There was no trace of a battle in the huge research institute. However, Chang Fei looked as if he was facing a great enemy. He whispered to the three of them, "Shadow spies can transform into anything. They can even imitate mud, stone, and metal to launch sneak attacks. The guards are all dead. I guess they are besieging the reference room. Follow me."
After passing through the periphery, they came to the core area. Unlike the noisy explosions on the city streets, it was much quieter here. There was a faint mist in the air, which severely reduced their field of vision. The air pressure seemed to have changed. It was as if they were in water, which made them very uncomfortable.
"Hehe …" There was a burst of gloomy laughter in the mist. It was sharp, harsh, and unpleasant to the ears.
Shadow spies, as their name suggested, were not good at fighting head-on. They were good at disguising and sneaking attacks.
A group of strange men and women appeared from the mist. They had lost all their human characteristics. They used all four limbs like slender hounds, roaring and rushing toward the four of them.
Chang Fei hurriedly reminded them, "They are geno puppets controlled by shadow spies. Be careful. They are highly toxic. Don't get hit by their body fluids."
The four of them fought back. These humanoid puppets were very weak. They were all killed in a short time. As for the poison, it was impossible for people with strong sensing abilities like them to get infected.
At this time, shadows appeared in the mist again. There were neat footsteps, as if something heavy was gathering. Soon, robots with guns appeared in the mist and approached them.
"They are the defense robots of the research institute. They are also controlled by shadow spies. The weakness of these robots is the back of their necks. Aim at their necks and shoot."
Chang Fei once again displayed the powerful sword technique that alternated between illusion and reality. He was the first to attack. The robots that appeared this time were much stronger. They had extremely advanced combat programs. They were good at close combat, medium, and long-range shooting. Together with their invulnerable materials, they were really difficult to deal with.
Fujii Mingye smiled coldly. His skin lit up with a metallic luster. He picked up the short sword at his waist and rushed directly into the robots.
These people were all at the God level outside. After entering the Matrix World, their strength was greatly suppressed. However, they did not lose the understanding of the way of cultivation brought by their long lifespan. They all had a way to quickly improve themselves in a short time.
Fujii Mingye's cultivation method could make his body extremely hard. No matter what kind of attack hit his body, it would only produce sparks, but it couldn't pierce through. He only defended and didn't attack. He blocked a group of robots by himself.
Nan Feng casually picked up a long saber from the ground and rushed over. The heads of the machines around him were sent flying. He was like a tiger charging into a pack of wolves, instantly killing a few of them. She was a god created by an AI program. Her combat methods were focused on simplicity and efficiency. She did not have any specific combat methods. As long as she was fast enough and had a good angle, she would be fine.
Chang Fei's eyes shone even brighter. He had seen Luo Kai's swordsmanship kill the shadow spy in one strike and thought that Luo Kai was the strongest. He did not expect that the other two were not weak either.
Luo Kai also attacked with the real silver holy sword in his hand. With this kind of magical weapon in hand, everything could be broken. He did not need to find any weaknesses at all. Under the flash of the silver sword, no one could withstand a single blow.
This group of robot guards would be more troublesome for the Holy Disciples. However, with Luo Kai and the other two, it was extremely simple. Fujii Mingye relied on his improved physique that made him invulnerable. Nan Feng shuttled through the robots like a butterfly. Every time she waved her saber, a head would fly. No attack could hit her. For them, no matter how many robots there were, they were no threat.
After a while, this group of robot guards was killed. However, the four of them still did not dare to relax. They were even a little confused. They had already reached the interior of the Research Institute, but they still did not see anyone. Had they all been killed?
However, they did not see any corpses.
As they walked, Luo Kai's expression suddenly changed. He suddenly felt a sense of danger. There was no time to think too much. He stabbed his sword into the fog that was getting thicker and thicker. With a loud bang, his body had already been hit by the shock and was forced to take a few steps back.
Before he had time to see what the thing that attacked him was, he heard another "poof". Then there was another muffled groan. Chang Fei's shoulder, who was beside him, was already dripping with blood.
The two of them were attacked almost at the same time. Nan Feng reacted. Her face was as cold as frost. She raised her palm and pulled and twisted it. A red flow of energy appeared out of thin air and attacked the fog with layers of heat waves.
There was a loud bang in the darkness. Eh … Then there was a sharp and thin cry of surprise.
The four of them saw the sharp weapon that attacked them. It was a dark short sword that was about a foot long.
The short sword flew around the crowd and then disappeared into the darkness.
A clear voice came from the darkness. "Are you humans or foreign species?"
A woman in a grey Yin Yang robe appeared in the fog. Only the high-level Saints of the Taixuan Dojo could wear this kind of clothing.
Chang Fei held his shoulder. His face was originally gloomy. However, after seeing the woman's appearance, he hurriedly bowed and replied, "We are humans. May I ask who you are?"
The woman looked at the four of them and her expression softened. "I am Li Qian. I am a teacher of the Taixuan Dojo's Sacred Hall of Reason. Have you seen a young lady with a five-pointed star birthmark on her cheek?"
Chang Fei thought for a while and shook his head blankly. "No."
Luo Kai's expression changed. He hesitated and did not reply. This woman was looking for Xuan Xuan, the future Nightmare Demon God.
The woman was a little disappointed. Then she went to other places in the city. She did not care that the research institute was under siege.
Chang Fei wanted to ask her to stay, but seeing this, he could only give up.
The fog gathered in the research institute was getting thicker and thicker. It made people feel as if they were in water. However, no more enemies appeared. The mastermind seemed to know that he could not deal with the four of them and had retreated.
Chang Fei led them carefully through a building and came to the entrance of a building that extended into the underground. He pushed open the alloy door that was almost a meter thick. After passing through a winding underground passage, they came to a room. He took out a key and opened the alloy door that was almost a meter thick. The room was filled with stones of various colors. An iceman youth with skin so white that it was almost transparent sat among the stones. There was also an unknown black beast in his arms.
After seeing who it was, the youth in the room was relieved. "Why did the Cultivation Dojo only send three people?"
Chang Fei shook his head and sighed. "The Cultivation Dojo has been destroyed. The Zergs of the universe have attacked. Now there is a mess everywhere. There is no way to contact the high-level Saints. However, these friends are very strong. They should be able to help us."
Then he introduced them to Luo Kai and the others. "This is Alunsoro, a teacher of our research institute."
Luo Kai nodded and turned his gaze to the stones in the room. Nan Feng and Fujii Mingye had already walked over and studied them carefully.
What was carved on the stones were divine patterns. It was a kind of language similar to the book that Luo Kai had obtained that recorded the Five Thunder Technique. This kind of language had already broken away from the concept of the physical form of words. It was more like an expression of a kind of charm. In other words, whether one could understand it depended on one's level of understanding of the laws of the universe.
