Chapter 255: How about I squeeze into your room?

Unfortunately, even though Xu Xu Qingzhou had lived a few extra decades and was adept at reading people, he never imagined that the cold and aloof Song Yao had fantasized several times about him "forcing" her.

Otherwise, she would have cooperated beyond measure.

The two walked back, passing a bubble tea shop along the way and buying two iced bubble teas; in Song Yao's words: "Exercise is for building health, not losing weight."

Night fell, and the orange-yellow glow of the streetlights stretched their shadows long, intertwining, then stretching again; by now, most of the campus had entered the exam review phase.

Students hurried past on the path, the campus thick with the heavy atmosphere of approaching exams—even the couples usually seen cuddling by the lake had dwindled by half.

People like Xu Xu Qingzhou and Song Yao, who went for a run yet still bought bubble tea and strolled leisurely around campus, were somewhat unusual.

Grades affected GPAs and eligibility for honors and awards.

Xu Xu Qingzhou's gaze swept over Xu Xu Zhengyang and Chen Chen Shiqi, "You two just came out of the library?"

Read!

Xu Xu Qingzhou nodded and swapped his bubble tea with hers. A moody little thing—she clearly wanted to drink his, but pretended to ask if he wanted hers.

Neither Xu Xu Qingzhou nor Song Yao worried about these things.

Song Yao emerged from the bedroom, drowsy—she must have been woken by the thunder and rain outside.

Xu Xu Qingzhou sighed. Moving into Song Song Xiaohua's bed? This road was long and fraught. In the master bedroom, Song Yao sat on the bed, equally troubled: Xu Xu Qingzhou had lately been eager to kiss her, especially fond of touching and fidgeting.

Moreover, the growth morphology of one-dimensional silicon nanowires shortened the diffusion distance of lithium ions, facilitating rapid electron conduction.

Lithium dendrites were one major cause, but the data fluctuations were still too large.

Song Yao ignored Xu Xu Qingzhou's nonsense, sniffed, snatched Er Miao from his arms, turned, and walked back inside, slamming the door shut with a "bang."

Due to severe volume effects causing particle pulverization, fresh silicon atoms continuously consumed lithium, making it difficult to form a stable solid electrolyte interphase in conventional LiPF6 electrolytes.

"."

Song Yao's eyes curved with delight; she took a long sip of bubble tea, her pupils sparkling. She'd found another advantage to dating: one bubble tea now gave her two flavors to taste.

The department realized having Xu Xu Qingzhou take the exam was a waste of time and waived it outright.

2. Besides lithium dendrites, another major reason for the sharp capacity decay of silicon anode materials is the corrosion of silicon by trace HF generated from the decomposition of LiPF6 in existing electrolytes.

"Not afraid." Song Yao saw through his thoughts—say "afraid," and he'd surely say: "Let me come sleep in your room."

Xu Xu Zhengyang: "Damn, what are you thinking? I called for ages and got no response."

"Yeah, they're eating over there."

Xu Xu Qingzhou ordered a meal with two meat dishes and one vegetable, his mind still on Professor Zhao's experiments.

The number of diners suddenly rose to four, the atmosphere lively; Xu Xu Qingzhou temporarily set aside lithium-ion battery matters and chatted with his long-absent roommate.

"Let's go. What day is this? First we ran into Kong Xian, now we run into you."

Online, they say boys need to release tension.

Song Yao bit her straw and asked: "Did you adjust your screening method?"

1. According to the data feedback, the intercalated lithium is captured by silicon atoms, not by the passivation layer formed on the silicon particle surface.

Yet, to Song Yao's surprise, Xu Xu Qingzhou nodded, looking relieved—this made her wonder if she'd overthought things.

He frowned, organized the data, and fed it into the pre-built analytical model.

Suddenly, it was a new week; since Sunday, a light, persistent rain had been falling.

