Chapter 6 — Having occupied a Business Seat, I went straight to First Class

I immediately grabbed the car keys and rushed out of the office.

“Miss Khuong, where are you going?”

Tieu Ha called out from behind.

"I'm going out for a bit, the company will be handed over to Lam Phong and Truong Vi!"

I didn't turn around and walked straight into the elevator. The car sped away into the night. I went to the old neighborhood on the other side of the city. The small house containing all childhood memories... still stands quietly in the alley. The door was covered with a layer of time dust. I opened the door. The familiar smell of old paper, of old sunlight... rushed in. he is still here. I don't have time to be nostalgic. I rushed straight into my father's office. Everything in the room... was still the same as the day he left. I started rummaging around. Bookshelf, drawer, under the bed... anywhere I can hide documents, I don't miss them. But besides specialized books and a few household items... nothing. No contract, no papers, no clue. Could it be… is there really nothing left? I sat down on the ground, a feeling of disappointment and emptiness coming over me like a wave. Just when I was about to despair, my eyes suddenly stopped at the top of the bookcase. A small wooden box. Very old. Very normal. That's the box I used as a child to store "treasures". Later, my father said he also needed a place to store his "treasure"... and then "borrowed" it. I'm like a dying person reaching for a lifeline. Immediately pulled up a chair and reached down to take the box down. Unlocked box. Inside there are no papers, no contracts. There is only a thick notebook with a dark brown leather cover. My hands shook as I opened it. Familiar handwriting appeared. It's father's. This is not a diary. This is a work notebook. Each page... is dense. Ideas, inferences, algorithms, every important line of code... all are recorded in detail. Tears immediately welled up in my eyes. is the most valuable legacy he left behind. I quickly wiped away my tears and continued flipping. I hope… in these technical lines, there will be traces of truth. In the later part, the handwriting begins to get more confusing. He doesn't just write about code anymore. Which began to record conflicts with Manh Quoc Dong. Regarding development direction. From a technological standpoint. Every line… is powerless. It's all pressure. Until the last page. That page doesn't have an algorithm. There are only a few lines of text.

"Manh Quoc Dong has changed. He wants to pull those brutal capital in and turn Khai Minh into a money-making tool."

"I don't agree. This is our passion, our ideal."

“He used the patent issue to pressure me, saying I had no choice.”

“I may not be able to compete with him in the marketplace, but I must leave one last layer of insurance… for my ‘child’.”

“I buried a ‘founder mark’ at the bottom of the algorithm.”

“It is a special encryption string, only I can activate it.”

“Once activated, any system based on this algorithm… will logically self-destruct within twenty-four hours.”

“This mark will never be discovered… unless someone solves the lock I left behind.”

“Meng Quoc Dong, if one day you betray our ideals…”

“Then this entire empire… will be buried with my ‘child’.”

“I call it…”

“Project ‘U Linh’.”

I stared at the last four words. The blood in my body... boiled. I found it. This is the deadly weapon my father left behind. I immediately pulled out my phone and called Lam Phong. My voice trembled up with excitement.

“Lam Phong, I need you to find something.”

“Something… hidden in the code twenty years ago.”

“A ‘Ghost Spirit’.”

I took the notebook and rushed back to the company at my fastest speed. The technical room's lights are still on. Everyone was exhausted, but their eyes... were bright.

“Miss Khuong!”

Lam Phong immediately stepped forward.

“What's the situation?”

"We have transferred all the evidence to lawyer Ly. He completed the lawsuit overnight. After the press conference this morning, the summons and notice of prosecution will be sent directly to Manh Phi's desk."

I nodded. That's just a superficial attack. just started. I put my father's notebook on the conference table.

“Lam Phong, call your best people.”

“We have a new mission.”

My voice lowered. Lam Phong did not ask further. He immediately called three people. These are all people who have been with me since the first days. People... I can put my absolute trust in. The atmosphere in the room… changed. Something… huge… is about to begin. The meeting room door closed. I opened the diary, flipped to the last page, and placed it in front of everyone.

“I need you guys… in the shortest possible time, to find this.”

“Project ‘U Linh’.”

When Lam Phong and his team finished reading those words... The whole room fell into absolute silence. No one said anything. Only eyes. Unbelievable. A backdoor buried for twenty years. One mark can cause the entire system to self-destruct. This thing… has gone beyond the technical scope. It's like a work of art. A work... that smells of destruction.

“Miss Khuong… is this… true?”

A young programmer asked, his voice shaking.

“If it's true… then my father… is truly a genius.”

I looked straight at them.

“Our job… is to wake it up.”

“But… it's too difficult.”

Lam Phong frowned tightly.

“Code twenty years ago, the architecture was completely different from today.”

“The information left behind was just a name… no key structure, no instructions.”

“It's like finding a needle in the ocean.”

I turned to another page.

“There are clues.”
