Click! The tall and heavy metal door slowly activated, completely retracting into the stone wall, and the scene behind the door was completely presented in the light of the thunderous eyes.

He almost spurted out a mouthful of blood, and behind the door it was still the same scene as when he came, almost unchanged, and after almost four hours of walking through the underground passage, it seemed to be back to square one.

Lei Jingtian couldn't help but sigh, looked at the lost box held in his left hand and muttered: "Boss, don't play with me, time is life, you are wasting my life!" ”

On the lid, the arrow points straight ahead.

"Hey baby, what do you think we're going to do?" He patted McDull standing on his shoulder a little helplessly and asked, "Go back, or keep walking?" ”

McDull, who had just tried his best to get the metal door, could answer such a question, but he just looked at Lei Jingtian with big confused eyes, not knowing how to respond.

Seeing its lovely appearance, the thunderous depression dissipated a lot, in fact, once he made up his mind, unless there was really no hope, he would never look back.

Keep moving!

A man walks through a deep underground passage, left and right with nothing but a non-talking pet, only fragments of rocks, discarded tools, and endless darkness.

Repeat and repeat, turn and turn, the road seems to never end.

After continuing to advance for another two hours, Thunder saw the second door.

The door opens, and it's still the passageway!

3,500 meters underground, with a travel time of 8 hours and 37 minutes, the third gate appeared!

If it were someone else, I'm afraid I would have given up a long time ago. The electronic map is so dense that it's almost impossible to figure out what to do, even if it takes more time to get back to the ground if you follow the route.

However, opportunities often belong to those who can be patient

The third door was opened by McDull, and this time it was finally no longer repeated and repeated, and the world in front of him lit up, and then three red beams of light flew towards him from different angles!

If the average person walks on the same road for 8 or 9 hours in a row, then the body and mind must be very tired, and the game can be used to maintain physical strength with food and medicine. But mental fatigue is certainly irreparable without a long rest. Opening two doors in front of you is the same result, and it is estimated that the vast majority of people do not have much vigilance at this time.

However, Lei Jingtian does not belong to one of the vast majority of people, a good sniper cannot succeed without tenacious nerves and firm will, so when the three red lights swept in, he took a few steps back in the shortest possible time, almost "floating" out a few meters away. Kankan dodged the attack!

The passage of the mine was illuminated by the light shining through the door, and it was easy for Thunder to see his opponent - it was three skeleton-shaped robots, they were about two meters tall, and the metal skeletons of their bodies were shiny and shiny.

These robots all held an energy sword more than a meter long in their right hands, and a translucent energy shield in their left hands.

Skywalker T2000, a 75-level intelligent combat robot!

After the sneak attack failed, the three Skywalker mechs immediately launched a pursuit of the thunderous sky, and they moved very fast. The energy sword in his hand was even more vigorous, and he faintly echoed and cooperated with each other.

Bang!

A Skywalker mechano had just jumped a few meters away, and was about to swing the energy sword in his hand to slash at the head of the thunderous sky, but his head was blasted through a big hole in an instant, and he fell directly to the ground in a flash of lightning.

The thunder that brought down a robot was not easy at all. Although he retreated quickly, two other mechs clung to him like maggots on tarsal bones, one of which grazed his shoulder.

The magazine of the Thunder Dragon pistol in Thunder Shock's hand was emptied because of the release of the Thunder Dragon's roar, and the telekinetic bullet sent by McDull who was helping in the battle was also blocked by the robot with an energy shield, and in this case, he had no chance to change the magazine at all!

Withdraw! Withdraw! Withdraw!

McDull, whose attack failed, flew back behind Thunder Shocking Sky first, and a telekinetic shield was released on his body, giving him a layer of protection.

As soon as the telekinetic shield was formed, the thunderbolt did not retreat, and he lowered his head and rushed sideways into the middle of the two mechs!

His move was very bold, but both the timing and the use of pace and skill were just right. Just in time to cut into it before the two energy swords came together!

