The protective suits they wore were all from the Tang Sect. The headphones provided simultaneous interpretation, and there was a built-in translation system inside the head shield of the protective suits.
Of course they don't know the language of the Sky Control Clan, but they do have it in the Tang Sect's database. They don't know how it got there, but it's fine as long as they can use it.
From a distance, they were able to reach the Yukong clan base. The base was built with blue metal, which should be made from local materials. However, this is a rare metal! Too luxurious. If Lan Xuanyu refines it, it can be used for spirit and soul forging. The Yukong clan is rich and powerful and deserves its reputation.
From the outside, there is nothing special about the base. It is just a semicircle, like a cover covering the ground. It also looks like a bulge.
At this time, the role of the treasure-hunting beast became more and more obvious. Its spiritual sense was very sharp to all energies. When it was 500 meters away from the base, it reminded Lan Xuanyu and the others to stop, because there was another invisible shield here that was specially designed to protect the base. It also had a reconnaissance effect.
Lan Xuanyu and the other three were also a little helpless. The Sky Control Clan had made the entire Planet 76 like a turtle shell, so it was really difficult to sneak in.
What to do? Wait.
It was impossible to rush in directly. If they were discovered, they would have no chance. They could only wander around the base and look for opportunities.
Lan Xuanyu would never rush in by force unless it was absolutely necessary. That would be a suicidal act. Although his plan was a risky one, he would never take risks easily during the execution, especially when there was no benefit.
The four of them circled around the base and found that the base had a door. If there was a door, it meant that there was a possibility that someone from the Yukong Clan would come out.
So, all they could do now was wait, just outside the semicircular portal they had discovered.
Luck was finally on their side. After waiting for less than an hour, the semicircular door slowly rose up and a tracked vehicle came out. The vehicle looked a bit like a beetle, with an oval back and tracks underneath. The speed was not too fast, but it was obviously suitable for all kinds of terrain.
"Get ready." Lan Xuanyu reminded his companions. They slowly adjusted their positions according to the route of the Sky-controlling Clan's vehicle. The treasure-hunting beast also shared its spiritual perception with Lan Xuanyu, allowing him to feel the changes in the shield.
In a blink of an eye, the vehicle had already reached the shield. A beam of light shot out from the front of the vehicle, and suddenly, a portal was formed in the shield. The vehicle slowly drove out from inside.
"Go in!" Lan Xuanyu said without hesitation. When the car left the shield, they quickly entered. With the illusion of the treasure-hunting beast covering them, they were now completely invisible.
The vehicle left and the shield closed naturally. Lan Xuanyu and the others finally came in.
“Yuge, do the metal detection again. I don’t believe that there is any protection inside their base and on the ground.” Lan Xuanyu said.
Tang Yuge squatted down and used the Five Elements Escape Technique to explore the ground.
After a moment, she raised her head and nodded to Lan Xuanyu.
Lan Xuanyu, Bai Xiuxiu and Yuan Enhuihui were all delighted. The opportunity had finally come. It was hard-won!
"Let's go in together." The three of them still surrounded Tang Yuge. Tang Yuge used the Five Elements Escape Technique and slowly led them into the ground.
Two minutes later, after they had dived about ten meters underground, Tang Yuge stopped. Without him saying anything, Lan Xuanyu understood what had happened, because a stream of white light had appeared under their feet. Protective shield, another protective shield!
"Really..." Given Yuan Enhuihui's personality, he almost couldn't help but swear.
Bai Xiuxiu patted her hood and asked, "Are the Yukong people turtles?"
Even inside the base, more than ten meters deep, there is still a protective shield.
“Everyone, don’t be impatient.” Lan Xuanyu remained calm. “There has always been a protective shield on the ground, which means that our direction is correct. The Void Source Crystal must be underground, otherwise they wouldn’t need such protection. And, if I’m not mistaken, the Void Source Crystal is likely to be found anywhere on this planet. Otherwise, the protective shield wouldn’t be so comprehensive. The Sky Control Clan’s defense is so strict, it must have been sneaked in by other races using various means.”
"I have checked the transaction records of Heaven Star Sky Source Crystal in recent years. From the records, the number of Sky Source Crystal transactions has been decreasing every year. The price has continued to rise. This should be related to the increasingly tight defense of the Sky Control Clan. Moreover, the price speculation is the greatest benefit to the Sky Control Clan. They can quietly release some Sky Source Crystals and make huge profits. Otherwise, how can they be so rich? We are very lucky to be able to sneak in here. Don't worry, Yuge, move sideways and go to the direction of the base. Then, is there any change in the metal composition of this area?"
"Okay." Tang Yuge agreed.
An excellent commander must be able to rally all teammates. After Lan Xuanyu said this, everyone naturally calmed down.
Tang Yuge led the three of them and moved slowly towards the base, while always paying attention to the situation of the protective shield.
"It's still mainly blue copper, but I also found a small amount of magic silver. Although the amount is small, the purity of the magic silver here is very high. It is the highest I have ever seen. It is almost like the essence of magic silver. The purity of this natural magic silver is even higher than that of the magic silver we usually forge a thousand times. This magic silver alone is priceless."
"Um."
At this moment, Tang Yuge stopped. In front of them was a thick blue metal wall. Obviously, they had reached the vicinity of the base from underground.
Lan Xuanyu raised his hand and pressed it on the metal wall, and the treasure-hunting beast's consciousness probed inward, allowing him to see the situation inside.
What surprised Lan Xuanyu was that this base was more like a huge factory than a base.
Compared to the tight security outside, the inside seemed a bit noisy and chaotic. Huge equipment was emitting high heat.
The members of the Sky-controlling Tribe were about 1.5 meters tall, and their bodies were similar to those of humans, except that they had four arms, long legs, and a large head. They had no nose, four eyes, and a large mouth. Behind their heads were tentacles-like things hanging down.
These members of the Sky Control Clan were also wearing protective clothing. Obviously, the environment of Planet 76 was not suitable for their survival either.
There are at least thousands of Sky Control people busy here.
After Lan Xuanyu investigated, he frowned and said, "They seem to be refining metal. But it is definitely not Void Origin Crystal. There is no spatial fluctuation."
"Then what should we do?" Bai Xiu Xiu asked.
Lan Xuanyu said: "We must go in and confirm it. Yuge, follow my instructions and we will find a corner to enter."
Relying on the exploration of spiritual sense, Lan Xuanyu guided Tang Yuge to a corner, and the four of them passed through the wall with the help of golden escape.
Tang Yuge controlled the metal on the wall behind him to restore it to its original state, and only then did they truly sneak into the base.
This infiltration was the most difficult mission they had ever carried out. They used antimatter missiles, the illusion of treasure-hunting beasts, divine sense exploration, and Tang Yuge's five-element escape technique to succeed.
The whole process is really not easy.
The key point is that up to now they haven't even seen the shadow of the Kongyuan Crystal.
The four of them were invisible, and there were no detection devices inside the factory. This was a typical case of tight outside and loose inside.
