A few hundred meters from the north entrance, a 5-ton MTV Driller was busy making some holes. Each hole was 10 cm in diameter, as deep as 20 meters, and would be use to insert sleeping gas's pipe into underground tunnel.

Next to the MTV Driller, Sergeant Lucy oversees the work. When Colonel Maddox and other officers approached her, she immediately handed over her tablet.

"Colonel, this is the sensing result from portable seismic detector. Based on activity inside it, the underground tunel splits into two branches down there."

After studying some pictures on the tablet, Colonel Maddox said, “The tunnel really split into two directions."

“Yes, Sir. The two branches continued to climb and each one of them seemed to be go to Levsait and Raisait."

A smile immediately bloomed in Major Callum lips. "Then, this is the most ideal location to cut the flow of opposing side’s combatant.”

Sergeant Lucy nodded and then firmly added, “Exactcly, Sir.”

“Sergeant, how many holes have been made by your crew?"

"So far, three holes. We drilled it as gentle as possible, exactly up to two meters before penetrating the underground tunnel's ceiling."

"We need more." Colonel Maddox paused for a moment before continuing, "Make it into a pattern so we can insert explosives and create a four-meters wide hole. Also, you don’t need to do it in silence this time."

"Do we cancel the use of sleeping gas, Sir?"

"Yes, we replace it with a plan to flood the tunnel with water, and followed by electricity."

"Understood, Sir."

Wasting no time, Sergeant Lucy led her crew carried out their new task. Meanwhile, Lieutenant Juan led his men prepared the explosives. As for Major Callum, he and his men prepared the water and electricity to be used.

Marine Industrial Area, Center of Levsait.

In one corner of Marine Industrial Area, stood a facility called Energy Storage Station Levi-01. This facility was used to store giga power bank, a device invented by Tesla USA in 2024.

As the name suggested, giga power bank was used to store electricity in massive scale. It had a size of a 40-feet container, could store electricity up to 800 MW, and initially would be used to support the power station to recharge electric cars. It was also durable, free of inflation, and friendly to environment.

However, when you compared it to other present energy sources, giga power bank was too expensive to support a large-scale manufacturing industries. Therefore, for now only TF Amethyst who interested in adopt it. As giga power bank was the easiest and fastest option that could be paired with any friendly to environment energy sources.

Tonight, eventhough Levsait was under tunnel attack, all activities in the center of Levsait were running as usual, including daily operations at ESS LEVI-01. Of course, in order to anticipate the worst scenario, Nate already deployed 2200 combatant to form final protection line and defend it at any cost. The defender also supported by attack hello and other heavy asset.

Therefore, Site Manager Russel could calmly started his past midnight shift. And as usual, once he entered his office, he immediately checked the daily report.

Every day, some quota of electricity generated by Wind Power Plant and Solar Power Plant in Levsait would be stored to giga power bank in ESS Levi-01. So far, of the 480 units of giga power banks operated by ESS LEVI-01, 297 units had been fully charged and ready to be used in winter, when Solar Power Plant couldn't generate electricity at its maximum output.

A smile immediately bloomed in Site Manager Russel's lips as he found that another three units giga power bank would be ready to be used. Then, with hasty steps Engineer Emerson suddenly entered the room.

As he handed over a piece of emergency request, Engineer Emerson said, "MCG asks us to provide electricity up to 700,000 kWh, through substation near the northern entrance."

As a black question mark appeared on his face, Site Manager Russel asked, “Why do they need such big electricity?”

"Dunno, they didn't say the details."

“What a strange request.”

"Yes, it is. But Chief Nate has just contacted us and requested that we had to fulfill MCG's request as a top priority."

In an instant, the question mark on Site Manager Russel's face thickened as he fell into contemplation. Electricity as big as 700,000 kWh was not trivial or cheap. In some countries on earth, it could be used to power a city with 60.000 population.

However, as Chief Nate already gave his consent, in the end Site Manager Russel could only comply with the request. “Use giga power banks at 6th floor.”

“Understood,” Wasting no time, Engineer Emerson carried out the order.

