Super Island Tycoon

This kind of question naturally made the two sisters quite shy. Guan Xiaofei was relatively okay, but Su Qianqian blushed deeply and buried her face in Jiang Cheng's chest.

Jiang Cheng didn't hesitate and continued on... This time, Jiang Cheng lasted a very long time. If before, Jiang Cheng was still somewhat young, so his stamina was decent, now, Jiang Cheng purely became much stronger. He not only completely satisfied the two girls, but also thoroughly conquered them, more than once.

Even so, he still felt he had much strength left—even if he kept going, it would be no problem at all.

However, Jiang Cheng didn't pursue that aspect further, just lay on the couch, holding these two warm and soft bodies, enjoying this brief tenderness. The feeling was quite nice.

In his past life, Jiang Cheng had always been devoted to research, dedicating all his time and energy to scientific endeavors, with no time to invest in emotions. On reflection, although he achieved countless accomplishments, more often he felt a sense of emptiness.

After all, no matter how brilliant he was, he was only human. Having someone to keep by his side was quite important.

"By the way, didn't you guys just feel like I changed but didn't know why I changed all of a sudden?" Jiang Cheng suddenly spoke up as if thinking of something.

"Hmm?" Guan Xiaofei paused for a moment, then nodded and asked, "Does it have anything to do with the results of Jiang Cheng's closed-door research this time?"

"What kind of research results this time?" Su Qianqian asked, a bit curious.

Jiang Cheng smiled but didn't say much. Instead, he picked up a one-yuan coin from beside him and said, "Watch carefully."

It was a very ordinary coin. The two girls stared at it for quite a while, finding nothing strange about it. They were a bit confused about what Jiang Cheng intended to do with it.

"Huh?"

Under the curious gazes of the two girls, Jiang Cheng effortlessly bent the one-yuan coin and then rubbed it into a small ball.

"What, what, what??" The two girls watched this scene and for a moment couldn't believe their eyes, exclaiming in shock, "What... is going on here..."

"Magic?" Su Qianqian instinctively asked.

"Not magic, it's just an ordinary coin." Jiang Cheng showed the small ball-shaped coin to the two girls, "Three-seven-zero."

Su Qianqian and Guan Xiaofei examined and touched it carefully to find it was indeed a regular one-yuan coin, very solid, not a magic prop meant to look hard but be soft.

"So what is going on?" Guan Xiaofei was still a bit confused and completely clueless about the situation.

"Has Jiang Cheng's strength suddenly become so great? And I felt that when Jiang Cheng was doing it just now... he seemed... more powerful than before." Although Su Qianqian spoke infrequently, she was quite perceptive. Instantly sensing something, her thoughts wandered back to the earlier encounter, making her cheeks redden again as she said softly.

"...It's indeed like that." Guan Xiaofei nodded in agreement, then looked at Jiang Cheng, who was still being mysterious. She couldn't help but feel anxious, her curiosity peaked, eagerly asking, "What's going on, hubby~~ tell me, don't just stoke our curiosity and leave us hanging."

"Do these changes have anything to do with the research results this time?" Su Qianqian asked softly from the side.

"Yes." Jiang Cheng nodded and stopped being mysterious as he said, "I've researched and developed the Genetic Evolution Potion."

"Genetic Evolution Potion?" Both Guan Xiaofei and Su Qianqian, although they had some guesses, couldn't help but pause when they heard the term. "Hubby... you actually developed the Genetic Evolution Potion?" Guan Xiaofei asked, unable to believe it.

"Are these changes the result of the Genetic Evolution Potion?" Su Qianqian said, understanding dawning on her.

Though they had witnessed Jiang Cheng's wonders countless times, this time they couldn't help but be shocked—if someone else said this, they would undoubtedly be considered crazy and not believed at all. But since Jiang Cheng said it, both Su Qianqian and Guan Xiaofei were inclined to believe it was indeed the fact. The Genetic Evolution Potion, a concept and term found only in novels, was successfully researched and developed by Jiang Cheng once again....

"Yes." Jiang Cheng nodded and said, "I indeed have developed the Genetic Evolution Potion—in these days at the lab, I injected the Genetic Evolution Potion into my body, causing so many changes."

Though Jiang Cheng spoke lightly, both Guan Xiaofei and Su Qianqian couldn't help but change their expressions.

Guan Xiaofei widened her eyes, showing a hint of panic, and quickly said, "Hubby, you actually experimented on yourself? That's too dangerous! Before you can guarantee a hundred percent success, doing experiments on yourself is too dangerous. Next time, even if you experiment on us, never on yourself!"

"Yes, yes." Su Qianqian, listening from the side, couldn't help but nod and said, "It's really too dangerous and shouldn't be done. Hubby, your actions are just too risky..."

Jiang Cheng, hearing this, felt a bit touched but wasn't angry at their questioning his Genetic Evolution Potion's success rate. He patted their heads and said, "Although you say so, how could I bear to experiment on you? You really know how to joke...."

"But it's still very dangerous for you to do this, hubby... how can you experiment directly on yourself?" Guan Xiaofei lay in Jiang Cheng's arms, drawing small circles on his chest with her hand as she softly complained.

"Yes... I also think it's too dangerous." Su Qianqian, leaning on Jiang Cheng's chest, remarked again, showing her discontent with his risky actions.

Jiang Cheng shook his head, smiling as he said, "You're overestimating the danger of this experiment. The Genetic Evolution Potion I researched is fundamentally different from the Genetic Mutation Potion—even if the experiment fails, nothing dangerous can happen—moreover, with my research and repeated deductions, the result is successful. The chance of failure is, at most, one in ten million, even if it fails, it would just mean a few days of weakness. You're overthinking this."
