Jia Zhengjin tried to fill a glass of groundwater with an empty bottle, then held it in front of his eyes and examined it carefully.
[Clear groundwater] has the effect of quenching thirst and cooling.
There is nothing wrong with the water. After taking a sip, it feels like mineral water that has been frozen in the refrigerator, but it is sweeter and more delicious.
This was quite rare, so I took out a large number of empty bottles and collected more than 300 units of groundwater, preparing to take it out for others to taste. I could also send someone back to Holy Dragon City to give Tina and the others a taste.
"Hiss~~" When he superimposed the groundwater on the virtual backpack, a sound suddenly sounded in the water, and then something slowly emerged.
Jia Zhengjin was so frightened that he quickly stepped back and raised his trident vigilantly, ready to fight at any time.
Under his gaze, a strange snake with blue scales all over its body and a particularly smooth feel poked its head out of the underground river and looked at him.
This snake has a round head, so according to theory it should not be a venomous snake. But Jia Zhengjin did not dare to ignore it, after all, everything in the other world is not normal!
First of all, it is very unusual for snakes to appear in underground rivers at this depth!
The snake in Hanoi didn't move, and neither did Jia Zhengjin. Both sides just looked at me and I looked at you.
After a while, whether because of boredom or lack of interest in Jia Zhengjin, the strange blue-scaled snake plunged its head into the water, twisted its body, dived to the bottom and disappeared.
Jia Zhengjin breathed a sigh of relief. Fortunately, this thing posed no threat to him. But he did not dare to cross the river easily again, especially because the water temperature was as cold as an icehouse, which would be difficult for a normal body to tolerate.
I simply built a few wooden frames to build a simple single-plank bridge, passed directly from above, and reached the other end of the underground river.
After arriving, I was even more surprised to find that there was moss everywhere on the ground here, and there were even some strange plants.
There were too many things that challenged his common sense, which made him a little numb. So he stepped on the moss and slowly moved forward. After walking for a few hundred meters, he suddenly became enlightened.
A huge underground cave appeared in front of us, and a strange and beautiful colorful light appeared under the light ball.
When Jia Zhengjin saw the source of the colorful light, his mouth couldn't close at all!
This cave is no smaller than the cave we passed by. It is also very wide and spectacular. The most incredible thing is that all the rock walls around the cave are actually inlaid with various ores that sparkle in the light.
As far as he could recognize, there were silver mines, gold mines, diamonds, iron mines and copper mines, as well as many other ores that he had never seen before, densely packed like decorations, dotting every area.
"Isn't this mineral vein too big?" Jia Zhengjin couldn't help but swallowed, and felt his heart beating wildly. He walked to the edge and stretched out his hand to touch, the minerals felt extremely real, and it was definitely not a dream!
Leaving aside the mines he knew, he used a pickaxe to randomly find some ores he had never seen before, and chipped out some samples to learn more about them.
Carrying [Magic Ore] can increase the magician's elemental affinity, making it easier to practice magic!
[Strength Ore] After carrying it, you can increase your strength and enhance your combat effectiveness!
[Omar Ore] This is a magical additive mineral that can make the weapons you create sharper!
[Karna Ore] This is a magical additive mineral that can make the armor made stronger!
[Titanium Ore] Rare metal ore, very useful.
The properties of these ores excite Jia Zhengjin. Magic ores and power ores can be used to cultivate magicians and warriors. With enough ores, elites can be produced in batches. Coupled with system recruitment, you can have a more powerful army.
Two additive minerals can make weapons and equipment more powerful and are also necessary.
And the titanium ore made him even more excited. Because the titanium alloy made by smelting titanium ore is an essential material for a series of ultra-high-tech mechas, battleships, spaceships, etc. in the later period!
Other ores are fine, but titanium ore must be taken away!
He was very excited and started to dig and collect titanium ore, but found that the more ore he dug, the more ore he dug, and there were even larger reserves of mineral veins behind the rock wall!
It would probably take a long, long time to dig out such a large mineral vein, let alone one person, even if a troop was stationed here. My time is limited and I must leave before dawn. If I am immersed in mining, wouldn't I be unable to find it?
The secret to reaching the deepest place?
Normal people will definitely not be able to enter a place like this, and it is impossible for other forces to come in for mining.
As long as you don't die in the hands of the Dark Dragon, you can come back at any time and transform this place into your own exclusive mine!
For now, let’s ignore these ores and find out the secrets of the deepest places!
Jia Zhengjin finally suppressed his impulse and put away the pickaxe. Jia Zhengjin was very uncomfortable forcing himself not to look at this amazing mineral vein, and finally found another passage hidden in the mineral vein.
Moving forward along the passage, there are still a large number of ores on the rock walls on both sides that are eye-catching, but not enough to highlight Jia Zhengjin's mining ambitions.
After finally overcoming this temptation, I forced myself to move forward, and finally left the mineral vein area, and an even larger underground cave appeared in front of me.
The two previous caves were completely incomparable in front of this huge cave. Jia Zhengjin found that he seemed to be standing on a section of a cliff. Except for the road behind, he could see nothing up, down, left, right, and in front.
"Where should we go now?" The boundless underground cave in front of him made him confused. He thought carefully for a moment, "Since it is an extremely deep place, it should go straight down, right? But it has already flown down just now.
I don’t know how long it will take, are you going to continue flying downward now? When will it end?”
Thinking about it, I saw that it was already two o'clock in the morning. If I hesitated any longer, it might be dawn!
If he can't figure out the secret of the deep place, I'm afraid Jia Zhengjin's curiosity will not be satisfied and he will feel uncomfortable after leaving.
He gritted his teeth and jumped down into the cave, continuing to fall at an extremely fast speed into darkness.
However, this time it was very fast, and it took more than ten minutes to fly before finding the ground. He quickly used the aircraft to control the balance and landed safely, and once again summoned a light ball to illuminate the surroundings.
The moment the light appeared, something suddenly flashed past his eyes. Jia Zhengjin hurriedly raised his trident and looked around vigilantly.
But wherever you look, you can see nothing but rocks.
"Is it an illusion?" Jia Zhengjin, who carefully turned around and found no suspicious creatures, reached out and rubbed his temples, suspecting that he had just been deceived by his senses for a moment.
"Let's look for other passages!" He used the light ball to illuminate and continued to explore.
