Chapter 90: Yin Tian’s Super Harvest

　　 Yin Tian, ​​who was on the road, naturally saw the scene just now. He was very worried at first, but he was relieved after seeing Wang Zhengyi's perfect solution.
　　 It seems that I had underestimated Wang Zhengyi before. I only thought that his cultivation level was average, but his connections were broadened. At the same time, he was exposed to the light of the king of the capital. Now that I see Wang Zhengyi’s performance, I know that he also has real talents
　　 After the worries were gone, Yin Tian's speed slowed down a little bit. This area of ​​a hundred li is the area of ​​the Hata Ruins. He felt that he might find a few rough energy stones.
　　 And the system did not disappoint him, so he found the target after walking less than 5 kilometers.
　　 "Host, a cosmic energy spar was found 80 meters in front of the right, quantity: 6."
　　 "Haha, I seem to be lucky."
　　 Yin Tian hurried to the position indicated by the system, and dug up with his hands.
　　 He missed the former engineer shovel a bit now, and under the scorching sun, he used his hands to shove the forty-five degrees yellow sand, which was really uncomfortable.
　　 "I'm going to burn people to death! Huh! Huh!"
　　 Yin Tian blew hard into his flushed hands. He felt that he would have to scald the skin after digging for a while.
　　 It is impossible to give up the rough energy stone in front of him, so Yin Tian took out the Blade of Time and Space and used it as an engineer shovel.
　　 Although this thing is a bit awkward to use, it is faster than using both hands.
　　 After a short while, Yin Tian dug a few stone slabs. After he opened it, he found a few rough energy stones lying underneath.
　　 "Haha, I found it. 1, 2, 3, 4, 5, 6. A lot of one!"
　　 Yin Tian just moved forward unhurriedly, and went to play with the rough energy stone. In order to expand the search area, he even used an S-shaped route to drive.
　　 "Beep, a lot of rough energy stones are found ahead! The number is being calculated..."
　　 "Dudu, the exact number is 794."
　　 Yin Tian was stunned when he heard the sound of the system.
　　 "More...how much?"
　　 "794." The system replied dumbly.
　　 "Damn! I'm rich!!"
　　 Yin Tian roared and rushed forward, digging hard when he reached the opponent, but this time he used all the power of feeding.
　　 One meter of sand on the surface was quickly cleared, and a layer of ceramic bricks was exposed below.
　　 Yin Tian didn't care about the three seven twenty one, relied on the sharpness of the blade of time and space, and directly cut it into pieces, and then a dark space appeared under Yin Tian's eyelids.
　　 "I'm going, isn't this the tomb again?" Yin Tian said incredulously.
　　 It seems that his recent missions are all related to the tomb, so he can't escape this strange circle this time.
　　 "No matter what, let's go down and have a look!"
boom!
　　 Relying on the courage of the art master, Yin Tian jumped directly down.
　　 Fortunately, this black hole is not deep, only more than three meters high. Yin Tian took out the MP5 behind him and installed a tactical flashlight on the rail of the gun, which came in handy at this time.
　　 With light, Yin Tian discovered that this place turned out to be an ancient altar, but upon closer inspection, it did not look like it.
　　 The ground here is dissatisfied with weird gray patterns. These patterns are made of strange materials, some like metal, but some like crystal. Then all the lines converge on a stone platform one meter square.
On the 　　 stone platform, there is a jade-colored plate. Inside the jade plate is a pile of glittering flying stones gleaming, isn't it the rough stone of ability?
　　 "Hey, hey, hahaha..."
　　 Yin Tian couldn't help laughing wildly as he looked at the pile of rough stones in front of him.
　　 The cosmic energy spar needed for the system upgrade, he got so many all at once. If this happens a few more times, the system upgrade will not be quick enough.
　　 But Yin Tian looked at the pile of rough energy stones in front of him, and soon made trouble again.
　　 He can't take so many with him. Now, except for a few pockets, there is nothing on his body that can offset it and hold so many rough energy stones.
　　 As for the space in his right hand, hehe, thank goodness that the place can hold a hundred.
　　 "Beep, the system requires the absorption of Type 3 cosmic energy spar, please allow the host."
　　 This voice is simply Yin Tian's savior, he is worried that he can't take it away.
　　 "That's it! Get me absorbed quickly!"
　　 As his words fell, two rays of light shot out from his eyes. After the rough energy stones encountered blue light, they melted at a speed visible to the naked eye, like ice cubes meet hot water.
　　In just half a minute, all the raw energy stones were consumed, as if they had never existed.
　　 "After the absorption is completed, the host gains points: 98."
　　 Yin Tian curled his lips when he heard it, and it turned out to be a 5:1 conversion ratio.
　　 "System, what is the difference between Type 3 cosmic energy spar and Type 2? What are these lines on the ground?" Yin Tian finally asked the doubt in his heart.
The system didn’t disappoint him either. He said directly:
Type 2 cosmic energy spar is bred by the planet’s ability and has a very high energy density. Type 3 cosmic energy spar is a collection of powerful energy in the universe collected by advanced life forms in a special way~ EbookFREE.me~ Energy and purity are much lower than Type 2."
"The lines on the ground are a kind of low-level energy harvesting device. This kind of simple device is mostly used on low-level civilization planets. Race abandonment."
　　 Yin Tian was stunned when he heard it, a huge surprise filled his heart.
　　 Could it be said that there have been other civilizations on the earth? ! Otherwise, where did this energy harvesting device come from?
　　 "System, is this energy harvesting device still usable? Also, how many years has this thing been in existence?"
　　 "If you return to the host, this device has been damaged for about 180 years, and its existence is 8120 years." The system replied.
　　 "Sure enough!"
　　 This device has condensed 794 energy rough stones, which have existed for at least 7940 years, which is too far away.
　　 The Huaxia nation has only existed for 5,000 years. When this energy-harvesting device appeared, Huaxia’s ancestors should have lived in Yuanmou or Zhoukoudian, living a life of drinking blood.
　　 This also proves that human civilization is indeed not the only civilization on earth! Other civilizations must have appeared in ancient times!
　　 "Earth, how many secrets are you hiding?" Yin Tian muttered to himself.
　　 If joining the treasure hunter was a last resort, then he is really interested in this profession now.
　　 I would like to ask, is there any profession in the world that can wander around the world like a treasure hunter, looking for all kinds of strange treasures and exploring the unsolved mysteries in the world?
　　 Yin Tian even had a hunch, maybe in the future, those puzzles that science can't explain will slowly fade away from the mysterious veil in his hands!
