Simon returned to Sailun with Neil, but unexpectedly, Maeve also came here with Eva.

"What did you bring her for?" Simon looked at Maeve in surprise.

"Oliver has transformed the disposable black hole shell making machine into a permanent one, I don't know if the fleet will use it, so I will bring it for everyone to see!" Eva said excitedly.

"I think it's fake to open everyone's eyes, it's true that you want to visit the pirate planet, right?" Simon looked at Eva suspiciously.

"Hey, hey, hey...... Found out? Uncle Simon, you're too unrighteous, and you're here yourself! How do you know I'm not going to help you? Eva grumbled.

"Black hole cannonballs? That's a good thing! Our fleet is also decompiling those makers, but it's only a one-time one, and if you can use it many times, it will be a great help! Hawke heard their conversation and expressed his interest.

Not only was he very interested, but he also called Drake.

Drake is the second-in-command of the fleet who is good at technology, and he is responsible for the technical reform of the fleet in peacetime.

"Dad......" Neil saw that his father was closer than he saw himself when he saw the new technology, and he regretted that he and Simon came back.

"Neil? You stinky boy! Let's work on this new device with Dad! Hawke was very happy to see Neil, but he didn't know how to express it, so he forced him to study it with him.

"You, when you can't see your son, you shouted to the heavens and the earth, but now you see it, and you love to ignore it! Is it the son who is important or the black hole cannonball that is important! Simon couldn't wait to go up and beat Hawke, this father really didn't have any consciousness at all.

"Okay, okay, let's talk about the black hole shell tomorrow! Celebrate my Neil's return today! Then welcome Eva, Maeve, and Simon from afar! Hawke happily announced.

He was really quite happy, since his son had an awkward relationship with him and ran away from home, Hawke felt that his world seemed to be at war, and there was nothing else to do, and he was in a mess all day long.

He didn't know what Simon and Neil were talking about, anyway, as long as this kid was willing to come back to his side, it was better than anything.

Since Simon and the others came quite suddenly, they didn't prepare anything.

Hawke took them to the cabin of his battleship and held a simple welcome ceremony.

"Neil, you...... What about playing music? Hawke didn't know what to say to Neil, so he awkwardly found a topic that he didn't think was too embarrassing.

"Hmm......" Neil nodded.

“……”

There was silence between father and son again.

It's not at all like the chatter and back-and-forth between Neil and Simon after they met.

"Neal is amazing! The platform for us to track down a case was done by him! Although we still couldn't find out the final flow of Starlight Coins, he provided us with detailed customer information for us to trace! ”

Simon saw that the atmosphere between the two fathers and sons was so awkward, and hurriedly relieved the two of them.

"Yes, that's good!"

However, after these two brief summative compliments, the father and son fell silent again.

"Neil, go talk to Eva......"

Simon saw that the two of them really had nothing to say, so he took Neil away.

"If you say something soft, you'll die?" Simon glanced at Hawke with disdain.

"Then that kid has to be soft first! I'm his father! Hawke said unconvinced.

"If you want to ease the relationship, one party must let go of the so-called dignity first! Otherwise, you two will just freeze like this......" Simon gave him a blank look and went to Eva's side as well.

Hawke saw that if he continued like this, he couldn't even handle his son, let alone face, and even the position of his battleship station commander would have to be questioned.

"Ahem...... Hawke took the bottle and came to Neil's side, "Neil, what are you talking about?" ”

"You don't understand, why are you asking so much?"

In fact, Neil didn't want to talk to his father like this, but when the words came to his lips, somehow, they turned into a tone with the smell of gunpowder.

'It's okay, don't be angry!' I haven't seen it for so many years, and I definitely don't know how to get along with myself anymore, so I don't get angry! Hawke still had a stiff smile on his face, silently thinking in his heart.

"Tell me about it, and I'll probably understand."

"You know, how much music does to boost morale? Do you know that special sounds can also be used as weapons? You know ......" Neil asked Hawke a bunch of questions at once, questions he had never heard before.

"Tone ...... Music? How much more can you do? Hawke looked at Neil in surprise.

He has always believed that music is just a hobby for a group of children who are not doing their jobs, and they can only indulge in it and cannot extricate themselves.

He hadn't thought about the questions Neil had asked, and he had never studied what music could do for people......

"Look, I'll just say, I can't communicate with you......" Neil said with a shrug, disdainful.

"No, no, no, tell me how music can be used as a weapon?" Of that bunch of questions, Hawke was most interested in this one.

If music can be used as a weapon, then they have a magic weapon to sneak up on the victory, and they can do it without ammo, so why not?

"Hmm......" Neil saw that Hawke's eyes were full of curiosity, and he knew that his father was not asking for a topic, but he really wanted to know how to use music as a weapon.

So Neil told Hawke about his experiments......

To be precise, the most influential is not music, but sound, and high-frequency sound stimulates the brains of various species, thus influencing their thinking.

However, as long as the sound is controlled to a specific frequency, especially the targeted frequency, the person who hears the sound can make the person who hears the sound seem to be disturbed by the mind, causing confusion in the brain, so that they do not know what they are doing.

Hawke listened to Neil talk about his place, and was relieved that he finally had the feeling that my son had grown up.

He even felt that if he had really imprisoned him by his side and forced him to inherit his mantle, Sailun Star might have fallen into the hands of others by now.

"Actually, I've also experimented with lizardmen's sensitivity to sound, and they can't stand high-frequency sounds, they can't stand low-frequency sounds, especially iguanas! When they hear low-frequency sounds, they are in agony, and some even vomit blood! ”

Neil's research really gave Simon a great inspiration, if it is really as Neil said, then attacking the Shadow Brotherhood will be much easier!
