Coming back from the surface, the second stop was the lift in the makeshift camp. The power supply of the lift is normal and can be used. Luo Ling took the lead again, vertically 350 meters underground, as an elevator, this number is quite strong, even exceeding the height of the old American Empire State Building.

At the other end of the elevator, there is a two-meter-wide and three-meter-high passage, which is completely made of rocks, and the workmanship is relatively rough, and it is repaired like an ancient fortress passage. The passage is long and deep, and it is a ladder road, the slope is not small, it has been like a downward curved extension, every 30 meters, there is an energy-saving lamp on the top, the road is gloomy, some sections are still dripping and seeping, wet and shining, making people feel very uncomfortable.

After walking for about a thousand meters, the way was blocked, the alloy door was opened from the other side, Ren Zhengzhi judged, with the existing tools at hand, if you want to open this door, it will take half a month. It seems that this passage is really used for escape from the underground research base. This indirectly proves that there must be a lot of dangerous monster research projects in the underground research base, otherwise, there would be no need for this.

Judging from the newly drawn electronic map, this passage is indeed leading to the underground research base, and it is directly to the Extreme Secret Research Institute, but according to the distance estimate, it is only a third of the way at most, that is to say, according to normal logic, there will be two doors ahead, one is the camouflage door of the Extreme Secret Research Institute, and the other is probably exactly the same as this one.

It takes a month to open the door, no one will choose this stupid method, this channel, give up for the time being.

The third stop is the exit of the test subject. This time, because it involves a possible battle, Han Xiaolu was added to the team.

The alloy door at the exit of the test subject does not open and close directly to the left and right, but first moves downward, then opens and closes left and right, and retreats into the door slots on both sides. This kind of structure involves a number of equipment such as levers and gears, and it can be said that under this room, there is a rather large mechanical frame.

Of course, Ren Zhengcheng and Fu Feng were not stupid enough to directly compete with those two iron lumps, they chose to dig down from both sides of the door, directly dig out a part of the mechanical frame, and then open the frame shell, from the struts, push rods, hydraulic rods, and screw rods that control the alloy door door switch...... Start and open the door. This kind of project must be overstretched for two people, so four soldiers were transferred to serve as temporary migrant workers for digging and transporting earth, anyway, these people are strong enough to do the work like a small forklift, and the speed is quite fast.

It was about seven o'clock in the evening, the work was done, and Ren Zhengzhi and Fu Feng cut off the spiral power lever that controlled the alloy door. This also means that if you want to open the door again, either reconnect the spiral power rod, or manually twist the upper part of the spiral power rod to achieve the purpose of opening.

Ren Zhengzhi, who had a sense of accomplishment, said: "I really hope that a batch of test subjects will be sent below, you think, the screw rods on both sides are idling, the door is not actually opened, and the underground elevator platform is pushed up, what do you say the monster will look like?" ”

"Meatloaf? Specimen? It depends on whether they are smart enough, and if they are smart enough, at least three of them can escape into the shadow plane. Fu Feng said.

"Curse them, they're stupid!" Ren Zheng smiled.

The problem of the subject's exit was solved, and people were not in a hurry to continue the expedition, but went back to have a good meal, a good rest, and everything was discussed tomorrow.

On the seventh day that Luo Ling and the others left the Anshun Street base, after enough sleep and rest, the people of the Holy Seal Knights had basically recovered their combat strength. Most of the minor injuries have been scarred and healed, and the slightly more serious ones have recovered half of the Tai half, and the two seriously injured ones are gradually getting better, even if they return to the base, the early treatment is similar to this, and their injuries heal, more of which takes time.

Everyone got up very early today, ten people, including Luo Ling, this is a reinforcement group, ready to explore the exit of the test subject. According to some people's hopes, it is quite possible to go directly to the interior of the underground research base through this exit.

The alloy door was opened, and below was a two-meter-square shaft passage, with a metal frame and concrete structure, as if it were an abyss leading to hell.

Push, shake, and let go, a fluorescent ball is thrown down, not only for illumination, but also for measuring depth.

The bright fluorescent ball grew smaller all the way, and finally, when it became a faint bright spot the size of a pinpoint, it stopped moving. Fu Feng of the instrument gave the data: "600 meters vertically, better than that single lift!" ”

"! There is no gear track on both sides, this platform seems to be the most clumsy screw push-up type, if you want to push up 600 meters, then there should be 600 meters of screw telescopic space below, and the length of the lifting platform is not more than 1200 meters? What kind of cow is this guy in charge of building this kind of Big Mac-style thing? Ren Zheng scolded.

"It is estimated that the money to repair this elevator is enough for three generations of ordinary people's ancestors and grandchildren!" Li Xiao also helped.

"Money! Money! You're about to become Song Yizhou's second! Xing Juan was also one of the participants in the operation.

"How?" Luo Ling asked, at a depth of 600 meters, I'm afraid no one would prepare such a long rope.

"It can only come one by one!" Ren Zhengcheng sighed.

The so-called section by section is like climbing a cliff, every 30 meters a pair of hooks and loops are nailed into the side wall, and then continue down 30 meters, and then a pair of hooks and loops, two pairs of hooks and loops are double insurance, in case one is loose, there is another can work.

Hooks and loops are generally not brought by scientific and technological sappers, and when needed, they are made from local materials and freshly made. They have quite small craft tables, and it's very difficult to make weapons out of them, but it's no problem to tinker with weapons and equipment, make a prop, or something. Aren't there a lot of wrenches, toolboxes, and other iron tools in the access tunnel? Melt it, make a hook and loop.

