At this moment, Song Yufei could conclude that she was indeed very lucky. What was beating inside the black ice was the ice heart that Zikun mentioned, and it was still its true form. However, there was no way to take out the ice heart, at least using brute force was of no use.

of.

Bing Xin can't move within Xuan Bing, which saves a lot of trouble. Now it's just visible but not tangible. There will always be a way.

In the following time, Song Yufei used the power of thunder to attack, put her palm on the Xuan Bing to release Thunder Palm, slashed with the colorful sword, and so on. There was no damage to the Xuan Bing for ten thousand years, and she was so tired that she didn't even sweat profusely.

After a little improvement, just when he was about to give up, the torch stuck on the rock wall fell down and rolled to the side of Xuan Bing. The ice heart in Xuan Bing immediately disappeared without a trace, but the torch was still close to Xuan Bing.

It's burning, and it's burning more and more vigorously.

Song Yufei was startled and grabbed the torch. As soon as the flame left the Xuan Bing, it immediately returned to its original state. When she saw a layer of white frost faintly floating on the surface of the Xuan Bing, it looked like it was about to melt.

Song Yufei immediately realized that this "thousand-year black ice" was not actually ice, but an extremely cold substance with a very high hardness. The solid burning in the torch did not know what kind of substance it was. During the burning process

It was a pity that I didn't learn chemistry well about the reaction with this "black ice". Although I had some fill-ins after opening my mind, I still hadn't figured out what these two substances were for a while.

Forget it, never mind it, as long as it works, Song Yufei secretly rejoiced, holding the torch in her hand and rubbing it against the mysterious ice, the flames of the torch burst out again, slowly eroding the "black ice".

Zikun clapped his hands beside him and shouted: "I didn't expect that these torches have such a good effect. I will bring two more."

Song Yufei nodded and continued to melt the "Xuan Bing". Zi Kun took two of them, and the two practiced together, and their speed improved a lot.

Song Yufei said to Zikun: "Brother Kun, this torch may hurt Bing Xin. Let's dig out the whole piece first, and then slowly peel Bing Xin out."

Zikun smiled and said: "Of course, brother Yufei, I would say you are lucky, tsk tsk, now, the effect of your body tempering must be incredible!"

Song Yufei smiled and said nothing and continued her work.

Although the substance in the torch had an effect on the "mysterious ice", the two of them still worked hard for two days to wrap the ice heart in a piece of black ice and take out the ice heart, and then took another three days to carefully take out the ice heart.

The ice heart was not big, only the size of a duck egg. It was shaped like a human heart. It was beating constantly and releasing cold energy. It was impossible to take it directly. In the end, Zikun wrapped it with rocks.

, wrapped four layers in a row, there is still a layer of frost on the outside of the rock, but at least it can be taken.

Zikun was actually much more excited than Song Yufei when Bing Xin got it. You must know that this is what many people dream of, so how could he not be happy now that he had got it.

The two packed up and planned to leave, then went around to the east side of Tiandu Mountain to see the fire gall. Before leaving, Song Yufei went to Pangu's spiritual tablet to pay homage before leaving with Zikun.

The east side of Mount Tien Duk is an active volcano, and the temperature has also increased. The two of them were careful while walking, but fortunately, at least they did not encounter any strange beasts like the Snow Rabbit, as if this area is not suitable for survival.

, not even a single weed can be seen on the mountain.

The two of them got hotter and hotter as they walked, and soon they were sweating profusely. Fortunately, the ice core wrapped in the rock was still releasing cold air, which had a good cooling effect. Not far away, a river of magma could be seen.

The water slowly flowed down from the top of the mountain, and the surrounding land was scorched black.

Zikun said: "Brother Yufei, you must be right this time. There is a magma pool above the top of the mountain, and the fire bladder is in it, but... the temperature of this magma is so high that even stones will melt if you fall into it. What should we do?

Where’s the fire bladder?”

Song Yufei didn't know how powerful this magma was, but she really couldn't think of any good solution for a while, so she said, "Go up first and take a look before talking."

