"A guest elder!" Hearing this, Zhang Ling no longer had any doubts. He had naturally heard of guest elders. Usually, only rogue cultivators would take on such roles, serving as elders from outside the family for some clans. Cultivation families would also use the reputation of these cultivators to enhance their strength. Even some rogue cultivators in the Golden Core stage would serve as guest elders for some cultivation families and small sects. "This treasure is so precious that I naturally cannot accept it easily. As for serving as a guest elder for your family, Senior Brother, it's not too late to discuss this matter if I can return safely." Zhang Ling thought for a moment and said, patting the storage bag at his waist, a wooden box flew out. "This is a rare spiritual herb. How about Senior Brother take a look?" Wu Minghan frowned upon hearing this, but he subconsciously caught the box as it flew over. Then, he opened the box and saw a small, blue-green grass lying inside. As soon as he saw this spiritual herb, a look of great joy appeared on Wu Minghan's face. "This is a second-order spiritual herb, Azure Lotus Grass. The medicinal fragrance is rich. Growing this big, it must be at least three hundred years old." "Haha, that's right. This is a five-hundred-year-old Azure Lotus Grass, which I obtained by chance."

Zhang Ling replied with a laugh. Seeing Wu Minghan's expression, he knew that this Skythunder Seed belonged to him. Azure Lotus Grass is the main ingredient for refining Azure Blue Pills, a rare spiritual herb of the second order. Azure Blue Pills are a precious elixir for cultivators who practice wood attribute techniques. It can quickly increase a cultivator's cultivation. Wu Minghan happened to be practicing wood attribute techniques, so he naturally couldn't refuse this item. This spiritual herb was also specially nurtured by him, precisely to cope with insufficient spirit stones and some special situations. Now, exchanging it for the Skythunder Seed was just right. He expected that Wu Minghan would not refuse. The Azure Lotus Grass was already five hundred years old. The Azure Blue Pills refined from it would be enough for him to cultivate for a year or two. The longer the age, the stronger the medicinal power. If refined into Azure Blue Pills, this person's cultivation could be several times faster. It could shorten four or five years of cultivation progress. Although the Skythunder Seed was precious, it was still somewhat inferior compared to the enhancement of cultivation. Actually, he could have obtained this Skythunder Seed even without taking out this spiritual herb, but he didn't want to become a guest elder. Although guest elders generally don't have many responsibilities, if he agreed to this matter, it would be difficult to refuse if this person asked him to do something later. It would be best if he could exchange this treasure with a spiritual herb. Wu Minghan's expression changed, as if he was considering the pros and cons. "Zhang Junior Brother is truly blessed to obtain this precious spiritual herb. I happen to need this spiritual herb. As for the matter of the guest elder, it's not too late to discuss it in detail when Junior Brother returns." "It's just good luck. Isn't my luck at its worst now? The upcoming reinforcement operation is a matter of life and death. With the Skythunder Seed being so powerful, I naturally won't forget Senior Brother's kindness in gifting me this treasure." After the two exchanged a few more words, Wu Minghan bid farewell and left. Zhang Ling looked at the Skythunder Seed in his hand and happily put it into his storage bag. With a wave of his hand, the flying boat was released by him. He controlled the magical artifact and flew towards the south side of Redrock Town. Before long, he arrived at a stone archway at the foot of a mountain. Almost all of the Foundation Establishment cultivators had arrived. After waiting for a while, all fifteen cultivators had arrived. Suddenly, the sky darkened, and a black-red cloud appeared and floated above their heads. "Are you all not coming up yet? You are too slow. I will take you there." Zhang Ling and the others quickly flew into the cloud. The cloud was dark and gloomy. Uncle-Master Han was standing inside with his hands behind his back. After everyone entered the red cloud, the red cloud trembled and quickly flew towards the sky. Zhang Ling and the others only felt that the black-red cloud under their feet was unusually thick and solid, and they could also hear bursts of whistling wind in their ears. Obviously, they were flying at high speed.

