(It's the last day of this month, ask for a monthly pass~~ I hope to get a top ten)

......

I saw a flash of gold, and a line of inscription runes composed of tiny runes walked around like streamers.

The energy touched the Eye of Judgment, stirring up an aftermath around it, and it galloped downward. After passing through the three-story altar, a pillar of light was formed, reaching the central core of the Heavenly Palace City.

Whoosh......

The core is round, originally one side of the body, but now it looks only the size of a fist, and the golden round body surface is full of edges and corners, and after the infusion of energy, it rotates rapidly.

As the rotational energy was thrown back, the core slowly grew, and in a few breaths it was already the size of a bowl. And the volatile energy became more and more intense, filling the entire core area, and the wisps of energy spread quickly along the protective wall of the entire Heavenly Palace City, shaped like frosty ice.

Bang Bang ......

The sound of cracking ice echoed through the temple, and the scattered energy gathered in the dome, forming a fluorescent cloud of energy, reflecting the surroundings as if it were day.

Rumble!

Suddenly, the energy mass burst out, and a dull sound was heard, causing the Heavenly Palace City to tremble, and the dazzling light forced the group to close their eyes.

Under the aftermath of the energy, Chen Mo was thrown out of the altar for several weeks. landed and took a few steps back before he stabilized himself.

Quietly, a qiē returned to peace.

Chen Mo slowly opened his eyes, and his eyes suddenly brightened.

At that moment of trembling, the structure of the entire Heavenly Palace City remained unchanged. But the space has tripled.

Even the altar beneath his feet was much more spacious, and the statues of the four angels holding the altar were painted with a layer of light. The black body surface is glowing, and the height has reached more than ten zhang.

The dome, which had just felt dim, was now glowing with fluorescent and shimmering.

"Congratulations to the master, the level of the Heavenly Palace City has been upgraded to the first level, which can travel through the sky, and the speed can reach up to 1,000 miles per hour. The structure of absorbing the aura of heaven and earth has been completed, and it cannot be used for the time being. The artillery fire range is one mile and can be attacked at any time. The cooldown time is a quarter of an hour. The machine spirit said.

Chen Mo waved his black robe and turned around suddenly, the number of reports from the machine spirit made him a little incredulous, and when he didn't restore the first rank, the big ruling cannon blasted out. Up to tens of thousands of miles. Today, the gap is a world of difference.

"I'm not satisfied with such a number. "After exhausting more than a thousand spirit stones, but only these achievements, Chen Mo was a little disappointed.

"Master, every time you are promoted to the Heavenly Palace City, the number of each item will increase tenfold, if you want to reach a higher level, the most direct way is to use the resources to choose to continue to upgrade. ”

"Go ahead and upgrade?"

"Yes. Because this Heavenly Palace City is inherited from the God of Light, the physical structure has been formed. The only thing that needs to be done is to rely on various resources to stimulate various functions and make them maximize their effectiveness. ”

Chen Mo secretly calculated to himself, when he was promoted to the first level, he would need one thousand and twenty spirit stones, so if he was promoted to the second level, it was estimated that this number would be far from satisfying. The spirit stones on his body are now counted as nothing more than two thousand five hundred.

"If that's the case, then you should know what I want to do. "I have already received this Heavenly Palace City, so I just don't care about it too much, Chen Mo secretly decided.

"Since the master has a heart, I should do my best. To be promoted to the second level of Heavenly Palace City, it requires three units of Spirit Stones, as well as zero five units of Flame Crystals. ”

Flame Crystal?

"Haha......" Chen Mo laughed loudly.

continued: "Three units of spirit stones should be three thousand and seventy-two spirit stones, and I have a lot of difference here, but this flame crystal ....... Chen Mo wanted to speak and stopped.

Helian Huowu took a step forward, took off the storage ring on his jade finger, and said, "Second brother, don't forget that there is me, there are two thousand spirit stones here, you can use them." ”

Chen Mo glanced at her, and now it seems that there is really no other way than to borrow it temporarily.

Then he said: "Wu'er, when the second brother borrowed you, he will pay it back twice." ”

"Take it, who wants you to pay it back. Helian Huo said.

"Master, as far as I know, when the last God of Light first cultivated the Heavenly Palace City, he created a cave in this underground magma layer to refine flame crystal, but the specific location cannot be confirmed, if the master is lucky, he can find this crystal mine. The machine spirit said.

"Huh. ”

Chen Mo and Helian Huowu looked at each other and smiled, only then did they understand.

No wonder when I came, I came across a cave full of flame crystals in the underground rock formation, and it was still strange at the time, it turned out to be built by the God of Light in order to upgrade the city of Heavenly Palace.

Chen Mo said: "Instrument spirit, if you have a flame spirit stone, can you upgrade it?"

"Back to the master, the energy in the flame spar is far stronger than the usual spirit stone energy, it is many times stronger, and it is not easy to control when refining, naturally, even if you have the flame spar and enough spirit stones, it is only the foundation, whether the refining can be successful and the city of Tiangong can be upgraded, it depends entirely on the master's own control ability. The machine spirit replied.

