The breakthrough had come to an end, and Lang Feng had the leisure to pay attention to things other than the acupuncture points at this time, and he focused his attention on the sea of qi.

At this time, due to his successive breakthroughs, especially when he entered the Star Protector Level, the Qi Sea had undergone earth-shaking changes compared to before, at least in terms of size, it was more than twice as large as after he broke through the Star Warrior.

If it used to be a small pond, now it is a small lake, and in the very center of this small lake there is now a black whirlpool that is constantly swept into his gaseous internal force, and then throws out some transparent droplets.

But these droplets are not transparent when they are thrown out, but only when they appear outside the vortex.

That is to say, when they are in the whirlpool, they have color, and the internal force with color means that they have attributes, but before, unless Lang Feng used his spiritual root, the internal force was transparent.

Penetrating his soul thoughts into the very center of the whirlpool, a diamond-shaped diamond-shaped object appeared in his senses, and all the energy was absorbed and transformed into ordinary internal force. Then, after being vortexed into the diamonds, they become liquid.

Lang Feng passed the picture in the sea of qi to Xinghe, hoping that he could solve his doubts, but he didn't expect the little guy to appear directly in the whirlpool of the sea of qi in a flash.

"Boss, congratulations, this is the internal force crystal nucleus that will only be formed after the Great Star-Lord level, and it can improve the internal force transformation efficiency and response speed!"

"Let's not talk about this for now, how did you get to my sea of qi!" Lang Feng was stunned by the scene in the induction, and when he found that there was indeed no shadow of the galaxy in the space of the Soul Eye, he immediately began to ask him the reason.

"Well, I don't know, the moment you reach the Star Guardian Cultivation, I seem to have a better understanding of your body, but you don't have to worry, I will still rest most of the time like before, and I won't snoop on your privacy!"

Xinghe spread his hands, saying that he didn't know why. In the end, this question had to be put aside for now, after all, Xinghe was his own person, and it was not a matter of concern that he had some weird abilities.

"What did you just say, this thing is an internal force crystal nucleus that can only be formed at the Great Starlord level, so how should it be used?"

Since it is something that can only appear at the level of the Great Starlord, why does it appear now, Lang Feng was very surprised in his heart, but this did not prevent him from having a heart that wanted to peek into the mysteries of the Great Starlord with the cultivation of the Star Protector.

"How to use it? It's still the same as using internal force before, but if you want to have a Great Star-Lord-level internal force response speed now, you can try to separate some spiritual root qi into this crystal nucleus, and build a hybrid spiritual root cloud in this crystal nucleus!"

Building a Mixed Spiritual Root Cloud? Lang Feng was a little eager to try it for a while, but without a teacher by his side, everything had to be explored by himself, and he was still a little apprehensive.

Seeing that his boss hesitated a little, Xinghe's body blurred for a while, and finally turned into a somewhat illusory crystal nucleus, and then a small piece of green, black, purple, red, yellow and other colors of spiritual root qi appeared into this vague crystal nucleus.

Eventually, a colorful swirling cloud appeared at the very core of the simulated crystal nucleus, and as it continued to rotate, more and more misty internal forces were converted into droplets and thrown out, and the entire crystal nucleus was like a source of liquid internal forces.

"Boss, do you see it clearly, just get it like this!" Xinghe's hand made Lang Feng stunned again, he was surprised that he had broken through this time, and it seemed that Xinghe had obtained more strange skills.

"Seeing clearly, I'll do this, right?" Although it was a question, Lang Feng had already begun to try, he first tore off a small piece of wood attribute from the Spirit Root Cloud of the Star Soul World and channeled it into that internal force crystal nucleus.

Of course, this tear, he has to endure very strong pain, the kind of pain that goes straight to the depths of the star soul, the galaxy cannot demonstrate, so for Lang Feng, the whole process is very difficult.

In Lang Feng's rough estimate, it probably took him nearly a day of hard work to make a new colored cloud like a spiritual root cloud appear in his internal force crystal nucleus.

When the colorful clouds formed, Lang Feng immediately had a very strange feeling, as if he could clearly feel the flow of every drop of internal force, even their emotions!

