"Hehe!" Looking at Xiao Tianxing's painstaking meditation, Tie Shan couldn't help but smile.

"Actually, you're right, if the river water is always flowing is a good choice compared to the stagnant water in the iron bucket. ”

"But as you just said, the river water temperature is different at different times, so the best option is to make a system that guides the river water circulation. ”

"After the river water is introduced into the system, there are some special methods to keep the black water at a constant temperature, so that this problem can be solved. ”

After Tie Shan's words were spoken, Xiao Tianxing's eyes immediately lit up.

"That's right. But what is this system going to do?"

"Hehe! The branch we are building now has such a West Palace, let me take you to see it!"

"By the way, bring these two daggers. We'll take two more swords back to the furnace later. ”

Following Iron Mountain all the way to the chapter under construction, the two entered a room made of stone together.

As soon as he entered the door of the room, Xiao Tianxing immediately felt a rolling heat wave rushing towards him, and then a blacksmith furnace burning with a vigorous furnace fire also appeared in front of him.

After briefly introducing Xiao Tianxing to the blacksmith furnace, Tie Shan led him to a sink more than four feet high.

"Tianxing, you can feel the temperature of the water in this sink with your hands. ”

Putting his hand into the sink and feeling it, Xiao Tianxing's face couldn't help but be curious.

"The water is cool, and it seems to be still flowing. ”

"Hmm!" Nodding at Xiao Tianxing, Tie Shan also affirmed his statement.

"Yes, the water in here is indeed flowing, and the reason for the flow is all because of the little waterwheel outside. ”

"When the water enters this room, it is lowered to a near-freezing temperature by the ice cores I put at the sink inlet, so the water here is always at a constant temperature. ”

"However, since the water only runs inside the tank, it becomes cloudy after a long quenching, so the water in the sink needs to be changed every day. ”

"Although the water is no longer watered, it will flow into the moat through the drainage system, so it can be considered recycling!"

"Oh!" After listening to Tie Shan's explanation, Xiao Tianxing also nodded with deep feelings.

"I didn't expect to forge cookies, there is so much knowledge! It seems that it is not easy to do anything!"

Looking at Xiao Tianxing, who looked serious, Tie Shan also nodded with satisfaction.

"As for the teaching of oral knowledge, let's stop here today! How about it? Are you interested, build a sword by yourself!"

"Of course I'm interested. His eyes lit up with a glance at Tie Shan, and Xiao Tianxing's gaze immediately fell on the two broken swords.

"Are we going to rebuild these two broken swords?"

"That's right. Nodding at Xiao Tianxing, Tie Shan said what he thought.

"Since you're forging a weapon for the first time, I'll take care of it, and you'll be here to take care of the hammer. ”

"No problem! I'll just think it's training. Nodding at Tie Shan with an indifferent face, Xiao Tianxing took off his shirt and took off the bracers on his hands.

Seeing Xiao Tianxing's exuberance, the corners of Tie Shan's mouth also showed a gloating smile.

"Hehe! Later, when I am forging the sword, I will explain the knowledge of playing for you in detail. ”

"Now let's be sure of one thing: How many hammer weapons are you going to cast?"

"Hmm, 100,000 hammers! Uncle Tieshan, didn't you say that it will be tempered by a thousand hammers? I'll see if I can make it!"

"Hehe! You're pretty bold. Okay, but you have to be prepared to fight for a long time! 100,000 hammers can't be done in a day. ”

"No problem! But Uncle Tieshan, I have an idea, can you see if it works?"

"Oh? ”

"Here's what I think......" As Xiao Tianxing said what he thought in his heart, the expression on Tie Shan's face gradually became richer.

After listening to Xiao Tianxing's detailed description, Tie Shan suddenly realized that if this idea could be successful, then this might be a huge business opportunity.

"Bang!" Hearing the sound of the object falling to the ground, everyone at the dinner table knew that the chopsticks in Xiao Tianxing's hand had fallen to the ground again.

Helping Xiao Tianxing take a pair of chopsticks again, Li Yan'er looked at Xiao Tianxing's stiff hands and was full of doubts.

"Brother, what have you been busy with these days? Why can't you hold chopsticks in your hand when it's time to eat?"

"Hehe! It's okay, it's okay. I just... Smack!"

Seeing that the chopsticks in Xiao Tianxing's hand fell to the ground again, Ye Chen's face was also full of worry.

"Tianxing, what are you busy with? Why are you so tired that you can't even hold chopsticks? This is the third pair of chopsticks you have dropped to the ground. ”

"It's really fine, I'm just busy making cookies with Uncle Tieshan, and it'll be fine in a few days. ”

"But you can't afford to eat! Come to me, I'll feed you!"

"No need mother, how can I still be fed when I'm so old?"

Hearing Xiao Tianxing's words, Ye Chen immediately tightened his face.

"No, you come here. I'm tired enough, and if I can't eat well, my body won't be able to stand it. ”

"That's... Okay then!" As he spoke, Xiao Tianxing stood up, came to Ye Chen's side and sat down.

