During this continuous refining process, three days passed in the blink of an eye.
Lin Feng's fighting spirit level at this moment has also increased to the peak of three-star fighting sect.
"Damn it, I didn't expect the hurdle from beginner Dou Zong to intermediate Dou Zong would be so difficult to overcome."
Sensing the few remaining spots of demonic poison in his body and the invisible barrier that he had been unable to break through, Lin Feng began to become more and more anxious.
Now he could finally understand why so many people were stuck in a certain realm and unable to advance for decades.
As the calcination continued, the black spot in front of Lin Feng had completely disappeared.
The skin color in that area also returned to normal.
"Whether we can advance depends on this time!"
Lin Feng gritted his teeth, gathered the last bit of fighting spirit he obtained from the evil poison spot, and rushed towards the invisible barrier.
"Break it for me!"
As the shout fell, the fighting spirit and the barrier collided with each other with a loud bang.
"Bang!"
After holding on for a few breaths, a dull sound suddenly echoed in Lin Feng's body.
A stronger aura than before quietly spread around.
"Hmm?"
This aura instantly attracted the attention of the little medical fairy not far away.
Sensing that aura, she opened her lips slightly and murmured, "Is this a breakthrough to the four-star Dou Zong? I didn't expect that Xie Bi Yan would give him such a big gift. I wonder if the old guy will be so angry when he finds out."
Immediately, he thought of the soul and body of Scorpion Bi Yan, which had been refined into puppets by Lin Feng.
He shook his head again and chuckled, "I'm afraid that old guy won't know."
While the former was talking to himself, Lin Feng slowly opened his eyes.
"Huh~"
He exhaled a puff of light black mist, and then he couldn't help but grin with joy.
He successfully advanced to the four-star Dou Zong this time, and he will be more confident when exploring the Dou Zun ruins afterwards.
But after thinking for a moment, he decided to go to the auction house here later.
There are a large number of these mercenaries in the city, who make a living by hunting monsters.
The quality and quantity of magic cores and medicinal materials are generally greater than those in other cities.
In this Digang City where a Dou Zun powerful warrior is stationed, we should be able to find some excellent quality seventh-level magic cores.
Whether he is refining the Heavenly Demon Puppet or casting the Taixuan Fire Control Formation, he needs to consume magic cores.
Therefore, it is natural to prepare more.
Of course, he also had to buy some medicinal materials needed to refine the seventh-grade high-level elixir.
When he was in the Tianshan Blood Pool, his soul power had reached the advanced seventh level.
But so far, all his attempts to refine pills of that level have ended in failure.
Now that I'm in a place like this, I naturally have to buy some medicinal herbs to practice.
"Sir, this is what you need, check to see if there are any errors."
In the VIP room of the largest auction house in Digang City, an old man carefully came to the sofa and handed over the jade plate in his hand.
Inside the jade plate, a storage ring was placed neatly.
Hearing this, Lin Feng took the storage ring from the jade plate and began to examine it.
After confirming that the three seventh-level magic cores, two masks that could conceal their identities, and many medicinal herbs were all correct, he nodded with satisfaction.
While accepting the ring, he said, "The quality of the item is good, no problem."
Seeing that the big customer was satisfied, the old man rubbed his hands and said with a flattering smile: "Customer, then what do you think?"
"for you."
Seeing this, the little medical fairy at the side took out a few jade bottles from the Yin Po Ring and threw them over.
After taking the jade bottle, the old man quickly poured out the pills inside to check.
After making sure there was no problem, he put it away with a smile.
When Lin Feng saw that the transaction was completed, he walked out of the auction house.
The person in charge of the auction house also respectfully escorted the two out of the gate.
"Are we going to the ruins in the Western Desert now?"
When they came to the street, Xiao Yixian looked at her man and asked.
"That's right. According to that person's information, the strong wind blowing out of the ruins space is currently weakening. At this speed, the strong wind inside will disappear in about half a month. It will take us several days to get there from Digang City, so it's better to get there earlier."
Hearing the former's question, Lin Feng's face was a little solemn and he said: "After this relic is opened, there will definitely be a fight between dragons and tigers. Before that, you'd better use the poison in the Yin Po Na Ring to break through to the eight-star Dou Zong. And I will also try to refine the bodies of the two peak seven-star Dou Zongs into puppets during this period of time."
At this point, a hint of helplessness flashed across his face.
Even in the largest auction house in Digang City, there are only three magic cores in stock taken from the bodies of magical beasts of Seven-Star Dou Zong and above.
Among these three, two are non-fire magic cores, which he can use to refine puppets.
As for the fire magic core, he wanted to keep it for use in battle.
After all, puppets have many limitations, and only when one's own strength is improved can one achieve the greatest truth.
"Then do as you say."
Hearing what the former said, Xiao Yixian nodded and agreed.
"In that case, let's go now."
After saying that, Lin Feng took the former towards the west gate of the city.
In the empty sand cave, Lin Feng sat cross-legged in the air.
With a wave of his hand, two objects flew out of the ring and fell heavily to the ground, splashing some sand.
The objects on the ground were the two Seven-Star Dou Zong peak masters that Lin Feng had killed before.
Then the former clenched his palms and emerald green flames emerged.
He then snapped his fingers and flames quickly spread out, completely enveloping the two bodies on the ground.
At the same time, it floats up and stays in the air.
The temperature of the flame was controlled by Lin Feng to a very delicate level.
It was able to burn out the residual corpse gas in the corpse without burning it.
As time passed, the scorching temperature soon made the corpse gradually turn red.
Under such scorching heat, suddenly, a very faint black gas appeared.
It floated out from the corpse and was then burned into nothingness by the green flame.
After the corpse was tempered, Lin Feng skillfully snapped his fingers again.
Two strong gusts of wind suddenly shot out.
A fist-sized hole was opened on the chest and forehead of the corpse to facilitate the insertion of the soul and magic core.
After doing all this, Lin Feng took out the souls of the two people and began to use the strange fire to burn away the consciousness of the souls.
After completing it, Lin Feng then threw them gently.
The soul transformed into a black gas dragon and drilled into the hole on the forehead of the corpse at the speed of lightning.
Seeing that it was successfully integrated, he continued to take out the tough metals stored in the ring and began to refine them.
Since Lin Feng's strength was no longer what it used to be, he had completed the refining of the two earth demon puppets in less than a day.
Looking at the two motionless silver demon puppets in front of him, emitting an aura comparable to that of a six-star Dou Zong, Lin Feng nodded with satisfaction.
The combat effectiveness of these two puppets is not as good as the two seven-star Dou Zong peak-level puppets in his ring.
But in terms of evolutionary potential, these two earth demon puppets are far superior to Yin Er and Yingshan.
After all, the strength of these two people when they were alive was not comparable to that of Yin Er and Ying Shan.
After a little hesitation, Lin Feng decided to take one of the earth demon puppets himself.
The other one will be given to Xiao Yixiang for her use later.
When in danger, you can also use the Earth Demon Puppet to hold out for a while. (End of this chapter)
