the only flying Kage, he had the confidence to say so.

"Alright, disperse!"

With Ōnoki's order, Kitsuchi and the others used the Body Flicker Technique and vanished, moving through Konoha.

Konoha had been on high alert for an hour; the streets were empty. Everyone was hiding in their homes, and shops were closed.

The Iwagakure ninjas were pleased; Konoha's high alert meant their plan had worked. Konoha had taken the Iwagakure feint seriously!

"I hope this plan succeeds," Kitsuchi thought as he carefully moved through Konoha.

"At this time, Sarutobi Hiruzen, as Hokage, is likely in the Hokage Building. Let's check there first." Ōnoki thought, using Super Lightweight Rock Technique to swiftly fly towards the Hokage Building.

Just around a corner, Ōnoki unexpectedly encountered someone – a Konoha Military Policeman. Ōnoki breathed a sigh of relief; it was just a child!

Undoubtedly, the Konoha Military Policeman Ōnoki encountered was Uchiha Kouki.
