However, in the dark secret world, humans will automatically become professionals after undergoing the awakening ceremony and stimulating the Nephalem bloodline power in their bodies, depending on each person's situation. At the same time, they will automatically master one or two of the most basic professional skills, but they cannot obtain a complete skill tree. From then on, all skills need to be acquired by the professionals themselves, either by learning from seniors of the same profession, or by obtaining them from wild treasure chests like Xu Feng. Of course, they can also comprehend them on their own, but only a genius that is rarely seen in a century can comprehend professional skills on their own.

It is precisely for this reason that the skill stone in Xu Feng's hand is extremely precious. Summoning fire snakes is a high-level skill for mages. In the entire Rogue Camp, there are very few mages who can master this skill. Once Xu Feng takes out this skill stone to sell, the price will start at at least 30,000 gold coins, and the final transaction price is likely to exceed 100,000 gold coins.

This information was naturally told to Xu Feng by Kane. When Xu Feng knew that the skill stone in his hand was likely to be worth more than 100,000 gold coins, a surprised smile suddenly appeared on his face. Although gold coins were of little use to an outsider like him, he could use them to buy items and equipment that could decompose the source energy of heaven and earth and the power of laws.

"If I use all of the 100,000 gold coins to collect items containing the source energy of heaven and earth, I should be able to use all of my 36 Dinghai Divine Pearls to open up the chaotic space, right?" Xu Feng guessed in his heart.

Xu Feng solemnly put the skill stone into the package column and looked at the remaining two items;

One oracle rune can be directly embedded in equipment to gain powerful extra strength. Another use is to obtain two or three more oracle runes. Putting them together in the Horadric Cube can synthesize a more powerful oracle rune. If sold, the value of this rune is about three thousand to five thousand gold coins. However, for Xu Feng, the greatest function of this oracle rune is to decompose it and obtain the source of heaven and earth. Moreover, according to the detection of the Eye of Identification, the source of heaven and earth obtained after the decomposition of this oracle rune is at least ten times heavier than the previous "broken skull". "I have obtained two broken skulls now. As long as I get one more, I can synthesize a complete skull. The source of heaven and earth contained in the complete skull should be similar to that in this rune, right?" Xu Feng guessed, but he was not in a hurry to decompose the oracle rune immediately. After all, it was not safe here. Xu Feng planned to complete the task and follow Kane back to the Rogue Camp before opening the chaotic space in the Dinghai Shenzhu.

The last item is a parchment scroll that emits a faint dark gold glow. This is a dark gold item. In the dark world, besides the green suit, the dark gold items are the most valuable. Sometimes, even the individual pieces of the green suit may not be able to compare with the dark gold items before they are completed and have the suit attributes.

"This cursed treasure chest really did not disappoint me. I am very satisfied with the items inside. Now let me see what this last high-value item is?" Xu Feng smiled as he unfolded the last item and carefully checked its properties.

A big fortune, Xu Feng definitely got a big fortune this time. The items he got now have made him satisfied. This dark gold sheepskin scroll can be said to have completely exceeded his expectations.

"Is this... a title deed?" Xu Feng couldn't believe his eyes. This sheepskin scroll turned out to be a title deed.

Xu Feng turned his head and looked at Kane. From Kane's confused look, Xu Feng could tell that this deed was definitely not an item from the secret realm of the dark world. Who is Kane? He is definitely a living encyclopedia in the entire dark world. As long as it is an item in the dark world, there is absolutely nothing he doesn't know. Otherwise, how could he identify everything and become the last sage of mankind? "Kane, haven't you seen this either?" Xu Feng couldn't help asking.

Kane stared at the parchment scroll in Xu Feng's hand for a long time, and finally shook his head regretfully and said: "This world is full of unknown things, and I can't be omniscient and omnipotent, but this item does not have the aura of this world, so it should not belong to this world!"

"Just as I guessed!" Xu Feng said in his heart and took the parchment scroll back.

Xu Feng stared at the parchment scroll in his hand and thought to himself, "This kind of title deed is the second most valuable treasure in the secret world after the secret core. If you own the secret core, you can obtain the land of the entire secret world. If you own the title deed, you can split off a part of the secret world. The title deed is what the secret apostles call the small core of the secret world!"

"It's a pity that although I have obtained many secret realm cores in my previous life, I have never seen this kind of easier-to-obtain title deed. I didn't expect that in this life, I would get this treasure with my own hands in the secret realm of the upper realm!" Xu Feng's face was filled with a bright smile.

This treasure is indeed not a specialty of the secret world. Strictly speaking, it is a treasure specially prepared for the secret apostles. Only the secret apostles can obtain it from the secret world. The natives of the secret world cannot obtain it. Just like the core of the secret world, many natives of the secret world cannot get it even if they know of its existence.

"With this deed, I can legitimately become the lord of the Blood Wasteland..." Xu Feng thought to himself, "I can even use this contract as a beacon to enter this secret world at any time, develop the Blood Wasteland, and make it my own territory!"

"It's just that the power of the demons in this world is too strong. It's obviously not a good idea to find it here!" Xu Feng thought to himself: "It's better to completely isolate it from this secret world!"

"It's just that the Blood Wasteland is filled with evil power, and every inch of the soil is eroded by the power of the devil. If we rashly integrate it into the secret realm, it will be a huge project just to purify this land!"

When Xu Feng thought about purifying the land that was completely infected by blood and demonic power, he couldn't help but frown and felt a headache.

“It is better to integrate it into the chaotic space within the Dinghai Divine Pearl and let it slowly grow into a small world similar to the dark world…” Xu Feng said with a sigh.

If he could integrate the Blood Wasteland into his own secret realm, his secret realm would surely be upgraded from a blessed land to a small world. However, with his current strength, he could not fully control a small world, just like a small horse pulling a big cart. By then, his combat effectiveness would probably decline instead of improve. Most importantly, the evil power in the Blood Wasteland was too strong, which would pollute Xu Feng's current secret realm. By then, if he failed to complete the upgrade, his secret realm would be turned into a dark-style wasteland. The decline in rank would not be worth the loss, and the cost of purifying this land was too high. Xu Feng could not do that. It would be better to wait until the chaotic space in the Dinghai Divine Pearl was opened up, and then integrate the Blood Wasteland with it, and use it as a guide. In the future, there might be a possibility of becoming another dark world...
