Ling Feng was overjoyed, although he had suffered great pleasure, but as the system said, this Yin River water was too good for cultivating the exercises of the underworld.

Impact!

Ling Feng howled wildly in his heart, at this moment he had completely ignored it, and forcibly turned on the cultivation mode of the "Soul Suppressing Purgatory Technique", and in an instant, the terrifying Yin and cold qi in the Yin River frantically surged towards Ling Feng, obviously the more this Yin River Qi was poured into the soul body, the more violent his promotion became.

"Okay, very good, you kid really deserves to be the son of Hades, one word fierce!" On the shore, the system soul elder nodded again and again when he saw this scene, obviously quite satisfied with Ling Feng's lifeless energy.

The soul elder next to him was also excited, but he still frowned, worried that Ling Feng would have an accident if he was so crazy.

At this moment, Ling Feng felt that his whole body was cold, but the strange thing was that his body was extremely hot, this heat was the foundation of foundation building, he knew in his heart that if the foundation building was successful this time, then his foundation building strength would probably be unprecedentedly strong, and ordinary people could not compare it at all, not to mention the six major virtual realms joining forces to attack, even if it was six more, it would be like chopping melons and vegetables, all of them could be done.

No matter how strong the martial arts are, compared to the immortal dao, they are just a slightly larger ant!

As soon as he thought of this, Ling Feng was extremely excited, but at this moment, suddenly a cold air came from the north of the Yin River.

"What's going on? Now that the lunar calendar is only in July, why is it suddenly cold? The old soul couldn't help but shudder, and hurriedly looked at the old ghost.

"I don't know, this year's cold spell is ahead of schedule?" The ghost elder scratched his head, also extremely surprised.

"Mention your size, even if it is advanced, where will it break out at this time, this is trouble!" Soul Elder hurriedly looked at Ling Feng at the bottom of the river, at this moment the time was still at the end of summer, although this Yin River was cold, it might not be able to get cold, so Soul Elder agreed to let Ling Feng go down to the river, at least there would be no sinister events.

But now, if the cold air comes from the north and sweeps the entire Yin River, then Ling Feng staying in the Yin River is definitely very dangerous, and he must be quickly asked to get up.

"Hurry up and let him come up, with his soul, it is impossible to block the cold air from the north!" The soul elder settled down and shouted hurriedly.

The ghost elder was also worried at the moment, and couldn't help but take a step forward to look at Ling Feng, and suddenly found that his soul body was flashing with blue light, and then his heart was shocked: "I see, I see, this guy Ling Feng is really a bit unexpected, it seems that his foundation building will be brilliant!" ”

"What do you mean?" The soul is in a hurry, obviously he loves Ling Feng in his bones.

"The main reason why this cold air suddenly swept down was because Ling Feng was crossing the foundation, obviously his foundation building was extraordinary, causing abnormal changes in the heavens!" After the ghost elder finished speaking, the soul elder was a little surprised, and followed closely in his mouth.

"He can only build a foundation, even if it is the Jindan Realm, there may not be such a change, right? Are you looking away? ”

"How could I look away, everything is because of Ling Feng, what this kid did was too rebellious, so Yin He was furious to stop him!" The ghost said in disbelief.

"What then? This Yin River rage is extremely ferocious, Ling Feng is absolutely unstoppable, if he has to advance, he must end it before the cold freezes, otherwise he will end up dead in the end even if he goes against the sky! The soul elder said, the overwhelming cold air has made the entire Yin River covered with a layer of hoarfrost, and the banks of the Yin River are even more white!

"Don't worry, I'll figure it out!" After the ghost elder finished speaking, the entire soul body had floated to the Yin River, obviously he was helping Ling Feng resist this powerful cold qi.

"This old thing hurts Ling Feng more than me!" The soul elder smiled slightly, and immediately soared up.

"What are you doing? Go back quickly, this Yin River stretches for tens of thousands of miles, once the cold air rushes in, the strength is extremely strong, hurry back! Ghost Elder worried.

"With you, what am I afraid of, after all, we are husband and wife, we share blessings and difficulties!" Soul Elder said with a slightly red face.

"You—did you promise?" The old ghost was so excited that he almost didn't fall into the Yin River.

"You're excited!" Soul Elder hurriedly supported him.

"Of course I'm excited, I've asked you to marry hundreds of times, to be honest, I'm already desperate, you actually agreed, can I not be excited?" The ghost old man was so excited that his whole mouth was about to laugh.

