. South Vietnamese time, 8:12 p.m.

Six second-generation Dawners with black matte light stood on the side of the road one and a half kilometers away from the Halong Bay Naval Research Base. The black matte shade of night provides a nice protective color for the Dawners, as if they were non-existent.

"Let's get moving!" Shi Lei issued an order in the on-board communication system.

The maximum speed of the second generation of Twilight has reached 300 kilometers per hour, which is 83 meters per second! Such a high speed, under normal circumstances, can not be achieved, to achieve this kind of high speed, you need very good road conditions to be able to achieve.

Shi Lei drove the Dawner, walking in the front, and the on-board system of the Dawner fed back a lot of information to Shi Lei. Among them, the infrared thermal detector fed back to Shi Lei that there were two secret sentinels outside the naval research base.

"Three cannons, Mingxuan, you also found those two secret sentinels, right?" Although Shi Lei was asking, it was actually in an affirmative tone. "Snipe them!"

Zheng Sanpao and Zhu Mingxuan immediately set up a copycat electromagnetic cannon and aimed at the two secret sentinels through the sniper scope. The scope of the copycat electromagnetic gun is a little different from the scope of the sniper rifle, because the initial velocity of the projectile of the copycat electromagnetic gun is extremely high, the sniper scope of the copycat electromagnetic gun does not need to consider the wind speed and humidity.

The Dawner's exclusive electromagnetic cannon is more powerful than the third-generation copycat electromagnetic cannon carried by the second-generation Steel. After all, the Dawner's exclusive electromagnetic cannon uses a longer barrel, a stronger electromagnetic kit, a more ample power supply platform, and a better manufacturing solution, and it should be more powerful than the third-generation electromagnetic cannon.

The bullet mass of the Twellighter's exclusive electromagnetic cannon is still only 10 grams. However, due to the better power supply platform and stronger electromagnetic suite, it has an instantaneous charge of 1.08 million joules; An excellent manufacturing scheme with an energy conversion rate of 6 percent was adopted, so that the initial velocity of the projectile reached 3,600 meters per second, and the initial kinetic energy was close to 65,000 joules.

The two dark posts at the Halong Bay Naval Research Base are about 800 meters away, and this distance only takes 0.22 seconds for a projectile velocity of 3,600 meters per second.

Two pitch-black knock-off electromagnetic cannons emitted an air explosion sound of compressed air, two alloy projectiles with a mass of 10 grams, at a speed of 3,600 meters per second. Shot at two dark sentinels.

From firing a cannon to hitting a target, you don't even need a breath of time!

However, less than five seconds after the cannon was fired, the sirens at the naval research base went off. This is because the bullets of the two copycat electromagnetic guns are too powerful. Not only hit the target, but also penetrated the walls of the naval research base. A huge gap has been created.

Shi Lei smiled silently inside the cockpit. Quickly ordered: "Storm!" ”

Six pitch-black steel horns, divided into two groups. Zheng Sanpao and Ma Liang followed Shi Lei, and Zhu Mingxuan and Chen Xingrui followed Ye Feng. Two groups of personnel, one left and one right, slaughtered the naval research base.

Shi Lei and Ma Liang rushed to the front, and Zheng Sanpao held a sniper rifle and followed behind to provide long-range support.

Naval research base in Ha Long Bay. When the fence was overturned by electromagnetic cannons, he hesitated a little and then sounded the alarm. The searchlight on the wall actually found Shi Lei's group without dying.

Several high-power searchlights. The surroundings of the three pitch-black Dawners were illuminated as if it were day. The defenders of the watchtower on the wall shouted loudly in South Vietnamese.

"This is the Halong Bay Naval Research Base, the invaders surrender immediately, otherwise, they will be attacked!" The watchtower's shouters were not friendly.

Shi Lei sneered, although Shi Lei didn't understand South Vietnamese, Yi Shuer provided an instant translation.

"Three cannons, the watchtower is handed over to you, and our good son will kill it first!" Shi Lei commanded.

The Dawner driven by Shi Lei, the alloy sword and shield suit he chose, lacked effective long-range attack methods. He took Ma Liang, holding a shield in his left hand and a sword in his right hand, and rushed towards the gap that had just been broken by the electromagnetic cannon projectile.

The defenders on the watchtower found that Shi Lei and Ma Liang did not stop, but rushed into the interior of the research base, and they immediately launched an attack on Shi Lei and Ma Liang.

"DadaDada~"

The heavy machine gun emitted a hideous gunshot, and the 12.7mm caliber bullet was fired at Ma Liang and Shi Lei, but the powerful 12.7mm caliber bullet hit the special alloy shield, except for being bounced off, it did not cause any damage to the alloy shield.

The cockpit of the Twilighter, Shi Lei laughed, although the 12.7mm caliber bullet hindered the Dawner's progress, but it could not break through the Twilighter's defense at all.

"Bang~Bang~"

The watchtower attacking Shi Lei was hit by a projectile from the electromagnetic cannon, and the huge kinetic energy directly collapsed the watchtower. The huge kinetic energy made the masonry of the watchtower keep falling down.

