In central Africa, in the barren desert, there is a huge circular cavity, and sand and gravel are constantly thrown outward underneath.

At 1,431 kilometers below the surface desert, Chen Rui is urging the Escape Tissot to keep digging down.

"The trick of drilling the mountain cone is really a magic skill of plowing the ground, fortunately there is this trick, otherwise we don't know how much the efficiency of plowing will be reduced!

"In the past four years, we have been to a lot of ruins, but unfortunately there are too few ruins to enter, and the quality of the treasures found is not very high, this is the last ruins, don't let me down!"

Two years ago, the Black Dragon Mountain-X81 spacecraft had been repaired, and Chen Rui could set off for the universe at any time. But in order to accumulate more capital, he still relented and slowly explored the underground ruins.

However, since these underground ruins can survive the destruction of the earth, they are naturally extremely strong. With Chen Rui's Xingxing-level strength, as long as the ruins themselves were not damaged, he would not be able to enter them at all.

So much so that in the first two years, he got nothing. He almost had the idea of giving up.

But when he thought that after all the assets in his hands were sold, they would not be enough to buy the earth, so he could only hold on.

But just a year ago, following Nacia's instructions, he actually found a broken ruin. It was a custom-built super-high family fortress, which, according to Nacia, was previously owned by a realm lord.

In the ruins of the family fortress, Chen Rui found 12 third-order Force weapons, 3 third-order telekinetic weapons, and 1 fourth-order Force weapon.

After exploring, Chen Rui also complained that the realm master was too poor.

But after thinking about it, this realm lord should have brought all the valuable treasures with him. What was left in the family fortress were items that he didn't need himself.

However, as long as the 4th order Force weapon is disposed of, the money to buy the Earth should be enough.

At this time, Nacia's slightly clipped-tone voice sounded in Chen Rui's mind:

"The owner of this relic is the Earth Leader of the 7th Earth Civilization Era, a top realm lord with wealth comparable to that of ordinary immortal powerhouses. It's not comparable to the realm lord of the previous family fortress. If we can get into it, the harvest will definitely be not small.

"With this realm lord's level of law comprehension, he would definitely be able to break through to the immortal level, but then I heard that he went to a Jedi called Star Tower on the extraterritorial battlefield, and he never came back. I guess I died in the Tower of the Stars.

"In the previous 3rd Earth Civilization Era, there was an amazing immortal powerhouse, but I heard that he also died in the Star Tower of the extraterritorial battlefield.

"Except for these two powerhouses, there have been no other supreme geniuses on Earth. This Star Tower is really an evil sect, and the only two supreme geniuses on Earth have died there. Master, if you become a strong man in the future, I don't think you should go to the Star Tower, this thing is too weird, maybe there will be some conspiracy against the earthlings. ”

Chen Rui nodded and responded: "Don't worry, I know it in my heart." ”

It turns out that the owner of this ruin is the second candidate for the Star Tower, so he should indeed be very rich.

It's a pity that the first Star Tower candidate left no traces. Listening to Naxia, that immortal powerhouse was bent on pursuing martial arts, and did not leave behind heirs and family inheritance.

"Ding!"

"Ding!"

At this moment, there was a sound of metal colliding below, and Chen Rui was overjoyed, it seemed that he had dug up the ruins!

He immediately urged the Escape Tissot to cut away all the dirt and stones that wrapped the ruins.

After a while, a tall fortress of survival appeared in front of Chen Rui's eyes.

"It's actually such a super-high survival fortress again, it seems that it is estimated that the effort will be in vain again."

Chen Rui frowned and flew around the survival fortress a few times, and suddenly, a smile bloomed on his face.

He saw that there was a gap at the bottom of the survival fortress the size of three people, and he didn't know if it was destroyed by man. But it didn't matter how he destroyed it, as long as he could find an entrance into the fortress of survival.

Chen Rui immediately flew towards the gap and smoothly entered the interior of the survival fortress.

"Master, according to the structure of this type of survival fortress, the most important treasure room is usually located in the middle and rear of the fortress, and the exact location I have marked. Let's go straight there! ”

After Chen Rui received the electronic mark, he did not hesitate, and went around inside the survival fortress and ran straight to the destination.

Along the way, he didn't see any corpses, presumably weathered after so many years.

There are quite a few metal robot guards that are still intact, but they are no longer mobile.

"Master, the level of these metal robot guards is not low, the lowest has A9 level, and the highest has C9 level, which is comparable to the ninth order powerhouse of the universe level. Thankfully, after all these years, the energy source in their bodies has long been depleted, otherwise we wouldn't have been able to sneak in. I'll put them away first, these metal robots are worth a lot of money! ”

With that, Nahya included all the metal robots that had fallen along the way into the World Ring.

After a short time, Chen Rui came to the door of the treasure room, but the door of the treasure room was tightly closed.

"What now? With my strength, I will definitely not be able to penetrate this gate. ”

Nathea responded:

"The strongest thing about this kind of survival fortress is the outer structure, but the quality of the various structures inside the fortress is not too high, at most it is about the same as the material of the gate of the Black Dragon Mountain-X81 spaceship. You can stick this giant top into the crack in the door and give it to me. ”

Chen Rui also reacted when he heard this, the most important thing in the survival barrier is the outer layer, as long as the outer layer is solid, there will be no problems inside. The quality of the interior building is not important.

In front of him, a strange tool appeared.

This tool resembles an axe, with an extremely thin blade. Before opening the floodgates of Heilong Mountain-X81 spacecraft, it was also by this tool called "Juliding".

Chen Rui knew the use of this tool, so he picked up the giant force top and directly inserted the thin axe blade into the crack of the door.

"Huhuhuhu-"

Ju Li Ding made a strange sound, and the door of the treasure room was forced up.

Chen Rui slowly stepped into the threshold, his gaze swept towards the treasure room.

I saw that there were not many things placed in the treasure room, only three objects lying quietly on the platform in front of them.

On the right side of the platform is a pistol-style firearm.

On the left is a war knife.

In the center is an earthy yellow club-like weapon.

Before Chen Rui stepped forward to check, Nacia's excited voice sounded in his head:

"It's actually a D6-level laser gun, a Sky Splitting Knife, and a Wall Divine Weapon. The hosts, we send, we send! In the past four years, I have been digging underground ruins day and night, but it is not in vain!

"I was worried that the realm lord had brought all the good things with him, and he didn't leave anything behind! Now it seems that although the things here really don't match the status of the Invincible Realm Lord, he still left some good things for the family! ”

"D6 level laser gun, I know, this should be a technological weapon that can kill the domain master's 6th order powerhouse. But what are the other two? ”

Although he has not yet received a reply, Chen Rui is also excited at this time. What can be put together with the D6 laser gun will definitely not be an ordinary treasure!
