Liu Feng absolutely can't figure out what medicine Lin Li is selling.

Because it could be anything.

And it's not just medicine; you could call it a mini department store.

The "Fire Separation Sword Nourishing Gourd" in Lin Li's hand, besides holding the "Invisible Sword" for sword nurturing, mainly serves as a large storage space.

Right now, there's a wide and rich array of supplies inside, food, daily necessities, even some clothing, you name it, including medicine for common and sudden illnesses. Lin Li has accumulated some here and there, just in case.

This blood pressure medication is stored in the gourd, and Lin Li thought he would make use of it today, so he took it out to show off, planning to put it back in the afternoon.

But it definitely isn't easy to explain to Liu Feng, so in response to his inquiry, Lin Li casually said, "Not much, around thirty bucks, but I think it's worth it for a happy moment."

"Lin Li... your family must be pretty well-off, huh?" Liu Feng said, looking at Lin Li, losing his friendliness, feeling a regrettable barrier forming between them.

"Just an ordinary family," Lin Li waved it off, "I just have some ways to earn pocket money, so I'm a bit free with my spending."

"What ways?" Liu Feng's eyes lit up, leaning closer with lowered voice and expectation, "Could you show me? I really need the money!"

Though the apprenticeship pays a salary, it's honestly not much, as daily expenses can consume eighty or ninety percent of it, barely making ends meet.

Seeing Liu Feng's sincerity, Lin Li hesitated for a moment, then leaned in to offer some insight:

"Brother Liu, God gave people two kidneys and two lungs, yet you only need one to live. Why do you think that is?"

Liu Feng: "?"

Seeing Liu Feng seemingly didn't grasp the essence, Lin Li had to continue hinting:

"Brother Liu, remember, the first shot by armed guards in cash transport trucks is a blank;

Brother Liu, also remember, people's spare money is idle in banks, looking idle to me;

Brother Liu, remember that your backside can do more than relieve itself; sometimes smelly places can bring fragrant money;

Brother Liu, lastly, remember a big one: there's a guard change at Yuquan Mountain at eight p.m.

Alright, brother, I can only give you these hints; the rest you must figure out yourself."

Lin Li finished speaking, nervously glancing around as if worried about eavesdroppers.

Liu Feng: "..."

Something seems to be fanning around.

Oh, it's the corner of his twitching mouth.

Lin Li! What the hell are you seriously and cautiously talking about?!

Except for the rear end, none of those money-making ideas are viable for humans, right?! Post-factum doesn't one get sliced like cold cuts?!

"Forget it... forget it..." Liu Feng fully accepted the reality, understanding all the more what existence Lin Li truly is, sighed deeply, and awkwardly waved his hand.

Just then, Zheng Hong returned from the restroom, neatly changing the topic, "Master's back. Let's get ready to work." 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

Zheng Hong came closer, rummaging through his briefcase, fetching out a pair of spare insulated gloves and an insulated rod, handing it over to Lin Li: "Take it, safety first."

"Thanks, Master Zheng," Lin Li accepted and wore them, while curiously asking, "By the way, Master Zheng, how long will this take? Can we finish it by the end of the noon break?"

"A single noon is definitely not enough; we haven't brought the tools," Zheng Hong shook his head:

"Today's only cleaning dust and grime, then inspecting all equipment to identify outdated or outright broken components, making a list for replacement. I'll prepare everything based on the list, coming back the next day for installing and replacing.

If there aren't many items to change, we'll fix it in two noons; if it's a lot, it may take two or three noons. We should wrap this up within the week. Lin Li, will you join us for all the sessions?"

"Got it." Lin Li nodded, "I'll be here until it's fully refurbished and maintained."

"Okay," Zheng Hong didn't continue, prepared his gear, and led the way into the distribution room: "Liu, come along, Lin Li, you stay at the door, you can watch but don't come in yet."

"Coming, Master."

"Alright."

Once inside, Zheng Hong found the main switch, getting ready to cut the power, while Liu Feng stood by with the insulated rod held high, looking ready to strike someone.

As Zheng Hong opened the distribution cabinet to work, he casually explained to Lin Li watching at the door:

"Although nothing unexpected usually happens, I've already taken protective measures, but just in case, if I show symptoms of electrocution, Liu will use the insulated rod to separate me."

"I see." Lin Li nodded, "Master Zheng, I'd love to... I'd love to help you."

It seems Zheng Hong is a nice guy because Lin Li heard old electricians gradually enhance their safety awareness: the first year, they work with bare hands, the second year with a stick, and by the third year, they have assistants do it.

Yet Zheng Hong still handles it himself, a real commendable act.

"That won't be necessary," Zheng Hong had already pulled the main switch down, effectively cutting power to the teaching building, with the electrical hum in the distribution room entirely gone.

Nevertheless, Zheng Hong wouldn't let Lin Li in, opting to use a voltage tester to ensure all circuits were fully disconnected, confirming there was no residual charge.

Lin Li grew curious; if at that moment he silently used the Qingzheng Thunder Control Technique on Zheng Hong, causing him to jitter, would Liu Feng frantically hit him?

Lin Li just entertained the thought; this setting wasn't right for such jokes.

If Bai Bufan were in Zheng Hong's position now, Lin Li wouldn't have hesitated at all.
