The appearance of Lu Yuan in the Sky City has indeed done no harm to the interests of all mankind.

But obviously... it will strengthen Unkai City.

They can't get some private information at all!

Yunhai City keeps getting stronger, they are afraid!

They stared at the flying city on the screen and observed it several times.

"They will be annihilated by the Rat Men soon." Many people thought secretly in their hearts, but did not dare to express it.

What is even more worrying is that Yunhai City already has level three experts, and other cities also have level two experts.

They...have nothing.

"Everyone, it doesn't matter! As long as everyone cancels the safe zone, we can get back the lost fifty years."

…

"Why was the Pathfinding Project terminated?" Digdit, the supreme leader of the ninth branch in Zero Wave City, asked a scientist.

The expert quickly said: "With the passage of time, the external monsters are strengthening much faster than us humans."

"Someone who once had the ability to dream had something happen to him in his dream."

"In addition, the chance of finding it was too low, so the path-finding plan was terminated midway."

Digdit sighed. There was no point in contacting Lu Yuan now. After all, the establishment of friendship cannot be completed overnight.

Fortunately, humanity's 18th civilization, far away in the world, should not ruin his plan.

He has already controlled the leaders of several cities through his "control" ability.

It is unrealistic to control everyone, but as long as a few are controlled, the [Demon] crusade plan can be steadily advanced.

However, there are also some cities that are more cautious and the super power transmission function of the liaison device is not turned on, including Yunhai City.

Digdit frowned, thinking about the variables.

…

…

…

After winning a battle, Lu Yuan received an invitation from Shumiba Civilization to discuss major trade matters.

And won the reward of "anti-counterfeiting match".

The so-called one hundred spirit crystals are actually one hundred pieces of low-quality spiritual crystals!

The shiny stones, each about the size of a glass bead, were placed in a small bag and made a tinkling sound.

Apparently, this thing is the standard currency of the Eighth Age.

"Humans are an excellent race and have gained the sincere friendship of our Shumiba civilization. You are welcome to be our guests!" The yellow-clothed mouse king looked like he was in pain and handed the bag containing the spiritual crystals to Lu Yuan.

After a great victory, the opponent's attitude suddenly improved.

Lu Yuan is quite enthusiastic about this matter. Alien civilizations from the eighth era are not common.

"You will definitely be able to get a lot of information from it."

Lu Yuan said a few polite words at first, and then changed the topic: "Let's go back to deal with the injuries and reorganize the city, and then come back after a while."

He must understand the true value of 1 Lingyun!

If you can’t even figure out the exchange rate, you will help count the money after being sold!

"Haha... Please come here. This Mr. Jin Dongliang is very brave. We have good medicine for you as a gift."

"But, can the captured brother be returned to us?"

Since the other party was so cooperative, the human side could only return the captured "blue golden rat", but there was no such thing as a lion opening his mouth.

Next, Lu Yuan rode the "Flying Dragon" insect and took everyone back to the Sky City.

He settled the injured Jin Dongliang, and then praised the immortal giant tortoise for its great achievements.

"Oh, thank you for your hard work. When you go out, you will always encounter accidents like this."

Jin Dongliang laughed: "Fighting for the country is an honorable thing. Why do you have to work so hard?"

Lu Yuan was stunned.

Yes, this is not his civilization alone. It is normal for everyone to work together.

"Mr. Jin, take good care of your injuries."

A small group of elite scientists were also convened.

As the saying goes, "No fight, no acquaintance." Lu Yuan felt that the probability of war with the "Shu Mi Ba Civilization" was not very high, so there was no need to send too many soldiers. Instead, he called a group of scientists over, and the communication effect might be better.

"These low-quality spiritual crystals are all earned by us."

"Can you study how much energy it contains? Is there any possibility of production here?"

"So much!" The scientists were shocked. This small bag cost a total of 100 yuan!

Even if the quality is "inferior", it is still more than the entire Mandala Empire combined.

"Well, this must be artificially created, otherwise this idealistic energy would not be divided so neatly."

In fact, the green civilization also has a way to make spiritual crystals, but the specific method is a bit expensive and requires the essence of the heart of the poppy tree - now it is difficult to mass-produce these things with only one stump of the poppy tree.

In the past thirty years, mankind has been looking for alternative solutions. Unfortunately, due to limited manpower and material resources, the results of this work are quite limited.

"Spiritual crystal" can significantly speed up the speed of cultivation. Even if it is only "inferior quality", it can speed up the training by more than 50%. It is not a good thing.

Looking at the lively discussion among the people, Lu Yuan said: "Calculate the value of a spirit to save yourself from being like a headless fly."

"Arrange the candidates for diplomacy. We will set off after a while."
