Sure enough, as Guo Qingyang entered the huge cave, the surrounding Protoss didn't notice anything unusual at all, and still maintained the original vigilant formation. Pen & Fun & Pavilion www.biquge.info

Guo Qingyang had to say that the stealth technique he had newly comprehended was really too strong, and he was afraid that it was no less than the stealth technique performed by the god general of the Protoss at the beginning.

You must know that Guo Qingyang absconded to the deep underground at that time, and the spiritual force field had been shrouded in a thousand kilometers around him, but he didn't notice how the god general was chasing him.

If it weren't for the fact that the god general launched an attack on Guo Qingyang, he wouldn't have sensed that an uninvited guest had arrived beside him.

And now that Guo Qingyang also has such a miraculous stealth technique, it is basically impossible for these gods to discover his arrival.

Of course, the premise is that Guo Qingyang can't launch an attack and take the initiative to expose his existence, otherwise, even if he has a supernatural stealth technique, it will not work at all.

The space under the mine is very wide, and it is not at all the scene of a cramped and narrow tunnel spreading endlessly underground, as Guo Qingyang imagined.

It is also said that with the scientific and technological strength and individual ability of the Protoss, it is too easy for them to dig such a huge mine hole underground.

Moreover, the tools used by the Protoss to transport ore are also very large, and if there is no such a wide mine, those tool vehicles would not be able to enter and exit at all.

Not long after, Guo Qingyang had already come to the depths of the cave, and on the nearby cave wall, he saw the veins of the mysterious mineral deposit.

Completely different from the surrounding gray rocks, a vein of silver-blue metal is scattered in the endless rock formations, which looks extremely eye-catching.

"What kind of mineral deposit is this, which has attracted the Protoss to come here from hundreds of millions of light-years?"

Guo Qingyang looked at the ore veins in the rock formation, took out the black flying sword and cut off a piece of ore, put it in front of him and looked at it carefully, but found that he didn't know this kind of mineral deposit at all, it was obviously a new type of mineral that was not available in the earth world and the Cangzhou continent.

"Congratulations to the host for completing the second mission in this world, discovering a vein of green silver, and receiving the reward: the world's mineral knowledge encyclopedia."

As this piece of silver-cyan ore was held by Guo Qingyang in his hand, a system prompt sound quickly sounded in his ears, indicating that he had completed the second task of this world.

"The World's Mineral Knowledge Encyclopedia? Well, that sounds like a useful thing! ”

After Guo Qingyang was slightly stunned, a look of ecstasy appeared on his face, and with this "Encyclopedia of Mineral Knowledge in the World" rewarded by the system, it was clear what the specific role of this ore called Qingyin in his hand was.

Consciousness sank into the sea of knowledge, and Guo Qingyang really found that there was a mysterious ball of light in it.

As soon as his consciousness came into contact with this mysterious light, he immediately had a lot of knowledge about the identification of minerals in this world in his mind.

It took some time, and after Guo Qingyang thoroughly absorbed this knowledge, his eyes stared at the lapis mine in his hand, and a hint of understanding appeared on his face.

Lapis is one of the rarest mineral deposits in the world.

Purified blue silver is extremely rare, it has both extremely light weight and impressive toughness, making it one of the best metals for making warships.

Of course, it would be too extravagant to make a warship out of this extremely rare metal, and generally speaking, a small amount of blue silver is inserted into the alloy in proportion to improve the performance of the alloy in all aspects.

Of course, if it was just that, the lapis mine might not be so attractive to the Protoss, and its other two attributes were the best.

First, blue silver has excellent memory, and when mixed with other metals according to the ratio, it can greatly improve the memory of metal objects, which can greatly improve the defense of the battleship's armor.

Finally, and one of the most critical attributes of green silver, is that it has excellent energy conductivity.

The key to why those machines of the Protoss can have a powerful energy defense shield is in the magical mineral deposit of green silver.

However, since there is such a magical deposit as lapis here, why did the Alfa have not found it here at all after nearly 20 years of development?

After thinking about it slightly, Guo Qingyang immediately understood, it was really because the lapis mine here was buried too deeply, at least dozens of kilometers underground, and it was full of ordinary rock formations, which was too confusing for mineral exploration.

Probably because when the Alfa was exploring this place, they thought that there were no mineral deposits in this place, so they passed by this priceless vein?

After understanding the value of the lapis mine, Guo Qingyang immediately used his divine sense to scan the surrounding rock formations, and found that along this position, among the rock formations that were more than ten kilometers deep, there were actually veins of the lapis mine.

Although the content of green silver in these green silver ores is not very high, the total amount of green silver is definitely an eye-catching level.

It is no exaggeration to say that the overall value of the lapis mine contained in this place is simply astronomical, and can make anyone one of the richest people in the Alpha System.

More importantly, the strategic significance of this green silver deposit is not trivial.

If the Alpha Federation knew about the situation here, it would definitely send a large number of fleets at all costs to take this planet back from the hands of the Protoss.

"Okay, now that we have found out the situation here, then let's go up and harvest the lives of those Protoss and provide supplements for the Ziyun Dan Sutra!"

Although Guo Qingyang is very fond of this vein, with his strength alone, it is not enough to mine it, and he doesn't have so much time to spend here.

Therefore, it would be the best plan to drive away the Protoss above and send the news back to the Alpha Federation through the Redeemer's camp.

According to the Alpha Federal Mineral Mining Regulations, Guo Qingyang, who was the first to discover this vein and made great contributions, will be able to enjoy one-tenth of the rights and interests of this vein in the future.

In this regard, what else is Guo Qingyang not satisfied with?

When Guo Qingyang came to the surface again and suddenly launched an attack on the Protoss camp, the entire Protoss camp exploded at once, except for leaving a group of small warships with a large number of flying saucers to resist Guo Qingyang's attack, all the large and medium-sized warships quickly evacuated towards the sky.

During the whole process, the Protoss did not show a trace of indecision.

As a result, Guo Qingyang's final harvest was minimal, especially those large warships loaded with a large amount of green silver ore, and even more so that none of them could stay.

"What a terrible race!"
