Liu Feng nodded: "So before blasting, we need to find a suitable location, use tools to make a cave, and then let the nearby people retreat into the cave when they came, and finally put the high-energy enchantment explosive in and detonate it."

The few people discussed for a while, but found no better way. They decided to try the method according to what Liu Feng said.

Scouts use instruments to detect, and then after careful calculations. [bsp;     "The classification of laboratory levels of this ancient civilization is from low to high to level one to level four. The value, function and function of the laboratory of different levels is different. The structure, facilities, various equipment and experimental topics of the first-level ancient civilization biological research laboratory are for some ordinary projects, such as the development of some ordinary bullets, weapons, etc. The second-level laboratory studies some scientific research projects with certain difficulty, such as mecha firepower systems, and various mechanical systems. The third-level laboratory is an advanced version of the second-level laboratory, mainly responsible for more sophisticated robots, mechas, and science and technology research. The highest-level fourth-level laboratory conducts some top-secret experiments, which are not something that ordinary people can know. Every fourth-level ancient civilization laboratory has extremely high value, and even those general-level figures will be moved."

The scout collected relevant information and said, "Based on the combat power of the black iron bulls, the golden armored scorpions just now and the technology they represent, the hidden laboratory here is likely to be a level 2 laboratory. There should be a data storage system inside. The construction of level 1 and level 2 laboratories is much simpler than that of level 3 and 4. According to the structure built by conventional laboratories, the success rate of blasting from here is greater."

As he said that, he used chalk to mark an area on the ground. The scout obviously knew that it was of great importance and added: "Of course, I am only 60% sure. After all, the size of the underground laboratory may not be exactly the same as the area on the ground."

Yanshan used a heavy sword to chisel a pit three feet in a radius but three meters deep.

Liu Feng fixed all the collected high-energy enchantment explosives and let the rest of the heads retreat back to the cave when he came.

High-energy enchanted explosives are brought by Meng Qian's men. This explosive is ten times more powerful than ordinary explosives and three times more powerful. It is used for blasting special buildings and shells for the creation of enchanted mortars.

Liu Feng retreated a hundred meters away, rubbed his right hand suddenly, and accurately hit the explosive fuse. With a loud bang, everyone felt the blackness in front of them, and the huge wave of air suddenly rushed into the cave, causing the people at the entrance to fall backwards involuntarily.

The smoke dissipated, and an irregular hole three feet wide appeared at the location where the explosives were placed.

"Success!" The scout took the telescope and shouted excitedly.

A row of consoles in the underground laboratory have been blown up. In addition, only three super-large computers in the laboratory with hundreds of storage are still flashing, but they also emit an alarm of insufficient power.

Under Meng Qian's instruction, the scouts nervously operated the giant computer and used various instruments to decrypt.

"Tip~Tip~ Five minutes left, Laboratory q8 will enter the self-destruction program due to insufficient power. At that time, all the data of Laboratory q8 will be transferred to Laboratory q9, which is 300 meters underground." A somewhat harsh alarm sounded.

"How long will it take to crack the password?" Meng Qian asked anxiously.

"Four minutes!" Slight sweat beads emerged from the scout's forehead.

The laboratory was about to explode in five minutes, and everyone had to leave at least ten seconds as time for escape, leaving only a few dozen seconds for him to collect samples.

The harsh countdown echoed in his ears, and the good psychological quality he had developed for a long time made his hands that controlled the instrument still stable.

"There is less than a minute left, and everyone else will withdraw!" Liu Feng looked at the time. In order to prevent accidents, he made a quick decision and decided to withdraw the rest of the people from the laboratory first to avoid unintentional disasters.

Fifty-seven seconds later, Liu Feng rushed out of the underground laboratory with his scouts, like a cheetah running wildly, and quickly drilled into the nearest cave passage.

Huge flames chased him, burning all the rocks at the entrance of the cave for three meters deep. Fortunately, the entrance of the cave was not big, and the flames rushed in were not fierce, and were blocked by the Falcon Armor.

"What happened?" A slightly majestic voice rang.

Liu Feng poked his head out and saw a strange captain standing there in the distance, frowning. Meng Qian was telling him the situation. Of course, the words told the captain were all modified and processed.

Behind the captain, there are several adjutants with the rank of lieutenants. The investigation lineup sent by the headquarters is much stronger, and it is obvious that they still attach enough importance to this ruin.

"What? You actually exploded this laboratory? The headquarters sent me to excavate this ancient civilization ruin, but you deliberately made trouble for me. Lieutenant Meng Qian, can you bear this responsibility?" the captain roared angrily.

"Captain Jiming, I think you should be clear about some rules of the headquarters. Any ruins and those who report the headquarters are qualified to explore in advance before the arrival of the headquarters. In order to explore this place, our team killed three excellent soldiers, and many others were injured. They paid such a great price, but they did not gain any benefits. Unexpectedly, you not only did not forgive us, but instead blamed us." Meng Qian countered coldly.

"You are not exploring! It's destruction! Do you understand destruction?" the captain named Jiming shouted in anger.

"What this blows up is just an irrelevant affiliated laboratory. The real secret is in the Q9 laboratory deeper underground. Whether it can be detected depends on your ability." Meng Qian said a word and asked Liu Feng and others to return the same way.

The captain heard that there was a deeper laboratory and his face looked a little better. Although he was still suspicious, he knew that the other party did not dare to lie on such a critical issue, and it was difficult to continue to obstruct it at the moment, so he let Meng Qian and others leave. He didn't know that with the explosion, the road to Q9 laboratory had been blocked long ago. He wanted to explore further unless he found a way to carry large-scale mechanical excavation tools in.

Leng Danrong seemed to have been impatient for a long time. Seeing Liu Feng, Meng Qian walked out and immediately came forward: "You are finally back. Wait for a while, I have to go crazy."

"Huh? Where are those slaves?" Meng Qian fiddled with her somewhat messy hair, glanced around and found that except for Qin Yu, who was still tied up there half-deadly, the rest of the slaves were gone.
