After some conversation, the heart of the Retrospective Immortal Emperor became more and more shocked.

Cao Fan's Dan Dao attainments were far higher than he imagined, and even like him, he was also a super-grade elixir master.

If it weren't for being very convinced of Cao Fan's character, the Retrospective Immortal Emperor would hardly dare to believe this fact.

With the deepening of the exchanges between the two sides, the Retrospective Immortal Emperor found that although Cao Fan's Dan Dao level was much lower than him, the Dan recipes and techniques used were more perfect, and the success rate of refining the super grade Immortal Pill was much higher than his.

As a result of Cao Fan's sharing and guidance, the Retrospective Immortal Emperor was greatly inspired, and now he has full confidence to increase the success rate of refining his super-grade immortal elixir to the level of sixty percent, which is enough for him to become the first person in the Immortal Realm Dan Dao.

In return, the Retrospective Immortal Emperor also carefully instructed Cao Fan on the methods and tricks of refining the fifth-level immortal pill, so that Cao Fan could avoid many detours.

It would take about two months to go to Divine Eye Island, and Cao Fan simply hit the fifth-level elixir in the lightning boat.

According to Cao Fan's original estimate, even if he opened the time stagnation law in the core area, he would have to spend seven or eight years in it before he could refine the super-grade Yuwang Dan.

However, this time, he got the careful guidance of the Returning Immortal Emperor, which was almost the first Immortal Pill Emperor in the Immortal Realm, and the entry of refining Yuwang Dan was accelerated too much, and it took more than half a month to refine the first furnace of Yuwang Dan.

Of course, refining the Yuwang Pill is just the beginning, if Cao Fan wants to refine the super-grade Yuwang Dan, this is still far away.

In the eyes of the vast majority of Immortal Pill Kings, Cao Fan's refining of this furnace pill was already flawless, but the Retrospective Immortal Emperor still saw a trace of flaw in Cao Fan's operation, and guided him again in detail.

Although Cao Fan's simulated alchemy can also summarize the shortcomings in each round of alchemy, the effect is naturally far inferior to the on-site correction of a Dan Dao powerhouse like the Immortal Emperor.

When Cao Fan refined the seventeenth furnace Yuwang Dan, three super-grade Yuwang Dan finally appeared.

Continuously refining the seventeen furnaces of Yuwang Dan, the Immortal Emperor can also do it, but he has no way to refine the Yuwang Dan after he has just been able to refine the Yuwang Dan and only uses the seventeen furnaces to refine the super grade.

In fact, going back to the beginning of the Immortal Emperor, he had refined one hundred and seventy-eight furnaces of Yuwang Pill, and only then did the five-star elixir pattern begin to appear.

For Cao Fan's Dan Dao talent, looking back to the Immortal Emperor is really very impressed. He had always thought that he was already standing at the top of the Immortal Realm Dan Dao, but compared to Cao Fan, he realized that he was simply arrogant.

When a Dao Dan like Cao Fan entered the realm, the Immortal Emperor was sure that in less than fifty years, the other party would be able to replace him as the first person in the Immortal Realm Dan Dao.

The lightning boat carried everyone in the Heavenly Void for more than thirty days, during which time it experienced more than twenty Void Beast Clan's territories. However, firstly, there were five Immortal Emperor powerhouses on the lightning boat, and secondly, the speed of the lightning boat was indeed quite fast, and even if the void beasts along the way were vicious, they still couldn't intercept the lightning boat in the end.

At this time, Cao Fan and the others had already entered the Chaos Zone, where the immortal spirit power was extremely thin, almost like the Cultivation Realm.

The reason why Void Beasts are rampant in the Wild Zone is because the fairy spirit power is very abundant, which is suitable for the survival and development of Void Beasts.

In contrast, the Chaos Zone, which had an extremely poor cultivation environment, was naturally unattractive to the Void Beast. Since the lightning boat entered the Chaos Zone, it has never encountered any Void Beasts, let alone interceptions.

