105: Chapter 105 The Southern Fortress Engine Stopped! Icethorn Approached the City from Seven Kilometers Away

The chain reaction following the engine's speed drop erupted completely within three minutes.

The speed of the southern lv.3 fortress dropped from twelve to eight, and from eight to five.

It was the same way of dying as Iron Spine's fortress in the north.

The exhaust pipes were blocked, backpressure soared, and power output continued to decay.

Zhao Tiezhu seized this window of opportunity.

The iron wall approached at a full speed of fifteen km/h.

The distance shortened from one kilometer to five hundred meters.

At a distance of five hundred meters, the penetration rate of the 105mm cannon soared to over fifteen percent.

The ten cannons of the iron wall fired in unison.

Bang! Bang! Bang! Bang! Bang! Bang! Bang! Bang! Bang! Bang!

Ten shots fired in unison; two penetrated the front wall of the southern lv.3 fortress, one pierced the outer layer and got stuck in the ribs, and one directly pierced through the second layer.

"Battalion Commander Zhao! One shot pierced through two layers!"

"I saw it!" Zhao Tiezhu laughed out loud.

"Can't pierce your lv.3 at five hundred meters? Show him!"

The southern lv.3 fortress's counterattack came.

The ten cannons that were still functioning fired simultaneously.

Bang! Bang! Bang! Bang! Bang!

The front wall of the iron wall was pierced by two shots.

"Battalion Commander Zhao!"

"It's fine! The ribs can hold! My wall is newer than his! The welding process is better than his!"

Zhao Tiezhu's words revealed a rugged, head-on confidence.

Lv.3 versus lv.3, a head-on bombardment; they began to penetrate each other at a distance of five hundred meters.

But the iron wall's wall was newer, better maintained, and had a stronger ability to take a beating.

The wall of the southern lv.3 had already been bombarded dozens of times from the front, and with Lu Chen's continuous dismantling from the side and rear, its overall condition was deteriorating rapidly.

Lu Chen did not give the opponent a chance to catch their breath.

The Polaris cut toward the left side again from the rear.

The tenth round of fragmentation grenade was loaded.

[Consumed 50 Truth Points. fragmentation grenade: 12 pre-loaded for the tenth round. Current balance: 3040 points.]

Twelve fragmentation grenades washed over the gun positions on the left wall.

Bang! Bang! Bang! Bang! Bang!

The rotation mechanisms of another two cannons were jammed by shrapnel.

The effective firepower of the southern lv.3 dropped from ten cannons to eight.

The iron wall had ten cannons facing eight from the front; the firepower advantage was growing larger and larger.

He found a weak point on the left side.

It was not a repaired weld.

It was structural damage caused by the frontal bombardment.

In the area where the front of the wall was hit continuously by the iron wall, the vibrations were conducted along the structure of the armor plates to the side.

Stress cracks appeared on the weld line of the side wall.

This city lord saw the heat source anomaly of that crack through the precise detection of the radar.

The heat conduction efficiency at the crack was three times higher than the surrounding area, appearing as a bright line on the radar.

"Battalion Commander Zhao, concentrate your cannons on the front-left position."

"Front-left? Why?"

"The impact vibrations from the front-left will be conducted along the structure to the weld line on his left wall."

This city lord tapped his finger on the joystick.

"I found a crack on the left side. You help me shake it open, and I will blow it up with the Harpoon Cannon."

"Understood!"

The iron wall's firepower began to concentrate on the front-left area of the southern lv.3.

All ten cannons locked onto that area.

Bang! Bang! Bang! Bang! Bang! Bang!

Three consecutive volleys.

Thirty shells were concentrated within a five-meter-wide area.

The vibrations were conducted along the internal structure of the armor plates to the left side.

Lu Chen saw the change through the radar.

That crack extended from twenty centimeters to eighty centimeters.

Enough.

Harpoon Cannon.

The crosshair locked onto the middle section of the crack.

One hundred and twenty meters.

Index finger pressed.

Bang!

The harpoon hit.

It embedded into the crack.

