Yin Tian, who was on his way, naturally saw the scene just now. He was worried, but when he saw that Wang Zhengyi had solved the problem perfectly, he was relieved.

It seems that I have underestimated Wang Zhengyi before. I thought he was a mediocre person, but he had a wider relationship with others, and he was also in the light of the king's family in the capital city. Now we can see Wang Zhengyi's performance and know that he also has real skills.

after he had no worries about his future, Yin Tian's speed slowed down a little bit. This is the area of Hata ruins. He thinks that he may find some energy source stones.

The system did not disappoint him. He found the target within 5 kilometers.

"Host, cosmic energy crystal found 80 meters to the right, quantity: 6."

"Ha ha, I'm lucky."

Yin Tian ran to the location of the system guide and dug it up with his hands.

Now he is a bit nostalgic for the former engineer shovel. It's really bad to use his hands to take the yellow sand with 45 degrees in the scorching sun.

"I'll go. It's very hot! Whoa! Whoa

Yin Tian blows hard at his red hands. He feels that if he digs for a while, his skin will burn off.

It's impossible to give up all the energy in front of him. So Yin tiangan Cui took out the blade of time and space and used it as an engineer shovel.

It's a little awkward to use, but it's faster than using both hands.

After a while, Yin Tian dug up a few stone slabs. After he opened them, he found several original energy crystals lying underneath.

"Ha ha, I found it. 1,2,3,4,5,6。 A lot of them

In this way, Yin Tian moved forward in a leisurely manner. He went to play with the original stone of energy. In order to expand the search area, he even used the S-shaped route to catch up.

"Dudu, a lot of energy stones are found ahead! In the calculation of quantity... "

"Dudu, the exact number is 794."

Yin Tian was stunned at the sound of the system.

"More How much? "

"794." The system replied.

"Depend on me! Make a fortune

Yin Tian roars and rushes forward. When he arrives at the other party, he tries his best to dig it up. This time, he makes all the strength of suckling.

A meter of sand on the surface was quickly removed, and a layer of ceramic tiles was exposed below.

Yin Tian regardless of the three seven 21, relying on the sharp edge of time and space, directly cut it into pieces, and then a dark space appeared under Yin Tian's eyes.

"I'll go. It won't be a tomb again, will it?" Yin Tian said strangely.

It seems that his recent missions are related to the tomb. This time, he can't escape this strange circle.

"No matter, go down and have a look first!"

Bang!

Thanks to his bravery, Yin Tian jumped directly.

Fortunately, the black hole is not deep, only more than three meters high. Yin Tian takes out the MP5 behind him, and a tactical flashlight is installed on the guide rail of the gun, which is just in use at this time.

With the light, Yin Tian found that it was an ancient altar, but it didn't look like it.

The ground here is not full of strange gray lines, which are made of strange materials, some like metal, but some like crystal. Then all the lines converge on a stone platform of one meter square.

There is a jade plate on the stone platform. Inside the jade plate, a pile of glittering flying stones are shining. Isn't it the original stone of ability.

"Hehe, hehe, hahaha..."

Yin Tian looked at a pile of ability stones in front of him and couldn't help laughing.

The system upgrade needs cosmic energy crystal. He has got so many of them at once. If he comes several more times, the system will not be upgraded soon.

However, Yin Tian looks at a pile of energy raw stones in front of him, and soon makes a mistake.

He can't take so many with him. Now, except for a few pockets, he has nothing that can offset and hold so much energy.

As for the space of his right hand, ha ha, thank God that the place can hold 100.

"Dudu, the system requires the absorption of type 3 cosmic energy crystal. Please allow the host."

This voice is just Yin Tian's savior. He is worried that he can't take it away.

"Yes! Please absorb it for me

As his words fell, two rays of light came out of his eyes. When the original energy stones met the blue light, they melted at the speed visible to the naked eye like ice blocks meeting hot water.

In just half a minute, all the energy was consumed, as if it had never existed.

"After absorption, the host gains 98 points."

Hearing this, Yin Tian turned his lips and found that the exchange rate was 5:1.

"System, what's the difference between type 3 and type 2? What are these lines on the ground? " Yin Tian finally asked his doubts.The system did not disappoint him. He said directly: "the type 2 cosmic energy crystal is bred by the ability of the planet, and its energy density is very high. Type 3 cosmic energy spar is a kind of high-level life body that collects powerful energy from the universe in a special way, and its energy and purity are far lower than type 2. "

"The grain on the ground is a kind of low-level energy collection device. This kind of simple device is mostly used in low-level civilized planets. It takes ten years to condense a type 3 cosmic energy crystal. This inefficiency has long been abandoned by the higher races in the universe. "

Yin Tian was stunned when he heard this, and his great surprise filled his heart.

Do you mean There have been other civilizations on earth?! Where else does this energy harvesting device come from?

"System, is this energy harvesting device still working? And how long has this thing existed? "

"Back to the host, the device has been damaged for about 180 years and has been in existence for 8120 years." The system replied.

"Sure enough!"

This device condenses 794 energy protoliths, which are at least 7940 years old, which is too far away.

The Chinese nation has existed for 5000 years. When this energy collection device appeared, the ancestors of China should still be living in Yuanmou or Zhoukoudian.

This also proves that human civilization is not the only civilization on earth! There must have been other civilizations in ancient times!

"Earth, how many secrets are you hiding?" Yin Tian murmured to himself.

If he was forced to join the treasure hunter before, he is really interested in this profession now.

What kind of profession can you travel 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 premonition that, in the future, those mysteries that could not be explained by science would slowly fade in his hands!
