The sound transmission notes and the message transmission talisman were not things that were found earlier, but rather the newly invented product after Ge Xuan talked to Huo Hai several times. After being inspired by him, this thing not only requires spiritual talismans, but also the special spiritual treasures he refined to be assisted to be used successfully. At present, only Yu Ji, who participated in the development, has a finished product in his hand.

Therefore, even though Huo Hai had read Taiping Qingling and Taiping's Techniques, he did not know the existence of these new things, and he did not know that some of his thoughts and thoughts allowed Ge Xuan's practice to embark on another path.

Moreover, due to insufficient practice of Taoism, he could not use these things at all.

I saw Yu Ji took out a conch-shaped thing from his cloth bag, lit a piece of talisman paper that had been drawn long ago, stuffed it into the big screw mouth, and silently recited the three words "let him go". The conch-shaped spiritual treasure immediately made a buzzing sound, as if it was transmitting some sound waves in a direction.

Soon, Zuo Ci, Ge Xuan and Sun Jian, who were in the battle, all their bodies were paused, slowing down the pace of the attack.

Wu Kui, who felt relaxed, began to observe the surrounding environment and looked up at the sky.

"It's a pity to let him go like this." After Yu Ji took over the spiritual treasure, he narrowed his eyes and looked at Wu Kui who was looking for an opportunity to escape.

Since he was planning to escape, it proved that his backup plan was almost used. As long as he was willing to fight for his life, he should be able to stay.

"Killing him is just a matter of time. If the price is too high, it will not be worth it." Huo Hai comforted Yu Ji.

Judging from his tone, it seems that he has already had some good solution.

"Okay! I just hope that during the period when you find a solution, he will not commit too much murder." Yu Ji finally sighed.

When he was using the sound transmission note just now, Wu Kui should have heard some movement. This is where the sound transmission note is not quite complete. He cannot transmit sound one-to-one like making a phone call.

Sure enough, after the dark clouds covered the moon, Wu Kui made a big move. He kept shaking his huge body, and his whole body slowly turned into a ball of black smoke and disappeared into the dark night where he could not see his fingers. Suddenly, the entire area was in a very dark silence, which made Zuo Ci, Ge Xuan and Sun Jian have to stop and dare not act rashly.

"Strengthen your vigilance, don't be careless." After Huo Hai issued an order to the Heishan Army, he soon heard a series of screams from the Han army camp.

"No, that guy actually took the opportunity to sneak into the Han army camp. If he was asked to kill too many people, we might not be able to control the spread of the Gu insects." Yu Ji reacted immediately.

Upon hearing this, Zuo Ci, Ge Xuan, and Sun Jian all began to rush towards the Han army camp, and Huo Hai also regretted it.

This music transmission note actually ruined the matter, allowing Wu Kui to find a breakthrough in turning the tables.

However, when Zuo Ci, Ge Xuan and Sun Jian entered the Han army camp, there was no large-scale fight there.

"That guy ran away, but it left us with a big trouble. The insects in the Han army camp may not be able to control them. We must prepare to fight." After the dispersing skills, Zuo Ci, who was somewhat weak, rushed over and said, then sat cross-legged, began to close his eyes and breathe and adjust his breathing.

Hearing this, Huo Hai immediately ordered, "Quickly, free up all the box trucks in the camp, each eight people, each group of two Han soldiers came out of the camp, let them be controlled in one car and wait for treatment."

He had previously considered how to deal with the emergency in case the Han army camp collapsed. Unexpectedly, these methods would be used so soon.

However, the Black Mountain Army had only more than 2,000 box trucks. Even if one car could be used as an isolation place for two people, it could only treat more than 4,000 people at most, which is less than one-quarter of the total number of Han Army camps.

"General Sun, you still need to personally supervise and maintain the order of the Han army. At present, I can only save more than 4,000 people. If you don't save whoever you save, you and General Zhu will choose for yourself!" After Huo Hai issued the order, he rushed towards Sun Jian, who was about to ask Huo Hai for advice.

"Is there no better way to do this?" Sun Jian said in a dilemma.

"It's just that you discovered it too late. Even if you saved more than 4,000 people, I took great risks." Huo Hai said helplessly.

During the conversation between the two, Yu Ji had already started to get busy again. At present, the only way to save more people is to prepare a feed that the worms cannot resist, use Huo Hai's insect fishing method to quickly fish out the worms in the Han army, and attract which adults are killed to prevent them from spreading randomly.

"You guys, let's help together!" Ge Xuan looked at Cui Xuan and other monks who had just dealt with his injuries and watched in front of the formation.

