After the national teacher slapped his chest, Xu Qing already knew the intention of the national teacher.

The heart and blood is the foundation of the blood of the cultivator, containing the natal vitality of the cultivator, the average person only has three hearts and minds, even if they lose a mouthful of blood, they will also be greatly injured, and they have to cultivate for a long time.

But it is also because the heart and blood contain the natal vitality of the cultivator, if the magic weapon is fed with the heart and blood, the power of the magic weapon will be doubled, and many cultivators are forced to helpless, but still endure the pain of using the heart and blood to increase the power of the magic weapon, although it is not appropriate to have a serious injury to the vitality, but it is better than losing one's life.

Although the treasure of blood refining is not a magic weapon, it is almost the same as a magic weapon, and even because of its characteristics, it is more bloodthirsty than a magic weapon, absorbing the hard work of the national teacher, and its power can be imagined, and the power will definitely be doubled.

Xu Qing was worried that he would not have time to hide in the jade tower, so he took out a jade talisman from the storage bag, which was the defensive jade talisman left by the ancestors, and he grabbed it in the palm of his hand and was ready to crush it at any time. Although he was very reluctant in his heart, after all, the preciousness of the jade talisman could be imagined, but now that the situation was critical, he couldn't take care of it so much.

With the light drink of the national teacher, the blood-colored flying sword devoured Xu Qing like a bloodthirsty poisonous snake, and after the blood-colored flying sword, there was a blood-colored, like a sea of blood upside down, and the waves were monstrous, and he wanted to drown Xu Qing in it.

After absorbing a mouthful of blood, the blood-colored flying sword obviously doubled in power, and its speed also doubled, faster than lightning, if it came through space, Xu Qing had no time to dodge at all, he could only choose to resist.

But looking at its might, Xu Qing was really not sure that the bronze mirror would be able to withstand this blow, and even if it could, its anti-shock power was not something that Xu Qing could afford.

Just as Xu Qing was about to crush the jade talisman, Xu Qing vaguely felt a breeze blowing, and his body was indescribably comfortable, but he was also slightly distracted for a moment, and when he reacted, the blood-colored flying sword had already hit the light curtain with boundless might, Xu Qing regretted that he had made such a mistake at the critical time of the war, it really shouldn't be.

It's just that regret is useless at this moment, Xu Qing can only hope that the bronze mirror that Uncle Shi praised will not be destroyed, and let the blood-colored flying sword directly hit his body, otherwise the consequences will be known without thinking about it, there is no suspense.

Xu Qing wanted to retreat quickly, wanting to take advantage of this to ease the power of the impact a little, and then crush the jade talisman, but Xu Qing quickly noticed that something was wrong, he didn't feel the impact of the blood-colored flying sword at all, the power was incomparable, the indomitable blood sword was like a breeze, the sea of blood was reversed, and the terrifying waves were already calm.

Could it be that the national teacher was just bluffing? But he had obviously spewed out a mouthful of blood, how could it be a bluff? Xu Qing couldn't help but secretly say, he really couldn't understand that this change was too sudden, and even a little weird.

The national teacher was originally looking at Xu Qing with a cruel smile, he wanted to see Xu Qing being torn apart with his own eyes, and a bright red appeared on his pale face, which was caused by the extreme excitement.

It's just that the next moment, the hideous smile quickly froze, and his pupils were full of disbelief, and the blow he threw all his strength into was easily resisted by Xu Qing, as if he hadn't tried his best yet, and he still had some strength left.

"Impossible! Kill me! Kill! Kill!"

The national teacher shouted frantically, his eyes were bloodshot, his face was hideous, and he looked like crazy, directing the blood-colored flying sword to attack Xu Qing, without any rules at all.

Every time the blood-colored flying sword is mighty, as if the sky is dyed with blood, the red light floods half of the sky, but the ending seems to be doomed, the light curtain of the bronze mirror always easily resists the blood-colored flying sword, to put it mildly, the bronze mirror does not move like a mountain, and the blood-colored flying sword is unmatched, and its light curtain cannot make the slightest tremble.

The blood-colored flying sword slammed several times in succession, each time it was in vain, regardless of its power, just looking at its might, you could also feel that the momentum of the blood sword was constantly weakening, obviously that the blood was almost exhausted.

What's even more hateful is that Xu Qing is like an outsider, standing with his hands in his hands, as if he is not in the battle situation, everything has nothing to do with him, how indifferent.

The national teacher was already completely crazy, and he would never stop if he didn't kill Xu Qing, his right palm slapped on his chest without hesitation, and a mouthful of blood spurted out, and the blood-colored flying sword quickly devoured the blood without any drops left.

After a mouthful of blood spurted out, the national teacher's face was as pale as paper, even if he could kill Xu Qing today, he would definitely be greatly injured, without ten years of recuperation, coupled with the help of countless elixirs to restore vitality, it would be difficult to recover to his peak state, and even if he was not careful, he would never survive in his life.

It's just that the national teacher didn't stop there, his right palm slapped on his chest again, and another mouthful of blood spurted out of his mouth, and the amount of this heart's blood was much larger than the previous one, equivalent to a mouthful and a half of heart's blood, and the blood-colored flying sword was excited again to completely devour the heart's blood.

The last breath of hard work seems to have pulled all the vitality out of the national teacher, although the hair is still black, but has lost all its luster. His face was not old, but it gave the impression of an old man in the twilight of his life, as if a gust of wind could blow him down.

Obviously, he has gone completely crazy, otherwise he would definitely not do this, even if he kills Xu Qing today, he definitely has no possibility of survival, it can be said that he will definitely die.

Xu Qing saw that he squirted out two more mouthfuls of blood, and was slightly moved.

After the blood-colored flying sword devoured the two mouthfuls of blood, it burst out with a red light that soared into the sky, and the red light covered the sky and the sun, like the appearance of the sea of blood in Shura, and the smell of blood in the air was disgusting.

The blood sword hovered around the master's body, constantly emitting a clanging sword sound, as if it felt the death of the master and screamed for it. Then he suddenly felt the determination of his master, like a poisonous snake spitting out a letter, staring at Xu Qing in the distance.

Then the blood-colored flying sword drew a beautiful line and slashed towards Xu Qing, like a scythe of death, indifferent and ruthless, but mixed with bloodthirsty emotions, so contradictory, and so harmonious.

After absorbing two mouthfuls of blood, the power of the blood-colored flying sword increased again, its momentum was unstoppable, its speed was invisible, like blood-colored lightning piercing the sky, all obstacles would be shattered and completely annihilated.

This time, the blood-colored flying sword did not stab directly at the light curtain, but slashed horizontally, as if it wanted to cut Xu Qing in the waist to vent the hatred in his heart. It's just that when the blood-colored lightning approached Xu Qing, it was like a mud cow entering the sea, and the monstrous blood waves quickly calmed down without the slightest wave.

The blood-colored flying sword was surrounded by boundless blood, but every time it approached Xu Qing, the blood color would be stripped off a layer, and the speed would be slower by one point, and when the blood-colored flying sword really approached the light curtain in front of Xu Qing, its speed was almost undetectable, and the blood color on it was completely peeled off, and finally fell directly at Xu Qingdi's feet, wailing on the ground.

The national teacher has been watching, watching quietly, this time he didn't have any special reaction, even if the blood-colored flying sword fell to the ground and screamed, he was indifferent, his eyes were still flat, but if he looked closely, he would definitely find that his eyes were empty and lackluster.
