Ten minutes later.
Two more corpses of ferocious beasts appeared on the ground.
Since the ones who contributed the most were Little Tyrant and Mighty Bear, these two inner cores also fell into Wu Ming's hands.
At the same time, he also obtained a lot of evolution points.
The maximum mass of his black armor was one and a half tons. If he could add a part of it to Little Tyrant, it would definitely be a terrifying force.
Another twenty minutes passed.
Three more corpses of ferocious beasts appeared on the ground.
At this time, a bulletproof truck finally arrived near the park. Five people in blue combat uniforms jumped down from the truck. Each of them had an F-class wolfhound as their pet.
"Hello, H.e. Wu Ming. We are the Blue Helmets from the Mayor's Mansion. We are here to provide support under the orders of the mayor!"
The captain of the special forces nodded at Wu Ming.
Wu Ming had seen this person before.
Previously at the Mayor's Mansion, this person was wearing a black trench coat and sitting in the main hall as if he was waiting for someone.
At that time, Wu Ming did not pay much attention to it.
Only now did he realize that the captain of the special forces was pretending to be an ordinary person. In fact, he was protecting the Mayor's Mansion.
"The pets of the Blue Helmets are actually quintuplets of wolfhounds!" Wu Ming looked at the huge wolfhounds that were 1.5 meters tall. They were comparable to young bulls.
Each of them weighed at least three hundred kilograms.
Their eyes were sharp, their claws were sharp, and they were agile. They were good at cooperating and biting. If the five wolfhounds worked together, they could definitely kill the Tiger Python from before.
Even if it was a weaker E-class ferocious beast, they could still deal with it.
"That's right. Our pets are quintuplets. However, the members of our special combat team aren't. However, we're as close as brothers … Right, Sir Wu Ming, where's the underground passage?" The captain of the special combat team asked.
"It's here." Wu Ming pointed at the center of the park.
"The Blue Helmets will be the vanguard. Then, we will bring bombs and expansion materials inside to seal the passage." The captain of the Blue Helmets explained the battle plan.
"Expansion materials?" Wu Ming was surprised.
"I know!"
Wan Siyu stretched out her hand. "This material will expand when heated and spread crazily. After solidifying, it will be stronger than rock. It's a very good building material."
"So that's how it is!" Wu Ming suddenly understood. "Then, let's start now."
"Set off!"
The group of fourteen people took the bombs and several large wooden barrels and rushed to the underground passage.
Whoosh!
At this moment, a large group of pig-sized black iron-teeth rats rushed over here, uttering harsh shrieks.
"Fire!" Wu Ming shouted.
Little Tyrant immediately opened its mouth and spat out a blazing flame. This large group of iron-toothed rats that could bite through steel were all burnt to a crisp, emitting a pungent burnt smell. It was very unpleasant.
The group continued to venture deeper.
The underground passage was dark but dry.
There were also circles of digging marks on the walls, as if they were dug out by some kind of ferocious beast.
"Could it be that this passage is man-made?" Huang Sanba came up with this conjecture.
"According to the traces, this passage seems to have been dug out by some kind of earthworm and it has a history of many years," the captain of the Blue Helmets whispered.
"Many years?"
Everyone present felt their hair stand on end.
Could it be that the ferocious beasts outside the city had been plotting against Garan Castle for a long time?
If that was true, then the ferocious beasts were too intelligent.
"Humans are adapting to the changes and the ferocious beasts are evolving as well. We have to accept many things." Wu Ming exclaimed.
Along the way, they were almost unstoppable.
Of the fourteen pets, apart from Xiao Long and the Ponies, the others were all experienced or elite F-rank. Their comprehensive strength was quite strong.
Half an hour later.
They had reached the base of the city wall.
"We will use bombs to blow up the expanding materials here and catalyze them with high temperature. They will harden and block this place." The captain of the Blue Helmets placed several large barrels of materials in the middle of the passage.
"The bombs are installed. Let's go!"
Three minutes later, they hurried back.
Boom!
With a muffled sound, a small bomb exploded. The large barrels of expanding materials reacted to the heat and began to expand rapidly, filling up the passage.
"Blow up the passage in the city as well!" Wu Ming suggested.
"Okay." The captain of the Blue Helmets took out the remaining bombs and installed one every one hundred meters.
Boom!
With a loud noise, the underground passage collapsed.
Everyone was relieved. They went back to the ground, took off their masks, and gasped for breath.
"Now, the city should be safe." Huang Sanba lay on top of Zuma Mei and grinned.
All of a sudden, Wu Ming stood up and looked into the distance. He noticed that there was a lot of dust in the city as if something was breaking out of the ground. His eyelids twitched.
"No, there may be more than one underground passage!"
Wu Ming's expression changed.
The others trembled and stood up at once.
Boom! Boom! Boom!
The mayor's heavy voice came from the nearby broadcast. "Attention all citizens, there are eight underground passages dug out by the Grade-F Direbeast, the Burrowing Earthworm, in the city. The total number is eight. Citizens of the lower city districts, please take shelter as soon as possible!
Qingyun District, Park District … "
"There are seven more underground passages!" The captain of the Blue Helmets punched a tree.
Everyone's expression was not good.
Dealing with one underground passage already required so many people. Now that there were seven more, what should they do?
Ring ring ring!
The captain of the Blue Helmets's phone rang.
"Hello, it's the mayor … Don't worry, we've dealt with the underground passages in the Park District. We'll go to the other districts … Don't worry, H.e. Wu Ming is safe … Okay, we'll go now!"
The captain of the Blue Helmets hung up the phone.
He looked at Wu Ming and said, "H.e. Wu Ming, we'll go to the nearest underground passage and use the previous method to block the way."
"Let's go together!" Wu Ming said.
The more people there were, the safer it would be.
Besides, everyone present was very experienced. Their cooperation just now had been successful. If they worked together, they could almost sweep through everything.
"Okay!" The captain of the Blue Helmets was happy.
Soon, everyone jumped into the bulletproof truck and rested inside.
"Here, eat some ordinary food to recover your strength," Wu Ming took out a bag of ordinary food that looked like dog food and fed it to Little Tyrant.
These ordinary food contained abundant energy. While it could not help a pet evolve, it could replenish its strength.
Little Tyrant was not big in size. After a few bites, it recovered most of its strength. After drinking some water, it lay in front of Wu Ming. Its two big eyes would peek at him from time to time. It looked very funny and adorable.
Whoosh!
The bulletproof truck came to a sudden stop. Everyone almost fell into the truck.
"What happened?" Wu Ming quickly asked.
"There's a situation. The road ahead is blocked … There are five Grade-F beasts wandering around. Oh no, there's also a Grade-E beast!" The captain in charge of driving was shocked.
Everyone was shocked when they heard this.
