I Have Medicine

Chapter 581 - (Contract Upgrade) Fourth Tier

Gu Zuo was completely dumbfounded.

His Divine Core was a wheel. His big brother’s mind now had the image of a wheel in it. His big brother had six qi seas, and now his mind also had six shadow-like qi seas… So did that mean they were directly projecting into each other’s minds?

There was no way this had nothing to do with what happened last night—he wasn’t buying that for a second!

—Not that Gu Zuo could be blamed for being so worked up. After all, he had been confused from beginning to end.

All that had happened was… well, somehow, this time, he failed to resist the temptation of his big brother’s beauty and ended up making a move. And that move, rather smoothly, succeeded.

Wait. No. Hold on.

Maybe… maybe it wasn’t just “somehow.”

After activating his Divine Eye, Gu Zuo noticed not only had it been further tempered, but the power within had changed too. It was no longer the faint blue typical of the Duo Mu Tribe, nor the blue of the Blue-Eyed Tribe—it had become a silver-white power, the same color as his Divine Spirit!

What’s more, although the silver hue still held a strange and mysterious energy, it now flowed much more smoothly than before. The heavy, burdensome feeling he once sensed in it had completely disappeared, as though it had all been released for some reason.

Yes—released.

Gu Zuo couldn’t help but think back to the events of the night before.

He thought about it for a long time, and finally started to piece things together.

Perhaps his so-called “refinement” process had never actually been complete.

The Divine Eyes of the Duo Mu Tribe could remain active and even enhance the Blue-Eyed Tribe’s abilities—this surely meant that a trace of consciousness remained within them. And the Blue-Eyed Tribe’s blue pupils must also carry some traces of their own awareness.

So after Gu Zuo refined these conscious fragments, those bits of “mind” didn’t just vanish. They were ingrained and stubborn, not so easily erased.

Still, without something to cling to, a piece of disembodied consciousness was like water without a source—what remained was merely a pure sliver of obsession. If those obsessions had all shared the same focus, they might have seriously impacted Gu Zuo’s thoughts. But since each obsession came from a different person, they cancelled each other out… leaving only the one thing they all managed to stir in Gu Zuo: the most secretive, most embarrassing thought buried deep in his heart, blown up tenfold.

And conveniently… Gu Zuo, in the full bloom of youth, didn’t have many unfulfilled desires. Nor had he done anything that weighed on his conscience. His life was smooth and satisfying. The only thing that brought him the slightest bit of inner turmoil… was the fact that he was occasionally overwhelmed by his big brother’s beauty and had to forcibly calm himself by making pills to suppress those thoughts.

Well, now? No need to suppress anything.

Gu Zuo had gone and done exactly what the deepest part of him had wanted all along—he’d flirted with his big brother. And he’d succeeded. Physically and emotionally, they’d taken a major step forward.

You could say that if before, it was like they were engaged—now, aside from the lack of a formal ceremony, the two of them had practically married and even spent their wedding night.

Once Gu Zuo realized all this, his expression turned a little… complicated.

He didn’t know whether to be upset about his behavior last night, or relieved that the thing he’d considered his deepest, most shameful regret… had turned out to be this.

Thankfully, now that the night had passed, that lingering consciousness had vanished completely—leaving only two people who had fully given themselves to each other, physically and emotionally, as true soulmates.

After Gu Zuo figured things out, he told his big brother everything about his current situation. A little embarrassed, he said, “I really never expected any of this…”

Hearing this, Gongyi Tianheng also found it quite strange.

He had never heard of anything like this happening before, yet it had happened to the two of them. Just moments ago, he’d also examined that massive wheel-shaped projection. He found that it seemed vaguely connected to his own mind, and on that giant wheel was a powerful, irresistible pull—like it was trying to draw in his six qi seas and embed them into its rotation. And the power being brewed through that rotation… was incredibly terrifying. It actually felt stronger than the combined force of all six of his qi seas!

It was almost as if… his and Ah Zuo’s powers were being fused together.

After pondering briefly, Gongyi Tianheng said, “Why don’t we ask Ling Su?”

