Chapter 441: Chapter 216 The Golden Heist_2 Chapter 441: Chapter 216 The Golden Heist_2 Half an hour later, Yan Fei had finally dug forward 10 meters. According to the display on the 3D map, just beyond the left stone wall was a corner of the Underground Gold Vault's wall. It was now 7 PM in New York local time, and since Yan Fei had entered the Subway Tunnel, he had been working non-stop underground for two hours. Even with his formidable strength, he was beginning to feel some fatigue.

Yan Fei took out the black sphere from the Universal Space and used the Mysterious Energy within it to recover from the tiredness. He rested on the spot for a while, then proceeded to dig towards the direction of the Underground Gold Vault's wall. Ten minutes later, Yan Fei had dug through the softer rock layer near the vault and encountered the hardest rock layer within. The 3D map showed that this hard rock layer was five meters thick, and beyond it was the Underground Gold Vault's massive reinforced concrete structure.

Being extremely close to the Underground Gold Vault, it was certain that various anti-theft measures were installed inside, including safeguards against anyone attempting to enter the vault by tunneling from underground. Therefore, if Yan Fei tried to get through this rock layer with explosives as he had done before, he would definitely be detected by the Underground Gold Vault, leading to failure. In order to pass through the thick rock layer without making a sound, Yan Fei had no choice but to adopt the most primitive method–drilling.

Yan Fei sized up the rock layer and decided on the direction to proceed, then he took out a huge steel chisel from the Universal Space. He inserted it into a fissure on the rock wall and began to pry the rocks. This steel chisel was of excellent quality; he had purchased it from a tool shop in New York for use at a Critical Moment. His current strength was monstrous, and with only a light effort to pry, he chipped off a piece of rock, which he then promptly stored in the Universal Space, without making any noise.

Soon, all the rocks with fissures had been pried off by Yan Fei, leaving a smooth and even rock layer with no place to leverage from. However, Yan Fei was not frustrated–he positioned the steel chisel on the rock, grasped it with one hand and lightly tapped the top of it with the other. With one strike of his full body strength, the chisel silently penetrated into the rock. Then, using both hands, Yan Fei pried off even larger chunks of rock.

Yan Fei's method resembled the Chinese Stonemason technique of hammering a steel chisel to extract stone. However, a stonemason uses a hammer, which creates a loud noise when it strikes the chisel. Yan Fei's movements fully employed the techniques of an Innate Expert. A light tap was equivalent to the full force of a human body. The chisel punched into the rock wall without making noise, perfectly suited to Yan Fei's current situation.

In this manner, Yan Fei slowly excavated the hard rock layer, relying on his extraordinary physical strength. Even so, Yan Fei had to rest several times, continually replenishing the energy spent by eating. Due to excessive use, the steel chisel eventually broke. Fortunately, Yan Fei had prepared several spare ones in the Universal Space, preventing the embarrassment of having no tools to use.

Two hours later, when Yan Fei removed the last piece of rock in front of him, he finally uncovered the gray reinforced concrete component inside. This indicated that after his arduous digging, he had finally come close to the Underground Gold Vault. The reinforced concrete component behind was the vault itself. However, Yan Fei's position was not at the vault's entrance but at the innermost part of the Underground Gold Vault.

During the initial construction of the vault, the builders had thoroughly examined the arrangement of the nearby Underground Pipeline Network and blocked all potential entrances. Still unconvinced, they added massive reinforced concrete structures as the vault's walls. With these defenses, including the depth of 25 meters underground, the obstruction of all surrounding entrances, the layer of hard rock outside, and the hindrance of the massive reinforced concrete components weighing a hundred tons, they ensured the Underground Gold Vault could never be breached from other locations. The only way to enter the vault was through the door.

Among all the anti-theft measures, these massive reinforced concrete structures were a crucial link. Weighing over 100 tons each, they were impossible for an individual to move. Even using explosives, one couldn't blast through these hard components, and the loud noise generated would be promptly noticed. It was because of these seemingly insurmountable defenses that it was possible to store so much gold inside with confidence.

The Underground Gold Vault was tightly secured, arguably the world's most impregnable fortress. Apart from Yan Fei, no one could quietly infiltrate it. But Yan Fei, with his immense strength and possession of the mystical Universal Space, could break into this place. Even when faced with such a huge reinforced concrete component, which was immovable to the average person, he could easily handle it using the Universal Space.

Although Yan Fei was confident in entering the Underground Gold Vault, it was not so easy to collect the reinforced concrete component. It was cemented together with other giant reinforced concrete structures, so Yan Fei could not pick it up separately. He had to concentrate his Spiritual Power, constantly activating the Universal Space, trying to absorb the reinforced concrete component into it.
