Chapter 443: Chapter 217: Upgrade Location Chapter 443: Chapter 217: Upgrade Location Yan Fei first used an unexpected method to enter the underground gold vault, then threw smoke grenades to release smoke and disrupt the surveillance cameras within the vault. He swiftly entered the vault, gathered all the gold inside and stored it in the Universal Space, and then quickly evacuated the underground gold vault. On his way out, Yan Fei even had time to pick up all the smoke grenade casings from the floor, leaving no trace behind.

After retreating to the exterior abandoned mine tunnel, Yan Fei stood at the entrance to the underground gold vault and retrieved the massive rebar concrete component from the Universal Space, placing it back in its original spot. In order to ensure that the rebar concrete component was perfectly returned to its original position, Yan Fei constantly adjusted its angle. He would take the rebar concrete component out of the Universal Space, then store it back, and take it out again. After adjusting the position several times, he finally returned the rebar concrete component to where it had been. Unless one examined the cement adhesion between the components carefully, no one would imagine that this hundred-ton object had been moved.

Because the cement adhesion was missing, it was much easier for Yan Fei to move the rebar concrete component back and forth. A few position adjustments later, aside from consuming a bit more spiritual power, the process did not place much of a burden on his physical body.

Yan Fei carefully cleaned up the traces of his entry into the underground gold vault, not anticipating that a rat from the outside mine had slipped into the vault with him. Then, this rat was accidentally stepped on and killed by the entering guard personnel, and it was because of this rat that the investigators from The United States of America found a slight direction in their case investigation.

However, all of this had nothing to do with Yan Fei anymore. After returning to the outside mine tunnel, he began a rapid retreat. During his retreat, he also took the dirt and rocks he had previously stored in the Universal Space and placed them back in their original positions. With this action, Yan Fei had essentially restored everything in the abandoned mine tunnel back to a state hardly different from its original one.

Then, Yan Fei returned to the underground waterway below. He dove into the water again and retraced his route along the waterway. This was Yan Fei's second time passing through this underground waterway; having already learned the length of the waterway from his first passage, he had a clear idea of the distance this time around and could plan his swimming speed accordingly. When he surfaced on the other side of the underground waterway, he showed no signs of distress, which was a stark contrast to his struggle during his first crossing.

Back on this side of the underground waterway, Yan Fei finally took a breath of relief and had time to check the latest status of his Drone. After retrieving the gold from the underground gold vault using Universal Space, some changes had appeared in the Drone Data's red question mark status. There, the upgrade condition of 1000 tons of gold had been met. This meant that the Drone Upgrade only had two unmet conditions left: 10,000 tons of Special Alloy and 10,000 tons of Bio-materials.

For Yan Fei, completing these two Drone Upgrade conditions would be a piece of cake, especially since he had already fulfilled the most important and most difficult of the upgrade conditions, it was like having the bitter first and sweet later. As long as he methodically prepared, he would be able to collect the 20,000 tons of Upgrade Materials needed for the next Drone Upgrade.

On this sortie, Yan Fei not only scanned the B-2 Upgrade Template but also obtained the 1000 tons of gold needed for the Drone Upgrade. Judging from the amount of gold he had collected, there would be plenty left over after the Drone Upgrade, and all of this put him in a very good mood.

With his mind at ease, Yan Fei continued to swiftly retrace his way along the path he had come from, making sure to restore any obstacles he encountered along the way to their original state. When he returned to the Subway Station outside and left, he discovered that there were no signs of any abnormal situation inside the station. It seemed that his previous misdirection had successfully misled the New York Federal Reserve Bank's line of thought; they had not realized that Yan Fei had entered the underground gold vault through the New York Underground Pipeline Network, so they had not yet conducted a thorough search at the Subway Station exits.

Without any enemy snipers or blockades, Yan Fei easily left the New York City Area and returned to the beach outside. He summoned the submerged Drone, then dived into the Drone Cockpit. Yan Fei took one more look at New York City behind him, had the Drone descend, and began to navigate stealthily through the ocean, quickly moving away from New York. Once far from the Coastline, the Drone resurfaced and sped southward across the sea at three times the speed of sound. By this time, it was only 10 PM in New York.

Yan Fei started to retrace his route back to New York, but when he arrived in the territorial waters of the Caribbean Sea of Central America, local time in New York reached midnight, and the Drone Data began a comprehensive refresh. In an instant, the Drone Data was renewed, restored to optimum condition. Then, the Drone continued through the Panama Canal, using the same approach as before by adhering to the bottom of large cargo ships to enter the canal. However, now in the late night hours, once the Drone entered the canal, it left the cargo ship and sped to the canal exit at its highest speed. Using an Oil Tanker for cover at the exit, Yan Fei finally reached the Pacific Ocean outside. This way, he saved two hours of time compared to his inbound journey.
