The secret room under the secret room of the main altar of the Kagyu sect is already the retreat of the sect leader Zuihou, he will not escape here unless he has to, he has studied this secret room for many years, he was looking for the source of mana in the underground palace to find here, the first time he entered here he was attacked by a spell wave, the powerful ice spell almost killed him, when he fled in horror and faintly heard a roar from the tunnel.

Since that time, the sect leader did not dare to open the entrance of the tunnel again for half a year, but ambition overcame fear after half a year, he opened the entrance to the tunnel again, and then used the members of the Kagyu sect to carry out treasure hunting activities, the experiment has never stopped over the years, and countless people have been sent into the tunnel by him, but not even one person can come back, and what is even more strange is that whenever the person who entered the last time dies, the entrance to the tunnel can be opened again, and those people from the last time disappear, and not a single body can be found.

What made him most frustrated was the loss of so many sect members, and the mana field of the dungeon showed no signs of weakening at all, which made him gradually lose patience and give up hope, but so many lives are not worthless, he still summed up some rules in the tunnel, one of which is that once someone enters the tunnel, the entrance of the tunnel will be sealed and closed, unless the person who enters dies or finds a way out by himself, otherwise the people outside will not be able to enter without tens of thousands of years of mana.

That is to say, now he and Niu Zhuzhu can go out with only one person at most.

This time, he really took the risk after "plotting a way", hoping to use the powerful mana field here to deal with Niu Xuanzhu, after all, he was the only one who could successfully escape from the tunnel.

Niu Xuanzhu didn't know the weirdness of this tunnel at all, and followed the sect leader into the tunnel, but as soon as he came, he felt that the aura in it was wrong, and his actions were greatly restricted. It's like suddenly carrying a big fat girl of more than 400 pounds on her back, and her speed is more than twice as slow as when she was outside.

This frightened him, and he thought that he had been hit by the sect master's slowing spell, and a shadow of death hung over his heart, and with his current speed, he couldn't catch up with the sect master's teleportation, let alone avoid the light of death. Niu Xuanzhu regretted it, but when he turned around, he found that the hole he had just entered had long since disappeared, and by this time the sect leader had already turned his head to look at him with a fierce gaze.

Niu Xuanzhu must not have imagined that the Sect Master's surprise was not much less than his, because the situation when he came in this time was completely different from the last time he came in. His only escape room experience was completely useless.

When the sect leader came in, he was ready to dodge the mana attack of the tunnel, and was ready to cooperate with the authentic Fabo to attack the Niu Zhu at any time, and took Niu Zhuzhu's life in one fell swoop, but the tunnel did not attack him at all this time, nor did he attack the Niu Zhu, which caught him a little off guard. When he tried to teleport away from the Oxbolt, he found that the teleportation spell had completely failed in the tunnel.

The Sect Master immediately realized that the effect of this tunnel was different every time he entered, and there would be a certain ability that would be limited to the maximum. And this time, he and the bull bolt column won the lottery ticket, which said "no fast movement".

The Master wants to unleash the light of death. But after making a move, I found that this super slowdown effect also had an effect on mana, and the light of death was already as slow as an ordinary mana attack.

Niu Xuanzhu was almost desperate when he saw the sect leader make a move, he just instinctively leaned back, but he didn't expect to just dodge the sect leader's attack, but because he was not used to slowing down, his body fell directly to the ground, and the back of his head was like a big fist.

"Suffer death!" The sect leader could see that the speed of the bull bolt pillar was also slow. Seeing that the bullbolt pillar fell to the ground, he hurriedly continued to attack as fast as possible to the bullbolt pillar that was rolling and climbing on the ground.

Niu Shuzhu escaped death and hurriedly used the lazy donkey rolling magic skill, but the space in the tunnel was limited, and Niu Shuzhu really couldn't roll any tricks, and he felt a sudden pain in his arm after a few rolls. A bloody wound swept out of his left arm by the light of death.

The man of the cow bolt pillar was still in the tunnel, but his soul had already scared out of the tunnel, and at this time he had been forced into a corner, and the sect leader was getting closer and closer to him.

Another light of death came, and Niu Zhuzhu sent out a law wave indiscriminately.

With a "bang", the magic wave of the bull bolt pillar magically blocked the light of death of the sect leader.

It turns out that the light of death is just a super-fast magic wave, and the laws of physics say that the faster the speed, the greater the liliang, and the magic wave of this sect leader is just an astonishing speed, but under the deceleration effect of the tunnel, his death light has been separated from invincibility and returned to its essence.

Niu Zhuzhu opened his eyes in surprise, and finally realized that it was not only his speed that had been reduced in this tunnel.

"Hey, I said sect leader, why are you doing this, what's the benefit to you of getting such a whole slowdown spell, now that the light of death can't threaten me, what else do you have to be aspirant?" Niu Shuzhu shouted at the sect leader.

"Even if that's the case, I can kill me!" The Sect Master launched an even more frantic attack on the Niu Bolt Pillar. He didn't want Niu Zhuzhu to have a chance to fight back, and he didn't want Niu Zhuzhu to see that his teleportation had also failed.

Niu Zhuzhu also put his hands together, using Fabo to attack the Sect Master, but because his Fabo speed is slower, he has been in a defensive state.

Originally, the decisive battle between the two people was a duel of speed, but I didn't expect it to become a competition of mana after entering the tunnel, which is like a light master and a hidden weapon master competing for internal strength.

Really speaking of mana, the magic that Niu Xuanzhu can use is not the opponent of the sect leader, fortunately he is the defensive side, and some attacks can also be dodged with the "fast" movement of the body, which makes his blue mana not depleted quickly, and his strength is fists, he must think of a way to fight back before the mana is exhausted.

If you want to fight back, you have to take a risk, Niu Xuanzhu gritted his teeth while defending and stood up along the wall, and then used the wall as a support to approach the sect leader little by little.

The closer he was to the Niu Zhu Pillar, the more dangerous it became, and the Sect Master slowly moved towards the Niu Zhu Pillar, and whoever of the two would die on the spot if he had the slightest slackness.

When a ray of death light struck a blood groove on Niu Zhuzhu's right leg again, the sect leader sneered in his hand, he knew that if he got a little closer, he could inflict fatal damage on Niu Zhuzhu.

And all of Niu Zhuzhu's energy was also hit by the distance between the two, and when he couldn't fully defend against the light of death, he rushed towards the sect leader with all his might, and concentrated all his mana on his fists! (To be continued......)