Of course, because he was in too much pain, he didn't have the first time to have a deeper communication with these internal forces, he just wanted to take a few breaths now to relieve the pain of going deep into the star soul.

Just when Lang Feng was advancing by leaps and bounds, the scene outside the Heavenly Coffin had also undergone some very huge changes, first of all, the energy in the energy gathering array suddenly became very full, as if the energy in this piece was no longer imprisoned, and it was easily taken away by the energy gathering array at once.

In addition, the yellow mist on the Huangyan River no longer appeared, and some pale yellow bone meal began to slowly settle towards the bottom of the river.

And those star beasts began to rush towards the gathering array like a cat that smelled fishy, because the gathering array itself has a defensive function, so every time the star beast rushed to within twenty meters of the gathering array, it would take a lot of damage.

However, even so, those star beasts still refused to leave, and maintained a high degree of activity around the gathering array, after all, the energy around the gathering array was also quite considerable.

Shang Qing didn't expect such a scene, and after returning to the gathering array, he told everyone in the team about it, so they studied a training plan.

Those star beasts around the energy gathering array have become the sparring partners of the team, and the people of the entire team are not poured out of the nest every time, one at a time, and those star beasts are not killed, they are directly seriously injured and return after completing their tasks, and this is the same, a good cycle is formed.

Just when the team was training aggressively, Lang Feng completely relieved himself, and unceremoniously began to frantically absorb those ice and fire energies, until he turned his qi sea into a real internal force lake, and the liquid internal force was almost all over the entire qi sea before he stopped.

Feeling the surging energy in his body, Lang Feng was confident that if there was a mountain in front of him now, he would be able to drill a big hole in it with one punch.

It was only at this time that he had the heart to pay attention to those liquid internal forces that he could clearly sense, and when he wanted to use one of the internal forces in the past, he also needed to communicate with the star soul first, and then borrow the cloud of spiritual roots to transform the internal forces.

But now he only needs one thought, the attributes in the spiritual root, he will easily use it, not only that, but he can also mix two, three, four, or even all of them.

Finally, as his sea of qi was completely filled with liquid internal force, this heavenly coffin space actually began to collapse, which forced Lang Feng to start fleeing from here directly.

When he reappeared at the entrance of the Heavenly Coffin, the supernatural patterns on the entire coffin emitted dazzling light as if it had been ignited, and the Heavenly Coffin itself was still shrinking at a speed that was visible to Lang Feng's naked eye.

When the coffin shrank by half, the Yanhuang furnace that followed Lang Feng out suddenly moved, only to see that it suddenly became more than one person tall, and then suddenly sucked the coffin into the furnace.

"Phoenix Bird, give me an explanation!" Lang Feng was a little unhappy, he was about to study those lines, and he always felt that those lines would be beneficial to his future entry as a soul master, but he was suddenly interrupted by the Yanhuang Furnace.

"Master, I'm going to refine this heavenly coffin, maybe you can give me a small boost, and I still have gifts to give to my master in the future! But I still need the master's help!" The phoenix bird showed a head from the heavenly coffin, and his eyes were full of surprise.

"Okay, I don't know if it's my blessing or my disaster to have such a machine spirit like yours!" Lang Feng immediately sat down in front of the Yanhuang Furnace, and then used the power of the star soul to urge the power of the fire essence of the Yanhuang Furnace and began to refine the mysterious heavenly coffin.

I don't know what kind of material that heavenly coffin was made of, and when Lang Feng increased the firepower to the maximum, it only turned red without a trace of melting.

"Hey, I don't believe you!" Lang Feng was a little suspicious in his heart, but at the same time, he also launched a ruthless attack, and immediately began to add his internal force to it, at first the coffin did show signs of melting, but in the end it remained at the boundary of whether it would melt or not.

Lang Feng had completely transformed his internal force into the fire system at this time, but even so, he could only do this, and the phoenix bird was not idle, and he was also spitting out a little bit of that very powerful essence fire from time to time.

"Why do you always feel that I have no spare strength, but I have obviously done my best?" Lang Feng was surprised, because there was always a strange feeling enveloping him, that is, he could melt this heavenly coffin.

