As for the unlocking requirements for the eighth item slot, it's still an increase of 100, requiring a total of 5500 system currency.

The conversation between Zheng Hong and Liu Feng brought Lin Li's attention back to reality, as the two had started cleaning up the packaging on the floor of the distribution room.

"No problem, how about your side, Liu?"

"Everything's normal, Master!"

Seeing Lin Li's gaze come over, Liu Feng picked up some items and handed them to Lin Li: "Lin Li, help me throw these into the trash bin... hey, why are you lifting me, Lin Li?"

"Not doing it."

Liu Feng chuckled and elbowed Lin Li, struggled free, and threw all the trash into the bin.

Zheng Hong also walked out of the distribution room.

After handing the items to Liu Feng to handle, Zheng Hong took out his phone to make a call while looking at Lin Li:

"Lin Li, Liu Feng and I need to wait here for the logistics supervisor to come and inspect, but you can head back first. I hope these three days of observation have taught you something."

"Yes, I learned a lot," Lin Li nodded politely, then said goodbye: "Master Zheng, see you around."

"Haha, bye-bye." Zheng Hong waved at Lin Li.

Lin Li took two steps, then stopped and looked back, squinting and repeating: "Master Zheng, goodbye."

Zheng Hong: "Haha, bye-bye."

Lin Li: "Master, you should say 'Hmm, goodbye.'

Zheng Hong shook his head: "Haha, bye-bye."

F*ck, he's not even salty anymore.

Lin Li sighed, feeling he was mistaken to bring them lunch for three consecutive afternoons.

But since the task was complete, there was no need to linger, so Lin Li returned to the classroom.

On the way, he reminisced about the array encyclopedia Shanqing Daoist and Deng Wen left him. Now with five assignable mid-grade materials, he could set up many kinds of arrays.

However, since the materials can't be reused, ultimately only one could be set up, so he had to choose wisely.

Anyway, there was no rush.

Arriving at the classroom.

There were three people in the classroom at noon today, Wang Yuezhi, Chen Tianming, and Chen Yu Ying—Chen Yu Ying was here because she knew Lin Li could return before lunch was over.

"Lin Li? Why are you back so early today?"

Chen Tianming, unaware of this, glanced at the classroom clock upon seeing Lin Li and said, a bit puzzled.

"Dad finished work, finally can spend time with you." Lin Li said kindly.

"Perfect, come help me with these questions. I'm stuck and don't know what to do." Chen Tianming immediately waved.

Though there was another math-savvy Wang Yuezhi in the classroom, Chen Tianming didn't want to ask him.

As for Chen Yu Ying.

Chen Tianming was really worried that if he asked her, and Yao Qiaoqiao accidentally passed by Class Four and saw this, she'd be upset with jealousy.

Sigh, truly sweet troubles and constraints.

"Coming." With lunch break not officially started, Lin Li felt free to be a bit daring, so he walked over and plopped down on Zhang Haoyang's desk, taking the exercise sheet Chen Tianming was working on to look over.

"Which question?"

"This one."

"Ah, this question, let me see..." Lin Li scanned the question, then, squeezing his brow, looked up at Chen Tianming:

"Tianming, judging by your intellect, shouldn't you be called that Zhuge... Zhuge what?"

Chen Tianming, sensing he was about to be insulted, forced a smile: "Zhuge Tianming?"

"No, no, it's—it's—"

"Oh! Got it! It's Zhu-ge there!" Lin Li patted his head and pointed at Chen Tianming with surprise.

"I knew it, you mother..." Chen Tianming anticipated this, laughing and cursing.

Honestly, even if Lin Li truly praised him as Zhuge Tianming, Chen Tianming wouldn't be happy.

Because according to Bai Bufan's unofficial history, Zhuge Liang once used the mark recapture method and concluded that the Southern Region was all Meng Huo.

Bro, that's just foolish.

Even Chen Tianming knows, when conducting population surveys, the mark recapture method must not be used, as elderly and children have limited mobility and can be easily recaptured, greatly affecting survey results and leading to erroneous conclusions.

If Chen Tianming were in charge of the census, he would use the nuclear bomb survey method: just drop one nuke, consider the population data of an entire region as zero, no need to expend vast manpower, economical and efficient.

"Wasn't this question taught to you before? Are you a pig? The type hasn't changed, just the numbers, and you don't recognize it?"

Lin Li saw Chen Tianming still dared to space out, kicked his desk and scoffed.

"Was there? I don't remember." Chen Tianming chuckled nervously, "Maybe I just forget things easily as an important person."

"Calling yourself important, eh? Alright, let's go through the question first, it's simple..." Moving to Yang Bangjie's spot, Lin Li started explaining.

"...So, the final result is root two over two, choose B for this question." A few minutes later, Lin Li snapped his fingers after deducing the solution.

"But the reference answer says to choose C." Chen Tianming paused, looked at Lin Li with a peculiar expression.

"Then that answer is wrong, follow mine." Lin Li responded calmly.

"Holy sh*t—"

Expecting Lin Li to be embarrassed, Chen Tianming was surprised by this reaction, his eyes widened and he couldn't help but exclaim:

"The answer is indeed B, I just tried to fool you, but you're so confident, how can I ever reach your level."

"It's simple, just spend three bucks to buy me an iced red tea and three bucks for one yourself, and you'll be on the same level as me." Lin Li chuckled, pointing the way.
