Super Invincible Battleship
Chapter 1003

Chapter 1003: 403 Chapter 1003: 403 Unlike many other cities in China, Beijing has a long history that spans thousands of years. For the past few centuries, it has been the political center of China and the focus of its people nationwide. Because of its rich history, the underground situation in Beijing is extremely complex, filled with secret tunnels and subterranean structures everywhere.

However, these subways and buildings exist independently of each other and are not interconnected. Apart from a small portion that has been discovered and utilized, many more such projects remain unknown, still hidden beneath the city.

In recent years, to construct subways and other major projects, China has enhanced its exploration of Beijing's underground. Yet, even with all of China's efforts, they could not fully grasp the vast underground landscape of Beijing. But this was no problem at all for the Drone Quantum Radar. With the power of the Quantum Radar cranked up to the maximum, the entire underground area of Beijing down to 100 meters was under its surveillance.

To fulfill his purpose of an underground assault, Yan Fei not only scanned the underground terrain of Beijing from the air but also switched his drone into stealth mode to infiltrate the city's depths, gaining a clear understanding of everything below. To avoid detection of the drone's subterranean entry, it always entered from the canal bed far from Beijing and then traveled towards the city at a depth of 200 meters, ensuring that no trace of its movement was revealed.

After several days, with dual-mode underground traversal and Quantum Radar scanning, Yan Fei gained a mastery of the underground situation in Beijing at a depth of 400 meters. He knew the locations of all the underground rivers, tunnels, passages, ancient tombs, and hidden chambers so well that no one else in the world could possibly be more knowledgeable about the underground situation in Beijing.

Based on the findings of the drone's underground exploration, Yan Fei carved out an underground passage for himself. He planned to use this secret route to penetrate the Yang Family's villa compound and assassinate Yang Liu without anyone noticing.

This underground tunnel was extremely secretive and was sure to remain undetected. However, it was not fully connected; there were some broken segments along the way, and he sometimes had to navigate through several underground waterways to continue. Where a connection was not possible, Yan Fei would use tools to break through, allowing him to reach the grounds beneath the Yang Family's villa complex.

Finally, Yan Fei would enter a narrow tunnel at a depth of 300 meters and reach an underground thermal spring, then swim through the underground spring to the surface thermal bath. This bath was a key location in the Yang Family's villa complex, where the family members relaxed in the hot springs. Recently, under the stress of having lost his son, Yang Liu was exhausted. To alleviate the pressure, Yang Liu soaked in the bath at around ten o'clock every night for twenty minutes.

Ordinarily, even at home, the death-fearing Yang Liu was always surrounded by many bodyguards. But it was only in this bath that his bodyguards did not enter; instead, they waited outside. At this time, Yang Liu would be alone inside, making it the perfect opportunity for Yan Fei to strike.

To protect his privacy, this bath was one of the few places in the Yang Family's villa complex that did not have surveillance cameras installed. So even if Yan Fei appeared and killed Yang Liu, no one would know who the assassin was. Nevertheless, Yang Liu was very vigilant; if he noticed anything amiss, a single shout, and his bodyguards would burst through the doors.

These bodyguards might not be able to stop Yan Fei from killing Yang Liu, but they could potentially record the process of Yan Fei's assassination, which would be extremely detrimental to him. Therefore, Yan Fei had to act quickly and land a decisive blow before Yang Liu could react, and then escape swiftly.

Actually, Yang Liu's bodyguards had previously considered the security flaw presented by the bath. But after learning about the underground hot spring, they dismissed the concern. According to their information, the hot spring originated from fissures in the rocks 500 meters underground, surrounded by hard rock, which made it impossible for anyone to enter the spring from the outside.

Furthermore, the springs emerging from such depths were extremely hot; at 500 meters underground, the temperature reached 100 degrees Celsius. However, as the spring water rose, the temperature gradually decreased to around 40 degrees Celsius at the surface, perfect for human bathing. Given the high temperatures, the bodyguards were convinced no one could safely emerge from the underground.

Therefore, except for the entrance to the bath, the bodyguards believed there were no other channels for anyone to get inside. They were confident that by guarding the bath's entry point, they could ensure Yang Liu's safety.

The bodyguards had only rudimentary data on the spring and lacked advanced exploratory tools like the Drone Quantum Radar, so they were unaware of a lateral crack in the spring 300 meters below the surface, just two meters away from an underground passage. By entering that underground passage and breaking through the two-meter-thick hard rock layer, one could enter the underground thermal spring via that lateral tunnel.