Boom! The fanged army stabbed the metal spine of a robot's neck, and a flash of electric sparks erupted.

96.4% completeness!

The all-metal Skywalker mech has a high physical defense, while the Thunder Spike does not have a high attack power, so it can deal very little damage. However, Lei Jingtian did not expect to solve the problem in three or two clicks, he almost clinged to the robot, swaying left and right around it. Relying on its high speed and excellent reflexes, it fights closely. The military thorns in his hand stabbed at its body one after another, looking for the weak spots.

Although it is a skeletal type. However, the Skywalker Robot is still relatively tall, and with the sword and shield in his hand, he has been completely restrained in a tactical way of playing when he encounters Thunder Shocking!

As an ordinary-level mechanical monster, A's low weakness was undoubtedly exposed at this moment, it only used the energy sword in its hand to cut the thunder, but it did not give up the energy shield in its left hand, which caused mutual obstacles in the attack, and it was simply played by the thunder.

And the other robot was even more unbearable, not only did its attacks not bring damage to Thunder Shocking, but frequently hit its own companions, and actually helped Thunder Shocking!

Like a slippery loach, Thunder swam between the two robots, mercilessly wearing down their integrity with the thorns in their hands.

McDull on the side also found an opportunity, spit out a few telekinetic bullets from time to time to help, and once the robot tried to launch a counterattack on it, it immediately slipped away, which was shameless.

Under the rather lewd method of one person and one pet, the two Skywalker robots held on for a few minutes and then fell helplessly one by one, scattering into piles of parts on the ground.

"It's just stingy!" Looking at the few silver crystal trophies on the ground, Lei Zhentian didn't even have the idea of picking them up.

He switched his pistol again, loaded a new magazine, and returned to the metal door.

Standing on the passage and looking through the door, it's a whole different world!

It was a huge and strange space, and in the center of the space stood a silver metal pillar with a diameter of hundreds of meters, and countless bridges and passages were linked between the column and the spiral staircase built on the surrounding walls, and he could clearly see that there were many robots moving on the opposite side of the passages and stairs.

Countless spotlights are embedded in the walls, and the bright light illuminates the entire space as if it were in the open air.

Some were transporting supplies, others were heavily armed guards, showing a busy scene.

This is the scientific and technological laboratory of a prehistoric civilization? It seemed that he had finally found the right place, and Lei Jingtian took a step forward cautiously, poked his head out and quickly swept left and right.

He immediately noticed that on the metal staircase in the lower right position, about thirty meters away, there was a group of Skywalker robots that were rumbling towards him!

Obviously, his intrusion had triggered the laboratory's defense system, and Thunderbolt took out the Lost Box and looked at it, and the direction indicated happened to be the lower right!

It's what you're afraid of! Lei couldn't help but curse secretly, but he had no room to back down when he got here.

One jumped straight from the passage to the top of the stairs to face the five or six Skywalker robots rushing towards him, and in the flash of his mind, the endless thunder was already under control.

Bang!

Concussion Shot is launched! A shockwave bullet instantly hit a robot, and the shell was torn apart under the violent impact, and the energy contained in it burst wildly, forming a strong shockwave!

The sky-traveling robots that rushed towards the thunderous sky immediately began to slow down, swinging as if they were drunk, and four of them fell to the ground tremblingly, only to trip the other two robots.

This result was completely unexpected, but it was also a godsend, and he didn't want to rush forward.

The spiral staircase is very wide, so the mechs can't stand in his way, and with his speed he can easily break through the past. Jumping lightly over the still twitching metal thighs of a robot, Thunderbolt cut the sniper rifle back into the gun case, and backhanded it and took out one of his secret magic weapons, the information jammer, from his backpack.

In an environment full of mechanical monsters, the information jammer is an excellent special piece of equipment that can help Thunderbolt not be surrounded by more and more robots.

As soon as he pressed the button, the interference signal was sent out in a steady stream, and Lei Zhentian knew that he had little time, so he took out the lost box and looked at it as he ran.
