However, before Li Tian could respond, a loud phoenix sound suddenly came from above.

Immediately afterwards, the powerful Qicai Fengluan also came to the ground, but its size had changed, and it had shrunk by about two hundred times.

"Damn human beings, how dare to break into my lair!" Feng Luan shouted sharply, with a very violent aura. As soon as it entered the lair, it immediately discovered the breath of outsiders.

The most obvious thing is that the channel connecting the earth veins has been opened, and this means that someone has definitely visited the earth.

Qi Cai Fengluan's gaze swept over, and his whole body exuded a violent bloodthirsty aura. There is no doubt that if it is allowed to spot the intruder, it will definitely take the initiative in the first place and kill it with the momentum of thunder.

But after searching for it, it didn't find any figure, only saw the giant python that the veins turned into, and the remaining strange aura.

"Is it already gone?" Qi Cai Fengluan's eyes flickered, and the evil aura in her eyes had abated, especially when it was certain that this earth vein had not been depleted.

Thinking of this, Qi Cai Fengluan was ready to return, but before leaving the ground, it suddenly remembered something, opened its mouth and spit out a huge pillar of fire, and blasted in the direction the python was staring at.

"Boom!" There was a violent impact, and the underground world trembled. The rocks were broken and splashed and scattered everywhere.

Some gravel hit the giant python, the latter roared suddenly, turned to stare at the colorful Fengluan, and then it condensed blood and directly threw out a bright red horse.

Practicing speed is extremely fast, like a shuttle space, instantly came to Qi Cai Fengluan, and bumped into it.

Qi Cai Fengluan gave a soft cry, and condensed a layer of flame shield to resist the horse, while its eyes were still fixed on the place where the fire pillar hit.

Just now, it saw that the fire python looked wrong, so it tried, but there was no problem.

"Really gone?" Qi Cai Fengluan looked suspicious, but in the end, it turned back and flew into the nest above.

But it didn't take long before it swooped down again, and its eyes swept across the ground again, and after repeated investigations did it let go of its doubts.

Seven or eight feet away from Qicai Fengluan, one person and one snake looked nervous, and above them, a transparent light curtain was hidden in the void.

After a while, Qi Cai Fengluan left the ground again and returned to its own lair. Li Tian and the black water snake breathed a sigh of relief, and their hanging hearts gradually let go.

"This animal is really cunning." Li Tian wiped his sweat, and when he looked back, the rock wall behind him was shattered, and the remaining flames were burning faintly.

A dozen or so breaths ago, the pillar of fire that Qi Cai Fengluan spit out was indeed blasting towards them, but the trajectory of the pillar of fire was deflected, wiping the light curtain in the void, hitting the rocks behind.

If it weren't for this, one of them and one snake would inevitably show up, unable to continue to hide their figure, and the final result would naturally be that Feng Luan was powerfully bombarded and killed.

"Thanks to Brother Tian's formation." The crisis was resolved, and the black snake quickly calmed down, shyly touting.

"That is, based on my knowledge of the formation, it is not difficult to set up a large formation to hide the figure!" Li Tiangao raised his chin, his expression complacent.

"Brother Tian is still amazing!" The black snake continued to praise, but it was contemptuous in his heart. Li Tian also had a frightened expression just now, not much calmer than it, which shows how powerful this formation is.

The reason why Qi Cai Fengluan can be concealed is only because the latter's consciousness is too weak to perceive the weak formation fluctuations. If it is changed to another monster, the result will be unpredictable.

"Well, we will stay here for a few days. When Fengluan leaves, we immediately escape from its lair." After a while, Li Tian interrupted the flattery of the snake.

The black snake nodded, then hovered, quietly in a daze, Li Tian was bolder than it, and dared to absorb the blood in the formation.

Of course, Li Tian also restrained, and did not arbitrarily pull the blood, so as not to alarm the colorful Fengluan above.

But at this moment, he suddenly felt that the aura exuded by Colorful Fengluan seemed to become very disordered.

Not only that, the cultivation level of Qicai Fengluan also dropped a lot at this time, even lower than before it started Nirvana.

"What's the situation?" Li Tian was startled, and then he let out his spiritual perception, wanting to know what happened.

Due to the huge aura of Qicai Fengluan, the black dragon snake was also aware of it, and it subconsciously said, "Wait, the Nirvana of Qicai Fengluan did not seem to be successful!"

"Nirvana failed?" Li Tian was taken aback for a moment, and then asked aloud, "Then why can it recover from its injuries and improve its own strength?"

"It's still because of Nirvana. Let's put it this way. Nirvana is actually not a complete failure, but it did not achieve the expected results."

The black snake replied in a deep voice, "I want to come, this time Nirvana is too abrupt, it is not prepared at all, and naturally there will be problems."

"Next, it will need to perform Nirvana again to make up for the defects it left behind, but the difficulty of Nirvana will be greatly increased, and it will also require huge energy support."

"Huge energy..." Li Tian muttered, then he turned his gaze to the giant python.

In the entire lair, the most energy-contained ground vein is naturally this weird shape. If Qi Cai Fengluan lacks energy, the only way is to extract it from the ground vein.

Before long, Qi Cai Fengluan, whose breath was disordered, came to the ground again, staring eagerly at the python.

The giant python had a sense, a pair of scarlet eyes staring at Qi Cai Fengluan, the two auras of different attributes were also rising constantly, and a slight collision occurred.

Among the formations, one person and one snake were watching the show with a strange expression. Li Tian asked casually: "Is this going to fight?"

"There should be nothing wrong. The giant python gives me a very special feeling, but it definitely has intelligence and will not be swallowed willingly." The black snake replied.

Unsurprisingly, waiting for the next moment, Qi Cai Fengluan took the lead and opened his mouth to spit out a splendid rain of fire.

The mighty power erupted, flooding the entire underground, and the destructive power engulfed in the fire and rain reached a very exaggerated level. The rocks along the way were all melted instantly.

On the other side, the giant python roared sharply, and the huge energy of blood also condensed in an instant, turning into a thick blood-colored barrier, completely blocking the rain of fire.

The fire rain fell on the blood-colored barrier and suddenly released all the energy, dissolving the barrier extremely fast, but the energy carried by the barrier was not low, and it finally persisted without being broken.
