Zhang Haoyu looked at his body inwardly and found that the backlash of using the Heaven Slashing Sword Technique was even more serious than he imagined, most of the meridians on his body were damaged, and at the same time, all the spiritual energy in the acupoints of his body was consumed.

"This time I really got rid of it, fortunately, I forcibly suppressed the injury at that time, and I didn't show any flaws, otherwise if those demons knew that I was seriously injured at the time, they would all rush up, in that case, I don't know if I can get out of the demon cave alive!" Zhang Haoyu muttered in his heart, the situation at that time was really difficult, although he killed the demon king, but there were at least dozens of old demons around, and in that case, as long as Zhang Haoyu showed a little injured, those old demons would definitely not let him get out of the demon cave alive.

"Just let you go for some time, and the day I get healed from my injuries will be when I completely destroy this demon cave!" Zhang Haoyu made up his mind in his heart, and then began to pay attention to repairing his injuries.

Time always flows quickly inadvertently, and by the time Zhang Haoyu woke up again, it was already night.

"Whew!"

Exhaling a deep breath of turbidity, Zhang Haoyu slowly opened his eyes, looked around, and found that Zhang Wanting's sister and brother were already asleep, and there was still some food on the ground, which seemed to be left by the sister and brother to Zhang Haoyu.

Zhang Haoyu walked to Zhang Shengtian's side lightly and slowly put his hand down on Zhang Shengtian's forehead.

"Sure enough, this kid is the same as I thought, although the talent for cultivating immortals is extremely strong, and he can be regarded as a genius, but the qualifications for practicing martial arts are simply poor, not even one-third of Xiao Shizhuo!" Zhang Haoyu sighed, at first he thought that Zhang Shengtian not only had good qualifications for cultivating immortals, but even his qualifications for practicing martial arts were superior, but the fact is that God has opened a door for you, then there must be a flash of the window that is closed, and it is impossible to have both fish and bear paws.

"Find a way to let this sister and brother enter the Heavenly Sword Sect, I don't think the master should oppose me, there just happened to be this kid, Xiao Shizhuo can also be regarded as having a playmate!" Zhang Haoyu has already decided that when he finishes dealing with the affairs of the Dongzhou Demon Cave, he will take the sister and brother to the Heavenly Sword Sect, so that he can be regarded as repaying the kindness of the sister and brother for saving his life.

Zhang Haoyu took out a paper and pen from the space and wrote on it, "I'm going outside for some business, I'll be back soon!", and after putting down a conspicuous position, he flew towards the demon cave.

Although his injuries have not fully recovered, he doesn't pay much attention to a few old demons, this time he is absolutely quick to cut through the mess, and he will solve all the old demons in the demon cave at one time as soon as possible!

......

In the demon cave, it is still dark, and the light outside does not shine into the territory of this demon clan at all.

Zhang Haoyu held the Xuanyuan Sword in his hand, and the sword intent was released without any hiding, and he directly broke into the demon cave with an extremely high-profile posture.

"Hmph! this time, I'm going to destroy you all!" Zhang Haoyu made up his mind that this demon cave would completely disappear from the Shenwu Continent tonight.

The old demon in the demon cave saw that it was Zhang Haoyu who broke in, and he looked like he was going to kill the demon, and for a while he found a place to hide, and some people even wanted to do more, taking advantage of Zhang Haoyu's lack of scruples for a while, and then sneaked out while he was in chaos.

"Sword God!"

At the only exit of the Demon Cave, Zhang Haoyu directly used the sword god at the exit of the Demon Cave, and a sword slashed out a sword mark hundreds of meters long, and the sword mark was accompanied by Zhang Haoyu's own sword intent.

"All the people inside, no, all the demons inside have listened, today is the day of your demise, you can come out one by one, or a group of people deal with it together, see if you can run out of me!" Zhang Haoyu used his aura to spread this sentence to every corner of the demon cave.

As soon as he finished speaking, there were a few little demons who wanted to sneak out quietly when Zhang Haoyu couldn't pay attention to him, but as soon as they walked to the sword mark, they were wiped out by the sword intent attached to it.

"Terran, you don't have to get an inch, our demon has a contract with your Terran, it's not that you want to break the contract between the two races!" An old demon appeared tremblingly, and said tremblingly, extremely scared in his heart, for fear that Zhang Haoyu, the evil star, would kill directly!

"Contract, what contract, contract between the two clans not to go to war?" Zhang Haoyu sneered and said, the demon's approach has angered Zhang Haoyu, these demons dare to put their hands on him, then Zhang Haoyu will completely destroy this demon cave in Dongzhou no matter whether there is a contract or not!

"That's right, the contract between the two clans was signed by the strongest of the two clans, so it won't be today, if you want to break this contract, you can't do it!" The old demon had a little confidence, he felt that Zhang Haoyu would never dare to violate this contract.

"Hmph!" Zhang Haoyu snorted coldly, and then said: "Okay, if there is a contract, there will be a contract, but ......"

"But what?" the old demon asked curiously.

"But you still have to die!" Zhang Haoyu said fiercely, and then with a sword aura, he directly killed this old demon who stood up and spoke.

"I'll tell you a truth today, the strong people in this world have the final say, and now I am stronger than you, so even if there is any trouble in the future, it will be a matter of the future, but today I will ask you to die once!" As soon as the words fell, Zhang Haoyu instantly used ten thousand sword tricks, tens of thousands of sword qi, and directly swept through the entire demon cave, at this time, the entire demon cave screamed again and again, and the demon with low cultivation died instantly as soon as he touched the sword qi, and those with a little cultivation were also barely avoiding Zhang Haoyu's attack.

"Hmph! I said today that I would let you perish, and I, Zhang Haoyu, will do what I say!" While speaking, Zhang Haoyu kept communicating with Xuanyuan Sword.

Old man, help me, you are a humane artifact, born to restrain evil spirits, if I can add your blessings, then it will be much easier for me to deal with them!

Zhang Haoyu communicated with the sword spirit of Xuanyuan Sword in his heart, hoping that the sword spirit could help him once.

"Buzz!".

There was a crisp sword sound from Xuanyuan Sword's body, and then it broke away from Zhang Haoyu's hand, and the sword body slowly floated to the sky, and then the sword body began to shine with golden light, and the light became more and more powerful, and it didn't take long for the entire demon cave to be illuminated by the light of Xuanyuan Sword.

All the demons who were illuminated by the light of the Xuanyuan Sword were in pain for a while, and the supreme artifact of humanity was born with the power of restraint against all kinds of demons, so all the demons in the demon cave were in unbearable pain for a while!
