Fang Yun rushed forward while observing the battle situation. He had already judged in his heart that the monsters and barbarians had basically unified.
Before this, the monsters would occasionally launch sneak attacks, but they were never on such a large scale. The main reason was that no single tribe could mobilize such a large team, and since they were not united, it was naturally impossible for them to join forces wholeheartedly.
Now, Yaoman can actually mobilize two teams of the same size at the same time and send out a force equivalent to 30% of the top leaders. Except for the order from the Wolf King, no other force can do it.
Fang Yun realized that he would not be able to complete the test without dealing with the demon king.
Fang Yun discovered that these monsters did not attack with all their strength. A few great monster kings seemed to have grudges against some great scholars and were constantly insulting them, but the two sides were too far away and the specific sounds could not be heard.
Some of the monsters secretly observed the direction of Shu City and Chuan City from time to time, apparently hoping that humans would come to rescue them so that they could surround and attack the reinforcements.
Fang Yun looked towards Sichuan City, where there was war raging. Endless flames cut through the night sky, and powerful forces were shaking in the north of the city.
Fang Yun walked forward while thinking about the battle plan. Those monsters below the fourth realm were no more than chickens and dogs, but the great monster kings of the fourth and fifth realms were not easy to kill.
The reason why the four realms could be quickly dealt with before was because the opponents gathered together and relied on the power of the collision between the Family, Country and the World and the Divine Strike. Otherwise, although the True Dragon Ancient Sword is powerful, it will still take a long time to kill so many great demon kings of the four realms.
Fang Yun's eyes fell on the mechanical fortress that was about to be destroyed. The mechanical fortress was the crystallization of the engineering technology, so naturally all aspects were taken into consideration, and the final destruction of both sides was the ultimate means of the engineering fortress.
Fang Yun touched the brocade bag containing the Gongjia Fortress on his body and slowed down slightly.
When they were about a hundred miles away from the battlefield, the monsters discovered Fang Yun.
"That's a great scholar from the fourth realm. Send two from the fourth realm and six great demon kings to surround and kill him quickly, and then come back quickly!" A wolf demon king ordered.
The eight great demon kings laughed wildly and glared at Fang Yun with red eyes, like wild beasts encountering delicious food.
The attacks on the human race in the mechanical fortress were reduced, but they were not happy. Instead, they looked at Fang Yun anxiously.
Emperor Wenzong Liu Lieyang sent a slightly angry message to Fang Yun: "You are of noble status, how can you go into danger! Get away from here immediately. If you die here, we are all sinners, and the entire industry is a sinner of the human race!"
Liu Lieyang knew too well the value of Fang Yun. Fang Yun's death here was basically equivalent to the death of a semi-saint of the human race.
Fang Yun sent a message: "We encountered a sneak attack team of similar size, but I and others have already dealt with it. I asked them to go to Chongcheng, and I will rescue you myself. These monsters are nothing to be afraid of."
Liu Lieyang was stunned for a moment, and immediately judged that Fang Yun's strength was far beyond his previous expectations. He was very clear about the strength of the other great scholars and university scholars. To put it bluntly, let alone a similar scale, even if the besieging monsters were only one-third of them, it would be difficult for them to win.
Fang Yun continued to transmit his voice: "Although they pose no threat, if they escape and join forces with the Wolf King, it will be a big trouble. Therefore, we have to sacrifice some organs or forces to keep them all here."
"You say, and I will do it!" Liu Lieyang's eyes flashed with desire for victory.
After Fang Yun gave his orders quickly, the eight great demon kings had already arrived.
Fang Yun's aura suddenly changed, and he said in a loud and dignified voice: "Wherever my body is, wherever righteousness is. My blood will turn into jade, and I will exchange my thirty years of life for the righteousness of heaven and earth!" After saying that, Fang Yun slapped his chest with his right hand and suddenly spat out a little blood, which fell on the True Dragon Ancient Sword.
Fang Yun did not tell Liu Lieyang in advance that he was going to use Blood and Heart. When Liu Lieyang and others saw this scene, they were excited and their eyes were moist. A virtual saint of the human race could have not cared about people in the literary world, but now he gave up his life to save them. This kind of spirit can only be possessed by the great sages of ancient times. The realm of such people is already comparable to that of the saints. They are truly the most benevolent, righteous, kind and virtuous.
The great demon kings were also stunned for a moment, and looked at Fang Yun with a little more respect in their eyes. However, a great scholar of the fourth realm was besieged by eight great demon kings, and he would definitely die even if he had great abilities, so they did not care too much, but just remembered the appearance of this brave human.
In fact, Fang Yun did not use the Blood and Heart at all. The blood was forced out. He did this to create an illusion. After killing the eight-headed demon king, he would let everyone think that he relied on the power of the Blood and Heart to prevent the demons from discovering his true strength and running away. After all, this time was different from the previous situation.
Great scholars are able to inspire great righteousness, so people cannot tell whether their loyalty is genuine or not.
Afterwards, the True Dragon Ancient Sword, carrying with it a powerful force, first quickly killed six ordinary great demon kings, and then killed two fourth-level great demon kings at a slower speed.
Seeing that all eight great demon kings were killed, the remaining great demon kings were furious. Not only did they not doubt Fang Yun's strength, but they looked down on Fang Yun even more because his lifespan was shortened by thirty years, and they all asked for a fight.
The leading wolf demon king didn't think much about it and sent out eight demon kings of the same size to kill Fang Yun.
So Fang Yun patted his chest again and shouted loudly: "Wherever my body is, my righteousness will be. My blood will turn into jade and I will exchange my fifty years of life for the righteousness of heaven and earth!"
Afterwards, Fang Yun controlled his energy to slightly whiten his hair and increase the wrinkles on his body, making him look decades older.
The pressure on the humans who were fighting was reduced again. They looked at Fang Yun who used Blood and Heart again, tears welled up in their eyes, and they wished they could sacrifice their lives in place of Fang Yun.
Hearing that Fang Yun had sacrificed fifty years of his life, the great demon kings felt more at ease. The great scholars in the four realms were basically over fifty years old. After sacrificing eighty years of their life in a row, they would surely die.
The wolf demon king who was in the lead gave the order: "You eight don't need to take any risks. Begin by slowly surrounding him and wait until his Blood and Heart lasts for a while before you attack with all your strength."
The eight great demon kings stopped five miles away from Fang Yun with a smile on their faces and attacked Fang Yun with long-range magic.
However, Fang Yun attacked desperately as if he was crazy.
Then, within a dozen breaths, the big demon kings who were besieging the mechanical fortress suddenly discovered that the second batch of eight big demon kings who went to intercept Fang Yun had all died.
In terms of numbers alone, it is equivalent to the loss of nearly one-third of the troops.
They had some doubts at first, but when they noticed that Fang Yun's hair had turned completely white, his skin was wrinkled and loose, his body was shaking slightly, he was breathing heavily, sweating profusely, and his progress was very slow, they dispelled their doubts.
The wolf leader did not underestimate the enemy and said, "Wolf Tooth King, you lead the four great demon kings to kill him. Go quickly and come back quickly!"
"Haha, Wolf King, you refused my request for a fight just now, so now you have to rely on me!" The Wolf Tooth King of the fifth realm roared at Fang Yun and rushed towards Fang Yun with four great demon kings of the fourth realm.
Fang Yun's face was filled with grief and indignation. With endless sorrow, he shouted for the third time: "Wherever my body is, my righteousness will remain. My blood will turn into jade and I will exchange a hundred years of life for the righteousness of heaven and earth!"
Afterwards, Fang Yun's aura surged, but his body looked older.
