The fat researcher wiped the sweat off his face, and the flesh above his chin was trembling:

"Sir! This was handed over by the combat department a day ago. It should have been snatched from the transport convoy of the Violent Hunting Group. According to the intelligence personnel at the front, this thing was also snatched from the Bilmark Empire test site by the Violent Hunting Group. Because this machine should be consistent with the content of our laboratory, it was sent to us for cracking."

"No wonder it's like this..." Du Yuqi suddenly thought of this sentence, and then he thought:

"So, have you achieved any results?"

The fat researcher said:

"According to our preliminary analysis, this machine is quite important. It is a decoding machine responsible for deciphering and encrypting various secret intelligence and messages. Because its operating principle is different from the technology we use, we have not yet been able to analyze its specific operating methods."

Du Yuqi was very interested in the Demon City, not only because his strength had improved by leaps and bounds there, but also because he felt that there were many unsolved mysteries in that place, so he immediately asked:

"So what did you analyze?"

The fat researcher said honestly:

"We have only figured out its operating mode so far, and have obtained some information using the data disk we obtained, but the data we have interpreted is quite ordinary."

Du Yuqi was waiting at this time, so he said:

"Show me the operation."

The fat researcher then operated it obediently. When Du Yuqi saw the data disk that this guy took out, his heart skipped a beat, because the data disk he took out was only the size of a fingernail, and its appearance was exactly the same as the crystal chip on his body. This crystal chip was treasured in the lighthouse of the demon Ios together with Kahn's mutant Terra Stone!

Du Yuqi remained calm and watched the fat researcher perform the operation. He found that the operation process was extremely simple. He just stuffed the chip into the entrance of the machine and pressed a start button. The machine began to automatically decode and display information. Press the start button again and the chip will be spit out.

However, Du Yuqi had already hidden his crystal chip and was not around, so he signaled Jet to take the decoder away. Jet said he liked this kind of robbery the most, and started packing without saying a word. The people around him wanted to stop him, but they were too embarrassed to cry.

After a short delay, the replica had completed the activation procedure, was successfully activated, and stepped out of the incubator.

This is a two-headed dog with a very ferocious appearance. Its body is covered with pangolin-like scales. It is said to have very good performance in magic resistance and physical resistance. Although its four legs are very slender, its explosive power is amazing. Of course, the focus lies on its two heads. The icy head on the left can spit out amazing cold air that can freeze the enemy, while the head on the right can spit out blazing flames.

The mother cell of this clone comes from the three-headed hellhound in the "top secret area", while the head that spews cold air is implanted with the ability of the Bantu female warrior: ice breath attack, and the head that spews fire is implanted with the ability of the monster that escaped from the city of Bakkar: the red dragon Kimon.

Therefore, the highlight of this experimental subject when it was designed is the double-headed ice and fire attack. To be more precise, it uses ice breath to significantly slow down the enemy, and then the fire breath after charging can successfully hit the enemy and perfectly KO the enemy.

At this point, the attack power of this guy has already satisfied the higher-ups. What needs to be solved is the problem of the body's balance. The implanted cells always show rejection and are incompatible with the mother's body. Their survival period is only one day at most, so it is difficult to mass-produce them on a large scale in actual combat.

After Du Yuqi obtained the authority to control the experimental subject, he strode towards the passage next to it. Whenever he came to a fork in the road, Du Yuqi would stop to carefully identify the path with a serious expression. Finally, he broke into several rooms in succession and stopped in one place. After he stopped, both Xi and Jet looked at him strangely, because this was - the bathroom.

At this time, Du Yuqi and his team had already wasted a lot of time in obtaining the experimental subjects, and they were racing against time. Both Xi and Jet must be a little anxious, wondering what Du Yuqi's intention was in coming to this place.

At this time, Du Yuqi half-knelt on the ground, and then used the alloy steel broken stick in his hand to pry the steel plate of the bathroom drain. Jet was already shocked:

"Are we going to drill into the sewer pipes?"

After Du Yuqi pried open the steel plate of the bathroom drain, a long pipe slanting downward was revealed. Although the pipe looked quite large, it was estimated that only a baby could crawl in it. There was also a strange smell mixed with the smell of shampoo, which was definitely unpleasant.

Then Du Yuqi stomped his foot down!

His strength at this moment could be said to far exceed that of ordinary people. After he stomped his foot down, the pipe below immediately made a teeth-grinding creaking sound, followed by a loud bang as the bolts were violently broken and twisted, and fell off cleanly.

At this time, Du Yuqi kicked a few more times to completely expand the drain of the bathroom, and then jumped down first. Because the pipe below had been kicked down, he actually entered the room on the next floor when he fell this time.

This cabin is quite spacious, probably at least 700 to 800 square meters, and its shape is also quite peculiar, like a trapezoid with a piece cut off. The cabin is dirty and messy, emitting a very unpleasant smell, and there are a lot of messy things piled in a corner of the room.

As for what occupied most of the room, there were all kinds of pipes, some new, some old, some thick, some thin, which finally converged together to form an extremely thick pipe, whose diameter was almost as big as a bus compartment, which looked quite amazing. If we use a more appropriate statement, it was as if there was a big heart here, with many blood vessels converging from all directions. If we use a simple statement, this is a sewage pipe collection point...

After arriving in the cabin, Du Yuqi looked around and found a door on the giant sewage pipe:

"Yeah...it's true. The pipeline is so huge, so they must have considered the repair of the damage. Of course, they would leave a door for the maintenance workers to repair."

The door was obviously locked at this time, but such an obstacle was obviously not worth mentioning in front of Du Yuqi's strange strength. He kicked it open obediently. Du Yuqi tore off a piece of clothes to cover his face, walked in very straightforwardly, and explained:

"Don't worry. Although it's a little dirty in here, you don't have to worry about entering a cesspool-like environment, because the Isabella has a very complete biochemical circulation mechanism. All excrement is considered organic fertilizer and will be collected separately through special pipelines. For the Isabella, which may be flying in the air for a long time, these organic fertilizers are very useful. They can be fermented to generate fuels such as biogas. After generating fuel, it can be used as fertilizer to grow vegetables, mushrooms and other food crops, forming a perfect ecological chain."

After listening to Du Yuqi's words, Jet walked in doubtfully and found that the smell inside was definitely bad, but the strongest and most pungent was the chemical waste gas. At the bottom of the pipe, sewage was constantly flowing, forming a stream. In addition to sewage, there were also a lot of things like stones, scrap metal scraps, etc. Otherwise, there would be no need for such a large pipe just for sewage discharge.

The three of them could only walk on both sides of the pipe. After they got used to the darkness inside, they quickly ran forward under the leadership of Du Yuqi.

After running for about dozens of meters, they suddenly heard a series of rapid sounds of "dangdangdangdangdang" coming from the darkness, as if dozens of people were knocking on a metal pipe with small hammers. Xi immediately fired a mind cannon, which instantly illuminated the darkness deep in the pipe. He found that there were more than a dozen monsters that looked like large mechanical spiders crawling towards them rapidly. The continuous and rapid sounds of "dangdangdangdang" were the sounds made by the eight legs of these large mechanical spiders crawling on the wall of the pipe.
