During this year Xiao Feng taught the cultivation method to everyone.
He didn't have any reservations and taught all the skills that he knew including earth and heaven-level fighting skills. He taught Seitenshi in private and spent a lot of time with her.
The girls practiced very seriously and the Gastrea virus in their bodies was eliminated on the first day. Their Cultivation base rose like a rocket after they refind the Gastrea virus in their body. Most of the girls were promoted to Da Dou Shi, few were even promoted to Dou Ling on their first day of cultivation.
When the Gastrea virus in their body was eliminated the girl's face were filled with smiles. Xiao Feng, Kisara, and Koharu watched them smile, they also smiled.
For them to be able to become truly strong Xiao Feng always hunted Gastrea once in a while and brought it home as a cultivation resource. The girls were very happy to know, Xiao Feng hunted Gastrea for them. They were very happy about his care for them.
Xiao Feng personally supervised when Kisara absorbed the Gastrea blood for the fear of having an accident. In the end, everything went well and Kisara was promoted straight to 6-star dou zhe qi.
Even though Kisara was the weakest she was still happy for getting strong strength. Being happy and seeing that Xiao Feng was standing next to her to protect her, Kisara stood up and kissed him. After kissing she blushed and ran away.
...
Xiao Feng gave a lot of Gastrea blood to Seitenshi and supervised her when she absorbed the Gastrea blood. Seitenshi was happy that Xiao Feng cared about her. She took Xiao Feng to her room and started absorbing Gastrea's blood immediately.
Xiao Feng observed her the whole time for fear that she would have an accident. Thankfully, Seitenshi safely absorbed it and didn't have an accident. She was promoted to 5-star dou zhe qi after absorbing the Gastrea blood.
Seitenshi stood up, wrapped her hands around his neck, and kissed him deeply.
"Don't think too much this is your reward for taking care of me. I am still angry about your previous behavior."
Seitenshi pretended to be arrogant. Actually, she wasn't angry anymore, she was just upset about Xiao Feng killing so many people. With his constant care, her upset mood had become better. She didn't want to forgive him so easily, so she pretended to be arrogant.
Xiao Feng smiled slightly. He was relieved that their relationship was getting better and Seitenshi was not angry with him anymore.
"Since everything is done I am going back, Seitenshi. I will come back tomorrow." Xiao Feng jumped out of the window and went away.
"Xiao Feng, you are a piece of wood. Shouldn't you coax your girlfriend? Hmph! I will ignore you in the future." Seitenshi stomped her foot heavily on the ground when Xiao Feng disappeared.
...
Not only were they cultivating, Xiao Feng was also cultivating but what he cultivated was 'Chaos Grinding Thought Art'. In the 'Black Bullet' world except for the energy of stars, nothing could satisfy his need for cultivation so he could only practice the 'Chaos Grinding Thought Art' which didn't need much energy and could raise his soul level.
He killed too many people which led to him having a lot of resentment and murderous aura. He forged his body using them so that it wouldn't be able to interfere with his mind.
Even so few residues were left which were suppressed by his strong soul power.
...
In order to not make the girls a flower in the greenhouse. Xiao Feng let the girls fight against Gastrea to enrich their combat experience and be able to exert all their power brought by cultivation. He wanted them to get used to the sudden strength that they gained through their cultivation.
His plan was quite successful. All the girls quickly became used to their strength. They fought against the Gastrea bravely. The ground within a few-meter radius of every girl burst open and they fought against Gastrea head-to-head using their hands and feet.
Their combat experience became rich after fighting. He didn't have to be worried that they will suffer against someone in the future.
He let them fight against Gastrea while cultivating in the wild. It was to increase their wild survival instincts. While training them he continued to rescue cursed children all over the world. He also trained the girls who just came.
As for Koharu, Kisara, Tina, Midori, and Enju were trained by him specially. Everyone was quite envious at first but in the evening when they saw Koharu and others lying on the ground in the courtyard. They were panting heavily, their expression was very tired. They kept mumbling, "onii-chan no more! I can't do it anymore", "Xiao Feng, I can't do it", and "I quit". Looking at the miserable experience of the people lying on the ground they dismissed the idea of doing special training with Xiao Feng and quickly walked away.
Xiao Feng also trained Seitenshi in private. He took her to fight against Gastrea to enrich her combat. He taught her how to use her fighting skills. Every night they were together training until midnight. Now, Setenshi can fight against a stage 4 Gastrea easily.
Just like that everyone's training continued
...
Koharu was promoted to Dou Ling peak stage.
Kisara was promoted to Dou Shi peak stage.
Midori was promoted to 5-star Dou Ling
Tina was promoted to 7-star Dou Ling
Enju was promoted to Dou Ling peak.
Seitenshi was promoted to Dou Shi peak.
Rika was promoted to Dou Ling 6-stars
....
The result of everyone's cultivation was very good. Xiao Feng looked at the report about the cultivation of everyone, he was quite satisfied. During this year he trained them quite hard.
The cultivation base of Xiao Feng didn't change much during this year but his foundation became a lot firmer. His soul was at spirit grade early stage peak.
