Tiangong Palace.

As its name suggests, "Heavenly Craftsman", the institution is equivalent to a large factory, and its responsibility is to manufacture all kinds of mystical tools, magic tools, and gray crystal machinery.

Of course.

Since the gray crystal machinery belongs to civil machinery, Tiangongdian only manufactures the core object "spirit crystal disk", and the rest of the parts are responsible for the private factory.

At this moment.

A gray-haired master craftsman put down the letterhead in his hand and kept muttering:

"'Including the Xuanfa, the change of everything is essentially the transformation of energy', although the statement of Special Envoy Cheng is strange, it is not unreasonable to think about it......

It's right next to it.

A middle-aged craftsman is carving a spirit crystal disk.

He insisted on a delicate carving knife, and with a far more flexible than ordinary people, he drew a spiritual pattern, and then tested it with a magic tool, and then continued to carve the next spiritual pattern.

And if the master wins the bet, there is a small probability that the salted fish will not be able to turn over.

The middle-aged craftsman seemed to be attentive, but from the flickering eyes of his people from time to time, it could be judged that he was listening to the master's words distractedly.

The middle-aged craftsman opened his mouth, but finally said nothing.

The middle-aged craftsman chimed in: "That's indeed an advantage. ”

The middle-aged craftsman was dumbfounded.

The little craftsman suddenly changed the subject: "In the letter just sent, Special Envoy Cheng envisioned a very powerful flying weapon called the 'bomber'. ”

The little craftsman shook the letter in his hand, and said: "The internal combustion engine envisioned by Special Envoy Cheng is not refined brown oil as fuel, and brown oil is not refined from stone fruits.

"The core essence of the internal combustion engine is to convert the heat energy of fuel combustion into kinetic energy, which can also be regarded as a kind of occult ...... in a sense."

The middle-aged craftsman's smile froze instantly.

The master craftsman whispered the contents of the letter again.

The middle-aged craftsman sat up slightly straight, revealing a listening look.

It's worth the gamble!

The little craftsman gushed: "Special Envoy Cheng said that it was an inspiration that came to me by chance when I was playing with paper airplanes when I was a child.

"Xuanjing does contain relatively little source energy, but that thing has always been a tight supply in the Xuangong, and forty percent of Xuanzhou has no Luya.

Half an hour has passed.

The middle-aged craftsman nodded heavily: "If you really can't make an internal combustion engine, it is indeed a feasible solution." ”

The little craftsman looked annoyed: "Liang Ming, if he steps on the horse again, wait for labor and management to make a prototype of the internal combustion engine, and let him start the machine with a big sparrow!" ”

"The envoy villain called that kind of plane a 'bomber,' and that kind of warfare was not the 'carpet bombing' I envisioned."

When the middle-aged craftsman heard this, he laughed out loud: "Isn't this horse riding nonsense?" ”

The middle-aged craftsman had the courage to retort: "Master, you are brain-dead!" ”

The middle-aged craftsman seemed to think that it was a wonderful joke, so he simply stopped carving and laughed: "That's so boring!" ”

"The Xuangong belongs to a hundred and less spiritual realms, there are wastelands everywhere, and the stone fruit trees are not too much if they want to plant less, and they can't be picked every year, and the cost can't be very high."

The middle-aged craftsman took the letter and read it carefully.

"But you were squeezed out like that in the Tiangong Palace, a dignified little craftsman, you actually make gray crystal machinery every day, Envoy Cheng can afford to play, but you really can play."

I felt in my heart that that sentence was unreasonable!

The little craftsman was silent for a few seconds before he hurriedly spoke: "In a letter, Special Envoy Cheng wrote such a sentence......

The little craftsman scolded politely: "What Special Envoy Cheng said is obviously not insightful, he just understands it when he has the brain, but he doesn't have the face to laugh at Special Envoy Cheng." ”

I paused and said, "Anyway, it's not a small street, so there's nothing you can't lose?" ”

The master replied, "You can't change it!" ”

It's not just that the salted fish turns over, and it is a problem to become the head of the Tiangong Palace, and even it is impossible to leave a name in history.

That's the little truth.

"If you really build bombers, you need Xuanzhou to fly Luya, and special people can also play a huge role in the war.

It's also a heart-piercing word.

"The essence of the way of the Xuanshi is to enhance one's own energy and turn oneself into a humanoid 'source crystal', and the Xuanfa is to transform one's own power into other powers, such as the heat energy of the fire Xuanfa.

The middle-aged craftsman was finally moved, and his eyes showed a blazing coldness: "Master, that is indeed a genius idea, you can't follow Special Envoy Cheng to give it a try." ”

The little craftsman glared at the apprentice: "It's a little way!" Those formulas contain the principles of the trail, and he only half-understands them when he steps on a horse. ”

After a while.

I immediately threw over a letter: "These formulas are out there, and your arithmetic skills are still wrong, so you should be able to understand them." ”

"Even the highest, cheapest gray crystals are more expensive than special people can afford, and that limits their application to a minimum.

The little craftsman suddenly sighed: "What Special Envoy Cheng said is wrong, in addition to the lightness of the gray crystal machinery, another small problem is not that the cost is too low.

The middle-aged craftsman felt that the master had gone mad, so he couldn't help but nag: "Envoy Cheng is a real genius, and dissolving a Xuan Seal can trigger a spiritual tide."

In case it succeeds.

The middle-aged craftsman asked curiously, "What does 'Xiaopu Street' mean?" ”

The middle-aged craftsman agreed with that view: "The cheapest gray crystal lamp can only be used by poor families, and a small number of civilians can only use oil lamps." ”

The little craftsman's tone became excited: "In the letter, the envoy villain has come up with an astonishing plan, and thousands of metal planes must have been built.

The ugly picture of "the finch turning the machine" popped out of my mind, and I immediately shuddered, and calmly admitted my mistake: "Master, you are wrong!" ”

The guy couldn't help but grin: "Then if you say it, you must light a barrel of brown oil, is it equivalent to casting a fire system mystic?" ”

"Each plane carried two 'Spirit Flame Xuanbing', and Pang Xiao's group flew from the air to the enemy's position, and threw all the Xuanbing soldiers on the front.

The guy then asked a question: "The output power of Envoy Cheng's prototype is not small, but the size is also very small, and it is much worse than the gray crystal machine. ”

The tone of the little craftsman could not be called excited: "For a long time, due to the production of Xuanjing, the number of Xuanshi has also been limited.

The master glanced at his apprentice and explained, "It's like you." ”

The middle-aged craftsman peeked at the master and ended his honest work.

"Even if Envoy Cheng is fooling around, one is that he blows up the living hall with a big heart, and the villain of the palace master will only laugh and say that it is blown up.

The middle-aged craftsman dared to agree: "Gray crystal machinery has been regressed for tens of thousands of years, and the size is still so small." ”

For the master, even if he loses the fight, at most he will not go back to his hometown to retire, it will be slower than staying in the Tiangong Palace.

"In this way, the strength of your Wanhao clan will definitely increase and weaken very slightly."

The middle-aged craftsman nodded heavily: "It's true that there is no way at all." ”

The little craftsman shook his head: "Special Envoy Cheng proposed the concept of 'cold value', and also deduced a formula of 'cold energy to kinetic energy'. ”

The little craftsman snorted, and read the letter again.

"The envoy villain thinks that a metal plane must be built, and then an internal combustion engine must be installed to drive a propeller to make it fly."
