As for applying growth promoters to fruits, it was indeed a massive undertaking. A single day wouldn't suffice, yet it was something he couldn't entrust to others.
Otherwise, if the fruits suddenly grew larger, the matter would be impossible to conceal.
Therefore, it had to be just him and his father. If only there were some way, some tool, to replace manual labor.
Unbeknownst to him, Tongtong seemed to sense his thoughts and suddenly sat up, "Dad, do you think it takes too much time for you and Grandpa to spray the fruits with growth promoters by yourselves?"
Liu Yifeng looked at Tongtong with astonishment. "Tongtong, how did you know what I was thinking? Do you have telepathic abilities?"
Tongtong giggled. "Daddy, do you really think I'm a celestial being, knowing everything?"
Liu Yifeng inwardly thought, wasn't he precisely that, knowing everything? Apart from his lack of talent in cooking, nothing seemed to stump him.
Before he could reply, Tongtong continued, "Actually, I inferred it from your and Grandpa's conversation, and I've already considered this problem."
"Weren't you asleep? When did you wake up?" Liu Yifeng's eyes widened.
Tongtong explained with a smile, "I woke up when Grandpa called, I just didn't open my eyes."
"You child, I thought you were still asleep! But you analyzed it correctly, I am indeed quite worried.
Relying solely on Grandpa and me to spray growth promoters on the seven to eight hundred thousand pounds of fruit would be too time-consuming and labor-intensive. I don't mind, but I'm afraid of tiring your Grandpa!"
"I'm fine. I've done this kind of manual labor since I was young. Yifeng, arrange for people to transport the fruits to the warehouse, and I'll slowly spray the nutrient solution myself, ensuring every fruit is covered. You can go back and take care of Tongtong with peace of mind!" As long as the fruits could grow larger and fetch a good price, he was willing to endure any hardship.
At this moment, Tongtong took Liu Yifeng's phone and said into the receiver, "Grandpa, I've invented an automatic sprayer. You'll just need to control its direction remotely."
Liu Yifeng, standing nearby, was once again stunned. "Tongtong, when did you develop this? How come I didn't know anything about it?"
Tongtong revealed an incredibly innocent smile. "Daddy, actually, as early as last time in the warehouse when I saw so many fruits that needed you and Grandpa to spray nutrient and growth promoters, I had the idea, but I never said anything.
Later, while you were cooking or practicing your martial arts in the kitchen, I would secretly go to the study to research machines that could automatically spray liquids.
Just two days before we came here, I had already invented a drone. Unlike the drones used for spraying pesticides outside, mine is lighter and has a greater load capacity.
It can spray a hundred pounds of liquid at once, and its density is very low.
When the time comes, Grandpa only needs to use the remote control to guide its direction."
After hearing Tongtong's words, Liu Yifeng couldn't hold back any longer. He hugged Tongtong tightly and planted a fervent kiss on his cheek.
Tongtong pretended to be disgusted and wiped his face. "Daddy hasn't brushed his teeth, it's stinky!"
"Even if it's stinky, I have to kiss you. Tongtong, you are truly Daddy's wise strategist, able to solve any problem! You're amazing!" Liu Yifeng said, then kissed him a few more times.
On the phone, Liu Chunsheng was also overjoyed. "My grandson is indeed smart, capable of building a drone himself. This solves a big problem for Grandpa.
However, Grandpa doesn't know how to operate it either. I'm completely clueless about these things!" Liu Chunsheng said with a troubled expression.
Let alone him, even Liu Yifeng had no idea. He knew about drones but had never played with one.
He thought such high-tech gadgets were only affordable for the wealthy.
He never imagined that Tongtong could build a drone with his own hands, and one with such power.
Heavens, what kind of prodigious son was this!
His gaze towards Tongtong was filled with admiration.
People often said fathers were heroes to their sons, and sons admired their fathers. But in his case, it was the other way around; he admired his son.
And it was sincere admiration. He could no longer describe his reverence for this omnipotent son.
At times, he couldn't help but wonder if Tongtong had some kind of system activated in his brain, granting him certain skills upon completing system-assigned tasks.
Of course, this was just his imagination running wild, fueled by too many novels. But he felt Tongtong's situation perfectly fit the tropes of a novel.
However, this thought was merely his flight of fancy.
Master You Li Zi, Tongtong's former master, had once said that the reason he had such a perfect son like Tongtong was because he had performed many good deeds in his previous life, and this was heaven's reward.
Therefore, Tongtong couldn't possibly have a system. And such things couldn't happen in reality; it was too fantastical.
He could only say that Tongtong's intelligence was incredibly high, perhaps even surpassing that of Edison or Einstein.
However, he had no intention of taking Tongtong for an IQ test, fearing the results might shock the entire hospital, leading to Tongtong being studied like a research subject.
Tongtong was unaware of his father's wild thoughts. He was earnestly replying to his grandfather's question, "Grandpa, it's okay if you don't know how to operate it.
I'll teach Daddy, and then Daddy will teach you. It's very simple, just like playing with a remote-controlled car. You'll get the hang of it with a few tries."
"Alright, once Grandpa learns, this job will be mine in the future." With this major challenge resolved, Liu Chunsheng felt a great weight lifted from his heart.
He then exchanged a few brief words with Tongtong before hanging up the phone.
"Tongtong, you're so smart, do you think Daddy is very stupid?" Seeing Tongtong hang up, Liu Yifeng asked with utmost seriousness.
Tongtong tilted his head, his large, blinking eyes innocently replied, "Does Daddy think he's very smart?"
This question utterly stumped Liu Yifeng, causing three dark lines to appear on his forehead.
Although it was a rhetorical question, it also served as an answer to his own query.
He had actually been deemed stupid by his son. While the assessment was true, it completely eroded his paternal authority.
Seeing his disheartened father, Tongtong giggled, "Daddy, whether you are very smart or not, in Tongtong's eyes, you will always be my most beloved Daddy, whom no one can replace!"
Liu Yifeng chuckled. This statement was almost worse than not saying anything; it was a double blow.
No, he had to establish his paternal authority in the future and make Tongtong admire him, becoming his superhero dad, he vowed inwardly.
"Tongtong, be good. It's getting late, go wash up quickly. Daddy wants to be alone for a bit!" Liu Yifeng said gently.
However, Tongtong reminded him of something, "Daddy, you should have your quiet time later. Aunt Xu, Aunt Su, and Uncle Kai Chen are all waiting for your call!"
Liu Yifeng then remembered that these people had called him last night and he hadn't answered. He immediately picked up his phone, opened his contact list, and called Su Wanru first.
The call was quickly connected. He apologized, "Wanru, I'm so sorry. My phone was dead last night, and I returned late, so I didn't call you back. Was there something you needed?"
