Between the two knives, Lu Chen's lifelong learning has been integrated. He has rarely been so absorbed in it, and it can even be said that he does not hesitate to damage his vitality, concentrating all his murderous aura, skill, and spirit on a certain move.

Because of this fight, once the opponent resists, he will face the weakness of the next move, overuse his strength, and always face short-term exhaustion, just like when a person breathes in, he always spit it out again.

This kind of fighting method, although it is definitely strong enough when it is the strongest, but when the power is at a low point, it is a huge flaw. Lu Chen has always disliked the flawed play.

However, in the face of the Fire Spirit Bird, Lu Chen can only fight like this, so that one blow will work.

With a bang, the knife slashed fiercely on the neck of the Fire Spirit Bird. Before the Fire Spirit Bird could even make a sound, it was cut into the neck by Lu Chen with a knife. The Fire Spirit Bird's neck was almost as thick as a normal human arm. Originally, when its strength was in good condition, Lu Chen's sword energy could not break through the Fire Spirit Bird's defense at all, but now the Fire Spirit Bird was so weak that it simply did not have enough strength to resist this sword.

With just the physical body, even a giant python that swallows the sky will definitely be injured in front of Lu Chen's knife.

With a puff, blood splashed, and the Fire Spirit Bird's body fell on the beach, with no strength at all to fight back against Lu Chen.

Lu Chen breathed a sigh of relief, and fired five more knives in a row, completely killing the Fire Spirit Bird.

A fourth-order monster, comparable to a master at the Primordial Spirit Realm, and even Nie Tianli could barely keep up with it, but now Lu Chen took advantage of it and killed it.

The blood of the Fire Spirit Bird's neck was still spraying, and Lu Chen hurriedly took out a gourd from the storage bag at the fastest speed to contain all the Fire Spirit Bird's blood.

Since the Fire Spirit Bird is a top fire-type spirit beast, its blood must contain a lot of true fire power, and even a trace of the fire of the source. For Lu Chen, the fire of the source is an unparalleled precious treasure.

Even in his previous life, Lu Chen's cultivation was a thousand times stronger than he is now, but at that time he did not cultivate the fire of the source, because he had never seen a monster with the blood of a fire-type beast. At that time, he, He just refined the real fire to an extremely pure level. Although at that point, his real fire is almost no weaker than the original fire, but it took Lu Chen six hundred years to cultivate Lihuo Divine Art to that point. equal degree.

If he didn't get the source fire, Lu Chen would only rely on refining the real fire. He wanted to cultivate to the level of his previous life. Although it wouldn't take six hundred years, at least one or two hundred years would still be needed, and now he has obtained some source fire. , maybe in a few decades, you can cultivate the Lihuoshengong to the level of the previous life.

The blood of the Fire Spirit Bird must contain a lot of source fire. Lu Chen collected a large pot of Fire Spirit Bird blood, and then used the black water method to freeze the blood.

The most precious thing of any monster is always the inner alchemy, and the same is true for the fire spirit bird. After Lu Chen collected the blood, he carefully took out the inner alchemy, and then put the fire spirit bird's body into the storage bag. .

The body of the Fire Spirit Bird is still a top-level alchemy refining material, and it must not be wasted.

Lu Chen held the Fire Spirit Bird's inner pill in his hand. After careful observation, this red inner pill, which was much larger than an ostrich egg, exuded a strong fire spirit, and the surrounding temperature had risen a lot because of this inner pill. Lu Chen had to use his profound energy to hold up the inner alchemy so as not to burn his hand.

After studying for a while, Lu Chen still sighed.

"In the end, it only contains part of Bi Fang's bloodline. The fire of the source is too mixed and impure, and the content is too low." Lu Chen is very regretful.

In this inner core, the proportion of source fire is only about 5%, and the source fire in the blood may only be 1%, which is indeed a little less.

Lu Chen thought about it, maybe because the Fire Spirit Bird's strength was greatly reduced compared to 2,000 years ago, and the fire of the source had not recovered.

The fire spirit bird on the Tianlong Continent has almost no source of fire, probably because its strength has dropped too much.

At this moment, Lu Chen's heart moved, and he raised his head with a premonition. He sensed that someone was approaching at high speed. Because the distance was too far, it was difficult to tell whether it was an enemy or a friend.

"It's probably Han Boyuan." With a thought, Lu Chen fled into the woods, like a gust of wind, disappearing.

After a while, two people came to the beach.

These two are Han Boyuan and Yun Yi.

"Senior Han, where did the Fire Spirit Bird go?" Yun Yi asked suspiciously.

Han Boyuan's face was not good-looking, and he began to search with his consciousness. After a long time, he slowly said: "The breath of the fire bird has disappeared."

"Disappeared? What's going on?" Yun Yi didn't understand. Such a big fire spirit bird, the breath completely disappeared, how is it possible?

Han Boyuan said, "There is only one possibility, and that is that the Fire Spirit Bird was killed."

"Killed?" Yun Yi never imagined that there would be such a possibility, and was taken aback. With the strength of the Fire Spirit Bird, who can kill it? What's more, Han Boyuan just asked the Fire Spirit Bird to chase and kill Lu Chen. Could it be that Lu Chen has any masters to help him?