Luo Ling watched it with relish on the side, "Hmm! The profession of science and technology sapper is really a very good auxiliary profession, and with them, many places can save a lot of effort. It is really able to go to the sky and the sea, and it is a facility and tool left by human beings before, and it can be used by them. Yes, yes, go back and study it, only to know that brute force is obviously not in line with the trend of the times! ”

Finally, finally, when I went down to the bottom of the shaft passage, a side door blocked the way, wasn't it just a 10CM homogeneous steel plate? Kill it and move forward! The light is coming!

Inside, dumbfounded, behind the door is a 5-meter square metal house, empty, only on the opposite side of the door there are three parallel pipe holes in the style of sewage pipes, the pipe holes are still sealed by the gate.

With an ominous premonition, Ren Zheng measured it straightly, and then said with a dejected face: "The lower closed jack gate, the thickness is more perverted than the one in the escape passage, this is where the test subject comes out, lying down, and the conveyor belt is sent out!" ”

Luo Ling was speechless, this thing was designed by people to be really strong regardless of the cost, and almost eliminated all possibilities except for tunnel entry. I don't know if it's to defend the inside or the outside, maybe it's all against it!

After a lot of twists and turns, but in vain, Ren Zhengcheng and Fu Feng did not give up, and when they left, they not only destroyed the lifting platform, but also arranged a lot of insidious mines in the entrance and exit rooms of the experimental subject.

After a long day of still going through the tunnel, everyone was in a bad mood, and they all held back the fire in their stomachs, returned to the temporary camp to rest for an afternoon, had dinner, packed up, shook their spirits, and marched towards the tunnel again.

This time, the lineup is relatively strong, Luo Ling and Qin Qing have 8 people on their side, and Xuanyuan Leiluo has 9 people on their side, except for the 3 people who are seriously injured, have not recovered from their injuries and are responsible for staying behind, they can be described as elite.

Before they reached the underground warehouse, Ren Zhengcheng and Fu Feng reported that part of the thunder placed at the entrance and exit of the test subject exploded.

"It's getting more and more like an autonomous defense system! As soon as you cross the line, it's weird! Han Xiaolu said.

Everyone also felt the same way, and Xuanyuan Leiluo connected to the temporary camp and asked him to pay close attention to the movement in the direction of the entrance and exit, and report any abnormal movement immediately.

The action group moved on.

Before coming to the large cargo elevator in the underground warehouse, Luo Ling made a decision, "There are monsters wandering on the tunnel platform below, but the danger is not great." ”

The elevator was repaired and used, and all 17 people were lowered at one time, one by one, just like the POSS action at the end of the Spring Festival Gala dance, the posture was opened, and after sufficient preparations, they were ready to kill.

Hearing the elevator move, as a greeting salute, a live hanging corpse threw out a black hole ball at the right time.

Bang bang bang! Luo Ling's sniper spear was fired, and the live hanging corpse was too late to control the black hole ball, and while drifting back, he kept using the space fault to protect himself. The platform was large enough, and the rest of the people took the opportunity to avoid the range of the black hole ball. Eventually, the black hole ball hit the wall, 'gnawed' a big hole in the wall, and disappeared without a trace.

The long-range attacks in the team were all activated, and now, the living hanging corpses that had not yet floated to a safe range couldn't stand it, and when the old shield had weakened and the new shield was not alive, Luo Ling shot him in the center of the eyebrows, and the back of his head exploded, and the crooked dial of hell flew out with a clang, and the body full of fluorescent viscosity was like a broken sandbag, poof! Fell to the ground and turned into a puddle of nausea.

"Wait! Don't go any further! Luo Ling stopped everyone's forward movements.

"The living hanged corpse is overconfident in its own defenses, and wants to retreat as an advance to calculate us." Luo Ling said to Ren Zhengzhi and Fu Feng: "Can you let the robot lay mines near 10 meters to the right of the fifth pillar in front?" ”

"No problem!" Ren Zhengcheng and Fu Feng replied.

"Good! There are monsters hidden there, and it should be a nest of tyrants. ”

Hearing Luo Ling say this, people naturally knew what to do, the two robots levitated over, throwing down several mines, and the other snipers, scientific and technological engineers, and sorcerers were all ready. Then, the two Phantom Warriors walked forward, entered the monster perception circle, waited for the five rays to flash on the ground, and then quickly ran back.

Oh! The Tyrant Flogger led a group of younger brothers out. What awaits them is the baptism of continuous explosions and long-range firepower, and the death is not miserable, it is estimated that they didn't understand what was going on, and they met their demon ancestors.

Xuanyuan Leiluo, who was standing behind, and the two masters glanced at each other, and they both felt the helplessness of the other party. The advantage of anticipating the enemy's opportunity is that it is extraordinary, and if the monsters want to ambush, they can only dig a good grave for themselves.

Refining materials, the skin and claws of the tyrant and the scales are good things, the armor, horns, and whips of the tyrant whipper are even better things, the skin of the live hanging corpse and the viscous internal organs are also useful, that is, the metal chisel pierced on the body, which are all quite good magic materials, and the most valuable is the hell dial, which can greatly improve the collection and output speed of magic energy, and it is quite versatile.

After prior discussion, from this moment on, all the material harvest was divided into three points, one for the Holy Seal, one for Qin Qing's Thunder Fire Detachment, and one for Luo Ling. Luo Ling didn't have to do anything, naturally someone was specifically responsible for extracting materials.
