The valley with no grass, the dilapidated buildings, and the gloomy atmosphere, this is the ruins of the Zhenwuguan where the Taiyin and cold are located.

It was almost midnight, but Tang Jinglin drove Dabai down from the sky and came to this place that can be called a Jedi.

"The last time I came here, I cleaned up the Taiyin and Cold Veins that were entrenched on the ground here, and now they are about to condense again, and it seems that the Taiyin and Cold Veins underground are really about to erupt. This time, I'm going to use the Taiyin and Cold Evil here to complete the second Nirvana, and it's a bit dangerous!" Tang Jinglin thought to himself.

"Master, it's so comfortable, I feel the smell of food!" Da Bai said to Tang Jinglin suddenly.

"Food! Is this what you are talking about?" Tang Jinglin's heart moved, and there was a hint of too gloomy and cold.

Feeling the Taiyin and cold that entered his body, Da Bai's eyes lit up, and he said happily: "Master, this is it! I feel that this kind of energy is very good for me, and it can even further activate and purify my true dragon bloodline, promote my growth, and improve my strength." ”

"It seems that Dabai's bloodline is actually a water genus that is more yin and cold, and it will be easy to do now! The true dragon, phoenix, and unicorn are the three auspicious rays, and they also have the ability to purify heaven and earth, so it is not surprising that they can devour the Taiyin and cold evil. Just like the [Ancestral Dragon Golden Body], the power of the leylines and the yin and evil qi are both food. ”

Thinking of this, Tang Jinglin smiled slightly, and instructed Da Bai: "I will also use this energy to break through later! When I broke through, you entered the Taiyin Cold Evil Cave with me, and while protecting the Dharma for me, you absorbed the Taiyin Cold Evil. If you see that my situation is not right, take me out of the Taiyin and cold acupoints directly. Got it?"

"Okay, master!" Dabai nodded in understanding.

"Whew!"

A yellow light shot into the ground, and both the stone ruins and the hard earth beneath were like melted butter, until a hole with a tumbling blue-black mist was revealed.

Under Tang Jinglin's spiritual eye technique, the golden reticulated seal had been eroded and crumbling here.

Taking a deep breath, the Xuantian Treasure Mirror flew out, and the blue-gold mirror light shone on the golden light net. With the help of the mirror light, the golden light net instantly became golden, and the original damaged places began to be repaired.

Correspondingly, Tang Jinglin could feel that the Xuantian Treasure Mirror was taking over control of part of the Golden Net.

This is the most powerful auxiliary function of the Xuantian Treasure Mirror, which has a great suppression and assimilation effect on all kinds of formation bans.

After the golden net with a radius of about ten meters was completely controlled by the Xuantian Treasure Mirror, Tang Jinglin waved his hand, and the Xuantian Treasure Mirror automatically merged into the golden net. With this strongest treasure, if an accident happens later, Tang Jinglin will also have an extra boost, and it can help him enter the Taiyin Cold Evil Cave below without breaking the golden net seal.

"Da Bai, let's go down!" Tang Jinglin jumped forward, silently passed through the golden net, and fell into the Taiyin and cold acupoints.

Da Bai and Tang Jinglin fell almost at the same time, and their bodies circled around Tang Jinglin a meter away, firmly protecting their masters.

As soon as he entered the Taiyin Cold Evil Cave, the tumbling Taiyin Cold Evil all rioted, and the thick blue-black mist seemed to have a life of its own, desperately drilling into Tang Jinglin and Da Bai's bodies.

"Boom!"

A purple flame bloomed, enveloping Tang Jinglin in an instant, turning into a huge fireball, and all the blue-black Taiyin and cold demons became the fuel of the purple flame.

Da Bai looked curiously at the purple flame spreading outside his master's body, it felt the powerful power of this flame, but now it was completely surrounded by purple flames, and it was not harmed in the slightest.

Soon, as if provoked by the purple fire, a terrifying pressure suddenly appeared, and the expanding purple flame immediately began to rebound, compressing inward, becoming an egg-shaped fireball, and the color of the purple fire became a little darker.

At this time, there was too much yin and cold to rush towards Dabai. I saw that the blue-black light curtain bloomed from its dragon body, and the blue-black Taiyin and cold slowly merged into the light curtain, absorbed by the milky white dragon scales, turning into wisps of strange and mysterious lines, refining its dragon body.

In addition to this, Da Bai also opened his mouth widely, and one after another was too cold and cold to disappear into his mouth, and was swallowed and absorbed by a blue-black bead. This is its inner pill, the foundation of its future transformation into Jiaozhu and Dragon Ball.

Purple qi flew out from the purple fireballs outside Tang Jinglin's body and submerged into the side wall of the cave entrance, transforming the yin soil formed by the erosion of the Taiyin and cold for thousands of years into a cubic of top-grade spiritual soil. With the generation of the best spiritual soil, the golden light source of merit with the thickness of the little finger continued to sink into Tang Jinglin's purple mansion and dantian, strengthening the soul and enhancing the purple fire.

Of course, Tang Jinglin couldn't care about these at this time. The surging true qi was continuously refined by the purple fire, and after being transformed by the meridians, it merged into his dantian qi sea, strengthening the cyclone that had already reached its limit.

"Click!"

Some kind of bottleneck was broken, and the purple cyclone in Tang Jinglin's dantian that had already reached a limit became larger again, and it turned out that his dantian was suddenly expanded by a large circle of space, which could accommodate twice as much Taiyi Xuanguang True Qi.

When the purple cyclone grew to the limit again, a fine purple light bloomed from outside Tang Jinglin's body, and the purple cyclone in his body seemed to be under great pressure, and it was quickly compressed again, until it was one-third of its original size.

However, the purple cyclone that was originally cloud-like had doubled its density at this time, which meant that the quality of Tang Jinglin's Taiyi Xuanguang True Qi had doubled again.

With the breakthrough of the Three-Life Nirvana Secret Technique in the [Taiyi Xuanguang Sutra] to the level of the Second Nirvana, Tang Jinglin could feel that his strength had increased again, and the quality and quantity of his True Qi were probably not inferior to the vast majority of cultivators in the early and middle stages of foundation building. If he faces Zhao Yu now, with his own powerful equipment, Tang Jinglin already has three points of confidence to win, and self-protection is not a problem.

After this breakthrough was completed, it was very strange that Tang Jinglin did not have the feeling of being fed and full in the past, so he simply continued to refine the Taiyin Cold Evil, quickly replenishing and enhancing his true qi cultivation.

"Aang!"

About a quarter of an hour later, a dragon's groan, which seemed to be similar to Da Bai's roar, sounded from under the Taiyin Cold Evil Cave, and directly entered Tang Jinglin and Da Bai's souls, but the ears, which were hearing organs, could not receive it.

Obviously, this cry originated from the soul, it was issued with spiritual power, and it carried a huge spiritual pressure, which was very similar to Dabai's Long Wei.
