In this way, after three days of hard cultivation, it was not until halfway through the third day of entering the secret room that he suddenly opened his eyes.

At this time, the Yuan Force condensed in the Ancient Primordial Dao Aperture was like an ocean, and its whole body was black, filling the Ancient Dao Aperture.

"The Dao Aperture has been expanded by me to the last moment, and what I have to do now is to rush through the Dao Aperture Wall with all my strength, as long as I break through, I will be a first-order peak cultivator. Gu Chu secretly said.

At the same time, he didn't rush to break through, but stood up and dealt with his own problems before starting to cultivate again.

"Whew, come on!" Gu Chu's eyes flashed, and then his mind sank, and all the Yuan Force in the Dao Aperture seemed to be crazy, surging towards the surrounding Dao Aperture Wall with all his strength.

Bang bang ....

The sound of waves crashing on the wall of the Dao Aperture was strangely transmitted from the Dao Aperture to Gu Chu's mind.

Generally speaking, the sound in the Dao Aperture cannot be heard by cultivators, but in the notes left by the immortals, there is a method to hear the sound in the Dao Aperture, and in ancient times, this method could also be used to make a preliminary observation of the situation of the Dao Aperture.

Of course, this approach doesn't really work, but it's much better than nothing.

Listening to the sound of the waves of Yuan Force hitting the wall of the Dao Aperture, Gu Chu closed his eyes tightly and nodded slowly.

By listening to the sound in the Dao Aperture, Gu Chu could feel that the wall of his Dao Aperture seemed to be relatively shallow, and it must be easier to break through.

"Whew...."Gu Chu took a deep breath, and his whole body was shocked: "Don't talk nonsense, let's sprint with all your might!"

As soon as the words fell, a large amount of Yuan Force in the Dao Aperture immediately went crazy again, even a few points more poignant than the previous madness.

As the waves of Yuanli slammed on the wall of the Dao Aperture, a series of violent sounds continued to resound throughout the Dao Aperture.

Bang bang .....bang

The waves transformed by Yuan Li were like crazy, and wave after wave slammed into the wall of the Dao Aperture, as if the wall of the Dao Aperture that wrapped them was their enemy, making the Yuan Li waves use all their strength.

Gu Chu also gritted his teeth, beads of sweat on his face continued to drip down, the Yuanli waves in the Dao were so crazy, it was at the cost of his energy, and the speed of energy consumption was also quite fast, just mobilizing the Yuanli waves for a moment, he was sweating profusely.

Such a crazy breakthrough lasted for a whole hour before it was completely over.

The wall of the Dao Aperture shattered in vain, and after the waves of the Yuan Force Sea poured into the new world, they continued to invade their new home, until another layer of thick Dao Aperture Wall was stopped.

But at the same time, the ancient Dao Aperture had also doubled, and now his Dao Aperture could store more Yuan Power.

"Whew, whew!"

But at the beginning of the past, there is no way to manage so much.

After three hours of hard perseverance, after the breakthrough was over, Gu Chu no longer had any strength, lying straight on the animal skin, his whole body was sore, his brain was dizzy, and it was quite difficult to even think.

"It's too hard to break through. After a long time, Gu Chu sighed.

He checked the time, and it had been two and a half days since he entered the chamber, and most of the third day had passed.

"If the allies want to reach the main part of the Luoluo Mountain Range, it will take about two weeks, if they encounter problems on the way, it may take longer, but they will definitely not return for more than a month, since this is the case, then the time for me to break through from the peak of the first order to the second order is at least fourteen days, and at most about twenty days, if I cultivate hard, such a short time will definitely not work, and I can only consume yuan stones. ”

Thinking of this, Gu Chu sighed secretly and took out a bag of Yuan Shi from his arms.

These Yuan Stones are all dark colored, and what they contain is the Soul Dao Yuan Power.

Gu Chu looked at these Yuan Stones, his mind was heavy, there were not many Soul Dao Yuan Stones in his hand before, only dozens of pieces remained, but there were a hundred Yuan Stones in this bag, and these Yuan Stones were all the inventory of the Kunlun Niu Tribe's Soul Dao Yuan Stones.

Now, there is absolutely no Soul Dao Yuan Stone in the Kunlun Niu Tribe's treasury, and even if there is, it will definitely not be as many as double digits.

Under the strong demand of the ancient beginning, the Kunlun Niu tribe almost turned over the inventory several times, and even sent someone to rummage through it at the beginning of the ancient world, and only stopped after determining that there were no more soul Dao Yuan stones in the Kunlun Niu tribe.

The reason why he took out the Yuan Stone was because the cultivator wanted to break through, and relying on the Yuan Stone to break through was also one of them.

"There are more than a hundred yuan stones, if I want to break through, there are some shortcomings. Gu Chu calculated, but still sighed: "There is no way, you can only rely on your own hard cultivation to have any hope of breaking through to a second-order cultivator within twenty days." ”

Thinking about this, Gu Chu didn't have a trace of confusion and directly began to cultivate.

From now on, he cultivates extremely hard, even if he excretes and eats, he is at an extremely fast speed, and even if he sleeps, he only guarantees that he can sleep for two hours, even if his face is not good, he has to forcibly support himself to get up and cultivate.

Also, he began to use some of the methods in the Immortal Notes, although these methods were very efficient, but all of them were difficult or painful, but Gu Chu only cared about time and effect, as long as it did not harm his health and potential, he tried them one by one.

In this way, he himself was quite miserable every day, but it was still like this, and Gu Chu also persisted for twenty days.

Twenty days later, he stepped out of the chamber again.

"In Xia Kunxu, greeting... Huh?"

Seeing the appearance of the ancient beginning, the elders of the Kunhu clan who had been waiting outside for a long time were also shocked.

The beginning of the ancient period is quite miserable now, because of the irregular work and rest these days, his originally warm and jade-like face has become withered, his eyes are full of bloodshots, his eyes are deep, his face is sallow, and his body is rickety, as if he is ten years old.

Kun Hu looked at his appearance, stared at him and looked up and down several times before he was shocked: "Lord Alliance, you... How did you become like this?"

"Hehehe... It doesn't matter how I look. Gu Chu shook his head and looked at Kunhu in front of him, but his eyes were shining: "The important thing is that my cultivation has risen." ”

"Oh, then, is your cultivation?"

"That's right, I've already become a second-order cultivator!" Gu Chu grinned, his expression excited: "A second-order cultivator can cast sixteen soul roars, even against the Ten Thousand Beast King, I can affect part of its combat power, and it is no longer as weak as before." ”

"Hahaha, besides, my greedy wolf tribe also has a cultivator who can handle it!"

Gu Chu grinned and looked happy, unconcerned about his own pale face.

Although his appearance was miserable, his heart was extremely happy, the Yuan Force in the Dao Aperture was surging in waves, and the powerful power was constantly transmitted from the Dao Aperture to Gu Chu himself, which made him very happy.
