After purchasing the best Thousand Soul Banners, Yu Ke transferred the Ghost Sea army that was originally loaded in the Hundred Soul Banners to the Thousand Soul Banners one by one.

Since both the deity and the ghost clone broke through to the Vortex Liquid Stage, and their divine consciousness also increased significantly, it was now very easy for the Ghost Sea army to drive.

With the Thousand Soul Banners in hand, the upper limit of the Ghost Sea Army was immediately expanded to nine thousand nine hundred and ninety-nine, and since the top-grade Hundred Soul Banners were upgraded to the top-grade Soul Banners, the divine thoughts required to control a single Yin Soul were also reduced. The almost cultivated ghosts and ghosts can be easily controlled by more than a thousand.

Buying soul flags, but also buying demon spirits and wild ghosts, is another big expense. The Yin Yin Grand Canyon can be broken through, and there is only one chance to enter the valley during the spin period. Yu Ke is now only one layer of the spin liquid, and it is undoubtedly a waste of opportunity to enter so early, and it is more cost-effective to wait until the middle and late stages of the spin liquid.

I had no choice but to spend more than 330,000 spirits to acquire more than 20 wild ghost guards and more than 1,300 ghost pawns with strength above level 6, so that the number of yin ghost objects in the Thousand Soul Banners suddenly increased to about 2,000.

It cost more than 700,000 souls to buy a Thousand Soul Banner, and Yu Ke's pockets suddenly deflated a lot.

In the next three months, Yu Ke stayed in the Immortal Refining Pavilion, waiting for the news of the Yin Fire collection on the sect's side, and cultivating the second layer of the Forging Divine Technique, even if the cultivation could not be improved for the time being, it could not be idle, and the Heaven Conquering Conference after three years could not be neglected, Yu Ke also wanted to take the opportunity to weigh the super genius disciples of other major forces.

The progress of the Divine Forging Technique is good, but the second layer is much more advanced than the first, most of the Yin Netherworld Demon Sect cultivators will be stuck at this level, even if the cultivator is successful, it will take at least ten years, Yu Ke is quite talented in divine thoughts, and it is impossible to cultivate it in just a few months.

In the second month of the opening of the Immortal Refining Pavilion, Xie Wei successfully advanced to the Liquid Rotation Period with the help of a Tong Xuan Pill, and after all, he did not use Meng Yang's share, after Xie Wei came out of the customs, the Alchemy Workshop finally had someone in charge, and Meng Liu, who had already cultivated to the peak of the Qi cultivation period, couldn't wait to pinch his share of the Tong Xuan Pill and start the retreat.

In addition, after a period of dormancy, the five natal ghost servants also woke up one after another, and they all advanced to the ghost guard level.

At this time, after Yu Ke finished cultivating the Divine Forging Technique, a Qi cultivation cultivator from the Yin Netherworld Demon Sect came over.

"Uncle Yu Ke, my nephew is instructed by the Contribution Hall to inform you that the Yin Fire you have offered has been collected, please ask Uncle Shi to raise five hundred and thirty spirits in a year and go to the Xuansha Valley Contribution Hall to collect it. The monk respectfully finished the message and departed.

"The sect's movements are quite fast. Yu Ke smiled slightly, "But this Futu Vajra Demon Buddha Book is really a bottomless pit, and a single fire requires more than six million spirits." ”

When Yu Ke was summoned, Si Tianxin also got the message brought by Yanliu, asking her to rush back to Xuansha Valley as soon as possible.

So the two entrusted Xie Wei with full authority for the Immortal Refining Pavilion, which had just opened, and returned to Xuansha Valley together.

In the Xuansha Valley Contribution Hall, the half-dead Jindan Elder looked at the five hundred and thirty high-grade spirit stones handed over by Yu Ke in surprise, and was stunned for a moment before waving his hand to accept it.

