"Senior Sister Ziyu, you shouldn't fall into the well at this time!" Yu Han couldn't help but say with a bitter face, and kept retreating.

Ziyu's cold pretty face didn't show the slightest expression, and he looked at Yu Han so calmly: "I said, you have to die!"

"But you can't cross the river and tear down the bridge! If it wasn't for me just now, you might not be able to persevere!" Yu Han waved his hand.

"If you don't seal my cultivation, I can resist it!" she approached Yu Han step by step.

Then looking at the growing fear in Yu Han's eyes, a trace of disappointment flashed in Ziyu's eyes.

Yu Han's face was already pale at the moment, and the corners of his mouth couldn't help twitching a little.

This kind of performance really made Ziyu doubt his unyielding will when he confronted the resentful spirit.

Therefore, her jade hand reached out, and the sharp sword qi at her fingertips began to stir!

"Sea of Blood—" Yu Han stretched out his hand and pointed at Ziyu's back, gasping.

Ziyu frowned and looked back, but at the same time stunned.

Behind her, it was originally the location of the blood line, but as Yu Han drank off those resentful spirits, the blood line also disappeared.

However, at this moment, what appeared in front of Ziyu's eyes was a blood-red stormy wave.

It was a sea of red, almost half of the sky, rolling and slapping in this direction.

It turned out that Yu Han's previous expression was that he saw this sea of blood, not because he was afraid of himself.

"It seems that you still can't kill me for the time being!" Yu Han muttered: "This sea of blood is very powerful, you see that the splashed seawater, along with the city walls that have not corroded for so many years, have been scorched through!"

Ziyu Dai's eyebrows frowned slightly, and sure enough, the water droplets that splashed on the ruins of the broken wall in the sea of blood directly penetrated the pieces of bluestone.

This sea of blood is unexpectedly corrosive.

If the flesh and blood of the two of them are contaminated with a trace, I am afraid that they will be melted immediately.

"Don't go yet!" Ziyu's voice sounded like waking up from a dream.

Immediately, the jade hand tightened, and it was already grabbed by Yu Han, and rushed towards the rear.

As if a tsunami had erupted, the blood-red sea was boiling and surging towards this direction, as if it was about to swallow up the entire submerged ancient city.

"That sea of blood is murderous, it doesn't belong to the original inhabitants of the ancient city, it should be the breath of Baiqi!" Ziyu shook off Yu Han's arm without a trace, and said lightly.

Yu Han didn't think about it, and nodded in agreement: "Although Bai Qi won back then, he also suffered a lot of losses, and the sea of blood should be the Desolate Emperor Army that fell here!"

"The inhabitants of the ancient city can condense their grievances, and so can those desolate emperor armies!"

Hearing this, Ziyu couldn't help but add: "And they are organized, they are very regular when they rush to kill, and in the sea of blood, it seems that there is a force controlling them, it should be the battle intent that Bai Qi sealed here!"

Ziyu looked at Yu Han's somewhat puzzled gaze, and continued: "Bai Qi is their military soul, it seems that he doesn't want these soldiers to bury their bones elsewhere, so he sealed his battle intent here, but he didn't expect that with the condensation of his war intent, those desolate emperor troops who passed away would turn into such behemoths!"

Yu Han's face couldn't help but change greatly when he heard this, and the sea of blood continued to engulf in this direction, and then he saw that the bright line composed of resentful spirits appeared again.

It's just that compared to the sea of blood, this bright line seems very small.

The two forces collided with each other in one place.

The seemingly inconspicuous bright line stubbornly resisted the erosion of the sea of blood and prevented it from continuing to erode.

"Burn my body and protect my city!"

A loud voice sounded, like a mournful war song of doomsday twilight!

"Let's get out of here!" the two of them quickly fled into the distance, clearly sensing that the wraith would never be a match for the Sea of Blood.

So they have to find a safe place as soon as possible!

At the same time, Yu Han also had a trace of unbearability in his heart, it must have been when he confronted the resentful spirit at the right time, and that breath aroused the sleeping white fighting intent.

Then it turned into a sea of blood, and he wanted to inherit his last wish and raze this ancient city to the ground!

"Here, maybe you can't escape!" Ziyu sighed slightly, all around him was the scope of the ancient city, and the sea of blood was bound to submerge here.

So the two of them shouldn't be able to get out!

Yu Han was just about to speak, but his eyes suddenly lit up, and at the same time, a smile on the corner of his mouth outlined: "Not necessarily, let's go to the front and have a look!"

There is an ancient building in front of it, which has collapsed in half, and the surrounding stone walls are also covered with traces of being killed.

However, compared to those ruined towers, it is much more complete!

The reason why Yu Han was surprised when he saw this ancient building was not because it was complete, but because the stone wall of this ancient building was carved with a mysterious texture.

That's a pattern.

Outside the ancient building, a formation was depicted!

While thinking about it, the two figures had already landed at the door of the ancient building.

The vermilion gate had dimmed too much, and the door panels had cracked densely with cracks, and the corrosion was also very serious.

However, this ancient city has been buried here for so long that even the stone walls are a little weathered.

The wood used to build the houses has long since turned into fly ash and no longer exists.

