Zhu Zhan came to the round, very clean, and still looking young iron-eating beast, stretched out his hand and gently touched his head.

"Humph!" Touched by Zhu Zhandong, the iron-eating beast cub let out a shrill snort, and avoided Zhu Zhanyuan with a swing of his head.

With this cute look, Zhu Zhandong's heart really melted, especially the two big fluffy black ears that stood up.

As soon as his heart moved, Zhu Zhan grabbed it.

Hey, this feeling, it's so cool, in the last life, he watched the animal keeper scratch the panda's ears, and he was called envious.

It's a pity that when I went to the zoo before, I didn't have a chance at all.

After playing with the iron-eating beast for a while, Zhu Zhan came to the half-human height again, well, compared to him, he was already almost in front of Bai Ji who was the same height as him.

Especially the mighty and domineering one-horn, as well as the sturdy figure like a mobile fortress, I only feel an unprecedented sense of security.

Of course, he doesn't need a spirit beast mount to act as a sense of security.

"Haha, how's that? Like it, right? Second Uncle Zhu Gaoxu came up at this time, patted the white man's strong belly with a smile, and said: "This white man and the iron-eating beast are all carefully cultivated by us, and the most important thing is that they have the highest spiritual intelligence!" ”

"The iron-eating beast has the ability to spit ice, Bai Yu has the ability to spit fire, if it is in a combat state, Bai Yu is covered in flames, and his body can skyrocket to six zhang!"

"This is still a child, and when you become an adult, it will be even more powerful!"

Zhu Zhan Feng listened to the words of the second uncle and the third uncle, looked at the two rare beasts with satisfaction, squinted his eyes, and said, "Thank you second uncle and third uncle, I like these two gifts very much." ”

"Haha, if you like it!" Second Uncle Zhu Gaoxu and Third Uncle Zhu Gaosui glanced at each other and laughed.

Before, Zhu Zhan opened various small stoves for them.

The brothers also thought about how to repay the favor and give Zhu Zhan Feng some gifts.

However, as soon as they thought of Zhu Zhandong's cultivation and there was nothing missing, the two of them stopped firing again.

Now that the two of them have mastered the cultivation of the Ming Dynasty's imperial beasts, they slapped their heads and thought about getting two good spirit beasts for Zhu Zhanyuan.

As a result, the legendary iron-eating beast and the beast became the first choice of gifts for the two.

After seeing the two leave, Zhu Zhan Feng smiled, looked at the two little guys in front of him, and with a wave of his hand, he loaded the two beasts, and then walked out of the Xuanwu Gate.

Refining Chamber.

"Master?!" Seeing Zhu Zhan Rong appear, he was busy with the public loss, his eyes suddenly lit up, and he shouted in surprise.

She hadn't seen Zhu Zhan Yuan for more than a year, and she was naturally very surprised to see Zhu Zhan Yuan.

Putting down a gear in hand, he trotted to Zhu Zhan and said, "Master, when did you come back?" ”

Look at the wet and sticky hair on her sideburns, the fine sweat on her forehead, and the lingering tiredness between her eyebrows.

I haven't seen her for more than a year, and this girl's cultivation has broken through to the transition stage of refining and refining qi to refining qi and transforming gods, and it seems that the lotus heart in her body has begun to appear.

Of course, at this time, the original group of people in the Refining Pavilion were basically promoted to the third stage of refining and refining qi by forcibly pulling out seedlings by themselves.

It is not easy for these people to break through!

It stands to reason that it is unrealistic to want to break through the Qi Refining and Transformation God within a year, let alone that they are still remnant spirit roots.

Now that the public loss has not come to this point, it is enough to see how hard she has worked behind her.

"I've seen the emperor's grandson." At this time, the refiners of the entire first layer, when they saw Zhu Zhandong, immediately stopped what they were doing and saluted one after another.

"Good work." Zhu Zhan said with a smile and patted Gong Weiwei's shoulder. This time, he did not refuse this girl's title of 'master' to himself.

was patted on the shoulder so affectionately by Zhu Zhandong, and he was also flattered by the loss, and his bright eyes were about to squint into a crescent moon.

