Zhang Yifeng observed very carefully. Although Jia Wenzhe told him before that the Tie Family's Weapon Refining Pavilion was very good at concealment measures, he still felt a little uneasy.
If you want to refine and upgrade the Sky-Splitting Mark, ordinary flames will not work at all. Even the Earth Core Fire is far inferior in temperature. Only the Heaven and Earth Spiritual Fire in his body can do it.
To be on the safe side, he decided to use the Netherworld Ghost Fire, which ranked third on the Heaven and Earth Spiritual Fire List.
But using ghost fire is a very risky thing. After all, he has already had a grudge with the twenty-third prince because of this. If the twenty-third prince knows his whereabouts, he will be in danger.
Although his current strength has been greatly improved, compared with the forces of the Twenty-Third Prince and his followers, he still seems a little inadequate.
Moreover, the ghost fire of the underworld is the third-ranked spiritual fire of heaven and earth. Even if the twenty-three princes do not know about it, once other monks know it, they are likely to covet it, which will only cause many disasters.
After checking around the weapon refining room, Zhang Yifeng finally felt relieved. The Tie family had not tampered with the weapon refining room.
After setting up a concealment formation nearby, Zhang Yifeng's expression changed, and a black flame instantly appeared in the palm of his hand, beating happily.
"I wonder if this furnace can withstand the burning of ghost fire?"
Zhang Yifeng controlled the ghost fire and slowly covered the furnace, and his mood suddenly became tense.
A minute passed, until the ghost fire covered the entire furnace body, and there was no scene of furnace explosion. Zhang Yifeng couldn't help but breathed a sigh of relief. As expected, the Tie family's Tianzihao refinery room had some tricks.
As the ghostly fire burned, the huge sword body of the Sky-Splitting Mark suddenly clanged in the furnace, and a roar that seemed to come from an ancient ferocious beast came from the sword body, hitting Zhang Yifeng's mind directly, making Zhang Yifeng
I felt a surge of blood.
Immediately afterwards, a phantom of a giant beast emerged from the sword, which was the spirit of the Sky-Splitting Mark.
Yaozhu seemed to be dissatisfied with being restrained in the sword body, his eyes as big as copper bells were full of anger, and his mouth let out a shocking roar.
When it looked at Zhang Yifeng, there was a touch of human fear in its eyes at first, but then this fear turned into endless anger. It tried hard to rush towards Zhang Yifeng, but when its body
When you are about to leave the Sky-Splitting Mark, a red light will instantly appear on the huge sword.
That red light seemed to be the natural nemesis of Yaozhu. Under its pull, the extremely ferocious Yaozhu could only be slowly pulled back with an unwilling look on its face. No matter how hard it struggled, it was of no avail.
"Interesting. This is dissatisfaction with me."
The Sky-Splitting Mark has a spirit. Zhang Yifeng has not used the Sky-Splitting Mark for so long, so naturally its spirit is dissatisfied.
"Don't worry, this time, I'm just going to upgrade you."
This time, Zhang Yifeng not only planned to upgrade the Sky-Splitting Scar, he also wanted to try out what method could be used to strengthen the Sky-Splitting Scar's spirit.
Shaking his head lightly, a jade bottle appeared in Zhang Yifeng's hand.
This jade bottle contains a few drops of bright red blood, which is the blood essence of the eighth-level beast, the Earth Bear.
Zhang Yifeng wants to know, if a sword already has a spirit, what will happen if you use the Soul Blood Casting Technique to add different animal spirits during refining?
Zhang Yifeng didn't have time to look for live beasts, so he had to settle for the next best thing and use beast essence and blood instead.
Just as he thought, Zhang Yifeng opened the jade bottle, and a violent wave of energy flowed out from the jade bottle.
Zhang Yifeng poured the blood essence in the jade bottle into the furnace. He was about to use the Soul Blood Casting Technique, but at this moment, a scene that shocked him appeared.
I saw the originally angry face of Yaozhu, but when I saw the beast essence and blood falling on the sword, a look of anger and greed appeared in the fierce eyes.
Roar!
The next moment, Yaozhu roared loudly, and when the beast's essence and blood was about to fall on the sword, he rushed over in an instant and swallowed the beast's essence and blood into his mouth.
After swallowing the essence and blood of the beast, the aura on Yaozhu suddenly became stronger, and then, it showed a humane and proud look to Zhang Yifeng.
Seeing this scene, Zhang Yifeng was thoughtful.
He took out a jade bottle from the storage ring again, which contained the essence and blood of the eighth-level intermediate beast Stepping on the Snow Cloud Wolf.
When he poured the essence and blood of Tuxue Yunlang into the refining furnace, he was devoured by Tao Zhu again.
"Since you want to eat, I will let you eat as much as you like!"
Every drop of beast essence and blood contains a huge amount of energy. Although Tao Zhu is a ferocious beast, it will always be full when it is full.
Zhang Yifeng smiled faintly and took out a few more jade bottles. The contents of these jade bottles were all the essence and blood of seventh-level elementary to seventh-level high-level beasts. As for the essence and blood of eighth-level beasts, there was not much in the first place.
, he didn’t let Yao Zhu eat anymore.
Seven bottles of beast essence and blood were poured down one after another, and the result was exactly as Zhang Yifeng thought. It seemed that Yaozhu was not rejecting anyone who came, and swallowed up all the beast essence and blood.
However, Zhang Yifeng did not get angry, but instead had a smile on his face.
At this time, Yaozhu had swallowed the last drop of essence and blood and was about to show off its power to Zhang Yifeng, but its expression suddenly changed, and then a look of pain appeared in its eyes, and then it circled around the furnace.
The sword rolled over.
It was obviously full.
However, the look of pain did not last long, and Yongzhu actually fell asleep comfortably.
Zhang Yifeng finally understood one thing. As the level of the Sky-Splitting Mark increases, the spirit of Yongzhu seems to be able to swallow the blood of beasts.
After taking so much animal blood, Zhang Yifeng felt that Yongzhu's spirit had become slightly stronger.
However, it is only a trace. This shows that although Yaozhu can swallow the blood of beasts to strengthen his own spirit, the efficiency is not very high.
Shaking his head, Zhang Yifeng ignored Yao Zhu and quietly let the Netherworld Ghost Fire burn the sword body. Under the burning of the Netherworld Ghost Fire, the sword body of the Sky-Splitting Mark soon showed signs of melting.
Seeing this, Zhang Yifeng used the art of controlling objects and put the refining materials placed on the shelf into the furnace in a specific order.
After all the materials were melted, Zhang Yifeng took out the giant sword model made of deep sea mud and let the solution flow into the model from the outlet.
After the solution cooled slightly and became solid, he placed the new "Sky-Splitting Mark" on the forging table, used the meteor hammer method to the extreme, and struck the sword body with hammer after hammer.
Dang Dang Dang Dang.
The sound of forging comes and goes, like a joyful symphony.
Under Zhang Yifeng's hammering, various rare refining materials became compatible with each other.
The impurities contained in the original materials have also been beaten down to the point where no residue is left.
