"Honestly, take care of everything you need for the voyage, and don't say I didn't warn you if you die halfway. ”

Du Feng slapped Feng Leizi on the head and asked him to purchase things honestly. Sailing on the sea, anything can happen. For example, in some areas, warriors will become like ordinary people. Not only was he unable to mobilize the true element, but he was also unable to swallow the pill to replenish his energy.

Therefore, warriors who go to sea need to prepare something to eat. Don't put it in a bag or storage ring, but get a bag to carry on your body. Because when you arrive at the Forbidden Spirit Zone, you can't even open the storage props.

"Okay!"

After being reprimanded by Du Feng, Feng Leizi lowered his head and went to purchase honestly. And Biyun, that kid, sneaked into the city by himself and didn't know what secret activities he was doing.

Du Feng was not in a hurry to purchase, he usually prepared everything very well. All kinds of preserved fruits, dried meat and even live sika deer, hares, etc., are also raised in the necklace small world. There are several sets of kitchen utensils for cooking, just to cope with unexpected needs.

He found a relatively large looking inn and rented a suite for money. Inside, there is a living room and three separate bedrooms, with plenty of space for three people to rest. I don't know why, Du Feng paid for a year's house at once. Although the price here can't be compared to Lan Ting Pavilion, it is not cheap to rent a suite for a year.

After completing all the formalities, he went into the room and checked it out. I felt that there was really no problem, so I took out the big stone that I stole with Situ Yaoyao.

"Good thing, Brother Du, you peeled off the outer layer of skin. ”

As soon as the big stone was placed on the table, Xiao Hei appeared. As a divine beast, its vision will naturally not be low.

"You know this thing?"

Although it took a lot of effort to steal it out, Du Feng didn't know what it was, but he heard Situ Yaoyao say that this thing was similar to the function of Ruoshui Jade.

"Yes, this thing is called Kunshan jade, and it exists in the mountain. ”

"By the way, you'll need to cool down your room from the light first. ”

He is worthy of being a descendant of a divine beast, and there are many precious memories from his ancestors in his bloodline. Xiao Hei not only recognized that it was Kunshan jade, but even knew its function and preservation methods. Thanks to its size, otherwise if Du Feng hastily cut it, I'm afraid he would waste a large part of it.

It turns out that this thing is called Kunshan jade, and it is afraid of light and heat. According to the method that Xiao Hei said, Du Feng closed all the doors and windows, and deliberately arranged several formations. It can not only play the role of defense and warning, but also cool the room.

The absence of external light did not prevent Du Feng's next move, because two cold lights shot out of Xiao Hei's eyes, which were very bright but without any temperature would not affect Kunshan Jade.

Tut-tut...... It's good to raise a divine beast as a spiritual pet, not only has high growth potential, but also understands so much knowledge. Comparatively speaking, although the pterosaur was of a high level when it was caught, it did not have the potential to grow in the later stage. The only benefit is the ability to fly with wings. In the no-fly zone of some warriors, it can still play some role.

"Squeak ......"

It was really not easy to get rid of the rusty skin on the outside of Kunshan jade, Du Feng tried many methods, and even the Silver Dragon Sword, which he had promoted many times, couldn't do it. In the end, it is still possible to carve with a gold needle. However, the Gengjin needle is too thin, and it can only scrape off a trace of silk skin at a time, and if you want to unravel the entire Kunshan jade, you have to work a lot hard.

I have to say that Du Feng is very patient, and his finger power is really enough. Just pinched a small Gengjin needle, never scratched on the Kunshan jade, and scraped off the hard skin.

"Good thing, good thing indeed. ”

After removing the skin, the Kunshan jade is crystal clear and has a little chill. In terms of nature, there are indeed similarities with Ruoshui jade. But there was another problem that made Du Feng difficult, that is, how to peel off a thin layer from such a large piece of Kunshan jade. This layer must be neat and large enough to roll into a barrel.

If you use the silver dragon sword, you can't sharpen it, but if you use the gold needle, you can't smooth it anyway.

"Brother Du, don't you still have a good thing. ”

Just when Du Feng was worried, Xiao Hei spoke again. Without Xiao Hei's help, Du Feng could only go to the Array Mage Alliance to check the relevant data. But with this baby, it's different, it has too many useful things in its little brain.

One yuan of heavy water can be used to cut Kunshan jade, if it weren't for Xiao Hei's reminder, Du Feng really didn't know. Such a magical method, I'm afraid even the Four Emperors may not be able to know. The ancient memory of the divine beast is really powerful.

Of course, one yuan heavy water does not mean that a drop of Kunshan jade will automatically stratify. He needs to condense the water into a water knife before he can cut the Kunshan jade. This cohesion must be strong enough for the waterjet to be stable enough to achieve the cutting effect.

The thinner the waterjet, the thinner and smoother the Kunshan jade slices that can be cut. Du Feng sat cross-legged on the spot, and after adjusting his state for a while, he took out his bottle of precious one-yuan heavy water. Last time, in order to quench the silver dragon sword with this thing, I poured half a bottle into the small lake, and now there is only half a bottle left.

Half a bottle poured into the lake in the small world of the necklace, although it will not be stolen by others, it can no longer be purified. At least with Du Feng's current cultivation, he can't do anything so difficult. However, the remaining half bottle is more than enough to condense a water jet. After all, the thinner the waterjet, the easier it is to use, and the volume does not need to be too large.

For the sake of safety, Du Feng used his true yuan to continuously compress the one-yuan heavy water, until it turned into a knife as thin as a cicada's wings.

"Whoa......

The cutting process is unusually smooth, as if a sharp knife has cut through tofu. It is completely two different feelings from peeling Kunshan jade with a gold needle before. It's really a thing in the world, and the waterjet cutting jade is so easy to use.

Looking at the thin layer of Kunshan jade in his hand, Du Feng had a smile on his face. This jade is really not simple, don't look at only a thin layer, but it is still very strong. Even if you hit it with a hammer, you can't smash it. Of course, it is impossible to roll such a hard thing into a cylinder. The only way is to pick out the round tube from the large piece of jade.

As long as it is thin enough, then this piece of jade can be cut out of many cylinders of different thicknesses. The big cylinder covers the small cylinder, and each cylinder can be used as the barrel of the real yuan cannon.

"Bang ......"

Du Feng was thinking about something beautiful when he suddenly heard someone slamming the door outside. I've been wrapping it up for a year, what kind of person is so short-sighted, and he actually came to make trouble at this time.
