The five large barrels of cold Jiao blood, or the cold Jiao blood that was about to enter the Great Grandmaster, only refined five tears of dragon blood the size of tears in the end.

In this regard, Du Yun was speechless.

This is still the early stage of the first layer of the Dragon Transformation Technique, and if you cultivate further, you don't know how much dragon blood you need to absorb before you can continue to break through.

Well...... Finding monsters with dragon blood is also a big problem!

However, after absorbing half of the content of the first layer of the "Dragon Claw" of the five drops of dragon blood basic cultivation into the Dragon Technique, Du Yun suddenly became extremely satisfied when he looked at his right hand that had transformed into a dragon claw.

He could clearly feel that the five drops of golden dragon blood from before had fused with the blood on his right hand, staining his own red blood with golden light.

Waving the dragon's claws, the terrifying power erupted, and the air resounded with a "poof" boom.

"This level of power...... Even a martial artist with the strength of the late stage of the grandmaster, if he is close to me, I am afraid that he will not be able to withstand the blow of my dragon claw! ”

Du Yun smiled and muttered to himself.

Immediately, under the influence of his consciousness, the golden dragon blood that gathered in the veins of his right hand was hidden again, and the dragon claws turned back into normal hands as the dragon scales faded.

If you want to use it in the future, you can change it into a dragon claw at any time.

At this point, Du Yun can be regarded as truly understanding the true role of the dragon transformation technique, which is actually to continuously refine the dragon blood and absorb it, and replace the human blood in his body with the dragon bloodline.

Once he reaches the highest level of the dragon transformation technique, the dragon, he will probably become a real dragon.

But it's just getting started, and it's useless to think about it so much.

The most important thing for Du Yun now is to improve his strength, complete the goal stated by the mysterious voice at the beginning of the apocalypse, and then figure out the real reason for the change in the sky.

It's all about living better!

When I looked up at the sky, it was already completely dark.

Du Yun smelled the smell of sweat emanating from his body, and did not continue to cultivate here, but put away the empty five large barrels, and walked out of the backyard with his feet raised.

……

In the following two days, Du Yun was rarely relaxed, and most of the time he was accompanied by Wen Ji and Zhu Rong to and from Nanshan City, Beishan City, Zheng Wencheng, Xilin City and River Valley City.

Because they are all equipped with teleportation arrays, it is extremely convenient to travel back and forth.

Occasionally, they would take the Beishan warship in Beishan Castle and float down the river to enjoy the beautiful scenery on both sides.

You must know that the last time I was in a hurry, I didn't have the opportunity to think about what was beautiful or not.

During this period, after tasting the cold Jiao meat that Lu Bu and the others brought back, Guo Jia and the others who stayed behind said that it was a pity that they didn't go with them at the beginning, otherwise it wouldn't have been saved so little meat and it would have been gone before they ate it!

Therefore, after these people at the congenital level have dealt with official business, they directly seize the time to retreat and cultivate.

After Guo Jia studied the basic formation method, he laid out the small Juyuan array that he had just learned, and the rich vitality transformed into the inlaid yuan stone was easier to absorb, and the strength of everyone was rapidly improving.

And Guan Yu's several legion commanders who led the six legions took this opportunity to gather the warriors of the land of the five cities, and absorbed a large number of martial artists whose strength was above the quadruple level of the day after tomorrow into the legion.

At the same time, the Tianhe Sword Sect and the Martial Pavilion, which was in charge of the monks of Nanshan Temple, also sent a large number of warriors to join the legion.

As for the three white tigers who had just broken through to the innate realm when they grew up, except for one that was occupied by Zhu Rong, the remaining two were grabbed by Guan Yu and Zhao Yun.

However, compared to the others, their fighting style is indeed more suitable for riding combat!

For this reason, the remaining Dian Wei and Zhang Fei directly found Du Yun and pestered him to mount.

You must know that these two people belong to the type of five big and three thick, and their skin is thicker than rhinoceros skin, and they will not let go when they are entangled, which annoys Du Yun with a straight headache.

In the end, Du Yun had to promise them a chance, and after finding them a mount first, the two of them left with a happy face.

On the morning of the third day.

As usual, Du Yun was going to go to River Valley City to have a look, and by the way, he asked Shi A about his inspection of Dongshan Province.

But he had just walked to the gate of the City Lord's Mansion, and as the vitality in the air around him increased greatly, he saw that there were clouds and mist in the backyard of the City Lord's Mansion churning violently, and there was faint rain falling from the clouds.

The ground shook slightly, too.

"Childe, this is ......"

Finding such a situation, Wen Ji and Zhu Rong, who were accompanying them, showed surprise on their faces.

"The low-grade Yuanshi vein in the backyard has been upgraded to a medium-grade Yuanshi vein!"

After coming back to his senses, Du Yun explained, and then apologized to the two: "I'm afraid I can't accompany you to Riverdale City this time!" ”

Wen Ji shook his head and said, "It's important for the son to do the right thing, you can go to River Valley City at any time." However, after the Yuanshi vein is upgraded, is Childe going to raise the level of Nanshan City? ”

"Hmm."

Du Yun nodded.

Then he called a soldier on duty at the City Lord's Mansion and asked the other party to inform Guo Jia and the others to come to the City Lord's Mansion, then he turned around and walked straight to the backyard where the clouds and mist were churning.

Wen Ji and Zhu Rong were curious, and they also followed.

……

In the backyard of the City Lord's Mansion, after Du Yun came here, he immediately felt that the vitality in the air had increased more than ten times compared to before, and he suddenly felt refreshed when he took a breath of air.

Because the vitality is too strong, it rains a thin amount of vitality in the sky

He first checked the yuan stone vein, and sure enough, it had become a medium-grade yuan stone vein, and the yuan stone content was no more than 110,000 pieces, and it could be recovered.

Finally, after glancing at his personal information, Du Yun suddenly exclaimed: "It is worthy of a medium-grade yuan stone vein, and even the cultivation speed has increased a lot!" ”

He found that cultivating in such a vigorous environment could actually get four or five hundred experience points per hour.

Not only Du Yun, but Wen Ji and Zhu Rong also showed surprise on their pretty faces, and they couldn't help but roll up their long sleeves to reveal their delicate arms, and accept the washing of the vitality and rain in the air.

Soon, Guo Jia, Tian Feng and others who were notified all arrived here.

The rich vitality of the backyard also shocked them.

But then, these people's attention shifted to Du Yun.

Guo Jia even opened his mouth and asked: "Lord, I don't know what is important, but I actually summoned all my subordinates and others here?" ”

Because of the existence of the teleportation array and the transmission jade jian, whether it was in Nanshan City or the deputy general in the city, after getting the news, they all put down their work and rushed back.

More than 20 people stood in the backyard, their faces full of doubt.

Hearing Guo Jia's inquiry, Du Yun, who had not informed the other party of this matter, suddenly chuckled and said, "The lower grade yuan stone vein has successfully transformed into a middle grade yuan stone vein, and today this city lord is ready to promote Nanshan City to the first level!" ”

Promoted to Nanshan City?

Guo Jia, Tian Feng and others were stunned for a moment, and then their faces were full of expectation.

At this time, Du Yun didn't pay attention to them anymore, turned around and walked directly to the town monument, stretched out his right hand against it, and said lightly.

"Promote Nanshan Castle to Midtown!"
