To be honest, before they went in, they thought it was just a cultivation tower, not to mention that it could be compared to Da Zhuang, so it would definitely be fine for us to climb three or four floors, right?

As a result, as soon as I entered, I realized that this difficulty was really not something that ordinary people said could easily hit the third, fourth, fifth and sixth floors......

The most important thing is that the strength of these armored wolves has obviously been adjusted, and it is definitely not the LV1 food delivery level.

So the five sand sculpture players began to sit on the ground and study countermeasures-

Su Ying: "The dog planner actually secretly changed the attributes of the armored wolf!"

A group of people nodded violently: "Yes, dog planner!"

Hou Zhitian: "......"

Planning is here, hey, are you really good at saying that?

Zhao Ming: "I think we should have special people to attract firepower, otherwise it will definitely not work to be surrounded by them like this." ”

Su Ying nodded in agreement: "Yes, that's right, so my ice ring can trap them for a while, but you have to come on, I won't be trapped for long." ”

Zhang Yang: "I think, we can consider riding, we used to ride this thing every day, this is inside, you think, if we ride one head, will there be five heads without any attack power?"

Li Tianqi: "I'll lure those five heads away again, there's nothing wrong with Lao Tie!"

Luna: "Then I'll fix one or two more by the way?"

Then several people nodded together: "I'll see it!"

Hou Zhitian and Hong Xiaofu, who have been watching as administrators here: "......"

Do these guys have such a big brain?

If you can't beat it, you can ride?

What the hell?

Then they saw that Zhao Ming and the five of them rushed into the cultivation tower in a hurry.

As soon as the fight started this time, Luna was the first to rush up and find a wolf to ride on, and then Zhang Yang also rode one, and then Li Tianqi took a few wolves to run laps there, Su Ying and Zhao Ming were left alone - they couldn't jump......

Soon there was another burst of white light, and the five of them appeared in the doorway again......

Then he sat on the floor and began to study again: "I think we should do this......"

Hou Zhitian and Hong Xiaofu: "......"

Seeing them tossing over there, Hou Zhitian couldn't help but sigh: "It seems that they still have a long way to go if they want to improve their combat effectiveness......

Hong Xiaofu also nodded: "Yes......"

"Okay, let's not talk about them for now," Hou Zhitian stood up, walked to the windowsill to look at the scenery, and said while watching: "The chief told me that this time the big battle is not so easy to deal with......

He originally wanted to tell Hong Xiaofu to pay attention to safety or something, but before he could finish speaking, he saw the stone chip on the windowsill and asked, "Eh, what is this?"

As he spoke, he picked it up and fiddled with it in his hand.

Hong Xiaofu said: "This is what we found when we were shopping in the market for the first time, and I bought it when I looked very interesting." Uncle Hou, what is this?"

"In the market?" Hou Zhitian hurriedly asked, "Just our bridge platform?"

"That's right," Hong Xiaofu nodded: "Is this thing important?"

"Important, of course very important!" Hou Zhitian immediately became excited, and said, "Do you know what this is? This is a fossil! A fossil in another world!"

Hong Xiaofu was stunned for a moment: "Fossil?"

Speaking of which, he really didn't add it up to that.

But can a fossil be studied?

"Uncle Hou, how do you use this thing?" Hong Xiaofu hurriedly asked, "What kind of energy does it carry?"

"No, it's not energy," Hou Zhitian said excitedly: "This thing represents information, and it represents the information of a certain period of time in a foreign history!" he said and grabbed Hong Xiaofu and asked, "Xiaofu, where did you buy this thing?

"Yes, it's a sister named Tang Lan," Hong Xiaofu said, "I don't know if she's here now, let me ask?"

"Well, you ask right away. ”

While the two walked out, Hong Xiaofu took his mobile phone to contact Tang Lan.

Hong Xiaofu: "Is my sister here?"

Tang Lan: "What's the matter, is someone going to buy stones?"

Hong Xiaofu: "No, there is a leader who wants to see you, at the entrance of the Alien Bridge." ”

Tang Lan: "Oh okay, I'll be there soon." ”

Tang Lan came quickly, and after a while, he walked in front of Hong Xiaofu and Hou Zhitian.

"It's Miss Tang, right?" Hou Zhitian greeted with a smile: "I am Hou Zhitian, an academician of the Huaxia Academy of Science and Technology, and the stone chip you sold to Hong Xiaofu is a fossil after our identification and comparison. I would like to ask Miss Tang, where did you find this fossil, and can you show us there?"

"Huh, that stone flake?" Tang Lan was stunned for a moment, and after thinking carefully for a while, he remembered, and said, "It's the one with the fish on it, right?"

Hou Zhitian nodded violently: "Yes, yes, that's it." ”

"Well, okay," Tang Lan said, "come with me." ”

Tang Lan found the location of the stone shards, in a plain after crossing Sanshui Lake in the eastern part of the Atlas.