"Come back this time and lighten your work!"

"Really?" Hearing Zhu Zhan said that he wanted to lighten the work for himself and others, Gong Yi didn't seem to think of something, and said, "Is it a machine tool?" ”

"You know?" This time, it was Zhu Zhandong's turn to be surprised.

"Hee-hee!" Looking at Zhu Zhandong's surprised eyes, Gong Yiwei smiled playfully and said, "What the master said." ”

Hearing her say that she was a teacher, Zhu Zhan was slightly stunned, and did not correct it, looked upstairs, and said, "Is she up there?" ”

"Hmm." Gong Lose nodded heavily.

"I'll go up and have a look." After speaking, Zhu Zhan Dong motioned for everyone to continue to do what they had to do, and went upstairs.

On the sixth floor, next to the table in the middle of the refining room.

Dressed in loose overalls, Jing Yu, whose hair was coiled up at will, and pressed a hairpin against the back of his head, was holding a ruler and drawing a picture seriously.

She was no longer holding a brush, but a pencil.

What? How are pencils made? Is it hard? In the world of immortal cultivators, this kind of gadget is not worth mentioning at all.

"Whew!" The tip of the pen pressed against the ruler and made a sound as it swiped across the brown, yellowed hard paper.

As soon as Zhu Zhan came in, he saw Jing Yu with his back to the door, crouching in front of the table to make pictures.

A pair of wide, overall-looking trousers were covered with small metal objects.

However, this overalls trousers full of objects and tools not only failed to hide her figure, but faintly highlighted the roundness.

"It's good to be roughly like this here, but when refining it specifically, you still have to determine something more accurate, and the divine consciousness docking can understand each other's thoughts......"

Jing Yu said, frowned, and then said: "But if the machine tool is to be manufactured, listen to Your Majesty, it needs to be operated so that ordinary people can understand it......"

"Without a clear specific size, it is very difficult to use the machine."

She has already started to design and manufacture machine drawings for various parts of the heater.

At this time, Jing Yu didn't notice at all that a figure had come behind her, and suddenly, a pair of long arms directly wrapped around her waist.

"Who?!" The sudden arrival suddenly made Jing Yu tremble, and almost instantly, the terrifying ice spirit power swayed.

An arm-thick ice spike coiled up from her shoulder, and was about to poke down towards Zhu Zhanyuan's eyebrows.

Hey, this girl is a little ruthless! Zhu Zhan exclaimed, his divine sense rolled lightly, and he destroyed the ice hammer, and said at the same time: "Xiao Yu, it's me." ”

Hearing the familiar voice, Jing Yu's body trembled slightly, then turned around directly, looked at Zhu Zhan Rong in surprise, and said, "Zhan Yuan, you're back?!" ”

"Yes, I'm back, I was almost killed by you." Zhu Zhan Yan smiled and let go of her waist and patted the ice ballast that fell on her clothes.

"Hmph." Jing Yu snorted lightly and said, "Who let you suddenly appear to scare me, you deserve it." As he spoke, he also leaned forward to help Zhu Zhanyuan pat off the ice slag on his shoulder.

"Shhh Zhu Zhan took advantage of the situation to put his chin on Jing Yu's shoulder, sniffed deeply, and leaned close to his ear and said, "Incense!" ”

Feeling the heat coming from his neck, as well as the teasing words in his ear, Jing Yu's face suddenly turned red, and at the same time, his heart couldn't help but itch.

"Ahh Suddenly, Jing Yu let out an exclamation, but found that the whole person had been hugged by Zhu Zhandong, and her hands almost subconsciously wrapped around Zhu Zhandong's neck.

"You, don't mess around, this is the Refining Pavilion......" Jing Yu raised his eyes to look at Zhu Zhandong, his big watery eyes were full of timidity.

Zhu Zhan didn't care about this, he had been holding back for more than a year.

He's had enough!

I don't know how long it has been, the sky is faintly white, and it is already early in the morning.

Zhu Zhan Rong casually put on a thin undershirt, glanced at Jing Yu who was sleeping on the couch, waved his hand to lay a prohibition, and got up and walked out of the pavilion master's room.

