The nine pictures let Su Yichen look at them for a full hour, these murals of the Galen people have endured thousands of years, and I don't know how they used to preserve the paintings so well. Given some conditions, there are not many colors in the paintings, but with beautiful lines and realistic images, these paintings can almost be said to be lifelike.

"These paintings are 4,000 to 5,000 thousand years old." Su Li said suddenly, Su Yichen was shocked, and couldn't help but ask: "How long?" ”

Su Li nodded and said, "Judging from the oxidation of color and the weathering of the surface layer of these stones, it is at least more than 4,000 years, you know that the atmospheric environment of this planet is not much different from that of the earth, so my conclusion should be correct." ”

Su Li's conclusion was of course correct, but Su Yichen thought of what Yasuo said to him, according to Yasuo's description, the holy city and the temple have a history of more than a thousand years, but there is still a big difference between a thousand years and 4000 years or even 5000 years.

However, if you think about it, the entire Galen civilization is still in the primitive civilization period, so 4000 years ago, their civilization was even lower, which can be seen from the content of the murals. On the frescoes, the original Galen people were dressed in animal skins, and many even wore a leather skirt around their waists, without even a complete garment. It was only in the later stages of the mural that Galen was dressed in clothes similar to those of today, including the ornate robes worn by the first generation of Yasuo, so that the concept of clothing, or the technique of weaving, was brought about by what they called the gods, that is, the people of the cosmic civilization of unknown origin.

In addition, judging from the mural records, there was no writing in Galen at that time, so they used this relatively primitive way to record the events truthfully. Well, Yasuo, including other Galenites considered more than a thousand years. In fact, it is as early as 4000 years or even longer.

The contents of the murals are easy to understand, and they can basically confirm the guesses of Su Yichen and others. The so-called gods and temples are nothing more than the people of the cosmic civilization and the relics left behind. But there are a few circumstances that make Su Yichen puzzled.

There are three questions that I don't understand, first: Which cosmic civilization is the person of this unknown cosmic civilization, is it an outsider to the Andromeda galaxy like them or a cosmic civilization that is already this galaxy? Where did he come from, why did he land on this planet in this way, and also led the Galenites in the construction of the Holy City and the Temple.

Second: the vast universe in the final picture disappears. Does it mean that the cosmic civilization that came to this planet has left? Where did he go? Why did you leave the planet after building the Holy City and the Temple?

Third: What is the matter with Yasuo in the seventh painting? The other eight paintings are very realistic, except for the seventh painting, the rest of the painting is very abstract except for the figures, what do those chaotic lines represent? Why did he have such a strange and complicated expression?

In addition to these three issues, there are other minor issues, but the rest of the minor issues are not so important compared to the three major issues.

"Dad, there's something strange about this material."

Just as Su Yichen was contemplating and thinking about leaving this room later, Su Li frowned slightly and pointed to the ubiquitous silver parts of the mural, like the shining starry sky.

"Strange? Why? ”

"It's not metal. Because it does not have any characteristics of a metal and at the same time is not a mineral. Su Li replied.

"And what is it?" Su Yichen was stunned, since he came to the temple and saw these starlight-like silver inlays on the surface of the temple, he subconsciously thought that this was a special metal. After all, the universe is vast, especially the Andromeda galaxy, which is far away from the Milky Way, and it is natural that there are some special metal substances in this place. But now Su Li told him that this was not a metal at all, nor was it a mineral like the one used to make pigments, which immediately attracted Su Yichen's attention.

"I don't know. But I feel like it's more of an organic ....... Su Li showed a somewhat confused and uncertain expression.

"Organics?" This made Su Yichen stunned, this is impossible. These murals are more than 4,000 years old, and if they were organic, they would have decomposed! How is it possible that it has survived so long and so far? More importantly, what kind of organic matter has this color? But Su Li's judgment as an intelligent life is not intuitive, it can be said that Su Li's ability alone far exceeds the most advanced intelligent brain in the earth's civilization, coupled with her huge database and analysis skills, the possibility of error is very rare.

