For several days in a row, Chen Hang and Lu Lili were observing the movement of this zombie, and they found that the footprints of the big zombie spread all over the Rocky Mountains.

The eighth-level zombie is indeed regaining its intelligence, Chen Hang noticed that it has learned to make fire, and this zombie has begun to know how to remove hair after catching birds, and it likes to wash its food in water before eating.

After several days of observation, Lu Lili judged that the intelligence of the zombie was about four years old for ordinary humans, and it was not very smart, and its memory was still a little problematic, which was the reason why it remembered that family after two years.

But even so, it was very scary to have an intelligent zombie, and Chen Hang and Lu Lili saw with their own eyes how it designed to kill a mutant bull.

Although the strength of this zombie was enough to crush the bull, when the zombie proudly hung the bull with a rope noose, Chen Hang was simply a little stunned.

"It's dangerous, and if you keep it growing, I'm afraid it will grow into an invincible overlord."

"You want to kill it? But it's helping that family! ”

"It's just a remnant memory in its head, it's a zombie after all."

"Anyway, I'm against harming such a human zombie."

Lu Lili uncharacteristically expressed resolute opposition, and Chen Hang had no choice but to give up, and they watched the zombie enter a city for the first time.

Phoenix is the capital and largest city of Arizona, as well as one of the largest cities in the United States.

Phoenix was registered as a city on February 25, 1881, when Phoenix was called Hoozdo in the Navajo language, meaning hot place; Known as Fiinigis in the Western Apache language. Phoenix is located on the banks of the perennially dry Salt River.

At its peak, with a population of about 1.5 million, Phoenix was the sixth-largest city in the country in the official census, but demographically it has surpassed Philadelphia to become the fifth-largest city in the country.

Phoenix was once home to a thriving Native American civilization, and around 700 A.D., the Hohokam civilization of the Indians developed in the area where Phoenix is located today, digging about 135 miles (217 kilometers) of irrigation canals to turn the area into arable land. Some of these irrigation canals were located in the same location as the Arizona Central Canal Aqueduct today.

During World War II, Phoenix relied on the military industry and quickly transformed from a logistics center to a new industrial city.

The U.S. has three military bases here – LukeField Air Force Base, Williams Field Air Force Base, Falcon Field Base and Hyder Training Base – bringing many new populations to Phoenix.

Chen Hang and Verelle have been to Phoenix City many times, and among the information they have learned, Phoenix City is one of the cities that humans have been holding on to for the longest time. The residents of this place fought against the zombies together with the soldiers of the base, and it was not until five years ago that the place was completely engulfed by the virus.

Coming to Phoenix again, Chen Hang noticed the changes in the city, which had been buried in time.

The ruins of the past were covered with vegetation, the artillery-smeared ground was buried in dust, Resistance tanks were littered, and the helicopters stuck upside down in the distance were rusty.

The Great Zombie was clearly familiar with the environment, and it skirted the crumbling walls, passed the abandoned station, and finally came to the entrance of a subway.

The entrance to the subway is buried in a handful of loess, and if you don't pay attention, you'll mistake it for nothing more than an abandoned pothole. The zombie removed one of the covers, and stooped into the passage.

Chen Hang and Lu Lili were suddenly surprised, they didn't understand what the zombies were doing when they entered the subway. The two waited outside for a while, then cautiously followed.

Entering the passage, it was filthy everywhere, the walls of the passage were covered with blackened handprints, and layers of bullet casings were laid on the steps.

After passing through the passage, Chen Hang and Lu Lili arrived at a place twenty meters underground, which is the subway system of Phoenix, and the spacious platform can show the prosperity of the year.

The big zombies have long disappeared here, and the subway tracks are empty. There was no light here, and the depths of the tunnel were pitch black.

The darkness did not affect Chen Hang and Lu Lili, and the two noticed the footprints in the waiting area. The footprints of the big zombie are very eye-catching, and it stretches all the way into the tunnel.

Chen Hang and Lu Lili glanced at each other, and the two followed the footprints into the tunnel, and they followed the track into the depths of the tunnel.

After walking for twenty minutes, the two saw a second waiting platform. This is supposed to be a platform somewhere, where the footprints have been boarded.

Chen Hang and Lu Lili followed, and they found that the underground station was smaller. Compared to the previous station, this station is much cleaner, and most importantly it has no exit to the ground.

It's strange that the station is designed underground, but there is no road to reach the station, how can there be such a design in the world?

Chen Hang and Lu Lili felt strange, and the two walked around the station, and they were surprised to find that the giant's footprints had suddenly disappeared.

Just as Chen Hang and Lu Lili were carefully searching, suddenly there was a "click", and the waiting area was full of light, and the light bulbs that should have been bad suddenly all turned on.

The sudden light caught Chen Hang and Lu Lili off guard, their pupils couldn't adapt to the sudden bright light at all, they covered their eyes at the same time, and they all entered a state of alert.

"Who are you, and why did you come back with George?"

A female voice came from behind the two of them, and the female voice was very flat, but her voice was full of endless majesty.

Chen Hang and Lu Lili quickly adjusted their perspectives, and they looked at the light. I saw the big zombie and a gray-haired woman standing at the end of the waiting area, and the big zombie was glaring at the two of them.

"Again, why are you following George?"

The woman asked again, and the big zombie took a step forward, and a powerful coercion suddenly came to her face.

The woman patted the big zombie's calf, the big zombie seemed to obey the woman's order very much, it lay down next to the woman, but the big zombie still maintained vigilance.

Chen Hang smiled, and he said to the woman:

"We just stumbled upon this mutant, and we were curious, so we followed, not expecting it to be with you."

"Lie, you're mutants too, George knows you've been following him for days."

The woman's face was actually young, but her hair was already white, and the woman's expression was serious, but Chen Hang always felt familiar with her.

Seeing that the woman was angry, the big zombie stood up again, and it took an attacking posture, Chen Hang and Lu Lili suddenly became a little embarrassed.
