(Thanks to the support of Fog Food Book, Floating Life, and Zhang's Black Girl)!!

Bi Mang finally earned his own money, and he was no longer a bystander who couldn't do anything. Ruyi no longer stopped it, and Bimang swam down with joy at this time, swam around the silver ingot, and finally surrounded the silver ingot with his body.

"Yuanbao, we seem to have been robbed by my sister Ruyi, who is obsessed with money, and she won't let me sign it, just because I'm afraid that I will rob her of silver ingots!"

Yuan Bao smiled and stretched out his hand to Bi Mang's side, and Bi Mang followed Yuan Bao's hand and came back.

"Bimang, you don't have to worry, you follow Sister Ruyi when she buys things, how can she not give you points?"

Ruyi was still a little worried that Bi Mang would rob her, after all, this is different from Gu Zheng's army, or robbed from the bandits' den, a small silver coin is of great significance, marking the affirmation of their ability, especially Bi Mang. Yuan Bao only comforted Bi Mang, smiled reassuringly, and let the silver ingot disappear from the gaze of so many pairs of eyes.

"Sister Ruyi, we have finally earned money, what should we buy to celebrate?

"Bimang, don't worry, there will be, there will be anything in Ruyi City, there will be something in other places, we will definitely have Ruyi City, there will be nothing in other places, we will also have Ruyi City, there is only one unique Ruyi City in the world, my sister wants to let everyone in the world know that only Ruyi City is the best!"

Two people came from outside the door of the council hall, and the city guards outside the gate came in and said, "Ancient city lord, the things you want have been delivered, do you want them to bring them in now?"

"I forgot if they didn't come, let them bring it in!"

After the ancient city lord finished speaking, the city guard waved his hand to let a craftsman in, he held a black black thing, and after putting it down, he saluted the people in the house before leaving. Yuan Bao saw the things sent and immediately walked over, this is the stove he wanted, and the ancient city lord found someone to make it and send it in one day.

The hearth of this stove is less than a foot, and there are three legs more than a foot high below, and the total height is just over two feet, which is slightly higher than the fire where Yuan Bao grilled fish in the valley, and much lower than the stove in the room. The hearth was round, about a foot thick, and two-thirds of the way down the hearth was a baffle with a grid for ventilation, on which the stones they found could be placed.

"Yuanbao, this one is a little rougher, you see if it fits, is there anything that needs to be improved, if there is no major problem, I'll let them make you a more refined one tomorrow?"

Ruyi knew what it was and what it could be used for, so she flew into the hearth.

"Sister Ruyi, what are you doing, there is no fire in it, and besides, you don't have much meat, come out quickly!"

"Stinky Bimang, do you want to roast and eat your sister too, my sister has no meat, and she has more meat than you, hum!"

Yuan Bao didn't take out Ruyi, and Ruyi always wanted to be novel for a while. Yuan Bao's gaze left the furnace, and Bi Mang also curiously went to Ruyi's side.

"The ancient city lord, this look is already very good, I forgot one thing, I see that the stove pond in the house has a chimney, this stove can also cook in the future, only the ventilation below is not enough, it is best to have a chimney like the stove pond, I also want this kind of stove to enter thousands of households, iron seems to be bought with money, ordinary people may not be willing to spend money to buy a stove at the moment, can you change the stove in the room, the method is taught to everyone, so that ordinary people can also build a stove by themselves?"

Of course, Yuanbao wanted to use the stone they only found today for thousands of households to use, which was not only convenient, but also brought a lot of benefits to Ruyi City. The ancient city lord has only seen two small pieces, and the city lord Du doesn't know about the stone, so he is confused by the words of the ingot.

Ruyi and Bimang were not confused, Bimang whispered, and Ruyi was about to jump out of the stove.

"We want this stove from the ancient city lord, it can be put in the house, just like the house we live in now can be used, Yuanbao still wants to learn to cook, can you make another one for me? Don't do it like this, I want a shorter one, so that the legs of the stove are shorter, and the belly of the stove is bigger, so wide, but it should be longer, at least as long as Yuanbao's arm, you don't know how large our family is? Ingot has to bake several fish at a time to make us all full, ingots can bake several fish at a time, Bimang, you say we should make more stoves like that? I think at least two should be enough, Laipi Fenglei is so edible, by the way, the ancient city lord, will you ask us for money, I tell you that we don't have money, we don't have enough to share the moon that was just issued!"

The two city lords had never figured out what this furnace could do, and in their eyes the furnace was too small, and it was not ugly, but it was not practical. Bi Mang and Ruyi muttered quietly, plus Ruyi also wanted at least two longer and lower stoves, and the grilled fish made the people in this room a little itchy, and the wooden shadow in this room had eaten the fish grilled by ingots. As for the money, the ancient city lord hadn't thought about it before, because the ancient city lord hadn't eaten the grilled fish, and he didn't want to make a stove for Ruyi.

