"I'm going back to the underworld to report on my work, thanks to you for this time, otherwise I wouldn't have been able to kill the Hercules Ghost King at all. ”

After Hei Wuchang finished speaking, he bent his fingers, and a cloud of black aura shot towards Ling Feng's eyebrows.

Ling Feng didn't resist either, fused this group of divine thoughts, and immediately obtained a mental method, but it was a complete version of the Impermanence Soul Locking Sutra, completing the missing part of qi training, including condensing the Xuanyin Golden Pill, the Yuan Shen Law Body, etc., which could be cultivated to the peak of the Wuzun realm. And there is also the impermanence change secret technique that Ling Feng wants most. This secret technique is based on the Impermanence Soul Locking Sutra, and it is not difficult for Ling Feng to refine it, and it can also be added through the essence value. If he refines to impermanence, his camouflage ability will be greatly improved, and he can save his life at a critical time, or even turn the tables.

"Thank you!"

Ling Feng hugged his fists, he was still a little troubled by the impermanence order damage, but after obtaining this exercise, his heart was balanced.

At this time, Hei Wuchang said: "You're welcome, this is what I should do, in addition, you take out the body of the Mighty Ghost King, and I will refine it for you into the Jingyuan Relic, as for those ghost generals and ghost pawns, let them go to the underworld with me." ”

"Then thank you Brother Impermanence!"

Ling Feng said with a smile, his Divine Soul cultivation at this time had already entered the early stage of the Sixth Order, and then he had refined some of the Ghost King Yuan Shen, and his cultivation had expanded greatly, so it was time to consolidate his cultivation. Besides, without the soul chain, it took too much time for him to refine the evil ghosts, and the gains outweighed the losses. Similarly, it was too time-consuming for him to refine the body of the Mighty Ghost King, and he could save a lot of time by having Black Impermanence do it for him.

Subsequently, under the refining of black impermanence, the thick essence hidden in the body of the Mighty Ghost King was refined and condensed into a black essence relic, and the amount of essence contained was almost equivalent to a golden pill at the peak of the Martial King. However, the cultivation of the underworld is the way of Xuanyin, and these essence elements are all pure yin attributes, which conflict with the qi and blood essence elements of pure yang attributes, and cannot be directly used to transform into true dragon essences, but can only be used to improve the chaos true elements.

Immediately, Black Impermanence picked up the discarded Impermanence Order and the Iron Mixing Rod from the corpse of the Black Rock Ghost who was smashed into meat cakes, among which the Impermanence Order was his token, and handed the Iron Rod to Ling Feng, saying, "Brother Lin, I'm leaving, the gap between the two worlds here is very useful to you, and it can help you understand the laws of the underworld." You can practice here for a while first. However, at most a year, I will return to the prefecture and report the situation here to the prefecture's higher-ups. At that time, the underworld will send an envoy to take over the place, and if you are interested, you can try to make friends with the underworld envoy and get cooperation. ”

Ling Feng nodded, hugged his fists and said, "Thank you, Brother Impermanence, I'll send you away." ”

Hei Wuchang nodded, and the Yuanshen Law Domain unfolded, enveloping all the ghost armies and entering them into his Yuanshen space, and then the three of them crossed the Ghost King Hall and the Black Water Military Camp all the way to the northernmost Netherworld Passage.

The entrance of the Netherworld Passage is a huge space-time vortex, which is the node where the Netherworld meets, and the rich Netherworld Qi flows from the channel into the Yin side of Shaoyin Mountain. This Netherworld Qi is the Underworld Aura, and its quality is much purer than that of ordinary Xuanyin Qi.

This is also the reason why the Xuanyin Qi here is extremely strong. It can be compared to the passage here, but it is not worth mentioning, if you cultivate here, one day is comparable to several months, it is like having a mysterious-level peak spiritual vein that will never be exhausted, making people spit out and cultivate.