With the help of those who are knowledgeable, Yu Ji's preparation speed has accelerated a lot, while Ge Xuan took out a bone flute from his cloth bag and began to play it at the Gu insects in the spittoon.

"Is this?" Huo Hai looked at Ge Xuan with some confusion and asked.

"I want to try whether using different sound waves can work on these insects." Ge Xuan answered Huo Hai and continued to start the experiment.

Huo Hai knew that Wu Kui's method of controlling the insects was just sound, smell, food, etc., so he no longer disturbed his experiments, but followed Sun Jian's back and went to the door of the Han army camp.

Soon, he saw several Han generals running out of the camp with Zhu Yan.

"What's going on?" Huo Hai asked the Han generals through the isolation ditch.

"Many brothers in the camp have become corpse soldiers who kill everyone they see. General Zhu refused to evacuate, so we knocked it out and sent it out." A Han general with an internal strength level at least in the middle stage answered Huo Haidao.

"I can accept you here, but you must cooperate with our treatment plan after you come here. Moreover, if the situation in the Han army camp is bad, you must obey what I do if I deal with them." Huo Hai said ugly words before.

"Listen to him."

While several Han military lieutenants were still hesitating, Sun Jian, who came over with a group of people, spoke directly.

The people behind him were not only Cheng Pu and Huang Gai, but also the local heroes he recruited from his hometown. Obviously, the first thing he had to ensure the safety of his subordinates.

"Don't worry, those who are coming here should first cover their mouth and nose with a facial towel, and come in two or two. Before entering the isolation area, your saliva can only be swallowed into your stomach and you cannot spit out anything." Huo Hai said.

Soon, some facial scarves were thrown by his soldiers, and then, the bridge made of two horizontal ladders was shelved in the isolation pit, and a Han army captain carried Zhu Jun and walked towards this side with the ladder bridge.

With Zhu Jun in hand, the battle with the Han army was stable. I used his hand to contact Yecheng, Handan City, and the Han army camp, and they should be able to get a lot of medical resources.

Soon, more Han troops gathered in front of the camp gate, and the screams and fighting sounds in the camp became higher and higher. Huo Hai knew that there should be a purgatory in the Han army camp. After seeing some soldiers rushing towards the isolation ditch from other directions, he decisively ordered the firewood in the isolation ditch to light up, and let the infantry line up to prepare fire attack equipment.

Sun Jian, who came directly over the pit, looked at Huo Haidao with some pain in his eyes, "You really want to burn everyone in the camp to ashes?"

"Do you have a better way?" Huo Hai asked Sun Jian.

Upon hearing this, Sun Jian was silent, but he didn't expect that good news came from Yu Ji at this time.

"No need for fire attack, I have prepared a feed that is very tempting to the worms. I just need to disperse its smell and put it into the Han army camp, so that the worms in the camp can swarm and no longer attack other hosts."

"But even so, we can't make much feed, and we can't save so many people." Huo Hai asked.

"Although I have not found a way to control the worms with sound waves, I have figured out how to use sound waves to make them restless. I just need to enter the camp and play the bone flute at close range to make the worms in the bodies of the Han soldiers restless, which can play a certain vomiting effect. At least it can prevent the worms from continuing to eat the food in the soldiers' belly and delay the time of their physical failure. When the spitted worms are tempted by the smell of this feed, they will concentrate in the same place, which gives us the opportunity to kill the adults quickly." Ge Xuan rushed over and spoke at this time.

"In this way, you will take action." Huo Hai felt that the solution was very feasible.

"When you go to the Han army camp, be careful of Wu Kui, he may not have gone far." Yu Ji reminded Ge Xuan.

Ge Xuan nodded, picked up the things handed over by Cui Xuan and others, flew over the isolation ditch, and entered the Han army camp.

Huo Hai looked at his back and turned to ask Yu Ji, "What kind of interests do you think can make this guy Wu Kui fight us to the death?"

Yu Ji thought about it and replied, "Maybe it's the survival problem of his tribe members!"

Huo Hai raised his eyebrows and said, "The major barbarians in the south are not unable to survive!"

Yu Ji shook his head and said, "If it weren't for Wu Kui and other barbarian monks, the Southern Barbarians would have been wiped out long ago during the reign of Emperor Wu. The reason why he spared no effort to gain resources for his tribe is because there were few rising stars in recent generations of the Southern Barbarians. If he was gone, the court would send a few troops to wipe out the Southern Barbarian tribes."

Huo Hai frowned and said, "You said, if we can join forces with the Southern Barbarians, will Wu Kui turn to us?"

"You dare to accept such a cruel and bloodthirsty person?" Yu Ji looked at Huo Haidao in surprise.
