In the melodious roar of the dragon, the dark clouds stacked downwards like cotton wool, and the air pressure became extremely low, and if a mortal were here, he would die of lack of oxygen in a quarter of an hour.

Not only has the oxygen become thinner, but even the aura has become thinner.

When the ice fog cleared, the surroundings were unobstructed - the landscape here was different from before, the obelisk-like icicle forest occupied a large area, and in the "forest" there was a frozen lake of several hundred square kilometers, the ice in the lake was turquoise, and several huge wheel-shaped ice bodies were frozen on it, like the stern of an ice and snow ship sinking into the lake, and the bow of the ship was frozen after the lake surface.

The dragon's groaning suddenly stopped, and the hailstones the size of the desks smashed down overwhelmingly.

Zhang Ning's black and white board hung above his head, bearing the terrible impact. Zhang Ning injected the pure spiritual power into the black and white board, and the upward white side suddenly burst into a strong light, and at the moment when the giant hail was about to impact, an upward spiritual aura field was generated, and the hail was blocked by it, and the impact force on the black and white board was much smaller, and the pressure dropped sharply.

Another dragon groan followed.

Countless snowflakes with razor-sharp edges swirled in from all directions, each the size of a rebound. The snowflakes are extremely fast and in awkward positions, as if they have calculated the direction and speed, and do not interfere with the huge hailstones that are constantly falling above.

Zhang Ning also departed a part of the spiritual power to inject it into the shutter armor, and sacrificed the golden gear that had been restored to its original state, blocking and shattering the approaching snowflakes.

Above him was the "bang" sound of a giant hail hitting a black and white board, and around him was the "clang" sound of golden gears shattering snowflakes and the sharp "boom" grinding sound of sawn steel plates made by leaking snowflakes cutting through shutter armor.

After a stalemate like this for a quarter of an hour, one-third of the spiritual liquid in Zhang Ning's blue and white porcelain vase was consumed, which made Zhang Ning's flesh painful.

Immediately, another sharper, shorter dragon moan rang out.

The sound of the wind suddenly turned into a scream, and the heavy clouds began to rotate, and in a few breaths, the clouds on Zhang Ning's head disappeared, and he saw the round sky above his head, which was dazzlingly blue. Beyond the circular area of one square kilometer of his body were giant swirling clouds.

The temperature fell off a cliff, and pale blue snowflakes drifted around.

Zhang Ning had watched movies and studied chemistry, so he knew that this was when the temperature was extremely low, and both oxygen and nitrogen had become solid.

He understood the reason, but his cultivated body couldn't accept this sudden extreme low temperature. This may be the low temperature that even the monks cannot bear.

Zhang Ning did not hesitate to hit the plastic lighter.

The colorless flames, once warm as spring, instantly ignited the pale blue snowflakes fluttering around.

Zhang Ning immediately took the opportunity to hide in the Qiankun treasure snail.

There was a loud bang.

The deflagration only lasted for three breaths, and after that, Zhang Ning's once foothold was the center, and a radius of thousands of miles turned into a sea of fire.

Zhang Ning ignored the colorless flames around him, rushed out of the Qiankun Treasure Snail, and dragged the seriously injured and broken ice dragon into the Qiankun Treasure Snail with double-sided tape.

Looking at the loot, the sense of satisfaction and accomplishment in Zhang Ning's heart was much stronger than that of clearing a large-scale game.

Whether or not he can obtain the ice crystal essence determines whether his cultivation will stop at the Yuan Infant stage. And after several inferences, he firmly believed that this ice crystal essence was going to fall on the ice dragon, and it was in vain that he exhausted a large amount of spiritual fluid and fought hard, and finally took the ice dragon into his pocket.

The hard battle just now consumed a lot of spiritual power, and Zhang Ning's spiritual energy in his body was now running chaotically, and after he sealed the ice dragon, he went to sit and breathe.

After four hours, the pranayama is complete. When Zhang Ning was ready to devote himself to the great cause of pumping the dragon marrow with full enthusiasm and vigorous spiritual power, the ice dragon was gone!

Zhang Ning jumped to the front of the seal and removed the talisman and the array chess.

All that remained of the white earth was a puddle of water.

Melted?!Roasted by the Dongming Xuanhuo?!

Zhang Ning hurriedly pumped water from the white sand to distinguish it - it was indeed ice and snow meltwater.

He used his mind to continue to probe the place where the ice dragon once resided—there was indeed only a puddle of frozen meltwater.

Zhang Ning was depressed, could it be that the capture posture was wrong?...... Could it be that you can't use a weapon of mass destruction like the Cave Xuanhuo, but should subdue the dragon with virtue, make it happy and convinced, bow down, tie its claws and capture, and draw the dragon marrow by itself?

Maybe the problem appeared in those four hours, maybe after the capture was successful, the pith should be extracted immediately, so the shelf life of the ice dragon is less than 8 hours!

He continued to pranayama unwillingly, but his mind was restless and he could not enter the state.

The fire outside burned for a whole day and a night.

When the fire weakened, Zhang Ning left the Qiankun Baoshao, this ice dragon was wasted, and he had to continue to search for it north.

The place where the ice dragon once inhabited was unrecognizable - the obelisk of the icicle jungle burned down to its roots, and the frozen lake boiled and dried up, leaving only a black pit. Zhang Ning speculated that the snow and ice here were not all made of water condensation, and perhaps solid oxygen......

After Zhang Ning scanned it with his divine sense, he was disappointed to find that there was nothing valuable here, so he had to step on the paper tray and continue to fly north.

......

In the Qiankun Treasure Snail, the water melted by the ice dragon was seeping into the white soil extremely slowly, flowing in the direction of the spiritual spring.
