Seeing his adoptive father's hard-working posture, Chu Yifei had the urge to laugh, and hurriedly lowered his head and looked at his feet to avoid the old man seeing his grinning lips.
Fortunately, Carpenter Xie was focused on the mountain road, so he didn't notice Chu Yifei's snickering, otherwise he would have given Chu Yi a flying kick and kicked him in the butt!
Just as the two people were chatting and waiting, a dull explosion suddenly came from a mountain behind them, followed by a small mushroom cloud of smoke rising into the sky with great momentum.
To be scary.
But Xie Carpenter and Chu Yifei just turned their heads and glanced, and then turned back calmly, with a familiar expression!
They knew that this must be the great engineer Mo Yanran who was experimenting with new weapons. This kind of explosion would go off almost ten to eight times a day. At first they were frightened when they heard it, but as time went by, people got used to it.
, no longer panic.
At this time, a car whistle came from the mountain road, and it reached Carpenter Xie’s ears from afar!
Although the sound was still relatively weak, Xie Carpenter still heard it, and he shouted in surprise, "Here we come, the motorcade is back!"
Chu Yifei interjected at the side, "Godfather, you are already in your fifties and sixties, can you be more steady?"
Xie Carpenter glared at him angrily, "Get out of here, old man, I'm so happy, get out of here!"
Chu Yifei rolled his eyes after saying this. He had no choice but to move a few steps to the side, otherwise he might be hit by a flying kick!
Luo Xiao and his team's convoy moved forward very quickly. The mountain road was relatively wide and flat, and some places had been widened and corrected by them, so it was very smooth to walk on.
When the long convoy appeared on the mountain road, Xie Carpenter looked at the high-rise goods on the car and grinned happily, "Hey, it looks like there is another bumper harvest, good, good, good!"
The motorcade approached the first checkpoint, then slowed down slowly, and finally stopped in front of the first checkpoint.
Luo Xiao opened the door, jumped out of the truck, then looked up, and couldn't help being surprised!
He did not expect that in the more than a month since he left, the Huxiaoling base would have changed drastically. Even the original three checkpoints were different from before.
The original checkpoint was just a stone wall with a wooden gate on it. Two simple observation towers were built on the hillsides on both sides of the stone wall. The entire checkpoint was very simple.
As for the current first checkpoint, the original thin stone wall has been demolished and replaced by a stone platform seven to eight feet high and three to four feet thick, blocking the entire mountain road.
The outer layer of the stone platform is entirely made of one-meter-square bluestone, and is divided into two layers, the inner and outer layers. The middle layer is filled with tamped soil, while the inner layer is made of concrete.
On the outside of the stone platform, a passage was built in the middle of the stone platform, which is three feet high and two feet wide. A solid iron gate is installed. If you want to pass through, you can only go through this iron gate.
On the stone platforms on both sides of the iron gate, a group of five bunkers were built in a row. Each bunker had eight perforations, allowing light and heavy weapons to fire at the same time. The entire mountain road was completely covered by crossfire.
, there is no blind spot at all. Even in the passage behind the iron gate, the walls on both sides are covered with perforations. Enemies who enter the passage will be greeted by a storm of bullets.
On the top of the stone platform, there are four lookout bunkers, each equipped with four high-precision infrared military cameras, connected by lines to the control room in the stone platform, where people are on duty 24 hours a day.
In addition, two miniature radars were installed in the lookout bunker, which provided round-the-clock, all-round, 24-hour monitoring. No matter whether the devils came from the ground or from the sky, they could not escape.
Take off these vigilant "eyes".
Luo Xiao looked at the checkpoint, which was almost built into an invincible fortress, and was a little speechless: Such rigorous equipment can almost catch up with the base facilities of that era. It seems that Yan Beifeng's interest has not changed!
"Luo Xiao, do you think this facility is good? It's okay." Sure enough, as soon as he thought of this, Yan Beifeng spoke from the side, "It's a pity that the power plant has not been built yet, otherwise I would have removed the facilities in the warehouse."
Several wire-controlled automatic machine guns have been installed to ensure that when the Japanese come, they will be surrounded by a honeycomb!"
"Automatic machine gun?!"
Luo Xiao could only smile bitterly. He had already expected that Yan Beifeng would not let go of that powerful weapon!
The automatic machine gun is automatically controlled by a built-in computer chip and has a very sensitive sensor. Any enemy target within 150 meters will be attacked by it. The best way to get rid of it is to destroy it.
The wire-controlled automatic machine gun is one of the newly developed weapons in the arsenal. It is divided into two types: manual wire-controlled and chip automatic control. The main models are divided into three types: Jianyu 1, Jianyu 2, and Jianyu 3.
, the one with the lowest rate of fire has reached 1,500 rounds per minute, which is more than double the rate of fire of the Maxim heavy machine gun. It can be described as a storm!
In the ammunition depot inside the stone platform, tens of thousands of automatic machine gun bullets are stored in advance, and they are connected through a special transmission device, allowing for uninterrupted shooting, which is very terrifying!
It can be imagined that when this kind of bullet rain instantly covers 150 meters in front of the stone platform, it will definitely be a nightmare for the enemy.
Luo Xiao knew without even thinking that this perverted thing must have been invented by the weapons-making genius Mo Yanran!
Although the Metal Storm invented by the Australians could theoretically reach tens of thousands of bullets per second, in fact it later proved to have huge flaws and was eventually eliminated!
The Arrow Rain type automatic machine gun invented by Mo Yanran is already one of the most advanced automatic machine guns in the world!
Although he was helpless at Yan Beifeng's evil intentions, Luo Xiao still didn't say anything, but directed the soldiers to drive the truck into the first checkpoint.
Behind the first checkpoint, there were two more checkpoints. When Luo Xiao saw that each checkpoint was similar to the first checkpoint, and even the third checkpoint was equipped with several surface-to-air micro-missiles, he was completely speechless.
Got it!
With such a tightly protected Huxiaoling base, let alone the Japanese in this era, even if it develops fifty years later, they may not be able to defeat it!
But this is good, at least it relieves Luo Xiao's worries and allows him to do it freely!
The motorcade moved forward, passed three checkpoints, and arrived at a hidden parking lot located inside the third checkpoint.
Before the car was stable, Xie Carpenter came running over with Chu Yifei.
