After Luo Yu returned to the cave, he retreated and began to make plans for his next year, Luo Yu was not too worried about the pills needed for cultivation, and now the low-grade Jingyuan Pill was as useful to himself, so he only needed some half-spirit medicinal materials Blood Deer Ear, and the spirit stones and pills on Luo Yu's body were not a big problem to support this year.

And now Luo Yu has a superb magic weapon in his hand, and the problem of the magic weapon can not be considered, as for the talisman, Luo Yu has used up his only two intermediate talismans last time, and now he has a few low-level talismans in his hand, to be honest, for the attack power of the talisman, even if it is an intermediate talisman, it is difficult to cause great damage to high-level immortal cultivators, and the price of the intermediate talisman is also very expensive, so the problem of the talisman, Luo Yu decided to buy it if he can meet some better intermediate-level talismans in the future, just like the Huoyun talisman last time, although it is also an intermediate-level talisman, but in terms of attack power, I am afraid that it is also a first-class product in the intermediate-level talisman, but like that kind of opportunity, it would be nice to meet it once!

After a little silence, Luo Yu left the cultivation room and walked to the elixir room next to it, although this elixir room is only a false name now, but it is just right for him to come and practice this impermanent ghost corpse.

After Luo Yu came to this elixir room, he snapped shut the small door of the stone room, and then gently patted the storage bag, and took out two identical ghost flags from it, this is the two soul refining flags that Luo Yu recovered after killing the two black-robed people, although these two items belong to the magic weapon, but after Luo Yu studied the Hundred Soul Sutra, he found that simply driving the ghost corpses inside does not necessarily need to practice the demon path exercises.

Therefore, it is best to be able to turn the impermanent ghost corpse into one's own use, after all, no one will dislike their own attack methods.

Luo Yu raised his hand and shot out two spiritual powers, and rushed into the ghost flag, "Woo!" Two gloomy voices came out from the ghost flag, only to see two black gases shoot out of the ghost flags in a flash, circling around Luo Yu slightly, then dissipating the black gas, revealing the two impermanent ghost corpses wrapped in the black gas, the two ghost corpses are blue-faced fangs, as soon as they came out, they looked fiercely at the only living person in front of them, Luo Yu.

"Hmph!" After Luo Yu snorted coldly, he immediately recited the control spell in the Hundred Souls Sutra in his heart, and transmitted it into the ears of the two ghost corpses through spiritual awareness, and suddenly, a trace of pain appeared on the terrifying face of the ghost corpse, and the fierce light in his eyes also subsided a lot.

These two ghost corpses, one of them is the strength of the eleventh layer of the Qi training period, and the other is only the tenth layer of the Qi training period, the yin qi around the body is obviously not as thick as the eleventh layer of the ghost corpse, and one of the arms of this ghost corpse is still blurry and abnormal, it seems that after Luo Yu used the Biling Han Halberd to cut it off last time, it has not fully recovered until now.

Seeing this scene, Luo Yu's face suddenly wrinkled, this ghost corpse with a cultivation of only ten layers of qi cultivation was originally not very important to him, and now he still looked injured and unhealed, Luo Yu looked at it for a moment, and immediately took out the jade slip that recorded the "Hundred Souls Sutra", and his spiritual sense sank into it and watched, as if he was looking for something.

After a short while, Luo Yu withdrew his spiritual sense, and said with a hint of discoloration on his face: "Sure enough, these impermanent ghost corpses are still condensed by the Yin Soul Xuanyin Qi in the final analysis, and they are still very different from the real corpse refining, if they are really refining corpses, then they may not have a way." ”

Just now, Luo Yu carefully read the record of impermanence ghost corpses in the Hundred Souls Sutra, and sure enough, he verified the conjecture in his heart, these ghost corpses are gathered by yin qi, and ghost corpses can only continue to grow by absorbing yin qi, so Luo Yu will be whimsical, he plans to use the innate true fire of the foundation building period monk to refine Wang Fu's ghost corpse and the yin qi in his ghost flag, and then let the ghost corpse of the eleventh layer of the qi training period suck those yin qi, so according to Luo Yu's estimate, if this method is feasible, then sucking all the yin qi of a ten-layer ghost corpse in the qi training period can definitely make another ghost corpse break through from the eleventh layer of the qi training period to the twelfth layer of the qi training period！