"Sister Ruyi, it turns out that you went to the mountains to eat grilled fish and didn't leave it for us, and you want me to make a stove for you, you don't need money, but it's better to exchange it for grilled fish!"

"Bimang, look at it, they must have also smelled the fragrance of Yuanbao grilled fish, or Mu Ying betrayed us, where did we get the grilled fish now? Yuanbaoguang was busy digging holes, and we didn't have grilled fish to eat today, and said that they didn't want money, obviously they just wanted to rob us, and I could exchange good things for the stove!"

Ruyi and Bimang both left the furnace, one fell on the top of the ingot's head, the other fell on the shoulders of the ingot, Ruyi's wings moved slightly, and a large four, four small and five stones flew out and fell into the hands of the ingot.

"Ancient City Lord, this is a treasure, I can exchange so many treasures for two longer stoves, right?"

The ancient city lord immediately walked over when he saw the stone that appeared. Ruyi's shrewdness made the ancient city lord have to admire, only one of the five stones she took out could see a little bit of dark blue exposed, and the other few pieces were wrapped in traces of wind erosion, Ruyi disliked the bad condition and took it out.

"Yuanbao, have you finally found this kind of stone?"

"I found them today, and I made a stove to try to see if it was good or not, so that I didn't need to burn firewood for cooking in the future. As he spoke, he placed the stones in the furnace, four small ones on the four sides, and one large one in the middle to hold down the four small stones. "This stove should be lit with firewood first, let's just do an experiment today, so we don't need to be so troublesome, just let Sister Ruyi put a fireball." ”

More than a dozen people came to the conference hall in this big room today, and at this time, they still couldn't figure out what Yuan Bao was going to do, so they all stood up and watched quietly around them.

"Sister Ruyi, it's your turn, put a fireball under the stones, don't be too strong in the fire, you won't be able to understand if you burn all these stones at once!"

"Okay, my sister loves to play with fire the most, don't worry that she won't use fire!"

Ruyi said, as if out of a bath, raised one of her wings and shook it gently. In the past, Yuanbao has always been very tightly in charge of Ruyi, including Du City Lord, most of the people here have only heard of Ruyi's fire and have not seen Ruyi's fire, and they all held back the horror in their hearts and widened their eyes. The ancient city lord is one of the few people who have seen Ruyi's fire, and the ancient city lord also likes this kind of fire that seems to have no root and no source, so he is willing to be abducted by Ruyi, but unfortunately he has never had the opportunity to try. This is not Ruyi stingy, first of all, she has no patience to set fire to the ancient city lord, and then Ruyi's fire looks beautiful, but it is by no means so fun, it can be said that in addition to Ruyi and ingots, I haven't found anyone who can help Ruyi's fire, and letting the ancient city lord get close to this kind of fire is tantamount to harming him.

From the tips of Ruyi's wings, beautiful yellow droplets of water the size of water droplets appeared. The ancient city lord couldn't resist the temptation, and wanted to reach out to catch it, but fortunately, the city lord Du had the strength of a strong man, or realized the deep danger, and grabbed the ancient city lord who wanted to move, the drop of water with almost golden light swept past the ancient city lord's hand, fluttering into the furnace, according to the requirements of the ingot, drilled under the large stone in the middle, and there was a very light explosion. It was a small fireball that ignited the dry twig, and at this moment it erupted into a fist-sized mass under the stones in the furnace, and it took a few breaths of wishful thinking to make it disappear.

Before, there was a yellow fireball illuminating the stove, which affected people's vision. After the yellow fireball disappeared, people were pleasantly surprised to find that under the large stones, through the gaps between the stones, there were flames two or two long that came out.

"It's on, Bimang, have you seen it, it's still my sister who is amazing, you can set the stone on fire!"

Hearing the smug voice, the people who were standing far away looked carefully and came closer. A few more wisps of blue flames came out of the furnace, and it didn't take long for the small stove to be filled, and the crowding of flames began to rise gradually, and some of the flames began to burst out of the furnace, and you didn't have to get so close to see the blue flames on the stove clearly. At this time, the flames were only the four small stones placed under the ingots, and the fire of the four small stones had not yet ignited the large stone in the middle.

"Yuanbao, can this stone really make fire?" The ancient city lord, who had played with fire all his life, had been conquered by the blue flame at this time, and sincerely sighed at the magic he had seen with his own eyes.

"Ancient City Lord, you are an expert in this area, is there anything abnormal about this fire?

The ancient city lord's gaze was reluctant to take his eyes off the stove, he must have thought more than ingots, maybe more than everyone here.
