After a while, the two came to the fourth level.

"We act together. Lin Xiaohao opened his mouth and said, in this fourth level, there are two killers guarding it, and each of them is in the late stage of real strength.

"Okay, let's all act, you on the side, me on the other. Zi Qian said, she felt that this killer was extraordinary, this killer was a double sword killer, everyone had a sword in their hands, one blue and one white, exuding a terrifying aura, this was a semi-magic weapon.

"Let's go. Lin Xiaohao said, he walked in the clouds, quickly forward, and then launched an attack, the speed was extremely fast.

He flew straight forward, then condensed his fingers into a sword and slashed straight downward.

"The blue and white sword, the sword is boundless. Suddenly, the killer with the blue and white sword in his hand attacked upward, the speed was extremely fast, only to see two blue and white rays flashing by, and then Lin Xiaohao, Zi Qian hit directly, with an incomparably powerful momentum, as if it would destroy everything.

"The bloody knife is without a trace. Zi Qian's body surged, swung her sword, and struck straight forward, this speed was beyond imagination, only to see a blood light fly straight up, and then attack downward, slashing downward, as if to destroy everything.

"Boom!" In an instant, a huge deafening roar rang out, and the surrounding rocks suddenly fell straight down, as if making people feel the boundless terrifying aura, the rock powder flew all over the place, and the entire cave seemed to be destroyed.

"Blue Breath, you are left and I am right!" said the killer holding the white sword to the killer holding the blue sword, and the aura on his body surged up, making people feel all kinds of terrifying aura, and the white sword qi was vertical and horizontal.

"White light, I know. The blue breath killer said, he waved the blue sword in his hand, really ran hard, and then a sword flew straight out, and hit Zi Qian on the left, this sword seemed to be with crystal blue, as if it would perish everything, and fluttered backwards in a flash, the breath made people feel as if waving all kinds of extraordinary things, making people feel all kinds of terrifying breath, his sword fluttered, as if a sword shadow fluttered out of it, it seemed to destroy everything, in fact, it was so strong, it had reached the late stage of true strength, and people felt the terrible breath in it, as if it would destroy people。

And the white light struck straight at Lin Xiaohao.

"Blue is invincible, white is everything. In an instant, Bai Guang and Lan Xi shouted at the same time, the aura on their bodies suddenly increased, the true strength surged, the two combined, and the aura was so powerful that it reached a terrifying level, reaching the late stage of true strength.

The two of them jointly attacked Lin Xiaohao and Zi Qian, and the two of them waved the swords in their hands, as if countless Dao swords were flying out of them, making people feel that thousands of Dao swords were flying, and they felt that the entire cave was full of swords.

"Condense your fingers into a sword, break!" Lin Xiaohao's aura was running, and he swung a sword forward, only to see the golden sword light flying straight up, and the blue and white rays flying around him were cut by him, and the sword shadow was also cut by him, feeling like a boundless extraordinary aura, and feeling all kinds of terrifying rays.

"The intent of the sword to extinguish!" At this time, Zi Qian also activated the true strength of her body, and flew straight forward, the blood knife flew straight up, surging in the air, as if it was flying boundlessly, and then a blood light flashed by, cutting off all the sword rays around her.

"Blue and white sword, one sword is extinguished!" In an instant, the breath of blue breath and white light surged up, they held the blue and white sword in their hands, the sword movement was boundless, and the true strength flew straight forward, the strength of that breath was their strongest, this was an incomparably powerful attack, it was their strongest attack.

"Blood knife, give it to me!" Zi Qian's eyes were red, and the light on her body flew straight up, and blood marks appeared, making people feel as if there was a blood knife appearing, flying in this cave, and then countless blood knives converged and condensed into a huge blood knife.

Zi Qian waved the blood knife in her hand, and the huge blood knife in the cave slowly lifted upward, and then Zi Qian swung straight down, and in an instant, a huge blood knife slashed straight down.

"Boom!" It seemed that the boundless huge sword was emerging, and then attacked forward, this aura was so strong that it was beyond imagination, and then a knife swung through, and with the sound of the boom, all the blue and white swords around it were wiped out, and there was nothing left.

"Click!" only to hear the sound of a knife shattering, and in an instant, the two blue and white swords were instantly cut off, turned into pieces, and dissipated.

Lan Xi, Bai Guang looked at the broken sword in his hand, his eyes were shocked and frightened, he didn't expect such a strong attack to appear, and this powerful pseudo-magic weapon was all destroyed.

"Extinguish!" Zi Qian said, she gently spit out a word, and suddenly, the blood knife flew straight up, hitting the neck of Blue Breath and White Light, only to see two blood splashes, Blue Breath, and White Light suddenly fell to the ground, motionless, and lifeless.

In the next moment, the blood knife returned to Zi Qian's hand, and the blood in the blood knife slowly dripped down, exuding a cold aura.

"The fifth level, let's go!" Zi Qian said, her voice cold, as if it came from a thousand-year-old ice cave.

Lin Xiaohao sighed lightly, and then the two of them walked towards the fifth level.

This fifth level looks very simple, there is only a middle-aged man there, and he is holding a flute in his hand, which looks very ordinary.

But Lin Xiaohao knows that this fifth level is not simple at all, this is a terrifying level, this is the strongest level among the five elements level, this middle-aged man exudes a strong true energy aura, giving people a sense of strength, and the aura on his body seems to destroy everything.

"Welcome to the fifth level, my name is Wei Guan, here, no one can pass through, you are the first to come here, no one has ever come to this Tongtangkou before, you are the first to arrive, it seems that someone has leaked the information of Tongtangkou, but these are not important, the important thing is that you will be wiped out, or you will be enslaved by the people in Tongtangkou, and you will not have anything left. Wei Guan looked at Lin Xiaohao, and Zi Qian said, the aura on her body was extremely strong.

"Oh, is it?" Lin Xiaohao said lightly, his breath calm.

"Hmph, Tongtangkou, in my opinion, it's just that, I will destroy all the people here, I will avenge the people in the orphanage who were killed by you back then, and you will all be wiped out. ”

Zi Qian said, the aura on her body was cold, and the blood knife seemed to gradually flash with the terrifying glow of the Dao, and the aura of destruction surged in the flash.

"The Bronze Hall will definitely be destroyed, you will not be the last, and your hall master will not be the last. ”

Zi Qian said, she looked at Wei Guan coldly. “