The three of them took the rat to a big pit almost half a meter deep, and Tang Lan said, "It's down here." ”

"Is this here?" Hong Xiaofu looked around, and then patted his head the size of a mouse: "Go dig it and see if there are any good things here." ”

Rat Big: ????

Is the master telling me to dig here?!

Rat Da understands! Rat Da is gone!

The rat began to dig a hole, and with its claws, the speed at which it dug into the ground was simply terrifying, and it went down in the blink of an eye!

Tang Lan's eyes on the side were round!

What's going on??A treasure hunting mouse?!

She was summing it up, and she saw that the rat suddenly fluttered out of the ground, and as soon as it came out, it began to spit out of its mouth!

With a click, a stone object fell out of the mouse's mouth!

A fossil!

And then with a snap, it's another fossil!

Rat Big: (′?')

"There really is!" Hou Zhitian said for the first time: "This is a major discovery, we must go back immediately, these things represent great significance, I have to go back immediately and let the Institute of Geology test the age and various composition information of these fossils!"

The age of the fossils!

Speaking of which, this thing is useless for Hong Xiaofu and a few people, it is basically no different from a normal stone, and you have to consider whether it looks good or not when it is an ornament.

But in the hands of Hou Zhitian, it's different, God knows what kind of information they can dig out!

......

Su Ying and the others fought against the monsters in the cultivation tower in the cultivation cabin, and five or six hours passed in this fight.

After all, no matter how you say it, they are all LV2 or above, and Luna is even more LV3, this serious became serious, and it didn't take long to pass the first layer, and the second layer also killed sixteen or seventeen armored wolves. By the time it was time for dinner, they were already standing at the entrance to the third floor.

Coming out of the cultivation cabin, Su Ying and the others glanced at each other, and suddenly laughed together: "Hahahaha! Everyone is cooperating more and more tacitly! This is the real battle!"

Hong Xiaofu said with a smile on the side: "Everyone practiced well?"

"That's pretty good," Zhao Ming was quite satisfied with the performance of the others, "Now everyone knows to protect me while fighting." Speaking of which, it's not bad that I can become a wet nurse......"

Li Tianqi was a little depressed: "It's a pity that my second ability can't be played, otherwise these little beasts won't be enough for me to hammer twice." ”

Several people laughed together.

After dinner, Hong Xiaofu and the six of them went to the big conference room, because they heard Hong Xiaofu say that the stone chip they bought before was actually a fossil!

After waiting for a long time, several people saw Hou Zhitian walk in with a serious face.

"From that stone shard, I found a lot of news. Hou Zhitian looked around the audience and said, "According to the results, this world may be far more complicated than we imagined!"

When he heard this, Hong Xiaofu and everyone were stunned.

What the hell? Can you find so much from a fossil?

"Looking at everyone's expressions, I know that everyone doesn't know much about fossils, which is normal," Hou Zhitian and others all sat down, and said: "Before talking about this fossil, I will give you a brief explanation of the classification of fossils." ”

Everyone listened attentively.

Hou Zhitian said slowly: "Fossils are generally divided into four categories. The first category, solid fossils, refers to fossils in which the organism itself has been partially or wholly preserved. For example, what we often call amber belongs to this category. ”

Amber everyone knew and nodded together.

Hou Zhitian continued: "The second type, called relict fossils, refers to the traces and relics left on the surface or inside the sediment of the substrate due to paleontological activities, such as animal footprints, scratches, crawling marks, and excavated caves, as well as fossils such as eggs, animal feces, and gastroliths. ”

"The third category, chemical fossils, refers to the fact that although the ancient organisms have not been preserved, the organic components that make up the organisms have been decomposed to form various organic matter and are retained in the rock formations, so that the existence of a certain ancient organism can be judged according to this. ”

"And the one we found," Hou Zhitian picked up the fossil in his hand and said, "This is the fourth category, molded fossils, which refers to the impressions and recasts left by organisms in the substrate, surrounding rock, and filling. ”

Everyone listened a little like listening to a book from heaven, but at least they understood that it was a molded fossil.

"Uncle Hou," Hong Xiaofu asked curiously, "Then this molded fossil doesn't sound very high-end, can it observe a lot of information?"

What Hong Xiaofu said was exactly what everyone was curious about.

Such a stone, it looks like it should be...... Not that powerful?

"How can I say it," Hou Zhitian kept playing with this fossil in his hand, and said: "If it is a fossil produced by the earth, it is not unusual, and I can't see anything." But this is a different place, and here is something, and you can see a lot of information. First, let's look at the age of this fossil. ”

He said and took out a piece of information, and said while looking at it: "The Institute of Geology has used isotopes to identify it, and this fossil may not be buried very deeply, but its age is almost between 1.4 billion and 1.6 billion years." ”

Crowd: "!!"

As soon as they heard this number, everyone was completely confused!

Fossils between 1.4 billion and 1.6 billion years old!