This time, Jing Yu did not insist on the candles in the cave room, but half-pushed and half-pushed, perhaps because he hadn't seen him for more than a year, so he let Zhu Zhan do it.

Zhu Zhandong, who was satisfied, came to the front hall, and after taking a big sip of icy spiritual tea, he only felt refreshed, "Start working!" ”

Came to the refining room, picked up a stack of drawings that Jing Yu had planned before, and after writing them all down, Zhu Zhan took out the refining materials, and then began refining.

"The first thing to be refined is to make the spiritual machine tool of the cylinder......"

“……”

In a flash, time flew by.

The time came to the seventeenth year of Yongle, in late December, and the New Year was approaching.

It was also on this day that Zheng He returned from the fifth initial Western Ocean, and at the same time brought back many overseas envoys.

For a while, the whole capital was not lively.

After two months, Zhu Zhan Rong alone refined ten sets of spiritual machine tools for manufacturing hot gas engines, of course, spiritual machine tools are not comparable to those in later generations.

A machine tool, under the operation of the machine spirit, can produce several parts at the same time.

A hot gas machine can be assembled and used with parts processed by three machine tools.

After that, Zhu Zhan Rong sorted out the method of refining spiritual weapons into codex notes, broke them, kneaded them, and fed them to the refiners in the Refining Pavilion.

So that they can also refine!

Of course, the refiners of the Refining Pavilion, who are not cultivators who refine qi and transform gods, will be very difficult in refining spiritual weapons, so Zhu Zhan will let them be in groups of three or five.

In the future, the Refining Pavilion will no longer be responsible for refining complex and inefficient precision hot gas engine parts, they are mainly responsible for refining spiritual machine tools.

After testing, under the operation of the spiritual weapon, a set of spiritual machine tools can produce three hot gas engines in one day as long as the materials are sufficient.

Of course, the premise is that the spiritual machine tool must have enough spiritual energy supply!

The upper limit of the machine spirit's work time is about seven days, after which the machine spirit will have to recover its spiritual power before it can continue to work.

Later, in order to improve it, it was changed to a more convenient spiritual machine tool, and Zhu Zhanyuan also added a spirit gathering array to the spiritual machine tool.

In this way, the spirit machine tool can not only use spirit stones, but also use the spirit gathering array to absorb the spiritual energy, so that the work cycle of the spirit machine tool is extended again.

A spiritual machine tool can last for half a month.

Of course, this is also the upper limit of the machine spirit, after all, the machine spirit is thoughtful, and it can't just be let work without rest.

Once the life cycle is exceeded, and the machine spirit is forcibly allowed to work, then it is not impossible to either strike, or the machine spirit will directly manipulate the machine tool to attack humans.

But this is an inevitable problem, so we can only ask that after these spiritual machine tools enter the people, they will be strictly controlled. After that, it is possible to set up a supervision department for the use of factories to supervise some black-hearted factories.

After that, Zhu Zhan Feng refined more than ten spiritual weapons that could refine more than ten pills that could be used to manufacture pills in batches.

For a while, the manpower of the Dan Pavilion and the Refining Pavilion was completely liberated.

The people of the Dan Pavilion can concentrate on developing the Dan recipe and trying new pills, and the people of the Refining Pavilion can also delve into new machinery.

It's the end of the year, and everyone is idle.

It only takes place next year, when the machine will be fully operational.

Heat-fired engines are then produced, and finally the combination of horses, wheels, and farming implements that have been improved can be put into use.

"Next year, Daming will completely enter the era of rapid development, and then the era of cultivating immortals will really come!"

Zhu Zhan walked on the snow, thinking about things, and came to the outside of the Wuying Palace.

As soon as he walked to the door, he heard the old man's hearty laughter coming from afar, and then Liu Yongcheng hurriedly trotted up to meet him and said:

"Imperial grandson, Ma Bao is back, and the emperor is listening to his report in the palace."

Ma Bao? Zheng He, the famous eunuch of the three guarantees? Thinking about it, Zhu Zhan was also interested in this historical celebrity who appeared in textbooks in later generations.