Throughout his long and dark carrier in an elite military unit, Captain Norrak already saw every single of horror that only could be found in the battlefield. Therefore, he was completely sure there would be no more horror that would make him flinched, let alone felt a terror that would shock his heart to its core.

However, battlefield was a place which full of sneaky surprise in nature. When an overconfident fellow thought he already saw it all, something new would popped up and kicked his balls from the direction he least expected.

In short, Captain's Norrak confidence instantly gone when Brigadier Zommat and three other captains, who were standing right in front of him, suddenly became meat paste after a head of giant iron carriage fell on them without prior warning.

At that time, Captain Norrak even scream histerically on reflex, as if he was an innocent virgin who for the first time in her life ecounter a butt gropping from a thug.

After that, the terror which shook Captain Norrak's heart to its deepest part, gave him an urge to exit the underground tunnel as fast as possible. Without delay, Captain Norrak climbed the side of the giant iron carriage and arrived on the surface through a tiny gap on the half-opened entry point. And somehow, his men followed his lead as fighting spirit and bloodlust filled their heart to the brim.

On the surface, Captain Norrak and his men was greeted by dozens giant iron carriages. Each one of them had a pair of bright light which looked at them like a starving devil. Then, as soon as his men draw their shortsword, the giant iron carriages immediately approached them in full speed. With ease, the giant iron carriages hit and crushed Captain Norak’s men mercilessly

Even to this moment, Captain Norrak could still hear the ‘Crunch crunch crunch!!’ sound as his men were run over by giant iron carriage's wheel. He also could clearly remembered the horror and despair in his men's eyes just before their body became meat paste.

And somehow, Captain Norrak who stood in place while trembling in fear, survived and ended up as prisonner of war. After that, two friendly people gave him a drink that made his head felt very light, but at the same time his memory became very vivid. And every time they asked him, Captain Norak would voluntarily answer them in detail.

"What drinks do you give me?" Captain Norrak weakly asked.

“Don’t worry, the med is not dangerous."

One of the friendly people calmly replied, and Captain Norrak lightly nodded.

“I see.”

The second friendly people then asked, "The detail about underground tunnel, have you said everything?"

"I have."

“About Prince Makar's location, are you sure his command post is in the third largest building in the Battle Group A's first camp?"

“Yes, I'm. I entered the building several times to receive a brief from Prince Makar directly."

“Thank you for your cooperation.”

“Your welcome.”

Captain Norrak casually answered, without realizing that he had just helped to process to eliminate tens of thousands of Battle Group A's personnel on the underground tunnel.

By using intel from IDG as the base, Colonel Maddox calculated the size of the underground tunnel, along with the amount of water needed to flood it. After an hour full of work hard, he finally got the final estimation. Wasting no time, he then gathered his men for the final check.

Colonel Maddox calmly opened the meeting, “Juan, let’s start from you.”

Wasting no time, Lieutenant Juan reported, “Explosive are already inserted, and ready to detonate at any second. I make the last confirmation myself.”

“Good,” Colonel Maddox then turned his gaze to Major Callum. “Callum, your turn.”

"We have adequate water and electricity," Major Callum calmly replied. “As soon as the hole to access the underground tunnel formed and Captain Murphy's company secure it, we will immediately throw the hoses into it.

In total, we use ten 8-inch hoses to flow the water from the nearest water reservoir. Once the water reaches the desired volume, we will immediately expose it to electricity."

Captain Murphy who was tasked with securing MCG's operation immediately added, "My men will secure and make sure there are no hostile coming out of the underground tunnel."

Colonel Maddox immediately nodded three times before asking, “Is there any question?"

Captain Murphy immediately raised his hand, and after Colonel Maddox nodded his head he immediately asked, “How do we know how much electricity is needed to eliminate every hostile at the underground tunnel?"

“We have our method. It’s a simple and effective method, but hard to explain how it work. So, please just believe in our judgment, Captain” replied Colonel Maddox.

“Understood, Sir.”

“Is there any other question?” Colonel Maddox waited for a moment before continuing, “No, then let’s start the party.”
