In the middle of the night, the third watch was woken up, but Mu Chen did not have a trace of resentment, and rushed to the scientific research institute with the wolf girl.

Today, the scientific research institute is already the most important institution of the Earth Federation, and every project developed here is extremely important, and once successful, it is likely to change the fate of the Earth Federation and even the galaxy.

"Here we are." Lisi greeted her with a smile and reached out to straighten the messy hair on Mu Chen's forehead.

"Where are you in the experiment?" Mu Chen asked.

"Look, you're in a hurry, I'm preparing to conduct a comparative experiment on the defensive power of the magic shield and the energy shield, and the results will be available soon." Liz introduced briefly.

The Gaians' magic shield covers a much larger area, and can even directly wrap a planet, covering a much larger area than the energy shield used by the Earth Federation.

Unable to find the artifact of the Wall of Sighs, Mu Chen could only pin his hopes on the magic shield.

In the laboratory, a small magic array was drawn on the ground, and the artificial spirit stones produced by the Andromeda Galaxy provided energy for the magic array, and soon a bowl-mounted shield with a diameter of tens of meters appeared in front of everyone, while on one side was the shield generator produced by the Earth Federation.

"Defense Comparison Experiment Begins, High-Energy Particle Beam Ready, Countdown ......"

With Lis's command, two beams of particles that continued to output were directed towards the two shields in the laboratory, and the blinding light made everyone barely open their eyes.

The wolf girl gave Mu Chen a pair of sunglasses in time, and she didn't know when she prepared them.

Wearing sunglasses, it was really much more comfortable, Mu Chen smiled lightly at the wolf girl, which can be regarded as expressing gratitude.

But this insignificant action made the wolf girl happy......

Both shields have strong defenses, and the high-energy particle beams have been attacking for 20 minutes, but they have not been able to penetrate them, but the energy consumed by the shields is very different.

The 5 artificial spirit stones on the magic shield barely consumed much, while the energy pool of the energy shield had almost bottomed out, so it can be seen that the continuous defense provided by the magic shield was longer and the consumption would be much smaller.

"The magic of the Gaians is really magical." Mu Chen sighed that the technology that the earthlings were proud of had actually lost in front of magic for a while, which was really surprising.

"I suggest that this kind of magic array that can create magic shields be drawn on all habitable planets of the Earth Federation, so that at least our defense problem will be solved in the event of an invasion by the demon clan." Liz suggested.

"That's right, before we can find a way to quickly destroy the ghosts, we have to try to build a defensive line first." Mu Chen nodded approvingly, "Not only should this kind of magic array be drawn on the major habitable planets in the solar system, but all habitable planets in the galaxy should have such defensive measures. ”

"Then we have to increase the production of artificial spirit stones, although the consumption of magic shields is low, but if you want to defend an entire planet, I am afraid you will have to consume at least 5 to 10 artificial spirit stones every day." Lisi said with a quick calculation.

"That's much more cost-effective than the energy shield, and it's a lot more convenient, if you use the energy shield to create a line of defense, I'm afraid that even if we combine it with the planet's kinetic energy extraction technology, there will be an energy crisis."

The artificial spirit stones produced by the Andromeda Galaxy should become a hot commodity now, Mu Chen immediately decided to expand the production line of 200 artificial spirit stones in the Andromeda Galaxy, produce spirit stones at full capacity, and reserve as much as possible, this thing is likely to be an important strategic material against the ghost clan.

Linglong finally has a sought-after specialty, which is also a good opportunity to advance the technological development of the elemental people.

"Now we have the means of defense, but passive defense can't solve the fundamental problem, Lisi, you have to work harder, see if you can find a way to quickly eliminate the ghost clan, you can't let our warriors take laser guns to fight the ghost clan." Mu Chen said solemnly.

"You know, the weapon design team already has some ideas, but it will take a while to make them." Lisi said with a smile.

"It's good to have ideas, at least it can give me some hope." Mu Chen breathed a sigh of relief.

In fact, many of these ideas are borrowed from the combat experience of the daredevils, after all, they are all first-hand information, which is much stronger than crossing the river by feeling the stones.

It's good news to have the magic circle recreated, but it's still going to be difficult to protect all the habitable planets in the galaxy within a year.

Mu Chen thought for a while, and asked aloud: "Can you use this magic array to wrap the wormhole exit of the Gaia galaxy leading to the galaxy, so that you can install an anti-theft door for the galaxy, which can greatly delay the speed of the ghost clan." ”

Lisi laughed with a "poof": "I really don't know how your brain grows, you can think of this kind of ghost idea." ”

"Did you get a head?" Mu Chen asked with a smile.

"Of course, as long as you adjust the inscription of the magic array slightly, it's not that difficult, I'll arrange it and notify you when it's done." Lisi said with a smile.

The galactic alliance is still speeding up its formation, and the Reaper fleet has long been stationed at the exit of the space wormhole, and it does not dare to relax for a moment.

Mu Chen's security door plan, once successful, can release the Reaper fleet from the mission of garrisoning the exit of the wormhole, and only need to leave some drones and reconnaissance satellites there to keep an eye on.

……

While everyone was busy and nervous, Richard was also busy with his life events.

This guy is getting married, Mu Chen is happy for him in his heart, but being arrested as a best man makes him a little unbearable.

"I think this dress looks good, huh? There's no need to change it again, right? Mu Chen said helplessly.

Richard has been taking Mu Chen to soak in this dress shop for a day, trying on countless dresses, but he has never decided, and Mu Chen's rare vacation time is in vain.

"It's a big life event, so you can't be sloppy." Richard said seriously.

You may not believe it, but Richard actually had a good time with Connor, and Mu Chen always thought it was a very outrageous thing.

Considering that Connor is a Cantare, an alien race with mind-reading skills, and Richard is the kind of guy who runs a train with a mouth, it is surprising that the two of them can come together.

Hou Ying, as the second contestant of the best man group, has already sat on the side and dozed off, if it weren't for the fact that he couldn't save face, it is estimated that he would not want to go to Richard's wedding, no way, who let him never find a girlfriend.

"If you want me to say, it's better to wear the uniform of the Reaper fleet, it's too awkward for federal soldiers like us to wear suits." Hou Ying said lazily.

"I think so too......" Mu Chen nodded and agreed.

Richard said with a headache: "Then I haven't worked for nothing?" ”

"No, isn't this a wedding dress for Connor?" Mu Chen shrugged and said.

Lin You'er's vision is still very reliable, and she took Connor around to choose the wedding dress, and the two women ran to the SPA with satisfaction, forgetting all about Mu Chen.

"Then wear the uniform of the Reaper fleet, I really wear these suits and dresses awkwardly." Richard gave up on treatment completely, "Let's go, eat barbecue." ”

It's rare for three good friends to get together again, and Mu Chen doesn't need to say much, he can't wait for 72 hours a day to be enough.

The same is true for the Eagle, as the chief maintenance engineer of the Reaper Fleet, the entire fleet has to personally take care of the maintenance matters to be relieved, and he is also a busy man.

Only Richard is a little more relaxed, front-line combatants, and it's okay to do a good job of regular training every day.

"Mu Chen, when are you going to get married?" Richard asked casually as he stroked the skewers.

"I've wanted to end it for a long time, Yaoyao is about to go to elementary school, and her two sons are about to grow up, but it's a pity that I haven't been able to find time." Mu Chen said helplessly.

"You have to hurry, it's not a matter of dragging it out like this, this woman still needs a wedding...... " Richard said earnestly.

Mu Chen smiled and nodded, it was really time to plan this matter......