Chen Mo thought for a while, and then continued: "You don't have to worry about this matter, I want to ask you, can the current Heavenly Palace City be activated?"

"Although the Heavenly Palace City is only a level, it can be activated completely, and the master can rely on the divine thoughts as a guide to move towards the destination. ”

"Okay, activate the Heavenly Palace City and get ready to go. ”

Airplanes~

With Chen Mo's order, a buzzing sounded on it, and it was fleeting. The golden core emitted countless rays of energy, covering the entire Heavenly Palace City like a streamer.

Just in front of Chen Mo, a silver light suddenly flashed, and a transparent window composed of energy appeared, and the magma rolling and flowing in front of him could be clearly seen.

Almost at the same time, a phantom geographical map emerged, showing the intricate cave route of the entire underground rock layer.

Chen Mo's gaze froze, and his divine thoughts tapped lightly. Induced by this, the surface is immediately zoomed in. Rough lava flows, and blackstone roads that collapse in mid-air. Passed through a glittering cavern.

"Wu'er, if I didn't guess wrong, this should be the Flame Crystal Cave, right?" Chen Mo asked, staring at the geographical map.

Helian Huowu took a closer look. replied: "Second brother, there are not only flame crystals here, but also ......"

"Red spirit rat?" asked Chen Mo without raising his head.

This flame crystal cave is the place where the two of them passed when they came to the City of Heavenly Palace.

After pondering for a moment, he continued: "You don't have to worry, you can just try the power of the Great Judgment Cannon with only a first-level function, and those one thousand and twenty-four spirit stones can't be consumed in vain." ”

Looking at Chen Mo's solemn expression, Helian Huowu suddenly felt like a different person. A powerful sense of majesty loomed in him unconsciously, full of the ability that a mature man should control.

The corners of Helian Huowu's mouth hooked up a smile, there is a second brother in everything. Not a single qiē is worth fearing.

Sou~

The city of Heavenly Palace floated in place, bent in the air, and along the flowing magma river, it was shaped like a ball of light upstream.

It is hundreds of miles away from the origin of the City of Heavenly Palace. It is still the upper reaches of the river where the magma flows. The magma galloping like thousands of horses tumbled forward.

Above the lava flow, a black stone pavement that collapsed and only remained in ruins, standing in the air, extending with no end at one end, and a black but glowing golden cavern at the other.

The two bowl-sized golden spots in the cave swayed from side to side, slowly retreating. Slowly disappearing.

The spark is like a prairie fire, with more golden highlights than the smaller. It was the size of a fist, and it also shook from side to side and retreated.

Only the flame spar glowing with golden glow was left behind, which was set in the cave.

Yiqiē seemed dead silent, only the tumbling magma stream was still "roaring".

Gollum......

Suddenly, a tumbling "wave" protruded from the magma flow, gradually convexing, revealing a silvery-white air cover.

When the magma flowed down, a circular hole was silently opened at the top of the air hood.

Suddenly, two figures, one red and one black, flew out of it, jumped over the scorching magma flow, and landed on the side of the cave.

Whoa......

A burst of rubble scattered and fell into the lava flow.

"Dance, be careful. ”

Chen Mo grabbed Helian Huowu's arm, looked at the Heavenly Palace City hidden in the magma, and reminded in a low voice.

If you can get the flame crystal without a fight this time, it will save you a lot of trouble.

Chen Mo patted Helian Huowu, looked at the cave on the top, his eyes froze, and he jumped up and landed at the mouth of the cave.

Shen Nian swept in front of him, feeling the guarding red spirit retreat before he straightened his waist. Immediately after, Helian Fire Dance also arrived at the entrance of the cave.

The two glanced at each other, and the Xuangang who protected the body suddenly lingered on the surface of the body.

"Wu'er, I'm in charge of the flame hedron on the left side of the cave, and you are in charge of collecting the right side. Chen Mo said.

Helian Huowu slightly nodded his head, and the Xuangang of the two people protected the body was condensed in the palm of his hand, and the palm of his hand was around the body in front of him, forming a layer of energy, and as he pushed forward, the strength suddenly increased, covering almost the entire cave.

"Second brother, is it okay?" asked Helian Huowu.

Chen Mo held his breath and nodded, and the two of them said at the same time: "Burst!"

Bang bang......

Covered with energy, a series of explosions sounded in the cave, accompanied by the explosion of rubble, and thousands of flame crystals embedded in the rock wall flew into the air.

This sound shook the entire cavern, completely breaking the silence.

Seeing that the flame spar was detached, wisps of divine thought rose in Chen Mo's sea of consciousness, and when the overwhelming spar had not yet landed, the coefficient was wrapped in divine thought, and it was steadily suspended in the air.

One by one, the flame crystals glowing with golden light seemed to be being pulled and floated towards the two of them in an orderly manner.

Chen Mo's palms overlapped up and down, his arms suddenly opened, and a spatial ring was suspended in front of him, flashing a fluorescence, and his savings mouth was wide open.

Suddenly, the flame crystals were like undisemboweled, making a swishing sound and submerged into it.

Da Da ......

"Second brother, the red spirit rat was alarmed. Helian Huo said.
