"Let's continue to the Spirit Gathering Tower you mentioned, keep them busy here. By the way, I'm going to get you a pair of shoes. Chen Jinnan looked at Yang Xingchen's bare feet and said.

After a while, Yang Xingchen put on a new pair of military boots, and he came to the stone ball mechanism with his memory, and the stone ball had changed back to its original color and no longer glowed.

The huge cylindrical platforms in the round lake have all disappeared.

Yang Xingchen refilled the stone ball with aura, and the mechanism at the bottom of the lake worked again.

Chen Jinnan and the others stared at the huge stone pillar that slowly rose from the bottom of the lake, and sighed at the gap with the aliens in technology.

When all the pillars were raised, the huge stone gate in the lake was opened, and Yang Xingchen was the first to walk up.

Wu Yaoxia wore a spiritual power detector and followed behind Yang Xingchen.

"Brother Xingchen, your current spiritual power is only 80 points, was it consumed when you fought Xuanwu just now?"

"It's only 80 o'clock? I guess that's because I released a lot of aura just now. Although that move is powerful, the aura consumption is also huge, and it will consume 20 spiritual energy points at a time!" Yang Xingchen sighed.

"But that move is so powerful! It's so fast, I don't even see it clearly, what's the name of that move?" Wu Yaoxia asked.

"Name?" Yang Xingchen thought in his heart that this move has no name, it is the first style of the Wind Splitting Fist, how ugly it is to call the first style, and if you have a trick, you still have to take a name for the bright spots, but I will only have this style of the nine styles of the Wind Splitting Fist, and I don't remember the other eight styles at all, so this move will be called the Wind Splitting Fist.

Yang Xingchen himself convinced himself: "This move is called 'Wind Splitting Fist'!"

"Wind Splitting Fist! The name of the move is so handsome, I want to learn it too, Brother Xingchen, can you teach me in the future?" Wu Yaoxia said excitedly.

"Of course you can!" Yang Xingchen said as he walked, walked to the huge stone door that had been opened, and stretched out his legs to step in.

The dazzling light came as promised, Yang Xingchen looked down at the ground, stepped on the stone steps and walked down.

"Everyone pay attention to their step!" Yang Xingchen said behind him as he walked.

"It's so bright inside!" Chen Jinnan hurriedly covered his eyes with his arm after coming in.

"Pay attention to your feet, there is no guardrail here, we have to go down the stone steps, and the light below is not so dazzling. Zhu Yan said beside Chen Jinnan and the others.

"Everyone, be careful!" Chen Jinnan said to the others who had just stepped in.

The group quickly walked more than 160 steps and came to the bottom of the Gathering Spirit Tower.

"This huge device is a fully automatic alchemy device, and the golden pill I showed you last time was refined from this device. Yang Xingchen pointed to the huge mechanical device and said to Chen Jinnan.

"The top part of this huge device is the huge crystal-like thing that will shine brightly, and then there is the top of the tower, where there are many exhaust vents, and the exhaust gas in this spirit gathering tower and everything are exhausted there, and the air in the tower may also be sucked in along with the spiritual energy. Yang Xingchen continued.

Chen Jinnan carefully observed the huge mechanical device in the center of the Gathering Spirit Pagoda and said, "Oh~ This thing is an automated alchemy device, so what is its power? How can it continue to operate like this?"

"The power source may be related to the aura, since it can gather all the aura, then using the aura as a power can be turned into a sustainable energy source, as long as the aura continues, this machine will not stop, I think so. Wu Yaoxia on the side analyzed and said.

"It's quite possible. Chen Jinnan said, "By the way, where are the robots you are talking about?"

Yang Xingchen pointed to the tall lattice warehouse by the stone wall not far away and said, "The robot is there." ”

After he finished speaking, he walked over, and said as he walked: "Before, I guessed that your spiritual power bead might be the power source of this robot, and you can test it today." ”

Chen Jinnan looked at Athena after hearing this, and Athena nodded at him and said, "Well, wait a minute, you can put this bead on the robot and try it." ”

The crowd came to the lattice warehouse, where tall robots stood.

Chen Jinnan looked at the robot, touched his blonde hair, turned his head to Athena and said suspiciously, "Have we seen this shape anywhere?"

Athena stared at the robot for a moment, and then said, "The rock paintings of Helan Mountain! One of them is the appearance of this robot, and there is a person sitting in it." ”

"That's right! It's the He Lanshan petroglyphs! The He Lanshan petroglyphs in the report I saw last time!" Chen Jinnan patted his thigh and said loudly.

Yang Xingchen and others thought that they would say that it was the same as the robot described in the book written by the big boss, but they didn't expect it to be not.

"He Lanshan petroglyphs?" Zhu Yan asked suspiciously, "Is there a robot painted in the petroglyphs?"

"There are many of these robots painted in the petroglyphs, with two lines on their heads like a braid, no lines on their heads, and four lines on their heads like two braids. Chen Jinnan explained: "The petroglyphs of these robots are scattered among the mountain passes of the Helan Mountains in Ningxia, China, and have existed for 5,000-6,000 years. ”

Zhu Yan looked at Yang Xingchen with wide eyes and said excitedly: "5,000-6,000 years ago, aliens were already active there. Xingchen, that's the same as what we guessed before the aliens were active in the era before the Yellow Emperor. ”

"Well, the age of the Yellow Emperor is 4,500 years ago, and the time is consistent. Yang Xingchen said.

"Then do we want to go to He Lanshan to investigate as well, maybe there is a secret realm there. Wu Yaoxia said.

"It's really possible, I'll send someone there when I'm almost busy here. Chen Jinnan said.

Athena took off the necklace from her neck, untied the spiritual power bead, and handed it to Yang Xingchen.

"Go ahead and try it and see if it works. Athena said with a smile.

Yang Xingchen took the spiritual power bead and turned around and walked to the robot's feet.

With a slight jump, he jumped onto the robot's right arm, and with the memory of his dream, he released his aura and touched it in a place below the cockpit.

A small circular metal door instantly shrank in, revealing a circular notch, and there was exactly a circular groove inside, which was basically the same size as the spiritual power bead.

Yang Xingchen put the spiritual power bead in, and the spiritual power bead immediately lit up, and the lines around the circular groove that seemed to have many meridians also lit up.

After a few seconds, the small circular metal door closed again, automatically returning to its original state.

Yang Xingchen activated it with aura on the transparent cockpit canopy, and the entire cockpit began to open upwards.
