At four in the morning, leaving Koneko and Kuroka to catch up on sleep, Tatsuma came to the fourth basement level.
Unlike the training ground on the third basement level, the fourth basement level was divided into several different areas.
Tatsuma walked into the material room on the right and took off the red bracelet on his right hand.
This bracelet was a weighted equipment he had asked Rias to get from the Underworld not long ago, capable of enabling up to a hundred times the gravity.
When he first got it, Tatsuma only dared to activate twenty to thirty times the gravity for training.
But as time went on, his physical stats improved through repeated training.
In addition, among the traits that increased training efficiency, there were also many that increased physical stats and recovery ability.
By now, a hundred times the gravity was no longer the limit for Tatsuma.
In order to become stronger faster, he decided to personally modify the equipment.
Wearing a set of scientific research traits led by a scientific research expert, Tatsuma opened his storage space and took out a dragon skin.
The dragon skin was obtained by him at MAR. Unlike native dragons like Ddraig, this dragon skin came from a dragon from another world.
Tatsuma was not clear about the specific situation, but after appraisal, it was confirmed that this dragon skin had high magic affinity.
Manually cutting off a piece of dragon skin, Tatsuma began to engrave runes on the dragon skin.
After a moment's work, Tatsuma had left five different runes on the dragon skin.
Mobilizing demonic power, he activated it.
As the runes lit up, the dragon skin slowly extended and covered the surface of the bracelet, connecting head to tail and merging into one.
"Not bad, it succeeded on the first try."
Looking at the bracelet with dragon patterns appearing on its surface, Tatsuma put it back on his wrist and tested the effect.
After the modification, the bracelet could now enable up to one thousand times the gravity, ten times the original limit.
Coming to the training ground and activating two hundred times the gravity, Tatsuma adapted for a while and then began training.
100 push-ups, 100 sit-ups, 100 squats, and a 10-kilometer long run to finish.
It was still the same unchanging training method. However, under the high pressure of two hundred times the gravity, Tatsuma could clearly feel that all parts of his body were being trained.
Time passed, and three hours went by.
Tatsuma, like an emotionless robot, continuously carried out round after round of training.
Sweat dripped from his forehead, and he could vaguely feel that he was getting closer and closer to the next level.
But just then, a ding sound rang out.
Tatsuma exhaled deeply and stopped training, picking up the phone placed next to him.
"Hello, is there something you need?"
"The secretary you mentioned yesterday, I've already found her for you." Sirzechs's voice rang out.
Tatsuma was surprised. "That fast?"
"The other party is interested in you, we basically didn't have to put in much effort to reach an agreement."
Tatsuma asked, "Who is the new secretary?"
Sirzechs said, "Ravel Phenex."
"You're quite good at finding people, didn't her clan say anything?"
"Being able to befriend the famous Red Dragon Emperor, I don't think anyone would refuse."
Tatsuma asked, "That's good, when can she report to me?"
Sirzechs replied, "Tonight."
"I understand, just have her come to Kuoh Town to see me then."
After that, Tatsuma chatted with Sirzechs about MAR and the Three Factions' cooperation.
After settling some details, Sirzechs coughed, and his voice became serious. "Tatsuma, I just received some information from Soul Society."
Tatsuma asked, "Something happened to Rukia?"
Sirzechs was stunned. "How did you know?"
"I guessed."
"...Did you intentionally let Rukia go back to Soul Society?"
Tatsuma answered, "Kind of, but I only knew that Rukia going back would make Aizen and the others act, I wasn't sure what exactly would happen. Tell me about it, what's the situation now?"
Sirzechs said, "The Central 46 were wiped out, and Rukia was captured."
Taking a few minutes, Sirzechs repeated the information he had just received.
"Tatsuma, the situation inside Soul Society is very chaotic now."
"However, Ukitake and the others hope that you won't go to rescue Rukia for now."
"Okay."
"I know this matter... Huh? You agreed?"
"Otherwise? Do you want me to go to Soul Society now, kill my way through the Gotei 13, and solve Aizen along the way?"
"No, no, no, you absolutely must not do that." Sirzechs quickly stopped him.
