"Hmm?"
Hearing a string of strange cries, Ye Feng couldn't help but roll his eyes and look up.
"So many monsters!~"
Almost at the same time, Xiao Xiao's worried voice sounded, and Ye Feng's expression was also not very good.
Because at this moment, all sorts of flying monsters were in the sky, screaming and preparing to attack.
"Zzzt~ Zzzt~!"
At this time, the walkie-talkie in Shen Potian's arms also emitted a sound.
Shen Potian frowned slightly, stuffed a piece of bread into his mouth in two or three bites, and picked up the walkie-talkie.
"Zzzt~ Bang~ Rumble~ Clang!~"
"Lord City Lord, Lord City Lord, a large number of mutated giant rats have appeared near the periphery of Mech City, it's a rat tide... and all sorts of monsters..."
"The rat tide and monsters are coming from all directions. If they pour into Mech City, the consequences are unimaginable. Should we go and intercept them?"
Shen Qing's voice came from the walkie-talkie, mixed with a lot of fighting sounds and monster roars. Shen Qing, Shen Bai, and others wanted to go and intercept the rat tide after killing a large number of monsters and rebels, but Shen Potian had specifically instructed them earlier not to go outside the periphery of Mech City, which was why he contacted Shen Potian via walkie-talkie... Even though there was a super explosion of nuclear bomb level at the City Lord's mansion before...
"Do not go outside the periphery of Mech City. Tell people to retreat and kill the monsters inside the city!"
Shen Potian glanced at the City Lord's mansion, which had already become a complete ruin, and quickly said to Shen Qing.
"Yes!"
"Zzzla!~"
Shen Qing responded and then ended the call.
Shen Potian's words made Ye Feng, Xiao Xiao, and Shen Yun Yao quite puzzled, because when encountering something like a rat tide, they definitely had to intercept it first. If a massive number of giant rats poured into Mech City, dealing with them would be...
Shen Potian didn't say anything. He gulped down the remaining half bottle of coconut water in his hand in one go, then walked to an open space, his eyes narrowed. Green light surged in his hand, and he began to form a seal.
"Teleportation formation?"
Seeing the seal Shen Potian was forming, Ye Feng was a little surprised.
As the green light in Shen Potian's hand flickered, the space in front of him quickly distorted, and then a square platform, carved with mysterious runes and somewhat resembling an altar, appeared in everyone's eyes, floating directly in front of Shen Potian.
"Drink!"
Shen Potian's expression was solemn. With a deep shout, he formed another seal in his hand and slapped it towards the altar platform in front of him.
"Buzz!"
Instantly, the entire altar platform erupted with light, and the mysterious runes carved on it also became active, flashing with light, and finally shot towards the sky.
"Zheng Zheng Zheng!"
Several deep sounds echoed continuously. It turned out that in many places within Mech City, light pillars were also erupting vertically upwards. These light pillars were also covered with mysterious runes, and the light at the top of the light pillars flickered and dispersed, then connected with each other.
Soon, the light emitted by the light pillars formed a huge formation, covering the sky above Mech City.
"Shu shu shu!~"
At this moment, the green light in Shen Potian's hand flickered again. The formation above Mech City shifted, and the light surged and expanded, finally spreading outwards from Mech City as the center.
"Crack~ Ah!"
"Zi~ Ge~ ! Ge!~"
The monsters above Ye Feng and the others were hit by the formation's light, screaming instantly and falling straight down. They stopped moving after hitting the ground, while some monsters sensed the danger and quickly flapped their wings and flew away.
The speed of the formation's light was very fast. Within a few breaths, it reached the periphery of Mech City and swept towards the rat tide and monsters surging from afar.
"Shu~ Hu~ Lu~"
"Zheng Zheng~~ Hu~!"
The formation's light swept through the rat tide and monsters. A large number of bared-toothed giant rats and monsters turned into coke. A few burrowed into the ground to hide...
"Zzzt Zzzt!~"
At this time, Shen Potian's walkie-talkie sounded again, "Lord City Lord, the rat tide has..."
...
On the other side,
A considerable distance outside Mech City, a figure wearing a camouflage cloak was looking at the scene with binoculars.
If anyone were present, they would be incredibly surprised, because this person's entire head looked almost exactly like a rat's head, even the whiskers were the same. If one suddenly saw it, they would think it was a monster walking upright.
"It failed... after preparing for so many years... such a grand occasion... yet it still failed..."
"As expected of a top expert since the beginning of the Great Cataclysm..."
The rat-headed cloaked man muttered, looking at the vast expanse of giant rats turned to ashes in the distance. "What a pity for my little darlings that I've cultivated for so many years..."
"But the battle just now... seemed a bit off..."
As his voice fell, a strange light flashed in the rat-headed cloaked man's bean-sized eyes.
...
On Ye Feng's side,
"Grandpa, just now... why did those monsters..."
Shen Yun Yao looked at the pile of monster corpses around her and looked at Shen Potian with a questioning gaze.
"It's the defense formation!"
As the light of the formation gradually dissipated, Shen Potian sat on a rock, his face pale, gasping for breath.
"Yao Yao, do you remember why I told you earlier that Mech City was built in this place with three sides open and almost no natural defensive barriers!"
Shen Potian took several deep breaths before speaking again.
"Ancient ruins?"
Shen Yun Yao immediately reacted, as Shen Potian had told her just a few hours ago.
"En!"
Shen Potian nodded. "The defense formation just now is part of these ancient ruins, named Annihilation!"
"You must have wondered why I value the Mech Star Hotel in the outer city of Mech City... and claimed that it was one of the earliest habitats when Mech City was first established, having special significance."
"Actually, it's because that place is a crucial part of Mech City's core defense, a vital pivot point for the Annihilation defense formation!"
"It's not just the Mech Star Hotel, the Secret Mech Institute, the palace building in Mech Plaza, and the wine cellar where I keep my wine... they are all important pivot points of the defense formation!"
"Although the Annihilation defense formation is immensely powerful, it should not be activated lightly unless in a life-or-death situation. After all, once activated, it takes a long time to be usable again..."
Shen Potian quickly explained to Shen Yun Yao.
"So that's how it is~!"
Shen Yun Yao suddenly understood. Many things that had confused her before became clear.
Afterward, Xiao Xiao took out more drinks and bread. The group ate and then silently found places to sit or lie down to rest, recovering their strength. After all, the intense battles where they had narrowly escaped death several times had left them exhausted, and they were too lazy to move...
"Grandpa, what kind of flame is on this Wutong wood sword? It seems a bit special!"
Suddenly, Shen Yun Yao's curious voice sounded.
...
