Seeing the two of them falling from the sky, the two little Taoist children respectfully stepped forward and knelt at their feet: "Two immortals, the ancestral god has sent down an oracle, and I have specially ordered the two of us to wait here." Two immortals, please come with us. ”

The little Taoist children had already prepared everything according to the oracle of the "ancestral god". And Sun Ang secretly observed that the speed of time here was different from that of the outer main world, and it was much faster.

He and Xing Yixian were taken into a courtyard, two opposite houses, the doors were open, and there were jade tripods, Dan furnaces, and various materials neatly arranged.

"This is it, the two immortals, please take their places, I'll step back. The children bowed and exited, closing the courtyard door. Xing Yixian didn't look at Sun Ang, he snorted coldly with his hands behind his back and turned into his house.

Of course, Sun Ang didn't have any kind looks at him, and roughly looked at the entire courtyard, and then entered his own house as well.

The Dust Void Ancient Tree was of a very high level, and even for the Creator, it was a very rare eighth-order material. These trees are extremely long-lived, usually able to grow for thousands of years, but they must be more than 10,000 years old to be called "ancient trees".

When they reach the dusty trees that are more than 10,000 years old, some small changes will occur, and under their thick and hard bark, there will be a new layer of soft skin every extra year.

This new tree material is excellent, like rice paper, which can transmit the energy of the element very well, and is the best of the wood element materials.

However, the fire seal is a kind of fire element sigil, which is inherently restrained from wood element materials.

In order to successfully carve the painting, it is necessary to concoct the bark of the dusty ancient tree, and this kind of concoction requires the use of the means of making Dan, so this is a difficult problem for Dan craftsmen.

It is very difficult to master the skills of the three basic classes perfectly and cooperate with each other.

Xing Yixian has basically given up, although he thinks very highly of himself. But I don't think I can surpass those dozens of predecessors. So he looked at all kinds of materials in the house, tried them a few times, waited for the time to come, and then went out to "tie" with Sun Ang.

This made him very unhappy - I should have won, and that kid was lucky to have drawn such a puzzle.

......

Sun Ang's hands flew, all kinds of mysterious and esoteric treatment methods kept being unleashed, and in the small jade tripod in front of him, the bark of a dusty ancient tree was tumbling in the medicinal juice.

The juice was thick, and from time to time flames tumbled out in it. These flames only rolled around the bark of the Dust Void Ancient Tree, and did not really burn.

For the current Dan Craftsmen, this is indeed a century-old problem, but for the ancient Dan Craftsmen, this is just a slightly "difficult" test.

The current level of Dan Craftsmen is indeed far from the true heyday of this profession in history, and there is indeed a certain gap. However, the gap is not as big as imagined.

The biggest difference between the present and the ancient is that everyone explores in different directions.

Today's Dan Ware Masters are almost completely different from the ancient Dan Ware Masters in the direction of Dan Ware refining. Therefore, although everyone is somewhat similar in technique, the concept is very different.

But there is often more than one path to the end. Therefore, everyone is not a failure, but a complete success.

This problem is also due to the fact that the concepts of the ancient Dan masters are different from those now, and there are some changes in the handling techniques. It's a lot easier.

Sun Ang's hand shook, and a trace of purple flame tumbled out of the medicinal juice, and with a whoosh, it wrapped around the bark of the Dust Void Ancient Tree, burning the palm-sized bark to ashes almost instantly.

Sun Ang smiled bitterly. I had to start all over again. It is indeed not easy to refine the Dan Weapon.

No matter what kind of respectable profession it is, behind the prominence and reverence in front of people. All of them are accompanied by extremely high failure rates and long lonely withering.

Sun Ang tried more than a dozen times in a row before he could dispose of the bark of the Dusty Ancient Tree, and then began to carve the seal of Lihuo Yan on it. Although the bark has been treated and has a high tolerance for fire elements, it is still a wood element material after all. Therefore, we should also be careful in the process of seal carving, and do a good job of protection while carving.

Sun Ang has been cautious and cautious, but his lack of experience still caused him to fail four times in a row.

After these four times, Sun Ang felt that his energy was about to be exhausted, so he exhaled, threw all the materials aside first, and then fell asleep on the soft couch on the side.

Having recuperated his spirits, he started again.

"Whew-"

A flame of flame emerged from the bark of the Dusty Ancient Tree, following the lines of the sigils that had been carved into the seal, quickly burning the entire bark to ashes.

Sun Ang scratched his head in embarrassment: "I'm too full to eat, and I'm not concentrating." ”

The next two times, still unsuccessful. Finally, when it was time to get up four times, he tried his best to save a mistake, and then completed the seal carving this time with trepidation.

When the last rune was completed, Sun Ang breathed a long sigh of relief, and suddenly felt a little unbelievable: it was actually completed?!

