Chapter 573 Tianxiong City in Crisis
Just as Kogas was thoroughly humiliating South Korea.
In Antarctica, the situation in the Tianxiong underground city is also deteriorating rapidly.
More and more earth-burrowing dragons are traversing wormholes to reach Earth, digging towards Tianxiong City from all directions.
The number of densely packed red dots on the seismic wave monitoring system is countless, easily exceeding one hundred!
The underground unmanned military factory in Tianxiong City is operating at full capacity.
The robotic production line works tirelessly to produce cubic nitrogen explosives and C4, which are then transported by combat robots to various locations on the outer wall for pre-embedding.
A burrowing dragon gnawed through the wall, an explosion occurred, the tunnel collapsed, and the dragon's corpse blocked the way.
If it's just a burrowing dragon, Tianxiong City can still withstand it.
But the demon race isn't just composed of burrowing dragons.
It is unclear when it started, but the AI monitoring system has been popping up new alerts, indicating that unauthorized biological activity signals have been detected in multiple areas of the city.
Among them were quite a few fifth- and sixth-order demons!
These demons didn't take the route of the earth-burrowing dragon; instead, they entered through the main tunnel, ventilation duct, and drainage pipe that the earth-burrowing dragon had dug, connecting Tianxiong City to the surface.
They sneak into the city like rats, finding every no crack in the path.
The alloy grid of the ventilation duct has a hardness of HRC60, making it no different from tin foil in front of the claws of a fifth-order demon.
With a few tugs, the entire grid was twisted into a pretzel and thrown aside. The dark figure flipped over and jumped down from the pipe opening, landing inside the city.
Even more deadly are the sixth-order demons.
Once these things enter the city, combat robots simply cannot stop them.
The robot rushed forward and was smashed into parts with a single punch.
Only when several fifth-tier robots joined forces to block them could they barely manage to fight a sixth-tier demon to a standstill.
There are only so many Tier 5 robots in total.
The defensive forces of Tianxiong City are stretched thin, and the city is surrounded by enemies.
.....
The underground vault serves as a temporary command center.
The sound of keyboard typing was so dense it was like a hailstorm.
A dozen military laptops were lined up in a row, each screen displaying dense streams of data and rapidly switching monitoring feeds.
The technicians' fingers barely stopped, their eyes glued to the screen, their pupils reflecting a flurry of firelight and barrage-like alarms.
"A fifth-tier high-risk demonic invasion has been detected in pipeline G3 section 17. Four fourth-tier robots have been dispatched to intercept it."
"Interception failed. Target has breached the blockade and is moving towards Sector D!"
"Move the fifth-tier robots! Numbers five, seven, and ten are the closest; send them over!"
"Number 5 is currently dealing with another Tier 5 attack in section B2 and can't get away!"
"Then numbers seven and ten, go! Hold them off until number five is free, then we'll surround them!"
The staff officers were practically hoarse from shouting out one combat order after another, directing the already stretched combat robots to block and patch up the situation.
The burrowing dragon is actually the least troublesome one.
Once the sensor detects the vibration, the robot pre-buries explosives at the corresponding location. When the dragon head emerges, it detonates the explosives to seal the area.
One fire, one explosion – simple, brutal, and effective.
What's truly maddening are the elite demons who infiltrate through various channels.
Especially the sixth-order ones, they're too fast.
What does 200 meters per second mean?
In the blink of an eye, it has already darted from one end of the corridor to the other.
A single punch weighs over sixteen tons; an alloy door panel will deform upon being hit once, and be rendered unusable after two hits.
The AI system marks their movement trajectories, which appear on the map as wildly darting red lines, making it impossible to predict where they will appear next.
The fourth-order robots sent to intercept were all instantly destroyed.
Only when two or three fifth-tier robots work together can they barely hold their own against a sixth-tier demon.
But Tianxiong City only has about thirty Tier 5 robots left. They can only take care of one thing at a time, and they're constantly patching things up, and before they know it, the walls are almost gone.
"Another gap!"
"The ventilation duct in section H5 has been torn open, and two fifth-tier demons have entered the third level!"
"Send robots to intercept them!"
"There aren't any more! The nearest one is six kilometers away!"
The adjutant slammed his fist on the table, gritting his teeth and letting out a low growl.
Lin Shigong stood in front of the largest screen, without saying a word.
His face flickered between light and shadow on the monitor screen, making his expression indistinct.
But the fist clenched behind his back trembled with force.
"Report!!"
An informant suddenly stood up from his seat.
"Demons are charging at the entrance to Tunnel No. 2!!"
All eyes turned to them instantly.
The tunnel gate is the two-meter-thick explosion-proof gate at the entrance of the first-level main road.
Outside the gate is the main tunnel leading to the surface of the World Tree.
On both sides of the main tunnel, there are branch passages dug out by the drilling dragon.
"The surveillance cameras outside the main gate have been destroyed!" The informant quickly switched the feed.
"Only the internal monitoring system is still working!"
The moment the image appeared, everyone's heart sank.
That two-meter-thick explosion-proof gate.
Every second, it suddenly bulges inward a little.
"Thump!"
The entire door panel trembled violently, and concrete debris fell from around the door frame.
"Thump!!"
The bulge is larger than before, and the center of the door panel is visibly bulging out.
It's obvious without even guessing that a high-ranking demon entered the main tunnel through a side passage dug by the earth-burrowing dragon, bypassing all the surface blockades and directly reaching the entrance of the underground city.
Judging by the force of the impact, it's at least a sixth-tier, or even a seventh-tier!
And that door, under such force, wouldn't last long.
"Plant a bomb inside the door!" Lin Shigong gave the order immediately.
"Have the robots move the cubic meters of nitrogen explosive over there!"
The informant's expression changed as soon as he finished speaking.
He quickly checked the inventory data, his voice a little tense.
"Report! C4 and cubic nitrogen explosives..."
"It's all used up."
The command center was silent for a second.
"What?" Lin Shigong turned his head.
"We've used it all!" The informant's voice trembled.
"The inventory is depleted. The batch produced in the underground factory is still on the assembly line, and it will take at least half an hour for a new batch of finished products to come out!"
Lin Shigong was taken aback, then gave a wry smile.
Previously, the main force of Tianxiong City led most of its ammunition and equipment out of the city to intercept the demon army, but was wiped out by Kog'Gath on the surface, along with all its personnel and equipment.
Later, most of the remaining missiles and explosives in the city were mobilized to wear down Kog'Maw under the World Tree.
Although the effect was roughly equivalent to a tickle, the ammunition was indeed burned.
In the following hours, hundreds of burrowing dragons took turns attacking the city, and each one required a large amount of explosives to block.
Finally, there's the sealing off of various pipelines and the encirclement after the elite demons infiltrated...
It's like a person's blood is constantly flowing, but the rate of blood inflow can't keep up with the rate of blood loss.
It's only a matter of time before it runs dry.
I just didn't expect it to happen so quickly.
