Half a day later, inside the Seven Treasures Lustrous Glass Sect.
Chen Xin looked at the drastically transformed martial soul in his hand, his face expressing a mix of disbelief.
The once two-meter-long, half-foot-wide ancient giant sword had significantly shrunk, leaving only three feet and three inches of its blade, with a width of just over an inch.
The sword's color had shifted from its original clear blue to silver-white, and its appearance now seemed far less imposing than before.
But not only Chen Xin, even Gu Rong and Ning Fengzhi sitting beside him, vaguely felt a prickling sensation on their backs.
One could imagine just how sharp the Seven Kill Sword had become now.
In theory, with Chen Xin's expertise in swordsmanship and strength, it was impossible for such a murderous aura to emanate.
The only reason was the significant change in the Seven Kill Sword at this moment, which seemed to have surpassed his control.
The Seven Kill Sword was already a top-tier martial soul, and now it seemed to have gone even further. Chen Xin even felt that the current Seven Kill Sword had surpassed the Wu Tian Hammer, hailed as the strongest weapon type martial soul on the continent.
He felt like he was dreaming today.
After three years, his adopted son quietly returned to the sect after undergoing a transformation, revealing a martial soul longsword without any defects, and even comprehending the embryonic form of his own sword domain.
Then he brought out three bottles of attribute elixirs he had researched and prepared.
Based on his trust in his adopted son, he took them on the spot.
He never expected the effect to be so strong, directly causing a transformation in the martial soul Seven Kill Sword.
Beside him, Gu Rong and the sect master of the Seven Treasures Lustrous Glass Sect, Ning Fengzhi, also wore complex expressions.
Of course, it wasn't jealousy; their relationship was akin to family. It's just that everything that happened today was a bit beyond their understanding.
Even Ning Rongrong, who was only three years old, had a pensive expression, looking like a quiet little adult.
"It's truly unimaginable, you cowardly man, you sure have a good son," after a long while, Gu Rong finally breathed out and said what he had been wanting to say.
"If you keep blabbering, wanna go outside and have a little showdown?" Chen Xin retorted with a glare. Right now, he was itching to find someone to test the power of the Seven Kill Sword.
"You!" Gu Rong's face changed, feeling a drumbeat in his heart, but he couldn't back down, "Come on then, let's compare."
Seeing this, Ning Fengzhi quickly smiled bitterly and intervened, "Uncle Sword, Uncle Bone, now is not the time for you two to bicker."
Then he turned to Chen Xin and asked seriously, "Brother Sword, how do you see the matter that Su Cheng just mentioned?"
Seeing that he was asking about serious matters, Sword and Bone finally calmed down.
After a moment of silence, Chen Xin spoke firmly, "My son's affairs are naturally my affairs."
His tone was resolute, showing that he had made up his mind.
At this moment, a fairy grass was lying quietly in his soul tool.
In his ears echoed the conversation between him and Su Cheng just before he left.
"Father, after you completely control the transformed Seven Kill Sword martial soul, you can take this fairy-grade spiritual grass, Golden Silk Crystal Sword Grass. With the help of the fairy grass, you will have more than enough strength to reach level 97 within ten years, and even have a chance to glimpse the scenery of level 98. But that will require some luck, so don't force it."
"Cheng'er, are you going back to the Martial Soul Hall?"
"Of course, I have to go back. Ten years later will be the day of the Martial Soul Hall's destruction, and I hope Father can help me then."
At that time, Chen Xin didn't understand his son's choice.
"Why risk going back to the Martial Soul Hall when you've reached this level of research? Why not focus on improving your strength and becoming the strongest? I had doubts before, but now I believe you can definitely do it."
"I can't do it, and there's no time left."
Chen Xin didn't understand what Su Cheng meant by not having time, but he knew his adopted son had always been very determined. Besides, with his current abilities, he had completely surpassed his own understanding, so he couldn't control him anymore.
And from what he described, Chen Xin also knew that Su Cheng's status in the Martial Soul Hall was extremely high now, indicating there were other secrets involved.
Thinking of this, Chen Xin's face showed a sense of melancholy.
Even if he could reach level 98, what could he do when facing the Martial Soul Hall?
The Grand Elder there was a level 99 Ultimate Douluo.
Meanwhile, Ning Fengzhi nodded on the other side, without intervening.
Just now, Su Cheng also gave him a promise, saying he would try his best to help him increase the upper limit of the Seven Treasures Lustrous Glass Tower's martial soul.
If he didn't believe the other party could do it at first, seeing the transformation of the Seven Kill Sword now, he had no choice but to believe.
...
At this moment, Su Cheng was already on his way to the city of Nuoding.
He had other things to arrange and didn't have much time to linger in the Seven Treasures Lustrous Glass Sect for reunion.
Thinking back to the scene just now, he couldn't help but sigh inwardly.
He didn't expect today to be so unfortunate, to actually run into those few people gathering together.
Originally, he had planned to only meet Chen Xin alone.
To prevent Ning Fengzhi from interfering, he had no choice but to first make a promise. It seemed tempting enough to improve the upper limit of the Seven Treasures Lustrous Glass Tower's martial soul.
And luckily, the attribute elixirs were powerful enough; he reckoned that guy must have been tempted.
Chen Xin was different from Su Cheng.
With the strength of a Titled Douluo, after taking the elixir, it wouldn't take long for him to fully digest it.
Although the benefits weren't as great as when taken in childhood, the effects were immediate.
In fact, for Su Cheng, giving Chen Xin the attribute elixir was just an experiment. He wanted to see how strong the ultimate path of the sword martial soul could be, and which way was better compared to completing the five elements.
The key was still the fairy grass he gave to Chen Xin, after all, it was the only top-tier combat power he could fully trust.
After years of being together, he had deep feelings for this adoptive father.
However, he wasn't prepared to let Chen Xin take risks when the time came.
Gathering his thoughts, Su Cheng gazed into the distance towards the city of Nuoding.
"Yu Xiaogang, Tang Hao, Tang San...…."
He still had several other things to do next.
Once everything was completed, he could return to the Spirit Hall City and wait for the final battle.
...
During the month Su Cheng was away, Qianren Xue found that his cultivation efficiency had drastically dropped.
Although under Su Cheng's guidance, she had already developed excellent thinking and cultivation habits, but now she always felt unable to calm down.
It was the first time she felt like this from childhood to adulthood.
Her parents rarely paid attention to her when she was young, and she never developed any dependency on anyone.
As for Bibi Dong, needless to say, although she was kind to her, as the Pope, she was busy with affairs, and her arrogant and self-righteous character didn't qualify her as a good mother.
To gain her mother's approval and not disappoint her grandfather, Qianren Xue basically relied on her own abilities to solve problems.
Everything changed after she got Su Cheng as her teacher.
She hadn't realized it before, but recently, this feeling had become clearer.
Sitting on the chair in Su Cheng's room where he often sat, Qianren Xue casually flipped through the books on the table.
She was very familiar with this room. Many of the books placed here were related to her recent cultivation direction, such as "Detailed Explanation of External Attached Spirit Bone Characteristics," "Spirit Bones and Martial Souls," "Tool Martial Souls and Beast Martial Souls," and so on.
