Putting away the corpse, Qin Sang took out the mustard seed bag of the three people.

The harvest is not bad, there are more than seven hundred lower-grade spirit stones in the three mustard seed bags, and there are also a few good magic weapons, especially in the mustard seed bag of the black-robed old man, there are two top-grade magic weapons.

One of them was a black long sword, the old man in the black robe used this sword to fight hard before he died, it was extremely powerful, and the quality was definitely stronger than the Yanli sword.

Qin Sang erased the old man's divine sense, waved his hand a few times, and took advantage of it, so he kept it for his own use, replacing the sword with Yanli.

The other is a piece of light yarn, called the Heavenly Poison Yarn, once urged, the light yarn will turn into a cloud of Yin Poison Miasma, which can be regarded as an enhanced version of the Yin Poison Miasma of the other two.

This miasma is highly poisonous, once an immortal cultivator is hit, the spiritual power in his body is stagnant, and if he can't detoxify it in time, he will end up with mermaid flesh.

The black-robed old man fell into Qin Sang's trap first and landed in the Ten Directions Yama Array, so he didn't have a chance to exert the power of the Heavenly Poison Veil, so he was killed by Qin Sang.

Qin Sang was discovered by his opponent during a fishing operation, and his opponent discovered the existence of Purple Soul Ling, and he was not aware of it for a while, causing Purple Soul Ling to be hit by sword qi and damaged, and the Heavenly Poison Yarn was not as secretive and direct as Purple Soul Ling, but it was still too powerful.

The Heavenly Poison Veil floated in the void, sometimes turning into a poisonous miasma, sometimes returning to its original appearance, Qin Sang took it for his own use after some sacrifices, and suddenly his heart moved, and he took out the cloud of Yin Poison Miasma that he had put away before and threw it into the air.

Then he saw that the Heavenly Poison Veil suddenly opened, and without Qin Sang's order, he couldn't wait to swallow the Yin Poison Miasma in one gulp. This yin poisonous miasma was indeed separated from the heavenly poison veil, and after the two were combined, the power increased by two percent.

Qin Sang nodded secretly, these two magic weapons can only be regarded as slightly inferior in the category of the best magic weapons, but an ordinary monk whose cultivation is similar to that of the old man in the black robe, it is not bad to have one, it can be seen that this kind of trade is indeed unprofitable.

However, in the end, these three people still could not escape the fate of dying for money. Even Qin Sang had encountered strong enemies many times when fishing, and he did not capsize with the powerful magic weapons of the ebony sword.

In addition to these, it was some consumables that were necessary in the Gu Immortal Battlefield, such as the elixir and the cloud weapon, which were all things that Qin Sang needed, and after sorting them out, they were all put away, and then the mustard seed bags of the three of them were destroyed.

The cave is secluded.

Qin Sang sat cross-legged with his eyes closed, and there were bursts of spiritual power fluctuations on his body, and the spiritual energy in the cave seemed to encounter a great suction, and it was being continuously absorbed and exhaled by Qin Sang.

At this time, Qin Sang was concentrating on cultivation.

In the Yuan Shen, on the emerald green sword body, there is a killing talisman shining with a faint light, and next to this killing talisman, there is a half-engraved killing talisman, this half-killing talisman is also like Qin Sang's sea of qi, the glimmer forms a small whirlpool, helping him absorb the aura of heaven and earth in the cave.

Under the guidance of the exercises, these spiritual qi entered the Yuanshen space through the ebony sword, and then flowed into the meridians, and after following the exercises for a few weeks, the impurities were quenched out, completely turning into Qin Sang's own spiritual power, and finally merging into the sea of qi, making Qin Sang's cultivation speed a few points faster out of thin air.

This is the strength of the "Yuan Shen Raising Sword Chapter", the ebony sword is equivalent to Qin Sang's second dantian. Due to the limitations of talent, Qin Sang's original cultivation speed was far inferior to others, but with the help of the killing talisman, the gap could be narrowed.

