Flag, also known as soul flag, it is different from other weapons, soul flag, and the soul of the human soul blend, close union, the soul of the flag, the soul, is the root of the flag.

Only those with a strong soul are suitable to use the soul banner as a weapon, the soul is not strong, the power of the sacrifice banner is limited, and it is impossible to achieve the unity of the soul and the soul flag.

Digesting the memory, Lin Feng opened his eyes, looked at the death, and said, "This refining soul banner also needs to use the Empty Tung Tree." ”

"I have. Liwu said calmly, making Lin Feng's eyes slightly condensed and looking at Liyan.

Lin Feng, it was the first time he saw the number of empty tung trees, but according to this memory, the empty tung tree has a spatial level, and many storage bags are also refined from the branches and leaves of the empty tung tree, and the empty tung tree itself is also a kind of space tree, which can be used to refine treasures with a spatial level, which is extremely precious, and he is very calm to tell Lin Feng that he has.

"Lin Feng, you don't have to worry about the materials for refining the soul flag, as long as your soul liliang is not a problem, refining the soul flag, it is not difficult, the difficult thing is the compatibility between your soul liliang and the soul flag. ”

Li Yan spoke again, Lin Feng's eyes flickered, he had the Remnant Soul Heavenly Technique, he was very suitable for refining and using the Soul Banner, seeing a memory of this Soul Banner, his heart was also quite moved.

"I'll do my best. ”

Lin Feng said to Liyan, Liyan nodded, and said, "Without further ado, then we will start refining the soul banner now, you think about it, whether you want to refine the flame soul banner or other soul flags, with your soul liliang, there is no problem in refining the ghost flag." ”

"I refine the Flame Soul Banner. ”

Lin Feng did not hesitate, and said decisively, leaving the funeral just nodded, and did not say anything.

His heart moved slightly, and many things of refining flags appeared in front of Lin Feng, the most important of which was a red tree, with the breath of space, the empty tung tree.

The empty paulownia tree is only one meter high, which seems to be tiny, but as soon as it is moved, the empty paulownia tree actually stretches wildly, and soon turns into a towering red tree, and even touches the top of the fortress.

"It's amazing. Lin Feng's eyes condensed slightly, this empty tree is a kind of space tree, even if it is no longer nourished, it still contains the meaning of space.

"Will you refine it, or will I come?" asked Lin Feng, who stared at the Empty Tree Tree.

"Alright, I'll help you. ”

Lin Feng's heart moved, and suddenly, on his body, a blazing flame burned up, and the Yang Fire True Yuan was filled with infinite blazing meaning.

"Burn!"

Lin Feng drank in a low voice, and the rolling yang fire rushed towards the empty tung tree, and then climbed towards the empty tung tree, and the flames spread towards the entire tree, and soon, all the empty tung trees were Lin Feng's yang fire.

However, it was burned by the flames, and the empty tree only made a crackling sound, but it did not burn at all.

The flames can't even burn a tree, it's very strange.

At the same time as burning the Empty Tung Tree, a powerful soul aura spread out from Lin Feng's body, and then it also rushed towards the Empty Tung Tree, infiltrating into the entire Empty Tung Tree.

Li Yan watched Lin Feng refine the Empty Tung Tree from the side, he didn't intervene, just stared at Lin Feng from the side, seeing Lin Feng's refining of the Empty Tung Tree, his eyes also showed a strange color, Lin Feng, whether it was the control of the flame or the use of the soul liliang, was very accurate, he should have understood the art of refining, and it was not the first time to refine treasures.

That way, the whole process will be much easier.

Moreover, the refining of this soul banner is not too difficult, the real difficulty is to use the soul to open up the space of the soul banner and integrate the soul liliang into it.

Time passed slowly, and in the blink of an eye, half a day passed, and Lin Feng and Liyan were still in the ancient castle, not going out a single step.

And at this moment, in the ancient castle, in addition to the strong yin wind aura, there is also a terrifying blazing aura, and the entire fortress is full of flames.

In the deepest part of the ancient castle, Lin Feng and Liyan were still sitting there, Lin Feng at this moment had his eyes closed, his brows were tightly furrowed, and there was even a paleness on his face.

