It usually takes an hour to refine a ninth-level rune seal, and some complex runes take even longer.

Fu Lao still had a smile on his face, but the listed task was for Cao Fan to refine the escape talisman, the invisibility talisman, the fire talisman, the ice talisman, the sword rain talisman, the shifting talisman, the mystic breaking talisman and the defense talisman within half an hour, a total of eight kinds of ninth-level talismans, and they must all be of the best grade.

Cao Fan had long expected that Fu Lao would be shameless, but he was still shocked by the demanding requirements of the task. Of these eight runes, except for the Fire Talisman, the Ice Blessing and the Sword Rain Talisman, which have relatively few processes, the remaining five are almost the most complex types of the ninth-level rune seals. It takes a lot of time just to draw a runic diagram, and with the complicated operation of invoking spells, it is simply an impossible task.

Everything in the painting is good, that is, it is easy to get in, but it is difficult to get out. Cao Fan has now achieved the goal of improving the level of the rune path, but unfortunately he can't leave the rune realm unless he can pass the assessment of the rune elder.

Cao Fan adjusted his mood and state, but he still decided to fight.

The timer began, Cao Fan gave full play to the level of talisman making he had learned in the past year and a half, and the talisman pen became a fast-beating afterimage in his hand, and one after another spells were recited by Cao Fan and injected into the talisman diagram. Nine-level escape talisman, nine-level invisibility talisman...... One by one, the ninth-level rune seals were quickly refined by Cao Fan, and the limit speed was greatly increased again compared to the limit speed when he was originally practicing.

The seven finished rune seals were already floating in the air, and when Cao Fan quickly picked up the rune paper and was about to draw the last remaining rune seal breaking talisman, Fu Lao's hoarse voice shouted abruptly: "It's time!"

Cao Fan had already played to the limit, but after all, he was still a little short of the heat, and he failed to pass Fu Lao's outrageously demanding perverted mission requirements.

The seven talismans that have been refined are all of the best, and they fully meet the requirements in terms of grade.

Fu Lao Ke doesn't matter how high your progress is, as long as it's not 100%, then everything is not to be discussed.

The challenge experience of the Dan Realm and the Formation Realm made Cao Fan know that the next challenge of the Realm Elder would definitely be much more perverted than this time, and it was even more impossible for him to complete it.

Even so, Cao Fan could only bite the bullet and continue to impact his rune cultivation.

If you go up from the ninth-level rune seal, it will be an immortal rune.

In fact, the ninth-level rune seal is already a first-level immortal rune, and the next time he rushes through the level, Fu Lao will at least ask for refining a second-level immortal rune. Cao Fan can only continue to tap his potential and make every effort to raise the level of talisman making to the pinnacle.

The second-level immortal rune is much more difficult than the ninth-level rune seal, and the procedure of injecting the spell alone requires a huge amount of immortal power. Cao Fan's true yuan has all been converted into immortal yuan, but his cultivation is still too low after all, refining two or three second-level immortal runes, whether it is successful or not, the immortal yuan will definitely bottom out.

Fortunately, Cao Fan had a lot of pills to restore the Immortal Yuan, which could greatly reduce the waiting time. Even so, it took him a year to consolidate his rune level at the peak of the second-level immortal rune.

With the guidance and tempering of the simulated talisman system of the rune realm, Cao Fan's talisman making speed and level are definitely far superior to ordinary immortal talisman masters, but he knows that his level is still not enough in front of Fu Lao. If you go through the level at this time, you will definitely end in failure.

Cao Fan was going to practice for another half a year, so that his understanding and refining of the second-level immortal talisman would be improved to another level before he went to find Fu Lao to break through for the second time. He knew that if he failed in the second attempt, the subsequent assessment tasks would only be more demanding, and he would never be able to complete it.

"Young man, you still have four days to prepare, and after that, the level of the immortal rune assessed will be level three. Fu Lao took the initiative to remind Cao Fan for the first time. However, his words made Cao Fan as desperate as falling into an ice cellar.

In four days, it was impossible for him to raise his rune level to the point where he could pass the level.

Carelessly, the cheapness of the world in this painting is really not so easy to make. Fu Dao's cultivation has risen, but Cao Fan is also facing a huge crisis of being trapped in the painting realm forever.

The last time Cao Fan entered the middle realm of the painting, he was also so old that he couldn't pass the assessment, and finally was forced to use the Qiankun Yuan Qi, so he got out of trouble.

Fu Lao forced the law so much, Cao Fan knew that he still had to put his hope of getting out of trouble on the vitality of Qiankun this time.

Cao Fan originally obtained a gas cylinder of the Innate Spirit Treasure Qiankun from the puppet man Demon Luo Puppet, which originally contained twelve wisps of Qiankun vitality. Luo Puppet used up two wisps, Cao Fan used one wisp when he broke into the middle realm of painting, and used another wisp when he attacked the Western Wilderness, and now there are only eight wisps left.

In four days, Cao Fan spent three days continuing to practice refining the second-level immortal talisman, and on the last day, when he was looking for Fu Lao to break through, he finally used a wisp of Qiankun vitality.

The improvement of the cultivator's strength by this Qiankun Yuan Qi is all-round, from cultivation to divine consciousness to body refining, to the level of Dan, array, weapon, and talisman, all of which can make the cultivator advance by leaps and bounds.

Cao Fan was originally a cultivator of the sixth layer of Mahayana, and with the help of this wisp of Qiankun vitality, he directly rushed to the seventh layer of Mahayana, and only stopped when he reached the eighth layer of Mahayana.

In terms of body refining, Cao Fan has been promoted from the original middle stage of the Rock Realm Double Heaven to the early stage of the Third Heaven of the Rock Realm, and his endurance attribute has increased by thirty points, coupled with the skyrocketing strength of breaking through to the late stage of the Mahayana Realm, the basic combat power has reached an astonishing 1986 (375-843-382-386).

In terms of sea awareness, Cao Fan has been upgraded to three stars of Xiaocheng, which is equivalent to the level of the earth immortal, and the strength of the current cultivation of the sea knowledge that he originally possessed is no less than the level of Xuan Immortal.

In terms of Array Dao and Dan Dao, Cao Fan was originally a ninth-level Array Emperor and a ninth-level Dan Emperor, and with the help of Qiankun Vitality, all of them achieved breakthroughs. As long as he is willing, after he goes out, he can arrange a second-level immortal array and refine a second-level immortal pill.

Fu Lao's customs clearance assessment requirements came out, and Cao Fan was asked to refine a boundary breaking talisman within half an hour.

This request can only be described in four words: "madness".

Although the second-level Boundary Breaking Immortal Rune can only break through the spatial barrier of the Cultivation Realm to the Immortal Realm, and cannot break through the Immortal Realm to enter the Cultivation Realm, the difficulty of refining it can be said to be the highest among all the second-level Immortal Runes. Generally, refining a second-level boundary-breaking immortal rune, even if it is an immortal rune master in the Xuan Immortal Period, it will take at least a whole day. A Mahayana Immortal Talisman Master like Cao Fan is difficult to complete without consuming four or five days.

The most terrifying thing is that the materials for refining the Boundary Breaking Immortal Rune are very rare, and the failure rate is extremely high, and it is not necessarily possible to succeed once after refining dozens of times. Cao Fan had a deep understanding of this when he simulated the talisman system.

It is almost impossible to refine such a difficult immortal talisman in this way, and it is almost impossible to complete it if Cao Fan is only given half an hour.
