After the substitution marriage, I became the CEO's white moonlight

Under the dim light, Gu Mingyuan sank deep into the sofa, as if he had aged a lot in an instant. His heavy tone echoed in the quiet study: "He is... your father's sworn brother and a partner of the Gu Group. We all call him Lao K."

Gu Jinyan was shocked. He had never heard his father mention this person. He continued to read the diary and finally found the record about Lao K in the last few pages. In the diary, his father praised Lao K highly, saying that he was his most trusted partner and even transferred part of the company's shares to him.

"But why have I never heard of this person?" Gu Jinyan frowned, his heart full of doubts.

Gu Mingyuan sighed: "Back then, your father and Lao K started a business together, and the Gu Group was also founded by the two of them. But later, Lao K left for some special reasons and disappeared from the public eye. Your father never mentioned him to anyone, and we all thought he had..."

"Special reason?" Su Li keenly grasped the key information in Gu Mingyuan's words, "What is the reason?"

Gu Mingyuan looked solemn and was silent for a long time before he slowly spoke: "Back then, your father and Lao K accidentally discovered a secret organization during a business negotiation. This organization is powerful and ruthless, and has been secretly controlling the entire business world. And Lao K seems to have a close connection with this organization..."

Gu Jinyan and Su Li looked at each other, their hearts agitated. Could it be that this mysterious organization was the mastermind they had been looking for? And Old K was their representative?

In order to find out the truth, Gu Jinyan invited a professional investigation expert to investigate the identity and background of Lao K. At the same time, he and Su Li also began to look through all the ancient documents of the Gu family, hoping to find some clues.

As time went by, the investigation made no progress. It was as if Old K had disappeared from the face of the earth, leaving no trace. Just when they were about to give up, a long-forgotten family genealogy caught Su Li's attention.

The family tree records in detail the life stories of every generation of the Gu family, except for the generation of Gu Jinyan’s grandfather, where there is a blank.

"Why is this blank?" Su Li pointed at the blank space on the family tree and asked puzzledly.

Gu Jinyan was also very surprised. He had been interested in family history since he was a child, but he had never noticed this anomaly. He carefully flipped through the family tree and finally found the answer on the last page.

"The ancestors of the Gu family once made a deal with the evil demon in order to make the family prosperous. However, the law of heaven is reincarnation, and retribution is inevitable..."

This short sentence was like a thunderclap, exploding in the hearts of Gu Jinyan and Su Li. Could it be that the ancestors of the Gu family had made a deal with that mysterious organization? And now, this organization has come back for revenge?

"It seems that we have found something extraordinary." Su Li's face was solemn, with a hint of uneasiness in his tone.

Gu Jinyan tightly grasped the family tree in his hand, his heart filled with unprecedented fear. He realized that the enemy they were facing was far more powerful and terrifying than he had imagined.

Just then, news came from the investigation experts that they had found an important clue about Lao K.

"I found out that after Lao K left China, he changed his name and joined an international organization called 'Obsidian'..."

"Obsidian..." Gu Jinyan muttered to himself. He seemed to have heard this name somewhere before...

Suddenly, as if he had thought of something, he stood up abruptly, his face became extremely ugly, "Oh no, we've been tricked! This mysterious man, his goal is not at all..." "Oh no, we've been tricked! This mysterious man, his goal is not to destroy the Gu family at all!" Gu Jinyan stood up abruptly, his face was terribly gloomy, and the family tree in his hand was deformed by him. Su Li's heart also lifted up, she had never seen Gu Jinyan lose his composure like this, could things be worse than they imagined?

"If the Obsidian organization is really the mastermind behind the entire business world as the investigative experts say, then they simply don't bother to deal with the Gu family." Gu Jinyan paced back and forth in the study, speaking in a hurried tone, "This mysterious man, he approached the Gu family and me, he must have other purposes..."

Su Li also calmed down. She carefully recalled everything that had happened during this period, trying to find the answer from the clues. "You are right. If this organization really has such great power, it would not take any effort to destroy Gu's company." She frowned, "So, what is their goal?"

Gu Jinyan did not answer, but walked quickly to the desk, opened the drawer, and took out an ancient parchment scroll. Su Li recognized it. It was the treasure map passed down from generation to generation in the Gu family. It was said that it recorded the location where the ancestors of the Gu family buried the treasure.

"Do you remember the sentence in the family tree that 'the ancestor of the Gu family once made a deal with the evil demon'?" Gu Jinyan unfolded the scroll and pointed to a strange symbol on it and said, "I suspect that this symbol is the key to unlocking the treasure, and this so-called 'evil demon' is probably the 'Obsidian' organization!"

Su Li suddenly realized that if the target of the "Obsidian" organization was the Gu family treasure, then everything made sense. This mysterious man was lurking in the Gu family just to find the whereabouts of the treasure. And all their previous actions, including the attack on the Gu family, were just to cover up his real purpose.

"We must find the treasure before him!" Gu Jinyan said firmly, with a determined light in his eyes. Su Li also nodded solemnly. They must race against time to stop the conspiracy of the "Obsidian" organization.

Gu Jinyan and Su Li immediately took action. According to the clues on the treasure map, they began to search around the Gu family's old house. However, what they didn't know was that their actions had already been seen by others...

"The target has already started to act, should we..." A deep voice sounded in the darkness.

"No hurry, let them find it. The mantis stalks the cicada, unaware of the oriole behind..." Another cold voice sounded with a hint of teasing, as if everything was under his control...

In the old house of the Gu family, the ancient bricks and tiles reveal a sense of silence in the night. Different from the tranquility of the past, there is a tense atmosphere in the air tonight.

Su Li held a dim oil lamp and carefully compared the parchment scroll in her hand with the wall in front of her, trying to find the slightest clue. Gu Jinyan stood beside her, scanning everything around with sharp eyes, alert to any disturbance.
