Throughout the night, Sam was observing the opposition.
This group clearly had some discipline, taking turns at different times to watch their surroundings.
Their target seemed to be not only Sam, Different people, Were hiding in various concealed locations.
It had to be said, They were formidable!
Had it not been for a stroke of luck, Sam wouldn't have discovered them.
However, Now that he had found the enemy, he needed to think carefully about how to deal with them.
"I have an MP5SD submachine gun and a Type 54 pistol. The firepower is decent, and I could probably kill two of them wearing bulletproof vests in a surprise attack, but achieving the feat of killing seven or eight like before is impossible."
"Moreover, they might have firearms too, and since they have obtained law enforcement uniforms, it's very likely they have standard-issue weapons!"
"The technology of this era is much stronger than the one I came from! Even the firearms used by law enforcers are very advanced, much better than what I have!"
"There are many of them, and if they can't be dealt with all at once, what follows will inevitably be relentless retaliation!"
In the shelter, In the living room.
Sam was looking at a tablet, frowning deeply, pondering how to defend against the enemy.
The situation was complex for both sides, The advantages and disadvantages were clear.
If it were a normal person's shelter, facing this situation, they could only shrink back and not venture out.
But Sam felt that since the opposition had targeted him, they probably wouldn't give up easily!
Morning, Noon, Afternoon, Until night, Sam continued to observe, figuring out some of the opposition's behaviors and a part of their numbers.
He wasn't in a hurry, didn't leave the shelter, but sent out a second, third, and fourth drone, To observe the opposition from the concealed rooftops.
He, on the other hand, stood in the living room, using a projector to switch between screens, watching closely!
During this, Han Xiaowu saw Sam's serious expression and couldn't help but ask curiously, "What's wrong?"
"There are enemies outside."
Sam replied.
"Mobsters? Haven't you been seeing dead bodies outside these past few days? Those thugs have actually set their sights on us."
Han Xiaowu was also somewhat frightened, "Maybe we shouldn't go out then. Our shelter has plenty of supplies. Let's wait until they leave!"
"It's not that simple."
Sam shook his head.
A night passed, December 9th, The shelter tallied the points for the 8th, Due to the discovery of hidden enemies, the final tally was "51" points, which was considered a substantial gain.
Sam continued to observe and began to prepare for defense, spending points.
It was roughly concluded that some detailed information was obtained, revealing the number of enemies, A total of 15 people!
December 10th, The points for the 9th were tallied, A total of 22 points.
Sam continued to observe and unexpectedly discovered the leader of the opponents, a burly man.
To his surprise, among this group, there was also an old man, And his status was not low!
This elder was always busy in a room, going in and out in a hurry.
...
"Zheng Hao!"
In a bungalow, two robust men wearing thick radiation suits walked in and called out, "Elder Master Zheng says the thing is ready!"
"Hmm?"
Zheng Hao's gaze shifted, he said in a deep voice, "Go take a look!"
"Yes!"
Several people filed out and arrived at Elder Master Zheng's room.
It turned out to be a crude chemical laboratory, with all kinds of strange materials!
Elder Master Zheng, wearing a radiation suit, said in a deep voice, "A total of five bottles of water, the stuff you've scrounged up these days, is only enough to make these."
"That should be enough!"
Zheng Hao's eyes brightened, he said fiercely, "Get the brothers ready, we'll break through their gate tonight!"
"Okay!"
"Okay!"
The robust men nodded, beginning to go back to conserve their energy.
They had waited too long, For a quality shelter, lurking here for ten days without changing clothes.
Then, The group dispersed, Zheng Hao also left the lab to prepare weapons.
Unaware to them, far away on the rooftop of a flat building, a drone with a camera hanging beneath it was closely monitoring this side. People, firearms, strange bottles, and that laboratory...
"Here they come!"
Inside the shelter, Sam let out a breath, his eyes flashing with a glint.
"What should we do?"
Han Xiaowu, somewhat panicked, suggested, "Should I go reinforce the shelter's main door?"
"That's a solid steel door; not even a rocket launcher could blast it open!" Sam shook his head.
The construction of the shelter was strictly demanded by him, like the double-layered doors, each made of thick solid steel, impenetrable by bullets, and likely resistant to even artillery shells.
But since the enemy had mobilized, they would surely use some special methods!
"Those tools, they seem to be from a physics and chemistry lab..."
"What method will they use, I wonder?"
Both sides have their schemes, one side is poised and ready to strike at night, while the other side is cheating by preparing defenses against the attack.
