"Could it be the Transformation Plan of the Shield Legion?" Excellence had a guess in his heart, and carefully recalled that among the things that Lily had come into contact with in the past few days, it was most likely that plan.

"I suddenly realized that the concept I had been sticking to was not entirely correct...... "Lily's voice was a little low, and she seemed to be a little suspicious of life!

Anyone who finds this situation will have this kind of thought, Excellence understands it very well, and it can be regarded as understanding, Lily just didn't figure it out for a while, so it slowly asked:

"Can you tell me about it?"

"Nothing bad to say...... I have always been the latest and strongest pursuit of technology, never considered the cost problem, the best effort to make on the cost problem is only, to control the cost within a reasonable range, never want to reduce the cost to the minimum!"

"Isn't this normal? You're best at the latest technology, and cost reduction isn't what you're good at, so why bother?" said Excellence.

"I've always thought so too!" Lily showed a slightly self-deprecating smile on her face: "But after seeing the transformation plan of the Shield Legion again, I found that I was wrong! With the same effect, the plan of the Shield Legion is much lower than my plan, and the cost is much lower!"

"That doesn't mean anything! Maybe it's a different way of thinking?"

"I thought so at first, but with in-depth analysis, I found that the plan of the Shield Legion actually contains a higher level of technology......"

After ...... silence for a moment, Excellence spoke again: "Maybe this is the 'Great Dao to Jane'!"

"The road to simplicity?...... The road is simple!" Lily kept repeating this sentence, and then slowly regained that confident smile on her face!

"You're right! The principle behind the simplest things is often more complex! It's easy to create a new weapon, but it's the hardest thing to simplify it when you're powerful!"

"I'm glad you can figure it out so quickly, pack up and go back early! Your fleet still needs your command!" Seeing Lily's smile, Excellence knows... She's fine!

"Wait!" Lily stopped him just as he was about to leave.

"What's the matter?"

"You can find someone to take command of my fleet again!I think the lab is my place, and managing the fleet is a waste of time!" Lily pleaded.

"No!" Excellence refused the request without hesitation, "Any invention and creation can't be a castle in the air, your main research direction now is the corps-level attack and defense system."

These things are for the fleet legions, and if you don't fight alongside them, how can you know what they need, and if you create something that suits them?"

“...... What you said seems to have a point!" After thinking about it for a while, Lily felt that there was something wrong with the words of excellence, but she couldn't find a rebuttal.

"Of course it makes sense! That's it, quickly adjust yourself, and then return to the team! The demons have not acted in the past two days, and there must be something brewing!"

There are still a lot of things to do, but there is not much time to ink here.

These two days have only made the Demon Slayer Legion familiar with all aspects of the Rock Fortress, and can accurately and quickly use the various defensive attack systems of the fortress.

Other things, such as replenishing war materiel, have not yet begun to prepare, and the Rock Fortress is not yet fully prepared for war!

As soon as he returned to the fortress is control center, Xu Lin looked for him.

"The statistics have been completed, and the materials that need to be replenished and exchanged have been listed, Marshal, you can go and communicate with the Shield Legion!" said Xu Lin as he passed a long list to the control center of the fortress.

"I know, I'll go right away!" Excellence immediately agreed, this is the most important preparation for the Demon Slayer Legion at the moment, and Excellence can't afford to delay.

The so-called war materials, the most important thing is naturally not energy, the eternal furnace of any warship can output full power for decades, and there is no energy shortage at all.

The largest amount of materials is actually the various spare parts and spare modules of the battleship, as well as the various spare functional modules used in the fortress, which are the basis of various attack and defense systems of the legion and the fortress, and once the war starts, it is also the fastest damage, and there must be enough spare parts.

Among them, the spare module for the fortress has been prepared for a long time, and there is no need for excellent replenishment, but the parts and modules for the battleship need to be deployed by the Demon Slayer Legion itself.

Of course, there are a lot of reserves in the Rock Fortress, but they are all used by the last legion that presided over the fortress, and the warships of each legion are different, and the offensive and defensive means are different, so the parts and modules that need to be used are also different.

It turns out that some of the reserves of the fortress can be used by the Demon Slayer Legion, and some need to be replaced, which needs to be completed as soon as possible, otherwise the strength of the legion may decline if the continuous battle continues.

Of course, for the Demon Slayer Legion, all kinds of raw materials are also materials that need to be stockpiled in large quantities, after all, the Demon Slayer Legion has many exclusive means, and the modules required by these means can only be self-made, and the Demon Slayer Legion is not short of manpower, only raw materials!

When Excellence found the Solid Shield Legion with the list, he didn't see the Marshal of the Solid Shield, but only Liu Yuan, the deputy commander of the Solid Shield Legion in charge of logistics!

When he first saw this Liu Yuan, his attitude was quite cold, and he thought that this Liu Yuan would make trouble for them, and he was quite worried in his heart.

But the result was not like this, Liu Yuan did not discount his request at all, nor did he deliberately delay things like that, it was completely businesslike, and he quickly deployed the materials.

Excellence thought about it for a long time and didn't understand why this happened, after returning to the Rock Fortress, she found that Lily had returned to her fleet, so she was happy, and put this question behind her, anyway, the matter was done, and there was no loss, what do you want to do so much?

In the midst of the busyness, the demons attacked again, and this time the power used was even more powerful, with the strength of six legions, and it took three days to prepare, and the preparation was quite sufficient.

When he saw that there were six legions of demons attacking, a question arose in his heart: "Can the Shield Legion still withstand this time, will there be a chance to participate in the battle?"

In the end, it turned out that Excellence was still too worried, and the Shield Legion was worthy of his name as the Iron Wall of the Federation, and even withstood the onslaught of six legions alive, and did not let three fortresses participate in the battle.

Of course, quantitative changes can often cause qualitative changes, and the shield wall of the Shield Legion is indeed very strong, but there is still a limit, and the strength of the six legions can just break this limit!

Therefore, the Shield Legion still used the support of the three fortresses, just the support of the strength, which directly doubled the strength of the Shield Legion, and once again had an overwhelming advantage, after two hours of fighting, the six demon legions finally returned in vain!
