The ground shakes, from far to near.

The steel torrent of the tanks approached quickly, and the grass-green surface looked a little dull, but as it approached, an icy wave of killing aura hit like a tide, making people feel like falling into an ice cellar.

The team led by Lu Zhangyu is still very powerful, it only took half an hour to open the second layer of the arsenal, salmon quickly organized manpower, drove tanks to Nanquan City to support, the second layer of tanks, armored vehicles and artillery There are a lot of people, but there are not many people who can drive tank cannons, salmon searched all over the safety team and only found more than 50 people, and finally formed two squads, a team of ten tanks.

Snort –

The leading tank stopped, the chain rubbed against the ground, setting off a puff of smoke and dust, and the tanks behind were staggered in formation, lined up, uneven, obviously a little chaotic, but no one laughed, especially when they saw the black hole of the gun, there was a feeling of chill in the hands and feet.

Liu Wei'an and the Ping'an team were evacuated, no one died, only three were slightly injured, this kind of record, if at the beginning of the apocalypse, it is simply unimaginable.

"Fire—"

The salmon roared, and the sound was transmitted to all the tanks over the intercom.

Bang –

The ten tanks on the left shook, and a burst of fire erupted from the muzzle of the gun, and in an instant, they fell into the zombies across a kilometer of space, with a loud bang and flames.

Then there were ten tanks on the right, and ten flames drew ten traces in the void, some fell into the zombies, some shot into the building, and the sound of explosions filled the air.

Liu Wei'an and the others stood more than 100 meters away from the cohesive tank formation, still feeling the numbness of the ears from the impact of the sound waves, and the whole world was not clear.

"Fire—"

"Fire—"

"Fire—"

One by one, the shells were shot out, and the most dense places of zombies were blown up one by one, Liu Wei'an and others were all evolutionaries, they could be at a distance of one kilometer, and they could not obstruct their vision, and they could clearly see that the zombies were blown up with missing arms and legs, some flew into the sky, some were glued to the wall, and some of the upper body and lower body were separated, but they were not dead, and the upper body was still crawling on the ground, dragging out a jet-black wet mark.

"That's not how it was fought." The werewolf suddenly spoke.

"What?" Liu Wei'an looked at him.

"As a second-generation weapon tank developed, it is not used like this." The werewolf said in a deep voice.

"You know second-generation weapons?" Liu Wei'an stared at him, a little surprised.

"Can you let me command, I won't let any of these zombies live." The werewolf looked at Liu Wei'an with a very serious expression.

"Okay." Liu Wei'an stared at him for a long time, then turned on the walkie-talkie, "Pause the cannon, salmon come over." ”

The tank was turned off for about two minutes, the commander's order sounded again, why the commander was changed, the gunners did not know, they just had to listen to the face.

"Everyone obeys my command, and there must be no mistakes." The werewolf did not enter the tank, and when he took the walkie-talkie, he seemed to have changed as if he had become a general commanding thousands of troops, and there was a kind of instructive excitement in his eyes.

Liu Wei'an had a hunch that the tank formation would glow differently in the palm of the werewolf's hand.

"No. 1, No. 2, No. 3 fired first, three seconds later, No. 4 to 7, two seconds later, No. 8 to 12, one second later, No. 13-20, understand?"

"Understood!" The gunner responded, the pattern was odd, but it wasn't complicated.

"Okay, listen to my orders, No. 1, No. 2, No. 3, open fire!"

Phew-

The cannonballs rubbed against the air, making a piercing sound of breaking through the air. When the cannonball landed and exploded, and the firelight lit up the sky, the werewolf's serious voice sounded.

"No. 4-No. 7 fired."

When the shells fired by the second group of artillery hit the ground, the werewolf roared: "The third group fires!" ”

As soon as the third group erupted fire, the werewolf shouted: "The fourth group fires, immediately!" ”

Phew-

The fourth group of tanks has the most, a full eight, so the sound of breaking the air is also the loudest, the shells of the first three groups fall, and then explode, it is not unusual, it is no different from when Salmon commanded, the Ping An team and Salmon have some emotions in their eyes, and the werewolf does not see all this, staring at the last group of shells.

Boom –

The shell hit the ground and exploded, and something strange happened. The shells that had nothing to do with each other were suddenly connected in series, and the power of the eight shells superimposed and exploded together, producing the effect of sixteen or even twenty-four bombs exploding.

The flames were in the sky, smoke and dust were billowing out, and the explosion nearly tossed the ground in that area, and the vibrations passed under their feet, and the salmon and the peace team changed color in shock.

Especially the salmon, his eyes bulged, he couldn't believe everything he saw in front of him, the weapon was not a human being, how much ammunition was as powerful, this was calculated, only a little more, everything he saw in front of him subverted his cognition.

Everyone was shocked by this scene, only the werewolf had no expression, looking at his expression, he didn't seem to be satisfied with such an effect.

"What's going on?" Liu Wei'an asked.

"Everyone thinks that second-generation weapons are just powerful." Werewolves.

"Isn't it?" Salmon couldn't help but say.

"Yes!" The werewolf did not deny it, and immediately said: "But the real power of the second-generation weapon is definitely not powerful, because no matter how powerful it is, it is not as great as the nuclear magnetic cannon." ”

Salmon didn't know how to pick it up.

"The biggest secret of second-generation weapons is resonance." Werewolves.

"What do you mean?" Liu Wei'an asked.

"Everyone knows that sound waves and water waves have crests and troughs, but when the crests overlap, the power will expand infinitely." Werewolves.

"Second-generation weapons also have ripples?" The salmon stared at the werewolf, his eyes glowing, as if a new realm had opened.

"It's similar to a kind of ripple, but it's different, we call it frequency." Werewolves.

"What you just did was make the frequencies overlap?" Liu Wei'an reacted.

"That's right." The werewolf had some regrets, "I don't have detailed data on shells and tanks, so I can't make the frequencies superimpose perfectly." ”

"It's already amazing." Salmon admires it from the bottom of my heart.

"It's nothing." The werewolf shook his head, "The most powerful experiment I've ever seen, ten tanks, stacked on top of each other, produced the power of a nuclear warhead. ”

"That's an exaggeration." Salmon smacked its tongue.

"Otherwise, it wouldn't be called a second-generation weapon." A hint of nostalgia flashed in the werewolf's eyes, and he didn't know what he remembered.

"Can I learn from you?" Salmon Nie Nie said, blushing a little.

"Of course!" The werewolf smiled slightly, pressed the walkie-talkie and gave the order again, "Listen to my command, tanks 1 and 2 are in a group, and tanks 3, 4 and 5 are in a group......"
