Creative Uses of Soul Skills

Almost at the same time, both Qian Renxue and Su Yu let out a sigh of relief.

Su Yu grumbled inwardly, She kept her secret, and I kept my life. Everyone has a bright future!

Then, Su Yu explained, "If we establish rules like this, it becomes an alternative lie detector."

"However, this kind of lie detector still has loopholes. It can only prevent subjective lies."

Seeing Qian Renxue's puzzled expression, Su Yu thought for a moment before saying, "For example, someone might awaken Twin Martial Souls but never tell anyone else. If we captured that person's family or friends and questioned them this way, we still wouldn't get the truth."

"Because, as far as they know, that person really only has one martial soul."

Qian Renxue nodded thoughtfully, signaling Su Yu to continue.

"But I can make a slight adjustment to the rules."

As soon as he finished speaking, light appeared on the pages of the Brass Book once more, forming new words.

[2. Breach of contract!]

Pointing at the second rule, Su Yu said, "As I mentioned before, the rules established by the Brass Book must conform to common understanding and receive a certain degree of recognition."

"Being punished for breaching a contract is perfectly reasonable."

"But we can freely invent the specific terms of the contract."

"That gives us room to operate."

Upon hearing this, Qian Renxue's eyes lit up, and a vague idea formed in her mind.

Su Yu did not wait for Qian Renxue's thoughts to take shape. Instead, he directly took out paper and a pen from his storage Soul Tool and wrote—

[Party A shall pay Party B one Gold Soul Coin;]

[Party B shall provide Party A with medicine capable of increasing the soul ring absorption limit.]

[Party A:][Party B:]

Just like that, an utterly unreasonable contract with clearly defined responsibilities for both parties was born.

"If the medicine delivered by Party B fails to achieve that purpose, the Brass Book will automatically make a judgment and carry out Punishment."

Facing Qian Renxue's look as though she were staring at a devil, Su Yu said, "This way, we can begin trial and error, gradually exploring what can improve a Soul Master's physical constitution and allow them to break through their soul ring absorption limit... It's just a little costly in manpower."

"And you call that 'a little'?" Qian Renxue looked indignant. "How much time will this take?"

Su Yu shook his head. "The contract says Party B must deliver this kind of medicine, but it never says Party B can only deliver this kind of medicine."

"We can go to the largest pharmacies, buy every medicinal ingredient, divide them into two portions, and hand one portion to Party A."

"That way, we can eliminate half the wrong options at once. By repeating the process, we'll reach a conclusion very quickly."

Qian Renxue considered it and felt that Su Yu's reasoning truly made sense. Then she sighed, "I really don't know how your brain works. A martial soul can actually be used like this..."

Su Yu merely spread his hands and said nothing more.

Qian Renxue gave Su Yu a deep look, then called out, "Someone! Go to Ye Family Pharmacy, Seven Treasure Pharmacy, and several other major pharmacies. Buy one of every medicinal ingredient they have!"

It had to be said that the guards of the Crown Prince's Residence were highly efficient. In less than two hours, all manner of medicinal ingredients had been packed into storage Soul Tools and placed before Qian Renxue and Su Yu.

At that moment, Chi Xue stood before them with a grief-stricken expression and signed his name in Party B's space.

As for the candidate for Party A—

Although Qian Renxue was quite interested, considering that she was only playing the role of Xue Qinghe, she could only give the opportunity to Su Yu.

Of course, in Su Yu's opinion, Qian Renxue was simply overthinking it.

She had played Xue Qinghe for so many years that she had long since developed a sufficiently close connection to that name.

After both parties finished signing, Su Yu took out a Gold Soul Coin and handed it to Chi Xue.

After receiving the Gold Soul Coin, Chi Xue released his Soul Power from his body, forming a spherical barrier without blind spots. Then he handed Su Yu a ring-shaped storage Soul Tool.

Smack! Smack! Smack!

Chi Xue slowly let out a breath. Thankfully, he had prepared his defenses in advance. Otherwise, even if a whipping did not cause much damage, the humiliation would have been immense!

Then, Chi Xue took out another ring and exchanged it with Su Yu for another Gold Soul Coin.

This time, however, the invisible whipping did not descend.

Chi Xue and Qian Renxue's eyes lit up. This meant that the second batch of medicinal ingredients truly contained something capable of helping Soul Masters break through their soul ring absorption limit!

Su Yu handed the second ring to Chi Xue. Once he watched him divide the medicinal ingredients inside into two portions, he handed over another Gold Soul Coin.

When Su Yu received the ring, there came a sharp whoosh, as though a blade had sliced through the air and struck Chi Xue's Soul Power barrier. Yet it vanished into the barrier like mud sinking into the sea, without causing the slightest ripple.

Chi Xue's mouth twitched. "It was Whipping before. How did it suddenly upgrade to getting chopped by a blade? Didn't you say the punishment would gradually increase in severity? How did it jump straight to the death penalty?"

Su Yu rubbed his chin. "The target probably wasn't a vital spot. It was only meant to injure the violator, not kill him... How powerful was that attack?"

Chi Xue thought for a moment before commenting, "Even the second soul skill of a defense-type Soul Grandmaster should be able to break through it."

Su Yu was very satisfied with that answer.

Afterward, the two continuously repeated the earlier process, while the shock in Chi Xue's eyes grew increasingly intense.

In the end, after more than a dozen experiments, Su Yu looked at the Whale Rubber in his hand with delight.

"Brother Xue, it seems this is the medicinal ingredient that can increase a Soul Master's soul ring absorption limit."

Qian Renxue's mouth twitched as she slowly said, "Xiao Yu, are you sure?"

Pretending to be confused, Su Yu asked, "Brother Xue, didn't you watch the entire selection process just now?"

Seeing Qian Renxue's withdrawn expression, Su Yu said, "Brother Xue, perhaps this thing has other medicinal effects and is therefore used elsewhere."

"However, medicinal ingredients can display all sorts of different effects through different processing methods."

"Just like my soul skill—so long as one's ideas are flexible enough, all kinds of unexpected applications are possible."

"As for medicinal ingredients, it's nothing more than brewing them into soup or roasting them directly over a fire... As for how to determine which treatment method is correct..."

With that, Su Yu looked toward Chi Xue again and revealed an ill-intentioned smile.

Chi Xue closed his eyes, hoping that everything before him was merely an illusion.

Then, Su Yu wrote a new contract.

Having fully resigned himself to being a tool, Chi Xue signed his name on the contract and began a new round of experiments.

After another round of trouble, the three finally confirmed that if Whale Rubber was roasted over a flame until it softened and gave off a strange fragrance, then swallowed directly, it could increase a Soul Master's soul ring absorption limit!
