Although it was really a bit reluctant to rely on the energy of a three-star magic core to refine iron, Cao Yanchao finally decided to fight it.

Because according to Cao Yanchao's idea, they are idle anyway, so it's better to give it a try, maybe they will succeed?

Even if it doesn't work, then when they go back, they just have to think of another way.

After all, the worst possible outcome now is to postpone the ironmaking plan until a few years later.

After making up his mind, Cao Yanchao began to work hard, he first lit a flame on the top of the stove, and then threw the blazing flame into the empty stove.

Next, the reed rods and various dry weed debris were added to the stove to ignite the fire.

Then, the flames in the stove slowly burned more and more, and in the middle, Cao Yanchao continued to add materials to the stove.

and shouted at Cao Yandong, who was looking at Cao Yanqiu blankly.

"Xiao Dongzi, hurry up and fan the wind!"

After hearing this, Cao Yandong immediately took action, he quickly ran to the back of the stove, in front of an opening specially used to supply air, and then picked up the prepared big leaves and fanned the wind hard

With the help of fresh air, the fire is even more vigorous.

It burned like this, and it burned for nearly an hour.

Look, now the entire outer wall of the stove has been burned by the flames to a slight redden.

And Cao Yanchao, who was very satisfied with this, turned his head and said to Cao Yanqiu.

"The fire is almost over now, shouldn't you take out the magic core in your hand?"

Unexpectedly, this time Cao Yanqiu didn't say anything more, she happily took off a necklace made of unknown animal skins from her neck.

On the top of the necklace, there was a magic core that emitted red light, and then she handed this magic core to Cao Yanchao.

When he took over the red magic core that still had a faint body temperature, Cao Yanchao couldn't help but observe it curiously.

It turned out that it was a stone that glowed red, or that it was actually a red crystal.

And after studying the red magic core for a while, he found that from the inside of this red magic core, there was an inexplicable energy, which was constantly churning and agitating inside the magic core, as if it might explode at any time?

"Xiaoqiu, how should I use this thing?"

As a result, after thinking about it for a while, Cao Yanqiu said with some reluctance.

"The simplest way to use it is that you throw this magic core directly into the burning furnace, and the energy in the magic core will naturally be activated by the burning flame. ”

After hearing this, Cao Yanchao couldn't help but be stunned?

"No, if that's the case, won't your demon core be burned as well?"

didn't think about Cao Yanqiu, and said with a reasonable face.

"If it's ruined, it's ruined! Isn't it just a three-star magic core, and you can pay me another one in the future?"

Saying this, Cao Yanchao was stunned again?

So, Cao Yanchao couldn't help but say a little angrily.

"But didn't you say that magic cores can be reused?"

Cao Yanqiu also realized that Cao Yanchao was already angry, so she stopped teasing Cao Yanchao.

"As I said, that's the easiest way to use it.

In addition, of course, there are other methods, such as holding the magic core in one hand and a stone in the other, and then slamming the two together so that the flames in the magic core can be activated. ”

Cao Yanchao heard that his head was full of black lines, wouldn't that become a flamethrower?

This damn Cao Yanqiu actually dares to play with it like this, it is really, only women are difficult to raise!

It's just that in this way, Cao Yanchao worked hard to build a stove.

Isn't it just an ornament?

What's even more odious is that this damn Cao Yanqiu actually watched them work stupidly for most of the day, but only now did he say this way.

This is really too tricky.

Cao Yanchao, who was about to have a seizure on the spot, finally calmed down.

After all, now he has no other way, so he has no choice but to climb up, built in advance next to the stove, specially used to add fuel ladder.

However, as soon as he climbed to the top of the stove, Cao Yanchao found that he could not get close to the feeding port.

It turned out that the fire in the stove had been completely up, and the flames were blazing, making it impossible for people to get close to it.

Therefore, Cao Yanchao could not get close to the position of the furnace mouth.

Although Cao Jiangjun was very clever when he built the stove, he cleverly built two openings, one large one was specially used to put various materials, and the other small one was specially used to discharge exhaust gases.

However, due to Cao Yanchao's lack of practical operating experience, there is a big shortcoming in the design of his stove.

That is, when the fire is too big, it is easy to have the phenomenon of flame rolling.

And now the fire has become this terrible appearance, the raging flame has burned to the position of the discharge port.

Facing this raging flame, Cao Yanchao couldn't get close at all.

However, after hesitating for a while, Cao Yanchao was ready, and today was destined to fail, and then he shouted loudly.

"Xiaoqiu, can you give me the wooden basket on your left?"

Cao Yanqiu, who was originally watching the excitement from the sidelines, couldn't help but be stunned for a moment after hearing this, and then she reacted, this should be re-accepting her?

Sure enough, she couldn't bear the magic core, and she couldn't trap the wolf! Although Cao Yanqiu was very proud in her heart, she still immediately picked up a wooden basket filled with a large amount of gravel, and then handed it to Cao Yanchao.

