After another explanation from Dong Fang, Chu Nan finally understood the whole story.

It turned out that in the two years since Chunan disappeared, nuoyantem chamber of Commerce was not idle at all. Alcatel brought back the judgment and some data of portal left by Chunan before Chunan disappeared to the chamber of Commerce. Nuoyantem chamber of Commerce conducted targeted research and made a great breakthrough in the research of portal.

They have even been able to generate portals out of thin air through the combat simulation experiments between enterprise warships and star class fighters.

However, they have not fully understood the generation mechanism of these portals, and the occasionally generated portals are extremely unstable and cannot be successfully used for passage every time.

However, nuoyantem chamber of Commerce has still greatly improved its understanding of the portal. The most obvious example is that it can clearly grasp the special energy fluctuation in the special space of the portal and follow the path to explore in a certain range.

Two years ago, the portal that Chunan passed through in aika R27 did not completely disappear. Nuoyantem chamber of Commerce invested a lot of human and material resources in it and maintained the existence of this portal through a large amount of energy supplement.

And with their in-depth research on the portal, the energy demand to maintain the portal has been gradually reduced.

At the same time, the nuoyantum chamber of Commerce has been studying the coordinates left by Chu Nan in the dark star domain of the portal section.

Although the portal channel over there collapsed due to the "ignition" of Chunan, it left some traces of energy fluctuation to be captured. Through research, Noam chamber of Commerce has basically mastered the method of opening the portal, and it is basically determined that the other end is located in the star region near FADILA through the energy fluctuation trajectory inside the portal.

This time, the nuoyantem chamber of Commerce sent the fleet commanded by Captain Klein to jump into the dark star domain through the portal located in the eKa R27 star domain, and then forcibly open the portal through the portal sign left by Chunan to explore the other end of the portal.

But what surprised them was that after the fleet passed through the portal, the energy shock caused the portal to collapse and disappear, and they also collided head-on with the fleet of the erewarna military treaty alliance stationed on FADILA, resulting in a fierce battle immediately.

This is an out and out encounter. Both sides did not expect to meet the enemy here before the fight. Relatively speaking, the erewarner military treaty alliance is stationed here. Naturally, it has a better understanding of the environment here and can get more logistical support. Naturally, the Noam chamber of Commerce fleet is in a disadvantageous state.

If Chu Nan didn't appear suddenly, they would have lost the exit way of the portal, and basically the whole army would be destroyed.

After hearing this, Chu Nan nodded and roughly understood what was going on, but he still had a very important problem.

"So it's normal for uncle Klein to lead the fleet here, but why are you here?" Chu Nan looked at Dong Fang strangely.

That's what he doesn't understand. How did this guy come here with the fleet of the noahtham chamber of Commerce? And with people from Ceres security?

"I'm here to join the fun, ha......" Dong Fang laughed and answered casually.

Of course, Chunan didn't believe his nonsense and turned to captain Klein.

Captain Klein glanced at Dong Fang and smiled, "After receiving the news, Mr. Dong said to the chamber of commerce that Mr. Chu, you lost the news after passing through this portal, so he wanted to come and find your whereabouts. After confirming his relationship with you, the chamber of Commerce agreed to his request. After all... Thales security company is also an excellent combat force of your Earth Federation, and we can't refuse this powerful comrade in arms to join us."

Chu Nan looked at Dong Fang and felt a warm current in his heart.

This guy, knowing that there are all kinds of dangers in this operation, still forced to follow. Obviously, he wanted to determine the whereabouts or life of Chu Nan.

This friendship has transcended life and death.

Dong Fang was a little uncomfortable by Chu Nan, so he didn't turn his head and muttered, "Xiao Xi asked me. She said if she had a chance to know your whereabouts, she must tell her. Anyway, I just wanted to come here to find out the news, so I followed. Besides, it's good for me to follow Noam chamber of Commerce, so I'll be in the company... Hey! Why do you beat me?"

Chu Nan hit Dong Fang on the chest, smiled at him and shook his head.

"Come on, you're not fit to be like a woman like this. I just know what's going on."

Dong Fang was stunned, smiled at Chu Nan, and suddenly stretched out his arms to Chu Nan.

"Welcome back, brother."

Chu Nan smiled and reached out to hug him again.

After the two separated, Chu Nan put away his smile, turned to captain Klein and asked, "the evacuation plan you began to prepare is to jump back to the dark star field through the portal, right?"

"Yes." Captain Klein nodded and then said with a bitter smile, "but after our fleet jumped out of the portal, the portal disappeared. Now it's impossible to jump back like this."

"Don't worry, Captain Klein. Since Chu Nan asks so, it proves that he has a way. Am I right, Chu Nan?" Dong Fang patted captain Klein on the shoulder and looked at Chu Nan.

"Yes." Chu Nan looked around and asked captain Klein, "how much energy is left for this enterprise class warship?"

Captain Klein looked at Chunan suspiciously.

In this case, he said there was a way?

Thinking of all kinds of rumors about Chu Nan circulated within the chamber of Commerce, Captain Klein hesitated and replied honestly: "there are still 37%."

"37%..."

Chu Nan quickly calculated in his mind and nodded.

"That's enough."

Chu Nan beckoned to captain Klein and Dong Fang and went to the bridge Command Office of the enterprise warship with them. By the way, he found some combatants in the warship and listed the data he had just calculated.

"... later, you will attack the high concentration particle beam at the coordinates I said. Remember, the frequency of the particle beam must be adjusted to the highest, and the jump engine must be started synchronously to inject the particle beam with the energy output. Eh... Before you came, did the chamber of Commerce mention to you the relevant data of opening the portal?"

Dong Fang looked at captain Klein, who nodded: "as mentioned, our visit was originally an experiment, and we collected data by the way."

"That's all."

Chu Nan explained his idea in more detail, and finally left a sentence: "I will tell you all the temporary data in a moment, and you can cooperate with me as much as possible."

Dong Fang looked at Chu Nan strangely.

This boy, does he know who he is facing now?

These are the elites sent by nuoyantem chamber of Commerce. He actually looks like dragging and talking to them in an ordered tone?

However, to his surprise, Captain Klein just thought about it and nodded his head.

"OK, we will try our best to cooperate with you."

Dong Fang was immediately dumbfounded.