"Open your mouth, ah!"

"Ahh

It was only then that he realized that this was the first time he had let his mother feed him since he was a child.

Just when Xiao Tianxing was happily eating the food Ye Chen fed, his eyes unconsciously fell on Li Yan'er.

When she saw Li Yan'er's attachment and envy, Xiao Tianxing suddenly thought of the environment in which she grew up.

"Mother, can you also feed Yan'er today?"

Hearing Xiao Tianxing's words, Ye Chen was stunned for a moment, and then he also saw the expression on Li Yan'er's face when his eyes turned.

Under that expression full of envy and sadness, Ye Chen also thought of her affairs.

"Yan'er, come over quickly! Auntie will feed you today. ”

"Huh?" heard Ye Chen's words. Li Yan'er was happy at first, but then lowered her head and stopped talking.

"Hehe!" Seeing the scruples in Li Yan'er's heart, Ye Chen also smiled gently.

"Come here, Auntie treats you as a good daughter! It doesn't seem strange to be a mother feeding her daughter!"

"Come here! Auntie is not feeling well now, do you want me to come over?"

"Oh, no, no, Yan'er will go over. ”

After Li Yan'er sat down in front of her, Ye Chen smiled at her and stretched out the spoon in his hand.

"Come to Yan'er and open your mouth, ah!"

“... Yes!... Ah..."Slowly opening her mouth and swallowing the rice that Ye Chen handed over with a spoon into her mouth, Li Yan'er's heart suddenly felt that she was really happy at this moment.

Just when Ye Chen was feeding Xiao Tianxing and Li Yan'er to eat, Yi Han also came here.

When he saw the scene in front of him, Yi Han's face also showed a happy smile.

"Why are you two coquettish today? Who wants me to feed you?"

After Yi Han's words were finished, Xiao Tianxing hurriedly swallowed the food in his mouth.

"Dad, eat for Yan'er! In this way, she can not only experience the feeling of her mother's feeding, but also the feeling of her father's feeding. ”

Xiao Tianxing's words made Li Yan'er immediately stunned, but she still bowed her head.

"No... No need. Myself..."

"Okay, I'll feed Yan'er!" Yi Han also sat next to Li Yan'er as he spoke.

Stretching out his hand to touch Li Yan'er's head, Yi Han made a suggestion to Ye Chen.

"Madam, what do you think of letting Yan'er be our daughter? So that after the child is born, she can not only have an older brother, but also a younger sister. ”

"Okay, I like Yan'er a lot, but I don't know if Yan'er wants to?"

Biting her lip and listening to the conversation between Yi Han and Ye Chen, Li Yan'er's heart was full of this complicated emotion.

"I... I... People like me... How..."

Before Li Yan'er finished speaking, she felt that she was being hugged, and when she turned around, she realized that it was Ye Chen who was hugging her.

"Yan'er, I know what you're going to say, but please take back that thought in your heart, because we really like you!"

"You always call Brother Tianxing, isn't it because you want to have a family? Love is in us really want you to be our daughter, and we won't force you to change your surname. ”

"Don't think about anything else, just say if you want to be our daughter. ”

Raising his head to look at Ye Chen's gentle gaze, he looked at Yi Han's loving gaze, and then looked at Xiao Tianxing's expectant gaze.

Li Yan'er bit her lip and hesitated for a while, then nodded lightly.

"I... I do..."

Although Li Yan'er's voice was very small, the voice was like honey that penetrated into the hearts and spleens of Xiao Tianxing and the others.

Reaching out and touching Li Yan'er's pink face, Ye Chen's face was also full of expectation.

"Then Yan'er, since you agreed, what should you call me now?"

Raising her head and looking at Ye Chen's expectant gaze, Li Yan'er said the two words she was most looking forward to with her lips.

"Mother..."

"Hey, I'm a good girl. ”

"Yan'er, what about me?"

Looking back at Yi Han, who was also full of expectations, Li Yan'er whispered, "Dad... Daddy..."

With Li Yan'er's 'Daddy' call, Yi Han instantly felt that the one in front of him was like his daughter 'Nian'er'.

At the same time as a trace of the knot in his heart was untied, Yi Han's heart was also very clear, this was just a temporary touch in his heart.

Temporarily letting go of this trace of feeling in his heart, Yi Han also took Li Yan'er in his arms.

"Oh, my good daughter. ”

"Great! Great! Our family has increased in population. ”

Looking at Xiao Tianxing with an excited face, Yi Han's face also showed a smile that seemed to be relieved.

"Yes, let Daddy feed you two now!"

Because of Li Yan'er's happy thing, Xiao Tianxing had a beautiful dream while sleeping beautifully that night.

Early the next morning, Xiao Tianxing got up early.

After running into the kitchen and making some simple breakfast, Xiao Tianxing left the Shuai's Mansion and came to the sword-forging room of the special branch.

Today he will finish seven days of hard work and complete the first sword he forged with his own hands.
