Looking at the thunder that fell this time, Xuan Lao, who had always maintained an indifferent look in the distance, changed color, and said in surprise: "This is actually the Heart Demon Tribulation? A Tianzun can actually cause such a calamity?", the words were full of solemnity, obviously he was extremely surprised by the thunder punishment that fell this time.

Heart Demon Tribulation, a kind of calamity that all martial artists will encounter when they practice, this kind of calamity may not appear in what realm, but from ancient times to the present, those who generally encounter this kind of calamity are at least martial artists in the Sage Realm, and they have never heard of someone who can trigger this kind of calamity in the Tianzun Realm.

The heart demon tribulation is not an ordinary thunder punishment, it is a calamity caused by the warrior's own heart demons, you know, everyone has a variety of desires in their hearts, and this desire is intertwined, it will produce heart demons, and even in other words, the stronger a warrior's cultivation is, then the stronger the heart demons he has to face.

At this moment, Chen Yu's Heart Demon Tribulation was completely triggered, and with his current cultivation, he was enough to stand side by side with Chen Jinglun and other old qualified Heavenly Venerables, and when the Heart Demon Tribulation appeared, even Xuan Lao was shocked.

"The robbery is born from the demons in the heart, and the five elements are manifested. Xuan Lao muttered, he resounded that he had triggered the Heart Demon Tribulation shortly after stepping into the Sage, and if it weren't for his firm heart, he would have died in the Heart Demon Tribulation.

If you want to survive the inner demon tribulation, in addition to having enough cultivation, your heart must also be firm enough, after all, the inner demon is generated from your own heart, that is, you have to face another self.

The black thunder fell, and did not spread, but converged into one point, and all fell on Chen Yu's body, condensing one black lotus flower after another, the most terrifying thing is that these black lotus flowers are like flames, exuding a terrifying temperature, this is one of the heart demon tribulations, the Netherworld Tribulation Fire!

This kind of flame is extremely terrifying, once ordinary people are contaminated with a trace, they will fall into the realm of no return, because this kind of netherworld fire can completely release the demons in the hearts of the warriors.

Chen Yu's whole body was shrouded in the black Netherworld Tribulation Fire, and his face showed pain, and he wanted to use his own strength to destroy these flames, but he found that whether it was the Yuan Force in his body or the manipulation of the Heaven and Earth Energy of the outside world, once he was contaminated with the Netherworld Tribulation Fire, he would be incinerated.

At first glance, hundreds of thousands of Netherworld Tribulation Flames bloomed on Chen Yu's body, these Tribulation Flames took the shape of lotus flowers, which was very strange, each one contained extremely terrifying power, which could not be extinguished, and could only be allowed to burn.

Chen Yu's body began to undergo strange changes since it was contaminated with the Netherworld Tribulation Fire, and his body withered at a speed that was visible to the naked eye, just like the blood and qi in the entire human body, and his cultivation was burned to the end by this Netherworld Tribulation Fire.

And Chen Yu showed a painful look on his face, but there was nothing he could do, his eyes were closed and never opened, because the Netherworld Tribulation Fire appeared, and the demons in his heart had already appeared, and he couldn't deal with these Netherworld Tribulation Fires at all, so he could only let his body wither.

"Boom"

A cyan divine thunder fell from the dark and heavy thunderclouds again, and everywhere it passed, even the space was cut apart, and since this cyan divine thunder appeared, the entire Blackwood City felt a sudden gust of wind blowing outside.

The cyan divine thunder fell on Chen Yu's body, and there was no abnormal change, except for the unprovoked wind, but Xuan Lao had been observing, and he found that since the cyan divine thunder fell, the netherworld calamity fire on Chen Yu's body had become more vigorous, and the lotus-like calamity fire seemed to have increased several times.

"Wind and Fire Heart Demon Tribulation!"

Xuan Lao muttered softly, his face was incredulous, the Heart Demon Tribulation actually distinguishes the five element attributes, with the strength and weakness of the martial artist's cultivation, the ordinary sages are all single attributes in the Heart Demon Tribulation, but Chen Yu is the Heart Demon Tribulation with two mixed attributes, which makes him not worried.

"The wind fuels the fire, and it's terrible. Xuan Lao secretly screamed in his heart that it was not good, at this time the Heart Demon Tribulation was already very powerful, even if it was Xuan Lao, he would not dare to touch it, even if it was contaminated with a trace, then he himself would cause the Heart Demon Tribulation again.

Indeed, as Xuan Lao thought in his heart, the Netherworld Tribulation Fire at this moment had become even more terrifying, and at some point in the surroundings, there were already countless small tornadoes forming, constantly fueling the Netherworld Tribulation Fire to become more vigorous.

After an instant, Chen Yu's whole person seemed to be completely burned by the Netherworld Tribulation Fire, evolving into a living person, and the small tornadoes evolved from those cyan divine thunders continued to blow back and forth around Chen Yu, fueling the Netherworld Tribulation Fire to become more vigorous.

In an instant, even Chen Yu's space within a radius of 100 miles was burned to the point of collapse by the Netherworld Tribulation Fire, and Chen Yu was the whole person was in a state of extreme pain, fighting against his own inner demons in his heart, while his body was constantly burned by the Netherworld Tribulation Fire, if he couldn't get rid of the inner demons, then Chen Yu's final fate was to be burned to nothingness.

The rest of the remaining Heavenly Venerable Martial Artists could only avoid it from a distance, and the Wind and Fire Heart Demon Tribulation did not affect them, because this was the thunder punishment that Heavenly Dao landed on Chen Yu alone, but they did not attack Chen Yu, they didn't dare, and in fact, there was no way to make a move, because the moment Chen Yu appeared in the Wind and Fire Heart Demon Tribulation, the terrifying Netherworld Tribulation Fire, and the tornado formed by the cyan divine thunder, enveloped Chen Yu's space within a radius of hundreds of miles, and they couldn't even get close.

Although they didn't know what the Heart Demon Tribulation was, but seeing the lotus-like Netherworld Tribulation Fire torturing Chen Yu into this appearance, no one present was willing to be contaminated with these things.

"Oops, this is the Heart Demon Tribulation, it looks like it's still a dual-attribute Heart Demon Tribulation!"

At this time in the city of blackwood, the fighting god monk saw this scene, greatly disgraced, as a sage and martial artist, he has already suffered such a terrible thunder punishment, naturally he knows how terrifying the heart demon tribulation is, if he didn't practice the heart of the Buddha sect back then, it has a magical effect on the heart demon, and he can't survive the heart demon tribulation.

"What is the Heart Demon Tribulation? Looking at the appearance of the monk, it seems to be a very terrifying thing. Chen Feng frowned and asked, for some reason, he saw those Netherworld Tribulation Fires, and there was a chill in his heart.

The Fighting God Monk sighed, and 1510 told everyone the origin of the Heart Demon Tribulation, this is usually Lei Jie, which can only be triggered by sages and martial artists, but at this time, it was Chen Yu who triggered it at this time, which is really indescribably weird.
