After a short time, the Golden Rat King returned to the ground and handed the small pinch of yellow stones he had grasped in his paw to Jiao Bai. The scorched white pupils that took these "stones" shrank sharply, because these "stones" shimmered with scorching golden light in the sunlight.

"I'll go, Jinsha, it's still such a large grain of Jinsha, it's enough to be called Golden Bean!"

Just underground, there was almost no light, and it was all thanks to the night vision ability of the Golden Retriever Rat King that he could see the general color of these golden sands, making Jiao Bai only think that they were some special yellow stones. Now on the ground, with plenty of light, these golden sands reveal the characteristic golden glow of gold. At the same time, the prompt tone from the system also confirmed to Jiao Bai that this is undoubtedly gold.

"Is the discovery of gold products converted into money?"

Jiao Bai chose "no", and at the same time fell into deep thought, "Why is there so much golden sand in this underground river located deep in the Sahara, could it be that there is an underground gold mine here?" Or is it that this underground river flows slowly, and it has accumulated these golden sands after years of siltation? Whatever the reason, it looks like I'm going to have to go underground. ”

Thinking of this, Jiao Bai left the machine shaft area, found a remote corner where no one was around, and activated the Earth Escape Skill copied from the Golden Rat King, and directly submerged into the earth.

Under the effect of the Earth Escape skill, the surrounding soil is like a yellow viscous liquid, and Jiao Bai is wrapped in this liquid bubble, and quickly moves downward. Tens of seconds later, Jiao Bai had already reached the location of the underground river. In the cold water, Jiao Bai kept paddling his arms, legs and feet to keep his body floating on the surface of the river. At this moment, Jiao Bai's eyes were pitch black, he didn't have the night vision ability of the Golden Retriever Rat King, and he could only use his mental power to avoid some underwater reefs and swimming fish beside him.

Jiao Bai found a set of diving lighting and oxygen supply equipment from his personal space and put it on his body. The moment the spotlight above his head turned on, it was a dazzling golden yellow that almost dazzled his eyes.

"I'll ...... "Jiao Bai just wanted to open his mouth to complain a few words, but he forgot that this was in the flowing river water, even if there was oxygen supply equipment, he poured two mouthfuls of water, and choked very uncomfortable.

After repairing in place for a long time, Jiao Bai was able to breathe a sigh of relief, and at the same time, his mood calmed down a little. He paddled his hands and feet, dived to the bottom of the riverbed, and scooped up a handful of river sand to examine it carefully. I don't know if I don't know it, I was shocked when I saw it, in these river sands, the content of golden sand was as high as more than 5%, no wonder from a distance, there was a piece of golden light everywhere.

Jiao Bai surfaced, and summoned six fat-headed dolphins to explore the past up and down the underground river. The fat-headed dolphin is an authentic sea creature, and its body has been mutated and strengthened, and its swimming speed is much faster than that of Jiaobai. In less than two hours, the fat-headed dolphin was able to detect the underground river for hundreds of kilometers.

After the exploration of the fat-headed dolphin, it was found that in the upper reaches of the river, less than 60 kilometers away from Jiao Bai's location, there is a huge gold vein, and the specific reserves need to be further explored. In the lower reaches of the river, the river flows more slowly, silting up tons of river sand, and the gold content of the river sand is similar to that of the river sand that has just been scorched from the bottom of the river.

The scorched white, which returned to the ground, was still in a huge shock. He didn't expect that under his space base, there was such a huge gold vein, although the specific reserves have not yet been proven, and the gold content of the ore can only be determined by precise measurement and laboratory testing, but only those river sand containing gold found in it, the gold reserves, at least thousands of tons, can compete for a certain ranking in the world gold mine rankings.

"What's next, whether to publish the information about this gold mine and then mine it on a large scale. In this way, my personal assets will definitely increase rapidly, and I can even rank among the top of the world's richest list. It's just that the risk of doing so is not small, not to mention the covetousness of neighboring countries and even Mauria, the world's major mining giants will definitely pounce like sharks smelling blood, and it is not impossible to launch several local wars for this. ”

Jiao Bai thought about it for a long time, but decided to hide the information about the gold mine. It wasn't that he was afraid of those mining giants, or some big capitalists in Western countries, with the massive zombie summoning beasts that Jiao Bai now mastered, even against the regular army of the five major hooligans in the world, he had a great chance of winning, but there was no need to be so high-profile.

The real reason is that Jiao Bai does not want to affect the development of the Sahara space base and the advancement of the aerospace industry. Once the information about the gold mine is made public, no matter whether Jiao Bai can hold this gold mine or not, the construction of the space base located on it will definitely be affected, or even completely stagnant, and the gains will outweigh the losses. In Jiao Bai's view, the benefits brought by the future aerospace industry to Xingchen International are definitely much higher than the value of the gold mine underground.

Of course, not releasing information about the gold mine does not mean that the mine will not be developed. Now that Jiao Bai is worried about the huge amount of money needed to be promoted to an eighth-level evolutionary, this gold mine can be said to be the right time.

It is simply an impossible task for an ordinary entrepreneur, or even some big chaebols in the West, to secretly develop a gold mine of such a huge scale without leaking a trace of information. Jiao Bai is different, he is a summoner himself, and he has a group of absolutely loyal subordinates. Moreover, the zombie team under his command is a group of monsters who do not breathe, eat or drink, and are tireless, and they are the best laborers to develop underground gold mines, and they can work 24 hours a day underground without providing any supplies.

Unfortunately, Jiao Bai does not have the machinery and equipment to mine gold and smelt gold ore at hand, so he can only wait for a batch to be purchased after returning to China before further exploration and gold mining can be carried out. For now, Jiao Bai had no choice but to go to the underground river again, swim to the place where the sand of the river was silted downstream, wave his hand to summon some zombie engineers, and ordinary zombies, distribute them some rudimentary tools, and order them to dig up some river sand first.

After making these arrangements, Jiao Bai returned to the ground and returned to his residence. He was now thinking about whether to go back to China first. The affairs of the Xingchen Group have not been inquired about for two months, and Clark sends a company newsletter to Jiao Bai every week, but Jiao Bai has been very busy, and has only roughly flipped through it a few times. ：，，，
