The sky is getting darker and darker, Li Yi and the others are also nervous, even Silkworm Tianqi is a little nervous, after all, whether Li Yi and Zixuan can escape this catastrophe this time is all on him, and he can't afford to make the slightest mistake.

In front of the Yin God, even if it is just a small mistake, I am afraid that it will be the price of life.

Li Yi and the others came to the front of the Yin Qi barrier early, and here they could see a city standing in front of them from a distance, with a vast geographical area, and the city wall rising from the ground, like a giant dragon lying around, as if there was a tendency to despise the world, which made people daunting.

Isn't that the Imperial City of Qin!

"Qin Yao, we'll be able to meet soon. Li Yi silently stared at the city in front of him, and he often remembered the good times in the place where he served.

"Li Yi, why do you have to go to this city?" Zi Xuan found that Li Yi was staring at the city in front of him, and was a little puzzled.

"Visiting a friend!"

"I didn't expect him to be quite righteous, and he traveled thousands of miles just to find friends. At this moment, for some reason, Zi Xuan seemed to be looking forward to meeting this person, she wanted to see what kind of sacredness it was, which actually made Li Yi so concerned.

There was still a world before it got dark, and Li Yi no longer looked at the Imperial City of Qin, but took up the method of building a foundation and cultivated.

When Li Yi finished running for a big week, all the innate qi in his body was stripped out of his body, and at this moment, he felt as if something was missing from his body, and then the innate qi surged to his lower abdomen.

As a result of the mind, the dantian in the lower abdomen has been formed, and it is like a spherical nebula, suspended there, like a dream, and the innate qi is floating around this nebula.

If it was before, the innate qi would soon automatically return to the body, but this time it was a little different, the innate qi seemed to have lost its roots, and it couldn't find a way back, and it kept wandering around the nebula.

Li Yi knew that with the help of Bai Dan, after these days of cultivation, he had finally taken the last step to open up the dantian.

In this step, it is necessary to fuse the innate qi with the formed nebula, and when the two are completely fused, Li Yi will become a veritable foundation building monk.

However, this process of integration cannot be disturbed, once the foundation building of the 100-day foundation reaches this point, then this person will definitely forge the true foundation, but this step is very critical, and it must not be stopped halfway, otherwise the previous efforts will be wasted.

No one knows how long the integration will last, some in less than an hour, while others in a few days, or even a month.

Often, when the last step of the monk's 100-day foundation building is approaching, he will find a hidden place, but Li Yi has always been groping by himself, which led to the current situation.

Seeing that the sky was about to completely darken, Zixuan saw that Li Yi had not yet woken up from his cultivation, and was a little anxious, and was about to forcibly wake him up, but was stopped by Silkworm Tianqi on the side.

"Should he be in the last step of building the foundation, or should he wait a little longer......"

"Li Yi is really, at this juncture, he is still an outer disciple of Qi Tianzong, doesn't anyone tell him that the last step of building a foundation is very important?" Zi Xuan moved back and forth, looking puffed out.

Silkworm Tianqi on the side couldn't help but cough a few times.

"Alas, Uncle Tianqi, I didn't mean you, although you are the founding patriarch of Qi Tianzong, but it was all many years ago, I'm afraid no one remembers it now, not to mention that you just accepted Li Yi as an apprentice, it has nothing to do with you......!

Silkworm Tianqi looked at Li Yi, he didn't expect this son's comprehension to be so amazing, but he didn't know the common sense of these cultivation realms.

"Not good!" Silkworm Tianqi sensed something strange on the top of the mountain, and this time the sky was not completely dark, and there were signs of the ghost gate opening......

And Li Yi has also reached the critical moment of building the foundation, but at this time, it is important to protect his life first, Silkworm Tianqi finally decided to interrupt Li Yi, but just as he was about to wake up Li Yi, Li Yi's eyes suddenly opened, and a ray of essence flashed.

"Top-grade dantian!"

Silkworm Tianqi swept slightly, and knew that Li Yi had successfully built the foundation, so he didn't have to think about it in a hurry, he immediately said: "The ghost door is about to open, hurry up and ......"

Li Yi nodded when he heard this, and without delay, he immediately picked up the Heavenly Law Hidden Mantra, everything was relatively smooth, and the three of them completely disappeared in shape and breath, and returned to the void and desolation.

"Squeak!"

At the top of the Qinling Mountains, the heavy gate slowly opened, and with the opening of the portal, a trace of black mist floated out from the crack in the door, revealing a gloomy and weird atmosphere, which made people shudder.

The three blood-colored characters of 'Ghost Gate' seem to be alive at this moment, and the glow is flashing, and the blood is dripping...... The carved patterns on both sides flash through the brilliance of the road and appear lifelike.

A dull, mournful voice came from the portal, like a demon howling, and it was like a demon crying......

Finally, I heard a "swaying" sound of the door opening, and when I looked at it, the black fog inside the portal was filled, like an abyss demon cave, and I couldn't see my five fingers.

Suddenly, in the black mist, a dazzling light flashed, like a dazzling star, getting brighter and brighter. Under the bright light, the outlines of two divine weapons could be vaguely seen, which were the two weapons carved on the twin peaks, an iron fork and a spear.

The two divine weapons were like the dawn of the sun, showing inch by inch from the portal, and with a "dang" sound, they finally fell on the top of the Qinling Mountains.

The divine soldier touched the ground, and Qin Ling kept shaking, as if it was about to collapse, and many people in the prison city discovered this strange situation, and they all cast their eyes here.

Then the black fog surrounding the divine weapons dissipated, and at this moment, it was discovered that the two divine weapons were actually held in the hands of others, who could hold such divine weapons in their hands.

That's right, he is the two Yin Gods in charge of the Ghost Gate, one with a bull-headed body and the other with a horse-faced body! Although the carvings on the twin peaks are already quite powerful, they are far from the real body compared to the real body.

The bull's nose spewed out a breath, and after this breath, all the vegetation withered and turned into nothing, leaving only a pitch-black land.

"Old Niu, why are you still so angry?"

"Hmph! This bird errand, we have been doing this since I can remember, and now we are not what we used to be, and we still let me ......"

"Shhh......hh If these words reach the mouth of the Fifth Hall Master, we will be miserable! Let's do the right thing, anyway, it will be this time in ten days. ”

The bull-headed yin god snorted angrily, and then raised the iron fork in his hand and waved it at the sky, and with this swing, the yin qi barrier that enveloped Qinling instantly burst open.

Li Yi, who was hiding in the void and desolation, clearly felt that the yin qi barrier had disappeared.

"Let's get started, old cow!"

The bull-headed yin god nodded, and then raised the iron fork, and the horse-faced yin god then raised the spear in his hand, and with a "ding" sound, the iron fork and the spear collided together, and the bull head and horse face had words in their mouths.

After half a sound, he shouted at the same time: "Conjuring spirits!" The sound was like muffled thunder, and the Tao was shocking.

As soon as these words fell, from the intersection of iron forks and spears, a pitch-black banner instantly appeared, with extremely complex patterns on it.