And this gate is still there, which shows the extraordinary nature of this formation.

Yu Han glanced back at the resentful spirit Changhe, who had been suppressed by the sea of blood, and frowned: "This ancient building was once supposed to be a heavy place, so it was laid out in a formation!"

"Formation?" Ziyu suddenly remembered that Yu Han had used the formation to deal with him, and immediately believed a little.

"Not bad!" Yu Han nodded: "It's just that this formation is very powerful, with my current formation level, I may not be able to activate it, and the odds are not great!"

"I'm going to give it a try!" Ziyu's words were very succinct, and she seemed very reluctant to talk nonsense.

Yu Han glanced at her and sighed slightly: "We will enter it, but once there are unpredictable changes, we must leave immediately!"

"I can't escape!" Ziyu said.

Yu Han looked at her delicate face deeply: "You can't die!"

"Nothing to be afraid of!" Ziyu said calmly.

Yu Han suddenly remembered the breath of relief that came out of Ziyu's eyes when he was killing the Shengtang and when the blood cloud covered his body.

Maybe she's been through something unusual!

However, this is not the time to ask too much, Yu Han's mind is immersed in the lines on the stone wall.

This time, Ziyu surprisingly didn't bother Yu Han, Meimu looked around, and the jade hand pressed lightly on the wooden door!

The wooden door opened, but it collapsed with a bang!

This wooden door, which I don't know how long it has existed, collapsed under the gentle push of Ziyu!

Yu Han was also taken aback, and couldn't help but roll his eyes: "Senior Sister Ziyu, aren't we naughty?"

Ziyu's expression was also a little embarrassed, but it was quickly covered up: "I didn't know it would be like this!"

"Huh, here, it seems to be a Dan room!" Yu Han suddenly said in surprise.

With the collapse of the two gates, the situation inside the ancient building is unobstructed.

This is an ancient building with only one floor, with an area of only about 20 zhang.

What appeared in front of them at this moment was a huge Dan furnace, and there were many wooden lattices around it, all of which had fallen to the ground, and some had even been damaged.

"It seems that here, there is no escape from the fate of being ransacked!" Yu Han shook his head.

"The White Emperor Army, take everything here with you!" Ziyu added.

Yu Han stretched out his hand and pointed to the Dan furnace and said, "But they forgot to take this Dan furnace away!"

Hearing this, Ziyu couldn't help but look at the Dan furnace, a huge Dan furnace made of bronze, which was already rusty at the moment, and the two furnace ears had also corroded, and it was even covered with cracks.

She didn't ask, but her eyes kept looking.

Yu Han knew that she seemed embarrassed to ask herself, so she said to herself: "The formation outside the ancient building, its array is on this Dan furnace!"

As the words fell, he stretched out his hand and pointed to a gossip pattern on the surface of the Dan furnace.

Although it is blurry at the moment, it can be clearly felt that the surrounding textures are like a sea of rivers, and finally all converge here.

"You want to try it?" Ziyu began.

Yu Han nodded: "This formation should be able to reach the fourth level, and now, I am only a first-level formation master, not even a second-level formation!"

The subfish did not have an opening.

Yu Han took a deep breath, his eyes flickered, and said, "But you're right, you have to give it a try!"

His gaze turned into two sword rays and landed on the gossip pattern!

Analyzing textures.

It may be difficult to arrange the formation, especially if you need the support of the Dao pattern, which is very strict, how many Dao Patterns can lay out the corresponding level of formation.

If you want to rely on the Shaodao pattern to arrange a high-level formation, it is a complete dream.

It's a means that you can't cheat.

But at this moment, what Yu Han had to do was not to arrange the formation, but to find the broken place of the formation and repair it.

In this way, it is a lot simpler.

The dao lines in his body are bulging, and forty-six dao lines are coiled around his body.

Fortunately, because of the resentful spirit's heart-to-heart, the Five Hells Mind Contemplation Technique has improved, and at the same time, it has led to an increase of eighteen Dao patterns, otherwise he would not have the confidence to waste time here at this moment!

"This formation is called the Bagua Spirit Wheel Array!" a name came to Yu Han's mind.

Then, with this gossip as the center, the surrounding textures spread out in all directions.

"Poof—"

Yu Han opened his mouth and spurted out a large mouthful of blood, and his face turned a little pale.

However, there was a bit of surprise in his eyes.

"I see, I understand!" In Ziyu's puzzled gaze, Yu Han wiped the blood from the corner of his mouth.

Ten fingers kept beating, and the lines were intertwined in front of him, forming a dense combination, which was imprinted on the gossip!

"Hum—"

The dilapidated Dan furnace, which was originally like a dead thing, suddenly shone brightly.

The bright light surged all over the sky, forming a terrifying qi machine, which swept backwards.

At the same time, the entire ancient building lit up, as if a light had been lit.

"It worked!" Yu Han breathed a sigh of relief, and a smile cracked into the corner of his mouth.

Just, right now!

"Click!"

A crisp sound came, and at the bottom of the Dan furnace, a crack opened, and then the golden light that had just risen collapsed in an instant!

"Boom—"

In the distance, the terrifying sea of blood vibrated wildly, finally defeating the resistance of the resentful spirit, and crushed madly towards this side!