Cao Yanchao carefully checked the gravel in the wooden basket and confirmed that they should be fragments of iron ore, so he poured a whole basket of gravel into the discharge port.

In just an instant, the flames that were still burning were suddenly crushed by the poured rubble.

As a result, the current Cao Yanchao began to worry about the gravel again, whether it was poured too much, and if the flames that were finally burned were extinguished, wouldn't it be a big loss?

So Cao Yanchao had no choice but to shout loudly again.

"Xiao Dongzi, the wind is not strong enough!

As a result, Cao Yandong, who had been fanning the fan hard for a long time, had no choice but to grit his teeth and continue to send air to the stove.

And as it continued, fresh air was fanned into the stove by Cao Yandong.

The flame that was almost extinguished before was once again burning under the action of a large amount of air.

Seeing that the fire in the stove was getting stronger and stronger, Cao Yanchao did not relax a little, and his face was solemn.

Because, in order to achieve the current combustion effect, Cao Yanchao has put all the fuel into the stove.

However, the iron ore that Cao Yandong poured into it just now began to turn a little red, and there was still a considerable distance before it was completely burned by the flames!

In desperation, Cao Yanchao had no choice but to put all his hopes on Cao Yanqiu's magic core.

So, Cao Yanchao slowly picked up Cao Yanqiu's magic core, and took out a piece of flint from Zhang Xiaohua from the cup.

Then, he slammed the two together.

Sure enough, the next moment, the restless energy that had been hidden in the demon core began to come alive.

But it was not what Cao Yanchao thought, and there was no flame ejected from the demon core.

On the contrary, after colliding with the flint, the demon core began to get hotter and hotter, but fortunately, Cao Yanchao's reaction was quite fast, and after he was stunned for a while, he threw the demon core that had entered an active state into the stove of the stove.

At this moment, it was as if a drop of water had been added to the oil pot, and suddenly the entire stove was boiling, and the flames kept rising.

In addition, Cao Yandong worked hard to fan the wind.

The whole stove became restless, like an active volcano that could erupt at any moment.

Cao Yanchao was so frightened that he suddenly fell from the top of the stove.

Fortunately, the stairs of this stove are not very high, otherwise Cao Yanchao would really have to fall out.

And looking at Cao Yanchao's embarrassed appearance, Cao Yanqiu on the side suddenly laughed without any image.

"Ha, haha, hahaha, I'm laughing to death. ”

At this time, Cao Yanchao didn't know Cao Yanqiu, he was simply playing with him, maybe the magic core really had other ways to use it, but it definitely didn't include the method of hitting with flint.

Immediately exploded Cao Yanchao, he looked at Cao Yanqiu angrily, if it weren't for her being a little girl, Cao Yanchao couldn't wait to rush up and beat her immediately.

Well, in fact, the thing is not as Cao Yanchao thought, hitting the magic core with flint, it is indeed a use of the magic core, but ordinary people will not do this.

This is the same as using flint to smash gunpowder directly, which is very dangerous.

The preferred method is to throw the core directly into the burning flame.

Under the stimulation of the flames, the magic core can naturally be used to make fire, and there is no need to use flint to hit the magic core.

However, after seeing Cao Yanchao's murderous gaze, Cao Yanqiu immediately confessed, so she carefully explained.

"Xiao Chao, don't blame me for this, it's completely because you think too much, the magic core itself is the essence left after the death of a high-level demonic beast, how can it be burned by ordinary flames?"

Cao Yanchao was stunned for a moment, and finally his anger gradually disappeared, after all, he was not a real child, but an adult, how could he be with a little girl?

And looking at the burning stove that was getting more and more prosperous, Cao Yanchao could only get up from the floor helplessly, and then he patted the dust on his body while asking Cao Yanqiu.

"Then do you know how long the flame in the demon core can burn, and how high the temperature of this flame can be?"

As a result, Cao Yanqiu's eyes were dark, she just knew that the flame of the demon core was enough to burn an ordinary person into ashes, and it was the kind that didn't even have scum left, if she encountered it, when she encountered a non-fire-based three-star demonic beast, she could directly burn them alive.

But what exactly is the temperature of the flame? What is that, she doesn't understand at all?

"What's the temperature? I don't know, but if you want to burn someone, it's no problem at all, and it's the kind that doesn't have any slag left, oh, dear!

As for how long it can be burned, then I don't even know, but the one I used for the longest time took more than two hours!"

Saying this, Cao Yanchao secretly swore in his heart that he would stay away from this ignorant woman in the future.

Cao Yanchao originally just wanted to find a material to burn the fire, but this stupid woman directly gave him a nuclear fuel, isn't this a sneer?

This stupid woman is really not enough to succeed and more than to lose!

However, he looked at the stove and then at the direction where his house was.

At this time, Cao Yanchao couldn't help but be glad that when Cao Jiangjun was building the furnace, he originally wanted to build it close to home, but due to his strong request, the stove for burning the fire was built next to the moat.