I thought about it. Su Yichen didn't figure out what this was, it seemed that he had to find a chance to ask Yasuo. After glancing at the murals around them again, Su Yichen and Su Li pushed the door out, walked through the passage outside, and soon returned to the hall.

Su Yichen these times they went in. Yasuo had been waiting outside, and when Su Yichen and Su Li came out, Yasuo hurriedly greeted them.

"Let's go to the temple." Without waiting for Yasuo to ask, Su Yichen said that his current mind was on the pyramid-like temple, as well as the divine domain mentioned by Yasuo. Now that it has been confirmed that this is a relic left by a cosmic civilization, it is very likely that something will be gained here, and it will even help them return to the galaxy as soon as possible.

Yasuo bowed respectfully, and then led the way, and once again they passed through the central space to the other side, where there was also a door, but this one was a little different from the diagonal door with a fresco, which was carved with ornate patterns.

Standing in the doorway, Yasuo didn't push the door, but raised his hand, the hand that wore the Ring of God. I saw him put his hand on one part of the door, and the door suddenly opened silently to both sides.

After the door opened, there was still a passage inside, and I walked along the passage, and after walking a short distance, the front suddenly opened up. A hall of thousands of square meters appeared in front of them, and in the center of this hall was a pyramid, which was the real temple and the remnants of the civilization of the unknown universe.

When he saw this pyramid with his own eyes, Su Yichen was almost stunned, in the painting, he felt that this pyramid was very similar to the pyramid of the Rand civilization, and when he came to it, he found that this pyramid was almost exactly the same as the pyramid of the Rand civilization.

The size of the pyramid is not to be deduced first, but judging from the structure of the pyramid, it is no different from the pyramids he saw on the base of the earth, including the base of Pluto, and even noticed that there is a small mark in the pyramid book. When he saw this mark, his whole body was shocked.

"Impossible! How is this possible! Su Yichen almost shouted, because this mark was very familiar to him, and it was clearly the mark of the Rand civilization. How could the Rand civilization, which had mysteriously disappeared in the galaxy for a long time and did not know its whereabouts, appear in the distant Andromeda Galaxy?

If this is the relic left by Ike, then maybe Su Yichen will accept it, after all, Ike, as a cosmic explorer, went to the Andromeda Galaxy after leaving the home planet of the Rand civilization. But the problem is that the spaceship on the mural is not the Vanguard he is familiar with at all, and that person is not Ike, could it be that there are other people in the Rand civilization who have come here besides Ike?

The doubts in his heart made Su Yichen a little confused, and he even subconsciously raised his hand and pressed towards the starry sky marker. But unlike the Earth base, including the Pluto base, the star marker did not react, which made Su Yichen wake up from his trance, maybe it was just a coincidence.

"This is the gateway to the Divine Domain, but to enter, you must use the Ring of God to open it." Seeing Su Yichen's subconscious actions. Yasuo explained.

"Turn it on." Su Yichen nodded slightly, took a few steps back, Yasuo saluted him, and then stepped forward to stand in front of the starry sky marker.

As he had opened the door, Yasuo raised his hand with the ring on it, and at the same time he was muttering a word, not knowing what he was reading, it was a strange syllable. The language of the Galen civilization is completely different, and sounds more like a spell than a language. I read a few words. The ring between Yasuo's fingers began to glow, and the starry sky marker lit up as well, and the light between the two quickly merged and intersected.

Just as Su Yichen was staring at all this, the ground suddenly shook slightly, and he was shocked. I saw that the huge pyramid actually began to descend slowly, and at the top of the pyramid a door appeared.

This is a gate that flashes with soft white light, and when he saw this gate, Su Yichen confirmed his guess, this pyramid definitely has a lot to do with the Rand civilization he knows, because this door is both the shape and the way it appears. Even the size of the door is almost exactly the same as the Earth's base.

