After taking Koharu around the city and purchasing everything she needed, Xiao Feng finally returned to the hotel with Rem and Ram.
The clothes they had purchased earlier had already been delivered and neatly placed inside one of the rooms.
By the time they returned, the sky outside had begun to darken.
Koharu had spent the entire day walking around the city, trying different foods and visiting places she had never dared to enter before.
Although she looked somewhat tired, the bright smile on her face had never disappeared.
The moment they entered the hotel room, Rem and Ram began carrying out their respective duties without needing further instructions.
"Master, Rem will prepare dinner."
"Ram will assist Rem."
Xiao Feng nodded.
"Make something nutritious for Koharu."
Rem looked toward the little girl and smiled gently.
"Rem understands."
"Young Miss has eaten too little for a long time. Her body requires proper nourishment."
Ram nodded in agreement.
"Ram will prepare the ingredients."
The two maids entered the kitchen area and began working together.
Rem washed and prepared the ingredients while Ram controlled the heat and organized the tableware.
Soon, the sound of chopping vegetables and the pleasant aroma of cooking filled the room.
Meanwhile, Xiao Feng led Koharu toward the centre of the room.
"Koharu, sit down."
The little girl immediately obeyed and sat cross-legged on the carpet in front of him.
"Onii-chan, is something wrong?"
"Nothing is wrong." Xiao Feng sat opposite her.
"I'm going to give you something important."
Koharu looked at him curiously, "What is it?"
"A way to become stronger."
Xiao Feng raised one finger and gently touched the centre of her forehead.
A soft golden light flashed beneath his fingertip and a large amount of information entered Koharu's mind. Strange words, breathing patterns, energy routes and cultivation principles appeared one after another in her mind.
The sudden influx made her head ache. Koharu instinctively closed her eyes and placed both hands against her temples.
"O-Onii-chan..."
"Don't resist."
Xiao Feng immediately surrounded her mind with his soul power.
His gentle spiritual energy slowed the transmission of information, allowing Koharu to understand it without overwhelming her consciousness.
A few minutes later, the discomfort gradually disappeared and Koharu slowly opened her eyes.
She blinked several times, still trying to understand the unfamiliar knowledge now resting inside her mind.
"Onii-chan... what are these strange methods?"
"They are cultivation techniques," Xiao Feng explained. "They will allow you to become stronger and control the Gastrea virus inside your body."
"You saw me burning down those people, right? That's the effect of cultivation"
Koharu's eyes widened in surprise.
Xiao Feng however continued to speak.
"The first technique is called the Chaos Devouring Art. It can absorb the Gastrea virus inside you and refine it into power that belongs completely to you."
"The second technique will strengthen your body, while the third will protect and improve your mind and soul."
"If it works as expected, you won't have to fear turning into a Gastrea in the future."
Hearing the words, Koharu suddenly leaned forward and hugged him tightly.
"Thank you, Onii-chan..."
She didn't doubt Xiao Feng for a second and believed all of his words. Not because of his show of supernatural power when saved her but because he provided her a home, cared for her and protected her.
Xiao Feng gently rubbed her purple hair and smiled.
According to the system, Koharu should be able to get rid of her status as a Cursed Son after using these Cultivation methods.
Knowing this, Xiao Feng felt relieved. Although he had only known Koharu for a short time, he had already accepted her as his little sister. Naturally, he didn't want her life to remain controlled by the infection rate inside her body.
Koharu looked him then suddenly leaned forward and kissed him on his cheek.
"Thank you, Onii-chan. But Koharu doesn't have anything to repay. Koharu can only use her body as a promise. Does brother want it?" Koharu winked her eyes playfully.
After it could help her get rid of Gastrea virus, she knew that the cultivation methods Xiao Feng had given her were unimaginably precious.
Nothing in this world could completely eliminate the threat of the Gastrea virus. But Xiao Feng had casually given her a method capable of turning the virus into her own strength.
As for where the techniques came from or who Xiao Feng truly was, Koharu didn't care.
She only needed to know one thing and that was — Xiao Feng was her Big Brother, he wouldn't harm her.
"Who taught you these words?" Xiao Feng froze briefly and touched where Koharu had kissed. Then he smacked her forehead.
I want to be your Elder Brother but you want to be my wife. What's going on with this kid's head.
"Ouch!"
Koharu immediately covered her forehead with both hands and looked at him pitifully.