"It's really done. He confirmed it himself, and the bark of the Dust Void Ancient Tree, which had been engraved with the seal of the Flame of Flame, fully met the requirements. He took it in his hand and smiled bitterly: "It's really much more difficult than I imagined, and sure enough, the water in Tianjie is deep, and any question is this difficulty." ”

He put the bark in a box and walked out with it in his sleeve.

The time limit for this problem to be completed was ten days, and Sun Ang failed one after another, plus the time to rest in between, and when he walked out of the house, the time consumed was almost ten days.

didn't wait long, and the door on Xing Yixian's side also opened, exactly ten days.

"Congratulations to the two immortals. The two little dao boys bowed down, and a divine golden light was projected in the sky, enveloping the two of them, and flying out of the sky at high speed with a whoosh.

......

Outside Zhu Yan City, in the Taoist temple on the mountain, everyone has been waiting for a day, and according to the time Tai Shenghua said, they will appear in the courtyard on time the next day.

As soon as Zhao Minglie and Cao Jiawu saw Tai Shenghua, they hurriedly came up and asked, "Sir, who do you think can win?"

Tai Shenghua's expression was a little strange, and he hesitated for a moment but said: "This game is definitely a draw, and the second game has to be played." Then he continued: "According to the concept of justice in the streets, the second game must be played in the third game, and the final decision must be made in the best of three games. ”

"Huh?" the two supreme powerhouses were surprised: "Sir is so sure, why is this?"

Tai Shenghua smiled bitterly: "You may not know this question, but it is really one of the three major century-old problems in my Tianjie......

As soon as he explained, the two of them were relieved, and they also shook their heads and smiled bitterly: "It seems that the mystery will be revealed two days later." The two of them, it's really ......" The two didn't know what to say, there were thousands of questions in that thousand treasure box, and they chose this one.

"They're back. Tai Shenghua spoke, and with a wave of his sleeves, a golden light flew out. The two of them were enveloped in a ball of holy light, and they flew out of the upper forest realm with a whoosh.

After landing on the ground and standing firmly, the two first saluted Taishenghua. From the greetings of the supreme powerhouses around him, Sun Ang had already deduced that the ratio of time flow speed between the main world and the upper forest realm was one to ten, and ten days over there, only one day had passed in the main world.

Tai Shenghua looked at the two of them and asked routinely: "Have you two solved this problem?"

His hand had already been retracted into his sleeve, and when the two of them shook their heads together, he would announce the second game, and directly release a thousand treasure crates for them to continue to choose the topic.

Sure enough, Xing Yixian took a step forward, bowed down and hugged his fists and said, "The disciple has never solved this hundred-year-old problem. ”

Tai Shenghua nodded, and looked up at Sun Ang again.

Sun Ang was a little surprised: "A hundred-year problem?"

Tai Sheng Hua said: "Yes, this is one of the three hundred-year problems of my Heavenly Street low-level Dan Artifact Master, so even if you try your best, you can't do it, don't be discouraged, it's not that your strength is insufficient......"

Xing Yixian was extremely jealous on the side, and His Excellency Tai Shenghua was constantly encouraging Sun Ang, this is the benefit of someone behind it, alas.

But Sun Ang slowly took out the box in his sleeve with a strange face, presented it with both hands, and said with some uncertainty: "Senior, I did it, but since it is a century-old problem, it must not be so simple, please see if I did it wrong?"

"Did you make it?" Tai Shenghua was stunned for a moment, and then he was relieved when he heard what Sun Ang said, and stretched out his hand and said: "It's okay, although it is likely to be wrong, but it is also good to have the courage to try." ”

So Sun Ang handed it over, and Xing Yixian on the side sneered, and lightly spit out four words: "Don't measure yourself!"

Tai Shenghua glanced at him, a little cold. Xing Yixian shrank to the side, not daring to say anything more.

Tai Shenghua opened Sun Ang's wooden box, twisted the bark with two fingers, and gently rubbed it, and a stream of yuan breath was injected into it. On the bark of the tree, the seal of the flame shone brightly.

"Huh?" Even Tai Shenghua shuddered and almost fell down.

The fourth-order Separation from Fire Flame Seal, engraved on the bark of the Dust Void Ancient Tree, with the support of powerful wood energy vitality, the power of the Separation Fire Flame Seal has been increased several times!

To put it simply, this truth is to add firewood to the super fire.

A trace of dark golden flames flew out, which caught Tai Shenghua a little off guard, and almost burned his hair.

"It turned out to be a success!" Tai Shenghua was taken aback, and activated a light shield in his hand in time, enveloping the entire Dust Void Ancient Tree bark in it, and only then did he control the power of the Flame Flame Seal. (To be continued......)