Zheng Hao and his group think they are well-hidden and can surprise Sam, but little do they know, everything is under Sam's surveillance!
In fact, over the past few days, Sam has been considering creating a military drone, one of those larger models equipped with lethal weapons capable of easily taking out thugs.
However, he doesn't have enough points, and considering the complex urban road conditions and the abundance of buildings, the effectiveness of the drone would be significantly reduced, so he's been forced to think of other methods.
Time quietly flies by. Unnoticed, it becomes night!
A cold wave arrives, leaving the world in utter silence.
In the darkness, fourteen fully armed strongmen and the elderly Zheng Lao, tread softly towards Sam's shelter.
Darkness, cold silence, and a chilling murderous intent.
Finally, the group arrives at the entrance of the shelter. Zheng Hao touches the steel door, a look of admiration flashing in his eyes. It's the best door he has seen for a personal shelter, almost perfectly secure.
Unfortunately, a steel door is still made of steel!
"Bring the stuff!" Zheng Hao whispers.
According to their observation, the people in the shelter should be resting at this time.
"Okay!" Behind him, Zheng Lao brings forward the materials, including a few bottles of "aqua regia" and two "thermite" agents.
With a cold expression, Zheng Hao sprays the aqua regia on the steel door.
Visibly, the steel corrodes, becoming pitted and uneven, with small holes dissolving open, making the appearance much more tragic in an instant.
One bottle, two bottles, three bottles...
After three bottles of aqua regia were applied, the thick steel door was not yet breached but had already become battered and torn, still thick and heavy, making it impossible to break through with brute force and firearms.
Zheng Hao handed the remaining two bottles of aqua regia back to his subordinates and took out the thermite, spraying it on the door!
With a whoosh, the thermite, a type of spray, was applied all over the door. White smoke rose in the darkness, and a remarkable heat surged over the steel door, even dispersing the surrounding cold.
The next moment, a chemical reaction more terrifying than that of the aqua regia occurred, and the steel door visibly disintegrated at a rapid pace, becoming extremely thin.
Moments later, Zheng Hao's expression hardened, and he fiercely kicked the ruined door!
Bang—! The door shattered, falling to the ground.
"It's open!"
"Ha ha, impressive!"
"Intellectuals are truly powerful!"
The men whispered among themselves, all very pleased, and Zheng Hao was satisfied.
Only Elder Zheng frowned deeply.
"Something's odd!" he couldn't help but whisper. "I had estimated the door's strength, which is why I judged that five bottles of aqua regia would be enough to break it, and the two thermite charges were supposed to be used in conjunction. How come now only about half was needed?"
"That just shows how strong your stuff is!" Zheng Hao laughed.
In his mind, Sam was still asleep, and by the time they stormed into the shelter, the other party might not even have time to react.
"Perhaps," the elder was not sure and did not dwell on it further.
The group moved inside, quietly making their way down the corridor, step by step, very slowly.
Along the way, Elder Zheng furrowed his brows tightly, taking several deep breaths, sensing something was off with the smell.
However, the corridor was short, and before he could ponder further, they encountered another steel door!
"How is there another door?"
Everyone was shocked, and Zheng Hao, with a slight shift in his gaze, said, "A very professional shelter, luckily we still have some aqua regia and thermite."
As he was about to proceed, at that moment, Elder Zheng's nose twitched, and he suddenly thought of something!
He looked around, on the ground and walls of the corridor, there were streams of liquid with a pungent smell!
Because it was too dark at night, and since they had just used aqua regia and thermite, they hadn't noticed these pungent-smelling liquids.
But Elder Zheng, knowing what he was dealing with, immediately realized what those substances were!
"Gasoline!" he exclaimed.
Zheng Hao frowned and turned to ask, "What gasoline?"
"Run! We've been tricked!" Elder Zheng's face was stricken with terror, and he turned to run back without hesitation.
Everyone was stunned, but Zheng Hao, making a quick decision, shouted for a retreat, leading everyone to run back outside.
But just then!
Bang—! Above the door they had corroded, a mechanism opened, and a brand-new steel door fell, sealing their retreat!
"Double doors!" Elder Zheng's face went pale, and he said with a grim laugh, "I get it now, no wonder something felt off. The door is double-layered! One layer didn't come down!"
"Break it!" Zheng Hao roared, his eyes bloodshot.
At that moment, from a speaker on the corridor wall, came Sam's voice.
"Not returning a favor is against the rules!"
"Welcome, gentlemen..."
"To my shelter!"