And this passage is not passable at all times, there are often spatial cracks, and occasionally there are space storms, once encountered, it is likely to be doomed. Nether passages are most stable only around July of each year.

Of course, the danger also depends on who it is, for ordinary ghost generals, it is naturally very dangerous to return to the underworld at this time, but for a ghost king powerhouse like Hei Wuchang, as long as he is not unlucky enough to encounter a space storm, there will basically be no danger.

Ling Feng looked at the back of Hei Wuchang in the distance, his mood was a little complicated, and then he took the Heavenly Wolf Knife and the pass token from Concubine You, and said, "You went to search the Ghost King Palace, and found the benefits, you two and I eight." ”

“......”

Concubine You was so angry that she wanted to scold her mother, it was too dark, but she then seemed to remember something, so she smiled and rushed away.

At this time, Ling Feng took the Blood Sea Pearl, began to refine the blood element, restore the true dragon essence, and run the blood veins around his body. He continuously activated the Immortal True Body and the Chaos True Dragon bloodline, although it was not for a long time, but he also fell into a weak state, and through the circulation of the True Dragon Essence Element, he was able to speed up the elimination of the weak state.

At the same time, the Chaos Vortex in his body was also constantly absorbing Netherworld Qi and restoring the Chaos True Element.

Half an hour later, Ling Feng opened his eyes, and at this time, the True Dragon Essence Yuan had almost recovered, so he put away the Blood Sea Pearls and began to count the harvest.

Killing ordinary demons only has chivalrous value and soul fragments, and no essence value drops, and only the underworld life races such as the Hercules Ghost King and the Black Rock Ghost Shuai drop essence points.

Ling Feng killed the Mighty Ghost King and the Four Great Ghost Shuai, and obtained a spirit value of 6 million, a chivalrous value of 7.68 million, three Xuanyin Yuan God fragments, and 8 Yang God fragments, and the richness of the drop far exceeded his estimate. Among them, the drop of essence value is mainly the contribution of the strong ghost king, this guy is in the middle of the ghost king, and he directly dropped 5.12 million essence value. And the main gain is the chivalrous value, which can already be exchanged for two sixth-order magic weapons.

Devouring souls is the heaviest evil karma, and the Mighty Ghost King, as a ghost king, and the four major ghost commanders under his command, they have killed and devoured countless ghost cultivators, and naturally the sin value is deep, so the chivalrous value will be so rich.

In addition, a total of sixth-order high-grade divine weapons demon dragon sticks, four fifth-order divine weapons, three fifth-order battle armors, and one Jingyuan relic were obtained, which can be described as a bumper harvest. There are also many other hidden benefits, such as refining the Ghost King Yuanshen, having a certain understanding of the Yuanshen Realm in advance, the quality of the Chaos Spirit Bead has been slightly improved, and he has also obtained the right to use this gap between the two realms for nearly a year.

Immediately, Ling Feng remembered what Black Impermanence said, which was beneficial to comprehending the Netherworld Law, so he took out the True Dragon Sword and inserted it beside him to warn, and began to sit with his eyes closed, his soul mind sensed the underworld channel, and by comparing it with Shaoyin Mountain Yin, he suddenly sensed obvious fluctuations in the Netherworld Law. If it is in the underworld, although the laws of the underworld can be seen everywhere, it is also like seeing flowers in the fog, and it is difficult to understand. But this is the intersection of the two worlds, half of which is the law of the human world and half of the law of the netherworld, and this comparison can realize the subtleties of the two laws.

"I see, no wonder the Netherworld Palace Master's law comprehension is so deep, and the Netherworld Palace must also have an underworld passage. ”

Ling Feng suddenly said, and immediately rejoiced, with this underworld passage, whether it is the cultivation speed or the power of comprehending the laws of the netherworld, he can get twice the result with half the effort and improve by leaps and bounds. Immediately, he gathered his thoughts and concentrated on comprehending the Netherworld's Laws.
