On the 27th floor of the hotel, Han Feng stood in front of room 2708 and gently knocked. Footsteps came from inside, and a deep male voice asked in Japanese, "Who is it?"

"It's me, Zhang Qian," Han Feng replied in Chinese, his deliberately lowered voice disappearing on the carpet in the corridor.

The door clicked as it turned, and Dai Yunfeng's weathered face appeared through the crack. The team leader from the state-owned new energy company looked to be in his early thirties, but his eyes behind his gold-rimmed glasses were bright and piercing. He quickly scanned the corridor before stepping aside to let Han Feng in: "Xiao Zhang, what's up?"

The moment the door closed, Han Feng's gaze swept across the entire suite. The layout was that of a standard business room; summit materials were spread out on the bedside table, and the laptop screen still displayed financial spreadsheets. His eyes lingered for a second longer on the TV cabinet and landline, confirming there were no signs of unusual signal transmitters.

"President Dai, I just wanted to ask how many days this summit will last." Han Feng rubbed his hands together, feigning distress. "We just received news from China that we need to go back to sign some paperwork for our new energy construction plant in your province."

As he spoke, he began searching the room for any listening devices. Although Lin Zhengguo had said that Dai Yunfeng was absolutely trustworthy, the level of danger and secrecy required for this operation was undeniable, so Han Feng had to be extremely cautious.

Upon hearing this, Dai Yunfeng laughed heartily, casually picking up a bottle of mineral water from the table and unscrewing it: "So that's what it is!" He took a sip of water, but his eyes behind his glasses conveyed a tacit message: "The summit will last for half a month. I can authorize the signing later via video conference."

After confirming there were no listening devices in the room, Han Feng relaxed his shoulder muscles slightly: "Then I'll trouble you, Mr. Dai. But could you please reveal the specific arrangements for the summit? We'd like to prepare our materials in advance." He pointed towards the door, indicating that Dai Yunfeng was safe.

Dai Yunfeng was aware of Han Feng and the others' existence; it was that person who personally instructed him to arrange their identities, so he cooperated fully in communicating with Han Feng.

Dai Yunfeng walked to his desk, deliberately making the sound of rummaging through documents, while lowering his voice: "Most of the time is spent in indoor discussions and inspecting results presentations; some sessions are even being held simultaneously." He pulled out a colored schedule, his finger emphasizing several dates. "What needs special attention is the visit of the Prime Minister of Country R on the third day, the Matsui Group's banquet tonight, and..." His fingernail traced a mark on the tenth day's schedule, "On this day, X Star Company is releasing its latest new energy technology, which is said to be groundbreaking."

Han Feng quickly memorized these timelines, outlining the framework of the operation in his mind. The Prime Minister's visit meant heightened security, the banquet provided an opportunity to make contact with the target, and the X-planet press conference was likely a cover for the gene technology.

"What if...we need to leave halfway through?" Han Feng carefully chose his words.

Dai Yunfeng adjusted his glasses, his voice returning to normal volume: "Just let me know in advance so I can adjust my schedule." He then lowered his voice further, "I'll arrange a legitimate business trip as a cover to buy you some time."

"Thank you, Mr. Dai." Han Feng nodded slightly, glancing at the crack in the door as he turned, but saw no suspicious shadows.

After leaving room 2708, Han Feng did not immediately take the elevator. Instead, he went down the fire escape to the 25th floor and then took the elevator. This counter-surveillance technique was ingrained in his bones, and he would instinctively execute it even in the absence of a clear threat.

The elevator doors opened on the first floor, and the hustle and bustle of the lobby rushed out. Han Feng had only taken two steps when he caught the sound of hurried Japanese spoken in the lounge area to his right. Ota Takeshi, who had just greeted them, was talking to two men in dark suits, his expression serious.

Han Feng slowed his pace, pretending to check his phone and prepare to open a translation app, but his ears perked up. Just then, Ota Takeshi suddenly looked up, their eyes meeting. After a brief moment of surprise, Ota Takeshi nodded in greeting, then continued his conversation with the two men.

Han Feng's heart tightened, then he smiled back at Ota Takeshi and walked out of the hotel lobby.

As soon as Han Feng stepped out of the hotel's revolving door, he caught a glimpse of a familiar figure on the street corner out of the corner of his eye—a slender silhouette and a familiar back view. But before he could focus his gaze, the person had already disappeared into the surging crowd.

"Is it her? It can't be such a coincidence..."

Han Feng instinctively wanted to chase after them, but was stopped by Ling's voice: "Do you still think this is China? Even if you followed, you wouldn't understand what they were saying."

"Do you have a way?" Han Feng asked in his heart, continuing to walk in the direction where the person had disappeared.

Zero was silent for a few seconds: "Found it, the language module, here you go."

A sudden, throbbing pain exploded in his temples, forcing Han Feng to lean against a roadside telephone pole for support. Countless unfamiliar syllables, grammatical rules, and common expressions flooded his consciousness like a torrent. The pain came and went quickly, and in the blink of an eye, the noisy Japanese conversations around him suddenly became clear and distinct.

"...The new game console will be released tomorrow..."

"...Where should we eat on our date tonight...?"

"...The stock price has fallen again..."

Han Feng blinked, the feeling of instantly mastering a language both strange and wonderful: "What kind of black technology is this?"

"Just a basic language pack," Zero's voice carried a hint of disdain. "I used to think it was useless, but now I see it's actually quite useful."

Han Feng tried saying "Hello" to the vending machine on the roadside in Japanese, and his pronunciation was so standard that even he was surprised. But when he tried to blend into the crowd on the street to gather information, he quickly discovered that cultural differences could not be bridged by language. The unique social distance, bowing etiquette, and subtle changes in tone of voice of the people of Japan made him, a "foreigner," feel out of place.

"Let's go back to the hotel first." Han Feng sighed, preparing to go back and wait for Su Wanwan and Liu Xiaoran, and also to check if Mu Xiaoxiao was still in R Country. That figure just now was too familiar. It even made him feel a little unbelievable.

As he turned around, Han Feng noticed a black Toyota Century parked at the side entrance of the hotel, its windows tinted dark. Three men in suits got out of the car, and the faint pattern on the cuff of the middle man made his pupils shrink slightly. It was a pattern of three overlapping maple leaves, the very symbol of the Makino family from the documents.

Before the other party entered the hotel, he returned to the lobby first. Han Feng, on the other hand, took out the RMB he had already exchanged at the convenience store, bought a cup of coffee, and then slowly walked into the hotel lobby.
