After the battle plan was finalized, everyone prepared overnight, and everyone put on the professional equipment provided by Black Steel.

Out of consideration for the possibility of someone losing control, Brother ACE specially selected a combat uniform with strong fireproof and high temperature resistance for everyone.

At the same time, the equipment to prevent source stone substances is also readily available.

The Snow Monster Squad is also fully equipped with various equipment, each of them is equipped with an anti-jamming military communicator, and at the same time carries a large number of finished source stones.

...

Xia Feng immediately communicated the battle plan with the Black Steel, and Ogul's response was very righteous.

Ogur said that he would let Franka and Razer fight as members of the Black Feather, and that it would not affect anything.

Then, although Blacksteel's main forces in Colombia were unable to provide substantial support by force due to various factors, he would have manned the operation to ensure the closed nature of the operation.

In other words, the men of Black Steel will block all support routes on the perimeter to prevent Rhine from intervening in the course of the battle.

Of course, this probability is very small, and Rhine Life will not let its dark experiments be exposed.

Once the military intervenes, many soldiers will see the terrifying Source Stone Beast, and this news is difficult to block no matter what, and it will cause a chain reaction of public opinion among the people at that time.

However, it is not excluded that the Rhine Life Dog jumped over the wall in a hurry, and forcibly asked the military to intervene.

So the combat units of Blacksteel will prevent this from happening, Blacksteel knows the distribution of the Colombian army very well, and they will intercept it on the periphery under various names, such as exercises, investigations, all kinds of misunderstandings, etc.

Black Steel can be regarded as solving Xia Feng's worries, as long as the military's intervention action or intervention time is blocked, the rest is to wrestle with Rhine Life head-on.

....

4 a.m.

The sky was just white, and the wilderness was filled with white morning mist.

Two large military vehicles set off from the Black Steel base and went to the ruins of the city of Buda, which is more than 80 kilometers away, which is the No. 4 experimental base of Rhine Life.

A few hours later, it was completely light, but the sky was overcast and terrible because of the dark clouds.

"Squeak!"

The vehicle was parked in a bush, less than 1 kilometer from Experimental Base 4, and was to be kept on foot in order to ensure the integrity of the vehicle during the retreat.

The outer intersections have been ensured by the scouts of Black Steel that there are no outsiders and no need to worry about the back, their target is only the steel fortress in the desert ahead.

After getting out of the car, Xia Feng pulled out the Shenyue Knife and held it tightly in his hand.

"Attention everyone, the action begins!"

Glancing at the frost star who was ready to go, and everyone's resolute expressions, Xia Feng said in a deep voice.

"Our main task is to contain and create opportunities for Froststar, remember not to attack blindly, leave the tricky enemies to me to deal with."

"Yes!"

....

After advancing a few hundred meters, the team led by Meteorite left the large force and went around to find a suitable long-range fire suppression point.

This is a hillside, and although there are no overgrown plants, it has the advantage of a high and low field of vision, and the effect of ranged weapons will be very good.

After 5 minutes.

The large army walked down the hillside and stood still, Xia Feng looked ahead with a gloomy face, less than a hundred meters ahead, the reconstructed No. 4 experimental base stood impressively.

Nine months ago, it was the cage where he had been kept like a domestic animal for a long time, and finally, it turned into a sea of fire.

And now, the cage rises again, and imprisons the people who once helped him get out of the cage.

This time, he's going to open the cage from the outside in.

....

The clouds in the sky had thickened, the wind in the air had disappeared, and a storm in the wilderness seemed to be brewing.

At the foot of the hillside, everyone was ready for any mutation, and Summer Wind and Frost Star glanced at each other and nodded slightly.

"Froststar, please."

"Leave it to me."

The white squad broke away from the large group and quickly moved down the hillside to the flank, looking for an entrance suitable for a forced breakthrough.

After watching Frost Star and the others walk away, Xia Feng knew that they had to make a move.

"Ding!"

The Shenyue Knife flipped and rested on the palm of his hand, as long as this knife went down, the black power of the 28th day would be drawn out.

