In the darkness, a giant arch with an arc top more than thirty meters high above the ground stood quietly, emitting a brilliant blue light under the illumination of several pillars of light crystal cylinders.

"This looks like a door~" The elf stood by one of the doorposts of the arch, looking up at the blue runes on the door frame.

"That's what you've come all the way underground to find, isn't it?" Ella asked, looking back.

Lin Ze looked at the arch in a daze, as well as the runes that reflected the blue light, and only after a while did he sigh dejectedly, "No! At this moment, there are no names such as Moon Creek, Rain Leaf, Fang Qi and other names in his mind, only a faint loss remains, it turns out that it is not a plane portal, this must be Shuangshu City, so it seems that I am afraid that the portals of several other cities should also be this kind of interstellar portal, think about it, plane teleportation requires a sixth-order civilization to access, and Lin Ze has only seen the fourth-order technology of the Moon Elves, the Moon Yaojing Technology and the Moon Silk Cloth Technology, if the fourth-order civilization is a fourth-order civilization, it is already very reluctant to be able to initially make the interstellar portal used in the same plane, Lin Ze had always thought that the Moon Elf was the El who accidentally broke into this plane, but it seemed that it just happened that the text was the same.

"Let's go~ There's nothing I'm looking for here", Lin Ze said tastelessly.

"But the bad guy, I'...... Hmm~" The girl was suddenly covered by the female elf.

"Since there's nothing, let's go, it's dark and stuffy here~" The female elf quietly squeezed her eyes at the girl, and hurriedly said.

Leia took a deep look at the azure arch and turned to follow the others, and the room fell dark again......

I don't know how long it took, but suddenly a red light lit up in the silent darkness, and the light became brighter and brighter, and the entire arch was completely exposed in the red light.

"My lord~ this is what we are trying so hard to find?"

"Give the order to go down, let them do it", the black-robed man waved his hand slightly, and stayed alone in this room where the arch was placed, and after the entourage retreated, she twitched her nose slightly, and walked back and forth near the arch silently, the movement was so fast, she had already come, how did you get in? The black-robed man looked down at the crystal hanging from his waist, no! You didn't go to the exchange office to get this thing, and you didn't even inquire about it, so there is only one possibility left - the same source of energy, you already have the crystal energy source technology of the Moon Elf, otherwise you can't activate any equipment in the Moon Elf Ruins, ha, it's really getting more and more interesting!

……

In a small valley that didn't even have an official name, a simple little camp had been built unconsciously, a simple fence surrounded by wooden stakes, a path isolated by lush low shrubs, and a few tall tree houses, which at first glance looked like a camp just built by a wandering tribe, but inside the largest treehouse, there was a passage directly under the ground cover that led directly to the underground world.

After Lin Ze and his party drilled out of the soil from the outside of the ruins of the upper layer of the sister city, they came directly to the small camp that the snake girl Siqin was responsible for building.

For the snake girls of the two tribes of Wuyue and Yunyue, who have been living underground for so many years, the long-lost sunshine and blue sky make them excited, plus Lin Ze suddenly decided to block the two underground passages of Jing'anbo this time, this news made them cheer even more, which also means that there is no need to stay too many clansmen in Jing'anbo underground, as long as they change people regularly to go on duty, they can enjoy the breeze and sunshine more.

"Your decision is quite timely, this great lord has always been worried about the pair of dark elf father and daughter who left and the dwarf, afraid that they will leak out the great changes in Jing'anbo and even the newly discovered underground spring one day, after all, we can't always be here to be prepared, when the emergency comes, we can't rush to the rescue in a short time", the female elf agreed with Lin Ze's decision very much.

"You're not going to do business underground, it's better to plug it, I can see that the underground spring is important to you, and that's all you need," said Ella, sitting on a thick branch, her legs flicking in mid-air.

The fifth-order Wuhua Spring is indeed very important, Lin Ze was a little depressed in his heart, that's all, wait for him to go back and hurry up to make something, improve his spiritual power, and with the help of Wuhua Spring, he will be able to enter the fourth-order high level, but it also ends here, it is true that Wuhua Spring contains rare substances, but the function of converting rare substances into life energy that can promote his own evolution is limited, and it is difficult to have a second effect after using it once.

Especially in the current situation, Lin Ze didn't know what to do next, the Moon Elf's so-called path to heaven was confirmed to be only an interstellar teleportation technology in the same plane, at most changing planets, and he couldn't send himself back to the plane where the cosmic civilization was located, could he really only slowly improve and wait for himself to enter the sixth order?

"That interstellar portal may not be the kind of mature technology we use, if you look at the level of those moon elves' legacy technology, that interstellar portal will be very reluctant to use", Iriel's voice sounded, "However, I still recommend using the portal, because at the moment this planet has reached its limit, the fifth-order Wuhua Spring is probably already the best quality product here, it is difficult for better things to appear, not to mention, the research environment here is extremely poor, and it is still at the lowest level of energy utilization, If you stay here, you don't know how long it will take to enter the Sixth Order. ”

"What about the past, the Moon Elf's technology has been confirmed to be only the fourth order, and it also has no ability to teleport on the plane."

"At least one thing, the Moon Elves have a background, they are a fourth-order civilization, as long as they have a research direction, it is definitely much more efficient than improving the natives here who have no research foundation, and the time saved will even be calculated in a hundred years or a thousand years."

"But you also said that this interstellar portal is a product of immature technology, God knows if there will be something missing in the body after teleportation, or it may be directly stagnant in the void and decomposed into various primitive source elements."

"The road of evolution, how difficult it is, a few hundred more years of delay, it is very likely that the next advance will be hopeless, and eventually it will turn into nothingness, our It civilization has a large population, but there are a few who can evolve all the way, in the words of your hometown, sailing against the current, if you don't advance, you will retreat, this world is hopeless, you can judge the conclusion from the level of the cultivators on this planet, and there will be a lot of hope for changing the environment at will, so I still insist on taking a risk."

Lin Ze leaned weakly on the trunk of the tree house beside him, he also knew what Irel said, if you are poor, you will change, and if you change, you will understand, but~ Hey!

"Bad guy~ Come here, this woman has made a major discovery~ A major discovery! There's a strange-looking fruit here, so let's see if you can eat it. ”
