The Spirit Bone Strider Bird was somewhat similar to an ostrich, but its body was long enough to seat two people.
Its long neck slightly obstructed vision, swaying back and forth in front of Zhang Chen.
Fortunately, the Strider Bird was a special transportation-type spirit beast with no offensive capabilities, and it could move according to the owner's thoughts, automatically avoiding obstacles.
So, it didn't matter if Zhang Chen didn't watch the road.
Soon, the Spirit Bone Strider Bird entered the area where ancient battlefield spirit beasts often appeared.
The so-called ancient battlefield was not a battlefield on a plain, but a former super city.
This city once had fifty million residents and a vast area.
It was said that driving from one end to the other would take over two hours, and if there was traffic, it might even take a day.
People living at opposite ends of the city might never meet in their lifetime, and their lives had almost no intersection.
However, spirit beasts specifically appeared in such densely populated cities, instantly turning it into a living hell.
Later, ancient spirit masters and spirit beasts engaged in tens of thousands of battles here. Although the strongest spirit beast commander was eliminated, humans never had the ability to completely subdue it.
To this day, it has become a training ground. It is rumored that powerful ancient spirit beasts slumber beneath the city center.
Of course, it is also rumored that there are many weapons and equipment left over from ancient wars, as well as precious spirit beast bones, fur, and other materials.
This is also why many people are willing to risk entering here.
"Powerful spirit beasts have nothing to do with me, we'll just kill some low-level spirit beasts to make some money!"
Zhang Chen said.
"Meow!"
At this moment, Mo Ran also jumped out of the backpack, wearing a combat suit and sitting behind Zhang Chen.
She hugged his waist with both hands, stretched her neck, letting the wind mess up her hair.
"Right here!"
Zhang Chen looked at the map. This was the area closest to the interior on the outskirts of the ancient battlefield.
There were more Tier 2 spirit beasts here, and occasionally Tier 3 spirit beasts would appear.
"I'll scout around, you're responsible for protecting me!"
Zhang Chen said to Mo Ran.
"Meow!"
Mo Ran nodded, took a few quick running steps to the side, then jumped onto a concrete pillar with exposed rebar.
The air around them was filled with powerful spiritual energy, affecting the effectiveness of Absolute Sight.
He could only vaguely see a few spirit beasts behind the nearby walls. The energy surging from beneath the ground was exceptionally strong, as if a large number of spirit beasts were below.
"Subway station?"
Zhang Chen stood in front of a rusty metal sign, wiped the dust off it, and read.
"What's a subway? Should we go down and see?"
Zhang Chen looked at the dark subway entrance, which resembled the mouth of a giant beast, as if it were about to swallow everything.
"There are many spirit beasts down there, be careful, don't be too careless!"
Zhang Chen gently patted Mo Ran's back and said.
"Meow!"
Mo Ran nodded, leaped forward lightly, and silently entered the darkness.
Cat's eyes were naturally able to see in dim light, so entering the darkness caused no discomfort at all.
Zhang Chen soon followed down the stairs, step by step.
The entire underground passage was filled with a foul, moldy smell, which was very unpleasant.
At first, Zhang Chen's vision was very dark, but he quickly adapted. With the enhancement of Absolute Sight, it was as bright as daylight.
He saw black bloodstains everywhere on the ground, the floor tiles were all shattered, and in some places, there were deep, bottomless holes.
A few ugly Tier 1 spirit beasts were wandering in the hall. As soon as they discovered Zhang Chen, they were instantly killed by Mo Ran, turning into wisps of black smoke.
"Subway, is it an underground train station?"
Zhang Chen slowly walked to the subway platform.
To his left was an abandoned subway train. Spirit beasts occasionally walked slowly inside the carriages.
Some spirit beasts were like lunatics, tilting their heads, mumbling to themselves.
Others ran around frantically in place, hitting the walls with their bodies from time to time.
One spirit beast's body was almost hollowed out by another spirit beast, but it still stood there without any reaction, a sinister smile on its face.
Low-level spirit beasts lacked intelligence; they were merely bloodthirsty zombies.
Before Zhang Chen could give an order, Mo Ran quickly rushed into the carriage and, one by one, easily eliminated these Tier 1 spirit beasts.
Then she grabbed a large handful of spirit cores and handed them to Zhang Chen.
"Good job, keep going, I'll just wander around!"
Zhang Chen opened the map of the ancient battlefield outskirts. There was a treasure chest icon, very close to his location.
Why not go and see?