Zikun nodded, thinking, this little brother has always been lucky, maybe there is a way.

The two of them walked for about an hour and reached the edge of the top of the mountain. The magma pool was right at their feet. The heat wave continued to hit them upwards. They felt it was difficult to breathe and their mouths were dry.

Song Yufei picked up a stone from the ground and threw it into the magma. The stone fell on the magma and soon began to burn, emitting a wisp of black smoke. Then it turned red, softened, and melted with the magma.

One body.

Zikun shook his head, obviously feeling that it was almost impossible to get the fire bladder.

At this time, Song Yufei asked: "Brother Kun, is the fire gall really in this magma? What does it look like?"

Zikun thought for a while and said: "It is said that the fire bladder is not very big and is round in body, but it is different from this magma. It emits a blood-red light, which is obviously several times brighter than this magma. Otherwise, it would float in it."

No one will notice it even when it is there. As for where it is, I really don’t know. The constant flow of this magma is so different from that of ten thousand years of black ice."

Song Yufei thought to herself, yes, the temperature and pressure under this magma are very high, and there is basically nothing they can't melt. If the fire bladder can resurface, there may be a chance, but it will have to wait for it to surface on its own.

I know what year and month I have to wait.

Song Yufei took out the ice core and thought it would be better to use the ice core to see if it could cool down the magma.

Zikun also understood what he meant and said: "Yes, we have obtained the ice core. We can use this ice core to cool the magma. Maybe we really have a chance."

Song Yufei nodded, holding Bing Xin, and slowly approached the magma. When Bing Xin was close to the magma, the cold air released actually cooled the magma. Affected by the cold air, the magma near the Bing Xin began to slowly darken and turn black, and then

They solidify together, but if the ice core leaves that area, it won't take long for the solidified magma to turn red again, and then start to flow.

It seems that the ice heart can have some effect, but it still can't deal with so much magma. Song Yufei sighed, and went back frustrated. She put the ice heart next to her to cool down, and sat cross-legged on the ground thinking about how to get the fire bladder.

Song Yufei thought for a while, then suddenly stood up and said to Zikun, "Brother Kun, I still want to try."

Zikun also felt that it was a pity to give up like this, and asked: "Brother Yufei, how do you plan to try?"

Song Yufei said: "I would also like to ask Brother Kun for help. Please make some stone balls. The stone balls should be hollow."

Zikun didn't know what Song Yufei was going to do, so he said, "This is easy to handle."

Then he raised his right hand, and the gravel on the ground turned into powder, floating in front of the two of them. Zikun clenched his fist again, and the floating powder immediately turned into a stone ball the size of a watermelon.

Zikun said: "Brother Yufei, do you think it's okay?"

Song Yufei shrugged her shoulders and said: "My fault, this stone ball shouldn't be too big, just this big."

Say this by making a small circle with your index finger and thumb.

Zikun understood immediately and made a lot of them in the blink of an eye.

Song Yufei looked at the stone balls. They were all the same size and very exquisite. She said to Zikun, "Brother Kun, please put these stone balls together so that they are connected."

Zikun followed suit and finished it.

Song Yufei took the stone ball and threw it into the magma. As soon as the stone ball fell into the magma, her mouth began to slowly count the seconds. When the stone ball completely melted and disappeared, Song Yufei counted the seconds.

After more than eighty times, it seems to have a certain effect, but it still cannot meet the requirements.

This was when Song Yufei happened to see the scorched earth next to the lava river and asked: "Brother Kun, you try to use this scorched earth to make earth balls, and they are still the same as the stone balls just now."

Zikun smiled, and the scorched earth balls were ready in the blink of an eye. Song Yufei threw the scorched earth balls into the magma without even thinking about it.

This time, the scorched earth ball actually persisted for half an hour before sinking, and there was no sign of melting.

Song Yufei was overjoyed and thought, it seems this method is effective, the next step is how to use the scorched earth balls to get the fire bladder.
