A roar came from inside the office, and a sharp short axe slashed past Su Xiao's head, and several black hairs were cut off.

At the same time that Su Xiao leaned over, he kicked Buck's lower abdomen, and as soon as Buck retreated, a knife flew towards him.

Bite!

The blade was shattered by the blade of the axe, dissipating into the air.

"Whew~"

Su Xiao breathed a long sigh of relief, his breathing was slightly short, fighting an enemy like Buck consumed a lot of physical strength, every time he blocked those two short axes, he would be cut back a few steps, and after many times, the internal organs in his chest began to ache faintly.

Buck was also uncomfortable, he was covered in blood, the dragon slash was too sharp, and being lightly slashed was a deep wound that could reach the bone, a slash of normal force, that is, a cut of which one was broken.

Su Xiao and Buck looked at each other, and the two just wanted to fight together again, when the ground under their feet suddenly shook, this was not the first time.

With a bang, large pieces of concrete on the ground shattered and fell downward.

At this time, the fortress of Saint-Lee, from the second floor to the fourth floor above ground, was already an empty shell, and the height of the fifth floor was reduced by at least three meters, which was fatal to the building.

The concrete layer under Su Xiao's feet cracked in large areas, and he jumped towards the relatively intact foothold, and in an instant, most of the surrounding floor slabs collapsed.

After the ground stopped shaking, there was only a two-meter-wide foothold left in the office, and Su Xiao and Buck were standing on it, meeting each other on a narrow road.

The orange-red light was reflected from below, Su Xiao looked down, and below was a suspension dozens of meters high, supported only by a large twisted snail steel frame, and at the bottom was a piece of magma, which was produced by the smelting of metals and rocks.

A thick cloud of gray smoke floated above the magma, a toxic gas from explosives in the second basement level, and the oxygen below was extremely thin due to the explosion of Apollo.

With a bang, the foothold under Su Xiao's feet fell quickly and fell into the semi-liquid magma below.

The rolling heat wave came from below, Su Xiao rushed forward quickly, he didn't dare to exert much force under his feet, and it would be very troublesome to lose his foothold.

Buck seemed to know that, too, and his pace slowed down.

Sparks splashed, long knives slashed through the air, and the fight continued.

Outside the back of the fortress, a man wearing goggles and a leather suit clings to the wall.

"Do these two guys have a problem with their brains, and they continue to fight."

The leather-clad man witnessed the battle on the fifth floor through the window, a contractor of the Apocalypse Paradise, who appeared on the battlefield to pick up a bargain.

At first, the leather-clad man wanted to wait for Su Xiao and Buck to lose both sides, but after witnessing the almost ferocious battle between Su Xiao and Buck, he had no idea and was ready to retreat.

"Hey, I'm going to have to fight these crazy people after that, and my life is hopeless."

The leather-clad man let go of the noose and quickly slid underneath the fortress.

Inside the fortress, on the foothold where there was only one meter wide, Su Xiao picked off Barker's shoulder with a knife, and smashed the handle of the knife in his hand into the axe.

Bang!

Su Xiao took a few steps back, and after steadying his steps, he wiped the blood from his face.

Buck glanced at Su Xiao, thought for a moment, and then took a deep breath.

Bang.

The foothold at Buck's feet shattered, and he fell toward the lava below.

The boundary break line popped out of Su Xiao's cuffs and nailed into the ground beneath his feet, and he also jumped off the foothold.

Multiply~

The reel rotated rapidly, and at the same time as Su Xiao fell, a knife slashed out, and the knife slashed at Buck on the way down.

Buck was in mid-air, and he couldn't cut through the axe, so he could only hold two short axes in front of him.

Just as Buck was about to fall into the lava, he bulged a muscle in his right arm and threw the axe out of his hand.

A piercing whistling sound hit him head-on, Su Xiao's body turned sideways, and the short axe that was spinning at high speed flew by.

Just as the short axe was about to sink into the wall, it actually drew an arc and slashed at it again. This is Buck's ability: Whirling Chopping Axe (Lv.21).

With a loud bang, the short axe did not hit Su Xiao, but the handle of the axe hit the boundary break line.

The boundary break line was hit, and Su Xiao in mid-air swung to the side, and before he deviated from the trajectory, the five blades broke away from the blade of the dragon slashing flash and slashed towards Buck's right body, at this time Buck did not have a short axe in his right hand.

Blood splattered, and although Buck slashed three blades, two of them still hit him, one disemboweling, and the other nearly slicing his thighs apart.

Just as Buck was about to fall into the lava, he grabbed the snail steel frame beside him, which had been scorched red by the magma.

The green smoke rose, Buck's body swung out, and finally jumped into a half-collapsed underground passage, Buck's combat IQ was extremely high, and he was not afraid of life and death when fighting, but he always remembered that his purpose was not to fight to the death with Su Xiao, but to block Su Xiao.

Judging from the injuries of both sides, Buck lost, but in terms of purpose, Buck won.

Su Xiao's fingers pulled the reel, and his body stopped in mid-air, and five meters away from him was dark red magma.

"Buck."

Su Xiao didn't continue to chase, entering the narrow underground passage, Buck with a short axe in hand had a natural advantage, the previous battle between the two was five or five, whoever showed the flaw first would die, and after entering the narrow underground passage, Buck's victory rate accounted for seventy.

The boundary line was tightened, and Su Xiao was pulled to the foothold of the fifth floor, he looked around, and soon found the secret passage that the god had made Du Bo Yisi escape.

Jumping into the secret passage, there is an upward metal ladder, and the whole passage is already a little twisted.

Su Xiao climbed the metal ladder and barely squeezed through the protruding concrete cracks before he came to the top of the fortress.

There is a short asphalt runway above the fortress, with burnt marks left by rubber tires, this is a one-way airstrip, the risk of taking off here is not low, landing is basically impossible, the world has not developed a helicopter.

As soon as Su Xiao was about to leave, he saw a string of notches on the asphalt ground, which was the text of the Geya Alliance, which means: has been taken under the plane.

Su Xiao took out the tracker, there was a green dot on the tracker, which represented the vital signs of the little assistant, and the little assistant didn't know what method he used, but he was not frozen to death by the low-temperature air flow at high altitude.

With the resourcefulness of her little assistant, if she could take down Dupo Is, she would never take the risk of riding under the plane.

Although Su Xiao didn't see Du Bo Yisi himself, the clues were already obvious, and he only needed to trace the location of the little assistant.

Just as Su Xiao was about to leave the top of the fortress, he felt that the fortress under his feet began to tilt, and the almost hollow fortress could not hold it, even if the exterior was a rebar structure, but after losing the internal concrete support, the snail steel layer could not bear it.

Quack Quack ......

The harsh grinding of metal began to harsh, and the gunfire on the battlefield below the fortress was much more sparse, and most of the soldiers were watching the slowly falling fortress of Saint-Limmen.

The soldiers of the Geya Alliance were excited, and the soldiers of the Sun Kingdom were desperate, and under the gaze of both sides, the fortress of St. Limon collapsed!

After the deafening loud bang, smoke and dust rose into the sky, enveloping most of the battlefield in smoke and dust.

Inside the concrete trenches of the Kingdom of the Sun.

Rumble!

A light blue ball smashed into the trench, and the soldiers with guns around them were stunned for a moment.

Bang, bang, bang......

Several gunshots rang out one after another, all the nearby soldiers fell to the ground, the counterattack shield dispersed, and Su Xiao jumped out of the trench and rushed towards the territory of the Sun Kingdom.
