Lu Chen stared at the dark clouds in the sky. The dark clouds in the sky regrouped and formed a second wave of thunder, which was much more powerful than the first wave.
"Brother Lu, be careful. Grandpa said that the first few waves of lightning tribulations are just for tempering the human body, and the subsequent thunder tribulations are the real danger."
Nan Tian Wan'er reminded Lu Chen that since the two consciousnesses merged into one, she could know what Lu Chen was thinking without thinking.
"Wan'er, I understand, the second wave of thunder tribulation is coming." Lu Chen said as he looked at the thunder tribulation that was about to fall in the sky.
The thunder tribulation fell, and its power was much greater than before. Lu and Chen still relied on their bodies to resist.
One wave, two waves, three waves...
Five waves of lightning tribulations fell in a row. The lightning tribulations fell faster and faster, and their power became stronger and stronger.
The sixth wave of thunder tribulation ended, and Lu and Chen fell from the sky, their bodies still wrapped with lightning.
"It seems we need to take it seriously. The power of thunder tribulation can already harm our bodies."
Lu Chen waved away the electric light on his body and took out the Great Sword of Hunyuan to fight against the thunder calamity. At this moment, the dark clouds in the sky suddenly dissipated.
"Brother Lu, look, the clouds have disappeared."
Lu Chen looked at the sky. The dark clouds in the sky had disappeared and there was no trace of the power of the thunderstorm before.
"It shouldn't be. There are twelve waves of Qi Drinking Thunder Tribulation. This is the rule of the Heaven and Earth Avenue that cannot be changed." Lu Chen stared at the sky and thought about the reason.
Not far away, Nan Tianxiu saw the thunder calamity disappearing and was about to go back, when a sudden change occurred.
A larger thunderstorm condensed in the sky, covering the entire secret realm, and the center was in the direction of Lu Chen.
Everyone who was hunting for treasure in the secret realm put down what they were doing and raised their heads, staring at the dark clouds.
"Thunder Tribulation? What kind of thunder calamity is this? The power of the clouds is so great."
"Which powerful person has broken through the realm in this area? Will the thunder tribulation affect us?"
"Could a strange treasure be born?"
For a time, people all over the secret realm had different opinions, and they carefully speculated on the source of the thunder disaster.
"Second uncle, is there a strange treasure over there? Should we go and see it?"
Master Jun and Nan Tian Yijian, who were looking for treasures in the valley, noticed the calamity cloud in the sky and shouted to Jun Wudi.
"We can't go. There are monsters from ten thousand years ago in this secret realm. The calamity cloud must have awakened these monsters. We must find the medicinal herbs as soon as possible."
In the past few days, Nantian Yijian and Master Jun have been collecting treasures in the secret realm, and their cultivation has become even more advanced.
Nantian Yijian has entered the eighth level of the Qi Drinking Realm, and with the support of many treasures, the spiritual energy in his body has begun to turn into liquid.
Master Jun has successfully generated a drop of spiritual liquid in his body, and is waiting for the spiritual liquid to complete its circulation in the body to overcome the thunder tribulation.
…
Deep in the valleys of various places in the secret realm, sleeping high-level monsters were awakened, and they all stuck their heads out to look in the direction of Thunder Tribulation.
"The center of the thunder tribulation is in Hell. Could it be that this old guy, Balrog, has advanced in cultivation?"
The leaders of metal, water, fire, and earth communicated with each other in their homes.
"It's not me who advanced. There are humans coming in from the secret realm. It's the humans who are going through the tribulation. It's even more terrifying than our advanced thunder tribulation." Yan Mo said slowly, feeling the aura of his own territory.
"What...human beings? You're not mistaken, are you? With so little spiritual energy in the world, how can humans have such a strong aura?" The other leaders obviously didn't believe it.
"Where's the wind dragon? Why is there no news about the wind dragon?" The Balrog was closest to the wind dragon's territory and he couldn't feel the wind dragon's breath.
"The breath of the wind dragon has disappeared. There seems to be a battle over there." After the Balrog explored, he quickly said to several other monsters.
