He cultivated himself into a Dao Ancestor starting from Qi Refining.

The "Self-Severance Technique" is a special secret technique that Lin Shaoyu discovered after killing Lu Jinghong, seizing his storage bag, and finding it inside.

Moreover, Lu Jinghong was an outer disciple of the Yuanshi Immortal Sect, with a good background and origin, so his storage bag contained many good things. However, Lin Shaoyu had been busy traveling around and did not have the time or energy to sort them out carefully. But this "self-severing technique" attracted a lot of attention from Lin Shaoyu.

Because the "self-severing method" is not a supernatural power, nor a true skill, nor a magic technique, but an extremely special secret method within the Qi Refining Realm.

The only effect of the "Self-Severing Technique" is that after mastering it, one can sever one's own supernatural powers and true skills, cutting off the true skills and supernatural powers that have been cultivated from oneself.

Take Su Ya and Zhang Qianmian for example. They mastered twelve true skills, but they couldn't combine them to cultivate supernatural powers. However, they could use the "self-severing method" to sever the true skills they had already mastered and start cultivating other true skills.

The same applies to "supernatural powers".

"The 'self-mutilation method' is incomplete."

Lin Shaoyu observed Zhang Qianmian and Su Ya practicing the "Self-Severing Technique" and the process of their self-severing, and then he noticed something was wrong. After the "Self-Severing Technique" severed their true power, the "True Qi" they had cultivated dissipated into the world on its own. "There must be an extremely crucial part left."

Therefore, Lin Shaoyu used the power of the He Shi Bi jade and tried to understand the self-inflicted injury technique, but the feedback he received shocked him greatly.

It actually requires a green destiny number.

"!!!"

Shock!

That's truly shocking!

When Lin Shaoyu was spying on Fu Hongxu, he needed to consume an orange life force because it involved a supreme supernatural being.

However, now, to even glimpse the "Self-Severance Technique" requires one green life point, and one green life point is equal to ten yellow life points, which in turn equals one hundred orange life points.

"Foundation Building!"

Lin Shaoyu immediately realized what was happening, and the words "Foundation Building" popped into his mind. "The 'Self-Severing Technique' probably involves the true 'Great Secret of Foundation Building,' which is why it requires such a terrifying amount of life force to glimpse it. Otherwise, it would be impossible to require a green life force. This is simply too exaggerated."

Zhang Qianmian and Su Yaxiu mastered the "Self-Severance Method" and also conducted experiments on Lin Shaoyu to confirm its feasibility.

However, it has side effects.

That means it will reduce the success rate of Foundation Establishment. Every time a cultivator in the Qi Refining Realm makes a self-inflicted cut, the success rate of Foundation Establishment will decrease by 10%.

Time flies, and three days have passed in the blink of an eye.

Inside the secluded room.

"The substitute doll! Done!"

Lin Shaoyu formed hand seals, and the Divine Power True Seal of the Substitute Man erupted with extremely brilliant light, splitting into three streams of Dharma light, which condensed into a special Dharma seal and merged into the bodies of Du Min and the other two.

Boom! Boom! Boom!

Du Min and the other two were shaken, their auras rising. Du Min broke through to the fourth level of Qi Refining, while Zhang Qianmian and Su Ya both recovered to the twelfth level of Qi Refining.

The moment the 'Substitute Doll' was completed, Lin Shaoyu felt a connection in the darkness, sensing the appearance of a 'Substitute Thread' originating from the 'Divine Power True Seal' of Lin Shaoyu's substitute doll, which then landed on Du Min and the other two, forming an unbreakable link.

In this way, Lin Shaoyu completely controlled everything about Du Min and the other two, and held their fates in his hands. If Lin Shaoyu so desired, he could even travel thousands of miles, directly descending upon them with his consciousness and taking over their bodies, or he could inflict all the suffering he had endured upon them, making Du Min and the others bear it.

"good!"

Lin Shaoyu smiled, extremely satisfied. "This is the 'Substitute Puppet.' Even with the limit of the 'Substitute Person,' it can only withstand nine Substitute Puppets. However, after a Substitute Puppet perishes, it can be re-cultivated and refined."

