As the blue pillar of light re-landed at the place where it had first fallen, it also indicated that the Chu Demon Head had returned to the Giant Sun Sect, but the topic of the Chu Demon Head's power over the late stage cultivators of the Three Yuan Infant Realms had become a topic of conversation among all the monks on the Tianyu Continent.

After Lu Chengfeng of the Hundred Refining Sect returned to the sect unscathed, some monks thought that the Chu Demon was not the kind of big devil who was wiped out, and then later, after Fan Lizhuo of the Qingquan Temple returned to take charge of the Qingquan Temple with another face, this view was even more recognized by the vast majority of monks.

All of a sudden, the title of Chu Demon Head was removed from Chu Du's body in this way, and people were more willing to discuss what step Chu Du's cultivation could reach, there had been no God Transformation Stage cultivator on the Tianyu Continent for more than 10,000 years, Chu Du took the path of refining the body, and I don't know if his final cultivation can match the Great God Transformation Monk.

And the Giant Yang Sect, which has Chu Du in charge, has also become the sect that all the teenagers on the Tianyu Continent who want to enter the Immortal Dao want to join the most, and the Giant Yang Sect naturally recruits disciples and expands the sect in a big way, anyway, the Giant Yang Sect now almost has mastered most of the spirit stone resources on the Tianyu Continent, and no matter how many disciples it receives, it can bear it.

Originally, the three major sects with infinite scenery turned a blind eye to the rapid expansion of the Giant Sun Sect, and the sect master of the Hundred Refining Sect would even help the Giant Sun Sect refine some magic weapons, and Fan Lizhuo personally led people to kill a former Blood Sword Hall Jindan period monk who had offended Chu Du.

These things made all the monks on the Tianyu Continent understand that now the Giant Sun Sect is the master of this continent, and great monks like Lu Chengfeng can only do things for the Giant Sun Sect obediently.

As the Giant Sun Sect became more and more prosperous, the other sects felt that they couldn't hold on, not because the Giant Sun Sect bullied people with power, but that there were almost no newcomers to join these small sects, and the newcomers were all attracted by the Giant Sun Sect's rich spirit stone resources and the body refining exercises that other sects did not have.

Some small sects couldn't hold it anymore, and even chose to join the Giant Sun Sect with their entire sect!

For these things that happened outside, Chu Du, who was immersed in cultivation, naturally didn't know anything.

Time is long, 200 years have passed in a blink of an eye, this time is enough for mortals to perish a few times, and Chu Du, who had just stopped cultivating, only felt that he had just taken a nap.

In the past two hundred years, Chu Du has not only opened up all the 130 mysteries, but also refined the last source of mana.

Sure enough, as Chu Du expected, when he did these two steps, every bone in his body lit up with a jade-colored light, these bones looked white and flawless, without a trace of impurities, although these bones looked like pieces of beautiful jade, but the hardness of Chu Du's bones was thousands of times stronger than jade!

Now that Chu Du has cultivated into ice muscle and jade bones, he can smash Lu Chengfeng's Shaking Mountain Ding at will with the power of his physical body alone, and Chu Du's current physical body is already comparable to that of a monk in the 6th stage of refining his body!

Originally, the improvement of the physical body brought by opening up the 130 mysteries with Chu Du was far from reaching this step, but the refining of the last source of mana raised Chu Du's physical body to this step.

The time required for the refining of the last source of mana is the sum of the previous 12 flowers, so after refining it, the benefits to Chu Du are also the greatest, not only has it greatly improved the physical body, but the true spirit qi in the body has also been tempered to the extreme, and even Chu Du feels that it already has its own life, Chu Du does not need to control it at all, this true spirit qi spontaneously runs in the body of the Great Zhou Tian, washing Chu Du's body over and over again.

Chu Du looked at his dantian, after refining all the sources of mana, his dantian became unusually vast, and when his mind probed into the dantian, it was like entering a boundless vast world, and below this world was an ink-colored ocean composed of the source of refined mana, and Chu Du couldn't feel how vast it was for a while.

"There should be no one in this world who is wider than my dantian, if there is no cheat, you can be the same as me, then I really admire such a person. Chu Du immersed his mind in this vast dantian space and sighed as he swam around.

