Early the next morning.
Minato took Nawaki, Kushina, and Mikoto to a valley outside Konoha Village.
"This is a trap training ground. As the name suggests, trap devices are set up everywhere in this valley."
Minato stood at the entrance of the valley and introduced to the three: "Before coming, I modified the devices here a little."
Saying that, he casually pulled out two sheets of paper resembling exploding tags, one blue and one red.
"This is a training tag I made. The blue one represents an ordinary exploding tag, sealing water inside."
"The red one represents a high-power exploding tag, sealing a small-power flame bullet inside. Although it won't cause disability or death, some physical suffering is inevitable."
Minato threw them casually. Two exploding tags flew out. One exploded into a splash of water, the splash range equivalent to an ordinary exploding tag.
The other one burst with a bang, exploding into a fireball the size of a human head.
"Next, you have to cross this valley alone. During this period, once you trigger a blue exploding tag and get splashed by water, it represents one death." Minato explained.
"What about the red exploding tag?"
Nawaki asked impatiently.
"Triggering a red exploding tag represents the death of the entire squad."
Minato said solemnly: "This also means that you killed your teammates and caused the mission to fail completely."
As the voice fell, the air suddenly became depressingly silent.
"In addition, there are some other traps in the valley, also divided into two colors. Red represents the most serious result."
Minato explained: "My Wood Clones are in the valley and will update traps in real time. Every time you die, the clone will bring you back to the entrance and change to the next person to enter."
"Then I'll go first!"
Nawaki clenched his right fist against his left palm, looking eager to try.
"Discuss it among yourselves."
Minato smiled gently and made a gesture of invitation.
The three negotiated. Nawaki would go first, Mikoto second, and Kushina last.
After the negotiation, Nawaki came to the entrance.
He looked serious and took a step forward.
Splash!
A splash of water exploded under his feet, wetting his clothes.
"..."
The air was silent for a moment, then Nawaki suddenly clutched his head with both hands, his face full of madness: "What is this?!"
Minato crossed his arms: "Nawaki, out~"
"Pfft hahahahaha!"
Seeing this, Kushina held her belly and laughed loudly: "Actually got solo-killed by an exploding tag! Too weak!"
Mikoto couldn't help smiling either. She didn't expect Minato to set up an exploding tag in such a place so casually.
The most speechless thing was that because the exploding tag exploded from the ground upwards, Nawaki's pants were wet, but his shirt was not affected much, making it look like he wet his pants.
"Damn it, stop laughing. You guys won't pass either!"
Nawaki sat under a tree beside the entrance with a dark face, waiting for the two to suffer.
"Let me try."
Mikoto took a step forward, her eyes instantly turning blood red. In the left and right pupils, a black tomoe rotated slowly.
Using exploding tags as traps required reserving a certain amount of chakra.
Although the Sharingan couldn't see through objects, it could observe chakra. So as long as they were not buried too deep, it was difficult to threaten her with exploding tags.
With Nawaki's lesson learned, Mikoto dared not be rash, carefully investigating the surrounding environment, and walked out more than twenty meters.
She stepped over a very thin steel wire, and then stepped on the fallen leaves.
With a soft click, the mechanism was triggered.
Mikoto's face changed, dodging backwards. In the next instant, dozens of wooden kunai were nailed to her previous position.
One of the kunai was nailed to the steel wire she stepped over before. A muffled sound came from the ground under Mikoto's feet, and the ground collapsed.
Even the distance of retreat was calculated?
Mikoto was surprised in her heart, but after all, having experienced the Chunin Exam, her on-the-spot reaction was much stronger than Nawaki's.
Almost at the same instant, she raised her hand and threw a kunai nailed to a nearby tree trunk.
There was a steel wire tied to the ring of the kunai. Mikoto pulled the end of the steel wire and flew towards the tree trunk with the force.
Flipping over and landing on a tree branch, Mikoto looked around and found camouflaged exploding tags everywhere around her, wondering why Minato was so obsessed with exploding tags.
Little did she know that Minato was also doing this out of helplessness.
To prevent Nawaki from following the footsteps of the original work, he had taken great pains.
Who would have thought that this kid stepped on the exploding tag he casually covered under the soil as soon as he started?
Minato doubted if he had some kind of exploding tag affinity physique.
Boom!
An explosion sounded in the valley.
After sneaking for more than fifty meters briefly, Mikoto stepped into the mud and detonated the chain exploding tags hidden in the mud.
"Failed..."
Mikoto sighed and pulled out her mud-covered foot.
A Wood Clone flickered beside her, put a hand on her shoulder, and the two instantly appeared beside Minato at the entrance.
Mikoto looked at Minato in surprise: "Is this... Space-Time Ninjutsu?"
"A little trick."
Minato smiled: "How were you eliminated?"
"Stepped into mud that looked like flat ground."
Mikoto was somewhat helpless: "The traps are really too dense, and many are chain traps. Got hit less than a hundred meters in."
"Not bad, surpassed someone's highest record of 0.6 meters." Minato comforted with a smile.
Nawaki's face turned dark, turning his head away and muttering: "I was just careless..."
"My turn, my turn!"
Kushina walked to the entrance of the valley, looking full of motivation.
"Watch me, Shadow Clone Jutsu!"
With a poof, a Shadow Clone appeared beside Kushina.
Then she pointed to the direction of the valley: "Go! Kushina No. 1!"
"Yes, sir!"
Without saying a word, the Shadow Clone launched a suicidal charge towards the valley!
Nawaki looked astonished: "Eh? Is there such a method? Damn it, why didn't I think of it?"
"This shows that Kushina's combat IQ is higher than yours."
Minato smiled: "But ordinary people can't use this method anyway."
Shadow Clones would split the original body's chakra equally. Although the remaining chakra would flow back after dispelling, under normal circumstances chakra could not be stored. Even if it flowed back, it would disappear quickly. It was still a considerable consumption for ordinary people.
Only chakra powerhouses like the Uzumaki clan could use it so unscrupulously.
However, this method alone was not enough for Kushina to cross the valley.
This valley training ground was two kilometers long in total. Although the traps in front were dense, they were just appetizers. The main event was still behind.
Bang bang bang!
Traps were triggered by the Shadow Clone one by one. Finally, after rushing out more than thirty meters recklessly, Kushina's Shadow Clone was blown up by dense wooden kunai.
Kushina walked unhurriedly through the safe path plowed by the Shadow Clone with its life.
Then she created another Shadow Clone and repeated the trick.
Boom!
The second Shadow Clone fell into a pit trap after walking more than ten meters.
The third Shadow Clone walked across a clearing, and Kushina followed not far behind the Shadow Clone.
Then with a bang, Kushina's main body was blown to a refreshing chill.
"Why is this again?"
Looking at the Wood Clone appearing beside her, Kushina looked puzzled: "Obviously the Shadow Clone walked past fine."
The Wood Clone laughed: "Who said traps must be preset?"
