The protective clothing they wear is from Tangmen, the effect of the headset is simultaneous interpretation, and the head shield of the protective clothing comes with a translation system.

Of course they don't know the language of the Yukong Clan, but the database of the Tang Sect does, and they don't know how it came about, but they can use it.

From afar, they could already see the Sky Clan base, which looked like it was made of blue metal, and it should have been made of local materials. But it's a rare metal! If Lan Xuanyu refines it, this is an existence that can be forged and soul forged. The wealth of the Imperial Sky Clan is well deserved.

From the outside, there is nothing too peculiar about the base, it is presented as a semicircle, as if the hood is covering the ground. It's also like a bulge.

At this time, the role of the treasure hunting beast became more and more obvious, its divine sense was very sensitive to all energy, and when it was still five hundred meters away from this base, it reminded Lan Xuanyu to stop, because there was another layer of invisible shield dedicated to protecting the base. The same is the reconnaissance effect.

Lan Xuanyu and the four of them were also a little helpless, this Imperial Sky Clan made the entire Planet 76 like a turtle shell, and it was really difficult to sneak in.

What to do?

It's impossible to rush straight in, and if you are discovered, there is no chance. They can only wander around the base, looking for opportunities.

As a last resort, Lan Xuanyu would never rush in by force. That's an act of looking for death. Although his plan is considered to be rich and dangerous, he will never take risks easily in the process of implementation, especially not without any benefits.

The four of them circled around the base, and they found that the base had a door. If there is a door, it means that there is a possibility that there will be people from the Yukong clan inside.

So, all they could do now was wait, just outside the semicircular portal they found.

Luck was finally on their side once, and after waiting for less than an hour, the semicircular portal slowly rose, and a tracked vehicle came out of it, which looked a bit like a Beetle, with an oval back and tracks underneath. The travel speed is not too fast, but it is clearly suitable for all kinds of terrain.

"Ready. Lan Xuanyu reminded his partners. They slowly adjusted their position according to the route of the Sky Clan's vehicle. The treasure hunter also shared his divine sense perception with Lan Xuanyu, allowing him to feel the changes in the shield.

Seeing that, the vehicle had already reached the perimeter of the shield, and a beam of light shot out from the front of the car, and suddenly, the shield naturally generated a portal. The car slowly drove out from the inside.

"Enter!" Lan Xuanyu said without hesitation. As soon as the car was out of the shield, they quickly penetrated. Obscured by the illusion of the Treasure Hunters, they are now completely invisible.

When the vehicle leaves, the shield closes naturally. Lan Xuanyu: They finally came in.

"Raing, metal detection again. I don't believe it, there is still protection inside their base, on the ground. Lan Xuanyu said.

Tang Yuge squatted down, cast the Five Elements Escape Method, and probed to the ground.

After a moment, she raised her head and nodded to Lan Xuanyu.

Lan Xuanyu, Bai Xiuxiu, and Yuan Enhuihui couldn't help but be overjoyed, the opportunity had finally come. It's not easy to come by!

"Let's go in together. The three of them surrounded Tang Yuge, and Tang Yuge unfolded the Five Elements Escape Method, and slowly sank into the ground with them.

Two minutes later, after they dived about ten meters underground, Tang Yuge stopped, and without saying anything, Lan Xuanyu also understood what was happening, because under their feet, a white streamer had already appeared. Shield, shield again!

"It's really ......" Yuan Enhuihui's character couldn't help but almost swear.

Bai Xiuxiu patted her hood, "Is the Imperial Sky Clan a tortoise?"

Even inside the base, at a depth of more than ten meters, there is still a protective shield.

"Don't be impatient, everyone. Lan Xuanyu was still very calm, "There has always been a protective shield on the ground, which means that we are in the right direction." The Sky Source Crystal must be underground, otherwise they wouldn't need such protection. And, if I'm not mistaken, it's likely that the Void Crystals are available anywhere on this planet. Otherwise, the shield wouldn't be so all-round. The defense of the Imperial Sky Clan is so strong, it should have been stolen in by other races and infiltrated by various means. ”

"I've checked the transaction records of the Heavenly Starry Sky Source Crystal in the past few years, and judging from the records, the number of transactions of the Sky Source Crystal is decreasing every year. Prices continue to climb. This should have something to do with the fact that the Sky Clan's own defenses are getting tighter and tighter. And the price speculation is up, and the benefits to the Yukong clan are also the greatest. They can completely quietly release some empty source crystals and make huge profits. How else would we be rich? We're lucky to be able to sneak in here. Don't rush, rain grid, move sideways, go in the direction of the base. Then see what happens to the metal composition of this piece. ”

"Good. Tang Yuge agreed.

A good conductor will be able to unite all his teammates. As soon as Lan Xuanyu said this, everyone naturally fell silent.

Tang Yuge led the three of them to move slowly in the direction of the base, while always paying attention to the situation of the protective shield.

"It's still mainly blue pregnant copper, but I also found a small amount of magic silver, although the amount is not much, but the purity of magic silver here is very high. It's the tallest I've ever seen. It's almost like a magic silver essence. The purity of this natural magic silver is even higher than what we usually have after a thousand forgings. This magic silver alone is also priceless. ”

"Hmm. ”

At this moment, Tang Yuge stopped, and in front of them, there was a heavy blue metal wall, obviously, they had reached the vicinity of the base from the ground.

Lan Xuanyu raised his hand and pressed it against the metal wall, and the Treasure Hunter Beast's divine sense probed inward, allowing him to see the situation inside.

To Lan Xuanyu's surprise, in this base, it was not so much a base as a huge factory.

Compared to the tight protection outside, the inside is a bit noisy and chaotic. Huge devices exude high heat.

The height of the Yukong clan is about 1.5 meters, and the body size is somewhat similar to that of humans, but they have four arms. Longer legs. The head is huge. He has no nose and four eyes and a large mouth on his head. Behind the brain, a tentacle-like presence hangs down.

These Sky Clansmen were also wearing protective suits, and it was clear that the environment on Planet Seventy-Six was also unsuitable for them.

There are at least a thousand Yakuza people busy here.

After Lan Xuanyu investigated, his brows frowned slightly, and he said, "They seem to be refining metal. But it is certainly not an empty source crystal, and there are no spatial fluctuations. ”

"Then what should we do?" Bai Xiuxiu asked.

Lan Xuanyu said: "You have to go in and have a look, confirm it." Yuge, you follow my guidance, let's find a corner and enter. ”

With the exploration of his divine sense, Lan Xuanyu guided Tang Yuge to a corner, and the four of them entered through the wall with the help of Jin Dun.

Tang Yuge controlled the wall behind him to restore the metal to its original state, and they could be regarded as truly infiltrating the interior of the base.

This infiltration was arguably the hardest mission they had ever performed. It used antimatter missiles, the illusion of the treasure hunting beast, the divine sense detection, and Tang Yuge's Five Elements Escape Method to succeed.

The whole process was really not easy.

The point is, so far they haven't even seen the shadow of the empty source crystal.

The four of them have a stealth effect, and inside this factory, there are no detection devices. This is typically tight on the outside and loose on the inside.
