Mu En is sitting in the Batcave filled with various high-tech equipment, making something special.
And Bruce and Selina are in the courtyard, seriously fighting each other.
Of course, there are differences between the two of them. Bruce has learned more and can attack with any weapon he picks up, while Serena doesn't like swords very much, but chooses one of them.
Several fighting methods are connected.
At this time, Bruce's hands were wearing gloves, and he used the cold-faced fury that Moon gave him to attack Serena one after another.
Serena also mastered this fighting skill and kept using her fists to block Bruce's attacks.
"If this is all your attack, you won't be able to defeat me!"
Perhaps because she is a girl, Serena is more flexible than Bruce. Although Bruce's punches are very fast, Serena can easily catch them.
"Really? Then I'm coming!"
Bruce smiled, walking with flexible steps, and the attacks in his hands became faster and more uncertain.
The sudden increase in the frequency of attacks, coupled with the pace of Bruce's feet, made it impossible for Serena to resist as easily as before.
Serena was seen making a defensive posture, using her right arm to block Bruce's fist, and then swung her fist towards Bruce.
Winter~
Faced with Serena's counterattack, Bruce stepped backwards and successfully avoided the fist attack. Then he suddenly turned around and kicked out, blocking Serena's kick.
Bang bang bang...
Alfred, who was watching on the sidelines, applauded. Both Bruce and Serena had made great progress, which was something he, the old butler, never expected.
"Master Bruce, Miss Serena, today's training is over!"
After applauding, Alfred took out a towel and reminded the two of them to stop and rest for a while.
They are only over ten years old and are still in the period of physical development. They cannot yet carry out high-intensity training on these combat skills.
The two of them did not refuse. They took the towel handed by Alfred and wiped the sweat from their foreheads.
"Alfred, is the teacher still in there?" Bruce asked while wiping.
"That's right, Master." Alfred nodded, "Mr. Moon is still inside, he seems to be doing something."
Mu En didn't tell them what to do, but he could see that Mu En was very busy every day, and the instruments and equipment shipped from the Wayne Group were kept on.
No one knew what Mu En was doing, and Mu En didn't tell them anything about being in the Batcave.
"I don't know what the teacher is doing. Maybe the teacher will leave after finishing the work."
Speaking of this, Bruce's mood became obviously depressed. He really didn't want Mu En to leave here.
"Adults always have to leave, and didn't he promise you that he would come back to see you often?"
Serena comforted him. She also had relatively complicated feelings for Mu En. Although she did not regard him as family like Bruce, she also recognized him very much in her heart.
Moreover, now she has received guidance from Mu En and learned many fighting skills, which makes her even more grateful to Mu En.
The Mu En they were talking about was manufacturing amplitude crystals in the Batcave.
The amplitude crystals were enough before, so he didn't make anything extra, but now he plans to make some more. On the one hand, he will strengthen his current equipment, and on the other hand, he will integrate the amplitude crystals into several pieces of equipment, just as a gift.
Give Bruce their gift.
Of course, the manufacturing of amplitude crystals is still not easy. Even with the equipment shipped by Wayne Group, his manufacturing progress has not been much faster.
"Hey~ How about giving them some amplitude crystals that integrate pressure points?"
Basic amplitude crystals are divided into three categories: red copper, silver, and gold, and the difficulty of manufacturing becomes higher and higher as the categories increase. The pressure point is a red copper crystal, and the difficulty of manufacturing is relatively low, which will greatly reduce Mu En's work.
The amount can also allow him to speed up the production of more amplitude crystals.
Of course, in addition to the basic three types of amplitude crystals: red copper, silver, and gold, there are also some more special crystals, including high-end platinum crystals, crystal-like cracked crystals, etc...
However, the technical difficulty of these special crystals is still too high for Mu En. If he wants to make a gold crystal now, it will take a lot of effort.
"These basic crystals are so laborious, so what should we do with the special crystals in the future?"
Mu En, who was making amplitude crystals, fell into deep thought. These basic amplitude crystals were already so complicated. It was hard to imagine how difficult it would be to make crack crystals.
"It seems that the foundry cabin needs to be built as soon as possible."
With the foundry cabin, amplitude crystals, weapons and equipment, and even ammunition supplies can be easily manufactured.
Of course, before he could build a foundry cabin, he had to have a spaceship first.
"I'll go find Howard when I have time. I need to see if my spaceship is ready."
During a moment of random thoughts, a red copper-colored amplitude crystal took shape in his hand.
[Pressure point +120% melee damage]
"Well, let's just fuse it into the dagger."
He planned to give Serena and Bruce each a dagger. The dagger was also one of the easiest weapons to carry, and it was perfect for self-defense.
As for Alfred, the old butler is already old, so it is only appropriate for him to use a pistol.
As time went by, amplitude crystals were born in his hands, and a month later Mu En finally walked out of the Batcave.
"Afu, where are they two?"
Seeing that there was no sign of Bruce and Serena in the study, Mu En looked at Alfred who was sorting documents in the study.
"The young master and Miss Serena are training in the courtyard." Alfred smiled when he saw Mu En walking out of the Bat Cave.
Hand Alfred's commonly used pistol to the other party. This pistol has been fused with a wasp sting that increases the damage of the pistol. The destructive power of the bullets fired has been increased by 220%.
"This is for you, please be careful when using it."
In the courtyard
Bruce and Selina are training. Compared to a month ago, their fighting skills have become cleaner and sharper.
There were constant muffled sounds between the two, and both the frequency of attacks and the changes in attacks had greatly improved.
Bang bang bang...
Mu En smiled and clapped, and the sound attracted their attention.
"Teacher, you're out!"
Bruce looked over in surprise. This was the first time he saw Mu En walk out of the cave in this month.
Serena on the side was also very surprised. She didn't expect Mu En, who had been immersed in that strange cave, to actually come out of it.
"Well, this is a weapon for you two."
After saying that, he placed two daggers with shining cold light on the table in the courtyard.
These two daggers attracted them. Even if they just looked at them from a distance, they could feel how sharp these daggers were.
