.

Crack! The tall and heavy metal door slowly started and completely shrank into the stone wall. The scene behind the door was completely presented to Lei Jingtian's eyes under the light.

He almost squirted out blood. The scene behind the door was the same as when he came, with almost no change. He walked forward in the underground passage for about four hours, and seemed to have returned to the origin.

Lei Jingtian couldn't help but sigh, looked at the box of loss held in his left hand and murmured: "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 should do?" He patted McDull who was standing on his shoulder helplessly and asked, "Go back, or continue walking?"

McDull, who had just tried his best to get the metal door, could answer such a question? He just blinked at Lei Jingtian with his big confused eyes, not understanding how to respond.

Seeing its cute appearance, Lei Jingtian's depression dissipated a lot. In fact, once he made up his mind, he would never look back unless there was really no hope.

keep going!

A man walked forward in the deep underground passage, with the side and the side, except for a pet who could not speak, there were only fragments of stones, abandoned tools and endless darkness.

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

After moving forward for another two hours, Lei Jingtian saw the second door.

The door is open, and it is still a passage!

It was 3,500 meters deep underground, and the travel time was 8 hours and 37 minutes, and the third door appeared!

If it were someone else, I'd probably give up. The routes on the electronic map were densely packed and almost impossible to figure out, even if it took only more time to return to the ground according to the route.

However, opportunities often belong to those who can wait patiently

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

If ordinary people walk on the same road for 8 or 9 hours in a row, they will definitely be very tired in body and mind. Food and medicine can be used to maintain physical strength in the game. However, mental fatigue will definitely not be compensated without a long rest. The two doors opened in front are the same result. I guess most people don’t have much vigilance at this time.

However, Lei Jingtian is not one of the vast majority of people. An excellent sniper would not be able to succeed without tough nerves and firm will. So when three red lights swept over, he took a few steps back in the shortest time, almost "floating" a few meters away. He barely avoided the attack!

The mine passage was illuminated by the light transmitted from the door, and Lei Jingtian could easily see his opponent clearly - three skeleton-shaped robots. They were about two meters tall, and the metal skeletons on their bodies were silver and very textured.

The robots were holding an energy sword more than one meter long in their right hands, and a translucent energy shield in their left hands. On the bare metal head, two electronic eyes emitting red light looked at Lei Jingtian coldly.

Tianxing t2000, level 75 intelligent combat robot!

After the sneak attack failed, the three Tianxing robots immediately launched a pursuit towards Lei Jingtian. Their movement speed was very fast. The energy swords in their hands were even more waving, and they drove with vague response and cooperation.

Bang!

A Tianxing robot had just jumped out a few meters away and was about to wave the energy sword in his hand to slash Lei Jingtian's head, but his head was instantly bombarded through a big hole, and fell directly to the ground with lightning flashing.

Lei Jingtian, who knocked down a robot, couldn't feel relaxed at all. Although he moved quickly to retreat, the other two robots were pressed up like maggots on the bones, and an energy sword was brushing against his shoulder and swept over.

The Thunder Dragon pistol magazine in Lei Jingtian's hand was cleared because of the roar of the Thunder Dragon. The mental bullet emitted by McDull who helped the battle was also blocked by the robot with an energy shield. In this case, he had no chance to change the magazine!

Back! Back! Back! Back! Back!

McDull, whose attack failed, flew back behind Lei Jingtian, and a thought power shield was released on him, blessing him with a layer of protection.

As soon as the mind power shield was formed, Lei Jingtian stopped retreating and rushed into the middle of the two robots with his head down!

His move was very bold, but it was just right for both the timing of choice and the use of pace and skills. He just cut in before the two energy swords came together!

Clang! The Fang Army stabbed the metal spine on the neck of a robot, and a series of electric sparks suddenly burst into pieces.

Completeness is 96.4%!

The all-metal Earth and Heavenly Walking machine has a high physical defense ability, while the Lei Jingtian and Earth Swords are not attacking, so the damage it can cause is very small. However, Lei Jingtian did not expect to solve the problem in just a few seconds. He almost pressed the robot tightly and shook left and right around it. Relying on the high-aware speed and extraordinary reaction ability, he fought with it in close combat. The military spear in his hand stabbed it one after another, looking for a weak position in the vital and weak position.

Although it is a skeleton-shaped robot, the Tianxing robot is still quite tall. With the sword and shield in his hand, he was completely restrained when he encountered Lei Jingtian!

As an ordinary-level mechanical monster, the weakness of A's low is undoubtedly exposed at this moment. It only uses the energy sword in its hand to cut Lei Jingtian, but does not give up the energy shield in its left hand. As a result, it has caused mutual obstacles to attack, and being tricked by Lei Jingtian is simply a mess.

Another robot was even more unbearable. The attack it launched not only did not cause damage to Lei Jingtian, but instead frequently hit its companions, and even helped Lei Jingtian!

Like a very slippery loach, Lei Jingtian wandered between two robots, using the military spear in his hands to wear out their integrity bit by bit without mercy.

McDull, who was standing by, also found an opportunity and spit out a few thought-force bullets from time to time to help. Once the robot attempts to counterattack it, it will immediately slip away, which is shameless.

Under the lewd technique of one person and one pet, the two Sky Walk robots persevered for a few minutes and fell down one by one, scattered into piles of parts on the ground.

"It's just that I'm stingy!" Looking at the spoils of silver crystals on the ground, Lei Jingtian didn't even have the idea of ​​picking them up.

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

Standing on the passage and looking into the door, there is a completely different world inside!

It was a huge and strange space. From top to bottom, there was a silver metal column with a diameter of hundreds of meters. There were countless bridge passages between the column and the spiral-shaped staircase built on the surrounding walls. He could clearly see that there were many robots moving on the passages and stairs opposite.

Countless spotlights are embedded on the walls, and the bright light shines the entire space as if it is in the open sky of the sun.

Some are transporting supplies, while others are fully armed guards, showing a busy scene.

This is the science and technology laboratory of prehistoric civilization? It seems that he finally found the right place. Lei Jingtian carefully took a step forward, poked his head out and swept it around quickly.

He immediately found that on the metal staircase about 30 meters away, a group of Tianxing robots like before were rumbled towards him!

It was obvious that his intrusion had triggered the laboratory's defense system. Lei Jingtian took out the box of Lost and looked at it. The direction indicated was exactly the lower right!

It was exactly what he was afraid of! Lei Jingtian couldn't help but cursed, but he had no room to retreat when he got here.

A man jumped from the passage and jumped directly to the stairs facing the five or six Tianxing robots rushing over. With his thoughts, he was already in control of the endless thunder.

Bang!

The shock shooting started! A shock wave bullet instantly hit a robot. Under the violent impact, the shell was split into pieces, and the energy contained inside burst out violently, forming a strong shock wave!

The Tianxing robots who rushed towards Lei Jingtian immediately began to slow down, and they started to sway like drunkenness. Four of them fell to the ground with trembling and tripped the other two robots.

This result was completely beyond Lei Jingtian's expectations, but it was also a god-given opportunity. He rushed forward without thinking.

The rotational staircase is very wide, so these robots cannot block his way. They can easily break through the past with his speed. They jumped lightly over a robot's twitching metal thigh, Lei Jingtian cut the sniper rifle back into the gun box. He stretched his backhand and took out one of his secret magic weapons from his backpack---information jammer.

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