A new cave opened, and there was a fiery red inside. Red crystals grew on the ground and walls of the cave.

System prompt: "Fire Crystal Stone is discovered."

[Fire Crystal]: Ores that condense flame elements can be refined, or used to create flames.

"It's indeed a fire crystal stone!" Xia Chengfeng guessed correctly. Fire-attribute monsters have fierce combat power, so they should not be encountered by newcomers.

As long as this kind of fire crystal stone hits hard, it will shock the power of the fire element inside and stimulate the flames.

Whether it is used for fire-making and barbecue or forging materials, they are all necessary materials!

Xia Chengfeng carefully collected fire crystal stones and obtained more than 300 units of fire crystal stones. The standard unit of fire crystal stone is only the size of a table tennis ball, but such a unit of fire crystal stones can generate high temperatures of thousands of degrees Celsius and burn for two or three hours!

After collecting, Xia Chengfeng chose to occupy the cave and obtained a primary space crystal again. Then his own space bubble was increased by one cubic meter of space.

He just finished doing this and someone contacted him on the trading channel.

"@Qingfeng, is the owner here? A rusty rune key, change the food!"

"Finally come!" Xia Chengfeng immediately discussed with him.

At this time, several hours have passed since the forum was opened, and some originally confused and ignorant newcomers began to explore the world of caves under the guidance of some experience posts and obtained more abundant resources.

"Five berries, transaction." Xia Chengfeng spent five berries this time, and the prices of the trading channel have been changing.

He estimated that in a few days, berries would depreciate several times, and meat, or other high-end ingredients would be valuable.

"Get the rusty rune key." An ancient rune key with rusty appeared in Xia Chengfeng's hand.

He took out the rusty rune chest and brought the rune key close to it.

A ray of light flashed, and the rune mark on the rune key and the rune mark on the rune treasure chest disappeared together, and the treasure chest could be opened.

"Blessed by God Ou!" Xia Chengfeng opened the treasure chest, and two sheepskin scrolls were quietly lying inside, with a faint magic fluorescence flashing on it.

[Sharp Knight's Sword Design Drawing]: Primary design drawing, you can obtain the [Sharp Knight's Sword] production skills after learning.

Materials required: fine iron 5, fire crystal stone 5.

[Basic Sword Art]: A primary skill book, you can obtain basic sword skills after learning.

"There are actually two scrolls, and you're not lucky." Xia Chengfeng was very satisfied. Generally, it is difficult to open good things in the early treasure chest.

Moreover, the design drawings are actually more precious than long swords. If you get the long sword, you can only use it yourself. After you consume the durability, the long sword will be damaged.

But after getting the design drawings, you can continue to manufacture and sell them for money.

At this time, everyone lacks weapons. If they can sell weapons, someone will definitely rush to ask for them!

Xia Chengfeng immediately chose to learn design drawings and skills books, and a stream of information poured into his brain.

The entire process of making a long sword appeared in his mind, and some fragments of sword practice appeared.

After opening the treasure chest, the materials of this treasure chest cannot be wasted. Xia Chengfeng directly decomposed the broken rune treasure chest.

System prompt: "Get Metal Fragments +5, get Banned Rune Fragments +5."

[Block Rune Fragment]: Can be used to fuse into ban runes, currently 5/10.

Xia Chengfeng immediately went to the trading channel again to buy fine iron ore.

This thing is not rare, and he easily exchanged it for a few berries.

"Successfully decompose refined iron ore and get refined iron +9."

He took out the fire crystal stone again and hit it hard. The energy of the fire element in the fire crystal stone trembled and a raging flame burned out.

"Start quenching." The physical laws of this world are different from the original world. After the energy of the fire element impacts the essence iron, the essence iron is quickly melted into iron.

Then, he poured it into a mold made of soil and condensed it into molding.

After learning to design drawings, he can guide the power of the fuse element, so that the condensed sword embryo can be used directly without pounding, quenching, etc.

Advanced weapons also need to be tempered, but this low-level weapon can directly omit this process.

Xia Chengfeng created two in total.

System prompt: "Get [Sharp Knight's Sword] +2."

[Sharp Knight's Sword] (Inferior): A rough-made sword can be used to attack.

[Sharp Knight's Sword] (Ordinary): An ordinary Knight's Sword will exert unexpected power in the hands of a real knight.

Xia Chengfeng chose to use the one with better quality, and then he placed the inferior ones on the trading platform for sale.

Qingfeng: "Hang a long sword, defend yourself, attack weapon, slow hand, no items required: (high-end ingredients, high-end ore, treasure chest, treasure chest key, various scrolls, etc., those who are interested can come quickly!)"

At this time, most of the trading channels in the 2222 area were still trading food and water.

When Xia Chengfeng's weapon was hung out, a large number of replies immediately appeared.

"Selling weapons? The boss got the weapons so quickly? I'm still using stones. I just met a gopher bigger than a dog, and almost bit me to death!"

"I really want it. My demon soul is the soul of a knight. If there is a knight's sword, I guess it can beat ordinary monsters in the cave!"

"@Qingfeng, I have a bag of wheat here. Can I change it?"

"Big Boss, have you released something good again so soon? Do you need a little brother? Please cover it, please support it! (Self-photo)"

Xia Chengfeng looked at the messages they sent, and most of the things were items of very low value and he didn't need them.

There was a message that caught his attention, and it was sent by Wu Rui, the former boss of his company.

Wu Rui: "@Qingfeng, this friend, I have some things here. Do you want it?"

"【Exquisite iron pickaxe】,【Songcao seeds】,【Furniture manufacturing drawings】,【First-order energy crystallization】..."

"He has so many things?" Xia Chengfeng felt a sense of crisis. You should know that the attributes that demon souls can swallow each other and grow up represent that players will encounter and fight in the future.

The stronger others are, the greater the threat to themselves!

Wu Rui probably has joined forces with hundreds of employees of Tianxun Company before. With the support of these hundreds of people, he has so many resources.

Among them, first-order energy crystals are what he wants most.

This kind of thing can allow humans to use, strengthen themselves, and gain energy. In the words of previous online novels, it is so-called spiritual power, fighting spirit and other things.

"Since that's the case, I have to make more points!" Xia Chengfeng looked at it and sent a message:

"[Sharp Knight's Sword] for [Exquisite Iron Pickaxe], [Shining Grass Seed], [Furniture Manufacturing Drawings], [First-order Energy Crystal] and ten [Carrot Seeds]."

Wu Rui: "Friend, you are too greedy. Your long sword can only be replaced with one or two of them!"

Xia Chengfeng disagreed and said, "You are not considered essentials for survival, and my long sword is much more precious than this!"

"If I encounter a monster in the cave, without a long sword to save my life, it would be useless no matter how many other things you have! And now I am the only one selling weapons on the trading channel, and others are willing to bid!"

Xia Chengfeng is definitely not the only one in the 2222 area, but most of the weapons can only be used by themselves and will not be traded.

Even if they have weapon drawings, they do not have the corresponding materials. After all, if they want to obtain forging materials, decomposition talent is essential!
