PS: After hanging the water for two days, Baozi's illness is basically cured, and I haven't had such a serious cold for several years, and I should be able to restore fù from today onwards, asking for monthly passes and rewards.

"Since this has decided to stealthily assault, then the plan is as follows: I will infiltrate first, and after successfully infiltrating, I will obtain the structure of the institute and the location of the detainees, and then open the door of time and space for everyone to come in, and then the soldiers will be divided into two ways, one is led by my clone and Antti to rescue the detainees, and the other is led by me to assassinate and destroy the researchers and materials of the institute, and finally everyone evacuates separately after completing their respective tasks without waiting, do you understand?"

"Got it!" ×N.

"Alright, let's start grouping now. ”

The personnel were quickly distributed, Ouyang Yu chose Ingrid, Tia, Jasmine, Nova and Zhao Yingkong, and the rest were all on Anti's side, according to the information provided by Tianyu Yayin, the number of people detained was as many as thousands, most of them were ordinary people, so Ouyang Yu would arrange most of the people to be in a group with Anti, and they would carry Anti's return scroll to rescue the scattered detainees, the task was still very heavy.

After arranging a qiē matter, Ouyang Yu left the Undead Avenger alone, in order to ensure the greatest secrecy, she took the griffin and got off the plane at a distance from the research institute fortress, wearing a ghost suit and only relying on her own flying ability to continue to approach.

An hour, two hours, three hours, a distance that seemed not far away in the universe, Ouyang Yu flew with all his strength for more than three hours before he was attached to the external armor of the research institute fortress without any danger, and found an inspection window, Ouyang Yu quietly opened the window with the spy tool on the ghost energy suit. Then he successfully infiltrated the research fortress along this window.

After successfully infiltrating, Ouyang Yu did not take action immediately, but lurked in the maintenance pipe, using the small but powerful personal terminal of the ghost energy suit to hack into the internal network of the research institute. A diagram of the internal structure of the institute was retrieved.

The sprawling institute fortress is divided into four floors, the top of which is the personnel ecological living quarters. The living area has a well-developed natural ecosystem, with breeze and flowing water, forests and rivers, and many small animals, which can provide a healthy natural environment for millions of people.

The second layer is the research area, this research institute fortress is not only carrying out the real yàn mentioned by Tianyu Yayin, but many important and secret real yàn of the Hod Empire are also distributed in this layer, if they are all destroyed, it will definitely be a huge loss for the Hod Empire.

The third level is the fleet berthing area, where a regular fleet of the Hord Empire is stationed. The eighty-first fleet, hundreds of large and small warships, well-trained and well-equipped, fortunately, Ouyang Yu did not choose to attack head-on, even if there is the interference of Minovsky particles, her fleet may not be able to beat the other party, it is worth noting that the fleet also has a 100,000-strong marine corps stationed here all year round, with the 200,000 marines owned by the institute itself. The ground troops in the fortress of the institute are as high as 300,000, but Ouyang Yu of these 300,000 marines did not pay attention to it, and the most important thing for her is the ground troops.

On the fourth level, there is the maintenance and power area, where twelve large reactors provide sufficient energy for the entire research fortress. Ouyang Yu decided to take this place first, as long as the twelve reactors were blown up, the raging energy could turn the entire research institute fortress into tens of billions of tons of scrap iron.

Ouyang Yu put away his personal terminal, turned on the stealth function of the ghost energy suit, and walked along the maintenance channel towards the fourth floor. Although the maintenance tunnel is full of detectors and surveillance, the spectral suit can absorb radar waves. To prevent the infrared rays from overflowing, Ouyang Yu's own smell could not be transmitted. Under the optical invisibility again, the detector and the surveillance were useless, and she came to the fourth floor very smoothly along the maintenance passage.

Although the research institute fortress is located in the hinterland of the Hod Empire, the guards on duty inside are very serious and responsible, and every person who enters and exits the power area must be checked, Ouyang Yu originally wanted to avoid the inspection from the ventilation duct and enter the power area, but found that there are pressure detectors in the ventilation duct in addition to the conventional detectors, and if the pressure or gravity exceeds a certain pressure, she will be alarmed, and she doesn't want to fly in, the inspection here is so strict, there must be an energy detection device, and the magic reaction during flight cannot escape these sensitive detectors, so she can only think of other ways。

Ouyang Yu waited patiently for a short time and finally waited for an opportunity, a group of soldiers and the guards of the power area changed the guard, while they opened the door, Ouyang Yu jumped over their heads in three steps and two steps, the soldiers only felt a breeze blowing, when Ouyang Yu jumped to the top of the passage, the suction cup on the ghost suit activated and sucked her body, and then she silently sneaked in like a gecko.

