"Fuel issues." Jing Yu hugged the crystal ball, blinked, looked at Zhu Zhan Yuan, and said, "Mutated spirit coal is the best fuel. ”

"First, the heat conduction of the aura is very good;"

"Second, the aura generated can also be circulated in the heat generator."

"These are all to be prepared in advance, and after that, the location of the Refining Pavilion will hopefully be next to the coal mine." As he spoke, Jing Yu suddenly remembered something, and his heart moved, and he took out a round iron box three inches wide and one inch thick from the storage bag.

"What is this?" Looking at the iron box handed over by Jing Yu, Zhu Zhan took it curiously, and then opened the lid of the iron box.

"Huh?" Looking at the black viscous liquid in the lid of the tin box, as well as the pungent smell, Zhu Zhan couldn't help but widen his eyes slightly, and said, "This is ......"

At this time, Jing Yu held the cold crystal ball, looked ahead with a smile, and saw that she seemed to be recalling something, and then opened her mouth to read a poem.

"It's snowing in Erlang Mountain, and Xuanzhuo Qionglu is learning from the people. The plain clothes are not old in winter, and the stone smoke is like Luoyang dust. As she spoke, she looked at Zhu Zhan and said:

"This is a poem written by Mr. Shen Kuo recorded in Mengxi's pen talk."

"He was the first to discover oil and give it a name, and the people of the Song Dynasty began to exploit and use it."

"Nowadays, Daming also has some Zhuo tube wells that specialize in oil extraction."

Oil, Zhu Zhan Yuan naturally knows this thing, this is an important material for the industrial development of human civilization, known as non-renewable but like a lot of important resources.

"If the heat engine is to be widely and widely used in the construction of Daming, then coal alone is not enough, there must be this!"

"I've tried it, and when oil is burned, it can also produce mutated aura, which is basically the same as coal."

"Bang!" Jing Yu said, Zhu Zhan Feng had already taken out some oil, and then a flame rose in his palm, and after a while, he saw the oil burning, producing a cloud of black smoke, and his consciousness moved, wrapped the black smoke, and after some perception, he said:

"It's indeed a mutated aura, and the aura is even richer when the coal is burned."

"The richer the aura, the better the thermal conductivity, and I hope that in the future, some large heat engines will be used to burn with oil, such as treasure ships and the like."

"It's like a small heat engine, and it is burned with coal." Saying that, Jing Yu's tone paused slightly, and said, "So next I am going to develop a more efficient mining tool, which is why I strongly ask you to increase the number of refiners." ”

"Whew." Exhaled lightly and handed the oil box back to Jing Yu, Zhu Zhan nodded and got up and said:

"I'll tell Grandpa what you just proposed."

"But don't expect too much, in terms of the number of refiners, it is estimated that there will not be too many cultivation resources, are there any other problems?"

"It's gone." Jing Yu shook his head slightly, indicating that there was no more.

"Okay, then I'll go first." Saying that, Zhu Zhan Feng leaned down to take the spiritual root detector in Jing Yu's arms, but at this time, he saw Jing Yu's hands suddenly clenched.

"Huh?" Zhu Zhan Feng raised his head and looked at Jing Yu puzzled, but saw her purse her lips and said, "Actually, I can think of a way by myself, or improve the forging of the heat engine, and try to make it that can be built by ordinary craftsmen." ”

"Don't take any chances, lest you anger Your Majesty......"

Hearing her words, and seeing that she no longer had the tough appearance she had just now, when she was working, she was fighting with reason, Zhu Zhan was stunned, and then picked up the spirit root detector with a smile, straightened up and said:

"Ordinary craftsmen and Daming's current technology is not up to the mark."

"But don't worry, I'm in my own hands."

Seeing Zhu Zhan said this, Jing Yu didn't say anything anymore, just nodded, and stopped talking.

"By the way, you're not going back tonight, are you?" Looking at the well-behaved Jing Yu, the ghost made the gods, Zhu Zhan said this.

Hearing that Zhu Zhan Rong asked him not to go home tonight and go to his Renshou Palace, Jing Yu's eyes widened suddenly, and he looked at Zhu Zhan Yuan incredulously.

"Ahem!" Zhu Zhan Rong coughed lightly and said with some embarrassment:

"I mean, my Dan furnace has been re-refined, and I want to invite you to take a look, it's really good, and I'll build one for you another day."

"I've added some new formations to try ......"

"You're not old now, shouldn't you?" However, Jing Yu lowered his head and whispered: "You are only twelve years old now, and you have injured your body......"

Huh?! Hearing the other party's words, Zhu Zhandong's whole person was petrified on the spot.

……

Wuying Palace.

Zhu Di, Zhu Gaochi, Zhu Gaoxu, Zhu Gaosui, as well as Zhu Zhanrong and Zhu Zhanyong, Zhu Zhanji are all there.

"Is this the Spiritual Root Detector?" The old man played with the cold crystal ball in his hand, and from time to time he leaned close to his eye socket to look in.

"Dad, show me!" The second child, Zhu Gaoxu, was also a little curious about this magic weapon that could test the spiritual root, and begged the old man for it.

"You've tried it, how did it work?"

The old man looked at this rammed goods that he wanted with disgust, and directly threw the spiritual root detector to the past.

The second child didn't care about the old man's attitude, and started experimenting with the third child with a smile.

Zhu Zhanyuan nodded and said, "The effect is very good, no problem." ”

As he spoke, Zhu Zhan pointed to the Spirit Root Detector and said, "If you don't have spiritual energy, you only need two hands, one hand holding the spirit stone, and the other hand on the spirit root detector, and then the spirit gathering array in the spirit root detector will absorb the spiritual energy." ”

"After the use of the person's body, the person with the spiritual root, the spiritual energy will be captured by the spiritual manifestation array inside, and then show the spiritual root attributes."

