After receiving these few ghost objects comparable to the Jindan period, Li Changfeng went inside again, he knew that there were several powerful ghost objects in it. At this time, the dragon whale had not completely refined the ghost and demonic qi in his body, so Li Changfeng asked him to stay here first.

At this moment, his sense of martial arts suddenly sensed that the ghosts in this were like a tide, rushing towards him in groups, as if they had discovered his existence.

"Could it be that there is a powerful ghost creature here, far beyond the realm of Jindan. Or maybe these ghosts can be transmitted by an unknown means. Li Changfeng secretly thought, the battle just now was resolved in a short period of time, and there was no movement at all, unless the other party's cultivation realm was higher than his, it was possible to discover his existence.

"Forget it, just kill it. He shook his head, ignored the matter, and strode inside.

"Squeak squeak--"

In the blink of an eye, a group of hundreds of ghosts equivalent to the foundation building realm rushed in front of him, and the demonic energy behind them surged, the demon shadows were heavy, and the black pressure was overwhelming, and there were obviously more ghosts rushing to this side.

"Let me in. ”

Li Changfeng's face was fearless, and he strode forward, the magic banner in his hand flew up and down, and pieces of ghost things were included in the magic banner by him. He walked all the way, like a vacuum cleaner, and the monster in front of him was swept away by him.

However, as soon as he collected these hundreds, he made up for them in an instant, and these ghosts seemed to be endless, and Li Changfeng's scalp was numb for a while, and he couldn't collect them at all.

"Hmph, come on, I'm still afraid that you dead things won't make it. Li Changfeng roared angrily in his heart, and Dan Jin frantically passed towards the magic flag, and suddenly this magic flag rose against the wind, instantly magnified several times, and its power exploded.

The blue light was dazzling, and it instantly diffused out, enveloping a kilometer radius. Infinite ghosts poured into the magic flags like flowing water, and were swept away within a kilometer in an instant.

However, before Li Changfeng could breathe a sigh of relief, a group of ghosts flew out from the depths of the cave again, each of which was densely packed above the foundation, at least nearly 10,000 of them.

When Li Changfeng saw it, he immediately gasped.

You must know that just now, although it was only a short time, the Dan Jin in his body had already gone by nearly half. At this moment, there was another group, and he didn't have time to rest to recover his strength.

At this time, he could only grit his teeth and frantically destroy the Mysterious God Banner again, making it powerful.

But see, the blue light diffused out again, enveloping this wave of nearly 10,000 ghosts.

"Squeak, squeak--" The sound was endless, and nearly 10,000 ghosts struggled in the blue light.

Ten minutes later, the blue light flashed back into the long flag, and Li Changfeng suddenly sat down on the ground, panting heavily, and the strength in his body had been squandered.

Fortunately, his magic banner has been rerefined by the old dragon soul to become a peak spirit weapon, and its internal space is nearly twice larger, and its power has also increased several times, otherwise these two waves of ghost things alone will be enough for him to bear.

At this time, he could completely sense the dense ghosts in the magic flag, not 100,000 but 70,000 or 80,000, and they were almost occupying the entire magic flag space.

After a while, Li Changfeng finally recovered a little, and at this moment he didn't dare to go any further, but turned back to the outside. He had to find a way to deal with the ghosts in the magic banner first, otherwise he would not be able to collect another group.

After all, this is only a spirit weapon-level magic flag, and its internal space is limited. If it was a Dao-level magic flag, there would be no problem in directly storing hundreds of millions of ghost things. Even if it's a little bit again, a real-level magic flag, it's easy to collect a million.

"It's a pity, if only the magic banner could go one step further and become a real-level magic weapon. I don't have to worry about not being able to fit these things. Li Changfeng thought as he walked back.

"Big brother, are you okay?" At this time, the dragon whale also arrived, and he saw that Li Changfeng was a little tired, so he asked in a low voice. At this time, the dragon whale had completely refined the ghost and demonic qi in his body, but seeing that he was radiant, his mana seemed to have improved again. There is a space in his body, which can devour almost everything and use it to improve his cultivation.

