In fact, Ye Lei didn't have time to think, because the soldiers were already only three meters away from them!

At this moment, Xiuxiu, who had been standing quietly at the back, suddenly took a step forward, faced the soldier in front of her, and unleashed her unique superpower—the Lion's Roar.

"Roar..." In this cramped space, a powerful gust of air almost blew off the soldiers' helmets. The deafening roar was like thunder, making the four people present dizzy and in unbearable pain. They all subconsciously covered their heads.

Even Ye Lei and Tang Xiaoting, standing behind Xiuxiu, were affected by the loud roar and couldn't help but frown. However, only Xiuxiu, looking at the disheveled state of the soldiers in front of her, showed a relieved smile.

This earth-shattering roar echoed for a full thirty seconds in the sealed air-raid shelter. Undoubtedly, this awe-inspiring roar reached every corner, and everyone clearly heard this terrifying sound.

Compared to the zombies, the soldiers were clearly much stronger. Within a minute, the soldiers quickly regained their senses, which undoubtedly proved that Xiuxiu's Lion's Roar technique had flaws, with too short an awakening time and insufficient power.

Realizing the situation had changed, the soldier pulled the trigger without hesitation, and the flame-spitting bullets whistled toward them.

Only then did Ye Lei realize that something was terribly wrong. He was preparing to activate his special ability—space stillness—to stop the bullets hurtling towards them.

At this critical moment, a transparent oval sphere emitting a faint white light suddenly appeared and tightly enveloped them.

All the bullets fired at this sphere fell to the ground as if they had lost their power, like an indestructible wall of bronze and iron.

"What exactly is going on?"

Ye Lei was astonished. His eyes searched around, and finally, his gaze settled on Tang Xiaoting, whose eyes were tightly closed. He thought to himself, "There's no one else here. Could this mysterious protective shield be the work of Tang Xiaoting? Perhaps it's because she's pregnant that she awakened such a powerful ability?"

Faced with this unbelievable scene, the four soldiers opposite were equally stunned.

Their eyes widened in disbelief as they watched what was happening before them. Just as the warhead hit the ground, Ye Lei knew he couldn't wait any longer and activated his Hellfire ability.

Instantly, a burst of lightning struck the antennas on the soldiers' helmets, which became excellent conductors of electricity. Just as the bullets and casings hit the ground, the four soldiers were also struck by lightning and fell to the ground, while the protective shields surrounding them disappeared.

Without hesitation, Ye Lei drew his lightsaber, its blade gleaming with a dazzling blue light.

He strode forward with firm, powerful steps, as if walking on flat ground, and easily killed the four soldiers.

Looking at those four terrified faces, it was clear that these people did not understand what had happened until their deaths.

This was not the time to question Tang Xiaoting. Ye Lei controlled Tu Xingsun to drag the four corpses to the next room and quickly cleaned up the traces on the ground.

Time was of the essence; they had to escape before the main force arrived.

When they reached the corner at the end of the corridor, they saw a group of people in white coats rushing back in the direction they had come from.

It is highly likely that these people were startled by the earth-shattering "Lion's Roar" and are now fleeing at breakneck speed.

Could that be the exit? However, the area on the other side has not been fully explored yet, and the military's awakened superhumans are likely in that corridor on the other side.

This put Ye Lei in a dilemma, making it difficult for him to decide which direction to take.

Adhering to the principle that opportunity knocks but once, Ye Lei thought to himself: Now that I've come all this way, I might as well go all out and find out the truth.

Perhaps those large troops are lying in ambush at the exit, waiting for them to walk right into their trap! Thinking of this, Ye Lei resolutely strode towards the other side, a sight that terrified Tang Xiaoting. She couldn't help but wonder if Ye Lei had gone mad or lost his mind.

"Brother Lei, shouldn't we escape from here immediately?"

Tang Xiaoting anxiously offered a reminder.

"The investigation is not over yet; we cannot give up halfway!"

Ye Lei glanced at her and replied firmly.

"However, what should we do if the main force arrives in a while?"

Tang Xiaoting looked worried.

"It's alright, let's keep going and catch them off guard. Perhaps they're currently lurking at the exit, waiting for us to come out so we can ambush them!"

Ye Lei analyzed.

"That's quite possible. This area is so vast, they probably don't know our exact location. Adopting a wait-and-see strategy is indeed the best approach."

Tang Xiaoting was once again deeply impressed by Ye Lei's wisdom.

"That's true, but it's just my speculation. Let's treat it as a gamble and set off!"

Ye Lei spoke as he took steps.

Time was running out, so Ye Lei pulled Xiu Xiu along, with Tang Xiaoting following behind, and strode towards the next corridor!

Upon entering the first room, they found it to be a "control room." What was it used for? Ye Lei gently pushed open the door. Inside sat a man in a white coat with his back to them, wearing headphones and seemingly engrossed in music.

No wonder the Lion's Roar I unleashed at such close range had no effect on him whatsoever!

Ye Lei stared intently, full of doubt, at the indicator lights flashing in various colors above the control panel, his eyes revealing increasing interest.

He tiptoed into the room and crept towards the person in the white coat.

When he got behind him, Ye Lei raised his hand without hesitation and slapped the back of the white-coated man's neck with all his might.

With a muffled thud, the man in the white coat tilted his head to the side and slumped limply against the chair back like a deflated balloon.

The control panel was covered with all sorts of buttons and switches, and also shone with dazzling colored lights.

Faced with this complex and unfamiliar set of equipment, Ye Lei was completely bewildered. Suddenly, he noticed two rows of lights that caught his attention. It turned out that each light bulb was clearly labeled with a number from No.1 to No.10.

However, these numbers seem to have no practical meaning. The only thing worth noting is that, except for bulbs No.1, No.2, and No.4 which are off, the other seven bulbs are emitting a bright light.

At this point, Ye Lei suddenly realized: it turned out that he had already killed the two superhumans, No.1 and No.4. But why was No.2's light also out? That was unknown. However, this also meant that at least seven survivors who had awakened their superhuman abilities were still alive and well.

So the question is, where are these seven people now?
