Each key unit is equipped with a monitoring center that can observe the city's conditions and make timely responses.
Sun Yatian took Lin Yu to the monitoring center. A whole wall of large screens was used to monitor every corner of the city.
Sun Yatian seemed to be very skilled in adjusting surveillance. After asking through his walkie-talkie, he quickly learned from the security team at the door the time when the three captains left.
At the same time, the city defense army also received an order prohibiting the three people from leaving Firestone City.
"The city defense army reported back that they were not included in the records of leaving the city."
After Sun Yatian arranged everything, he reported the information to Lin Yu, who was now his superior.
Lin Yu felt relieved. It was good that he didn't leave the city. If he did, it would be difficult to find these people.
The situation of these three people was also brought to him.
Squad leader Chen Hua, a four-star distortion card master, squadron leader Liang Qiu, a five-star poison card master, and captain Qian Bai, a five-star elemental summoning card master.
The cards of the main deck and the backup deck are also in the information. The decks of these card masters are quite satisfactory.
Lin Yu moved his neck, put the information away, and waited for the results of the surveillance investigation.
Soon, the three people appeared at the end of the surveillance and formed a movement trajectory on the map of Firestone City. Based on the trajectory, they could successfully determine their direction.
That was the gymnasium in Flint City. It was already dark. What were they doing in the gymnasium?
Lin Yu was a little confused and asked Sun Yatian on the side: "Is there anything special in the gymnasium?"
Sun Yatian thought carefully and shook his head.
The Municipal Gymnasium is a necessary building in every city. He has attended some games there in the past, but he really doesn't know what's special about it.
"Okay, you and I go to the gym and catch the three of them."
Lin Yu waved his hands, got up and went out, heading downstairs.
After leaving the building, Sun Yatian drove him towards the stadium in the night.
The gymnasium is a certain distance away from the Disaster Management Bureau building. It is on the other side of the city and it takes more than half an hour to drive.
By the time they arrived, the lights in the stadium had been turned off.
There was silence nearby. Lin Yu got out of the car and asked the Insect Queen to summon bugs and began to go deep into the gymnasium to explore the whereabouts of the three people.
Only then did Sun Yatian realize that the leader next to him was using a Zerg deck.
Without Lin Yu's order, Sun Yatian did not dare to act rashly. He could only wait for the Zerg to investigate. The cold gymnasium was filled with the sound of insects flapping their wings.
Lin Yu's cell phone rang, and it was Bai Jin's call.
"How are you doing there?" Bai Jin's words came from the receiver.
"With three unexpected gains, I am arresting them."
Lin Yu said.
"Okay, then I'll go to the association first. I've arranged manpower for the city defense army. People from all units and trading companies are prohibited from leaving the city. Let's try to solve all this tonight."
After Bai Jin finished speaking, he hung up the phone without waiting for Lin Yu's reply.
Lin Yu put away his cell phone and continued to wait for the investigation results of the Insect Queen's command of the Zerg. Sun Yatian on the side heard the conversation between the two and knew that tonight, things were going to change in Flint City.
The Insect Queen silently directed the insects to scatter and search.
After a while, she made a discovery, screamed, took Lin Yu's arm and flew towards a certain place.
Sun Yatian quickly followed and ran in the direction Lin Yu left.
The location where the Queen of Insects is located is on the side of the stadium. The door here is not locked, and it says Sewage Treatment Room.
"Sewage treatment room?"
Lin Yu frowned and asked the Insect Queen to gather all the Insects together, then opened the door and walked in.
There is a downward staircase inside, and there is no peculiar smell.
Sun Yatian also followed, wondering: "Sewage treatment room, what are they doing here?"
This is where the sewage discharged from the entire stadium is gathered. After treatment, it becomes industrial water, environmental water and other non-potable water.
Lin Yu couldn't figure it out either, so he took the Insect Queen directly downstairs.
Unlike Bai Jin, he was able to discern dangers. In order to prevent traps, a large number of scavengers gathered under his command and crawled forward along the wall.
If there are any traps, the scavengers will trigger them first.
However, he was a little worried and walked half way, but did not find that the trap was triggered. The two of them arrived at the second underground floor, where the sewage treatment room operates.
There were different equipment placed in the open space, and there was a strange smell in the air.
It should smell like some kind of material used to purify sewage.
Lin Yu waved his hand, and the scavengers quickly crawled around along the ground, while some flew from the air to gaps such as ventilation ducts.
He believed that under such a dense swarm of insects, no matter where they were hiding, they would be found.
Sure enough, in less than a minute, the sound of fighting came from a corner not far away. Someone was using cards to attack his scavengers.
The underground space was small, so Lin Yu calmly used cards to summon the great lich.
This was a reasonable judgment he made based on the intelligence of the three people on the opposite side. The three creatures summoned by the archlich, abomination, ghosts and hounds, can restrain the opponent's three types of decks: distortion, poison and elemental creatures.
Fat Abomination rushed at the front, running towards the corner where the battle came from.
The floating screaming ghost emits silent sound waves in that direction. The soul screaming can cause creatures within the designated range to fall into a state of freeze.
It has little effect on Zerg and Abominations. For human card masters, it is a heavy blow that can make people dizzy and stiff.
Compared to the two of them, the Plague Dog arrived later. With a green light, it rushed to the front of the Abomination at an extremely fast speed, got into the corner, and began to bite.
At this time, Lin Yu approached calmly.
In that corner, there was a wretched humanoid tree man, avoiding the bites of the plague dogs.
However, the accumulated negative state of the disease has invaded his body. Even if it is transformed into a tree, he is still a diseased tree. Under the heavy exploitation of the curse, Hatred chopped it down with a butcher's knife and cut off the tree man's arm.
"Four-star Chen Hua, the distortion deck is Treant."
Sun Yalong said regretfully: "Chen Hua, don't resist, accept the investigation by the Imperial City Security Bureau."
"Hmph, if you can, kill me. If you kill me, all the ordinary people in this city will be buried with me."
Chen Hua, who became a tree man, spoke in a slightly hoarse voice, but there was a sense of confidence in his words.
Lin Yu suddenly thought of the other two card masters and asked sternly: "Where are the other two people?"
The other two people, one is a poison card deck and the other is an elemental summoning card deck. If we insist on saying that ordinary people in the city are buried with them, they can only be the poison card master.
The toxins in the cards are real. Without purification and treatment by a card master, the poisoned person can only suffer from the toxins.
Judging from Chen Hua's appearance, he could not tell the whereabouts of the other two people. Lin Yu frowned and could only look for traces on his own.
