During this time, humans and the Demon race had begun to wage war. And some traces of the Demon race had also appeared in the Red Rock Mountains where they were stationed. Once, while patrolling, he even saw two streaks of light, one black and one blue, flashing across the sky in the distance, obviously high-level cultivators fighting. Near Yinxia City, small-scale wars occurred once or twice every month. Each side would send out teams of thousands of people, mostly led by one or two Golden Core cultivators, fifty or sixty Foundation Establishment cultivators, and thousands of Qi Refining disciples to fight each other. Because the strength of the cultivators on the battlefield varied greatly, the battles usually lasted for a day or two. First, the two sides would set up formations and defend each other. Then came the melee, mostly Foundation Establishment cultivators leading small teams to fight each other. Finally, the Golden Core experts from both sides would come out. These wars sometimes affected the Red Rock Mountains. In the end, the two sides would break into groups of three or five, or turn into individual pursuits, hunting each other's cultivators. Just now, while patrolling, he encountered a Demon race squad, led by a burly man with early Foundation Establishment cultivation. Not to mention the casualties of Golden Core experts, in the past year, three or four hundred Foundation Establishment cultivators from both sides had died. As for the Qi Refining disciples, their numbers were huge and could not be estimated, but as the bottom-level cultivators and reserve forces, their numbers did not decrease.

Zhang Ling was not optimistic about this. Although they were stationed in the Red Rock Mountains with a defensive formation, he had heard that several places with demon-sealing stones had been attacked and destroyed by the Demon race. In the Red Rock Mountains, four or five Foundation Establishment cultivators had also died during this time, including a cultivator surnamed Yang from the Giant Demon Sect. It was said that he died in an ambush by two Foundation Establishment Demon race members. Although none of the five members of their Haoyuan Sect had died yet, everyone was on edge. And their garrison mission had only just passed two years, and they still had a long time to garrison here. Zhang Ling didn't have any good ideas. In fact, their type of garrison mission was already considered easy. The cultivators participating in the war were the most dangerous. This was not a one-on-one fight. A single mistake could lead to the fall of even a Golden Core expert, let alone Foundation Establishment cultivators like them. He was also trying to find ways to enhance his self-preservation methods. He used a recently learned sword technique when he killed the Demon race burly man not long ago. It was the 'Illusion Sword Technique' recorded on one side of the gold foil he had obtained, and the other side recorded the method of refining sword talismans. He had studied the Illusion Sword Technique when he first obtained it, and cultivators with Qi Refining cultivation could not practice it. This was a sword control technique that conjured sword shadows. Although it was not very offensive, it could conjure sword shadows, split them to attack the enemy, and play a certain deceptive role. The power of the split sword shadows varied depending on one's own strength. With his current strength, he could only split up to eight sword shadows at full strength. The attack power of each sword shadow was only equivalent to the power of a Qi Refining peak cultivator using a high-grade magic weapon. However, he was already very satisfied with this kind of power. Although the power was not great, the enemy could not ignore these attacks during battle. In short, the attack power was not great, but the harassment was extremely strong. A month ago, he also re-refined an Iron Sword Talisman, still using a five- or six-hundred-year-old ironwood as raw material. The Iron Sword Talisman had a powerful attack. When he ambushed Wei Shen, he once thought he had killed him. This kind of powerful magic weapon was enough to threaten late-stage Foundation Establishment cultivators. At the same time, the Soul Piercing Bead was also refined from the second-order demon soul exchanged at the trade fair. It used the demon soul of a second-order Azure Fire Wolf. However, some errors occurred during the refining process, causing damage to the demon soul, and the actual power in battle might be weaker. However, he was now at the Foundation Establishment stage. As long as the Soul Piercing Bead could make the opponent lose consciousness for a moment, he was confident that he could instantly solve the opponent. In addition to these two trump cards, he also had a corpse bear whose strength was equivalent to the early stage of Foundation Establishment, which was also a major killer.

At the same time, the Corrosive Spirit Water, Soul Confusion Smoke, and Blood Burning Pill obtained from the Original Poison Scripture were also refined. The actual effect of the Corrosive Spirit Water and Soul Confusion Smoke could only be seen when used in battle. He had personally swallowed one Blood Burning Pill. After taking it, the blood and energy in his body would be transformed into spiritual power, and his strength would be greatly enhanced. With his current cultivation, taking the Blood Burning Pill could make his strength directly approach the mid-stage of Foundation Establishment. But the effect would only last for a quarter of an hour. After it failed, his blood and energy would decline, his strength would drop sharply, and he would be weak for the next three or four days, and his strength could only be half of what it was. This kind of elixir could only be taken in times of crisis. If he couldn't kill the enemy in a short time, he would fall into crisis. Unless it was a matter of life and death, he would not easily take the risk. In addition to these external strengths, his cultivation was also progressing slowly, and the spiritual power in his body had increased by about 10% to 20% compared to two years ago. The Heavy Yuan Profound Light attached to the Dry Earth Skill had also greatly improved, and could cover a range of three feet under full display. As for the strange vines parasitizing in his body, because the Profound Soul Spirit Demon Technique had not been completed, its power had not increased much, but the problem of baleful aura in his body had been solved. At this moment, the vines had completely turned red and black, and during this time he had also done some research on the Human Yuan Baleful Pill refined by Wei Shen. This was a demon beast's inner core and most of his blood energy condensed. Although he didn't know if it was a real Human Yuan Baleful Pill. But it contained a lot of pure wood-attributed spiritual power, showing blue and red colors. Obviously, this was a wood-attributed demon core. Demon cores could only be condensed from the bodies of at least fifth-order demon beasts, and were the same type of thing as the inner cores of Golden Core cultivators. Its value was immeasurable, but this Human Yuan Baleful Pill that had been refined had many small cracks on it, and some vine roots were parasitized on it, which was very strange. In the past two years, he had also refined this treasure, but it had no effect. However, during a research, he found that it could actually stay in the vines. Then he found that the vines could move away from his body, and could also become giant vines, greatly increasing their attack power. He could also control the giant vines, and coupled with the strong baleful aura on them, this undoubtedly gave him another means. Compared to before, his strength could be said to have greatly increased, and he now had the power to fight against mid-stage Foundation Establishment. Just as he was thinking about these things, a furry little thing suddenly circled around his feet a few times. Meow… Meow meow! This was an orange cat about the size of an adult domestic cat, but it had two tails. The little thing jumped onto the stone table and rubbed his arm. "Tiger, are you hungry again?" Zhang Ling touched the orange cat's furry head, patted his storage bag, took out a green porcelain bottle, poured out two brown pills from it, and floated them in the air. Seeing the pills, the kitten meowed and swallowed the two pills into its mouth with a movement. Then it fell to the ground, walked to the corner by the wall, and squatted there to start its daily licking of fur. Zhang Ling's eyes flashed with a yellow light. In two years, the spiritual power of this mutated white spirit beast was also equivalent to that of a Qi Refining mid-stage cultivator. However, apart from spitting fireballs, nothing special had been found about this spirit beast. The pills he fed the orange cat were a common "Spirit Feeding Pill". This was also a pill used by most cultivators to cultivate spirit beasts. It was easy to refine. With the Spirit Feeding Pill, the orange cat could have this kind of strength in just two years. Suddenly, his divine sense moved, and he turned his head to look at the entrance of the cave. With a flash of spiritual light in his hand, a red streamer flew in.

Zhang Ling waved his hand and grabbed the red light in his hand. The light dissipated and it was a red sound transmission talisman.
