After Ye Fan issued an order to Origin, Origin soon understood it and arranged for a steel armor to walk over.

"Boom!" Two vacuum implosion bombs whose power was reduced by 99% were directly launched, and the instant powerful suction absorbed a large amount of yellow sand on the mound.

In less than three seconds, this mound of yellow sand condensed into a large pit more than ten meters wide, and Ye Fan was standing in the center of that pit.

At the bottom of the big pit, a complex structure made of stones appeared. There were various strange reliefs on the stones, which seemed to tell a story.

"Boom!" Three more vacuum implosion bombs were fired, which more than doubled the width of the crater again, and the things hidden under the sand dunes finally surfaced.

This place, like a large entrance, is surrounded by huge stones as the cornerstone, but an entrance can be clearly seen.

What a basement seems to be here.

At this time, the large steel armor also walked over according to Ye Fan\'s order, punched the boulder, and began to scan it in detail using the sonar mode.

Soon, the results of the scan were available.

Unsurprisingly, this place is really an entrance, and according to the sound waves returned by the sonar, it seems to be a hundred meters deep below it, which is a huge complex of buildings.

What surprised Ye Fan even more was that these huge stones that looked primitive and vicissitudes of life were actually not real stones, but a layer of stones covered by a special metal surface.

Ye Fan knows nothing about whether it is to cover people\'s eyes or the design of this building is like this.

Ye Fan took apart the ship-cutting knife in his hand, and threw it to the large steel armor, because on the narrow ground, this large combat weapon was simply not available.

Soon, two shoulder cannons appeared on Ye Fan\'s steel armor. This type of shoulder cannon was the plasma cannon that directly melted the gate of the laboratory when Ye Fan attacked the underground laboratory in Chicago last time.

Ye Fan signaled Tang Xue to step back. On the holographic projection, the sonar scanned the position of the entrance shown and quickly aimed at the two plasma guns.

"Boom! Boom!" Two generators shot out, instantly melting the boulder at the entrance into a huge hole.

Upon seeing the rest of the steel armor, they shot out the plasma cannons on their shoulders, melting away the entire boulder covering the entrance.

The huge stone at the entrance seems to be connected to a power mechanism somewhere, but the results of the sonar scan and return show that this power mechanism seems to have been damaged.

There was no way, Ye Fan made the last move.

Considering that the things hidden below are too concealed, Ye Fan didn\'t rush in. Instead, he let the other steel armors take the lead. He walked in the middle, while Tang Xue was behind him.

The entrance that appears after melting the boulder is a downward staircase. Because it is night below the surface, the visibility has infinitely approached zero.

Therefore, the searchlight on the chest of the steel armor is turned on at full power to provide lighting to Ye Fan behind. The large steel armor walking behind is walking while installing a small locator on the cave wall, and Continuously release sonar to scan the terrain.

When it reached more than 50 meters underground, the air here was very thin, and the traces of the boulders gradually weakened, and traces of steel began to appear.

It is like a large underground fortress built from various huge steel modules.

The air at this time was already very thin. Although the entrance was opened to allow the outside air to flow into the deep underground, it was always limited.

Ye Fan and Tang Xue\'s steel armor, the internal life-saving system has been activated, providing a stable living environment for the two.

After going down almost three hundred meters, the entrance finally reached the bottom.

"Swish!" Two large flares shot out, and the dazzling light released by the flares directly revealed everything here.

At a depth of three hundred meters underground, there is a large pyramid?

What a joke!

"Boss, how can there be a pyramid in this underground?" Tang Xue was also unable to conceal the shock in her heart at this time. You must know whether it is a staircase that extends 300 meters deep, or the vast space under the ground and the pyramid in front of you. , It is no longer something that the ancients could build.

It is also very difficult for human beings with modern technological level to personally end up building such a vast underground space in the soft desert zone.

It can be said that this is an extremely vast project, and the construction of this project cannot be a human being in modern society.

"I don\'t know, it seems that the so-called ancient civilization really exists in this world." Ye Fan was also grimace at this time, and said in a deep voice.

Whether it was the dream of ten thousand years before history, or the energy rifle unearthed from Datang Heavy Industries, or the inexplicable Pisces jade pendant, he guided him along the way.

At this source, there seems to be some mysterious man who cooks **** behind the scenes, who has been guiding him in this direction.

"Boss, it seems that the ghosts that suddenly attacked us on the ground came out from here." Tang Xue glanced at the various "zombies" that came down from the pyramid, and said.

"Well, it seems so." Ye Fan said in a deep voice at this time. Although he doesn\'t know what these things have to do with him, at least from the current point of view ~www.novelhall.com~ still needs to be cleared. Once again.

Ye Fan didn\'t bother to play with them slowly at this time, and directly ordered Origin to adjust the firing rate of the energy rifles of the ten steel armor to the highest.

"Lock the target, lock the target, lock the target..."

Under the control of the superb fire control system, all targets were instantly locked at the same time. In the next second, the energy rifles carried on the ten steel armor began to tilt a large number of death rays at them.

In less than ten seconds, all the "zombies" were killed, leaving only a piece of residue.

No matter your crowded tactics, it can\'t be as fast as my gun.

It was because of the appearance of the Maxim machine gun that the Mongols became singing and dancing, hospitable, let alone more advanced energy rifles.

"Master, according to the scan results of the sonar, there seems to be some special mechanism at the top of the pyramid." The scan results of the origin were uploaded to the inside of Ye Fan\'s steel armor, and the top of the pyramid was marked with a red flashing dot.