"Boy, it seems that it is rumored that you have earned nearly 10 million souls in Dabi, which is true. The old guy stared at Yu Ke with burning eyes: "But you have to be careful, you kid is a big fat meat now, how many people are waiting to kill you." ”

The balance of the five hundred and thirty spirits, plus the previous one hundred spirits warranty, that is six million and three hundred thousand spirits, after experiencing the opening of the store and the purchase of the industry, as well as the purchase of a thousand soul flags and ghost soldiers, Yu Ke now only has about a hundred high-grade spirit stones left in his hands, which is still the income after selling three Tongxuan Pills.

"Kill me? I still want to kill people. Yu Ke smiled indifferently and said, "The spirit stone is handed over, and I want the yin fire." ”

"What's the hurry, do I dare to be greedy for you?" the old guy snorted coldly, waved his hand and took out a fist-sized small bottle made of unknown crystals, and a dark green flame with a little red blood light was beating in the bottle.

"Candle Dragon Yin Fire?" Yu Ke was overjoyed in his heart, and snatched the Yin Fire from the old man's hand. Candle Dragon Yin Fire, ranked ninth in the Yin Fire List, is said to have evolved from the soul and flesh of the ancient fierce beast Candle Dragon after the fall, with endless resentment and ferocity, and after the cultivation of ghosts, it is extremely powerful against the enemy.

"Boy, this candle dragon yin fire was taken out of the treasure house of the sect, there are only two copies in total, and the previous one has been taken away. This one sells you 6.3 million spirits, which is considered cheap for you. The old guy said with a hard face: "I don't know which one above helped you, and after you couldn't find it, you directly ordered to open the treasure house of the sect, hum!"

"Oh, so there's still this stubble. Yu Ke smiled slightly, and he also understood in his heart that another candle dragon yin fire was afraid that it had already reached Si Tianxin's hands, although the yin fire thing was extremely precious, it was not unique.

After collecting the Yin Fire, Yu Ke returned to the cultivation residence of the Xuansha Valley, summoned the Yaksha Ghost Servant, and directed it to refine the flame of the Candle Dragon Yin Fire.

It took half a month of hard work for the Yaksha ghost servant to completely refine the fire into the body and reach the realm of unity. With the urging of the ghost servant's mana, this candle dragon yin fire also exerted its due power, and now without the Thousand Soul Banners, Yu Ke himself has to retreat when he encounters the Yaksha ghost. According to Yu Ke's calculations, with the Yin Fire, even a monk at the third or fourth level of the Vortex Liquid Stage may not be able to please the Yaksha Ghost.

After the Yaksha ghost servant became proficient in the Yin Fire Imperial Envoy, Yu Ke began the cultivation of the "Futu Vajra Demon Buddha Book".

Under the urging of the ghost servant, the blazing yin fire carefully skewed into the dantian qi sea along Yu Ke's meridian and body, and began to refine and transform mana.

The burning sensation came, and Yu Kelian swallowed the prepared elixir and the Yin Han surname treasure in his abdomen, and began to cultivate according to the operation route of the exercises.

Under the tempering of yin fire, if there is no corresponding spiritual nourishment and relying on one's own cultivation to resist, it is no different from looking for death.

Nearly seventy percent of the spiritual power transformed into spiritual pills and spiritual objects has been refined, and with the increase in the types of yin fire and the enhancement of the mana of the ghost servant, this proportion will be even higher. At that time, the resources consumed by cultivation for each level of promotion were more than ten times and dozens of times that of monks in the same period.

In this case, if you want to maintain the same level of cultivation as other monks, you need to have strong financial resources.

After cultivating for half a month, Yu Ke converted all the previous mana into the mana of the "Futu Vajra Demon Buddha Book", not only did the mana not increase, but the liquid mana vortex in the dantian qi sea also shrank by nearly thirty percent.

Of course, because the mana has become more refined, the strength has not decreased, but has increased.

There has also been a lot of progress in body refining. After tossing around like this, you can really get on the right track of cultivation.