Because this ghost corpse is simply formed by the convergence of yin qi, as long as there is enough yin soul qi, the ghost corpse can break through in an instant, unlike immortal cultivators, every breakthrough is accumulated over time, and the result of long-term cultivation, the only thing that Luo Yu needs to spend a little bit of attention on is refining the yin qi in Wang Fu's ghost banner and ghost corpse, I am afraid that with the innate true fire he currently masters, it will take a lot of time to completely refine.

After Luo Yu took care of everything, he opened all the prohibitions outside the cave, and when the entrance of the cave was covered by the light of the three basic formations, Luo Yu returned to the elixir room with confidence and began to refine the ghost flag.

With one hand, the soul refining banner floated quietly above Luo Yu's head, and after raising his eyes and glancing at the ghost flag, Luo Yu shouted lightly: "Fire Condensation Technique!", suddenly three fist-sized fireballs appeared in front of him, and the two hands were slightly closed, these three fireballs were intertwined at once, turning into a basin-sized sea of fire, these three fireballs were all innate true fires released by Luo Yu, because now his cultivation has reached the ninth layer of the Qi cultivation period, so he can release three true fires at once.

With a slight move aimed at the ghost banner above his head, the latter quickly flew to the sea of fire, and continued to rotate in the sea of fire according to Luo Yu's control.

"Hiss!" As soon as the oni banner entered the sea of fire, it released a black light mask on its own, and the sea of fire burned on the black light mask and hissed.

This is the yin qi collected in the magic weapon, as long as this black light mask is refined, the yin qi inside can be collected, and then transferred to another ghost corpse, it is considered to be done, but the process of refining the black light mask in the middle may be a little long, after all, this method is to destroy a ghost banner magic weapon.

As Luo Yu's innate true fire continued to burn, countless Yin Soul Ghost Creatures suddenly roared angrily from the ghost flags, and the sound was extremely poignant!

But Luo Yu was unmoved, just staring at the ghost flag, constantly manipulating the sea of fire to attack, as if he had expected those sharp howls.

......

Time passed slowly, and in a blink of an eye, Luo Yu had been in retreat for more than half a year this time, and Luo Yu's harvest in this half year was also great, as early as a month ago, Luo Yu had already broken through to the tenth layer of the Qi training period, because with the assistance of the medium-grade marrow cleansing pill and a large number of Jingyuan pills, this breakthrough was still in Luo Yu's expectations.

And in the past six months, in addition to retreat, Luo Yu has secretly investigated everything about Jian Chen, after all, Luo Qingqing is her sister, and she has taken care of him since he was a child, Luo Yu has become a person who cultivates immortals, and sooner or later he will cut off contact with the secular world, and then there will only be Luo Qingqing as a relative.

However, Luo Yu has not been able to find out anything in the past six months!

I don't know if Jian Chen learned from Luo Qingqing's mouth that Luo Yu had suspected him, so this person was cautious in everything he did, and he didn't show the slightest hint of carelessness!

After half a year of investigation, Luo Yu's suspicion of this person dropped a lot, and at that time, he suspected this person with only one voice, maybe he was really reckless.

As for Luo Qingqing and Luo Yu, the two sisters and brothers broke up unhappily, Luo Qingqing came to Luo Yu again within a few days, after all, the two still cared about each other very much, and they reconciled after chatting a few words, of course, both of them deliberately avoided the sensitive topic of Jian Chen, Luo Yu also felt a little guilty in his heart, but under the guidance of Luo Qingqing's lively and cheerful personality, his suspicion of Jian Chen gradually faded.

In the past six months, after Luo Yu reached the tenth layer of the Qi training period, because the mana increased a lot, the speed of refining the ghost banner was greatly improved, and it only took about two months to transfer all the yin qi in it to another ghost corpse, and then the ghost corpse completely transformed because it absorbed enough yin qi, and the process of transformation was unexpectedly fast for Luo Yu, it only took a few hours, and a ghost corpse at the peak of qi training came out...