Shi Lei and Ma Liang rushed into the research base, and inside the research base, although there were some defenders who used pistols and submachine guns to attack Shi Lei, the small-caliber, low-kinetic weapons did no harm to the Dawners at all.

The 260-kilogram alloy heavy sword is far more powerful than a thermal weapon in a small combat environment. The defense personnel inside the research base were beaten by Shi Lei and Ma Liang.

Shi Lei and Ma Liang rushed into the building of the research base, and the two of them used alloy heavy swords and alloy shields like street hooligans, slashing and smashing all kinds of research equipment and office supplies.

Shi Lei shouted while wielding the alloy heavy sword: "It's enjoyable! Very enjoyable! The news that Ling Yumo and Mu Shuang had been infected with a deadly virus made him feel very depressed. The current behavior is just a kind of venting.

Zhu Mingxuan, on the other side, also had a lot of fun. The big toy of the second generation of dawners is very much in line with Zhu Mingxuan's mind. I saw Zhu Mingxuan holding the exclusive copycat electromagnetic cannon of the Dawner, sniping at some high-rise buildings in the research base.

The Dawner's exclusive copycat electromagnetic cannon is very powerful, no matter what structure the building is, after being hit, it will be penetrated!

After nearly ten minutes of destruction in a row, Yi Shuer sent a prompt, "Sir, South Vietnam's Ha Long Bay Naval Base has sent reinforcements. There were two hundred marines in total, as well as a marine helicopter gunship. ”

Shi Lei was very surprised in his heart, the military strength of South Vietnam was very weak, and they were equipped with marine helicopter gunships, which really surprised Shi Lei.

"Three artillery, Ming Xuan, pay attention to one point, the Ha Long Bay Naval Base of the South Vietnamese State has sent reinforcements. There's a helicopter gunship coming, try to kill it outright! Shi Lei commanded.

The second-generation Dawner's airborne radar is quite advanced, and it is not difficult to detect the helicopter gunships sent by the naval base.

"Roger!" Zheng Sanpao replied steadily.

"No problem, boss, look at me!" Zhu Mingxuan looked a little immature.

"Ah Feng, Liangzi, and Xingrui, this time the reinforcements of the South Vietnamese State, in addition to a helicopter gunship, there is also a rescue team composed of two hundred marines. What should we do? Shi Lei asked a very easy question to answer.

Shi Lei has never been a soft-hearted person, as early as the test flight of the Steel, Shi Lei used the Steel Horn to destroy a 100-member border patrol group of South Vietnam.

Now that he has a powerful second-generation dawner, will Shi Lei still let go of the marines of South Vietnam?

"Kill!" Ye Feng's tone was solemn.

The other two followed Ye Feng and shouted the word 'kill' together!

"Let's go!" Shi Lei took Ye Feng and the three of them to meet them in the direction of the Halong Bay Naval Base.

The research base had been ravaged for nearly ten minutes, and all that was left was devastation at the moment. Not only were there a large number of casualties, but inside the research base, all kinds of research equipment and experimental data were frantically destroyed.

……

Halong Bay Naval Base.

When they received a call for help from the research base, they reacted immediately. The only marine helicopter gunship at the Halong Bay Naval Base was dispatched directly.

The Halong Bay Naval Base is 17 kilometers from the research base, and it only takes five minutes for a helicopter gunship to fly over. When the marine helicopter gunship was still two kilometers away from the research base, Zheng Sanpao and Zhu Mingxuan had already locked on it.

The radar of the second generation of the Dawner is very advanced, and as early as fifteen kilometers away, the on-board radar has locked on the marine helicopter gunship. It's just that Zheng Sanpao and Zhu Mingxuan have been waiting for the ocean gunship to get closer and enter the effective attack range.

"Master, do you make a move, or do I make a move?" Zhu Mingxuan has a very good sniper talent, he has apprenticed to Zheng Sanpao, and learned sniper skills from Zheng Sanpao, as well as explosion-related chemical techniques.

"Let's shoot! Be sure to kill it in one hit! Zheng Sanpao said cautiously, he was not sure whether the marine gunship carried the missile. In case the ocean gunships carry missiles, and they attack them with missiles, it's definitely a fucked up thing!

"Good!" Although Zhu Mingxuan has a playful heart, he also knows when to play and when to do things.

The two pitch-black knock-off electromagnetic cannons made a whistle of air exploding, and only half a second later, a fireball erupted in the night!

Shi Lei led Ye Feng and the three of them to run quickly on the wide highway. This road is the road leading from the research base to the naval base, and it is basically free of traffic in normal times.

The good road conditions made the movement speed of Shi Lei and the four of them reach more than 200 kilometers. They started working almost at the same time as Zheng Sanpao.

The combination of the Metal Heavy Sword and the Alloy Shield provides unrivalled melee power. Two hundred members of the Marine Corps, like two hundred sheep, were slaughtered by four male lions.

In less than five minutes, under the scanning of the Dawner's on-board infrared thermal detector, none of the two hundred members of the Marine Corps escaped!

The second generation of the Dawner, fully showing its fierce side....