"Humans, they must be humans. I want to drive them out of the secret realm." After a monster leader said this, he stopped talking and began to instruct the monsters to drive away the humans who entered the secret realm.
"I want to go too. We can't let this group of humans destroy the secret realm of the Sixth Patriarch." The remaining demon beast leaders also began to organize the demon beasts to drive away the humans.
For a time, the monsters in the secret realm went berserk and began to attack the humans who entered the secret realm.
"Run quickly, the monster beasts are coming. I don't want to die here." The low-level practitioners began to escape from the secret realm.
…
The clouds in the sky are already very thick, and the thunder in the clouds is like a horned dragon.
Lu Chen did not dare to underestimate the thunder and lightning this time. He put on his defensive magic weapon and raised the Hunyuan Giant Sword with both hands, quietly waiting for the thunder and lightning to arrive in the sky.
"boom……"
The thunder calamity fell again, the huge thunder dragon coiled around wantonly, and the light shone throughout the secret realm.
"Wan'er, it's time to go."
"Drink! Green Emperor Sacred Tree"
"The silver snake comes out of the cave"
"The dragon descends into the sea"
Lu Chen flew up and condensed a layer of Qinghuang Sacred Tree tentacle defense on the outermost layer above his head, followed by two layers of phantom defense.
"Boom...boom...boom..."
The thunder dragon bombarded the shield formed by the Green Emperor Sacred Tree. With only a slight obstruction, the thunder dragon directly smashed the Green Emperor Sacred Tree into pieces.
The two phantoms were unable to stop the Thunder Dragon, and they were all shattered by the Thunder Dragon's bombardment.
"Boom..." The thunder dragon flashed a black beam and rushed towards Lu Chen.
"bring it on"
Lu Chen shouted loudly, raised the Hunyuan giant sword and rushed towards the thunder dragon.
"Boom..." Black lightning instantly surrounded Lu Chen.
"Hunyuan giant sword, cut."
Lu Chen swung his giant sword in the thunder and struck continuously.
The wind dragon woke up from his drowsiness and attached himself to the Hunyuan giant sword with a violent aura.
"kill"
Lu Chen grasped the Hunyuan Giant Sword with both hands, raised it above his head, shouted and slashed hard at the Thunder Dragon.
"boom……"
The Hunyuan giant sword hit the violent aura and directly split the thunder dragon into two pieces from the middle, dissipating between the heaven and the earth.
Lu Chen fell back to the ground and looked at the giant sword in his hand.
"This is such a good sword. It withstood a thunderous strike without leaving any trace."
"Brother Lu, are you okay?" Nantian Wan'er said worriedly as she looked at Lu Chen who was resisting the thunder dragon.
Nantian Wan'er has been frail and sick since she was a child. She was infected with cold poison after she started practicing martial arts. For her, martial arts training was completely blank.
"It's not a big deal, I can still resist a few more times. Just protect yourself down there." Lu Chen sat down on the spot and began to recover his spiritual power and wait for the next wave of thunder.
For an entire hour, the brontosaurus regrouped in the sky.
Lu Chen stared at the Thunder Dragon in the sky and noticed that the Thunder Dragon's horn turned fiery red, revealing its blazing firepower.
"Sky Fire Thunder Dragon? How could such a catastrophe happen in the Qi Drinking Realm?"
"Is the world afraid of me? This is impossible. We are just monks in the Qi Drinking Realm."
Lu Chen repeatedly recalled Fengtian's memory. The only tribulation under the Chongtian realm was the Heavenly Thunder Tribulation, while the Heavenly Fire Tribulation could only occur when the Chongtian realm transcended mortals and transformed into immortals.
Different from the Heavenly Thunder Tribulation, the Heavenly Fire Tribulation is completely a method used by the heaven and earth to fear and eager to kill those who have overcome the calamity.
Lu Chen stood up and continued to gather his spiritual energy.
"boom……"
The thunder dragon fell, accompanied by blazing flames, and the fire dyed the entire secret realm red.
"Heavenly Fire Tribulation? How could there be a Skyfire Tribulation?"
Nan Tianxiu stared at the falling Sky Fire Thunder Dragon with some shock. He had already transformed into an immortal eight hundred years ago.
