Yang Tianjun, who had just appeared, blew out a punch, which beat back the iron slaying dragon.

Yang Hongwu looked at Yang Tianjun. He was not only happy, but also blamed. The reason for his joy was that Yang Tianjun had completely refined the seal of the city master of Tieshan City, and his cultivation had broken through. Now he has reached the point of dominating. Yang Hongwu didn't expect it. He thought it would be good if Yang Tianjun could recover his cultivation, But unexpectedly, he broke through to the point of dominance.

However, this breakthrough is too fast, and it is not a good thing. The foundation is unstable, which is harmful to future cultivation, and it is easy to cause heart demons.

Under such circumstances, ordinary people can suppress their accomplishments and prevent their accomplishments from breaking through too quickly. In that case, they can make their foundation more stable and vigorous, and will not cause any hidden dangers to their future cultivation.

"Father!"

"Why are you here?" Yang Hongwu said. "It's very dangerous here, you know? You've just recovered. Moreover, your cultivation is improving too fast and your state is unstable. It's not good for your cultivation in the future."

"Father, don't worry. I know that. At present, our biggest threat is to kill the dragon with iron, isn't it? Our father and son will practice first and kill the old guy." Yang Tianjun stared at the dragon with iron and said, "that dragon axe is very important to me. If I can get the Dragon axe, I can give full play to the three Kaitian moves."

When Yang Hongwu heard the speech, he didn't expect that his son had an eye on the Dragon axe. I'm afraid the main skill he practiced was the skill of the Pangu family that panni gave him. The skill of the Pangu family is still very powerful. Yang Hongwu has to admit this.

The power of Pangu's Kaitian skill can be imagined if it is practiced to the extreme. At the beginning, Pangu's strength was not very strong, but he was able to open up the vast world. It can be seen how powerful the Pangu family's skill is?

If he thinks so, it's normal for him to stare at the Dragon axe.

It is precisely because he wants to get the Dragon killing axe that he is so radical. He directly improves his cultivation to the master level. In addition, he has refined the city master's seal and can mobilize the power of Tieshan city. Therefore, he is strong enough to be comparable to the middle of the master, so he is qualified to participate in this battle.

If he did not reach the dominant level, even if he could mobilize the strength of Tieshan City, he could not participate in such a battle. After all, his strength is too weak.

"Well, in that case, today our father and son will fight side by side, kill the old thing and help you capture the Dragon axe." Yang Hongwu knew that even if he didn't agree, he would not retreat.

With Yang Hongwu's permission, Yang Tianjun was very happy.

"Don't worry, father, I won't hold you back." Yang Tianjun said.

"Damn it, it's you who refined the seal of the leader of Tieshan city. You have the smell of chaotic star flowers on your body. Damn you." tietulong was very angry. Unexpectedly, tietulong knew that Yang Tianjun had created a chaotic star body. Tiemang grabbed Yang Tianjun, deprived each other's blood power, and made him a waste body. Moreover, he was not a chaotic star body, It can be seen that he used the star body of chaotic star flower for a long time. The original star flower was not completely mature. It took a huge price to ripen it. I'm afraid it used the resources of Tieshan city. It was his accumulation for many years, which made him angry.

"Iron dragon slaying, if you hand over your dragon slaying axe and kneel down to beg for mercy, I can spare you from death if you recognize me as the Lord." as soon as Yang Tianjun opened his mouth, he let the iron dragon slaying explode completely. He was only a master. He broke through with the origin of iron mountain city. He dared to be so arrogant and asked him to be a slave. Hateful, hateful.

"You're looking for death." the cold light in the iron Dragon Slayer's eyes flickered, and the terrible killing machine broke out in an instant. Then, he rushed towards Yang Tianjun. The Dragon Slayer's axe was held high, and the domineering momentum exploded in an instant, enveloping Yang Hongwu and Yang Tianjun. However, the target of the Dragon Slayer's axe was Yang Tianjun. Just now, Yang Tianjun made up his mind, We must kill Yang Tianjun first.

Moreover, although Yang Tianjun's cultivation level is higher than Yang Hongwu's, which is the initial stage of domination and supported by the power of Tieshan City, in fact, his combat effectiveness is weaker than Yang Hongwu's. In addition, he has just made a breakthrough, his cultivation has not been stabilized, and he has not really adapted to the power of domination, so he can't give full play to his most powerful combat effectiveness, Once fighting, there must be great flaws.

"Be careful." Yang Hongwu didn't hesitate to see that the iron dragon slaying axe locked Yang Tianjun. The immortal seal was sacrificed and bombarded the Dragon slaying axe. If it was a complete immortal seal, it would definitely be stronger than the Dragon slaying axe. However, now the immortal seal is incomplete, which is equivalent to the Dragon slaying axe.

"Hum!" Yang Tianjun gave a cold hum and offered his weapon. It was also an axe. It was also a treasure, the mountain axe. However, there was still a great gap between the mountain axe and the iron dragon axe.

"Open the sky!"

With a roar, Yang Tianjun suddenly split the mountain axe in his hand. There was no escape, but to hit hard.

The three movements of opening the sky have infinite power. The most important thing is to forge ahead. Even if you die, you must not shrink back.

At the beginning, Pangu opened the sky. Even if he knew it would cause great harm to himself, he would never shrink back.

"Boom!" with a loud noise, two giant axes collided with one big seal instantly. Originally, the strength of iron dragon slaying was dominant. However, Yang Hongwu was not weak. He had the power of array and the supreme treasure cangsheng big seal. Although cangsheng big seal's attack power was not as strong as Dragon slaying axe, cangsheng big seal had a great advantage, That is, it can mobilize the power of ordinary people in the big world.

At the moment of collision, the three treasures burst out a terrible impact.

The ground, which had been destroyed by the battle between Yang Hongwu and iron slaughtering dragon, was once again devastated.

In this collision, the iron dragon was shot out, and Yang Hongwu and Yang Tianjun's father and son had the upper hand. After all, Yang Hongwu's strength was equal to that of the iron dragon. Even if he had a slight upper hand, he would not be much weaker. In addition, Yang Tianjun's attack was not weak, so the iron dragon was shot away.

"Poof..." tie Tu Long spit out a mouthful of blood and stared at Yang Hongwu. "Very good, really good. You have successfully angered me."

Yang Hongwu said coldly, "so what?"

In fact, iron slaying dragon has long been angered.
