The atmosphere in the city was a little oppressive, the steppe army had already surrounded the city of Linfeng and launched an attack, and even in the center of the upper city, the sound of trumpets could be faintly heard from the other side of the city wall.

Affected by this, the people of the city were panicked, and the residents took refuge in their houses, secretly praying that the defenders would protect them.

On this side, after issuing an urgent commission to the Alchemy Society, Nolan also returned to his laboratory and continued to complete the production of the spiritual pathway.

He didn't think much about the situation on the battlefield, because he knew that the defenders could hold the city walls, and at least they could last a day, until he made the city defense magic cannon.

With the intervention of the White Raven, the barrier circle was not destroyed, and the large forces of the Knights were withdrawn from the Eastern Front in time before the decisive battle.

Even if the firepower of the five city defense magic guide cannons is temporarily lost, the Linfeng City at this time is not something that the grassland people can easily capture.

With the bottom in my heart, I naturally don't panic.

Warriors are responsible for killing enemies, alchemists are responsible for crafting weapons, everyone has their own job, and everyone has their own thing to do.

Amid the non-stop sound of trumpets, the battle outside the city continued into the night.

At the same time, after hours of overtime work, the doors of the laboratory, which had been closed, finally opened.

Nolan yawned and walked out of the lab, stretching hard.

Just now, he finally made all the remaining psychic pathways needed to modify the Valkyrie backpack.

As long as it is handed over to Luo Zhen and asked him and his alchemy team to install the new mechanism on the backpack, the Valkyrie equipment will be officially iterated and fully evolved into a "psychic induction" control method.

Thinking of this, the fatigue on his body was also reduced, and Nolan came to the studio of the doll shop next door, at this time, Luo Zhen was sitting in front of the production table and snoring.

He just wanted to wake up Luo Zhen, but Ai Xia on the side quietly tugged at his sleeve and made a shushing gesture at him:

"Daddy performed an operation on Yuna in the afternoon, and then he was busy with other things, and now he just fell asleep, so don't bother him!"

“…… Again, I owe it to me. Hearing her words, Nolan scratched his head with a wry smile.

Speaking of getting on his own thief ship from Luo Zhen, he hasn't rested for a day, and he helps himself make equipment every day.

Although he was very busy during this time, the energy of young people is not the same as that of middle-aged and elderly people, and it is still necessary to reduce his burden in order to prevent his uncle from dying of overwork.

"So, it's good to ask my sister for something!"

Ai Xia straightened her chest and said seriously, "Don't underestimate me, after so long of fighting with Daddy and Mr. Lu Di, I can already complete the general work very well!" ”

"Well, the work of installing parts is really not difficult, but the workload is relatively large, and it can be regarded as a delicate job...... It may be appropriate to leave it to a girl. ”

Nolan nodded with a deep groan, and then reacted, "What the hell is my sister, when did you become my sister?" ”

"Well, don't worry about these details!"

Aisha gritted her teeth and said, "Hurry up and hand over the newly made props!" I'll go to the weapons shop and work with Mr. Luti to see if I can get the new equipment ready by this morning. ”

"It's so reliable." Nolan let out a long breath, "I'll leave it to you over there, come with me to the lab to get something." ”

When the matter was settled, he walked back, and Aisha followed him step by step, and said with a smile: "So that you can have a good night's sleep tonight, right?" Recently, you have been sleep-deprived like your father, so take good care of yourself. ”

"I'm afraid I still won't be able to sleep."

Nolun Waner, "The people of the Alchemy Guild will be able to send the city defense cannon over as soon as tonight, and I still have to go to the acceptance, engrave the magic circle, and send it to the military headquarters as soon as possible." ”

As soon as he finished speaking, he saw a truck speeding from the other end of the road and stopped at the door of the workshop.

In charge of escorting the delivery cart were several knights of the sixth squad of the Knights, and when they saw Noren at the door, they immediately dismounted and saluted:

"Lord Nolan, the first batch of goods from the Alchemy Guild has been delivered!"

"Move it in." Nolan bowed slightly, then shrugged his shoulders at Aisha, "Look, I'll just say I can't sleep." ”

Although there was a helpless tone and expression, Aisha could see that he was not expressing his dissatisfaction, and could even be said to be enjoying it.

Yes, Nolan is such a person, she has always known it.

She first met Nolan one day when she was seven years old, and she was fiddling with the doll in front of the store when she stumbled upon a boy about her age sitting outside the workshop next door.

The boy leaned over and asked in a milky voice, "What are you looking at?" ”

The boy turned his head and glanced at her and the doll in her hand, and said something that was out of his mind:

"It's nothing, I just think the sky in Uptown is bluer than I've seen before."