At that time, he had been preparing for a thousand years to survive the Heavenly Fire Tribulation, and even used all the Nantian Sect's efforts to set up formations to survive. Now that he recalls how he looked when he overcame the calamity, Nan Tianxiu is still frightened.
"Heavenly Fire Tribulation, this is going to cost them their lives. Is Lu Chen's talent already so powerful that the world is afraid of him when he is in the Qi Drinking Realm?"
Nan Tianxiu wanted to rush into the Heavenly Fire Tribulation to help Lu Chen resist it, but thinking that one more person would make the Heavenly Fire Tribulation even more powerful, Nan Tianxiu had no choice but to hold back and rush in.
…
Lu Chen looked at the Sky Fire Thunder Dragon that was about to charge towards him, and flew up with the Hunyuan Giant Sword, releasing his strongest defense.
"Fenglong, we're on board."
"let's go."
The wind dragon was attached to the Hunyuan giant sword. Looking at the falling calamity fire, the wind dragon was already ready to stop the calamity for Lu Chen.
"boom……"
The Sky Fire Thunder Dragon fell, and the defensive methods prepared by Lu Chen were ineffective at all.
The Green Emperor Sacred Tree was burned cleanly, the transformed shadow was directly evaporated, the barrier under the spiritual energy was shattered like a silk mesh, and the Skyfire Thunder Dragon was less than a hundred meters away from Lu Chen.
"Roar..." The Sky Fire Thunder Dragon roared, seeming to mock Lu Chen for the weak defense measures he had laid out.
"Xiao Lu'er, use the sword energy to consume the calamity fire energy remotely, and remember that the five elements are mutually reinforcing and restraining each other."
"good"
Lu Chen condensed the cold energy in the Yin Sea Pearl with his hands, and wielded the sword energy to continuously consume the energy of the Skyfire Thunder Dragon.
The Sky Fire Thunder Dragon stopped fifty meters above Lu Chen's head, and its body continued to shrink.
"boom"
The Sky Fire Thunder Dragon's body condensed from dozens of feet to one meter in size, and exploded into countless flames attacking Lu Shen.
"Xiao Lu'er, the real Heavenly Fire Tribulation is about to begin, use the Hunyuan Giant Sword as a shield to resist it." Feng Long shouted to Lu Chen while looking at the scattered Tribulation Fire.
Lu Chen flew towards Nan Tian Wan'er, raised the Hunyuan giant sword and held Nan Tian Wan'er behind him.
"Wan'er, be careful."
The black and white Pisces flew out of the Tianchi, transformed into a Pisces disk and attached to the hilt of the Hunyuan Giant Sword.
"Calling the spirit, go"
Lu Chen quickly made a seal with his left hand against the Pisces plate. This was a method of becoming one with the weapons that Lu Chen learned from his military career.
After the seal was completed, two streams of light, one red and one blue, shot out from the black and white double fish, wrapping around the Hunyuan giant sword and pointing directly at the tip of the sword.
"Bang, bang, bang"
Along with the red and blue flowing light, the Hunyuan giant sword began to decompose and deform, and the sword body grew larger and wider, completely covering Lu and Chen.
The calamity fire fell and was directly blocked by the Hunyuan giant sword, without touching Lu and Chen at all.
"Zizzizi"
The calamity fire attached to the Hunyuan Giant Sword and was burning continuously, but it could not damage the Hunyuan Giant Sword at all.
An hour passed, and the calamity fire slowly disappeared.
"Huh...huh"
Lu Chen withdrew the Great Sword of Hunyuan and lay down on the ground, shouting loudly. This time the Heavenly Fire Tribulation was finally over.
"It's already a calamity of heavenly fire now, and I don't know what calamities there will be in the next two waves."
"boom"
Before Lu Chen could react to the catastrophe of heavenly fire, the clouds in the sky began to move again.
"Boom...boom"
Two lightning beams shot out from the clouds, one on the left and one on the right, and rushed toward the landing.
"A skyfire thunder dragon plus a thunder dragon, and I haven't had time to breathe yet. Are you trying to kill me?" Lu Chen stood up again and shouted toward the sky.