"My lord!"

"..."

Du Min and the other two had already woken up. After stabilizing their breathing and cultivation, they knelt down together in front of Lin Shaoyu, bowing and paying their respects with the utmost deference.

"well!"

Lin Shaoyu's lips curled up in a smile, overjoyed.

"My lord!"

Du Min then raised his head and kowtowed repeatedly to Lin Shaoyu. "I have something to report to you. In fact, besides the incomplete 'Minor Divine Power Technique: Qimen Dunjia', I also possess the inheritance of three other minor divine power techniques, and these three inheritances are the foundation of the Blood Demon Body Refining Sect."

"Um?"

Lin Shaoyu's gaze fell on Du Min. "So you lied to me before."

"Forgive me, Lord!"

Du Min's tone was fearful, "I did conceal some things before, and didn't tell you everything, but... I..."

Rumble!!!

Just then, a huge explosion rang out from outside, and could even be heard inside the secluded cultivation room. It was the Yue Kingdom's army and cultivators launching a forced attack on the city, and the Protectorate City could not hold out for much longer.

Three days later, yesterday morning, the Yue army broke through the defensive formation of the city and was about to enter the city.

It was precisely because of the intervention of Ling Qingxiao and Ye Shuanghua, two outer disciples of the Yuanshi Immortal Sect, that the city's protective formation was able to be breached in such a short time.

The commander of this army was none other than Hua Tianqi, the Prince of Zhennan of Yue.

Hua Tianqi was furious because Hua Qingfeng had disappeared. He eventually learned that Hua Qingfeng was dead, the clan's soul lamp had been extinguished, and even the body could not be found.

The pain of losing his son enraged Hua Tianqi to the extreme, and he led the Yue army in a frenzied attack on the city. The city guarding the capital could no longer hold out and was likely to be completely captured today.

"this……"

"The Yue army is attacking the city again."

Zhang Qianmian and Su Ya's expressions also changed drastically.

"My lord."

Du Min swiftly produced nine jade slips, each containing a recorded skill. Prostrate himself on the ground and quickly said, "These are the three minor supernatural abilities. Please forgive me, Master!"

In fact, Du Min was not truly submissive from the beginning; he had his own calculations and plans.

He was a direct disciple of the Blood Demon Body Refining Sect and was personally hunted down by the Prince of Zhennan. Naturally, he possessed the true inheritance of the Blood Demon Body Refining Sect.

Lin Shaoyu had naturally seen through it long ago, but he was not in a hurry. He knew very well how terrifying and unpredictable the "substitute" was. Once Du Min became his "substitute puppet," he would naturally confess everything and hand over the entire inheritance of the Blood Demon Body Refining Sect.

There is absolutely no need to force them anymore.

"Du Min, considering your timely repentance and the fact that you produced the Blood Demon Body Refining Sect's inheritance, I will not pursue this matter further this time."

Lin Shaoyu waved his right hand and took the nine jade slips in his hand. He then instructed, "The situation in Protectorate City is not optimistic. It won't last long. You will immediately join the battle and assist Protectorate City in defending the city."

"yes!"

"Yes, sir!"

"Thank you for your forgiveness, Lord!"

Du Min and the other two responded quickly and immediately stood up, transforming into three streaks of light. They escaped from the secluded training room and headed to the battlefield to defend the city.

"The legacy of the Blood Demon Body Refining Sect."

Lin Shaoyu took out the nine jade slips he had just acquired and probed them with his divine sense. "I can't cultivate the Qimen Dunjia for the time being. I hope the power of the Blood Demon Body Refining Sect's inheritance will not disappoint me."

The nine jade slips of inheritance in his hand were activated as Lin Shaoyu probed them with his divine sense, and a large amount of information and true skills were poured into Lin Shaoyu's mind, which he quickly understood and memorized.

On the other side...

On the battlefield outside.

Hundreds of thousands of troops clashed in a full-scale battle, their terrifying killing intent soaring into the sky. Cultivators were also fighting and battling in the air. The protective formation of the royal city had been breached, and the situation was extremely critical.

People die on the battlefield every moment.