Now that the lightning boat has been controlled by Tai Geng, the Shattered Spirit Horror Dragon King who has turned into a human form, the five friends of Tianling can fully comprehend the Black Void Fusion Law Holy Stone.

However, the Retrospective Immortal Emperor was still carefully pointing at Cao Fan, and he never comprehended his own piece of Black Void Fusion Law Holy Stone.

There was a No. 1 Immortal Pill Emperor in the Immortal Realm beside him who was giving full guidance, and Cao Fan's alchemy level continued to improve rapidly, and he soon broke through from the early stage of the fifth level to the level of the late fifth level.

Looking back, the Immortal Emperor was more and more amazed in his heart, realizing that he was still too conservative in his bold judgment that Cao Fan could surpass himself within fifty years. If this kind of entry continues to develop, I am afraid that Cao Fan will be able to reach his Dan Dao level within ten years.

Looking back at the Immortal Emperor, he was not worried that Cao Fan's Dan Dao level would surpass him, after all, Cao Fan not only saved him, but also allowed him to obtain the top-grade Black Void Fusion Law Holy Stone at a very low price.

However, it was already difficult for Cao Fan to enter the cultivation realm so quickly, because after flying in the Chaos Zone for more than a month, the Lightning Boat was already about to arrive at the destination of everyone's trip, Divine Eye Island.

This meant that he could not continue to refine the pill to his heart's content under the careful guidance of the Returning Immortal Emperor.

The Evil Ward Off Immortal Emperor and the others ended their retreats one after another, and Cao Fan also stopped alchemy, because according to the flight speed of the lightning boat, in another five or six hours, everyone would be able to land on the Divine Eye Island.

As the destination approached, Cao Fan's divine consciousness began to appear one after another, and flying immortal weapons rushed to the same destination as them.

The expressions of the five friends of Tianling all became very serious, they knew that there would probably be a lot of Immortal Emperor powerhouses participating in the competition for the Divine Power Eye, and I was afraid that there would inevitably be a fierce bloody battle at that time.

At this time, the Retrospective Immortal Emperor had already replaced Tai Geng and personally piloted the lightning boat.

At the same time, the Star Immortal Emperor was also busy checking the Immortal Array on the lightning boat.

It was only at this time that Cao Fan knew that the Xingchen Immortal Emperor was actually still a sixth-level peak array emperor, which was even better than the formation level of Xue Zheng, the first immortal array emperor of the Taixuan Emperor Sect.

The Lightning Boat was flying at high speed, but was blocked by a fierce battle that was taking place in front of it.

This battle involved more than twenty immortal cultivators, and one of them clearly had a numerical advantage.

There were as many as seventeen immortal cultivators on the dominant side, and they were besieging the other seven immortal cultivators who were covered in blood.

"Doom Immortal Emperor, we have no grudges against you people in the Northern Heaven Domain, why do you want to put us to death?" Among the seven besieged Immortal Emperors, an Immortal Emperor wearing an ochre-colored Taoist shirt, a cloak with a disheveled head, and a blood-stained face blocked the opponent's Immortal Treasure attack with a sword, and shouted at a purple-haired Immortal Emperor who was haunted by evil aura on the opposite side.

This cloaked Immortal Emperor Cao Fan actually recognized that it was actually the Sect Master of the Holy Cloud Emperor Sect of the Middle Heaven Domain, the Tianmu Immortal Emperor.

When the Immortal Alliance was held, although Cao Fan did not show up, his divine sense was released from outside the Taishang Nine Realms, and he saw the situation outside clearly.

Moreover, this kind of divine consciousness released through the Five Elements World has almost no energy breath, and it is extremely difficult to perceive, at least the Immortal Emperor who has cultivated to the eighth level of the Immortal Emperor has not noticed it.

"Hehe, there is only one Divine Power Eye, so naturally the fewer people who are fighting for it, the better. The people of your Middle Heaven Domain don't take it upon themselves to wade through this troubled water, don't blame us for being ruthless!" the purple-haired Immortal Cultivator, who was known as the Doom Immortal Emperor, said coldly.
