The temperature inside the volcano is extremely high, and there is fire slurry everywhere, so it is impossible for any living thing to grow naturally in it. The flame fruit in the active volcano does not grow naturally, but is cultivated by someone.

It is rumored that the immortal prescription recorded in the "Chronicles of the Yi Kingdom" is the overseas immortal prescription found by Emperor Yinghuang back then. After Emperor Ying got the overseas immortal prescription, he ordered people to look for the medicine on it, and if the search was fruitless, let people plant it!

The flame fruit in the active volcano was planted by Emperor Win and was recorded in the "Yiguo Chronicles" by later generations.

Since it was planted by someone, it means that someone had entered the interior of the active volcano before, and there was a road inside, and this road happened to be found by the people who gave birth to it.

"Madam, this is the intersection of an active volcano, and we can't get in." The people from the Immortal Gate brought Gu Qiancheng to the entrance of the active volcano, pointed to a red stone gate and said.

The entrance is at the foot of the volcano, and the temperature is also very high, but it is still "cool" compared to the center of the volcano.

"Can this stone door be pushed open?" Gu Qiancheng looked at it for a long time, but he didn't see that there was a place to start with this stone gate.

This stone gate could not see the edge, it was completely integrated with the volcano, and if it weren't for the people from the Immortal Gate, she wouldn't have been able to see that it was a stone gate.

"Yes, there are numbers on it, as long as you calculate the number of opening the mechanism according to the law, you can open the stone door. Madame, look closely. "The people of the Immortal Gate were obviously journeymen, and they put on gloves, brushed off the covering on the stone façade, and showed the numbers engraved on it.

"This is a math problem, as long as you find a normal number, the stone gate will automatically go up." The numbers on the stone gate were very messy, and the people from the Immortal Gate did not explain to Gu Qiancheng the rules for finding numbers, but said, "The number on this stone gate, we have already calculated, is 13." As long as you place your hand on the number 13, the stone gate will automatically go up. Inside is also a stone door, and there are many numbers on it, and when Madame goes in, she only needs to write down the numbers inside, and we will calculate the normal number. ”

The people from the Immortal Sect said as they demonstrated to Gu Qiancheng. He only lightly put his hand on the number "13", and he heard a sound, and the stone gate, which did not even have a gap, slowly rose under their gaze, leaving a way for Gu Qiancheng, just ......

As the people of the Immortal Gate said, one meter away from the first stone gate, there is another stone gate. Although there was some distance to see the specific number on it, it was enough for them to see that the stone door inside was also engraved with numbers.

"Madam, let's go inside, we'll go in...... will die! The people of the Immortal Gate stood outside the door, not daring to take half a step in.

They tried many times, and no matter what method they used, as soon as they stepped into it, their bodies would slowly melt away, like pieces of iron thrown into a forge.

"You can't go in, can I?" The temperature under Huohuo Mountain is extremely high, and the temperature will naturally be even higher when she goes inside, although she can stand it now, but she doesn't dare to act rashly.

The people of the Immortal Gate will die as soon as they enter, what about her?

If you die here, you won't even have a person to collect the body.

"Madame, you are different, of course, we don't force Madame, Madame, you just try." The people of the Immortal Gate were not embarrassed by Gu Qiancheng, and they were not afraid that Gu Qiancheng would find a way to trap them if they knew that they couldn't enter.

The numbers on the stone gate require a huge amount of calculation, and it is not something that Gu Qiancheng can solve alone, as long as Gu Qiancheng wants the Flame Fruit, he has to rely on them.

"I hope you didn't lie to me." Even if the people from the Immortal Sect don't say it, Gu Qiancheng has to try, otherwise she won't come in vain this time.

Taking a breath secretly, Gu Qiancheng made mental preparations for a long time, then closed his eyes and took a step forward.

Go inside...... It was noticeably warmer and the air thinner, but it was still within the range she could bear, and although her skin was burning, there was no pain from being burned.

It seems like it really can!

Gu Qiancheng opened his eyes and took another step forward, still fine, but he felt that the temperature was higher.

"It's finished." The people of the Immortal Gate, when they saw this scene outside, their eyes lit up one by one.

Gu Qiancheng stopped and turned his head to look at them, "It's only taken two steps, you're too happy." She had taken two small steps, and she had to take two more steps to get to the second stone wall.

"Madam, we can't even take a step in, don't believe you......" In order to prove to Gu Qiancheng, the people from the Changshengmen walked in with the pen and ink of special paper, but with just one step, Gu Qiancheng saw that his exposed skin instantly blistered and festered, as if it was burned by high temperature.

"How so?" It was a little stuffy inside, but she could still bear it. It doesn't make sense that as soon as the people from the Immortal Gate come in, they will be burned.

"That's it, so we can't get in." The people from the Immortal Sect smiled bitterly, and after handing the pen and paper to Gu Qiancheng, they quickly retreated, "Madam, you can come out after you copy the numbers, and we will calculate it." ”

The Immortal Gate was obviously prepared, and in order to calculate the numbers on the stone gate, they brought all the people in the gate who were proficient in magic numbers.

"Okay, I'll copy it." Gu Qiancheng saw that the people from the Immortal Sect did not lie to her, and nodded sternly.

At this time, don't fight in the nest, if you don't go into the place where the flame fruit is planted, the people of the Immortal Sect will never hurt her by half a point.

The numbers on the first stone door are all double digits, and the numbers on the third stone door are all three digits, and it looks like there are more of them.

Gu Qiancheng was copying, thinking about what principle these numbers were combined according to and how they were calculated, but when she finished copying, she didn't see a single reason.

"I'm done." It was too complicated, Gu Qiancheng found that his brain capacity was not enough, so he had to come out with the copied numbers.

"Let's do the math." Outside, the people of the Immortal Gate were already ready, and they just waited for Gu Qiancheng to come up with the numbers and start calculating.

This is a very huge project, which requires a large amount of calculations, and it took two hours for Rao is people who are proficient in the number of techniques in the Immortal Sect to work out a number.

"327, madam, press this number, and you can open it." Two hours later, the eyes of the person who was proficient in mathematics were red, and he reported the number to Gu Qiancheng to know.

"Okay." Gu Qiancheng didn't understand, but she saw that those people had counted countless times, and the numbers they got were all 327, so she believed it.

With a pen and paper in advance, Gu Qiancheng walked inside, pressed his left hand on the number 327, and after a while, the stone gate made a muffled sound and slowly rose.

There is nothing to open the second stone door, because there is another stone door behind it, and the number on this stone door is four digits.

Obviously, the third stone gate is more computationally intensive!
