"Master Dean, what is this tail wing used for? Why do we need two wings in front and behind?"

"You see, all birds have tail feathers, right? That's the inspiration for the tail wing," Lynn said with a smile.

Lydia was stunned for a moment, but soon reacted. Indeed, both powerful monsters and ordinary birds have long tail feathers on their backs, and even dragons have long tails.

"That's used to maintain balance and assist steering, right?" Lydia quickly guessed.

"That's right." Lin En nodded. Learning from nature is often an extremely important part of obtaining design inspiration.

After understanding, Lydia pointed to the modified wing.

This was what surprised her even more. The wings drawn by Lin En were not completely straight, but curled up at the ends. This was very strange, because no bird has wings with upright tips.

"This involves knowledge of aerodynamics. Simply put, it can block wingtip vortices, reduce induced drag, and increase the limited aspect ratio..." Lin En explained endlessly.

Lydia felt dizzy after hearing this. She had no idea what wingtip vortices and aspect ratios were...

"How about this, we can try folding two paper airplanes!" Lin En thought for a moment and said.

Lydia immediately became excited. The paper airplane was something the dean had taught her. It was a very interesting flying toy that could be made with just a piece of paper. The principle of flight was very similar to the way she made her aircraft. It was like a smaller version of a self-powered aircraft model.

During this time, she also developed a new folding method that can fly very far...

Lydia trotted over and quickly brought back two pieces of paper of the same size. She handed one to Lin En and then folded it quickly.

A delicate paper airplane soon appeared in the girl's palm. After looking at Lin En who was still folding paper, Lydia took a running start and threw the paper airplane out.

As the saying goes, great strength makes miracles happen!

With Lydia's full strength, the paper plane flew nearly thirty meters away before landing shakily on the ground.

Lydia happily put her hands on her hips and looked back at the dean. This was the farthest that she had ever flown among all the paper airplanes she had folded! "Is it my turn?" Lin En folded the wings into an upward shape. He didn't intend to stand up, nor did he use too much strength. He found the right angle and pushed the paper airplane away from his palm with a light push.

Ten meters, twenty meters, thirty meters...the paper plane still showed no signs of decline. It even circled in the air and returned to Lin En's hand.

Lydia was so stunned that she began to suspect that the dean had secretly cast a spell to cheat...

But then he immediately remembered that the dean couldn't cast magic now! "You can try it yourself!" Lin En shrugged. He naturally saw the girl's doubts.

Lydia picked up her paper airplane in disbelief, made a small change to the wing, and then tried it again immediately.

Due to the different angles, the paper plane did not fly back, but it also easily broke through the 50-meter mark...

After Lynn demonstrated the superiority of the new design through practical actions, he discussed with Lydia the material issues involved in manufacturing the new aircraft.

Lynn is also very concerned about this thing.

Aircraft are real weapons for air combat, and using airships for air defense is not the right way after all. This time they used the newly developed laser magic to catch the enemy off guard and wiped out an entire Griffin Knights! But such a tragic lesson will also make the Church more vigilant.

They have used it more than once, whether in the defense of the royal capital or in naval battles. Now that the information about laser magic has been exposed, it will be difficult to have such a good record next time.

And this new aircraft will become their new air combat ace...

…

For the next two days, Lin En stayed in the manor and enjoyed a luxurious life with everything provided for him, and from time to time he guided Lydia in making the aircraft.

During this period of time, the Vatican has been very quiet and has not made any major moves. At least the airships they sent out for reconnaissance did not find that the Empire had any intention of invading again.

Lin En guessed that the disastrous defeat of the two expeditionary forces would be enough to damage the entire empire...

In addition, the Empire's expeditionary fleet may still be floating on the sea at this moment, and war is unlikely to break out again in the short term.

However, although their strength was strong, it was far from enough to intimidate the Holy See. At most, they were a little apprehensive. It was foreseeable that once the other side launched another attack, they would definitely organize a more powerful force...

After ten days of recuperation, the vague pain in his brain had completely disappeared, which also meant that he had regained his ability to cast spells and could finally fool several legendary speakers in the magic field.

This is undoubtedly the top priority right now. On the one hand, it is to guide wizards to explore more microscopic areas and find ways to defeat the false god [Ella]. Secondly, it can also add bricks and tiles to his magic network and increase more computing power support.

Although the computing power of the magic network is now sufficient, and even exceeds the maximum limit he can bear, it is always a good idea to plan ahead. This time, risking brain death, Lin En has taken a step closer to controlling and mastering magic power. He feels that he is getting closer and closer to becoming a five-ring wizard!

"By the way, 071, weren't you unable to mobilize the wizards' computing power across levels before?" Lin En suddenly thought of a question and asked silently in his mind.

Before, when he was just an official wizard, he tried to mobilize the computing power of a great wizard like Anthony, but the response he got was that he couldn't, because the other party's spiritual level was higher than his, and he could not bear the power of any great wizard.

It was not until after a successful breakthrough that a positive response was received.

In Lin En's opinion, the gap between a great wizard and a legendary wizard should be quite big. He was somewhat surprised that he could mobilize Harof's computing power just after he entered the realm of a great wizard.