She didn't understand what this meant, so she automatically ignored it and asked, "Are you my new neighbor?" My name is Elsa Kandel, what about you? ”

"Me? My name is Nolan Wieses. ”

"Hey, are you a relative of that Mr. Rasti Vises?" She was surprised, "Will you become an alchemist too?" ”

"Relatives? I'm his apprentice, huh...... I guess it's an adopted son. ”

The boy turned his head back and continued to look at the sky, a smile on his lips.

"Yes, I'll be an alchemist. I will definitely be ...... An alchemist who is better than everyone else. ”

At that moment, unlike his peers who only knew how to play with toys, his eyes were so pure and bright when he looked at the sky, as if a smug teenager was challenging the whole world.

Confident to the point of arrogance, but so full of courage.

She thought that maybe she had been concerned about him from that moment.

His face was tired, but his eyes were as pure and bright as they had been ten years ago, and she knew he was enjoying the process.

Now even his strict father is very satisfied with him, and he can even easily mobilize the knights to let the entire alchemy learn to do things for himself.

He really achieved his goal and became a very powerful alchemist.

It's just that he kept looking up and forward, and he was almost out of reach.

Talented people are attracted to each other, Yuna, Evelyn, and Daddy...... I don't know when he has had a lot of powerful partners around him.

Looking at his back as he walked towards the lab, Aisha clenched her little fists and quickly followed.

That day, she whispered a conversation between Nolan and her father, and if Nolan's feelings for her were family and friendship, it would be fine.

If you get too close, you will be burned by his light, and if you are too far away, you will feel lonely, between geniuses and ordinary people, maybe this distance is just right.

But...... Even so, there is a kind of unyielding energy burning in her heart, urging her to keep moving forward.

She also wanted to show Nolan that even she could do it.

Sister, I'm also very serious when I'm serious!

……

In the laboratory, Nolan watched the scrappy Essya leave with the psychic pathway.

Young people are full of energy.

With a sigh of emotion, he closed the door, and then set his eyes on the large box sent by the Alchemy Society.

When I opened the cargo box, I saw a slender cannon barrel two meters long and thirty centimeters wide, which was the spell generation port of the new city defense magic guide cannon.

The barrel is fixed to a large gun carriage, the base of which is the structure of the circle, on top of which the mana source is stacked, and above is the sight and control switch of the battery.

Four wheels were also installed under the gun mount, which allowed the battery to move.

Because the base of the magic circle is only one meter and five meters long and wide, the volume of this new city defense magic cannon has been qualitatively reduced compared with the old seven or eight meter-sized fortress-type magic cannon.

Although its mana source is smaller than the Fortress Magic Cannon, its mana source is made to be easily disassembled, and can be quickly replaced even if the mana is depleted.

Not only does it take time for a circle to generate a spell, but activating the circle continuously in a short period of time will also cause a large amount of unstable mana to accumulate in the circle and the mana channel.

This puts a strain on the components involved, and in severe cases, it can be destroyed, and the more advanced the circle, the longer the cooldown time will be required after the spell is released.

Therefore, as long as the mana source is changed during the cooldown interval after the turret activation, the new magic cannon theoretically has the exact same power and rate of fire as the old version.

And because it is lightweight and miniaturized, it has lower manufacturing costs, faster production cycles, smaller maintenance costs, fewer personnel responsible for control, and higher mobility.

If the enemy is attacking on one side of the gate, several city defense guns can move to one side at the same time and concentrate their fire on the counterattack.

This is also an advantage that cannot be matched by the immovable fortress city defense artillery.

After checking whether the parts of the new city defense gun were missing, Nolan pulled out the magic circle structure at the bottom of the gun carriage and placed the base of the one-meter-five long and wide magic circle on the ground.

Then he put his hand on the base, and the book of omniscience in his mind turned to the page of the sixth-order spell "Heavenly Burning Flame", and silently recited:

"Projection."

The light converged, and in just a few breaths, a circle of red magic circles with a diameter of about fifty centimeters had been engraved on the base of the magic circle.

That's right, the size of the perfect circle of the sixth-order spells projected by the Book of All-Knowing and All-Knowing was actually only fifty centimeters, but it was only half a meter in length.

If it's this size, it's actually the size of a single weapon.

However, instead of doing so, he deliberately left the base of the circle large and designed it to be in the shape of a mobile turret.

Among them, he has several considerations, the most important one is that even if the size is deliberately large, compared with the old version of the city defense gun, it is small enough and flexible enough to fully meet the needs of defending the city.

As for the city defense cannon in the form of a single weapon, he also asked the Alchemy Society to make a copy in the name of an experimental weapon.

This will be a strategic-level magic guide that belongs exclusively to the White Raven and is enough to change the entire battle.