"It's okay, just take a break. You came just in time, just in time to help me protect the Dharma for a while. Li Changfeng said and sat down directly on the spot, holding a spirit stone in each hand and cultivating.

Half an hour later, he finally made a full recovery. However, instead of getting up, he took out the Mystery Banner again.

At this time, memories were churning in his mind, and the memories of his past life were filtered through his mind over and over again. He wanted to find a quick way to increase the power of the magic flag, so that the magic flag could be promoted to the realm of true weapons.

It didn't take long for him to find a demonic path refining technique from his memory, which happened to be applicable to this magic flag.

It's simple, but it's bloody. It requires that more than 10,000 souls be collected at a time to be used to refine magic weapons, that is to say, tens of thousands of souls must be killed, and their souls will be taken and sacrificed alive on the magic weapons that need to be sacrificed.

"The methods of the Demon Dao are really ruthless and full of bloody killings. However, this method works just right for me. I only need to refine all the ghosts in the magic flag, and I can definitely raise the magic flag to the realm of real weapons, and maybe even break through directly to the realm of medium-grade real weapons. ”

Li Changfeng thought to himself. At that moment, he once again thought about the "Soul Sacrifice Method" of the Demon Dao in his mind, and did not dare to miss the slightest thing, until he firmly remembered those steps before he began to start refining the demon weapon.

I saw Li Changfeng holding the magic flag with both hands, and Dan Jin kept rushing into the magic flag in a strange way.

The ghosts in the Demon Banner Space suddenly boiled, and their bloody eyes turned red, and they slaughtered wildly. The scene of nearly 100,000 ghosts killing each other was really terrifying, and the tragic aura permeated the entire magic banner space.

Then, the ghosts that died in the space of the magic banner all turned into wisps of mysterious energy, which were instantly absorbed by the magic flag. This is the soul origin energy of living beings, and it is mysterious.

In less than half an hour, only a few of the tens of thousands of ghosts were still alive, and the others were either killing each other or dying in the hands of these powerful ghosts. At this time, these ghosts seemed to be a little jealous of each other, staring at each other from a distance but not making a move.

Outside the magic flag, at this time, it has been wrapped in layers of mysterious energy, and the blue light flows, emitting a faint coercion.

Li Changfeng's expression was solemn, he knew that the Demon Banner had been cultivated to a critical moment, he didn't dare to be careless, he was engrossed, and even the sense of martial arts was fully sensing the entire Demon Banner inside and outside to assist in the sacrifice, and he didn't dare to relax in the slightest.

After a while, suddenly the magic banner shook, and the few ghost creatures that were fighting each other that were comparable to the golden pill stage suddenly all exploded, and a strong energy instantly swept through the entire magic flag space.

Li Changfeng's expression moved, he knew that the most critical moment had come, and suddenly his hands quickly played all kinds of weird tricks, and the entire magic flag was controlled by the tricks and churned in the air, and the terrifying aura continued to come out.

At this time, the dragon whale also seemed to know that Li Changfeng had reached a critical moment, his expression was nervous, and he was on alert, ready to burst out and kill the enemy at any time.

"Boom"

The space of the magic banner shook violently, and suddenly there was a loud bang, and it exploded in an instant, as if the sky was splitting the earth, and the entire space was turbulent, and the spatial ripples continued to extend in all directions, for a long time.

At this moment, in the outside world, the blue light on the surface of the magic flag bloomed, and it contracted for a while, and finally it shrank violently into the entire magic flag in an instant, and disappeared without a trace.

"Haha, it's finally done. ”

Li Changfeng finally showed joy on his face, laughed loudly, put away the magic flag with one hand, and stood up. At this time, although the Lost God Banner has not reached the realm of medium-grade real weapons, it has already reached the peak of low-grade real weapons, and it is only a little bit closer to entering the middle-grade level. And its internal space has been terrifyingly expanded by nearly ten times, enough to accommodate more than a million ghosts.

However, he didn't know that just as he had just finished refining the magic flag, a terrifying aura was rising from the depths of this cave at the same time.