"Pretty much. A few days ago, I incorporated some elements from the double integral method, then adjusted the counting function, trimming the redundancies."

"Just some lab stuff."

Serial No. 01 Silicon content (%): 50 Electrolyte type: AC Rate: 0.5C. After spending four hours calculating the data, Xu Xu Qingzhou wrote down the results. Song Yao nodded slightly, sipped her bubble tea, her bright eyes fixed on Xu Xu Qingzhou: "Do you want to drink mine?"

Although Song Yao wasn't a math major, they often discussed Xu Xu Qingzhou's work; she never brushed him off, listening attentively and occasionally nodding, murmuring "Mm."

!.

"No word yet from Johns Hopkins." Song Yao cared more about the proof of the Polignac conjecture than Xu Xu Qingzhou did, checking daily for new developments.

"See, even Er Miao's scared. You're the only brave one in the house—taking us in makes perfect sense."

It was mealtime, so even before noon, the cafeteria was packed; people ate while glancing at their laptops, then ate a few bites, then looked again.

Xu Xu Zhengyang looked utterly defeated: "Yeah, Professor Gu's Mathematical Analysis exam is Thursday—I'm numb."

As he wrote point three, Xu Xu Qingzhou paused. The computer clock read 11:40 a. m. He planned to head to the cafeteria for lunch; Song Yao was still in class, and since it was the last session of the semester, she'd eat with Zhang Qiong and the others afterward.

Library.

"Xu Xu Qingzhou, you just said you'd sleep in half an hour."

So… Song Yao lowered her head, her plump toes fidgeting nervously, cheeks flushing. She quickly patted her chest and muttered under her breath: "Who the hell wants to help him? Let him suffocate!"

Hmph, Xu Xu Zhengyang really needed someone to keep him in check.

Xu Xu Qingzhou briefly explained the situation to his girlfriend, cheerfully adding: "Overall, everything's still going smoothly."

Xu Xu Qingzhou had mentioned it might rain in a few days, but at 1 a. m., thunder boomed outside, and soon after, heavy rain pattered down as promised.

"Going to sleep now?" Xu Xu Qingzhou finished up, shut his computer obediently, hugged Er Miao, and asked: "It's thundering and raining—aren't you scared, being a girl alone?"

"Is Kong Xian here too?"

But according to current experiments, the results weren't good.

Xu Xu Qingzhou was about to find a seat when he heard someone calling his name—he turned and saw Xu Xu Zhengyang and Chen Chen Shiqi.

Xu Xu Qingzhou was comparing data from Week 1 of the experiment; from the initial charge-discharge curve of the nano-silicon powder anode, the capacity loss in Week 1 was severe.

"Yes."

"It can. You move."

Not a single update.

After nanosizing silicon, the lithium insertion/extraction mechanism of silicon nanowires greatly alleviates the phenomenon of active material pulverization and detachment from the current collector during cycling due to volume expansion.

Indeed, anyone admitted to Jingda was basically a grind.

Song Yao ranked first in her major, pulling far ahead of the second-place student; while others were still struggling through freshman textbooks, she'd already read third-year materials.

"I suspect there might be trouble in the proof." Xu Xu Qingzhou remembered that since Professor Stewart announced his proof of the conjecture, six days had passed.

"Then I'm relieved. But you don't know—I've been terrified of thunder since I was a kid, cowardly. How about I come sleep in your room?"

Back home, he showered, reheated last night's leftovers, ate, and both plunged back into busyness—one working on quantum institute algorithms, the other reviewing coursework.

Thunder and rain raged; even Er Miao hid trembling in Xu Xu Qingzhou's arms.

Xu Xu Qingzhou couldn't help but whistle in disbelief.

Seeing Xu Xu Qingzhou so happy, Xu Xu Zhengyang gave him a resentful look and protested: "Xu, have a little compassion, will you?"

Xu Xu Qingzhou sighed helplessly: "What can I do? Your suffering is something I can't truly relate to."
