As a teacher of the Martial Academy, Tang Zi'an naturally knew everything about the academy's mountain guarding array, so as early as when Mu Bei released thousands of Gu worms with the Yin and Yang reversal technique, he had already discovered that something was wrong.

This aberrations come from two sides, but in reality, they are the same thing.

The first is that there is a problem with the mountain defense array.

Secondly, it was accompanied by the excitement of the Gu worms, and there was a burst of awe-inspiring aura!

The former is because of Ying Tianwu.

The latter is because of Xia Sheng.

Or more accurately, from that ghostly black spring.

Xia Sheng once sank the Evil Banner into it, originally it was just for the purpose of surveillance, but by chance, the evil qi in the Ghost Spring was much stronger than before, if it weren't for the clear spring in the mountain behind the academy to restrain each other, I'm afraid that at this time, the entire Buju Mountain has become a Jedi with no grass!

Before leaving the prison in the belly of the mountain, Xia Sheng knew that the ghostly black spring would inevitably destroy the entire stone cave with a monstrous aura.

At that time, Xia Sheng didn't feel that there was anything wrong with this matter.

Because that prison is a nightmare that Ying Tianwu will not get rid of, and if it is destroyed, it will be destroyed.

But now, Tang Zi'an was rushing towards the belly of the mountain, so things suddenly became complicated.

The power of the Ghost Black Spring Xia Sheng is very clear, especially after the Evil Banner sinks to the bottom of the spring, the evil qi in it has condensed to a very terrifying level, it is no exaggeration to say that even if Tang Zi'an is the Venerable of the Sword, he will definitely not be able to resist it!

knew that Tang Zi'an was going to be more auspicious. Xia Sheng didn't care about anything else, and immediately chased Tang Zi'an's pace and caught up.

However. Although Xia Sheng fused with the Emperor River, and the four wings behind him shook rapidly, how could he keep up with the speed of a sword venerable?

By the time he returned to the darkness in the middle of the mountain, it was already late.

Tang Zi'an raised his sword with one hand, and stood in front of the ghostly black spring with a solemn expression, his sword intent was surging all over his body, but his face became more and more pale.

As early as when Tang Zi'an fought with Mu Bei. He was injured a little, and later in the front hall of the academy, Tang Zi'an single-handedly stopped nearly seventy percent of the Gu worms. In the end, together with Xia Sheng, he forcibly stimulated the Qingying Sword Formation, so to speak, at this time. It is at the weakest time of my life.

At this time, he was alone in the face of the mysterious black spring. Even though there were thousands of sword qi to protect his body, it was still gradually eroded in his heart, and a dark cyan ink line stretched up on Tang Zi'an's chest, passed through his neck, and came to his face, immediately reflecting his face as purple and black as a demon.

This is the manifestation of evil qi invading the body!

Seeing this, Xia Sheng's heart sank violently and wanted to rush forward. helped Tang Zi'an, but was stopped by a blue light curtain at the entrance of the cave.

"What are you doing! Get out of here!"

Facing Tang Zi'an's hard drink. Xia Sheng's heart had sunk to the bottom, and he said urgently: "Let me in, I can help you suppress the evil spirit here!"

Tang Zi'an smiled faintly and muttered, "It's too late." ”

As Tang Zi'an's words fell, a roar immediately sounded in the stone cave, and then looked at Tang Zi'an, his left arm had turned into a white bone.

Flesh and blood are destroyed.

Seeing this, Xia Sheng's eyes were slightly red, and he immediately invited out the Haoran Sword in the sea of qi and slashed towards the azure light curtain.

"Bell!"

The strong force collision directly shook Xia Sheng back three feet, however, even with the Haoran Sword, Xia Sheng still couldn't break Tang Zi'an's light curtain in the slightest!

Seeing this, Xia Sheng's face was so heavy that he could drip water, and he said sharply: "Tang Zi'an, open the enchantment for me!"

Tang Zi'an turned a deaf ear to Xia Sheng's anger, but looked at the Haoran Sword in Xia Sheng's hand, and showed a pleased smile: "Last time when I was on the Life and Death Stage, I guessed that you had obtained the entire inheritance of Emperor Gaozong, and now it seems that your kid is hiding very deeply, and he even got the Haoran Sword." ”

After that, another popping sound sounded in front of Tang Zi'an, and his left leg was gone.

So in the next moment, Tang Zi'an stumbled and fell to the ground completely, but his hand holding the sword was still as steady as Mount Tai.

His voice began to become a little ethereal: "There is a barbarian master infiltrated in the academy, whether you can find him out depends on your ability, and when the dean comes back, remember to tell him that I finally lived up to his expectations......

"By the way, there is also Jiang Qiqi, she is my closed disciple, and I will have to rely on you to take care of her in the future. ”

Xia Sheng's eyes were cracking, and he couldn't help but roar angrily: "Tang Zi'an! If you have anything to say, you go and tell the dean yourself, if there is anyone to take care of, you take care of it yourself, I don't have so much spare time! Now you hurry up and open this qi wall for me!"

Tang Zi'an did not respond to Xia Sheng's words, perhaps because he couldn't hear any sound at this time, and he still had a breath, but he didn't want to swallow it.

In the end, he looked at Xia Sheng extremely calmly, showed a relieved smile, and said: "I know that you are not an ordinary person, even the academy cannot accommodate your ambitions, but I hope that you will never betray the academy, whether you agree or not, I will hand over the future of the academy to you." ”

After saying this, Tang Zi'an didn't want anything more, let out a soft roar from his mouth, drew an incomparably perfect arc in his right hand, and gently fell into the ghost black spring.

This is Tang Zi'an's last sword, and it is also his most powerful sword, because at this time he has fused with the long sword, and there is no separation between each other.

Turning into a sword, but begging to slash all the evil spirits here!

The next moment, in this dark cave, a long sword with a length of five zhang and a width of five zhang appeared, and it burst out with an almost golden destructive brilliance, slashing towards the pool of eternal black ink-like spring.

Frightened by it, the evil qi storm in the field began to frantically erode towards the sword body, but in the blink of an eye, it corroded gaps the size of rice grains on the long sword.

However, Tang Zi'an's sword is too powerful, representing his lifelong cultivation, as well as all his perceptions of swordsmanship, as well as the brilliance of life.

So immediately afterwards, the entire stone cave began to collapse violently, and the evil aura was cut off by Tang Zi'an with a sword, and then the rusty long sword fell above the mouth of the ghost spring, sealing the breath inside, and then buried in it by the boulder, never to be seen again.

Xia Sheng watched this scene, his face was already extremely distorted, but he couldn't do anything.

Then, a mournful cry resounded through the sky at the entrance of the cave.

"Dean Tang!"
