The train had traveled some distance and entered the tunnel again, the light dimmed, and there was a thumping sound on the roof of the train.

Through the car window, Wen Ya saw more than a dozen black shadows jumping and sliding in the tunnel, these mutated animals with bodies like wild dogs and heads like bats, with red eyes open and wings on their backs, and four paws stuck to the car window, looking at Wen Ya.

"This is a mutant bat dog, a perfect combination of a vampire bat and a fighting dog, with the nocturnal characteristics of a bat and the agility of a dog, and is the most numerous, mutated creature on this route." The black crow took a sip of wine and explained calmly.

"The windows are of good quality."

"The raw materials used in the "subway" are specially used to defend against these synthetic mutant animals, if these mutant bat dogs run outside, their combat effectiveness is not ordinary, and a mutant bat dog kills the kind of train just now, and there is no pressure on a car of people."

"These mutant bat dogs shouldn't be able to get out." Wen Ya had just noticed that the farthest distance that these mutant batdogs could reach was at least fifty meters away from the exit of the tunnel.

At that distance, it was as if there was an invisible prohibition that made it impossible for the mutant bat dog to move forward no matter how hard he tried.

"That's a good point, but who knows when the mutant bat dogs will be able to get out." The crow replied.

"You don't know why?" Wen Ya asked.

"I don't know, I was mixed with the alien organization for ten years before I got the qualification to deliver goods, and I only had the opportunity to contact Lou Xiaobing in these two years, and I got some information about the cloning laboratory through Lou Xiaobing."

As the black crow and Wen Ya were talking, the train driven by the old cow suddenly accelerated, and then suddenly braked, and the strong inertia almost threw the black crow and Wen Ya out.

"Old Niu, what's the situation?" Raven asked through the train's built-in intercom.

"Brother, we may be in trouble, there is a big guy on the roof of the car, I suddenly accelerated and braked suddenly, and this thing was not thrown off." Lao Niu replied anxiously.

"Made, it can't be that thing." The crow took a sip and pulled a long knife out of his bag.

At this time, there was a loud banging sound on the roof of the car, and Wen Ya clearly saw that the roof made of special materials appeared obvious bumps with the sound.

"Lao Niu, give Lao Tzu to drive quickly, and don't stop at the fastest speed, no matter what happens." The black crow's face changed and he commanded loudly.

"Okay, good," the old cow trembled a little in his voice, and then the train started slowly, and then drove forward at maximum speed, and the monster on the roof was not affected in the slightest, but made a louder noise.

"What's on the roof?" Wen Ya asked.

"If I guessed correctly, the monster on the roof of the car is an artificial and natural mutated alien, and the luck of the two of us today is really back." After speaking, the black crow poured a large gulp of wine and held the long knife in his hand.

"If this alien monster doesn't give up, the two of us will have to fight it to the death."

After speaking, the black crow pressed an inconspicuous button on the train, and a layer of steel plates rose up in the carriage, tightening the surrounding of the carriage.

Wen Ya took out the shotgun, vigilant about the movement around the car, the speed of the train was fast, and the acceleration and emergency braking did not throw the monster on the roof down, which was enough to show how strong the monster on the roof was.
