The cooperation that Zhang Chengyan mentioned was that the Investigation Bureau would provide the materials and Lu Chengchuan would contribute the effort, and each would get what they needed.

Lu Chengchuan was naturally very happy about this. There were a lot of good things in the Investigation Bureau, and he had a lot of needs for martial arts. Cooperating with the Investigation Bureau was the right choice.

"Of course, I certainly hope to cooperate with the Bureau of Investigation."

At least now they have to cooperate. He needs to collect as many martial arts as possible and kill as many monsters as possible to strengthen himself.

"This is our special contact phone. Take it. If you need anything, you can contact Yaning. We will also talk to you through this phone if we have anything to say."

After agreeing on the cooperation, Zhang Chengyan took out a cell phone, and they communicated internally through a special phone. However, Lu Chengchuan was an external employee, and the phone he was given was a "standalone version", which could only be used to contact a specific person.

Lu Chengchuan took the phone and chatted for a while. Zhang Chengyan was busy and Lu Chengchuan also wanted to take a look at the two martial arts books in his hands. The two of them happened to have the same idea and soon he came out of the office.

"You're really impressive this time. After beating the FBI, you're now beating the military."

"Captain Zhou, please stop laughing at me. Please take me out. I'm afraid we'll be stopped by soldiers on the way." There was nothing to do now, and Lu Chengchuan just wanted to leave.

After all, this is the armed forces department, and it is not easy for him as an outsider to move around.

After making a joke, Zhou Yaning sent him out. On the way, Zhou Yaning couldn't suppress his curiosity: "How powerful are you? Is martial arts really that easy to practice?"

Is it reasonable that a person who is dying of illness can become a master in less than a month?

"I thought you, Captain Zhou, weren't a gossipy person."

"This has nothing to do with gossip. If you share your experience with others, nine out of ten people will be curious."

Lu Chengchuan shook his head and said nothing. Zhou Yaning was helpless seeing this. If the person didn't want to talk, could she arrest him and take him back for interrogation?

Zhou Yaning walked him to the gate of the Armed Forces Department and said, "Alright, go back by yourself. I still have things to take care of."

"goodbye."

Lu Chengchuan waved his hand and walked towards the nearby subway station.

Since the monsters appeared, there has been a team of armed soldiers patrolling every subway station. They are on guard against the appearance of monsters and also against people with ulterior motives coming in to carry out terrorist attacks.

When he was taking the subway home, his mother saw him come back and told him something.

She bought a second-hand house. They didn't need to renovate it, they just needed to buy some furniture and move in. Her mother said they were moving in the next few days, so she asked him to find some time to go with her to see the new house.

"Oh, I see."

Lu Chengchuan didn't have much expectations for the new house. His current thoughts were all on martial arts and monsters.

After returning to his room, Lu Chengchuan immediately flipped through two martial arts books.

Soon, with the help of the system, he spent forty days of his life to learn two martial arts.

There are so many good things in the Investigation Bureau. Among the two martial arts books given by Zhang Chengyan, there is a mysterious martial art called "Shrinking the Earth".

This martial art has only three levels: the first level can shrink to 20 meters, the second level to 50 meters, and the third level to 300 meters. This martial art is difficult to learn and master, and martial artists with poor talent will never be able to master it.

Lu Chengchuan has a system, so as long as he has enough lifespan, shrinking the earth will not be difficult for him.

The other is an external martial arts book called "Bone Shrinking Kung Fu". When the practitioner reaches perfection, he can control most of the bones in the body to shrink or expand his body size.

Two martial arts books appeared on the martial arts column, with the words "can be improved" behind them.

The bone-shrinking technique only requires two years of life to be mastered, so Lu Chengchuan immediately upgraded it to the highest level. However, the first level of the earth-shrinking technique requires fifteen years of life, which is a terrifying consumption.

But in order to be able to use the shrinking technique, Lu Chengchuan gritted his teeth and spent fifteen years of his life to upgrade.

In less than ten minutes, Lu Chengchuan's remaining lifespan was reduced from more than thirty years to fourteen years. He could not continue to improve his martial arts with the remaining skills, so he had to go find the monster.

At the first level of the Shrinking Earth Technique, Lu Chengchuan felt some changes, but he didn't know where the changes were.

He opened the door and saw the end of the living room. He took a step out and subconsciously used the shrinking technique.

The next moment, Lu Chengchuan saw the scenery on both sides rapidly receding. In an instant, he arrived at the other end of the living room and almost hit the wall.

The rental house is only more than 50 square meters, and the entire room is less than 20 meters long.

"Is this the Shrinking Earth Technique?"

Lu Chengchuan just felt novelty. This thing was beyond his expectations. The feeling was also very strange. He could instantly cross a distance of several meters with just one step.

However, the shrinking technique also consumes a lot of internal energy. He could feel the obvious consumption of internal energy just by taking a step.

After it got dark, Lu Chengchuan left the rental house and found a slightly remote place where he planned to practice the art of shrinking the earth.

On the deserted street, Lu Chengchuan looked not far away, his eyes fixed on a position about ten or twenty meters away from him.

The next moment, his figure passed through layers of space and instantly appeared at the position he had locked onto.

Lu Chengchuan took ten steps in a row and covered a distance of two hundred meters in one go, and his internal energy was consumed by almost one-fifth. The internal energy consumed by using the shrinking technique was really not small.

After consuming half of his internal energy, Lu Chengchuan stopped practicing and returned home.

......

In the first month after the monster appeared, at night, Lu Chengchuan stood on the balcony and looked at the scenery outside the window.

He has moved to a new house. The new house his mother bought is on the twelfth floor. His building has a good view and there are no obstructions. He can see very far away standing on the balcony.

There was no moon or stars in the city at night, and Lu Chengchuan could only see sparse clouds.

Just as he was about to return to his bedroom to rest, spots of light suddenly appeared in the night sky. The spots of light appeared so suddenly that Lu Chengchuan's attention was immediately drawn to them.

The light spots were small and very far from the ground, but they were extremely bright and could be seen clearly by anyone with normal vision. Hundreds of light spots broke through the clouds and suddenly exploded like fireworks, rapidly spreading in all directions.

"Meteor? Or a monster?" Lu Chengchuan muttered to himself.

This thing was not right, it didn't seem normal, and he couldn't help but think it was a monster.

Many people in Anyang City saw this scene. They took out their mobile phones to take pictures of it, while the staff of the city's meteorological bureau were anxiously watching the rapidly spreading "meteor".

They did not detect any abnormal atmospheric phenomena. These meteors seemed to appear out of thin air without any warning. Their superiors were questioning them and asked them to give an answer as soon as possible.

"What's going on? Is it a problem with the equipment? Or are we just not detecting it?"

The leader of the Meteorological Bureau was under a lot of pressure. He had received several calls from his superiors and he wanted to answer but didn't know what to say.

Lu Chengchuan watched as a meteor flew toward Anyang City. A loud bang was heard, and something fell to the ground. The exact landing point was unknown, but it was probably not far from Anyang City.

Ding ding ding... Ding ding ding...

The phone rang. It was the ringtone of the Investigation Bureau's exclusive mobile phone. Lu Chengchuan answered the call immediately.

"See that thing in the sky? What is that?"

Zhou Yaning's voice came, and there was a hint of anxiety in her usually cold tone.
