Following the route in his memory, Tang Xiaofeng saw the escape pod again.

From the outside, it looks like an enlarged metal rugby, only more than ten meters long, with a diameter of only a few meters in the middle, and the whole reflects a silver luster.

He'd experienced it firsthand, and the interior was much bigger than it looked.

The Luojia civilization belongs to the twelfth level of civilization, including warships, and has made extensive use of space folding and space expansion technology.

Standing outside the escape cabin, Tang Xiaofeng contacted Liuli, and on the metal shell of the escape cabin, a portal like water waves soon formed.

He entered the escape pod and, following Ruri's instructions, placed the energy hedron in a groove on a platform.

A rapid "tick" sounded, and Tang Xiaofeng vaguely felt that in a place where he couldn't see, the escape cabin was undergoing incomprehensible changes.

In about a quarter of an hour, the dripping sound died down, everything was still, and the energy hedron inside the groove became transparent.

"Report to the captain! After the self-test of the main control optical brain is completed, the energy reserve is seriously insufficient, and it is impossible to break away from gravity, and it is impossible to connect with the battleship for long-distance jumping, so it is recommended to activate the engineering robot and build an energy collection station. ”

Tang Xiaofeng was stunned for a moment, frowned and repeated in a low voice: "Engineering robots? Energy harvesting stations? Then he asked, "Will anyone find out?" ”

Although he received some knowledge of the Luojia people, he only knew a small part of it.

"Captain rest assured, engineering robots have extremely strong anti-reconnaissance capabilities, and civilizations below level 10 do not have the ability to capture!" Ruri replied, "And the energy harvesting station is built deep underground, which is difficult to detect with the current civilization level of the earth. ”

Tang Xiaofeng felt a little relieved, he heard Liuli mention the civilization level twice, he became curious, and asked about the civilization level of the earth, and the answer he got made him feel depressed.

According to the Xinghai Civilization Level Promotion Criteria, the Earth is currently in the third. Level civilization, only by mastering space transition technology, can the earth be promoted to a level 4 civilization.

Next, under the guidance of Liuli, Tang Xiaofeng visited the entire escape cabin and saw many cabins, and he finally understood that the interior of the escape cabin was far more complicated than he imagined.

As a higher civilization, after the civilization process of Luojia people fell into a bottleneck, everyone inevitably paid attention to enjoyment, so even if it was just an escape pod, they still had all the living and entertainment facilities.

After wandering around for a while, Tang Xiaofeng gradually lost interest, no matter how good things were, he was the only one, once the excitement passed, he didn't feel much fun.

He stood outside the cabin where the Star Sea Secret Treasure was stored, and without waiting for the hatch to open, he asked Liuli, "What is the Star Sea Secret Treasure?" ”

Liuli was silent for a moment, and then a voice came: "The sea of stars is infinite, the secret treasure is the general name of some strange things, the legend says that these strange things are the products of the will of the universe, the Luojia civilization has fallen into a bottleneck, so it wants to continue to promote the process of civilization by cracking the secret treasure of the sea of stars." ”

"It's the same as not saying it!"

Tang Xiaofeng muttered quietly, and when the hatch opened, he couldn't wait to look inside, but the next moment he was stunned in place, and what he saw in front of him was a round ball suspended in the air, about two meters in diameter, emitting orange-red light, like a burning star.

"This is the Secret Treasure of the Star Sea?" After coming back to his senses, Tang Xiaofeng asked, "What is it for?" ”

"Deal! Barter with higher civilizations! Ruri quickly replied.

"Deal? What do you mean? Is this just a trading platform? Tang Xiaofeng was a little puzzled and continued to ask.

"Of course, as long as any civilization obtains the secret treasure of the Star Sea, it is equivalent to making its own civilization come into contact with a higher civilization in advance, and get what it needs for the development of its own civilization."

Tang Xiaofeng pondered for a moment and understood in his heart, this was a thing that could be traded across space, but he couldn't think of anything on the earth that was lacking in advanced civilizations.

When he asked Liuli, Liuli sneered and said: "No civilization is perfect, there are always things they lack, just like the Luojia civilization, which has almost reached the peak of scientific and technological civilization, is only one step away from entering the sky of the gods and becoming an eternal civilization, but there are still many things missing, such as the most ordinary plants, water, and even soil and air on your earth, which are all lacking in the Luojia civilization." ”

"How so?" Tang Xiaofeng listened and blurted out that the things listed by Liuli were the most common.

"There is nothing strange that the rise of scientific and technological civilization will inevitably be accompanied by devastating development, and before finding infinite energy, the first thing to destroy is its own ecological environment."

Tang Xiaofeng thought about it, and soon fully understood, and he asked again: "Then how to make a transaction?" ”

"First imprint the treasure with spiritual power, become the owner of the treasure, and then put the traded items into the treasure."

After hearing this, Tang Xiaofeng became excited, this Star Sea Secret Treasure was actually similar to the plane transactions in many system texts, and he couldn't wait to try it.

"Ruri, send me out immediately, I'm going to collect something! Pull me back in ten minutes! ”

"Okay, Captain!"

A burst of blue light flashed, and Tang Xiaofeng appeared on the surface.

This is the ultra-short-distance material delivery function of the escape pod, which requires only a small amount of standard energy to activate.

Tang Xiaofeng looked up at the sky, the moonlight was bright, and the stars dotted the sky, these scenes could not be seen at all in the urban area with heavy light pollution.

Taking a deep breath, he took action, folded more than ten branches in a row, held them in his hands, dug some soil from the ground and wrapped them in clothes, and the time to do these things was about the same, and another burst of blue light flashed, and he returned to the escape pod again.

The so-called imprinting with spiritual power is to separate a trace of one's own spiritual power and leave it on the things that need to be imprinted, under the guidance of Liuli, Tang Xiaofeng finally completed it after several attempts.

After that, everything was much simpler, after leaving a spiritual imprint, he was already able to roughly grasp the secret treasure, and he could directly put it into it if he also wrapped it around the object with spiritual power.

On his first attempt, he marked the 10 branches as ranging from 1 unit of standard energy to 10 units of standard energy, and bundled the remaining branches with the soil for auction.

Since it is marked with spiritual power, there is no problem such as language barrier, after doing this, with Tang Xiaofeng's spiritual power after development, he can't help but feel tired, and using the Star Sea Secret Treasure itself is to consume spiritual power.

Closing his eyes and resting for a while, he used his mental power from time to time to probe the situation of his goods, which were originally just ordinary things, and he didn't expect to be able to sell them soon, but he couldn't help but stare at them, but the results of his second inspection surprised him.

All the branches were sold, and where he had placed them, there were many more energy crystals, but of different sizes and shapes.

He looked back at the place where the twigs and soil had been placed, and as he thought, the things had been sold, but there was a rectangular pale pink box there.

"What is this?" Tang Xiaofeng thought secretly, his spiritual power was recovered, and he took out the energy spar and the box together.
