The energy core, which is a common energy supply device for mechanical warfare, has a simple function, storing all the energy input into the interior and releasing it again when it is used.

The capacity of the energy core is very large, and it can store a huge amount of energy, and the top energy core, one can store all the spiritual energy of hundreds or thousands of high-grade spirit stones, so almost every mecha will use such a thing as an energy core.

After all, with the energy consumed by that kind of behemoth, how long can one or two high-grade spirit stones last?

The 'iron ball' in Ye Xuan's hand is the so-called energy core, and it is the energy core that Ye Xuan specially improved for the characteristics of Taiyin Qi.

In the ancestral pavilion, Qiansu was lying on a rocking chair flipping through the scrolls, while Qianyingchen on the other side was holding the grain stone in his hand and sitting cross-legged on the cushion.

"Second uncle, that kid is here, probably to find you. Chisu said lightly.

Qian Yingchen opened his eyes and put away the stone.

"Anyway, Yiyi is also a hard-working child, just go with him to have a look, it's a good thing to be able to help. ”

Seeing Qian Yingchen pushing the door out, Qian Yi hurriedly wanted to speak, but saw Qian Yingchen waving his hand and said, "Let's go." ”

"Xie Lao Zu. ”

led all the way, Qianyi sent Qianyingchen into the house, and took Xiaorou out of the house.

"You are Yiyi's master?" Qian Yingchen frowned, he had already heard from Qian Yi about Ye Brand, but he didn't expect that Ye Branding would be so young.

Ye Xuan didn't lose his manners, and he knew that this was not an ordinary person just now.

"Senior, time is pressing, now is not the time to question, please be sure to protect me with fire patterns later, dissolve the cold, juniors are here to thank you for Yiyi!"

"Hmph, let's start, the old man can do it at any time. ”

Ye Xuan nodded, put his hand into the hem of Qian Yiyi's clothes, and pressed it on her lower abdomen, Qian Yingchen didn't say anything, he sat down behind Ye Xuan, and gently pressed his hands on Ye Xuan's back, like flowing water, the lines spread from Qian Yingchen's hands to Ye Xuan's body, but there was no harm to Ye Xuan.

Looking at the high-grade lines that spread to his arms, Ye Xuan's heart was settled.

The cold air was sucked out by him and poured down his arm into the energy core.

Qian Yingchen's face changed, and only then did he feel the true power of the Taiyin Qi, and he hurriedly activated the power of the tattoo to dissolve the invasion of the cold qi!

As time passed, Ye Yan's face became more and more pale, and Qian Yingchen's hands were covered with a layer of frost at some point!

At a certain moment, Ye Yan slowly withdrew his left hand, but found that his left arm had already lost consciousness.

"Senpai, I'm in trouble!"

Qian Yingchen grabbed Ye Brand's arms, dozens of high-grade lines spread up, and the huge popularity slowly seeped into Ye Brand's arms, and it took a long time for Ye Brand's arms to recover as before.

Fortunately, he had long known the horror of Taiyin Xuanqi, and the inner and outer three layers protected the meridian bones with patterns and Xuanqi, otherwise, these arms would be useless.

Looking at the time, six hours have passed.

"If you have a little ability, you won't suffer if you hand it over. Qian Yingchen said lightly.

Even he couldn't solve the cold, Ye Xuan was able to solve it, and seeing that he saved Qianyiyi regardless of the risk of his arms being abolished, obviously, he was still very good to Yiyi, an apprentice.

Ye Xuan threw away the energy core in his hand, and smiled faintly, "Senior, don't worry, according to her qualifications, I won't hurt her, these cold qi, I will teach her how to control and use it." ”

"What, can these cold qi be controlled?" Qian Yingchen was shocked, such a cold air, even his high strength was difficult to resist, Ye Xuan actually had a way to let Qian Yiyi control it!

"Of course she can, and only she can. Ye Xuan didn't say much.

Qian Yingchen was shocked, if Qian Yiyi could control this terrifying cold, then how could the royal family look at the faces of those people in the future?

Suppressing the shock in his heart, Qian Yingchen noticed the 'iron ball' in Ye Xuan's hand and asked, "What is this, it seems that all those cold qi have been sucked into this 'iron ball'?"

"I made a gadget that can store the cold in Yiyi's body, and when she can control the cold in the future, let her inhale it again, which will be of great help to her strength. Ye Xuan said.

"Let the old man see. ”

"Senior take it lightly, if this thing is broken, the entire palace will have to be frozen. Ye Yan admonished.

Qian Yingchen naturally knew that what Ye Xuan said was true, after all, he personally helped Ye Xuan just now, and he naturally knew how terrifying the Taiyin Qi was.

After a careful observation, Qian Yingchen didn't see anything famous, and carefully returned it to Ye Xuandao, "Yiyi will be handed over to you in the future, you still have to keep this thing, she is a hard-working child, take care of her." ”

"Uh... I will take good care of my precious apprentice, please rest assured seniors. Ye Xuan deliberately said the two words of apprentice heavily.

Qian Yingchen naturally understood what Ye Xuan meant, but Qian Yiyi was so beautiful, he didn't believe that Ye Xuan, a young man, would not be moved.

"Just take care of her. Qian Yingchen turned around and walked out, but when he reached the door, he asked, "How long will it take for Yiyi to wake up?"

"I can't guarantee when I will wake up the junior, but it will take three full days to clear the cold!" Ye Xuan also walked to the door.

"Call me anytime. After speaking, Qian Yingchen left with his hands in his hands.

"How is it, Brother Ye, is my aunt awake?" Qian Yi hurriedly asked when he saw Ye Xuan coming out.

Ye Yan shook his head and said, "How can it be so easy, it will take a few days." Alright, you prepare some food for me first, I'm dying of hunger, let me rest, and come back in the evening. ”

"Come on, prepare food!"

After Qian Yi finished speaking, she rushed in to look at Qian Yiyi, and saw that there was a little more blood on her face, and the worries of many days finally turned into a smile on her face.

"Brother Ye, let's go, let you have a good taste of the craftsmanship of the imperial kitchen!"

"Then I have to taste it, if there is anything delicious, you can go out, I have been trapped in the Biyin Domain for seven years, and today I have to open the meat." Ye Yi smiled and left the palace with Qianyi.

When he came to Qianyi's dining place, Ye Yan was dumbfounded, such a big table, good guy, full of dishes, at least more than 100 dishes! This is enough for dozens of people to eat!

"My God, it's good to be an emperor, this is so damn meow, magnificent!" Ye Xuan exclaimed.

"These are all prepared for you before, and it is enough to let the imperial dining room cook more than ten dishes when I usually eat. Qianyi said with a smile that he has always disliked extravagance and waste, so naturally he would not do that kind of thing.

"Hey, you only ascended the throne last year, how does it feel to be an emperor?" mentioned this in the information provided by the sprouts, and Ye Yan remembered.

Qian Yi shook his head, the test of many years finally made the civil and military officials recognize his ability, but this emperor was too tired, suddenly, he saw a person coming over from Ye Xuan, his eyes lit up, and he smiled and said, "Don't talk about this, come, let you see someone!"

As soon as he finished speaking, a eunuch rushed in, "Your Majesty, General Liu and Prime Minister Du Cheng have been waiting for a long time." ”

Qian Yi thought of the two of them, nodded and said, "I'm happy today, let them come in and eat together." ”
