Hu Yihu arranged for the soldiers to assist the astronauts in a new generation of spacecraft developed with the help of the clones, and was sent directly to Europa on a mission, his mission was to collect the secrets contained in the pointed building, and also carried some experimental items required by the clones. The ship headed for Europa as fast as it could......

Europa, the astronauts further analyzed the data they received, and the probe brought back some of the liquid that had flowed from the soil and ice around the building. The astronauts opened the collection box and removed the specimens. Put it into an instrument, and then open the smart calculator and start running, the numbers on the display began to roll one by one, in addition to hydrogen molecules and oxygen molecules, there are eight more elements that have never existed on the earth, those elements are constantly combining and tumbling in it, they will continue to shrink and expand like a web, the detector tests the reaction of the liquid, and shines a variety of different light on the liquid. The reaction of the liquid to these rays varies, when the rays are illuminated with weak light, the liquid state does not show any reaction, and when the rays reach a certain value, the combination of those elements becomes faster and faster, and the form of the liquid disappears immediately, and the form displayed in the detector becomes a stone, which will also change into various irregular patterns in this particular ray, and the rays will stop, and the liquid will return to its original state. The astronaut quietly watched what was happening in front of him, and felt very incredible.

Tucker soon received Europa's test data, and the supercomputer recalculated and arranged all the elements contained in the liquid, and the results showed that some of the new elements produced by the combined combustion in the study were very similar to those in their liquid form, and that those liquid elements were most likely the new fuels that humanity was looking for. The clones also felt very peculiar about the arrangement of these elements, which was not seen on Gliese 581d. Pan Liang randomly ordered Lookout 1 to collect a ton of liquid and transport it back to Earth for research.

In the gate of time, the four of them walked along the mirrored sea, stepping on the sea as if walking on the floor, but there was a cold feeling, the body would not sink at all, walked for about 5 hours, and found that the water on the ocean surface continued to surge forward in one direction, but the water did not form waves because of this, but just formed a straight line to flow to the center, and it was obvious that there was a huge whirlpool in the middle of the ocean in the distance......

The closer to the position from the center, the more turbulent the water flow became, and the clone used the ability to fly to take Liu Fei into the air, several people hovered in the air, looking at the direction of the water flow, looking down from the air, there was a huge abyss in the center of the ocean, and the clone suddenly remembered the one that appeared in the upper layer of Glize 581d, which looked the same here; The water continued to flow into the abyss, forming a huge circular waterfall, and due to the refraction of light, eight rainbow bridges appeared on the edge of the waterfall. The clone then took a part of the water and put it in the bottle, and as soon as he poured it, the bottle shook, and the paper in the bottle kept spinning inside, turning faster and faster, and the bottle containing the liquid immediately suspended in the air, and the liquid suddenly sprayed out of the bottle like a fountain, and the liquid droplets instantly solidified into leaves in the air, and the bottle became a tree trunk, and a tree appeared in front of their eyes.

"Isn't this the tree we see on the core? How did it come out here? Liu Fei asked

"This is a testament to our prophecy that the liquid of the ocean of memory will only appear when the one who saves it comes." Clone A said

"You're the one who saved the world." Clone B said

"What and what is this?" Liu Fei said

"We're trapped now, what's the question of saving or not saving, and now it's imperative to get out of this damn place, I'm tired of staying." Liu Fei continued

"The Sacred Tree will only appear when the Saved One appears, and the Sacred Tree can help you fulfill both wishes." The clone continued

"So, this bottle is inextricably linked to the sacred tree, don't you still have a bottle on you? Take a few more and put them to the test! Liu Fei said

"The sacred tree does not appear casually, and those who see it are either blessed or calamitized."

"We've seen this tree on the silver core, and a large number of eagles have died, and I've only seen disaster, blessing?! I can't even think about it. ”

At this time, the sacred tree stood quietly on the ocean surface, the leaves swayed gently with the clear wind on the ocean surface, and the liquid flowing along the abyss suddenly all flowed towards the center of the tree, slowly forming a huge whirlpool around the tree, and the liquid rushed up from the ocean level like a dragon, and turned into a solid figure-eight shape around the tree, and the water was flowing rapidly. Faces gradually appeared in the liquid, and the faces shuttled back and forth.

"Why are there so many faces? It's unbelievable. Liu Fei said

"Hello, it looks like thousands of years have passed, I've been waiting here for a long time, and now I'm finally free." The sacred tree made a sound

"Hello, we want to know what's really going on here, and why do all people need to use the memories of people on Earth? Why do so many bottles keep popping up, and why do I see people I know here?" Liu Fei asked

"We've been here since the planet was born, and at first it was peaceful, and the people lived very happily. Due to a superstar impact, more than 80% of the species on the planet were wiped out, and the remaining 20 could only survive on the little remaining resources on the planet, but the situation was very bad, and soon the remaining 20% quickly declined, and finally only 203 people survived with the efforts of everyone, this is the brother star of Gliese 581d, in order to make the planet more suitable for survival, everything is made according to the standards there. That's why we also call it the Gliese 581D. ”

"I see. We want to know where the signals of these memories are transmitted to Earth?"

"The Abyss"

"This is the closest passage to the silver core, and it is also the source of signal transmission, the water of the abyss flows directly to the factory water source of the silver core, and the signal is also constantly sent out through here, and then the silver core is combined together."

"Understood. We do not want to see disaster for our own people, nor do we want to see disaster for the people here. Is there any way to do it? In addition to turning off this signal. Liu Fei asked

"From here, the letters were sent out in a steady stream, all the way to Earth in Gliese 581d, in search of help. The only hope for the people here to suffer disaster is for them to move away. ”

"How long can they last without memories?"

"It won't last long here, but they can get out of the environmental constraints here."

"What do you mean?"

"A small satellite on the edge of Y3, that star is enough to sustain all the people on this planet now."
