The ejected acidic liquid covered the entire passage.
Good heavens, that single spray must have been accumulated over 18 years.
If this were on the ground, even if Zhao Feng could block the front, he'd still get hit.
But this is underground, so no matter how much it sprays, it can't get in~
With a few "sizzling" sounds, everything was evaporated by the energy field supporting it, leaving not a trace.
Instead, the acidic liquid that splashed into the passage melted all the normal zombies that were rushing over into carbon residue.
This was actually a fortunate accident that helped Zhao Feng.
He hadn't even figured out how to safely shut down the equipment after retreating to the safe house.
This solved the problem.
With the passage full of acidic liquid, no zombie could charge in for close-quarters combat.
Furthermore, the worm zombie needed some time to brew before each acidic spray.
He could completely use this opportunity to shut down the equipment and quickly retreat back inside the gate.
After successfully completing his task, the last problem he needed to face was...
Closing the gate.
Even though Zhao Feng had been desperately pulling at the gate after retreating into the safe house.
After 3-4 seconds, the gate had only closed by one-third.
Hearing Zhao Feng's low growl as he exerted himself, Li Ruolan slowly opened her eyes.
The fresh air that had replaced the stale atmosphere made her feel a little better.
Looking at Zhao Feng, who was steaming and growling as he struggled to close the gate.
She laboriously stood up and staggered over...
Zhao Feng, who was struggling to close the gate, was momentarily stunned when he saw a pair of delicate hands suddenly appear on the handle.
He quickly reacted, turning his head to look at Ruolan behind him.
Their eyes met, and everything was understood without words.
Their combined strength clearly sped up the gate closing process slightly.
However, the gate was extremely heavy, and the sliding track was jammed with the bone fragments of zombies, making every push even more difficult.
After another 5-6 seconds, the gate had barely closed halfway.
The worm zombie on the other side didn't care about Zhao Feng's efforts.
After brewing for a moment, it once again sprayed the acidic liquid from its abdomen.
Although he was struggling with the gate, Zhao Feng had been keeping an eye on the zombies' movements.
But seeing its large mouth slowly open, his mindset was somewhat about to explode...
There was no time for regret.
Seeing the acidic liquid spraying towards them, he turned and hugged Li Ruolan, pushing her to the ground.
The acidic liquid that then shot forward landed mostly on the gate, with the rest spraying into the safe house.
The wooden floor inside the room suffered greatly; the parts that were splashed with acid turned yellow and carbonized at a visible speed.
Fortunately, they had dodged in time and were not splashed by the acid.
Having narrowly escaped, the two quickly got up, intending to close the gate again.
But the gate, which had been movable moments ago, was now completely immobile, no matter how hard they pushed.
Sensing something was wrong, Zhao Feng quickly probed the guide groove on the ground.
He saw that the guide rail had become completely integrated with the iron gate.
Although this acidic liquid couldn't affect inorganic matter, the iron gate was still a type of metal, and the bio-acid sprayed on it had indeed caused a passivation effect.
The most severely eroded part was where the bottom guide rail connected to the iron gate.
Due to continuous contact and reaction with the acid, the passivation film had completely bonded the two together.
This directly jammed the gate, making it impossible to close.
Looking at the guide groove that was completely fused with the main gate, he understood that closing the main gate was now impossible.
At this moment, Zhao Feng once again felt the malice of this world.
On a hot day, his hands and feet turned cold, his body trembled with anger, and cold sweat poured uncontrollably.
'Is there no end to this? Lacking energy, being roasted by poison gas and high temperatures, and now a door-locking kill!? Star Sea Survival? I wish your grandmother a roll! Did I dig up your ancestral grave?'
The discomfort was real, but complaining wouldn't solve anything.
Calming down, Zhao Feng readjusted the output mode of the drilling laser.
Then, he suddenly flashed out from behind the door and unhesitatingly pulled the trigger.
The concentrated plasma flew through the 10-meter long passage and exploded into a fireball in front of the worm zombie.
The rapidly expanding flames heated the surrounding air, blasting the worm zombie away and twisting and tearing it apart in mid-air.
Looking at the entrance, which was instantly empty, Zhao Feng's eyes lit up.
He seemed to have grasped a blind spot he hadn't noticed before.
'I remember this weapon's attack range is 10 meters, right? Why does it explode beyond 10 meters? Why isn't the explosive power counted in the attack range?'
Actually, Zhao Feng's thoughts were not entirely correct.
The explosive-like effect was merely due to the narrowness of the tunnel, which restricted the energy release.
In an open environment, it would definitely not achieve such a powerful effect.
The terrain's limitation, combined with the fact that during previous uses, Zhao Feng had only seen its penetration and ignition effects due to the obstruction of many zombies, and had not seen the final stage explosion.
This is why he now found it outrageous.
'Damn it, is this toxic? What's with these panel stats? Is it a scam?'
Of course, he couldn't entirely blame the data panel.
The calculation of the drilling laser's attack range was based on the drilling operation manual as the standard.
During normal use, the drilling distance is only about 1-3 meters.
Coupled with the limitation of the equipment's energy level, there was rarely a need to drill beyond 10 meters.
Therefore, the data provided by the panel was actually quite reasonable.
Moreover, the power of the compressed plasma explosion, to be honest, was only effective against unarmored units.
It was fine for bullying normal zombies and worm zombies like the ones he was facing now.
After all, their condition was akin to being naked.
With their skinny hides, their armor rating was probably negative.
If it were a defensive type of mutant, it wouldn't have such a significant effect.
However, it wasn't too late to discover this move now. Although he was annoyed that the system panel's "unreliability" had put him in danger.
But now that he knew about this hidden attack method, how could he let it go?
He acted on his thought immediately, no longer shooting from behind the cover of the main gate.
Zhao Feng retreated to a position 8-9 meters away from the entrance.
He crouched down and aimed at the passage behind the gate.
Now that the indiscriminate attacks from the worm zombie had ceased, the number of normal zombies quickly gained the upper hand.
They were pouring into the tunnel incessantly, rushing towards the half-open gate.
Seeing the approaching zombie horde, Li Ruolan became a little anxious.
"Xiao Feng, shoot!"
Hearing this, Zhao Feng moved his lips.
"Don't rush."
By now, the zombie horde was less than 3 meters away from the entrance.
Seeing the zombie horde so close, Li Ruolan's face turned pale with fright.
She turned to look at Zhao Feng, and seeing that he hadn't fired yet, she thought there was a problem with the weapon.
At this moment, what filled Ruolan's heart the most was not fear of death, but a sudden thought of four words that were out of place with the current scene.
'I'm at a loss here!'
Just as she was considering whether to run to Zhao Feng's side, perhaps to die together, a crimson streamer flashed past her side and into the passage.
Immediately after, the compressed plasma was instantly released.
A burst of flames erupted.
The thick and solid steel wall contained the energy overflow.
The long and straight tunnel provided an unimpeded pathway.
The residual force of the inertial confinement field propelled the flames forward, causing them to surge out.
Following that, a violent explosion sounded.
