Transmigrated as a Ghost

After having cut off one of the colossal robot's legs the expedition squads' strike force rushed in to finish off their crippled enemy.

They seamlessly split into four groups of three and took different sides of the robot in order to split its focus. Now that it had lost a great deal of its mobility it would struggle to deal with attacks from multiple different directions.

In only a single instant each of the four groups had taken up their positions and launched themselves at the downed robot with their weapons ready.

They planned to continuous hack away at the colossal robot until it was inoperable, but it had already analyzed their strategy and developed a countermeasure.

On their approach it did not use any of its armaments to slow them down and let them get closer.

Then when it was about to be hit, the colossal robot launched a barrage of rockets and grenades around its body.

Previously it had refrained from using high yield explosive around its body to prevent causing damage to itself, but it had determined that the expedition squad's strike force presented more danger to itself than the damage it would sustain from using explosives in close quarters.

Several thunderous explosions rocked the area as the robot unleashed its payload and everything in sight was consumed by a giant ball of fire.

'Damn, I wasn't expecting a suicide attack.' Marcus thought as he jumped back and out from the explosion's radius.

He had been grouped up with Mrazivý and Miguel, and the three of them had escaped the main blast of the explosion.

Still, it had done no small amount of damage to the three of them, leaving several burns of Mrazivý and Miguel and having shattered Miguel's left arm that he had used to hold up his shield and absorb most of the impact.

Marcus himself could feel that his body had cracks all over it from the force of the explosion and saw some of his essence leaking out as a grey mist.

At the very least they had retreated far enough back that they were out of the robot's magic disruption field, and he was able to use his healing magic without any difficulties.

'Regenerate.'

To begin with he fixed Miguel's arm that was hanging limply. He next switched over to Mrazivý and by the time he had finished healing her his regeneration plus spirit healing had fixed his own injuries.

"I never expected it to self-destruct. I guess it wanted to try and take us all with it when it realized it was going to lose." Miguel said, his expression looking relieved.

"I'm not sure if that was enough to destroy it. We should keep on our guard until we see it turned into scape." Marcus said.

He had the sinking feeling that the colossal robot was not finished just yet. Certainly, the explosion around it had been terrifyingly powerful, but he did not think that it would destroy itself so easily.

"Let us go and check on the others and regroup. Thanks to Miguel's unique skill still protecting us I don't think anyone will have died, but we need to act quickly. We are on a time limit after all." Mrazivý said.

Nodding their heads, Marcus and Miguel agreed and the three of them rushed back towards where the colossal robot had been when it detonated thousands of explosives. 

When they arrived, they found that everyone from the strike force was still in one piece and had likewise gathered to check on the status of the colossal robot.

However, things were far from what any of them had expected.

The colossal robot had certainly suffered some damage from its own attack, but it was in far better condition than expected. Some of its outer armor had been warped and it had been blackened by soot, but it was mostly unharmed.

Still, worse than how little damage it had taken, the colossal robot was being repaired.

All over its body several smaller robots shaped like ants were going around fixing the damage it had sustained. Even its severed leg had been brought over and was in the process of being reattached.

This was shocking to everyone for multiple reasons, but the main one was that none of the other robots had shown any ability to restore themselves after being damaged. 

'Damn it. We should have foreseen this.' Marcus thought.

Their plan had been to cripple the colossal robot's mobility and whittle it down until it was completely destroyed, but that would have only worked on the assumption that it could not fix the damage it took. 

"We will have to hit it with everything we have all at once and hope it is enough. If not, I will at least make sure the three of us get out of here." Marcus said, a grim look on his face.

Miguel and Mrazivý looked equally dour but agreed. None of them wanted to abandon the others, but if they failed, they would be exhausted and the only thing that would pick them back up was Marcus' Supreme Skill which he only had four more uses of.

'I really did not want to use these since they use so many rare materials, but there is no choice.'

From out of his item box, Marcus pulled out an adamantine javelin and filled it with magic energy.

Once it had reached capacity, he tossed it towards the colossal robot with all his might.

Several guns moved to intercept the flying javelin and blasted it off course. The javelin continued to fly, though the hundreds of bullets hitting it knocked it off course.

It eventually impacted and sunk into the robot where it exploded.

Chucks of metal blew off the colossal robot and it now had a sizeable hole in its left side.

"I have three more javelins like that one! I'll use them to cover our approach! Everyone, get as close as possible and hit it with everything you have got! We need to bring it down quickly before it can repair itself!" Marcus shouted so that the entire strike force could hear him.
