"If you don't get up yet, I'm leaving first!" Seeing that the situation was not good, Huang Xun checked his remaining 10% battery and flew away from Gao Fei's body.

The two small ruin monsters attacking Li Teng who were not yet dead also rushed towards Gao Fei who was lying on the ground.

It seems that there is some kind of connection between these small ruins monsters and the giant ruins monster, and they know some simple tactical coordination. When the giant ruins monster attacked Li Teng, they helped to besiege Li Teng. Now the giant ruins monster

The ruins monsters changed their attack targets, and they also changed their attack targets.

Li Teng felt that the situation was not good, and after getting up, he ignored the pain in his body and picked up a metal bone claw of a small ruin monster from the ground. He quickly climbed onto the arm blade of the giant ruin monster just as it was raised.

, and then followed the force of raising the arm sword to rush forward and jump quickly.

At the moment when the giant ruin monster's arm sword was fully raised, he jumped forward and jumped into the hole opened by the grenade behind the giant ruin monster's eyeball.

Then he pointed the metal bone tip in his hand at the hollow circuit board, and the biochemical tissue was destroyed violently and wantonly.

The giant ruin monster raised its machete high and was about to strike at Gao Fei who was slowly getting up under the ground and had no time to escape. Suddenly his huge eyes froze and his body froze in place.

The two small ruin monsters that were charging forward crazily seemed to have been affected by something at this time, and they stopped together.

Then, the huge body of the giant ruin monster suddenly fell down and hit the two small ruin monsters, instantly crushing them into pieces of flesh and metal.

The ground trembled, and a mushroom cloud of dust rose.

Some nearby buildings that had not completely collapsed before also completely collapsed at this time.

Li Teng staggered out of the dust and smoke. His clothes were in tatters and bleeding from several wounds. Gao Fei slowly got up from the ground, faced Li Teng, and put his clothes on Li Teng's body.

Huang Xun quickly buzzed back and hung himself on Gao Fei's ammunition box.

Liu Hui, who was parked two kilometers away, quietly drove back when she heard the huge explosion and the smoke rising into the sky.

I happened to meet Li Teng walking through the dust and smoke.

Of course there are Gao Fei and Huang Xun.

Li Teng had many injuries on his body. Fortunately, there were no fractures, but the three external injuries were also shocking.

Especially the wound on the thigh was more than ten minutes long and two centimeters deep, and the muscles were turned up.

Although there is no medical cabin on the train, there are some anti-inflammatory drugs, bandages, sutures, etc.

But the most serious injuries were not these three external injuries.

His head suffered severe concussions and impacts when the grenade exploded and when the giant ruin monster fell, causing him to suffer from concussion symptoms.

Li Tengqiang allowed Aisha to help him suture the three wounds one by one, then he lay on the bed and closed his eyes.

He didn't fall asleep, he was in a coma.

Anna lay next to him and tried to raise her head to look at Li Teng's injuries... This guy had obviously gone somewhere to die.

It's a pity that she can't do anything to help.

It's not easy for her to even raise her head now.

In this plot, it seems that she is either winning or losing. Anyway, she can only lie down.

I have never acted in such a depressing scene.

…

Twelve hours later, Liu Yin's engineering vehicle was upgraded from LV1 to LV2.

Although her body shape has not changed much, her two robotic arms are obviously much thicker.

The power reserve is doubled.

Her tracked rollers have been upgraded to be used as both wheels and tracks.

On the outside of the track rollers, four huge independently driven off-road tires are hung, which can be switched from crawler structure driving to tire driving at any time, allowing her to reach a speed of 80 kilometers per hour on some relatively stable surfaces.

In addition, her drill bits, electric saws, steel claws, buckets and other accessories have also been fully upgraded, and their power has increased by at least 50% compared to before.

After the upgrade, the engineering vehicle left the train and started cutting, and its work efficiency was obviously improved several times compared with before the upgrade.

The energy metal content of the giant ruin monster is very high, and the hardness is also very high. The engineering vehicle before the upgrade cannot cut energy metal with this hardness at all. The upgraded electric saw has added the energy cutting function, and the energy carried by the saw blade

It can make the temperature at the cutting edge reach more than 2,000 degrees.

Although the main task of the engineering vehicle is still work, it also has considerable combat effectiveness.

After encountering the small ruins monster before, in a one-on-one situation, you will not be as helpless as before.

The energy metal is cut and transported back one time at a time.

Liu Hui devoured these energy metals with big mouthfuls.

The energy level of the train's digestive system that has been upgraded to LV2 has also been greatly improved. It can quickly melt the collected energy metals, remove the waste residue inside, and store useful energy and metals for train upgrades.

Finally, after eating three-fifths of the giant ruin monster, Liu Hui stopped.

It's time for her to upgrade again, from LV2 to LV3.

If you want to continue eating these energy metals, you can only wait until you reach LV3.

It takes four hours to upgrade from LV2 to LV3.

Li Teng is now in a coma, but others think he is sleeping.

Daisy's injury did not worsen, so the team temporarily stayed with the corpse of the giant ruin monster.

Liu Hui wanted to wait until the upgrade was completed and eat all the corpses of the giant ruin monsters and the small ruin monsters before moving forward.

…

Another four hours passed, and the main train base was upgraded from LV2 to LV3.

At LV2, the train's exterior armor was two centimeters thick, and its anti-strike capability was equivalent to an eight-centimetre-thick steel plate.

After LV3, the quality of the train's exterior armor alloys has been greatly improved. Although it is still only two centimeters thick, its impact resistance is comparable to that of a sixteen centimeter thick steel plate.

The tire material of the train has also been fully upgraded. When the train is stationary, the protective panels can be put down to fully cover the tires.

The increase in weight also makes the train's chassis more stable, making it less likely to tip over in the event of an explosion or impact.

After the train upgrade was completed, Li Teng still didn't wake up. Liu Hui had no way to ask Li Teng for instructions, but she guessed that Li Teng would definitely give priority to upgrading the exoskeleton, so she decided to upgrade the exoskeleton again, preparing to upgrade the exoskeleton from LV2.

to LV3.

After the upgrade is completed, the exoskeleton will become a complete set of armor covering the whole body.
Chapter completed!