For the refining of the soul flag, it has reached the most critical moment, success or failure is in this move, as for the empty tree in front of him, it has been refined at this moment and turned into a flag-like thing.

"Fire!"

Lin Feng drank in a low voice, and suddenly a terrifying flame aura rolled out of his body, and the flames frantically headed towards the faint wisp of rudimentary soul flags.

"Boom!" a buzzing sound came out, and all the flames on the soul banner were there, but the flame didn't seem to want to burn the soul flag, but frantically headed towards the tiny gap in the soul flag.

"The empty paulownia tree、This is a gap in space, with the liliang of flames, it is difficult to break through it。 ”

Lin Feng whispered, and then his heart tightened, and an incomparably terrifying soul power violently headed towards the soul flag.

It was as if there were thousands of invisible souls, entwined with flames, frantically drilling into the gaps in space.

"Snort, snort......" A soft sound came out, the space gap seemed to be torn apart, thousands of souls and flames all seeped into it, and the flames on the entire soul banner disappeared, but on the soul flag, there was a terrible flame breath, there was no flame, but the flame breath still shook people's hearts.

"Sacrifice the soul!"

Lin Feng snorted, his face was suddenly as pale as paper, and the formed soul banner trembled wildly, and then shrank again, and the banner turned into a banner, as if a gust of wind could blow him away, but in the banner, there was a terrifying will of flame.

"Melt!"

Lin Feng gritted his teeth and snorted, and a whistling wind of flames came out, and the banner in the void automatically rose up.

"It's done. ”

At this moment, Lin Feng's face was pale, but his heart was full of joy, a feeling of flesh and blood was born in his heart, at this moment, he could clearly feel that he and this soul flag, as if they were integrated, this was the first time Lin Feng had this feeling about weapons, as if the soul flag was his hands and feet.

The jade of memory that he was given by the death and the memory of refining the soul banner contained in it were indeed true.

With a move of his hand, the soul banner shrank, and turned into the size of a palm, appearing in Lin Feng's hand, extremely mysterious.

"The Empty Tree is really magical!"

Lin Feng whispered in his heart, put away the soul flag, and turned his gaze, and then Lin Feng saw that Li Yan was looking at him with a smile.

"Lin Feng, the soul banner you refined is good, you don't need to be so hard to face the wolves in the future, the soul banner is rolling, and the wolves will all be caught in the flag. ”

Lin Feng nodded, still feeling a little weird, leaving the dead, why should he help him refine the soul flag?

"The refining of this soul banner is all your credit, xiexie, if you need anything, I can give it to you, even if it is an exchange. ”

An excited light flashed in Li's eyes, and he said, "Okay, first of all, I need your ability to cultivate the soul, and secondly, I need your storage stone ring and everything in it, so I should take these as the reward I gave you the technique of refining the soul banner and helping you refine the soul flag." ”

"Huh?"

Lin Feng's gaze froze, staring at the Soul Flag, this was to exchange everything he had for the soul flag, although the soul flag was precious, but it was not precious to this extent, and the Soul Remnant Heavenly Technique was much more precious than him.

It seems that he is gone, knowing that he has the means of cultivating the soul.

"Are you too greedy?"

Lin Feng didn't get angry, he looked at the death calmly and said.

Li Yan shook his head lightly, and said very indifferently: "Don't be greedy, I didn't take all your soul, I already let you go, besides, I gave you the soul banner and the art of refining the flag, which is already a favor to you." ”

Lin Feng just sat there, looking at the death beside him, and didn't speak.

Liyan also looked at him, and also said nothing.

"Boom!"

Suddenly, a terrifying killing intent bloomed out, and Lin Feng's body instantly rose into the air, and the killing aura on his body soared into the sky.

With his palm raised, Lin Feng slashed directly into the void, and a sword light bloomed in the ancient castle, slashing towards the Death.

"Humph!"

Liyan snorted coldly, and a yin wind seeped out of his palm, eerie and terrifying, as if thousands of ghosts were roaring.

A loud rumbling sound came out, and I saw Lin Feng's body shoot out in a volley, rushing out towards the exit place, and disappearing into the ancient castle in an instant.

The light of excitement in Liyan's eyes became thicker and thicker, and with a heavy step, his body flashed out, bringing a gust of yin wind.
