Evening.

Sunset.

It's a rare day in the wasteland, with the wind blowing from the grasslands in the distance, mixed with the yellow-green glow of the sunset, projecting on the wilderness outside the "Maze of Machines".

The black-robed woman who had subdued Chen Mu with a move before was lurking here at this time.

Or maybe it's not lurking, because she doesn't look like she's hiding, but stands generously on a small hillside, as if admiring this rare sunset.

In fact, this is not a small hillside, the entire "mechanical maze" is a huge ancient ruin, and the current city is only a small part of it.

And the large area on the outskirts, almost all the places that are not covered by wild grass, that is, the bare wilderness, are almost part of this ancient ruin.

This hillside is no exception, although it is hidden by the cracked soil, it looks like an ordinary small mound.

But as long as you dig up the outer layer of soil, you can find that there is an intricate pipe network underneath, and from here, you can enter the underground part of the ancient ruins, that is, the underground city where Chen Mu and the Crimson Mecha are located.

The black-robed woman obviously knew about this, because on the back of the hillside, in the shadows that could not be illuminated by the sun, a small hole had been dug to reveal the bottom pipe network.

The entrance to the cave was slowly emitting a stale smell, waiting for clean air from outside to pour in, or for the air pressure in the pipe network to rebalance, so that the interior of the dungeon would not be easily noticed.

From this small detail, it can be seen how cautious the black-robed woman is, even if it is abandoned for countless years, for the huge dungeon, it is simply inconspicuous, and it is almost impossible for anyone to find any airflow anomalies.

Not to mention that it is just such a small hole, even if it is dug a little bigger, or even a few more holes, it is unlikely to cause any abnormal airflow, because in the entire dungeon, there are no less than hundreds of large entrances and exits and exhaust holes, which can be described as air leaks everywhere.

But even so, the woman in the black robe still took into account all possible mistakes, and she is this kind of character who has no last resort.

In fact, she herself knows that there is no last resort, even if she has considered all aspects in advance and imagined all possibilities, it is still difficult to guarantee that there will be no unthinkable emergencies.

For example, this is the case this time, everything was originally planned, and even if there was any accident, she had all kinds of backup plans.

Even including the ghost clan and the demon clan, she also considered it early, even if this is still the territory of human beings, even if the other party has at most planted some spies, it is impossible to make big waves, she still has considered it, and has a corresponding plan.

But the ending was far beyond her expectations, and the ghost clan didn't know where to get such a strange and terrifying method, and quietly turned the entire city into a dead city.

You must know that this is not a "mechanical maze" in a daily state, at that time it was just an ordinary grassland city, and the defense force was not very strong.

However, since the army of the king of the mountain occupied this place, the city has become one of the important logistical transit points of the army, not only the implementation of comprehensive military management, but also the defense of all aspects has been greatly strengthened.

Besides, even the son of the king of the backer lives here temporarily, no matter what the physical condition of the king of the backer is now, and how fierce the power infighting of the Yang family is, Yang Tianyuan is still the son at least for now.

Coupled with the current dangerous situation of power infighting, it is even more impossible for Yang Tianyuan's side to lack protective power.

But it was in such an absolute impossibility that the "Mechanical Maze" easily fell, Yang Tianyuan's whereabouts were unknown, his life and death were unknown, and the entire area around here was not half a living thing, full of strange negative energy.

At the time of the incident, the black-robed woman was also in the city, and she was not alone on this trip, and there were also bright or dark entourages around her, among which there were also masters, not much worse than Yang Tianyuan's situation.

It was precisely because of this that she knew how terrifying the power used by the ghost clan this time was, and no one around her escaped from the city alive.

Even if it is the strongest master among them, it is already infinitely close to the existence of a transcendent martial artist, and it is the limit of the strength that the Little Black Tide District can tolerate, and under the attack of that weird negative energy, it has not been able to escape.

In fact, the woman in the black robe herself has experienced it herself, and for those weird negative energies, Ou Qi doesn't seem to have much effect.

Even if it has an effect, it is minimal, and it consumes a lot to resist, while those negative energies seem to be endless.

What's even more disgusting is that within the scope of this weird negative force field, you can't move fast at all, and you can't fly into the air at all, otherwise the faster and higher the altitude, the more negative energy will be attracted.

The strongest master beside her was the only one who could fly a distance of 100 meters at that time, and he also protected her with his life, throwing her to the edge of the city as much as possible, but he couldn't escape.

Of course, the woman in the black robe knew very well that even if she didn't protect herself, the other party would not be able to withstand the endless negative energy attacks, at most, she would run an extra distance, but it would be impossible to run out of the city, so the ending would not be different.

The reason why she was able to escape was because of a life-saving item on her body, a Sky Dynasty relic excavated from ancient ruins, which could infuse the user with a massive amount of vitality for a period of time after use.

If the monkey were here, they would definitely recognize this thing, it was the "Seventh Generation Rapid Cell Regeneration Elixir", which was also more precious during the Sky Dynasty period, and it was also called the "No. 7 Holy Water" at that time, and it was a treasure that could prolong life.

This thing is also a disposable item, and it is by relying on this thing that the black-robed woman escaped from the city without danger.

However, compared to the big killing weapon activated by the monkey gang ghost clan, this "No. 7 Holy Water" is also an ordinary medical item.

And the big killing weapon that can release a weird negative force field is a serious war-level item, and it has not been used a few times in the entire history of the Sky Dynasty, until the invasion of the Outer Heaven Demon Race, and the human race broke the cauldron and fought against the water, and this kind of big killing weapon was used.

The full name of this thing is very long, very complicated, and it also involves some black technology content, which is almost impossible to describe, and ordinary people can't understand or remember it at all, so during the Sky Dynasty, most people who knew about this thing liked to call it "death declaration".

As a one-time war-level mass killing weapon, the "Death Declaration" is very, very rare even in the Sky Dynasty, and most of it was used in the Battle of Dusk.

I didn't expect that the Sky Dynasty had been wiped out for so long, and the ghost clan could still dig up a piece of this thing, and also met a fire monkey who knew how to activate it, and it was really unparalleled.
