Eliminating them one by one gradually accumulated huge psychological pressure.

Not only is the suspect under great pressure, it also makes the audience extremely nervous.

A tension filled the entire conference room, and the air seemed to be compressing and about to explode.

Everyone held their breath, looking at Zhou Lu for a while, Gong Ziwen and Gu Chengxiang for a while.

One is an old professor with gray hair, an authoritative expert in the field of architecture, with rich and profound knowledge and ability.

One is a double-major master's student from a humble family, with an unlimited future and an introverted personality.

And Zhou Lu, the youngest with a slightly immature face, seems to be the leader of the situation in the conference room, but most people believe in him.

He stared at Gu Chengxiang with burning eyes, but said nothing.

Apparently, he believed Gu Chengxiang was the murderer.

But Zhou Lu didn't speak, and no one dared to make a sound in this atmosphere. The conference room was so quiet that you could hear a pin drop.

One second...

Five seconds...

Ten seconds...

"Hehehehe..." Gu Chengxiang suddenly laughed sinisterly, but still didn't raise his head and asked, "When did you find out?"

Everyone was astonished.

The humble academic master who has always been docile and shy laughed like this, which overturned his personality.

Gu Chengxiang's abnormal statement just shows that he acquiesces that he is the murderer.

The most shocked person was Chai Lu.

Her eyes were wide open, her mouth was wide open, and her jaw was almost dislocated.

Thinking back to last night, she actually lured the murderer who killed her entire family into her bed. A deep sense of fear arose from the bottom of her heart and spread, making her tremble uncontrollably.

Zhou Lu said indifferently: "When I eliminated Li Huaming, your breath was unstable and there was dark and evil power in your body, so it is 100% confirmed."

"You're awesome. I didn't expect that there would be someone as capable as you in the high-profile department. You're so close and careful. I thought it was done flawlessly."

Gu Chengxiang raised his head and looked directly at Zhou Lu, his eyes were rich black, not only the pupils were black, but the entire eyeballs were inky black, and his smile looked very weird.

"Haha, you are indeed pretty good. You have a very deep routine. You put one of these ants on each person, so that the people around you will be infected with a dark atmosphere, giving you a cover, but it really can't be called seamless."

Zhou Lu spread his palms, and in his palm lay an ant corpse the size of the fingernail of his little finger. What was strange was that the ant had no color and was almost transparent. It was impossible to see clearly unless he looked closely.

Gu Chengxiang also put one on Zhou Lu, but it was killed by Zhou Lu before it could reach his body.

"Gu Chengxiang, you, why are you doing this?" Chai Lu couldn't help shouting.

Gu Chengxiang's voice was sad and angry: "Why? Jie Jie Jie... Of course, you must have forgotten that ten years ago, on the land that your Chai family wanted to develop, there was a so-called nail house."

"You demolished it overnight, and a mother was crushed to death in her sleep. You paid for the incident. The excavator driver took two million and a house, and was sentenced to two years in prison for the crime. But all the masterminds behind the scenes are at large."

"My mother's son, who was a first-year junior high school student at the time, saw his mother being crushed to death. He grew up overnight and revenge for his mother became his only goal in life. He firmly believes that it is never too late for a gentleman to seek revenge in ten years."

"He was admitted to a key university with excellent results and studied law, but the more he studied, the more he discovered that it was impossible to use the law to deal with people like you. He became even more angry, but he suppressed his anger and studied architecture again, and then reiki

After recovering, he discovered mysterious power in an underground ancient building..."

After some narration, everyone understood Gu Chengxiang’s motive for killing.

No one interrupted him. Everyone, including Zhou Lu, had mixed feelings in their hearts.

This is a greater tragedy caused by a powerful force.

Obviously, the mother Gu Chengxiang mentioned was his mother. The boy in the first grade of junior high school who saw his mother being pushed to the house and crushed to death by an excavator was none other than Gu Chengxiang himself.

The incident happened ten years ago. The young man was determined to avenge his mother. Through study and opportunity, he gained knowledge and strength and returned to destroy his enemy's family.

"You are very smart and cruel. You killed people in two buildings to cover up the murder of Chailicheng's family, and then blamed the scumbag project." Zhou Lu said in his mouth, but was silently on guard.

Gu Chengxiang held it in for ten years before he had the chance to tell it. It was strange that he was not in a hurry to escape and seemed to have something to rely on.

When Team Leader Zeng saw that Gu Chengxiang showed no signs of resistance or escape, he did not rush to order the arrest. Gu Chengxiang revealed all the doubtful points in his case, thus saving the time of interrogation.

Professor Gong's chin trembled and he was so frightened that he could not speak.

He never expected that the murderous maniac who caused hundreds of casualties would be his proud disciple who had been following him all this time.

Sikong Feiyan was amazed. It was the first time he saw Zhou Lu solving a case. He was nervous and exciting.

But Zhou Lu's layer-by-layer reasoning and precise method of uncovering the murderer made her amazed and proud.

"Humanity itself is evil. No one is innocent. Killing hundreds of people does not matter." Gu Chengxiang had no sense of guilt at all for killing so many people. Instead, he was full of contempt for human beings, as if he had a serious anti-human mentality.

"You speak as if you are not human." Zhou Lu touched his nose.

After witnessing the tragic death of his mother, Gu Chengxiang's mentality was distorted. He suppressed his revenge and anger in his heart and pretended to be indifferent. Over time, this caused an obvious split personality in him.

To avenge one's mother and kill the culprit, the existence of righteousness and filial piety is somewhat excusable from a certain point of view, but to cover up the truth, deliberately knocking down two buildings and causing a large number of civilian casualties is unkind and unjust.

It was an unforgivable crime.

Poor people must be hateful!

"I have far surpassed ordinary humans and evolved into a higher creature." Arrogance rose on Gu Chengxiang's face.

"You killed my whole family, why didn't you kill me?" Chai Lu asked.

"I can kill you at any time. It's too easy."

Gu Chengxiang muttered words and made some kind of monosyllabic sound.

No one could hear clearly, and Zhou Lu could only hear the sound of "buzzing...", which was similar to the sound of some kind of insect.

suddenly,

"ah……"

Chai Lu screamed miserably, fell to the ground and convulsed, vomiting blood, and her face was as white as paper.

in a blink,

Her body straightened up and her fragrance disappeared.

It happened suddenly, less than three seconds in total.

Most people were shocked and did not react, but Zhou Lu stared at Gu Chengxiang and could not be distracted.

Sikong Feiyan reacted quickly, ran over and checked Chai Lu's breathing and pulse, shook her head and said, "She is dead."

It was too late to save her and we had no idea how she died.

There was no mana fluctuation in any of Gu Chengxiang's movements, and the words he silently recited didn't sound like a spell.

Zhou Lu's expression changed and he said, "Turn her body over."