Now the number of kill charms is still small, and this improvement is not obvious. As his cultivation progressed, the number of killing talismans increased, and Qin Sang's cultivation speed would also increase, eventually reaching a level comparable to that of the True Spirit Root.

As for the terrifying cultivation speed of the Heavenly Spirit Root, Qin Sang didn't dare to hope for it, if the Yuan Shen Raising Sword Chapter was not incomplete, maybe it was really possible.

After cultivating for a while, Qin Sang stopped his exercises, pinned all his mind on the ebony sword, observed the broken killing talisman for a long time, and then tried his best to carve a new stroke on it.

"Whew!"

Finally completed this stroke, Qin Sang was sweating profusely, opened his eyes, and breathed a long sigh of relief. His face was full of exhaustion, and it was obvious that completing this stroke would be a great drain on Qin Sang's mind and spiritual power.

But his eyes were full of excitement, because he felt that the inscription was easier than before, but it was only limited by cultivation, which was why it was so difficult.

After twenty years of penance, he never stopped fighting with the cloud beasts, and every time he fought, his mind was immersed in the killing talisman, contemplating the mystery of the killing talisman. Until now, he has comprehended more than eighty percent of the second killing talisman, and after a period of time, he can fully comprehend the killing talisman, cultivate hard in the cave, improve his cultivation, and then engrave the killing talisman one by one.

At that time, as long as the amount of spiritual power in the body reaches the requirements for breakthrough, it is enough to support the complete inscription of the second killing talisman on the ebony sword, and it is a matter of course to enter the middle of the foundation building period.

Now there is only one half-kill talisman on the ebony sword, and the cultivation speed is not fast enough, and this process may last for a long time.

But compared to other monks who were trapped in the bottleneck, Qin Sang preferred the current one, at least every progress was clearly visible, and there was no need to worry about not being able to make an inch for more than ten years or even decades.

That feeling, Qin Sang had learned during the Qi refining period, and it could really drive people crazy.

After that, Qin Sang stayed in the cave mansion for half a year to do penance, and then set off again and left the Heavenly Crystal Secret Realm.

He already knew the distribution of cloud beasts near the Heavenly Crystal Secret Realm, and knew how to hunt enough cloud beasts while trying to ensure his own safety.

According to the familiar route, after walking around, more than half a month had passed, and Qin Sang came to the mountain where there was a vein of Huoyuan Stone.

More than half a year has passed, and there must have been a batch of Huoyuan stones accumulated in the cave, and Qin Sang is like cutting leeks, harvesting one stubble after another, which is really a very stable source of wealth.

It took a few days to trap and kill the cloud beast entrenched above the entrance of the cave, Qin Sang urged the cloud weapon to protect the body, and then quietly infiltrated the cave.

This time the fire element stone was mined, the interval was a little long, and there were already some cloud beasts in the veins that had completely transformed, and it took Qin Sang two days to clean up the cave, and the mustard seed bag was full of harvest, and when he returned to the entrance of the cave, his complexion suddenly changed.

The sky outside is dark, the cloud beasts are roaring, the sand is flying, and the celestial phenomena are coming!

The sky was black and oppressive, covering the sky and the sun, not dark clouds, but cloud beasts that were more and more active by the celestial phenomena, and flew out from the depths of the mountain range. Looking at this scene, the celestial sign was likely to start yesterday, and he had been cleaning up the cloud beasts in the depths of the cave, but he didn't notice it.

You must not stay here, otherwise the celestial phenomena will hit and it will be a dead end!

Qin Sang's face was slightly gloomy, and he immediately took out a copper bell-shaped cloud device and put it on the top of his head, and rushed down the mountain with his head buried in it. But the distance was too close, and the cloud weapon could not completely cover Qin Sang's breath, and immediately a cloud beast discovered Qin Sang's traces!