Ravel's matter was just a side note for this morning call. The real purpose was to persuade Tatsuma to remain calm and not act rashly.
Since Tatsuma was willing to cooperate, that was naturally the best outcome.
However...
"Tatsuma, what are you calculating?"
"I'm not calculating anything, I'm just cooperating with your actions."
Sirzechs was confused. "Cooperate with our actions?"
Tatsuma said, "What I mean is, I don't need to rack my brain thinking about those troublesome issues."
"To allow me to play my full role, both you and Aizen will prepare the battlefield for me."
"And all I need to do is use my fists to deal with the enemies blocking my path, that's all."
"...That really is a statement in line with your style."
Sirzechs fell silent for a moment, a relieved smile appearing on his face.
"Since you've said that, then continue to work hard and become stronger. When I need you to make a move, I will contact you proactively."
"Pleasant cooperation."
Tatsuma chuckled lightly and hung up the call.
Leaving the training ground and returning upstairs, he found that Rias and the others had all woken up.
Today was Monday, and after eating breakfast together, everyone went to school as a group.
"Hmm?"
As soon as he stepped into the school, a familiar yet unfamiliar figure appeared in Tatsuma's line of sight.
"Is that person... Issei?"
Rias also noticed the other party, a flicker of surprise flashing in her eyes.
Asia asked curiously, "Who is Issei?"
Rias replied casually, "A previous client. He was attacked by a Fallen Angel and severely injured, and only survived with Tatsuma's help."
Her gaze turned towards Tatsuma, who had stopped beside her. "Is there something wrong with him?"
"There's nothing wrong, I just suddenly thought of something."
Tatsuma told Rias and the others to go to class first, while he walked over and called out to Issei.
"Morning, Tatsuma." Issei greeted him warmly.
Because his life had been saved, his relationship with Tatsuma was quite good.
"You're the same as always today, surrounded by a bunch of beauties, I'm so jealous."
Tatsuma said, "No need to be jealous. If you add up all those discs under your bed, the number is more than my girlfriends."
"???"
Issei's eye twitched, feeling as if he had been punched and couldn't fight back.
"You didn't come running here early in the morning just to say that, did you?"
Tatsuma took out a bank card and said, "No, I just saw you and suddenly remembered something. There's a total of 10 million yen in here. How about we have a fight?"
"Ah?"
Issei was stunned.
To be honest, he wasn't unfamiliar with this matter.
The first time he met Tatsuma more than two months ago, the other party had done something similar. But what he didn't understand was why Tatsuma, a Devil whose strength was terrifying, kept wanting to fight him.
"What do you say? Want to earn this extra cash?" Tatsuma's voice sounded again.
Issei came back to his senses and quickly nodded his head in agreement.
Although getting beaten wasn't a good thing, Tatsuma was giving too much. Under the condition of safety, Issei didn't mind being a human sandbag a few more times.
"Contract established. Take the money and come with me."
Handing the bank card to Issei, Tatsuma took him to the small grove behind the teaching building.
One minute later.
[Congratulations on successfully defeating Issei Hyoudou and obtaining the red trait: Oppai Star.]
[Oppai Star (Red): Greatly increases the love for Oppai, can sense the existence of Oppai Power and absorb and control it.]
(Note: Oppai = Boobs)
As expected of the protagonist, the drop rate is high.
Looking at the newly acquired red trait before him, Tatsuma's gaze towards Issei became softer.
Including the Boosted Gear, this was already the fourth trait he had gotten from Issei.
One gold, three red.
There was a different surprise every time.
Issei, who had just crawled up from the ground, shivered. "Uh... why do I feel your gaze suddenly became dangerous?"
"Your illusion."
Tatsuma took a blank nameplate from his pocket and threw it over. "Take this, it can save your life if you encounter danger."
Issei was stunned. "This should be very precious, why are you suddenly giving me this?"
Tatsuma said, "Things are going to get chaotic, this is to prevent you from suddenly dying if you encounter danger."
Quality clients like Issei, who could be repeatedly beaten and constantly drop new traits, were not many.
