Even though he knew that this kind of thing was an extension of the influence of the Physicists, Marshal Carr still did not stop it.

After all, compared to the prince of a country who went to work as a self-funded student for the Tesla archmage, the defenders of the 'individual' demon's mouth chose to mix with the physics school, which is really not a big deal.

The marshal still made a report as usual, and as for whether anyone was in charge or not, he didn't care.

Anyway, the physics school counts his own people, and he can defend this fortress well, and the rest has nothing to do with him.

On the other side, Wren was busy.

While he had to teach the sixth disciple Vodak, he was busy asking Barend to help build the Gundam, ahhh

With nearly a hundred dwarven craftsmen and thousands of tons of rare metal ingots provided by the Iron Hand Clan, Barend's workshop was finally fully operational, and it entered a state of intense research and development experiments.

Because to build such a thing as Gundam, one is not in a hurry, and the other is laborious. Wren doesn't lay out in advance and set various standards, otherwise once the technology tree is crooked, such as making a hydrogen energy Gundam or something, it won't be fruitful for decades.

Wren was so busy that he had to leave the chores to his eldest disciple, Downs.

"Those government-funded students and Marino's self-funded students taught them all junior high school physics, right?"

"Yes, Master. There are a few that still have a little hope. ”

"Okay, I'll assign a few topics and let them figure it out for themselves."

The laws of high school physics can't be taught, after all, it's easy to be greedy and chew too much, and it's definitely not because [that's another price]...... A certain archmage who recently looked at the financial statements and had a painful egg said.

Wren turned his head and instructed Downs, "I'm going to be busy with Barend's workshop and teaching your sixth junior brother. On the side of the Devil's Mouth Fortress, you are the supreme leader. ”

"Ahh What if a demon lord kills him? ”

"How could a demon lord descend on the Kaos continent so easily? Anyway, you can kill the demon casually, you don't have to tell me. ”

"Master, let me confirm again, is it okay as long as the demon does not break through the demon's mouth fortress?"

"Well, try to keep the defenders in as few losses as possible. When I'm done, I'll start reclaiming the Stronghold's Mage Towers and completely restoring the Stronghold's defenses to their historic peak. ”

"Understood. The mouth of the devil will be handed over to my disciple. ”

Looking at the extremely deferential Downs, Wren was comforted: What a good boy! Why do I sometimes think that Downs is like a phone bill?

Wren was relieved to run back to the academy headquarters.

The Devil's Mouth saw that it was Downs in charge, so he naturally had nothing to say.

No one knew that after Downs officially took office, the first thing he did was to run to Harry: "Senior brother, are you interested in making waves?" ”

Harry was a little surprised: "Senior brother, you are finally willing to find a woman?" ”

Downs slapped Harry on the head: "Don't learn well at a young age!" Just think about some nonsense. ”

"What! Master is not ...... with the Archduke yet."

"Smack!" Another slap in the face.

Harry didn't dare to argue.

"How can we compare to Master? Master, he adapts to the laws of this world and takes back his due strength! We are climbing from the bottom up. Tell you, you are obsessed with women now, in case your strength stops at the master level for the rest of your life, looking at the junior brothers and sisters who have become legendary mages, do you still have the face to claim to be a disciple of the master? ”

Downs's well-founded lesson made Harry awe-inspired: "Whatever the senior brother says, I'll do it!" ”

Looking at Harry's burning eyes, Downs smiled, "This is my good junior brother." ”

"Senior brother, what is the goal?"

"I want to ...... Get the demonic fortress Alexnon across from the Devil's Mouth. ”

“……”

"Think about it, where did we physicists get this kind of bird gas? Only beaten and not fought back? ”

Harry thought about it, too.

We physics school, revenge never overnight.

We can't stand this anger!

Seeing Harry's changed eyes, Downs's smile became brighter and brighter: "Have you noticed that in addition to letting the original owner write the transfer of the title deed, in fact, the [Land of Physical Legends] can be expanded." ”

When Harry heard this, he immediately looked into the distance.

This is not an illusion, as the more towers and traps of the Physics School kill, the more land occupied by the Legendary Physics Land has a tendency to spread deep into the Devil's Mouth.

Harry tentatively asked, "A solid foundation? ”

Downs was determined: "A solid foundation!" ”

As the saying goes, what kind of master teaches what kind of disciple he teaches.

Wren is this virtue, what kind of good-tempered and humble gentleman do you expect to be an apprentice?

In this way, Downs made a report to Field Marshal Karl. It's not very demanding, it's just a bunch of polished convex lenses.

Carl was supportive of anything that would greatly strengthen the fort's defenses.

Within a few days, a large series of convex lenses stretched from the outside of the fortress to the depths of the cave, and the defenders of the fortress felt equally fresh to see the sunlight that should not have reached this place reaching the deepest part of the cave after a few refractions.

[Light of Heaven] This thing is very good-looking, and its lethality is also good.

It didn't take long for the whole fortress to know how the 'solid foundation' of the physics school came about.

Thousands of demons were reduced to slag by the divine brilliance, then molten to a molten state, and finally cooled down into a large glass-like thing.

Originally, the corpses of the demons were scattered everywhere, and the glass created was unevenly scattered in all corners of the cave.

Who knew that after Flora took over, she would use the [Heavenly Light] to sweep the ground outside the first line of defense back and forth when she was free, so that the [Demon Glass] would be evenly smeared on the ground.

As a result, within half a month, there was an additional [Heavenly Road] with a maximum width of 1.4 kilometers and a narrowest kilometer in front of it.

Not to mention, this thing is definitely a deterrent to demons.

Don't say anything.,When the demon comes up, please take a will test first.,If you can't pass it, you will enter a state of chaos on the spot and lose your mind.。

Originally, the demons were difficult to command, and no matter how clever the demon commander was, he could only drive the demons under his command in a general direction, and once the enemy was found, he would let his demons play freely.

What a match, what a queue, this thing never existed in the demons of chaos and evil.

The appearance of [Road to Heaven] made the destructive power of the demon army drop by more than one notch on the spot.

It's not that there are no demon commanders who are trying to destroy this 'path of goodness' that makes them feel extremely uncomfortable. The question is, is the fact that they can attack this glass road, does it also prove that they have entered the range of the convex lens?

"W-"

The 'solid foundation' continued all the way in the direction of the Abyssal Rift.

Soon, the demon boss here couldn't sit still.