This place is at least more than 100 meters away from Cao Yanchao's home, and it should not be affected by the flames.

Even if the stove was burning, because he couldn't withstand the flames in the demon core, he was burned and exploded, and he didn't have to worry about hurting the innocent.

Of course, the question now is, should we let the flames in the demon core continue to burn?

If, if you want to control the fire, you only need to ask Cao Yandong to stop fanning, then there is no fresh air, and the flames in the stove will naturally be slowly extinguished.

Of course, the final answer is to continue to burn!

Anyway, the worst result is that the iron can't be smelted, and even the stove is burned into a pile of scum by the flames in the demon core.

Of course, prevention work also needs to be done.

So, Cao Yanchao unceremoniously pulled Cao Yanqiu with him, came to the riverbank, and the two began to dig a ditch.

That's right, this is Cao Yanchao's last resort.

Once the whole stove was completely burning, he dug the embankment and let in the raging water.

Then, you can use the raging river water to completely extinguish the stove that has gone out of control.

Of course, this is just a last resort, and Cao Yanchao will not use this method until the last moment.

After all, Cao Yanchao was not sure, and asked Cao Jiangjun to help him build a stove again.

Fortunately, the entire part of the diversion ditch had been dug almost completely, so it didn't take long for Cao Yanchao and Cao Yanqiu to dig the remaining part of the diversion ditch.

And Cao Yanqiu, who was tired and half dead, could only look at Cao Yanchao with hatred, she naturally knew that Cao Yanchao was deliberately retaliating against her to vent her personal anger, but she couldn't say anything.

Of course, Cao Yanqiu can also walk away, but it is impossible.

Let's not mention, in the stove where the fire is burning, there is also Cao Yanqiu's father, who gave her the magic core for protection, so why did she go back to Cao Yanchao and Cao Yandong?

Naturally, she wants to promote the dish of barbecued river fish to the whole village!

If you leave now, wouldn't it mean that everything before was in vain?

Just when the two were speechless for each other, Cao Yandong, who had been fanning the wind hard, suddenly shouted loudly.

"Oh no, it's water, it's water!"

It turned out that just as Cao Yandong was fanning the wind hard, a violent northwest wind suddenly blew from behind him.

This violent northwest wind made Cao Yandong, who was fanning the wind hard, feel refreshed.

But when he came back to his senses, the whole stove was already burning.

Originally, the stove that had been specially treated by Cao Jiangjun would not be ignited so easily.

But first, the burning effect of the demon core was too amazing, far beyond Cao Yanchao's expectations, and second, this northwest wind came at an inopportune time.

Add these two together, and in a short period of effort, the entire stove will be completely burned.

When they saw that the stove had completely turned into a burning torch, Cao Yanchao and Cao Yanqiu couldn't help but be stunned.

However, Cao Yanchao was the first to react quickly, and he immediately shouted at Cao Yandong, who was still standing in a daze.

"Run, don't stand still!?"

As a result, on the one hand, Cao Yandong fanned the wind for too long, which caused some stiffness in his whole body, and on the other hand, it may be because he was too nervous, he actually habitually began to be in a daze again, just standing in place, not moving.

Seeing this situation, Cao Yanchao suddenly felt angry and anxious, and in desperation, he had no choice but to rush forward.

However, just in case, he still activated, and the power word in the Nine Realms mantra rushed towards Cao Yandong quickly.

This is the result of Cao Yanchao's daily hard practice for the past half of the year!

Therefore, after just a few seconds, Cao Yanchao had already rushed in front of Cao Yandong.

Seeing Cao Yandong who stayed in place, Cao Yanchao didn't think too much.

Directly picked up Cao Yandong, who was still in a daze, pulled his legs and ran in the direction of the river.

No way, who knew that all of a sudden, a northwest wind would blow?

In normal times, the southeast wind blows in Montenegro Village.

Fortunately, this is still some distance away from Cao Yanchao's home, so he doesn't have to worry that this huge flame will burn into his home.

Now he needs to worry, but he and Cao Yanqiu, Cao Yandong, will be burned alive by the flames that are rolled back.

After all, Cao Yanqiu said that the flames in this demon core can burn people to ashes, and they are still the kind that will not even leave the scum.

As a result, before he could run a few steps, Cao Yanchao saw a stream of river water, surging along the diversion ditch.

Obviously, after Cao Yanqiu came to his senses, he immediately dug up the river embankment and led the turbulent river water over.

Cao Yanchao, who was at this time, didn't think too much, he still hugged Cao Yandong and continued to run towards the place where Cao Yanqiu was.

The most important thing now is to get away from the stove that is burning more and more, and the farther away from it, the better!

However, in the end, Cao Yanchao didn't run far, he only heard an earth-shattering loud noise.

"Boom !!"

Then, Cao Yanchao, who was desperately running away with Cao Yandong in his arms, only felt a whirlwind of the world.

As for what happened after that, Cao Yanchao didn't know at all.

......