"Wow!" At this time, I saw the second child holding the crystal ball in his arms, and the crystal ball suddenly lit up with a bright light, and everyone looked at it curiously.

I saw that in the crystal ball, plants and trees were growing on one side, and flames were entwined on the other.

Before, Zhu Gaoxu asked for a wood spirit root, focusing on dual-attribute cultivation, so the spirit root attribute presented was two scenes of fire and wood.

"Tsk!" Seeing this, Daddy Zhu Gaochi also looked at Zhu Zhan in amazement, and said, "Can there still be trees and flames in it?" ”

Looking at his father's surprised appearance, Zhu Zhan Yuan explained with a smile: "That's because I added a phantom array to it, but it doesn't have any effect. ”

"It's just because of the activation of the phantom array after Cui Dong according to the attributes."

"And the illusion of each test will not be the same, this time it is the trees and the flames, and the next time it may be the prairie fire."

Hearing Zhu Zhandong's explanation, everyone was stunned.

At this time, the old man nodded and said, "Okay, if there is no problem, then let the Refining Pavilion hurry up and produce." ”

"By the end of the year, the Immortal Cultivation Academy will also be completed."

"At that time, it will be possible to conduct spiritual root testing on newborns all over the country."

"The first batch of children after the revival of the aura is almost one and a half years old, and they can basically walk and run at that time. Coupled with the evolution of the world, the physique is also much higher than before, and the resources are used to nourish the body, and when you are three or five years old, you can start cultivating. ”

Everyone nodded in agreement.

"Grandpa, I have two more things." Zhu Zhan Yuan remembered what Jing Yu said about the problem of refining manpower and the mining of petroleum and coal.

"When I came, I met Jing Yu and mentioned some problems...... "Then, Zhu Zhan said what he was talking about with Jing Yu.

"That's the problem we're running into." Zhu Zhan said with a slight pause in his tone, and said, "So can you reduce other people's pills in the tilt of resources, and use them more to cultivate refiners and alchem......ists?"

After listening to this, the old man did not speak immediately, but pinched his beard, pondered for a while, and then said:

"You can appropriately increase the cultivation of refiners."

"But the pills can't be less, the alchemists must ensure that they have the same number as the refiners, or even more than the refiners, after all, the more alchemists there are, the more refiners!"

"I think you understand that order."

Zhu Zhan nodded his head, this was also a problem he had considered before.

"In this way, the elixir miners of the Elixir Pavilion may have less ......" Zhu Gaochi said, looked at Zhu Zhanji, and said, "Zhanji, you see? ”

Hearing this, everyone couldn't help but look at Zhu Zhanji.

Even Zhu Zhan looked at the eldest brother.

Since returning from the burial of Sun Ruohui in Yongcheng before, the eldest brother acted as if nothing had happened, and he just devoted himself to internal affairs, military affairs, and the elixir pavilion.

For a month, I never went back to the Imperial Sun Palace.

Under the seemingly calm appearance, in fact, there may be more about that incident, and I can't let go of it for a while, and I want to forget it with busyness, but seeing that Zhu Zhanji was not depressed because of this, everyone didn't worry too much, and they forgot about it after a long time.

After all, Zhu Zhanji is the grandson of the emperor, and his psychological tolerance is not so fragile.

These performances this time, in the eyes of everyone, are the most normal and deserved, and he had those mood swings before because of the catastrophe.

In this encounter, he can quickly adjust his emotions, which is the performance of an imperial grandson, and it is also in line with the identity of Emperor Xuande.

"Spiritual herb identification, in fact, it doesn't have to be a cultivator." After Zhu Zhanji groaned slightly, he said:

"In the past, the number of people was increased, but it was just to make it more convenient and faster."

"In fact, I only need to send the atlas down, even if it is a common person, I can recognize some spiritual herbs, and I can make up for these from other aspects."

"Actually, I've thought about it a long time ago, cooperate with some pharmacists in Daming, let them cook medicine, and then count it according to the contribution to them, I believe that the elixir will be collected faster."

Hearing Zhu Zhanji say this, the old man nodded slightly, and then said:

"Okay, then reduce some of the manpower of the Elixir Pavilion, and put the saved resources on the cultivation of refiners, and you will supervise this matter!"

"Yes!" Zhu Zhanji nodded and took the order.

"Alright, that's all that's been said, let's talk about the other two things." The old man waved his sleeves and said:

"A few days ago, Ma Bao sent a letter, or has already begun to return home. And then he also brought a lot of subjects from overseas vassal countries, envoys to my Daming. In addition, not long ago, the king of Joseon also sent a letter, saying that he wanted to come to the court in person. ”

"And on Toei's side, Ashikaga Yoshinori and Gokameyama have sent people."

As the old man spoke, he clicked on several surrounding countries in a row, and everyone listened quietly.

"Let's not talk about the people that Ma Bao brought back from overseas, they don't know that I have a way to cultivate immortals, let's talk about North Korea and Dong......ying first."

"These small countries have already heard about cultivating immortals, and this time the person who came was Li Fangguo, he was seriously ill, and this time he came to my Daming to seek a glimmer of life."

"Okay, let's not talk about that." The old man waved his hand, and then said, "Tell me, these vassal countries came to my Ming Dynasty to ask for immortal law." ”

"What kind of attitude do you have?"

So yes, do all vassal states also want to come to Daming to seek immortal law? After listening to the old man's words, Zhu Zhan was thoughtful.

"Give them the Immortal Law? I think they're trying to eat their fart! At this time, the second uncle Zhu Gaoxu was the first to say angrily: "Want the immortal method? ”

"Yes, directly divide the territory into my Ming Dynasty, and there will be no more subject countries from now on!"
