The spiritual energy cannon was a huge cannon made of mysterious black metal. The cannon and the cannon combined were almost as tall as Chen Feng, and the barrel was about two meters long!    

    

When the spiritual energy cannon appeared in front of Chen Feng, he could feel a destructive aura spreading out in all directions!    

    

As for the old man in green, he could clearly feel it!    

    

In an instant, he felt his muscles contracting, followed by the feeling of death!    

    

Moreover, he actually felt a pair of eyes staring intently at him from behind. It was this pair of eyes staring at him that caused him to have a premonition of death!    

    

What was even more terrifying was that there was actually an extremely frightening destructive aura filling the entire space. It caused one's heart to involuntarily tremble when they sensed this destructive aura. Both of their legs trembled!    

    

"What's going on?!"    

    

As a Martial Emperor expert, Zhang Tongyi had not felt this kind of aura of death for half of his life. The first time was when he was once again a Martial Grandmaster stage. He only felt it when he was being chased by a genius of the same generation.    

    

However, that genius was killed by his means. In the end, he seized the opportunity of a genius and broke through to Martial King's stage. After that, he broke through again and again. In less than half a year, he had reached the Martial Emperor realm. He was now Elder in the Rushing Thunder Sword Sect, and was only a step away from establishing his own sect!    

    

But now, he actually felt the fear of going against his will for a long time, and even the threat of death!    

    

"Just who is it that has such a powerful immense momentum!? Is it that Demonic Beast?!" Zhang Tongyi sensed the aura on Zhang Jiuling's body and instantly overturned his guess!    

    

"The owner of this immense momentum is someone else!"    

    

In an instant, Zhang Tongyi sensed the source of this destructive aura!    

    

It was behind a huge rock!    

    

"Who is it that wants to harm me?!" Zhang Tongyi's expression changed. Although he was guessing in his heart, he instantly turned around and fled into the distance!    

    

"Flee!"    

    

Zhang Tongyi could already feel the power of this aura. It was an absolute destructive power that even he could not resist!    

    

He could sense that he would absolutely die under the hands of the owner of this aura without any ability to resist!    

    

However, what he did not know was that this aura was not from the Cultivator. It was just a cannon!    

    

However, if he knew that just a cannon had such a destructive aura, he would be even more surprised!    

    

In an instant, Chen Feng looked at Zhang Tongyi's fleeing figure and placed his palm on the spiritual energy cannon. In an instant, the cannon crazily absorbed the spiritual energy of heaven and earth and then condensed in the cannon barrel, like a cannonball!    

    

In an instant, Zhang Tongyi felt that the premonition of death was getting stronger and stronger, and the destructive aura was getting stronger and stronger!    

    

In the next moment, the spiritual energy in the spiritual energy cannon had already gathered to the extreme!    

    

The corner of Chen Feng's mouth raised slightly, and he said softly, "Spiritual energy cannon, fire!"    

    

Fire!    

    

Boom -    

    

The spiritual energy cannonballs shot out of their barrels and instantly dispersed the surrounding air. In an instant, the surrounding space distorted and distorted due to the high temperature!    

    

Almost instantaneously, Boom! Boom! The spiritual energy cannonball had already caught up to Zhang Tongyi who was driving the flying sword!
