After leaving this spacious and calm area in the middle, there was no way to deploy dozens of fleets in other places, and these demon fleets did not dare to touch those dangerous areas.

However, this also created a large number of sneak attack opportunities for the demons, and after adopting the tactics of small-scale sneak attacks in separate battles, the strength of the Demon Shadow Legion's fleet has significantly improved.

The endless sneak attacks made them annoyed, but fortunately, Hu Xue was in a tight formation, restrained his impulses at the critical moment, and held the formation tightly and never pursued, but there was no danger.

Especially after a few Golden Immortals and Excellence met, the Demon Shadow Legion immediately retreated with interest, making the formation of the second half of Zhuo and them a lot smoother.

It wasn't until after leaving the nebula that Excellence felt a relief in his heart, and the oppressive feeling finally disappeared.

Excellence knew that this time they were able to come out so smoothly, thanks to the restraint of both sides, and there were not too many losses, so the battle did not completely intensify.

The real loss is only the Revival Society, but no one cares about this, in the eyes of the demons, they are just a pawn that can be used, and it doesn't matter if they lose.

As for the fleets that were killed by Hu Xue, the Demon Shadow Legion also didn't care much, this was originally a fleet consortium, and the sense of identity between them was not strong, and the Demon Shadow Legion had sufficient reserves, so they didn't care about this loss.

Overall, the mission was completed quite smoothly, and if Xu Lin and his three teams and nine fleets could return safely, it could even be called a success!

After returning to the station, these ten fleets were handed over to Ziyun and Lily, and they had just experienced a big battle and discovered many minor problems.

Although these small problems did not affect the strength of the dual-core fleet much, they could also open up the minds of Ziyun and the others to further improve the structure of the dual-core fleet, and Excellence also hoped that it could be even more perfect.

After more than ten days, Xu Lin finally brought back the three fleets completely, and then the other six fleets also returned one after another.

"How is the fleet performing this time?" Excellence asked Xu Lin directly, "Did you find anything that needs to be improved?"

"If you really want to evaluate, there is only one - reborn! The dual-core fleet is completely different from before, especially when facing a strong enemy!"

"Oh, then tell me about your results!" Excellence was not as high as Xu Lin's evaluation, so he was interested.

"When we first ambushed the three demon patrol fleets, we had the advantage, and the battle was completely devastating, I only felt that the fleet was stronger than before!

But later, he was ambushed and besieged by nine fleets, and the strength of the dual-core fleet was truly revealed, and one against two could still have the upper hand.

In the end, we also killed three fleets, but unfortunately the other six fleets ran away, we didn't dare to stay any longer, so we came back first!" Speaking of this, Xu Lin still had a feeling of unfinished, such a hearty battle was not easy to encounter.

"Is it so strong?" was still a little skeptical about the excellence of this record, but suddenly it occurred to me that the demon clan had transferred to ambush Xu Lin's fleet, and it was definitely impossible to compare with the fleet of the Demon Shadow Legion, so this record was also normal.

"If you strengthen your training, you will only be stronger!" Xu Lin replied affirmatively, this battle really made him feel the surging feeling of blood that he had not seen for a long time.

"As long as there is enough tacit understanding between the two core immortal ships of the fleet, there can be no flaws in the battle, especially when facing multiple enemies, there is basically no worry about losing one or the other. Xu Lin explained again.

"These are the good things about the dual-core fleet, after this combat test, what do you think is still in the fleet, and what needs to be improved?" Excellence continued.

"There are a lot of problems, but they are all small problems, which do not affect the overall situation, and it is very simple to improve, as for the improvement, I really found one!"

"What is it?"

"The current dual-core fleet structure has brought the strength of the fleet to the extreme, but during the battle, I found that the linkage between the fleets has decreased!

When a small number of fleets cooperate with each other, this lack of strength has no effect, but if a fleet is formed, it will seriously waste the combat effectiveness of the fleet!

The dual-core transformation will increase the overall strength of the fleet by at least fifty percent, but if the entire legion completes the transformation, I estimate that the increase will not exceed two percent, and the waste of power is huge!"

Xu Lin explained his speculation, as the second best commander in the Demon Slayer Legion, Xu Lin knew quite well about the Demon Slayer Legion, and had directly commanded the Legion more than once in battle.

So he was able to keenly find the shortcomings, and although Hu Xue was more talented, he hadn't really commanded the legion after all, so he didn't see this shortcoming!

Hearing Xu Lin's story, Ziyun and Lily, who were sorting out the battle records, also put down their work and shifted their attention.

"Xu Lin, what you said is true, is the overall improvement of the legion really so small?"

"I'm pretty sure that I don't dare to say that I know the entire legion well, at least I know my own fleet very thoroughly, and it's impossible for any anomalies in the fleet to escape my eyes!" Xu Lin assured.

"Arrange the test immediately, if this is really the case, the structure of the fleet will have to be adjusted a lot!" Xu Lin was so sure that Ziyun had to pay attention to it.

So the three fleets that Xu Lin brought back, the ten fleets that had experienced a major war, and the dozen or so fleets that had just completed the change, were quickly assembled.

Ziyun and the others began to urgently design the fourth round of tests - the Legion Basic Combat Effectiveness Test!

Such a big movement naturally couldn't hide from Marshal Muxin, and Marshal Muxin, who was visiting the transformation of the fleet, was immediately attracted to it.

"Excellence, what's going on, how did you make such a big move?" asked Marshal Muxin.

"It's not a big deal, it's just that Xu Lin brought back a bad discovery, the growth of the strength of the fleet is not proportional to the growth of the strength of the legion, and when the legion is fighting, there is a serious waste of the strength of the fleet......"

Excellence briefly introduced the whole story, and then suggested: "Marshal, you should also inform the Shepherd Legion to suspend the fleet transformation! If the structure of the fleet is too large, it will be a waste to renovate it!"

"Is the strength of the Legion not proportionate, is the fleet's combat power seriously wasted, has it affected the original combat effectiveness of the Legion?......" Marshal Mu Xin asked with a frown.

"The fleet's combat effectiveness is seriously wasted!, but fortunately, the combat effectiveness of the legion is also increasing, but this increase is less than one-third of the growth of the fleet's strength!" replied Zhuo Zhuo.

Speaking of which, this is actually not bad news, after all, the strength of the legion has still improved, but it is just a little short of expectations!
