Chapter 905: Preparations Before Returning

The battle lasted for over half an hour before it finally came to a stop.

Sun Cheng looked down at the dozen or so extra wounds on his chassis, and suddenly understood why those ancient Cybertronian warriors had failed to eliminate all the Shadow Guards back then.

"Forget it, let's withdraw for now. Once a batch of electromagnetic weapons is prepared here, we'll come back and wipe them out completely!"

On the ground all around, more than twenty Shadow Guards were either severed at the waist, severely damaged, or paralyzed by electromagnetic weapons.

Even though Sun Cheng now possessed strength nearly at the Leader Class, he had still been injured while facing these cold, fearless combat robots.

Should one say that they were truly worthy of being killing machines created by a Cybertronian elder!

Although Sun Cheng had once had the same idea, and even currently possessed a considerable number of combat robots under his command.

But the robots he manufactured could only be used to consume the cannon fodder warriors cultivated by Starscream, belonging to a lower existence than cannon fodder.

Conversely, these Shadow Guards created by Maximus had strength that, at the very least, was comparable to an Advanced Decepticon Warrior.

Although the patrol squad leader level was still an Advanced Warrior, relying on their cold, fearless nature, I am afraid that even Elite Warriors would not be able to take them down in a short time, and it is estimated that even if they were resolved in the end, they would not escape being injured.

With a wave of his hand, he stored the remains of the Shadow Guards he had eliminated into his Spherical Space.

These Shadow Guards could maintain long-term patrols here in the Underground Ice Lake at nearly minus one hundred degrees, so it was clear that their chassis materials had undergone anti-low-temperature treatment.

Even Sun Cheng himself could barely handle it, having to constantly consume the energy in his Spark to generate heat to keep his chassis surface from freezing.

This shows the technological content of this technology.

Taking it back for the Decepticon Engineers under his command to study, if they could research and master it, it would be more convenient to operate in extreme environments in the future.

Sun Cheng glanced at the other side of the ice wall that had condensed on the lake; he had a feeling that there were more Shadow Guards over there, and in no small numbers.

He even suspected that the reason those Cybertronian warriors from the ancient era chose to withdraw without completing their mission.

The root cause was that on the other side of the ice wall, there was very likely a hidden automated manufacturing factory capable of continuously producing Shadow Guards.

The Cybertronian warriors from the ancient past should have been the same as him now, with chassis unable to fight for long periods in extremely frigid environments.

If the result was truly as Sun Cheng himself guessed, even he could only choose to retreat for the time being.

Even powerful leaders with a hundred battles under their belts like Megatron and Optimus Prime would be severely injured or even worn down to death if they faced hundreds or thousands of Advanced Warriors head-on.

"What a pity, I can only withdraw for now!"

Although Sun Cheng felt regret in his heart, he felt no unwillingness.

Since this Laboratory had already been discovered by them, it was right here and could not run away; sooner or later, everything inside would be theirs.

Thinking of this, he turned and walked to the edge of the ice lake without hesitation.

Before going ashore, Sun Cheng turned around and looked down once more, locking eyes with the mechanical giant beneath the ice lake that had been frozen for who knows how many years.

He then turned and walked onto the shore, quickly arriving at the cave entrance, pulling out his Heavy Sword to cut down the ice blocks in the passage like cutting tofu, transporting them to the entrance leading to the ice lake to reseal the Underground Ice Lake space.

During the battle with the Shadow Guards, Sun Cheng noticed that they had never approached the edge of the lake.

Combined with the fact that this Laboratory had existed for who knows how many years, yet the Shadow Guards had never appeared in other regions of Mars, it seemed they must have been given orders not to leave their patrol area without authorization when they were created.

And their patrol area should be in the vicinity of the Underground Ice Lake.

As for the purpose, it was undoubtedly to guard the mechanical giant in the lake whose life or death and status were unknown.

Sun Cheng quickly returned to the surface, where more and more Decepticons had arrived and begun to get busy.

As soon as Sun Cheng walked out of the passage leading to the Underground Ice Lake, he was immediately noticed by the Decepticons present.

An Advanced Warrior who had taken over command duties after he left also noticed his return at the first opportunity.

When seeing the dense, tiny wounds on Sun Cheng's body, they also hurriedly approached and asked cautiously: "Commander, is it very dangerous down there?"

"Yes! For you!"

Sun Cheng glanced at an Advanced Decepticon Warrior who had just arrived not far away and said: "Thor, have the Base send over a batch of Liquid Nitrogen to temporarily seal this cave entrance; it is strictly forbidden to enter without my orders!"

"Yes, Commander!"

With a wave of his hand, he took several relatively intact Shadow Guard corpses from the Spherical Space and placed them in front of Thor.

"These are Shadow Guards, a type of combat robot created by the ancient Cybertronian civilization. Each one possesses at least the strength of an Advanced Warrior, and they are fearless. Send people to take these back to the Base first and have them study them carefully!"

The nearby Decepticons all curiously crowded around to look, as did that Advanced Warrior.

Being able to leave wounds on Sun Cheng's body already proved the extraordinary nature of these so-called Shadow Guards.

What made them feel even more amazed was that these combat robots could actually survive for a long time in the harsh, ultra-low-temperature environment, and had existed for so many years.

Two scanning beams shot from Thor's eyes, carefully examining one of the Shadow Guard corpses for a while, and the expression on his face had already turned from surprise to delight.

"The chassis material of this combat robot is very special; it is a special alloy we have never seen before, and it seems to have been created specifically to resist the bitter cold... Commander, give us some time; even if we cannot fully replicate this special alloy, the performance should not be too far off!"

Sun Cheng found these words very satisfying; as long as the batches of Decepticon Engineers under his command continued to research one after another, one day, he might be able to climb the technology tree back to the peak of the former Cybertronian civilization, or even higher.

However...

The premise was that they could not perish before then!

Nodding slightly, Sun Cheng stopped worrying about how they would handle the corpses of these Shadow Guards.

He would stay in this Laboratory for a few days to hold the fort until the Mars Base mobilized enough manpower and resources to re-excavate this Laboratory of Maximus and put it back into use.

Taking advantage of this time, Sun Cheng and some Decepticons at the Mars Base formulated a set of defensive fortifications set up around Mars.

Seeing that the main force of the Decepticon Legion led by Shockwave was about to arrive, and even the plunder fleet of the Quintessons had once been active in the star sector nearby.

If he did not make preparations in advance, Sun Cheng would not be at ease.