Chu Du's mind didn't know how long he had been swimming in his dantian before he encountered an invisible barrier to stop him from moving forward, fortunately, this dantian was not really vast and boundless, and it was impossible for Chu Du to enter the foundation building realm, and the condition for entering the foundation building realm was to fill the space in the dantian with aura at one time, and if he stopped halfway, his efforts would be wasted.

Therefore, the more sources of mana refined, the more space that needs to be filled with aura in the dantian when impacting the foundation building realm, and many monks can't absorb too much aura into the body if they don't stop at once, at this time, the foundation building pill will come in handy, and after the foundation building pill is served, it will turn into pure aura to help the monk fill the space in the dantian.

However, if you take Tsukidan, there will be a new problem, that is, if the monk's physical body is not strong enough, if a large amount of aura appears in the body at the same time, it will be burst alive by the aura, and the end will naturally be a dead end.

Therefore, most monks did not dare to refine too many sources of mana, first, the longevity yuan was not enough, and second, they were afraid that their physical bodies would not be able to withstand the pressure caused by the sudden influx of a large amount of spiritual energy in their bodies when they hit the foundation building realm.

And Chu Du doesn't have to worry about these problems at all, first of all, his spiritual power is extremely strong, which can support him to absorb the aura of the human body for a long time, even if in the end, the aura he absorbs is not enough to fill the space of the dantian, Chu Du can also take a large amount of Zhuji Dan and forcibly fill the dantian.

With Chu Du's physical body, there is no need to worry about being blown up by these aura, and the most important one, Chu Du can be resurrected on the spot even if he is burst.

After Chu Du withdrew his mind from the dantian, he took out all the Zhuji Dan looted from the three major sects, a total of 300 pills, Chu Du didn't believe that he couldn't fill his dantian after taking so much Zhuji Dan plus the aura he absorbed, if he couldn't, then eat more Zhuji Dan, with the current financial resources of the Juyang Sect, there was no shortage of Zhuji Dan at all.

Hearing Chu Du's movements, Yin Hao also got out of his body, looking at the Zhuji Dan full of places in front of Chu Du, he felt quite speechless, and it was only Chu Du's pervert who needed so many Zhuji Dan to help break through the realm, and only a pervert like Chu Du could withstand such a majestic medicinal power in an instant during the Qi refining period.

After everything was ready, Chu Du began to stuff Tsukidan into his mouth like a jelly bean while running the qi extraction, and then these Tsukidan that was swallowed by Chu Du immediately turned into an incomparably pure aura and the aura that Chu Du absorbed from heaven and earth gathered together, forming a huge aura that rushed directly towards Chu Du's dantian.

This huge aura running in Chu Du's veins only made Chu Du frown, with the strength of the current tendons and veins in his body, he could completely withstand the pressure brought by this aura.

Just when this aura was about to arrive at the dantian, the true spiritual qi in Chu Du's body spontaneously blocked the entrance of the dantian, at first Chu Du thought that this true spiritual qi wanted to devour this spiritual aura, but he didn't expect that this true spiritual qi just refined these spiritual qi again, so that these spiritual qi became free of the slightest impurity before being put into the dantian.

"Hehe, you really love to be clean!" Seeing this, Chu Du secretly praised in his heart.

Next, it was Chu Du who continued to absorb the aura and devour the Tsukidan into a rolling aura into his body, while the true spiritual qi continued to guard the entrance of the dantian to refine the impurities in the aura.

After the refining of the true spiritual qi, the spiritual energy continued to enter the dantian, and soon these silver spiritual qi covered the inky sea where the source of mana was transformed, and with the influx of more and more spiritual energy, the spiritual energy covering the ink sea was also getting thicker and thicker.

When there were only 10 Zhuji Dan left in front of Chu Du, Chu Du's face swelled with joy, because at this moment, his dantian was finally filled, and even if Chu Du controlled more aura and wanted the dantian to surge, he was squeezed out.

If Chu Du's spiritual power was strong enough, he could control his mind and observe the whole picture of his dantian at the moment.

At this moment, the dantian was completely filled with half of the source of ink-colored mana and half of the silver aura, and it looked like a black and white Taiji ball was contained in Chu Du's dantian, but unfortunately he could only see one side of this Taiji ball, and the constantly rotating Taiji ball presented a piece of Taiji plane in Chu Du's mind.