The first thing you see when you enter the power area is twelve skyscraper-like reactors, each reactor can't be seen up and down at a glance, with a diameter of at least five kilometers, it seems to be a little difficult to blow them all at once with ordinary bombs, but Ouyang Yu has a way, since ordinary bombs can't work, use unusual bombs, several thigh-thick nuclear bombs were installed on the outer walls of several reactors by her and set the time, six hours, and the nuclear bomb can also be detonated remotely.

After doing a good job in the installation of the nuclear bomb, Ouyang Yu concocted the same method and left the power area and rushed towards the first layer, it took more than an hour for her to finally come to the first layer, when she walked out of the maintenance channel, she almost came to the surface of a certain planet, blue sky and white clouds, green trees, warm artificial sun, people warm and don't want to move, insects and birds chirp, the breeze blows, like a paradise, but unfortunately this peach source will be destroyed in five hours at most, miè becomes a ghost in the world.

Ouyang Yu found a forest and opened the door of time and space, and Antti and the others immediately rushed out, all of them wearing ghost suits and holding C-10 sniper rifles, like a group of Valkyries on the battlefield.

"This is the institutional map of the fortress of this institute and the location of the detainees. Ouyang Yu immediately passed on the information obtained to everyone, and then said: "I have already activated several nuclear bombs in the power area of the fourth layer, and they will explode in four hours and thirty-one minutes, everyone hurry up and act, Antti, you lead the team to ambush outside the prison where you are detained, and one of my clones will follow everyone to act together, and when I take people to the second layer of the research area, I will work together in the future, and my clone will provide you with military support." ”

After everyone hurriedly gathered for a while, they immediately separated, Ouyang Yu disappeared into the air with Ingrid, Tia, Jasmine, Nova and Zhao Yingkong, and Antti and a dozen others also left in the same way and sneaked towards the prison where they were held.

The defense of the second layer is also tight, there are trained soldiers everywhere, detectors and monitoring are everywhere, but this is not difficult for Ouyang Yu and the other six people, they ignored the detectors and monitoring and sneaked all the way to avoid the soldiers and came to the central storage room of the research institute, the super-large server inside can provide powerful computing power and data storage for all research, and the research materials of dozens of research units on the second layer are stored here, as long as the damage is destroyed here, the loss of the Hod Empire is difficult to estimate.

Ouyang Yu released all the clones, and the nine clones that followed down touched the monitoring room, guard room, weapon warehouse and other key departments, and each clone summoned more than a dozen vampire special forces, and Ouyang Yu's real body waited for them to send a signal.

In the special psychic link with the clones, one good news after another came, the monitoring room, the guard room and other key departments were already under the control of the clones, Ouyang Yu shouted in a low voice: "Do it!" The C-10 sniper step in his hand shot several bullets in a row and killed several soldiers not far away, Ingrid, Tia and others also followed, and together with Ouyang Yu, they quickly shot all the soldiers guarding the central storage room one by one.

Ouyang Yu quickly stepped forward and pasted explosives on the door of the central storage room, "Be careful of the explosion!"

"......Boom!" The gate was blown to pieces.

"Watch out for flashes!"

Several flash shock grenades were thrown into the broken door, and after a few muffled sounds, Ouyang Yu raised his gun and rushed into the central storage room under the cover of several people.

"Poof, poof, poof. ”

Ouyang Yu's sniper rifle opened fire in a row, hitting everyone who could see it, and then she summoned dozens of vampire special forces and ordered them to plant bombs in the central storage room.

"Uh......h Woo...... Woo......!"

Ouyang Yu's invasion finally alarmed the guards of the research institute, and a terrible alarm sounded, and a large number of soldiers were rushing towards them, and at the same time, the clones also came with the news that they had exchanged fire with the soldiers, especially in the weapons warehouse.

"Bomb planted!" reported a vampire special forces.

"Evacuate everyone!"

Ouyang Yu pressed the detonator, and hundreds of C4 plastic explosives in the central storage room exploded at the same time, and the violent explosion shattered all the qiē inside and there was no possibility of repair.

"Get out of here now and look for the real people of the space project!"

Ouyang Yu took back the vampire special forces, and Ingrid and the others disappeared into the air again, and in less than a minute, a large number of soldiers arrived, but what was left for them was a messy scene, and the officer who led the team angrily stomped his feet.

Ouyang Yu, the internal network of the Tongguò Research Institute, learned that the culprit that caused Tianyu Yayin's mother and daughter to come to this world was a space research project team of the Hod Empire, and what was obtained outside of this research group, so every time it was realized, it would always be connected to the earth of various parallel worlds, and Ouyang Yu needed to find or destroy that thing, kill the main leaders of the research group, and prevent the magic grasp of the Hod Empire from reaching the earth of various parallel worlds.
