Chapter 821 Digging Tunnels? We're Professionals!

That evening, the group stayed in Tianxiong City for a simple meal and then visited the newly built residential area, education center, and city defense system.

The next morning, Lin Shigong wanted to take everyone to visit the energy center, but Lin Mo politely declined.

"Lord Lin, please come again next time. We have already taken up quite a bit of your time."

"How can this be called a delay?" Lin Shigong persisted, saying:

"We've prepared lunch for you. Why don't you eat before you leave?"

Upon hearing this, Lin Mo didn't reply and headed straight for the teleportation hall.

He had already realized that if they stayed any longer, they would probably have to prepare dinner.

After their identities were verified, the group passed through the intercity teleportation portal and quickly returned to the Tian Shu underground city in the Arctic.

Today, all thirty-six underground cities of the Great Xia Dynasty have dedicated teleportation portals leading to the capital city of Tian Shu.

In the event of a disaster, war, or major medical emergency, personnel and emergency supplies can be transferred through Tian Shu and reach other underground cities in a very short time.

However, each use of the portal consumes energy crystals, and the portal's capacity is limited, so it is not open to ordinary residents to avoid congestion.

Under normal circumstances, people still mainly rely on rail transit for intercity travel.

As soon as Lin Mo stepped out of the teleportation area, Zhao Gang suddenly stopped.

"Commander Lin, let's go this way."

"Brother Zhao, is there anywhere else you'd like to go?"

Zhao Gang looked at the thirty-six teleportation portals in the hall and laughed:

"I was in charge of Project Ark before, but I stepped down later, so I don't know the specifics."

"It's like raising children; I want to see what they'll look like when they grow up."

Upon hearing this, Lin Mo was also somewhat tempted.

He frequently traveled between Tian Shu and Terra, and had read many reports on other dungeons, but had actually visited very few of them.

"Alright, let's go take a look."

After saying that, he started walking towards the teleportation portal.

"We won't go this way," Zhao Gang shook his head.

"Take the subway."

Lin Mo was taken aback.

Kyle was also somewhat puzzled.

"Since there's a portal, why choose a slower mode of transportation?"

"Going through the portal will only allow you to see the departure hall and the arrival hall," Zhao Gang said with a smile.

"We're not on an official inspection today, and we're not in a rush. We're just visiting, so of course we want to see how people usually get around."

Thorin immediately became interested.

"I want to take the subway too!"

In the past, when he came to Tian Shu City, it was either for diplomatic activities or military negotiations. He had never actually experienced the public transportation that ordinary people used.

Moreover, he had seen it on his phone; it was a huge, long thing, like a burrowing dragon.

Fendona and Grom were equally unwilling to miss out.

........

Apart from the cities of Tianyong and Tianxiong in Antarctica, all 34 underground cities in the Arctic have been connected to the polar high-speed magnetic levitation vacuum rail network.

The entire track consists of an underground loop and more than ten radial lines, with a maximum operating speed of over 1,000 kilometers per hour, meaning it arrives almost instantly after accelerating.

But ordinary people still habitually call it the subway.

As the group arrived at the transfer hall, a train bound for Tiankui City was about to pull into the station.

Grom the centaur's massive body drew the attention of many onlookers as he passed through the turnstile.

"This door is nice; it's wider than many of your room doors."

Grom nodded in satisfaction.

Sorin, however, kept staring at the tracks behind the transparent barrier, muttering to himself as he looked at the information on his phone:

"A fully enclosed vacuum tube, a magnetic levitation vehicle, and an independent braking system in emergency situations..."

The more he looked, the more envious he became.

"If this kind of track were laid in Terra..."

Lin Mo reminded him:

"Its cost is very high, but we are building it because the underground city is relatively dense, making it cost-effective."

"Terra is too big, the cities and races are scattered, and it is easy to be attacked by monsters or even demons along the way, and the maintenance cost is also high."

"However, underground routes can be avoided, but that would require digging tunnels, which wouldn't be cheap."

Thorin's eyes immediately lit up even more.

"Digging tunnels?? We're professionals at that!"

Lin Mo was taken aback, then burst into laughter.

Yes, dwarves are not only good at blacksmithing, but also at digging tunnels.

Their individual strength, coupled with specialized magical excavation equipment, may not be weaker than the tunnel boring machines of the Great Xia Dynasty.

However, he thought of a problem and said:

"Terra has portals, right? This is definitely not as convenient as that."

Thorin shook his head, glanced at Kyle, and said sarcastically:

"In your Great Xia language, it means you can't put all your eggs in one basket."

"Moreover, railway construction takes time, but teleportation portals are unnecessary; they could arrive at any time, which won't do."

Kyle remained indifferent, already used to it.

Before the demons arrived, the various races fought each other from beginning to end, so it's normal to be on guard.

After listening, Fendona and Grom nodded thoughtfully.

After returning home, their clans will most likely seek out the Great Xia again to discuss a new round of technological cooperation.

At that moment, the silver-gray train silently pulled up beside the platform, and the doors and the isolation doors opened simultaneously.

The group entered the accessible carriage. Grom stopped in the specially reserved spacious area, while Fendona curiously looked out the window at the platform.

After the train started moving, she felt almost no noticeable vibration.

"So stable."

"It's certainly stable when leaving the station at low speed."

Lin Mo pointed to the speed display above the carriage.

The number quickly climbed from two hundred to eight hundred, eventually stopping at 1,020 kilometers per hour.

Fendona instinctively gripped the seat armrest.

"So fast?"

"Underground railways are free from storms, tsunamis, and surface obstacles. As long as the tunnel structure is stable, they are actually safer than surface transportation."

As the two were talking, a young student across from them finally mustered up the courage to raise his phone and walk over.

"Uncle, may I take a picture with you?"

"Can."

Lin Mo smiled and agreed.

However, this sentence was like flipping a switch.

Passengers in the nearby half-carriage who had been watching couldn't resist any longer and took out their phones to approach.

Lin Mo's smile froze instantly.

Fendona suppressed a laugh and whispered a reminder:

"It's no use hiding behind Grom now; they can still see you."

"I should have borrowed Kyle's magic cloak."

Wu Suowei has already stepped forward.

"Please don't rush, you can take photos together, but please group according to your seating area and do not block the doors."