"Heavenly coffin, heavenly coffin! Ha, I remembered!" Lang Feng slapped his head suddenly, and the next moment the internal force output became the energy of the dual system of ice and fire, and it was also the energy of the same origin of ice and fire.

At this moment, the coffin immediately had a strange change, and after a while, a drop of golden molten slurry fell into the Yanhuang furnace.

When the drop of molten slurry had not completely fallen, it was immediately swallowed by the phoenix bird with its neck stretched out, and after the phoenix bird swallowed the drop of molten lava, some changes immediately underwent in its body.

Although this change was very insignificant, Lang Feng knew that this change did exist, so he immediately helped Phoenix Bird refine that molten slurry with confidence.

It seems that the molten slurry is only refined from the solid state of the heavenly coffin, and in the process of melting the entire heavenly coffin, no impurities appear, just like pure ice has turned into water.

As drops of molten slurry fell into the phoenix bird's body, Lang Feng slowly discovered where the change came from, and it was actually the phoenix bird that slowly had a condensed body.

If the phoenix bird's previous state was like a star soul body, then it is now giving birth to a physical body, a very powerful physical body.

This made Lang Feng's motivation more sufficient, although the consumption of internal force was also very large, but he did not care about the cost, regardless of the beginning of the consumption, because he wanted to see a complete spirit phoenix bird.

With Lang Feng's unremitting efforts, the heavenly coffin finally shed the last drop of molten slurry like melting ice and snow, and the phoenix bird's body seemed to have become complete.

However, in the end, Feng Niao complained to Lang Feng, saying that with another such coffin or the same material, his body would probably be able to be reassembled.

Although there was a trace of regret in his heart, this did not prevent Lang Feng from asking the phoenix bird about its current ability, and he was startled when he asked if he didn't know, because the phoenix bird told Lang Feng that the Yanhuang furnace now had a new ability, that is, the Star Soul Weapon Rubbing.

The so-called Star Soul Weapon rubbing refers to the fact that it is within the scope of Lang Feng's strength, as long as he refines a Star Soul Weapon through the Yanhuang Furnace, then the next time he refines it, he only needs to put the materials into it, and the other work can be completed by Feng Bird.

"Wow, liberated, this is simply a star soul weapon assembly line!" Lang Feng felt that this was a worthy carnival, and immediately wanted to go to the team members to share it with them, only to find that the star beast group of Wuyang and Wuyang had actually surrounded the gathering array.

At this time, the energy gathering array was frantically extracting energy from the Huangyan River, and it seemed that those energies had become easy to absorb all of a sudden.

When he saw that there were people fighting in the herd, he immediately put his mind at ease, this was exactly the scene he was expecting, and there was enough energy to improve his cultivation, and there were powerful star beasts as sparring partners to improve his actual combat experience.

"Master, don't worry, I said, there are gifts for you!" Seeing that Lang Feng was about to rush towards the beasts, the phoenix bird immediately stopped him, his refining was not yet completed, and he still needed the help of this master.

"Oh! gift, what is it, take it out quickly, I like the gift the most!" Lang Feng rubbed his hands and looked at the phoenix bird.

Following the guidance of the phoenix bird, Lang Feng once again set his eyes on the Yanhuang Ding, only to see that in the space inside the Ding, one large, four small and five skeletons were being smelted on the fire, making a crackling sound from time to time.

"Is this a gift?" Lang Fengbing didn't want to see these five bones, who would play with such bones, how infiltrating it is.

"Boss, don't ask what this thing is, you finish its smelting first, and then I'll help you get some materials back!" After saying that, the phoenix bird immediately flew out of the Yanhuang furnace, drawing circles in the air constantly, and after a while, a tornado was formed.

However, this tornado is very peculiar, it only rolls up the yellow bone meal in the river and throws it into the furnace, not even a drop of river water.

"You're going to refine this river!" Lang Feng saw that the phoenix bird didn't let go of a trace of bone powder, and immediately increased the fire, he also wanted to see what this phoenix bird gave him in the end.