... Half an hour later, they arrived at Azure Moon Lake, located on the south side of Redrock Mountain. The red cloud dissipated, and the group landed in front of a small valley. This place was a mess. Many trees around were collapsed and broken, and some places in the distance were still emitting a series of flames. Rumble! A fierce battle was taking place on the side of the sky. In the sky, a cloud of green smoke covering a hundred zhang range was floating, condensed and not scattered, and groups of green gas flew out of it, a spectacle of horror. The target of these green shadows was a rapidly moving figure, and for a while, it was not clear whether the person was male or female. Only to see more than ten blue long swords surrounded the figure. These flying swords were very flexible, flying around the figure quickly, and the green light groups that attacked were all beheaded and destroyed one by one. "The protective array here has been broken, but the Demon Sealing Stone will not be easily destroyed. You go there to support." Uncle-Master Han, in front of the crowd, looked at the fight in the distance, and a cold light flashed in his eyes. He said to the crowd. Then, flames emerged from his body and covered him in it, and then rushed towards the direction of the fight in the sky. Only to see that Uncle-Master Han turned into a flash of fire and reached more than ten zhang in mid-air, and then the fire dimmed and disappeared. I don't know what secret method was used to hide the figure. "Everyone, let's go to support quickly." I don't know who said a sentence, and everyone rushed to the other side quickly. There was also a burst of huge noise, and obviously there were other monks fighting. Zhang Ling and two fellow disciples looked at each other and also walked with wind under their feet, closely following the large army. Before long, everyone came to the center of the valley, where there was a large pool, and at the moment, the center of the pool was surrounded by clouds and fog, forming a cloud of white fog, covering a region. There were also twenty or so alien demons attacking the white fog with various magical instruments. Seeing this, these supporting monks did not say a word, and took the magic weapons and went to the alien demons to kill. At this point, Zhang Ling frowned and glanced at the distant sky, where it was still the same as before, only two senior monks were fighting. It's just that the information they got said that there were two Golden Core monks attacking Qingyue Lake, how come only one was seen. I was puzzled, but since I have arrived here, there is naturally no room for retreat. Following the monks to the battle group, he first sacrificed the Flying Spirit Shield, and then took out a spirit talisman and patted it on his body, forming a blue defensive shield. Finally, he threw out the flying sword and surrounded him. In a blink of an eye, their fifteen people and twenty-odd alien demons fought into a ball. At the same time, the white fog in the center of the pool rolled, and seven or eight Foundation Establishment monks rushed out of it and joined the ranks of encircling and suppressing alien demons. Zhang Ling swept around with his divine sense, but did not find Mu Xiaoyan. I don't know if there was an accident or if he had escaped from this place. He only had time to roughly observe the battlefield, and a bald alien demon appeared in front of him. This person was wielding a gray strange blade that looked like a knife and a sword, and rushed towards him with a roar. Zhang Ling's eyes narrowed and he didn't think much about it. The flying sword in front of him turned into a streamer and greeted him.

Next to him, Hao Ming, this senior brother of the Haoyuan Sect, shouted loudly, and a fire flashed on his body, and two inch-long flying knives attacked an alien demon. Next to him, Tian Jing, a golden light flashed on her body, and a golden short sword floated on the top of her head. Under her magic formula, the golden sword rotated rapidly to form a golden sword wheel, shooting out golden sword shadows one after another. This woman is practicing a rare gold attribute technique. Among the five elements of spiritual roots, there are very few outstanding gold spiritual roots, and the gold attribute is also the most difficult to practice among the five elements of magic. Among the five elements of exercises, the gold attribute has the strongest attack power, followed by the fire attribute. In a blink of an eye, the battlefield formed several large and small battle groups. Some people, like the three of them, attacked the enemy back to back. This can prevent some people from attacking. There are also monks who deal with the enemy alone. For a while, it is not clear which side has the upper hand. ...
