The Jewel of Time and Space is definitely a strategic material for a city-level camp, and it is a necessary item for upgrading the teleportation array, which can increase the number of people teleported by the teleportation array at one time, and shorten the cooldown time between each teleportation; When Xu Feng left the Heavenly God Garden, he had encountered such a treasure, but unfortunately he didn't have a chance to take it;

Usually, Xu Feng also instructed Li Min to collect such treasures, and in the city warehouse, there are more than thirty pearls of time and space lying quietly, and the altar in the center of the city can be opened at any time, but because Xu Feng's own strength is insufficient, he does not dare to open it rashly;

Now that the Qingteng Demon King took the initiative to open the altar, Xu Feng was naturally able to save a little bit, and the thirteen Pearls of Time and Space were also a lot of expenses;

……

Three days later, Xu Feng arranged some matters in the City of Sacrifice, and walked towards a large hall in the center of the city with the Qingteng Demon King;

The altar in the center of the city of sacrifice is a very special building, no matter how the city is built, the altar will always be in the center of the city, and will automatically move its position with the construction of the city, which is very magical;

Outside the altar, Xu Feng ordered the construction of a large hall, with no windows around it and only a small door for entry and exit, and many NPC guards were arranged around the hall to prevent others from trespassing;

This is the forbidden place of the city of sacrifice, and many people pass by and bypass it from afar;

"I didn't expect you to be quite thoughtful about protecting the altar." The Qingteng Demon King sneered. Originally, she wanted to secretly open the altar, but she didn't expect Xu Feng to protect the altar too well, once she broke through, it would touch the city's countermeasure mechanism, although she was an eight-star powerhouse, but in the face of a city's heritage, she still didn't dare to act without permission;

Xu Feng pretended not to hear the ridicule in the words of the Qingteng Demon King, smiled slightly, and pushed open the small door of the main hall.

Although this door looks small, but the amount of blood alone, it exceeds 300,000, which is comparable to the city wall, if it is not opened by the city lord himself, even with the strength of the Qingteng Demon King, I am afraid it will take more than half an hour to break open;

Entering the main hall, a dilapidated altar, sitting alone in the center of the main hall, the gray-white rock is full of cracks, and the complex magic patterns are depicted on it, full of the vicissitudes of history and the sense of heaviness;

"This is it." Xu Feng looked up at the altar and sighed in his heart, he had seen with his own eyes that the world opposite, like slug-like monsters, swarmed out of the teleportation light door, their bodies were like a mass of plasticine, even if they were cut into two pieces, they could fuse with each other, like immortal bodies;

Those monsters, like a green torrent, directly occupied the sacrificial village, using it as a stronghold, and continued to invade towards the Blackwater Lake and the Blackwater Swamp;

"Let's get started." The Green Vine Demon King took a deep breath, took out a milky white bead, and pressed it into the inlaid hole exposed around the base of the altar;

Click~

With a soft sound, the pearl of time and space was in place, and a faint power of time and space emanated from the altar, and on the gray-white rock pedestal, the magic lines gradually brightened, and the entire altar seemed to be waking up from its slumber;

Click, click, click~

The Qingteng Demon King quickly inlaid all the thirteen pearls of time and space, and then quickly pushed them away, standing beside Xu Feng, waiting quietly;

"Do you want to enter the other world with me?" The Qingteng Demon King smiled charmingly, turned sideways slightly, and whispered in Xu Feng's ear;

"Maybe, maybe not, who knows?" Xu Feng shrugged his shoulders and said indifferently;

The two are not companions, if the Qingteng Demon King knew that Xu Feng had also entered, he might have deliberately targeted him;

"The speed of time between the two worlds is not the same, if you get late, you may not get anything!" The Qingteng Demon King exhaled like an orchid, like a tender little hand, constantly kneading Xu Feng's ears, making Xu Feng feel numb;

"My strength is still too low, and it's too dangerous to enter now." Xu Feng said expressionlessly;

"If you enter with me, you can save thirteen Pearls of Time and Space!" The Qingteng Demon King was almost lying on Xu Feng's body, and a charm emanated from her;

Hiss~

The golden light, like a tentacle, continued to climb up along the magic lines on the altar, and finally condensed on the altar at the apex of the altar, and the golden light became brighter and brighter, gradually condensing into a sphere;

"Ready, the space-time passage is about to be established...... Xu Feng said in a low voice;

Seeing Xu Feng's expressionless face, the Qingteng Demon King's eyes showed a trace of doubt, could it be that this guy really didn't want to enter the opposite world with her?

The golden light became more and more abundant, and as the formation was activated, the golden ball of light on the altar slowly stretched up and down to the upper and lower sides, and began to narrow, cracking a blood-red eye-shaped crack in the center;

Airplanes~

With a soft sound, the portal completely stabilized, and on the high altar, there was a blood-red light curtain more than one person high, with a black bead in the center, surrounded by a golden border, constantly emitting silky energy;

"Are you really not going to come in with me?" The Qingteng Demon King didn't seem to give up, turned his head and stared at Xu Feng's eyes and asked;

"Once the teleportation channel is stabilized, you only have three minutes to enter, and the later you go, the greater the chance of being swept away by the space-time turbulence." A smile appeared at the corner of Xu Feng's mouth, staring at the Qingteng Demon King and whispering;

"It's boring, then I'll go alone." The Qingteng Demon King seemed to be sure that Xu Feng was really unwilling to enter the teleportation array with her, and ran towards the altar quickly;

The high altar has more than a dozen steps, and when it comes to the altar, the Green Vine Demon King is about to dodge into the portal, but is bounced out by a mysterious force;

"Sacrifice~" An angry voice echoed across the altar;

The Qingteng Demon King was stunned for a moment, then glanced back at Xu Feng, with an angry look in his eyes, he bit his silver teeth and took out a gold-quality piece of equipment from the package;

"Not enough~" The angry voice seemed to become louder, and even the portal began to shake slightly and became unstable;

The Qingteng Demon King gritted his teeth and immediately took out more than a dozen pieces of high-quality equipment from the package;

All the equipment was sucked into the light curtain, and after a while, there was a chewing sound of "click~" in the light curtain, and soon, a comfortable burping sound sounded, and the teleportation light curtain became stable again;

"Humph!" The Qingteng Demon King snorted coldly, took out a jade statue of emerald green in his hand, held it tightly, and rushed towards the light curtain;

When the figure of the Qingteng Demon King completely disappeared into the blood-red light curtain, Xu Feng jumped violently, clenched the deception crystal in his hand, and rushed towards the blood-red light curtain like lightning, and suddenly, Xu Feng's whole person was wrapped in a purple light, flew into the light curtain, and disappeared in a blink of an eye.

At the moment when Xu Feng disappeared, the ripples on the light curtain seemed to stagnate, and then an angry voice echoed in the hall: "Sacrifices, no sacrifices~~"

Bang~

With a loud bang, the entire light curtain suddenly shattered like a mirror, and all the inlaid beads of time and space exploded at the same time and turned into powder, and suddenly a white mist enveloped the entire altar, and it took a long time before it gradually subsided;