Delay fuse.

Boom!

The implosion completely tore the crack open.

An armor plate two meters wide and one and a half meters high fell off the wall, smashed onto the ice, and splashed up a cloud of crushed ice and rust.

A breach appeared.

"City Lord! Another hole has opened!"

"Again."

The Heavy Machine Gun aimed at the breach, and one hundred and fifty rounds were poured in.

The warheads bounced and shattered inside the wall.

Two steam pipes were severed.

White mist began to emerge from inside the left wall.

The iron wall's artillery continued to bombard the front.

His Heavy Machine Gun and fragmentation grenade continued to wash over the side.

Two-way pincer attack.

The fighting capacity of the southern lv.3 was collapsing at an extremely fast speed.

The engine only had thirty percent output left, and the speed dropped to two kilometers per hour.

The wall was pierced in eleven places from the front, and a two-meter-wide hole was opened on the side.

Effective firepower dropped to six cannons.

The iron wall approached to within three hundred meters.

At a distance of three hundred meters, the penetration rate of the 105mm cannon exceeded twenty-five percent.

The iron wall's ten cannons against six cannons; the firepower was overwhelming.

"Battalion Commander Zhao, it can't hold on much longer."

"I can see that!" Zhao Tiezhu's rough voice revealed excitement.

"The front wall is deforming! The load-bearing structure is collapsing!"

The front wall of the southern lv.3 began to show large-scale deformation under the continuous bombardment of the iron wall.

Six minutes later, a ten-meter-wide armor plate in the middle section of the front wall fell off entirely due to the accumulated damage from continuous hits.

A heavy sound rang out.

Steel fragments scattered on the ice.

The wall suffered structural damage that pierced through it.

The fortress's engine completely stalled at the same moment.

The exhaust pipes were completely blocked, and the backpressure caused the engine's pistons to get stuck in the cylinders.

The southern lv.3 stopped.

The one-hundred-and-ten-meter-long steel behemoth stood motionless on the ice.

The wall collapsed over a large area.

The sound of cannons stopped.

The six cannons that could still move fired one last volley at the iron wall at the final moment.

Two shots hit.

Two cracks appeared on the front wall of the iron wall.

The outer layer was penetrated, and three ribs of the second layer were broken.

"Battalion Commander Zhao!"

"I'm fine! The iron wall's wall can still hold! But the front can't take any more hits!"

Zhao Tiezhu's voice was mixed with heavy panting.

"Two shots pierced the second layer; if five more hit this spot, it will be pierced through."

"No need to take any more hits."

Lu Chen looked at the stationary light mass on the radar screen.

"It has stopped."

The Mechanical Arm ejected.

High-dimensional degradation initiated.

Blue light shone in the twilight.

"The iron wall is injured, you come to degrade it, I'll watch from the side." Zhao Tiezhu's voice returned to normal.

This city lord controlled the arms, sending the armor fragments scattered on the ice and the debris from the collapsed wall into the degradation one by one.

The blue light pulsated one cluster after another.

Three minutes.

[Cumulative degradation income: 2384 Truth Points. Current balance: 5424 points.]

Five thousand four hundred and twenty-four points.

Enough.

The top core of the Power Engine requires four thousand points; current balance is five thousand four hundred and twenty-four.

Now is not the time to spend points on technology.

"Chief of Staff Zhou, the front!"

"The Ice Thorn has advanced to seven kilometers!" Zhou Yuan's voice was strained to the limit, "The outer layer of The City-State's front wall has peeled off in large areas! The second layer has multiple penetrations! Horton is fighting back desperately but can't hold them off!"

Seven kilometers.

At a distance of seven kilometers, the penetration rate of the Ice Thorn's one hundred and eighty cannons has already exceeded fifteen percent.

"The iron wall and the Polaris must return to defend immediately!"

"Received!"

Lu Chen slammed the supercharger to the bottom.

The Polaris ejected forward.

"Battalion Commander Zhao, follow me!"

"The iron wall is following at full speed! The supercharger is still shaking! But it can still run!"
