As an otaku, Sun Xiaozheng could only fantasize about anime wives, game beauties, and living a carefree life.
He never thought he could travel through time.
When he opened his eyes, touched his face, jumped, felt his heartbeat and breathing, and looked in the mirror.
"Oh my god!"
"I turned into Sasuke?"
"Are you kidding?"
"I'm not dreaming!"
Sasuke pinched his thigh. "My god, it hurts."
In Naruto, although Sasuke is the second male lead, his handsomeness and popularity are not much less than the first male lead, Uzumaki Naruto.
"Wait!"
"What time is it now?"
As an otaku who used to do whatever he wanted in his dreams, he was not panicked at all when he really traveled to the world of Naruto.
First, he checked his own cultivation.
"No!"
"Where is the system that is required for a time-travel drama?"
Sasuke called out, "System!"
Unexpectedly, a transparent system page popped up in the void, accompanied by a voice: [Host, I'm here.]
Sasuke sighed. "What a user-friendly system."
[Thank you for the compliment, host!]
Sasuke asked, "What type of system do I have?"
"How do I complete the task upgrade?"
[Answer, host. Your system is called the Invincible Sign-in System. You only need to trigger the sign-in to get the invincible reward.]
Sasuke exclaimed, "I like this system. The sign-in system is simple and fits my lazy and laid-back personality."
"So, where should I sign in next?"
The system replied: [The Invincible Sign-in System does not directly issue sign-in tasks, but like the big world of "Genshin" game, the host needs to explore by himself.]
Sasuke did not expect it to be an exploration-type sign-in system.
"Will it be difficult?"
[Not difficult.]
The system said: [By touching your fingers, you can complete the hidden exploration tasks and get corresponding rewards.]
Sasuke nodded.
"Okay, I'll try."
Sasuke looked around the house and did not successfully sign in.
"It still looks a bit difficult!"
At this time, his eyes were a little itchy, and Sasuke rubbed them with his hands.
Unexpectedly, the system directly prompted: [Congratulations on signing in successfully, reward: Sharingan upgrade, Eternal Mangekyō Sharingan.]
Suddenly, Sasuke's eyes were burning, as if he had opened a source of energy.
"Fuck!"
Sasuke was stunned on the spot.
"So simple?"
"If I touch my eyes, I can sign in, and my Sharingan has been upgraded successfully?"
"666."
Sasuke was very excited. This was the beginning of the Eternal Mangekyō Sharingan. His future life was unimaginable.
Sasuke immediately continued to explore himself.
Hands and feet, there seemed to be no prompts.
When he touched his dantian.
[Ding Dong.]
[Congratulations on signing in successfully by touching the chakra, and the reward: chakra upgraded to the Jonin level.]
In an instant, Sasuke's whole body of dantian gushed out terrifying chakra.
Warm all over, Sasuke felt that at this moment, he could kill an elephant with a full-strength punch.
"I'm so strong!"
Sasuke was so happy.
Sign in to the Sharingan and get the Eternal Mangekyō Sharingan.
Sign in to the Chakra and get Jonin-level Chakra.
"It's worthy of being an invincible sign-in system!"
Now, in this Naruto world, I can do whatever I want!
"Gagaga~"
Just when Sasuke was so happy, there was a knock on the door.
Sasuke opened the door.
He saw a girl with long pink hair outside the door. She was petite and cute, wearing a red slit cheongsam-style long skirt, which outlined her slender and attractive figure.
"Haruno Sakura..."
Sasuke was a little surprised. At close range, Haruno Sakura's delicate skin was so soft it could be blown away. Her white and rosy little face was shy like a girl.
Wow, this is a real anime beauty.
Taking a deep breath, he could smell the girlish fragrance of Haruno Sakura.
"Sakura, what do you want to do with me?"
Sakura's words shocked Sasuke.
"Sasuke, I like you. Can you be my boyfriend?"
Sakura blushed and shyly handed over the food she bought.
This...
Starting with an invincible sign-in.
A beautiful girl confessed her love!
It's a bit exciting!
Sasuke thought that if it was Sasuke in the original series, he would definitely not agree.
But~
He was a time traveler, so he would not be as rigid and boring as Sasuke in the original series.
"Well, Sakura, from now on, you are my girlfriend."
