"Level 2? What does Level 2 stand for? He Baobao asked.

"Earth humans have just reached the end of Level 1 and the beginning of Level 2." Melancholy said.

"And when you Cybertron perished, how many levels did you reach?" He Baobao asked unwillingly knowing it.

"Level 3." Melancholy replied proudly and dryly.

"This ...... How is this divided? He Baobao looked at Zhuge Hexuan and asked.

"This ...... Let me explain. "According to the pre-1963 Red Empire cosmologist Nikolai Kardashov created an imaginary index to measure the level of civilization in the universe, the Kardashov index is mainly based on the level and total amount of energy available to the civilization. Kardashov originally conceived a three-level model of civilization, which was subsequently expanded to a seven-level model based on more factors. In layman's terms, a Level 1 civilization, also known as a planetary civilization, has the ability to use all the energy on the planet where the civilization is located, including the energy of the outside to reach the planet and the energy generated by the planet itself. And Level 3 civilizations can use the energy of entire galaxies, and can even use unimaginable technologies to extract energy from black holes and artificial stars. The ability of the next civilization is already unimaginable to us, but the scientific community has provided more expansion, the level 4 civilization will be able to control and use the energy of the entire universe, the level 5 civilization may be able to obtain energy from the multiverse, and to the level 6 civilization, we can already discuss the realm of gods, control time and space, and create the universe, and as for the 7 civilizations, the human imagination horror cannot reach that level!"

"Oh my God, my brain is exploding." Listening to Lele's explanation, He Baobao had a headache and pressed his head with his hand, "That is to say, our current level of science and technology is really inferior to primitive people compared to melancholy." But...... But...... Tens of thousands of years ago, they created a civilization that was even more advanced than ours......"

"That's true." Wen Feng leisurely pulled He Baobao and walked back to everyone's side, "What I want to say is, have any of you seen Shen Jie's mercenaries?" ”

Several people immediately realized that since they had entered, no one had paid attention to the traces of the mercenaries who had led them in. Several people looked around at the same time and shook their heads, "They are not here......" Ah Xue muttered as she looked at Zhuge Hexuan and said.

"Looks like they're long gone." Qi Shunji looked at the diamonds all over the ground and wanted to lean down and pick up the diamonds on the ground.

"If they leave, we may not be able to leave safely." Zhuge Hexuan raised the automatic rifle in his hand and scanned the surroundings of the giant tree.

"Perhaps, they didn't notice this secret passage at all and left through another passage." Wen Feng looked at the front of the cave and said leisurely, "Tens of thousands of years ago, the Kak people planted this tree here, and it was never for the purpose of eating people, they must have intended to trade it." ”

"So there's another channel to take away the diamonds? But didn't the hole lead to the seashore when we came? What other passages could there be? Qi Xunsi picked up a large handful of diamonds again, looked at Wen Feng and asked puzzled.

"Level 2 civilization, won't they need to fly?" Wen Feng looked at Qi Xunsi and smiled, "What's faster than flying?" ”

"Fly? You're saying there's another way to the airport? Qi Xunsi grinned at Wen Feng and said, "You're too sci-fi, aren't you?" ”

"Zhuge , take that thing out, it's time to test it." Wen Feng said to Zhuge Hexuan.

"What's that?" He Baobao and Qi Xunsi watched very curiously, Zhuge Hexuan took out a few glasses from the robot dog's backpack.

"What is this?" He Baobao took a pair of glasses handed over by Zhuge Hexuan and asked curiously.

"The definitive version of the Environmental Video Recorder." Zhuge Hexuan grinned and said, "But it took me a lot of time and money." ”

"Ahh Such a big thing is made so small, Zhuge you are really a genius. He Baobao picked up the glasses and couldn't help but say in admiration.

A few people put on their glasses, and a blue transparent image immediately appeared in front of them, only to see those mercenaries holding guns and quickly walking into this huge cave space, followed by one person holding a gun to guard the surroundings, and the other three people immediately lay on the ground and grabbed a large number of diamonds and put them in the tactical backpack.

"They? Why weren't you tempted by the spirit of the giant tree? He Baobao said puzzled.

"They were wearing metal helmets, and they seemed to know what the tree was capable of." Wen Feng said silently.

"No, look at the man on guard with something on his head." Qi Xunsi was speechless and pouted and said. "It's my masking hat."

"Yours?" Zhuge Hexuan looked at Qi Xunsi speechlessly, "You mean this hat is yours?" ”

"Ah...... That thing has been in my house for hundreds of years, I have forgotten its existence, last month someone came to the store and found it in the garbage heap, I forgot what this thing was, casually sold it for 5 yuan as an old thing,, I only remembered that this is a sacred object. Qi Xunsi was lying again and fooling a few people, "This thing is not simple, it can block all the inductive power." ”

"You just can't block out your view, can you?" Wen Feng glanced at Qi Xunsi speechlessly, "You can show it to others, shield a yarn." This must have been sold to the ghost mother and their gang. ”

"Ah...... Don't talk about this...... At that time, I was also a momentary distraction, and I sold such a treasure at such a low price. Qi Xunsi shook his head awkwardly and said.

After the images of the blue mercenaries were filled with diamonds, they stared at the giant tree for a moment, and then ran towards the back of the tree, but the giant tree seemed to sense something, and instantly shot out dozens of seeds, which could be seen The combat quality of those mercenaries, continuous jumping and dodging, and soon disappeared at the end of the cave behind the giant tree.

"Amazing, Zhuge what do you think of their level?" Wen Feng took off his glasses and looked at Zhuge Hexuan and He Baobao with a smile and said.

"It's amazing, at least two people have been shot by seeds." He Baobao said with a look of disdain, "Maybe it's all sprouting now." ”

"So, let's go, let's see if there's any diamonds." Wen Feng smiled evilly and made a gesture towards everyone.
