I picked up the dragon girl at the beginning and I used artillery fire to liberate the other world

There are rich reserves of mithril mines buried underground in the Mithril City, the value of which is enough to buy a large city.

As an essential metal for crafting magical weapons, mithril has always been mined with great care by the Exash Empire.

And now all this wealth has almost fallen into Bai Yan's pocket.

However, he did not plan to sell these precious metals.

Because Bai Yan discovered that it not only has a high affinity for magic, but also has extremely strong conductivity to electricity, an energy body that still belongs to the category of magic.

As for how strong it is, Bai Yan still needs to test it carefully with a relatively weak electric current to find out.

After all, magic is also a form of energy, and any energy will be exhausted one day, unless other energy is continuously converted into magical elements.

Bai Yan sat at the desk in the newly built lord's castle of Black Iron Castle, looking through the window at the giant moon in the sky.

As bright as jade and round as a whole, the moonlight it emits does not seem to be reflected starlight, but rather appears to be emitted by the moon itself.

After slowly writing down "moon and magic" in his notebook, Bai Yan closed the notebook.

Once the railway tracks are laid, a steady supply of mithril will be transported to the Black Iron Castle, and by then, we will enter the electricity age.

A convenient energy source that can be controlled and delivered sustainably. The night will no longer be shrouded in darkness and various equipment can be put to use.

Bai Yan was thinking about future plans when he suddenly felt someone tugging at his sleeve. He turned around and saw it was Iris.

"What's wrong? Can't you sleep?"

Bai Yan smiled at her and rubbed her head.

Iris shook her head, then slowly put her arms around Bai Yan's neck and put her head on his shoulder.

“Worried about me?

It's okay, with your sister Alicia here, nothing will go wrong."

Iris pursed her lips, let go of Bai Yan, took out her little notebook and started writing.

【Bai Yan, I want to sleep with you. 】

When Bai Yan saw this sentence that could easily lead to erroneous thoughts, his expression became helpless, "Why do you want to sleep with me? Are you afraid of sleeping alone?"

Iris stood there coquettishly, shook her head, and continued to write [Sleeping with you is very comfortable. You are so warm and fragrant. ]

"But men and women cannot sleep together when they grow up, except as couples." Bai Yan moved aside to make a small space for Iris on the chair and let her sit on it.

The handrails on both sides held the two people tightly together, and it seemed somewhat cozy under the dim light of candlelight and magic crystals.

Iris's long blonde hair hung down her back and temples. She twirled her hair and continued to write in her notebook, "If we become a couple, can't we sleep together?"

Showing Bai Yan this sentence, Iris' eyes were still pure and peaceful, like a piece of white paper without any words or dust, quietly looking at Bai Yan.

Bai Yan's eyes became more depressed. He looked at the cute and silly eyes of the elf for a while, and finally sighed, "If you want to sleep with me, then sleep."

Hearing this, Iris nodded quietly, pursed her lips, and seemed to reveal a smile.

The next day, Bai Yan opened his eyes, gently lifted the quilt and saw Iris in his arms with her pointed ears moving. She was like a kitten, nestling in Bai Yan's arms with a smile on her face.

Her golden hair became a little messy, her nose was straight and she murmured in her sleep from time to time.

After carefully putting on his clothes, Bai Yan opened the door and walked out.

The newly built lord's castle was much larger than the previous one. As soon as he opened the door, Sophia with a golden ponytail stood in front of him, holding her waist and frowning.

She was still wearing the scarf that Bai Yan had given her. As if she noticed Bai Yan's gaze, Sophia's frown relaxed slightly.

"It's so late, why don't you get up?! Come with me to run and exercise."

He muttered to himself, pulling Bai Yan's sleeve, went downstairs, went out the door, walked across the street, and went out of the city gate.

"Where are you taking me to run?" Seeing that the surrounding environment had turned into mountains, Bai Yan's mouth twitched and black lines appeared on his forehead.

"Today's mission is to climb to the top of the mountain and then return."

Sophia inserted her fingers backwards, stretched her body, and looked full of energy.

"You haven't recovered yet, what should you do if you encounter danger?" Bai Yan leaned against a tree, held on for a while and stood up straight, "Listen to me, just run two kilometers for your sake."

"No! It's fine for ordinary people to run like this, but cultivators like you and I must have sufficiently intense training to achieve a faster training speed.

I’m doing this for your own good.”

Without waiting for Bai Yan to refute, Sophia grabbed him and ran.

Dark Forest, Bai Yan and Alicia have been there many times.

However, the war is still going on at the front line, so he arranged Alicia and Constance there just in case.

The Mithril Capital was captured, but Charles obviously did not intend to give up this city that contained huge wealth.

A full 100,000-strong army, relying on their flesh and blood, charged towards the northern wall of the Mithril City in the north.

Although it was a bit stupid, Bai Yan always felt that things were not that simple.

. . .

"I, I can't do it anymore." Bai Yan supported his knees with his hands, gasping for breath. Despite this, he still felt incredible about his physical fitness.

For nearly an hour, Bai Yan used all his speed to catch up with Sophia. In the past, he would have fallen to the ground in less than five minutes.

"Your cultivation is pretty good. Take a rest first and run again later." After saying this, Sophia leaned casually against a tree and let the wind lift her hair.

Bai Yan was breathing heavily, and suddenly he seemed to hear a few roars.

The sound came from far away and gradually got closer, accompanied by the ground shaking. A huge white-eyed tiger with its neck hanging pounced towards Bai Yan.

“Wow, how come this tiger is so big?” Bai Yan yelled and hid behind Sofia.

However, originally the Valkyrie would have slapped the giant tiger away, but in the end Sophia dodged and made way for the tiger.

Looking at the huge fangs exposed from that mouth, Bai Yan's heart was astonished. All the nerves in his body tensed up, and he didn't know why he stretched out his hand and released a huge fireball.

A fiery red magic circle appeared out of thin air, and a huge fireball with a diameter of half a meter smashed towards the fat tiger like a meteorite.