Gu Zuo froze, then came to his senses and gave a slightly bitter smile. “Right… I could’ve asked Ling Su.”

Ever since the last time he refined the Medicine Hall and Ling Su acknowledged him as her master, the Ling Su who was like a system—akin to a machine—gave him a completely different feeling from the real, flesh-and-blood Ling Su. Besides, Ling Su had always preferred Tianyou as her master. While Gu Zuo was happy that Tianyou had such a strong supporter, he couldn’t help but feel some distance from her. As a result, he didn’t quite trust her fully and often avoided relying on her for anything.

Even before this, he rarely consulted the system. Now that the system had taken the form of Ling Su, he depended on her even less and never thought to seek her out… which is why it hadn’t even crossed his mind to ask her.

Still, both Gu Zuo and Gongyi Tianheng now had the same suspicion—

The changes in the two of them might very well be closely tied to their Guardian Contract.

Soon, the two were about to enter the Medicine Hall.

Suddenly, Gongyi Tianheng placed a hand on Gu Zuo’s shoulder and said, “Wait a moment.”

Gu Zuo looked puzzled. “Big brother?”

Tianheng gave him a quick once-over, then took out a robe and gently draped it over him. “Ah Zuo, don’t catch a cold.”

Gu Zuo’s face immediately went bright red.

He just realized—after last night, he was still naked! Only the blanket had covered half of his body. Which meant he had been talking with his big brother and focusing on sensing the Celestial Palace while completely unclothed!

He wished so badly this had never happened… No, he really regretted not putting clothes on earlier!

Embarrassed beyond belief, Gu Zuo hurried to put on the robe. There was no describing the sheer awkwardness in his heart.

Thankfully, his big brother had reminded him. Otherwise, if he had walked into the Medicine Hall naked and been seen by Ling Su… that would’ve been beyond mortifying.

—And how could Gongyi Tianheng possibly let the person he had just shared such deep intimacy with go meet another woman looking like that?

Gu Zuo took a deep breath and quickly finished dressing, then hopped off the bed.

Now that he was properly clothed, his mood finally settled.

He exchanged a look with Gongyi Tianheng, and together, they stepped into the Medicine Hall.

As expected, they found Ling Su in a smaller hall at the back.

Ling Su sat cross-legged on a cushion, her expression serene and composed, exuding a calm and dignified presence.

When Gu Zuo entered, she rose to her feet and bowed. “Master.”

Gu Zuo waved his hand and also sat down. “No need for formalities. I came here with my big brother because there’s something we want to ask you.”

Ling Su nodded silently. “Please, Master, go ahead.”

Now that Ling Su had regained a human form, she no longer requested medicinal energy from Gu Zuo. Naturally, when Gu Zuo asked questions, she no longer spoke of any kind of exchange like “a certain amount of medicinal energy per answer.”

After a moment of thought, Gu Zuo left out any mention of what had happened between him and his big brother the night before. Instead, he asked, “Ling Su, my big brother and I discovered that within each other’s dantian, we can see reflections of the other’s inner phenomena. My divine spirit broke free and projected itself in his space, and his six qi seas are mirrored in mine. What’s going on?”

Ling Su replied with understanding, “Congratulations, Master, on your joyous marriage.”

Gu Zuo: “……”

She figured it out just like that?!

Ling Su continued, “This matter is related to the Guardian Contract. Since this contract was passed down from the former master, it is no ordinary agreement—it is one that has existed since ancient times, aligned with the very rules of heaven and earth. Once the contract is signed, no loopholes remain; neither party can ever cause harm to the other. And with each upgrade of the contract, both parties receive tremendous benefits.

You and Young Master Gongyi should already be aware of the benefits from the first three levels. If the bond between two people is only that of life-and-death comrades, the contract can reach up to the third tier at most. But if the bond between them deepens emotionally and becomes truly integrated, then their internal energies begin to intermingle. At that point, and only under the contract’s influence, can they reach the state of ‘shared life’—which is the fourth tier.”