"Fool, I'm testing whether your love for me is true or not!" Soul Elder giggled.

"Of course it's true, it's definitely true, I'm so happy!" After the ghost elder finished speaking, he kissed it.

At this moment, Ling Feng at the bottom of the Yin River was about to vomit blood, and his heart said when is this, can you two stabilize the point, Lao Tzu is about to freeze to death!

Above, the soul elder seemed to hear Ling Feng's miserable cry, and hurriedly came back to his senses, pushing away the ghost elder and said: "Okay, let's talk about love and wait for the future, let's hurry up and resist this cold air, don't you see that this cold air is unusually violent?" ”

"That's right, it is estimated that there are some people with ulterior motives who want to prevent Ling Feng from advancing to the next level, no matter what, we must resist this cold air regardless of what we say today!" As the ghost elder spoke, a majestic Yin Soul power was released, and the Soul Elder next to him did not hesitate, and a force frantically killed.

In an instant, under the effect of their powerful power, the endless cold suddenly stopped the pace of the charge.

"Boy, come on and advance, even if we join forces, it is impossible to resist the extremely strong cold of this Yin River, which stretches for thousands of miles and is endless!" The ghost elder took a breath and hurriedly yelled at Ling Feng.

Ling Feng naturally heard it clearly at this moment, where did he dare to hesitate for the slightest, and at that moment he inhaled the qi of the Yin River, and in an instant, the breath of his body began to burst strongly, followed by the "Soul Suppression Purgatory Technique" that he had cultivated, and finally there were signs of a breakthrough.

"Broken!" Grasping such a once-in-a-lifetime gathering, where would Ling Feng hesitate, he shouted, and rushed to impact, with the help of the Yin River, which stretched for thousands of miles, it was like a flood rushing through the embankment in an instant, and the third weight of "Soul Suppression Purgatory" collapsed all of a sudden, and in an instant he finally stepped on the third level, this is not relying on the exchange of merit points, this is a real impact, and the power brought by such an impact is definitely much stronger than a simple exchange!

"Boy, don't patronize the kid, with your current impact, you can rush up again, seize the opportunity, rush!" The soul elder looked at Ling Feng and hesitated slightly, and hurriedly shouted.

At this moment, the powerful cold qi has been killed, the ghost old man has stopped talking, all his strength is competing with it, obviously every second of this next time is the old couple for themselves.

At this moment, Ling Feng nodded fiercely, and once again frantically impacted, the Yin River Qi in his body was wildly agitated, these Yin River Qi and the Yin Maiden's Qi in Chen Anqi's body in the world were actually the same, but these breaths were quite majestic and pure, much stronger than the Qi in Chen Anqi's body.

"Rush!" Ling Feng didn't hesitate at all, he shouted again, and the strength of the "Soul Suppression Purgatory Technique" rushed forward again, starting from the third level in an instant, his breath rose all the way, and he was vaguely about to break through the rhythm of the fourth level.

In an instant, Ling Feng was pleasantly surprised in his heart, and he broke through the two layers in a row at once, but it had never happened before, and if he rushed directly to the fifth level in one go, then the restrictions between himself and Su Qing would be easily solved!

Rush Rush!

At this moment, Ling Feng's body is extremely hot!

"Good boy, he really has extraordinary potential, hurry up and rush to the fourth level! I can't stand it anymore! The ghost elder shouted violently, and at this moment, all his body turned white, and the cold air of the Yin River hit him, which was definitely not trivial.

Ling Feng knew in his heart that if all these cold qi hit him alone, I was afraid that he would be dissipated in an instant, and the foundation building realm would also be completely destroyed.

"Fourth, break!" Ling Feng knew this very well, and he drank suddenly, and suddenly the fourth barrier loosened again.

That's great! Ling Feng was overjoyed in his heart, and at this moment, he only felt that his strength had improved by at least four or five times compared to the original.

"It's not broken now, when will it be broken, it's broken!" Ling Feng roared wildly, and almost the Yin River around him for two or three miles was boiling.

In an instant, the fourth level of "Soul Suppression Purgatory Formula" was directly blasted!

And at the moment of the fourth breakthrough, the last half-step foundation building realm was also frantically impacting, and it was completely broken through in an instant.

The supreme foundation realm, the era of immortal dao belonging to Ling Feng has come......