Han Boyuan's face was gloomy. The loss of the Fire Spirit Bird was too serious for him. Now is the time to develop his power. Once the Fire Spirit Bird died, it would be difficult for him to cultivate a master of the Primordial Spirit Realm. This was a very headache.

"I felt like there was someone here just now, it should be Lu Chen, but there is no other expert." Han Boyuan frowned, wondering.

"There seems to be a great battle here, but what kind of master will appear here? And that master left after killing the Fire Spirit Bird?"

He thought that to be able to kill the Fire Spirit Bird, Lu Chen must have used some secret method to attract a master, because the previous battle between the swallowing python and the Fire Spirit Bird could be said to be very fierce, even if Han Bo was seven or eight hundred miles away at that time, He could feel the strong aura fluctuations here, but when he came over, the battle was over, and he naturally couldn't guess what was going on.

In his view, there is only one possible explanation for this situation, that is, there is a master dispatched.

But being able to kill the Fire Spirit Bird in such a short period of time showed that the master should be very strong. Han Boyuan estimated that the person should not be under him, or even stronger.

"If Lu Chen stayed here and didn't leave, it means that he didn't run very far. Senior can use his divine sense to search to see if he can catch him," Yun Yi said.

Whether it is for Han Boyuan or Yun Yi, Zhoutian Divine Art is very important. If you can capture Lu Chen, torture Zhoutian Divine Art, and rely on the power of the melting pot of heaven and earth, you can definitely improve a lot of strength.

This is also the reason why they are trying to capture Lu Chen.

However, Han Boyuan shook his head and said, "That kid's breath-holding technique is extremely brilliant. Even in my Primordial Sect, there seems to be no such brilliant martial arts. If he really wants to hide, the vast mountains are really difficult to hunt down."

"But..." Han Boyuan still said, "I have to give it a try."

Lu Chen really didn't run very far, Han Boyuan's speed was too fast, and Lu Chen didn't dare to fly with air, or even use any profound energy, so as not to cause the opponent's vigilance due to the fluctuation of profound energy. , The function of the body is like a hibernating animal, the heart stops, the breathing stops, the blood stops flowing, and the body temperature drops greatly, like a cold stone.

This is the method of silence.

However, Lu Chen has not yet entered a state of complete silence, at least he can still sense movement about ten meters away. This kind of vigilance is of course necessary, otherwise if there are monsters such as monster wolves and wild bears, won't he be eaten by monsters?

This kind of consideration is actually a bit redundant, because the annihilation method makes him look no different from a cold stone. Ordinary monsters, unless they are starving to death, will not be interested in him.

Sure enough, Han Boyuan used his divine sense to search for a long time, but still could not find any aura from Lu Chen, so he could only return in despair.

The forest was so big that Lu Chen could just find a cave to hide. It was far from possible for Han Bo to dig the nearby forest three feet into the ground. More importantly, Nie Tianli, Guo Xiuyuan and others might come over, and the situation would definitely be bad at that time.

Because if Nie Tianli and Guo Xiuyuan came over, they would definitely invite experts to dispatch them, and it would be troublesome then.

Han Boyuan and Yun Yi could only leave.

It wasn't until late at night that Lu Chen recovered from the state of silence. He is now staying in a dark cave, cold and damp. Of course, it is quiet enough, at least there are no monsters on this day.

After confirming that the two of Han Boyuan had left, he first set up a small alert formation nearby, then took out the Fire Spirit Bird Inner Pill, and began to practice on the spot to study the source of fire.

The fire of the source is much purer and stronger than the power of the real fire. If the real fire of the whole body can be cultivated into the fire of the source, I am afraid that even the fire-type treasure like the ground fire fine gold cannot stand the source. The burning of fire.

Lu Chen's current strength is still too weak, it is impossible to cultivate much source fire, but it is possible to temper his own true fire. Going a step further, not to mention the source fire, at least it should be much more powerful than the original.

He sat cross-legged on the ground, with five hearts facing the sky, holding Yuan to guard one, and placing the Fire Spirit Bird's inner pill between his legs and knees.

After two hours, fire light appeared on Lu Chen's body, and the surrounding fire spirit power enveloped him. He is fully practising Lihuo Divine Art.

The power of fire spirit provided by the fire spirit bird's inner core can be described as endless. For Lu Chen, it is impossible to fully utilize the spirit fire of this intensity in a short period of time.

He needs to digest slowly, and the fire of the source also needs to be studied and realized slowly.

In this way, time passed slowly, and more than two months passed.

His Lihuo Divine Art produced a further breakthrough, and with this breakthrough, his cultivation entered the sixth level of the Cave Profound Realm.

It didn't take much time for Lu Chen to advance from the fifth level of the cave to the sixth level of the cave, but if it was just pure cultivation, without such a treasure as the Fire Spirit Bird Inner Pill, I don't know how long it would take to advance to the sixth level. Heavy.

In the past two months, he still only refined half of the fire spirit power of the Fire Spirit Bird Inner Pill. With the efficiency of his pulseless magic, he could only do this. It can be seen that the fire spirit power of this inner pill can only be done in this way. how powerful.

Lu Chen got up and pointed out a void finger. A red flame escaped from his fingertips and shot through the granite with a thickness of two or three meters next to him, just like piercing a piece of tofu.

This is only the power of Lihuo Shengong.