"Onii-chan bullied Koharu..."
"Don't change the subject. Where did you learn to say something like that?"
"From television." Koharu tried to act cute to get away.
Xiao Feng suddenly felt that the entertainment programs of this world were causing severe harm to innocent children.
Forget it, Forget it, I will teach her a lesson later. Cultivation is important right now. Let's not get into trouble.
Xiao Feng sighed helplessly.
"Stop learning strange things from television and start cultivating."
"First cultivate the Chaos Devouring Art and use it to refine the Gastrea virus. After that, practise the Chaos Body Refining Art."
"As for the Ancient Soul Technique, there is no need to rush. Your soul must first become accustomed to cultivation."
This time Koharu didn't make any trouble and nodded obediently.
"Yes, Onii-chan."
Xiao Feng breathed a sigh of relief then he adjusted her posture and carefully explained the breathing rhythm and circulation route once more.
Although the complete information had already been transferred into her mind, understanding knowledge and putting it into practice were two different matters.
"I will remain beside you. If anything feels wrong, stop immediately."
Koharu closed her eyes.
Following the instructions inside her mind, she gradually entered the cultivation state.
At first, nothing happened then a faint crimson energy emerged from deep within her body.
It was the energy contained within the Gastrea virus.
Under the influence of the Chaos Devouring Art, the previously violent and invasive energy began flowing through her meridians.
The technique devoured the viral energy and removed its chaotic properties before refining it into pure cultivation energy.
Xiao Feng's soul power immediately surrounded Koharu and he carefully monitored every change occurring inside her body.
The Gastrea virus had already fused deeply with her blood, organs, and cells. Ordinarily, forcibly removing it would have caused unimaginable damage. However, the Chaos Devouring Art did not simply extract the virus. It refined the it into energy while preserving the enhancements it had already granted her body.
Inside Koharu's body, more and more crimson energy emerged and her aura began rising rapidly.
One star Dou Zhi Qi
Two star Dou Zhi Qi
Three star Dou Zhi Qi
Four star Five Star Dou Zhi Qi
...
Her cultivation crossed several realms without stopping.
Xiao Feng's expression gradually became strange.
He had expected Koharu to improve quickly because of the enormous energy stored inside the Gastrea virus. However, this speed was still beyond his expectations.
It was even more ridiculous than him, a cheater. What he gained in years couldn't compare to what Koharu gained in just a day.
Koharu's aura continued growing and the energy inside the room became increasingly turbulent.
Xiao Feng raised one hand and created a barrier around them, preventing the fluctuations from spreading throughout the hotel.
In the nearby kitchen, Rem and Ram both paused but after seeing Xiao Feng raise the barrier, they resumed their work.
Time passed,
Half an Hour, One Hour, two hour,...
Rem and Ram had reheated the food several times but Koharu still hadn't woken up from cultivation.
This made Xiao Feng's worried. He repeatedly examined Koharu's body to make sure nothing had gone wrong with her cultivation.
Finally when Three hours were almost up, Koharu's aura suddenly surged.
Boom!
Powerful energy erupted from her small body and struck the barrier surrounding the room..
"Dou Ling?"
Xiao Feng eyes widened and he was shocked and speechless. He didn't expect Koharu to progress so much. He thought she would at most progress to Da Dou Shi.
Dou Ling was a watershed in the Dou Qi cultivation system, but she reached it so easily.
It seems this world can really help me grow. If I can absorb a lot of the Gastrea virus, maybe I can cultivate to high level Dou Huang.
As for Dou Zong, Xiao Feng didn't have any hope because this world simply didn't have that level of energy.
Unless he sucked the Earth's core dry, he couldn't break through Dou Zong here.
He was also relieved that Koharu finally had some protective power
A hint of heat appeared in Xiao Feng's eyes then it was suppressed quickly. He will check out the possibility for cultivation, later on.
A few moments later, Koharu slowly opened her eyes which briefly glowed crimson before returning to normal.
"Onii-chan, I feel so strong now."
Koharu could feel the explosive power in her body. Compared to before, she was more than just a little bit stronger. She had a feeling that she could now easily kill the Gastreas in the wild.
"Haha, you will get even stronger in the future. But first control your power. Or it will cause a lot of trouble."
"Also, your Sister Rem and Ram have reheated the dinner several times, it's time to eat."
Xiao Feng rubbed her head again.
For some reason, he was addicted to patting head.
