On the other side, after Lin Xun left Xiao An Village, he was not in a hurry to attack Ping An County.
Instead, he rushed all the way to the Gray Cloud Ridge.
In this place, he still had a large amount of resources-the bones of the Japanese!
Bones were precious treasures to some cultivators who cultivated the Skeleton Devil Dao.
Although Lin Xun didn't cultivate the Skeleton Fiend Path, he couldn't waste such a large amount of resources, right?
Moreover, even if he didn't cultivate the Skeleton Fiend Dao, his bones could be used to refine some magic treasures.
For example, after the Yin Soul Banner in his hand was refined to the hundred soul level, the materials he used previously could no longer keep up with the strength of the Yin souls contained in it.
He had to refine it with some other materials to continue becoming stronger.
The Spiritual Bone Marrow, a substance extracted from bones, was the best strengthening material.
Last time, he didn't have the method to extract the Spiritual Bone Marrow, so he could only store the bones in the Japanese's camp. This time, before coming to Canglan Jie, he went to the Mission Hall to exchange for the method to extract the Spiritual Bone Marrow. At the same time, he was prepared to refine the Yin Soul Banner again here.
Soon, Lin Xun landed on a small hill made of bones.
"I didn't expect this Li Yun Long to be so kind. He actually helped me collect these skeletons together, saving me a lot of effort!”
Lin Xun nodded in satisfaction when he saw the mountain of bones.
The Japanese had left over 3,000 skeletons on the battlefield of the Gray Cloud Ridge. It would take a lot of time for Lin Xun to collect them one by one.
Since Li Yun Long could get people to gather them, Lin Xun was naturally happy.
"Yin Soul Banner, rise!"
Lin Xun flew up from the small mountain of bones and took out the Yin Soul Banner in the air. In an instant, a gust of cold wind blew in the Ghost's camp, and hundreds of Yin Souls instantly occupied the entire void.
"Soul Flame, ignite!"
Lin Xun formed a hand seal, and the hundreds of Yin souls immediately spat out a pale blue flame from their mouths.
This flame was called Soul Fire!
It is a kind of flame naturally condensed by Ghost Dao cultivators. Although its temperature is not high, it has a miraculous effect when used to extract Bone Spirit Marrow.
Hundreds of light blue flames landed on the small mountain of bones, and the ghost's bones immediately burned fiercely.
Lin Xun controlled the fire while continuously sprinkling spell seals and white powder into the small mountain of bones.
After a while, the small mountain of bones shrank at a speed visible to the naked eye and collapsed.
In the end, only a washbasin-sized ball of white liquid was left in the air.
This was the Spiritual Bone Marrow!
In Canglan Jie, this thing was sold by the drop!
One drop was worth 3 contribution points or a low-grade spirit stone.
There were at least a thousand drops of this Bone Spirit Marrow, which was equivalent to a thousand low-grade spirit stones.
Such a large amount of wealth made even Lin Xun, who was currently quite wealthy, envious.
"In addition to the 300 drops that I refined after killing the Japanese special forces, it should be enough to refine the Yin Soul Banner to a higher level!”
Looking at the ball of liquid floating in the air, Lin Xun nodded in satisfaction.
When he first started to refine the Yin Soul Banner, the materials he exchanged were all street goods. The Yin Soul Banner he refined did not have much growth.
After raising all the Yin souls to the sixth level of Qi Refinement, they fell into a bottleneck.
The strength of the dark spirit was limited by the grade of the banner itself.
When Lin Xun killed the Japanese's special forces in the Tiger Leaping Gorge and collected the souls, a small crack appeared on the surface of the Yin Soul Banner.
The Zhe Representative meant that the power that the Yin Soul Banner could withstand had reached its limit.
But now that he had these Spiritual Bone Marrow, Lin Xun was confident that he could refine the Yin Soul Banner even more firmly. By then, the strength of the hundreds of Yin Souls would be further improved.
After recalling the refinement method of the Yin Soul Banner in his mind, Lin Xun suddenly spat out a mouthful of demonic flames and enveloped the Yin Soul Banner.
"Bone Spiritual Marrow, go!"
Lin Xun pointed his finger, and the white liquid floating in the air poured down like mercury, landing on the surface of the Yin Soul Banner.
When the black banner came into contact with the white Bone Marrow, a wonderful chemical reaction immediately occurred and it began to devour the Bone Marrow crazily.
Seeing this, Lin Xun's hands frantically formed seals, and streams of pure demonic qi began to flow into the banner.
At the same time, he kept taking out some materials from his storage bag and melted the Yin souls into liquid with his soul fire before throwing them into the Yin Soul Banner.
These materials were the spoils of war he had obtained after killing the Lin brothers, and he could use them now.
Three hours later, the pitch-black Yin Soul Banner began to emit a jade-like luster.
"Sacrifice!"
Lin Xun cast the last spell, and with a flash of lightning, the brand new Yin Soul Banner was finally refined.
Looking at the brand new Yin Soul Banner, Lin Xun nodded in satisfaction.
The current Yin Soul Banner was enough to accommodate more Yin souls. It could also automatically absorb the spiritual qi of heaven and earth to slowly nurture the souls within.
In other words, even if Lin Xun didn't continue to throw in other souls, the Yin souls inside could still slowly increase their strength.
Of course, this was not the most important thing!
With the Japanese in the World of the Unsheathed Sword as his resources, Lin Xun had no lack of souls.
However, the number of souls that the Yin Soul Banner could hold was limited. He was a little reluctant to kill the ghosts wantonly. After all, the souls in this world were too fragile. If he did not collect them in time, they would easily dissipate.
But now that the Yin Soul Banner could accommodate a large number of souls, Lin Xun could naturally kill the ghosts without any scruples.
"With the current strength of the Ghost Banner, it should be enough to accommodate the 30,000 ghosts in Pingan County!”
Lin Xun revealed his signature cold smile again.
Every time he revealed this smile, it meant that someone was going to be unlucky!