Seeing Xia Feng's movements, everyone raised their weapons and prepared to attack.

"Buzz Bum ~"

At this moment, there was a sound of air shaking above, and a small drone was hovering about 20 meters above.

Sure enough, they had already been discovered.

"Bang!"

Razer raised his hand and shot down the drone decisively.

The crisp sound of gunfire rang out in the wilderness, like a signal of the start of war, and the huge base ahead, followed by the roar of machinery running.

"Bang!"

A loud bang, several times heavier than a gunshot, was heard at the top of the base.

With this loud bang, a glowing fireball shot quickly towards Xia Feng and the others.

A blue barrier instantly appeared, blocking everyone.

"Boom!"

The strong explosion seemed to explode against Xia Feng's face, but he was unharmed.

The turtle turtle carried her backpack and held a source stone in her hand, and her protective shield was released in a timely manner.

Looking at the source of the loud noise, at the top of the base, a black cannon muzzle was facing them, this was the "city cannon"!

...

In the world of Terra, things like the city guard cannon are rare positional defensive weapons, and as far as Xia Feng knows, only the walls of the Dragon Gate seem to have such things.

Several times more complex than the source stone to construct and control, it is an extremely rare and unpopular technological weapon in the world of Terra, and is generally only equipped in large independent city-states.

In Terra's current Source Stone technology system, this is a high-tech weapon with a very high threshold, huge investment, high cost, and very low returns.

This "guard cannon" will be very advantageous only when the enemy besieging the city does not have the means of long-range strikes and is slow in action.

But it's a pity that long-range strikes, summer winds also have them.

...

Seconds after the fire of the cannon, a muffled sound was heard on the hillside.

A mortar-like shell was angled upward, hoisting a source stone projectile in a parabola towards the city cannon.

"Bang!"

The explosion exploded on the moat, and although it was much weaker, the precise angle and strong explosion still distorted the muzzle of this cannon by half a point.

Obviously, this is the Meteorite's source stone cannon crossbow, and it is estimated that only she can play this heavy weapon with a very limited range into a parabolic mortar.

...

The threat of city defense artillery has been lifted for the time being, but it cannot be ruled out that there are other angles of artillery on this huge base.

"Everyone disperse, pay attention to the sound of artillery and dodge in time!"

"Yes!"

The two guns were counted as their own greetings, and then the ground below Base 4 shook.

"Boom!"

The ground cracked, the ground shifted, and at the front of the base, dozens of wide gaps were opened in the ground, as if opening a passage from the ground to the surface.

Xia Feng stared at these cracked gaps tightly, and then, various giant beasts that exuded source stone energy appeared one after another.

Looking at these creatures that are not strangers, Xia Feng said in his heart, sure enough, he has this hand.

...

At this time, what poured out of the underground gap was a terrifying biological weapon that Rhine Biology had never disclosed to the public, the Source Stone Beast.

Source Stone Beasts of various forms let out low roars, pouring out from dozens of gaps, and there were more than a hundred of them.

The overwhelming source stone energy seemed to turn this place into a natural disaster area, and the air was filled with heavy source stone substance.

"Huh!"

The Shenyue Knife brought out a blood mark, Xia Feng cut through the palm of his hand, and black flames instantly appeared in his pupils.

In the face of the source stone beast with a terrifying breath, none of the companions around him flinched.

...

The blazing heat came from behind her, and Ifrit stared at the massive base in front of her, the air around her already distorted by the heatwave.

The source stone in his hand quickly turned into black coke.

"Smack!"

The source stone that had lost its luster was crumpled into pieces by her, and the next moment, the endless anger hidden in the flames had even overshadowed the ability emanating from the source stone beast.

[The last wish in the blazing heat turned into an endless flame, born in the flames, and ended at the apex of boiling. 】

In ancient times, the wrath of the Flame Djinn was sealed within her.

When the Inheritor regains his true emotions and emotions are truly angry, the flames of the Flame Demon can burn all things in the world.
