The secret water cold pool itself was very cold, and after entering the secret room, the cold was even more obvious, and the surrounding aura seemed to be condensed into frost, extremely rich.

Tang Tian walked to the futon in the secret room, sat down cross-legged, absorbing the surrounding spiritual energy, the Kunpeng Heaven Devouring Gong unfolded, and the spiritual power in the secret room was immediately swallowed up by Tang Tian and drilled into his body.

"Ling'er, this icy cold aura won't have any effect on Kunpeng Heaven Swallowing Gong, right?" Tang Tian thought about it, and still asked Lan Ling'er.

"No, but the cold spiritual power cultivated here is inevitably a little weak, I think you can absorb the surrounding spiritual power and form a spiritual core in your body. ”

"Why?" Tang Tian was stunned for a moment.

"The cold aura here is extremely pure, but even if you really let the cold aura attached to the spiritual power, it won't help you much, but if you condense it into a spirit core and constantly oppress it, making the cold aura more and more pure, it will help you a lot. ”

"You can let your spiritual power explode through the spiritual core, so that your spiritual power has a more obvious and prominent cold spiritual power. Lan Ling'er said with a chuckle.

"Okay, then do as you say, but how should this cold spirit core condense?" Tang Tian was a little puzzled.

"You use the Kunpeng Heaven Devouring Gong to absorb the surrounding spiritual energy, and I control the spiritual power in your body to help you condense the icy spirit core. "This matter is extremely troublesome to say, Lan Ling'er simply helped Tang Tian directly.

Tang Tian naturally wouldn't refuse, and if he did it himself, he didn't know if he could finish it in a month.

Then Tang Tian used the Kunpeng Heaven Swallowing Gong to absorb the spiritual energy in the secret room, but the secret room was too small, and the spiritual power was empty as soon as he inhaled it, and he could also feel the subtle changes in his dantian, and a small spiritual core appeared in his dantian.

The spirit core revealed an extremely cold aura, as if it could freeze a person to death.

Seeing that it had worked, Tang Tian worked harder to absorb the spiritual power in the room, and his own cultivation was also slowly improving in the continuous absorption of spiritual power.

Half a month passed, and the icy spirit core also grew, and it was like a speck of dust before, but now it was the size of a soybean.

"Tang Tian, if you continue to cultivate like this, I'm afraid that before the end of the month, the Ice Cold Spirit Core will not be able to truly succeed, and you will have to find a way to absorb more spiritual energy. Lan Ling'er's voice was unusually serious.

Tang Tian also frowned slightly when he heard this, and looked left and right.

The secret room was completely sealed, and the aura was fed in through the formation, and when he was outside before, Tang Tian also felt that this cold aura seemed to come from some special place.

"Can you find out the root of the aura? Tang Tian asked in a deep voice.

Lan Ling'er fell silent when she heard this, as if she was probing, and it took a long time before she replied to Tang Tian.

"The 800-foot place under the water of the pool is the root, but with your cultivation, I am afraid that you will not be able to enter the most root place, and the 600-foot place should be just right. ”

"What? The root cause is in the pool of water, then why didn't I notice the cold aura before?" Tang Tian couldn't help but be a little surprised.

"Formation reasons, okay, don't talk so much, let's go down quickly. After Lan Ling'er briefly explained, she let Tang Tian enter the pool.

Because it was to help himself improve, Tang Tian didn't say anything, and walked out of the secret room very simply, jumping straight into the pool.

The depths of the pool water are the same as before, and it doesn't look too different, but the deeper you go, the more heavy the cold aura becomes, and there are already sporadic spiritual powers floating in the air, for these spiritual powers, Tang Tian naturally didn't let go of them, and directly devoured them in his body.

800 feet seems to be very deep, but in fact, it will take a few minutes to arrive, but Tang Tian listened to Lan Ling'er's words and stayed at 600 feet, and this place was extremely cold and aura, Tang Tian even saw the Spirit Gathering Array at 500 feet, it was the Spirit Gathering Array that devoured the spiritual power and teleported it to the various secret rooms.

"It's right here, cultivating here for half a month, it should be able to completely form your cold spirit core. Lan Ling'er said with certainty.

Tang Tian also laughed when he heard this, and Kunpeng Swallowing Heaven Skill showed off, directly swallowing all the spiritual power within a hundred feet of the surrounding area into his body.

"You seem to be a fool!" Lan Ling'er was a little angry when she saw this scene.

"What's wrong. Tang Tian touched his head, a little unclear.

"Don't you think about those people above?, if they can't absorb spiritual power, they will naturally sense that something is wrong, and report it to the sect elders when the time comes, what will you do when the elders come down to investigate?!" Lan Ling'er said with some annoyance.

Tang Tian couldn't help but touch his nose in embarrassment, because seeing the rich cold aura around him, he was inevitably a little excited in his heart, so he directly devoured the surrounding aura, but he forgot to think about this aspect.

"I'll pay attention to ...... next," Tang Tian said with some embarrassment.

Lan Ling'er didn't bother to pay attention to him, and directly helped Tang Tian start to condense the spirit core, Tang Tian was a smart person, she only needed to order a sentence, and the other Tang Tian was naturally measured.

So there was a strange scene under the pool, half of the spiritual power in the pool would always be swallowed up, leaving only half of the spiritual power to be sent to the many secret rooms by the spirit gathering array, and the amount was suddenly reduced by half, and those who cultivated in the secret rooms were naturally aware of it.

"It's strange, why did the spiritual power suddenly decrease? But it's okay, it's just enough for me to absorb, so I'll leave it alone for the time being. ”

"Isn't there something wrong with this pool? When I go out, I'm going to tell the elders to go and investigate under the pool!"

"There is still half a month to go in the outer gate qualifying competition, although the spiritual power is less, but it is still enough, there is not much time to delay now, let's seize the time to cultivate." ”

A burst of screams came from the various secret rooms, but none of them took the initiative to contact the elders, because they were all afraid of delaying their time, the outer door qualifying competition would determine their status and the resources they could receive every day, and they naturally wanted to race against time to improve their strength.

Such an idea made Tang Tian feel a lot more comfortable and saved a lot of trouble.

When the 29th day passed, Lan Ling'er's excited voice sounded in Tang Tian's mind, but there was still a trace of exhaustion in her voice.

"Tang Tian, it's a success!"

Hearing this, Tang Tian hurriedly looked inside his body, and then found that at his dantian, a crystal clear ice ball was spinning constantly, and slowly releasing cold qi affecting his spiritual power, which looked extremely beautiful.

"Okay Tang Tian, you go out and find a place to test it yourself, this time it consumed too much of my strength, I'll rest first." ”

As soon as the words fell, Lan Ling'er fell into a deep sleep.
