On the Chuang Tzu of the imperial villa, on the original wasteland, several smoke dragons rise from the ground, and several mud kilns are burning day and night.


    In five mud kilns firing colored glass, five masters made glass glue, burned it, burned it again and again, and they didn''t want to stop blowing until their cheeks were sore.


    Tang Hao paid them twice as much as the kiln workers. If he didn''t do his best, he really didn''t deserve the money.


    In addition, these are colored glasses sold in the Imperial City, which are better in workmanship than those in Yangzhou.


    The kiln workers who made glass kept improving, which also made these strange craftsmen skilled.


    Who would have thought that people who could not even afford the glass sol could blow out some patterns at will.


    The kiln is not idle, and so is Tang Hao.


    Carts of charcoal were sent over, and the open space had been piled into a hill.


    This area is divided into wine making, where there is a piece of fried tea, which is divided around. There is even a small place left in such a large imperial villa.


    Tang Hao had to temporarily requisition several official kilns to burn cement.


    The next step is to dispose of the charcoal by yourself so that they can be better stored.


    They ordered the people to crush the coal with a roller, then use some clay clay, and keep stirring until the granular charcoal became fine.


    Sure enough, this charcoal is a valuable thing known to these dignitaries in the imperial palace.


    It is said that the charcoal in the imperial palace is poisonous, but these poor masons know nothing about the charcoal, and even they can''t give their names.


    The official who minted money sent a strange thing.


    At the bottom is a cylindrical cylinder, about an inch high. An iron pipe is welded on it. The T-shaped slender handle is placed at the front end, which can move and ring.


    He handed it to Tang Hao, who was beside the coal, and the official asked curiously.


    "What is this?"


    Tang Hao, with dark hands, took the borrowed thing and smiled mysteriously.


    "This is a good thing. It can solve Datang''s fuel for cooking in the future."


    Staring at the strange tube, the officials didn''t believe it. No matter how you look at it, it doesn''t look as powerful as this.


    The poor go into the mountains to cut firewood, chop some logs and branches, and dry them to be fuel.


    When burning, smoke billowed into the sky. If you encounter wet wood that has not yet dried out and windy weather, the whole house is often filled with green smoke, choking people cough and tears.


    For rich families, they pay more attention to it.


    Charcoal, is the best choice, easy to store, and do not have to endure the crime of smoke and fog.


    These two fuels are the most convenient fuels inherited by our ancestors for thousands of years.


    Looking at the iron pipe in front of him, the eyes of the officials were very confused.


    Tang Hao''s novelty has not been seen once or twice by their Foundry Division, but this is a special case. It''s really weird!


    "Can such a big object improve our Datang fuel?"


    "Why do I sound so mysterious?"


    Tang Hao didn''t say much. The thing in his hand was nothing else. It was the hand briquette machine commonly used in the countryside when he was a child.


    At that time, he was still young and couldn''t stop playing.


    Now, in this different time and space, I feel very kind to meet this object again.


    It''s quite cool to start with, but there''s warmth in my heart. I can even feel the taste of childhood.


    Lift the handle and drop it into the reconciled cinder, which is neither light nor heavy.


    The T-bar standing on the handle rises higher and higher with the next blow.


    "Don''t underestimate this thing."


    "The coal made from this thing is regular and flat, unique in shape, and more convenient to store than charcoal!"


    "And ah, in winter, when heating and boiling water, charcoal has to be poured in baskets. Two pieces of this thing can manage one night!"


    The officials and the masons around were stunned.


    Two for a night?


    Can this thing really save so much?


    You know, the charcoal in Chang''an City, but with the cold weather, the price soared.


    Even ordinary rich children don''t burn from the beginning of winter to the end of winter. After all, it''s too expensive!


    If this thing is as magical as Tang Hao said, can it really change the fuel problem of Datang?


    There was a trace of movement on the official''s face. After all, officials like him could only burn the charcoal in the cold winter.


    Looking at Tang Hao pressing down the crossbar, a cylindrical coal block with several small holes gradually appeared in front of him.


    "This... This is it. If you burn two pieces, you can manage it all night?"


    "Lord, don''t deceive me!"


    Tang Hao turned around and looked at several people squatting on the ground to study honeycomb briquette.


    "Whether to cheat or not. After a few days, the coal will be completely dry and you''ll know as soon as you try!"


    As soon as the voice fell, he saw that the official stretched out his hand to hold up the coal and hurriedly stopped it.


    "Hey, hey! It hasn''t been dried and can''t be touched!"


    "So precious? Marquis... Discuss something... The one in your hand... That... Can you lend it to me?"


    "It''s for the exclusive use of Tang mansion. I won''t lend it out for the time being. If you want to borrow it, give me 300 honeycomb briquettes first."


    "Is that true? Yes! I''ll start counting now!"