When the door lit up, Yasuo withdrew his hand, and at this moment he was sweating profusely as if he were about to collapse. It was only ten minutes before and after, and Yasuo actually seemed to consume the strength of his whole body, if it wasn't for the support of his strength, I am afraid that he would have collapsed to the ground.

"O Almighty God! Your most faithful servant, the caretaker of the Divine Domain, has opened the door to the Divine Domain for you. ”

"Are you alright?" Su Yichen didn't look at the door, but asked Yasuo.

"Thank you for your kindness, I'm nothing." Yasuo replied with great joy in his heart.

Su Yichen nodded to Su Li, and Su Li, who knew about it, walked to Yasuo's side without saying a word, stretched out her finger and clicked on his arm, just this, Yasuo first felt a slight pain in his arm, and soon a hot current surged in his body, and the power he had just lost returned to his body, and the whole person was much more energetic.

"How's it going, are you feeling better?"

Seeing that Yasuo's face gradually recovered, Su Yichen asked with concern. Who would have thought that Yasuo was ecstatic and knelt down towards Su Yichen and them again, and said in an extremely pious and thoughtful tone: "Merciful god, your divine power has made your faithful servant feel empowered. ”

Su Yichen couldn't cry or laugh, and he didn't know how to say it. Su Li just injected him with a combination of nutrients and stimulants, which is a special medicine, which is mainly used to quickly repair human fatigue and restore physical strength and mental effects. Because there are often unknowable situations when traveling in space, in case of an eventuality, this medicine can help people a lot.

Asking Su Li to inject Yasuo with Su Yichen was just the idea of being a live horse doctor in front of a dead horse, after all, he didn't know if the potion that was effective for earthlings had an effect on the Galens. However, judging from the current situation, the effect of the medicine is still good, at least Yasuobi is much more energetic.

Waving his hand at Yasuo, motioning for him to rest a little longer, Yasuo seemed to have recovered all his life, and was as energetic as he had been before.

"Come in with us." Su Yichen pointed to the door and said.

As soon as his words fell, Yasuo showed an extremely happy expression, being able to enter the Divine Domain is what every generation of Yasuo dreams of, but except for the first generation of Yasuo, the subsequent generations of Yasuo have not entered.

It's not that they don't want to go in, it's not that they can't go in, according to the scriptures left by the first generation of Yasuo, it is specially noted that if it is not for the guidance of the gods, once they enter without permission, they will not only provoke the anger of the gods, but even completely lose their way directly in the god domain, so that they will fall into the abyss and never be able to come out.

It is precisely this kind of regulation that has allowed Yasuo to open the gate in the past generations, but no one has entered without permission. Before, that is, when he was on the Pioneer spaceship, Yasuo had mentioned to Su Yichen a request that he hoped would be able to follow him into the Divine Domain, but he never expected that it was just a request with almost no hope, and Su Yichen actually remembered, and now offered to let him enter together.

This is an incomparable glory, and it is also the affirmation of Yasuo by the gods, at this moment, Yasuo's heart is extremely excited, and there is pride and pride. Their hard work and maintenance for generations have finally come to fruition today, and he, this generation of Yasuo, can finally follow in the footsteps of the first generation of Yasuo and once again step into the divine realm.

For the sake of safety, Su Li took the lead among the three, Su Yichen walked in the middle, and Yasuo was the last. At the same time, the moment he entered the gate, Su Yichen also turned on the protection of the spacesuit, looking at this gate that was almost the same as the earth base, when Su Li just walked into the gate, Su Yichen followed in at the same time, and the whole gate seemed to have no obstruction, even like air, and it was very easy to enter.

Walking into the door, the scene in front of him suddenly flashed, and when Su Yichen saw the surroundings clearly, he froze, thinking that this would be a small world like the earth base with passages and rooms, or like the ecological balance circle of the base, but these guesses were all wrong, and everything he saw in front of him made Su Yichen unimaginable.
