"If you don't get up yet, I'll go first!" Seeing that the situation was not good, Huang Xun checked his remaining ten percent of the battery, and flew away from Gao Fei's body with a buzz.

The two small ruin monsters that attacked Li Teng and were not dead here also rushed towards Gao Fei who fell to the ground at this time.

It seems that there seems to be some kind of connection between these small ruin monsters and the giant ruin monster, and they know how to play some simple tactical cooperation, when the giant ruin monster attacked Li Teng, they helped to besiege Li Teng together, and now the giant ruin monster has shifted its attack target, and they have also shifted the attack target together.

Li Teng felt that the situation was not good, and after getting up, he didn't care about the pain in his body, picked up a small ruin monster's metal bone claw from the ground, and quickly climbed on the arm knife while the arm knife of the giant ruin monster had just been raised, and then rushed forward with the strength of the arm knife.

At the moment when the giant ruin monster's arm knife was fully raised, it leaped forward and jumped into the hollow that was blown open by a grenade behind the giant ruin monster's eyeball.

Then he used the metal bone tip in his hand to violently destroy the circuit board and biochemical tissues in the hollow.

The giant ruin monster raised its cleaver high, and was about to slash under the ground when it slowly got up and didn't have time to escape, when suddenly its huge eyes froze, and its body froze in place.

The two small ruin monsters that were rushing forward frantically also seemed to be affected in some way at this time, and stopped together.

Then, the huge body of the giant ruin monster fell with a bang, and smashed right on the bodies of the two small ruin monsters, instantly flattening them into minced metal slag.

The ground shook, and a cloud of dust mushrooms rose.

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

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

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

Liu Hui, who was parked two kilometers away, heard the huge explosion here and the dust and smoke rushing into the sky, and quietly drove back.

happened to meet Li Teng who came from the dust.

And, of course, Gao Fei and Huang Xun.

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

In particular, a wound on the thigh, which was more than a dozen minutes long and two centimeters deep, turned upside down.

Although there are no medical cabins on the train, there are some anti-inflammatory drugs, bandages, and stitches.

However, the most serious injuries are not these three external injuries.

His head was violently concussed and impacted when the grenade exploded, and when the giant ruin monster fell, causing him to suffer from concussions.

Li Tengqiang asked Aisha to help him stitch up the three wounds one by one, and then lay on the bed and closed his eyes.

He didn't fall asleep, but fell unconscious.

Anna lay beside him and struggled to raise her head to look at Li Teng's injuries...... This guy is obviously running away and dying.

It's a pity she can't help anything.

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

In this plot, it seems that she either wins or loses, and she can only lie down anyway.

I have never acted in such a depressing scene.

……

Twelve hours later, Liu Yin's construction truck was upgraded from LV1 to LV2.

Although her body size has not changed much, her two robotic arms are noticeably thicker.

The reserves of the power supply are doubled.

Her tracked rollers have been upgraded to dual-purpose wheels.

On the outside of the track rollers, four huge independently driven off-road tires are suspended, ready to switch from track-type to tyre driving, which allows her to reach speeds of up to 80 km/h on some relatively smooth ground.

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

After the upgrade, the engineering vehicle leaves the train and starts cutting, and the work efficiency is obviously several times higher than before the upgrade.

The giant ruin monster has a high content of energy metal, and its hardness is also very high, and it is impossible to cut this hardness of energy metal at all after changing to the engineering vehicle before the upgrade. The upgraded chainsaw has the function of energy cutting, and the energy carried by the saw blade 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 a good combat effectiveness.

After encountering the small ruin monster from before, in a one-on-one situation, it will not be as helpless as before.

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

Liu Hui gulped down the energy metals.

The energy level of the train digestion system upgraded to LV2 has also been greatly improved, which 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 monsters, 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 for LV2 to rise to LV3.

Now Li Teng is in a coma, but everyone else thinks he is sleeping.

Daisy's injuries didn't worsen, so the team stayed with the corpse of the giant ruin monster for the time being.

Liu Hui wanted to wait until the upgrade was completed and the corpses of the giant ruin monsters and those small ruin monsters were all eaten before moving on.

……

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

At the time of LV2, the outer armor of the train was two centimeters thick, and the resistance to attack was equivalent to eight centimeters of steel plates.

After LV3, the quality of the outer armor alloy of the train has been greatly improved, although it is still only two centimeters thick, but the resistance to strikes is comparable to that of a 16-centimeter-thick steel plate.

The tire material of the train has also been fully upgraded, and when the train is stationary, the protective plate can also be lowered to fully cover the tires.

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

After the train was upgraded, Li Teng still didn't wake up, and Liu Hui couldn't ask Li Teng, but it was estimated that Li Teng would definitely give priority to upgrading the exoskeleton, so he decided to upgrade the exoskeleton again, preparing to upgrade the exoskeleton from LV2 to LV3.

Once upgraded, the exoskeleton will transform into a full set of armor that covers the entire body.

The alloy baffle on the chest, helmet and other vital parts will reach a thickness of one centimeter, and the ability to resist blows is equivalent to a steel plate eight centimeters thick.
