Chu Feng looked at the demon spirit stone in Su Sha's hand with a curious expression, he couldn't use his divine sense, and he didn't know what kind of energy existed in it.

"What is the effect of cultivating with this demon spirit stone?" Chu Feng asked.

"It's amazing, I just tried it once before, and I feel that the energy consumed in my body is replenished a lot at once. If you can have enough demon spirit stones, your cultivation speed will increase significantly. Su Sha was even thinking that if she could earn a large amount of demon spirit stones and then cultivate by her master's side, then it wouldn't be long before she could recondense the demon pill.

Chu Feng nodded, and then asked, "How did you get this 'Demon Spirit Stone'?"

"We, the Water Shaping Clan, will go to the 'Falling Demon City' to sell herbs every once in a while. Susha said.

"Can you show me what kind of herb it is?"

"That's it. Su Sha hurriedly took out some dried herbs and continued, "We call this herb 'fibrous root grass', which is not precious, and often we need to collect a lot of them before we go to the 'Falling Demon City' to sell them once. ”

Chu Feng's eyes flickered, and sure enough, in response to his previous guess, there were unknown medicinal herbs in this world, and if he could collect some and bring them back for study, he might be able to refine a good elixir.

However, this kind of thing is not in a hurry, it is better to wait until he goes to the "Falling Demon City", and it is not too late to plan after everything is settled, and he believes that there must be more medicinal herbs in the "Falling Demon City".

"Asha, how many demon spirit stones do you have now?" Chu Feng asked again.

Since the demon spirit stone is the currency of this world, and it is also related to the cultivation of the three daughters, it is necessary to get more.

"Master, the demon spirit stones are all here with me, and there are only forty-three pieces. Susha said a little lonely.

Even if it was these forty-three demon spirit stones, they had also accumulated with great difficulty from their "Water Shaping Clan".

Seeing that Su Sha wanted to give all the demon spirit stones to himself, Chu Feng hurriedly waved his hand: "You put away these demon spirit stones, and when you get to the 'Falling Demon City', I want to sell some 'demon talismans', but I don't know what the price is?"

Su Sha couldn't give advice on this issue, after all, the "Demon Talisman" was an untouchable existence for her before, not to mention that the price of the "Demon Talisman" was also very different according to the grade and function.

"Forget it, when you get to the 'Falling Demon City', let's find out the market again. Chu Feng also wanted to see what the "demon talisman" in this world was like.

The topic was a little far away, Chu Feng moved his mind and summoned a few flying swords.

"I don't know if these flying swords are the demon soldiers you mentioned, you give it a try and see if it's easy. Chu Feng motioned for the three girls to choose.

After the previous surprise, the three girls are much calmer now, and without saying anything, they each picked out a favorite flying sword and played with it in their hands.

"Master, can I give it a try?" Su Xue, who hadn't spoken for a long time, asked a little impatiently.

"Of course, since it has been given to you, you can use it as you want. Speaking of this, Chu Feng added, "There will be better ones in the future, even if they are broken, it doesn't matter, I still have a lot here." ”

Su Xue's three daughters were fully aware of the wealth of the master in front of them.

Zheng!

Su Xue waved the flying sword in her hand, only to see a flash of cold light and a clang.

Su Xue had no experience in using "demon soldiers", all she could do was inject the energy in her body into the sword.

Airplanes!

With the injection of Su Xue's energy, the sound emitted by the turquoise sword body turned into a buzz, and the cold light on the blade of the sword rose sharply.

Rao is Su Xue was mentally prepared, but she was still taken aback.

"Ah Xue, how do you feel?" Su Sha on the side couldn't help but ask, she also wanted to try, but the energy in her body was pitiful, and she could only watch it for the time being.

"It's very peculiar, as if this 'demon soldier' is alive. Su Xue hurriedly said, but her eyes never left the sword body.

"I can feel its sharpness, Xue, you try to make a move. Su Sha's appearance was even more anxious than Su Xue's, and she was already urging on the side.

"Okay!" Su Xue nodded, took two steps forward, looked straight ahead, and slashed out with the flying sword in her hand from top to bottom.

"Frozen!"

This is a very simple move, but at this moment, it is no longer so simple to send it out with a flying sword.

Click!

On the ground in front of it, it quickly condensed into ice, and stretched straight forward, and when it reached the location of the wall dozens of meters away, with a snort, the wall made of rocks was easily split in two, and the fracture was covered with ice.

Seeing this scene, Su Xue's whole person was petrified.

She could swear to God, she just tried it casually, after all, it was the first time to use it, where did she dare to take it too seriously.

But the effect was a big surprise to her.

"Ah Xue, tell me, how much strength did you just use?" Su Sha stretched out her hand and pushed Su Xue in the petrification, and asked very concernedly.

"I ...... I was just casual and probably ...... Maybe it's less than a ...... strength" Su Xue hadn't fully recovered from the shock, and she stammered a little when she spoke.

Su Sha didn't ask more, but lowered her head and stared at the flying sword in her hand with fiery eyes.

"I'm going to try it too!" Su Xuan saw that the flying sword was so powerful, and immediately wanted to try it.

Although her strength is not as good as Su Xue, she still has the ability to use demon soldiers.

Rumble!

With a loud bang, a house dozens of meters away was completely turned into ruins, and under the corrosion of an unknown liquid, white smoke was emitted.

"It's amazing, is this really what I did?" Su Xuan looked cute.

Seeing that after the third daughter got the flying sword, there was no longer the previous sadness, Chu Feng was very relieved.

"Master, what is the name of this 'demon soldier'?" Su Xueyu stroked the sword body with her fingers, and it could be seen that she had already liked the sword in her hand.

"You don't have a name, you can pick one yourself. Chu Feng smiled awkwardly.

These flying swords, but they were all picked up by him, even if they had names before, he didn't know.

The three girls each named the flying sword in their hands, and then put it in the storage bag like a baby.

You can't try again now, or the whole tribe will be torn apart again, and the three of them will be sinners.

The matter here has been dealt with, and the next step is to go to the "Falling Demon City".

Susa provided a rudimentary map, which could be reached in less than an hour at the speed of a flying machine and without a detour.

However, there is a rule in the "Falling Demon City" that no one is allowed to fly in the territory of the "Falling Demon City".

For this reason, Chu Feng and his party landed in the canyon that was still some distance away from the "Falling Demon City", and then walked there, although it was a little troublesome, but it avoided being noticed.

"Master, ahead is the 'Falling Demon City'. Susha pointed to the huge city that appeared in front of her, and said in a loud voice.

Finally, it's time to "fall demon city"!
