Under the heavily armed escort of the Trident troops, Han Yan took Xia Qiluo, Shen Fei and others into the Hidden Dragon Gate.

At this time, there are already people waiting.

Seeing Han Yan and their appearance, a young man in formal clothes stepped forward and said, "Commander." ”

This person's name is Lu Yuan, and he is the caretaker of the Eastern Star Gate.

"Well, open the stargate!"

Han Yan nodded and said with a serious expression.

For more than two years, he has gradually become familiar with his current position.

So unconsciously, he also has the unique temperament of a certain superior.

"Yes!"

Seeing Han Yan, Lu Yuan's originally flustered heart gradually calmed down.

As he spoke, he took a piece of crystal from his bosom and placed it in an instrument.

With the appearance of a pillar of light, a stargate slowly condensed and formed.

The scene is like a circle of "Doctor Strange" in a Hollywood movie, which is very magical.

"Let's go."

Han Yan looked at Xia Qiluo and the others, and then waved his hand and led everyone into it.

......

The Underworld, a magical otherworld.

Unlike the earth, the earth has been almost reclaimed by human beings.

But in the Dark Realm, it took decades of excavation for humans to reclaim a small area.

Within this small area, humanity has built its own mega-cities to resist the invasion of some terrifying beings.

There are a total of five cities built by Hua Guo in the Underworld, corresponding to the five major war zones.

Each city is home to more than a million genetic warriors, who are tasked with exploring and excavating and gathering information about the Underworld.

They are explorers and defenders.

When the enemy invades, they turn into strong walls to keep the enemy firmly out, because behind them is their homeland, the home on which all people depend.

The opening of the stargate brought humans into this magical world, allowing people to gain power comparable to that of gods, but at the same time, it also exposed the humans themselves, because the stargate itself could not be closed.

The Bone Beast, this is the greatest enemy that humanity has encountered on this side.

These ghosts will appear in groups at certain times, and the cities built by humans are the first targets for them to attack after they appear, and people name them Bone Beast Tide.

In these decades of exploration, human beings have fought countless battles with bones, and they can be described as suffering heavy casualties.

But I still don't know how these guys appeared, they seem to appear out of thin air, they come and go without a trace, and the source cannot be traced.

Tianhe City.

A city belonging to the Eastern Theater of Operations.

It is also where the frontal impact of the bone beast tide lies this time.

Tianhe City has a resident army of 3.6 million, and its combat strength is among the best among the five major theaters.

In the past, the Eastern Theater faced the Bone Beast Tide, and it was all at ease.

But this time, people are worried.

The reason is that the commander-in-chief of the theater of operations has just died, and the new commander-in-chief is said to be still in the awakening stage, and even his own genetic lock has not yet been opened.

The old and the new alternate, and this is precisely the most vulnerable period in the Eastern Theater of Operations.

Originally, according to the predetermined plan, it should take more than half a year for the appearance of the bone beast tide.

In three years, according to normal speaking, Han Yan's gene lock should also be opened.

But unexpectedly, the Bone Beast Tide suddenly appeared, and as if they knew their situation, they went straight to Tianhe City as soon as they appeared, which caught everyone off guard.

Did Han Yan awaken the gene lock?

Do you have complete control of the key to unlock the core of the genetic chain?

In the hearts of today's Tianhe City garrisons, everything is unknown.

If the answer is yes, then they have the strength to fight against the Bone Beast Tide.

But if the answer is no, then ......

To be honest, everyone didn't dare to continue thinking about it.

"Stomp ...... Stomping ......"

The earth was trembling, and dust was flying at the end of the sight.

Fierce beasts the size of tigers run fast, and they are in groups, like the scene of a gluttonous attack on the city in some movie.

They are called bone beasts because their bodies are covered in hard skeletal armor and secretly numb bone spurs.

His eyes glowed blue, and there was a flame in his skull.

In terms of image, these things are more like amplified versions of wolves.

On the tall walls of Tianhe City, dense soldiers stood straight, wearing standard black military uniforms and holding black long knives in their hands.

This equipment was specially created for the Warriors of the Dark Realm.

In the face of the Bone Beast, the effect of the human thermal weapon is very limited.

And this special cold weapon, known as the Black Crystal Weapon, can cause effective damage to the bone beast, but the premise is to release the gene lock energy.

Without the blessing of genetic energy, Sombra weapons are no different from ordinary scrap metal weapons.

The key to releasing genetic energy is in the hands of the commander-in-chief of each major theater, so to speak, at this moment, the strength of the commander-in-chief of the theater determines the life and death of everyone, and determines whether the star gate can be guarded.

If the city is attacked and the stargate is lost, then the earth will become a hunting ground for the bone beasts.

Of course, the earth itself also has its own defense power, but I don't know if this power is useful for bone beasts, because no star gate has been lost so far, so there is no way to confirm whether this defense system is feasible.

Whether it is feasible or not, the battle to defend the city must be carried out.

Since people chose to enter the dark world in the first place, they must have this kind of awareness.

After all, to a large extent, the act of human beings entering the dark world is also an invasion, and the survival of the fittest is the survival of the weak, even if the earth is occupied by other more powerful species, it is self-inflicted.

......

The beast tide surged, like a mudslide in the desert, gradually approaching Tianhe City.

Tianhe's defense system is divided into external and internal.

The exterior refers to the city wall, which is nearly 100 meters high, and the city wall inlaid with a large number of black crystals is the external barrier of Tianhe City, which can effectively block the impact of the bone beast.

In addition to exploring and developing in the dark world, human beings also have a mission to find Sombra.

This peculiar spar, which can be made into weapons and can strengthen defenses, is a substance unique to the Underworld.

However, this thing is very rare, and it can be regarded as a strategic-level material.

If it weren't for the advent of the Bone Beast Tide, it would be impossible for Tianhe City to open its arsenal to each person.

In normal times, when the fighters go out on a mission, each squad is equipped with a maximum of one Sombra weapon, and they must hand it in every time they come back, and if they are lost, they must write a review report explaining the reason.

"Roar, Roar, Roar, ......Roar, Roar, Roar, Roar, T

The tide of bone beasts approached, and people stood on the city wall and looked down, and they could see the ugly faces of these monsters.

Greedy, bloodthirsty.

There is no emotion in their gaze, they are pure killing machines.

One can imagine what kind of damage these guys would do to the peaceful world over there if they rushed into Tianhe City and entered the Star Gate.

"Release the Gene Lock!"

In front of the crowd, a famous general began to release the genetic lock, and as they moved, all the soldiers were released at the same time.

It can be seen that people have their own genetic locks behind them at the same time, red, blue, and white are different, and the only thing that is the same is that these genetic locks are all hung on the huge galactic chains.

After doing all this, everyone stopped at the same time because their mission had been accomplished.

The rest of them can only wait in silence, waiting for the lock to be opened.

Or can't be opened.
