Unbearable

As they reached the end of the passage, the Astartes following behind to finish off the stragglers suddenly surged out in a wave, opening fire on the monsters still rushing toward them.

With more space, they could finally unleash their fists and feet.

Quilstein's eyes lit up when he saw the laboratory. He glanced at his brothers, all of whom were seriously engaged in battle, then stealthily made his way to an experimental table. He stared at the monster remains and the nearly viscous blue blood samples inside the container.

He nodded in satisfaction, then reached out and picked up the vacuum glass bottle encased in a steel frame beside it.

No one was around!

He immediately filled two large bottles with the blood, then hung them from his waist.

At that moment, a B-52 bomber had arrived above the base and dropped all its aerial bombs onto the mountain.

For a time, the entire mountain, along with the biological base beneath it, shook violently.

The deafening explosions even caused cracks to split open in some of the base's peripheral walls, sending dust and dirt tumbling out.

Tylert roughly surveyed the base's interior and precisely located the main power switch. He did not turn it on immediately. Activating the circuits during the bombardment could easily cause a short circuit.

However, he had already seen the layout and structure of the base clearly. He shook his head, somewhat dissatisfied. Still, with his experience and professional knowledge, resisting this wave of bombardment was more than manageable. The only problem was that the base's exit would probably be completely blocked by rubble from the bombing.

After clearing out the monsters in the base, the Blood Angels began searching through it alongside the Apothecaries and Tech-Sergeants.

Tylert had already begun repairing the short circuits in several areas once the bombardment ended.

After only a moment, a hum came from the power supply, and the pitch-black base instantly lit up brilliantly!

Tylert did not rest either. Once he had resolved the power issue, he began studying the base's structure and layout, thinking about a feasible way out.

He had already inspected the exit after the bombardment. It was indeed completely blocked.

Using his Chainsword, he cleared a passage large enough for an Astartes to move through. After clearing roughly two meters, he gave up.

Judging by the length of the exit passage when they had fought their way in, combined with the location where the rocks had collapsed after the bombardment, the blocked section was probably a hundred meters long.

If all the brothers worked together to dig, they could certainly get out. But the time it would take would also be enough for the mortal traitors outside to mobilize various armed forces and set up traps to wait for them.

Given the mortals' way of thinking, they might launch all kinds of missile attacks—or even use a nuclear bomb!

By then, not a single one of them would escape!

So he abandoned that plan outright. After searching and analyzing the facility, he eventually found an entrance and exit!

Moreover, its size was fairly suitable for an Astartes' physique!

But...

Once all the brothers stood at the entrance and took a look, they silently turned their gazes toward Tylert, who stood there lecturing them at length.

He had led them to the sewage disposal area!

Although the ground was still covered by various alloy plates and concrete, the passages and collection pools beneath them still existed!

After all, this was a facility for biological surgery experiments. The food, drink, and waste produced by the staff each day, along with the water required for the experiments and the biological waste generated during them, amounted to an astonishing quantity.

Thus, although the sewage pipes they had built were filled with all kinds of grates and agitators, they were extremely spacious. The wire mesh and other obstacles inside were nothing but child's play to the Astartes.

Tylert borrowed the plasma pistol from Quan Tiehua and fired several shots in succession, blasting open a hole in the floor large enough to accommodate an Astartes.

But the stench wafting from the hole could still be "smelled" by the Astartes despite their helmets!

"Brother! Is there really no other way?" At that moment, Dullens removed his helmet and walked over with a pilgrim-like expression. Imperial Creed and purity seals were carved and affixed all over his Power Armour as he looked toward Tylert.

"I don't want the Imperial Creed and purity seals on me to..." As he spoke, he somehow produced an Imperial Creed Codex as if by magic, held it reverently against his chest with both hands, and pleaded, "...or this Imperial Creed Codex to suffer such desecration! This is a masterpiece born beneath the Emperor's Golden Throne on Terra! There are only a few copies in the entire galaxy!"

Quan Tiehua watched the scene, unsure what to say. But to be honest, he did not want to go down there either.

Whoosh—

"Hey!" Dullens sounded somewhat angry as he held the Imperial Creed high to prevent it from suffering even the slightest contamination.

But the brother behind him had taken such a large step forward that some filth splashed up and nearly flew onto the Imperial Creed.

Dullens could not help but hiss angrily at him!

"Oh, sorry, Dullens! I didn't do it on purpose. I just didn't expect there to be bones here. You should have warned me—you were walking ahead of me!"

Lorenz did not want to argue with him, so he continued carefully forward, clutching the Imperial Creed Codex tightly in both hands.

Honestly, as an Astartes, he had never been this cautious since becoming one.

He slowly raised each foot, sweeping it left and right along the path the brothers ahead had already tested, checking for any danger of stepping into a gap or onto another bone.

The two leading the way were Quan Tiehua and Tylert. At that moment, Tylert's Power Armour was covered in filth from head to toe.

After everyone in the group had decided to take this passage, the crucial question had been who would go down first!

Tylert had come up with this terrible idea, yet he had even tried to wait until the very end before descending.

How could the others let him have his way? Several brothers shoved him straight into the sewage pipe, which was practically a septic tank, while he was off guard.

He landed in the water flat on his back, and his entire Power Armour was nearly submerged in the foul liquid.

As someone with a certain degree of cleanliness obsession, Tylert could not stand dirty Power Armour or such filthy behavior.

Thus, he looked somewhat withdrawn at that moment.

The ones suffering the most were the unconscious Chapter Master and Gers.

Although their injuries had stabilized and they had begun to recover, they still had not awakened.

As a result, two additional brothers had to carry them forward. But when they jumped down through the opening, the two of them were unbelievably unlucky.

First of all, wasn't the Chapter Master's shoulder guard being used by Quan Tiehua?

So when the foul liquid splashed up, it accidentally adhered to the gaps before flowing into the Power Armour!

On top of that, there was the burned flesh inside his Power Armour and the medicinal ointment smeared over it... Mm...

It was overwhelming!
