Suddenly, she seemed to understand.
"Lu Zhe, you're so bad, how could you use this stuff to make yogurt??"
"Are you stupid? Jiang Yao is jy, I'm the original poster!"
Tang Xiaoguo thought for a moment: "Then who's Ice Sis?"
Shen Bing shrugged: "Of course it's bj!"
"What exactly is going on?"
Shen Bing said: "The yogurt you're eating is fermented with Jiang Yao's saliva, how's the texture?"
Tang Xiaoguo was stunned: "Huh?"
Ning Shu picked up another cup: "This one is extracted from Jiang Yao's intestines, want to give it a try?!"
Tang Xiaoguo was confused: "Huhhh?"
Jiang Yao was annoyed: "Classmate, couldn't you introduce your own?"
Qian Qian also took a cup: "There's also yours, Xiaoguo."
Tang Xiaoguo was even more confused: "Ahhhhh?"
She took three steps back, her face full of shock and horror: "Oh my god, what have you all done behind my back?"
Lu Zhe looked rather proud: "Successfully made yogurt."
"That's so gross!"
Lu Zhe nodded: "I discovered that the yogurt fermented with intestinal extracts basically all failed. The bifidobacteria still couldn't defeat the E.coli to take over. The ones with saliva, armpit and toe jam extracts were successful. And the most successful one was this cup, who was that extracted from?"
Lin Qianqian thought for a moment: "I know, it's Xiaoguo's?"
Tang Xiaoguo was dumbfounded: "Mine?"
"From the large intestines?"
Qian Qian shook her head: "I originally wanted to do that, but was afraid of hurting Xiaoguo, so I used something else instead."
"What else?"
"Um...I don't know how to say it. I just didn't expect there would be some there too."
Lu Zhe nodded: "There is, and quite a lot of it too, that's why there's that subtle sour flavor! The main role of lactic acid bacteria is to decompose glycogen into lactic acid, keeping the secretions in a weakly acidic environment at all times to inhibit the growth of other pathogenic microorganisms."
Shen Bing was shocked: "You know all this?"
"If I tell you I learned this from A Million Whys, would you believe me?"
Shen Bing chuckled and said softly: "You can only fool a few girls, but you can't fool me!"
"Oh? Then what do you think?"
"Hmph, must've looked up a lot of related information when you were in school!"
"I..."
Seeing Shen Bing's knowing look, Lu Zhe gave her a thumbs up: "As expected of Detective Bing, nothing gets past you!"
Shen Bing nodded smugly: "That's right!"
So in the end, Xiaoguo's cup became the highest quality yogurt.
But this cup could not be drunk or sweetened with honey or sugar. It had to be used to ferment more yogurt.
As for the remaining five cups, Lu Zhe planned to use them to make stir-fried yogurt!
The method was quite simple.
He cooked the saltpeter dry, then re-leached out the nitrates, dried them, then put them in a helmet filled with water and stirred to continuously dissolve the nitrates to lower the water temperature in the helmet.
Next, Lu Zhe took out a Type 92 lunch box.
He poured the finished yogurt in, then added honey, fruit bits, and finally submerged the lunchbox in the water in the helmet!
When the nitrates dissolved, they absorbed a lot of heat, causing the temperature inside the lunchbox to continuously drop, turning the yogurt inside icy and semi-solid.
Lu Zhe worked attentively and skillfully, just like an outstanding worker with many years of experience on the production line.
When all the nitrates had dissolved completely, the yogurt in the lunchbox finally froze into ice cream.
Scooping a spoonful with a little bamboo spoon, it was ice-cold and delicious, refreshing one's heart and pleasing one's taste buds. The few girls were surprised. Lu Zhe and Shen Bing only had a small spoonful before the little lunchbox was scraped clean by the young girls.
"Xiaoguo really is the best, able to produce so much high quality stuff with lactic acid bacteria!"
Tang Xiaoguo wiped her mouth: "I didn't even agree back then!"
"You were sleeping like a pig, didn't disturb you at all!"
"No wonder Lu Zhe stood you up."
Tang Xiaoguo mumbled about her dream experience.
At this moment, Lu Zhe added: "Everyone's seen the uses of saltpeter now, right?"
"It really is a little unexpected."
"So next, I need everyone to buck up and head to the latrines to poop, and try to collect as much saltpeter as possible."
"Even toilet freedom is gone now!"
But despite the complaints, everyone deeply approved.
From now on, they had a renewable cooling material. As long as they were at the camp, they could eat stir-fried yogurt every few hours.
Lu Zhe gained another potential point.
Historically speaking, this was no less significant than the invention of the steam engine.
Extremely satisfying.
With mini fridges in the soil, large palm leaf fans, stir-fried yogurt, and a steady supply of spring water...
They finally didn't need to worry about heat stroke at the camp anymore.
The girls worked on building ladders while making yogurt.
And Lu Zhe had to start on the next step of his plan!
Stockpile food, build a sturdy, safe raft to successfully get through the shark territory to locate the spot where the plane sank, and successfully retrieve the items inside.
Sounded simple, but was extremely difficult in execution.
Just taking the bamboo raft - it wouldn't be so easy to complete!
Not only did it need to be sturdy, it also had to be able to hold a lot of items, otherwise making just one trip to retrieve a small amount of supplies would be too costly.
He spent an afternoon gathering a large amount of bamboo to form the raft's main structure.
Then he looked for suitable sail material!
But after circling the beach, he didn't find any suitable materials.
So he started thinking of other possibilities!
Using clothing definitely wouldn't work!
The resources were too scarce and they'd easily become tattered after soaking in seawater for too long.
Like, sheepskin, python skin, crocodile skin, monkey skin...
But slaughtering large numbers of wildlife for those would be too difficult.
The slaughtering, skinning, and stitching everything together would be extremely tedious no matter which step.
Could he only make straw mats?
He also needed provisions!
Lu Zhe decided to head into the jungle alone to see if he could find any bananas for provisions on their sea voyage.
