With an environmental simulation device on the surface of the robot, the puffer fish gladiator silently melts into the darkness. With Qin Yujie controlling the mobile control system, the strangely shaped and strangely equipped robot swayed forward on its legs, but it was only a few minutes before it approached the towering city wall crawling in the darkness.

"There are still defenders on the city walls, and it is impossible to sneak in quietly." Sister Qin frowned.

Lin Xiao sat in the weapon control cabin and said with a smile:

"Ah, our goal is to blow up the walls, not to walk up the ladder."

As he spoke, there was a mess on the weapon console, and two silver-white metal tentacles suddenly stretched out on both sides of the puffer fish gladiator's body: "This is a super-bionic robotic arm that simulates the ability of Doctor Octopus in Spider-Man, using special elastic fiber weaving, the adsorption power is amazing, enough for us to make a cameo appearance in Spider-Man." ”

The problem was solved, Sister Qin didn't talk nonsense, and controlled the puffer fish gladiator to slowly approach the city wall, and the two silver-white tentacles quietly attracted to the city wall, like a big gecko in the night, climbing up.

This is a city wall that has been standing majestically for a hundred years, the wall is mottled, covered with traces left by wind and rain, and has the taste of the vicissitudes of time. The walls of the city are 50 meters high, and near the south gate, a special type of armored giant has been broken, and a gap of eight meters in diameter and fifteen meters in height has appeared.

In the original play, the Taurus Special District almost fell, and finally relied on Alan to transform into a giant and carry a boulder to finally plug the gap.

It is precisely because of this gap that the originally impregnable city wall has a flaw. It also made Lin Xiao and others' ambition to destroy the city wall successful.

"The first point" Sister Qin said in a low voice: "It's here, you can put the bomb." ”

Lin Xiao nodded, took out a gray metal device from the storage space, and slapped it firmly on the crack of the gap.

"C4 explosives pack. Origin "Crossfire". Price: 800 points. ”

"C4 plastic explosives, abbreviated as C4. Its main component is polyisobutylene, made of gunpowder mixed with plastic, which is extremely powerful, and the name C4 comes from the fact that there are 4 carbons in each monomolecular structure. It is a highly effective explosive made from a mixture of high-performance explosive substances such as TNT, semtex and white phosphorus..."

"Juggernaut Evaluation: Small, Practical Explosives, Weapon of Choice for Suicide Attackers!"

Lin Xiao pursed his lips, "It's a sharp complaint."

Although the process is tedious and tiring, there is no danger. Ten minutes later, Lin Xiao and Qin Yujie had successfully placed the C4 explosive pack at four points. During this time, Hitman 47 also put the Valkyrie bomber that caused the commotion into the storage space. The two men clinging to the walls of the city and doing a campaign of destruction were not spotted by the Defenders or the Adventurers/Giants.

Boom, boom, heavy footsteps rumbled from far and near, Lin Xiao, who was placing the most rearly explosive pack, raised his head in surprise, and saw that in the skyrocketing fire and smoke, a giant with a height of fifteen meters was carrying a huge stone and trembling slightly from a distance.

"It's going to return to the plot, yes." Lin Xiao shrugged, shook his head and said, "It's a pity, you're too late."

As she spoke, she slapped the last pack of C4 explosives in her hand into the rock crevice, and Sister Qin, who had already explored the mobile control system of this rudimentary robot, jumped down without the slightest hesitation. Boom after tens of seconds!

The five C4 explosives that had been calculated to the key points exploded in unison, and the air waves and flames produced did not have a terrifying sound, but the consequences of the explosion were devastating impacts - the city wall, which had stood for a hundred years without falling, collapsed in a crumbling and crumbling after a painful wail, splashing the sky with dust!

"Retire after a successful job."

Lin Xiao stood in the distance, squinted his eyes, and said softly: "This is the domino effect."

The "domino effect", the energy generated by this effect is enormous. The physical principle of this effect is: when the domino is vertical, the center of gravity is higher, the center of gravity drops when it falls, and in the process of falling, its gravitational potential energy is converted into kinetic energy, and it falls on the second card, and this kinetic energy is transferred to the second card, and the second card transfers the kinetic energy from the first card and the kinetic energy converted from the gravitational potential energy that it has in the process of falling, and then passes it to the third card, so when each card falls, it has a greater kinetic energy than the previous card, so their speed is faster than the other, that is, The energy that they push down in turn is greater than the other.

As a result, five inconspicuous C4 explosive packs destroyed a huge city wall that was 50 meters high and 7 or 8 meters thick. A thousand-mile embankment was destroyed in an anthill, and nothing more.

The walls fell, and the earth trembled with a roar. The cold and merciless chime of the master sounded in everyone's ears:

"You completed the first part of the hidden mission, and you earned 1,000 points."

Except for the adventurers, all the aborigines were stunned. The Wehrmacht, Allen, who has become a giant, they don't understand what has just happened. But the tidal wave of giants that surged from the collapse of the walls sowed despair in the hearts of all—destruction was coming!

The city wall, which had collapsed dozens of meters, could not be stopped no matter what. The influx of giants not only represents the fall of the Toroste region, but also has a cruel and bloody implication - the civilians in the city who have not had time to retreat will all die!

That's more than hundreds of thousands of ordinary people, how can they escape the slaughter of giants when they are unarmed?

The heaviness was suppressed in everyone's hearts, and everyone tacitly avoided this topic. Sometimes, people are really helpless to live.

The killer said silently: "Let's go, it won't be long before this place will fall, and we must quickly enter the third layer of defense." Otherwise, I am afraid that I will not escape death. ”

One-on-one giants are difficult to deal with, let alone swarmed giants. A single person who spits at the mouth of the foam may drown a person. And you must always be careful to guard against the strange species of giants, armored giants, super giants, and so on. Although these giants have similar IQs to zombies, their combat effectiveness far exceeds that of Tongji, and they are not at the same level at all.

Just as the few people were about to leave, a deafening roar suddenly sounded not far away, and the anger contained in it made people's hearts tremble.

"It's a giant incarnated by Allen!"

"Look at the giant's feet, it's an adventurer!"

Hidden missions? Extremely daring! This was the first thought that appeared in Lin Xiao's mind.

At the feet of Allen, who has turned into a giant, there are three adventurers jumping and moving like projectiles, watching them put on a posture, but they want to kill our protagonist on the spot!
