With the system, I take advantage of the heavens and the world

Broken Cloud City emits a soft white light, resisting the raging wind outside.

But it is also unstable, and it seems that the city will be destroyed at any time.

As time passed, the white light outside the city became dimmer and dimmer, and finally disappeared, and the strong wind directly blew on the city wall itself.

The city wall was rubbed with sparks, and the temperature gradually increased.

Some cloud bricks could not bear the pressure, broke away from the city wall, and were swept away by the strong wind.

The city wall that was originally integrated has a loophole.

Immediately afterwards, more cloud bricks were swept away, and the wind demon entered the city, rampaging recklessly.

Countless people, objects, and buildings were swept away and destroyed.

Tang Bihai had already set up a defensive circle around his residence, and successfully survived the catastrophe.

After the wind demon passed, everyone found that the part of the city wall that Tang Bihai was in charge of building was intact.

The refined cloud bricks were placed on the city wall properly.

Everyone immediately understood that Tang Bihai was a master of formations, and the formations he designed could completely resist the wind demons.

This is too important for Yunren.

Tang Bihai was invited to the City Lord's Mansion for a grand reception.

The city lord personally received him, and asked him to help design the entire city's defense array.

Tang Bihai agreed without hesitation, and took the opportunity to make a request to ask the City Lord's Mansion to help find the Nine Deaths Resurrection Grass.

The city owner agreed on the spot and promised to pass on his request.

The cities in the cloud world are naturally connected.

Soon, other places knew about it and helped to find the Nine Dead Resurrection Grass.

Since then, Tang Bihai has stayed in Yunzhongjie, helping the city lord build a large formation to protect the city, while waiting for news.

But on the 439th battlefield, Tang Ming had successfully completed the task of the Death Squad and returned to the White Tiger Army.

However, he did not return to the original battlefield, but stayed at No. 439 battlefield, still on the patrol of the White Tiger Legion.

Now, his pressure is much lighter and he has more free time.

He decided to raise the ground fire furnace as soon as possible.

During this period of time, after continuous refining of the avatar, the earth fire furnace is only one step away from entering the magic weapon level.

The patrol mission here is similar to the original one, and after a mission, there is a long rest period.

Taking advantage of the rest time, Tang Ming entered the small world and came to Dihuo Island.

After several transformations, the current Earth Fire Island is tall and majestic, like a towering giant mountain.

To refine such a large island into a magic weapon, the materials needed are absolutely massive.

Fortunately, Tang Ming is not short of these now. The refining materials he has accumulated are enough to support the needs of this refining.

These materials include parts from giant beasts in the Great Spirit World, products from the Primordial World, and many minerals from the Quicksand World.

Tang Ming sorted out the many refining materials, and then went to the interior of the volcanic island.

Under the island, magma surged, and fiery flames scorched the rock walls.

On the rock wall, various runes light up from time to time, which is a refined part.

Tang Ming took out various refining materials and put them into the ground fire furnace, using the power of the ground fire to melt them.

Then ingest these materials, destroy the spirit foundation of the ground fire furnace, and fuse these materials into the volcano wall.

Then enter runes in it and engrave formations.

This process is long and boring. In addition to the high requirements for refining techniques, it is also a huge test for mana.

Fortunately, Tang Ming is now in the period of crossing the catastrophe, and his magic power is far better than before, so it is not difficult to deal with it.

What's more, he still has so many spiritual fruit pills to replenish vitality, and water, fire, and flow flames to assist in refining materials.

At critical moments, you can also ask Tang Bingpo for help in refining.

With the help of Tang Bingpo, pieces of ore and animal bones were melted and refined into the volcano wall.

Finally, the last piece of ore melted in.

All that is left is to communicate with the spirit veins and guide the spirit veins into the furnace of earth fire.

For this step, he had planned for a long time. He had already invested spiritual foundations such as spiritual eyes and spiritual springs on Dihuo Island.

After such a long period of development, it has long grown into a small spirit vein.

But these were not enough, Tang Ming communicated the super spiritual pulse of the central island here again.

In the future, no matter whether it is refining weapons or alchemy, you will not be afraid of lack of spiritual energy.

Not only that, but the quality of the refined artifacts will be even higher.

At this point, the magic weapon level ground fire furnace has finally been practiced.

The ground fire furnace emitted a powerful wave, which disappeared in a flash.

With excitement, Tang Ming felt carefully.

The current Earth Fire Furnace is a seamless one without any blemishes, completely compatible with this small world.

On the inner wall of the earth fire furnace, lines are regularly arranged vertically and horizontally, and mysterious runes are faintly visible.

Feeling the upgraded ground fire furnace, Tang Ming was very satisfied.

But he still wants to go further, he wants to quench the ground fire furnace.

The quenching of mortals is to pour cold water on the forged utensils, and use the temperature difference to make the quality of the forged utensils better.

The earth fire furnace is so big, even if he can mobilize the water of the sea to quench it, it may not be of much help.

But Tang Ming had other plans. He sent out a divine thought, and Tang Bingpo appeared above the earth fire furnace with the artifact Guanghan Mirror.

Tang Bingpo mobilized the power of the world and poured it into the Guanghan Mirror, and the Guanghan Mirror emitted a white light and shot it towards Earthfire Island.

In the next second, the entire Earthfire Island turned into a towering icy mass, standing in the sea.

The temperature of the entire sea surface also dropped sharply, and a thin layer of ice formed on the sea surface.

It is probably the only one in this world to use an artifact to quench the fire, Tang Ming thought to himself.

He mobilized the power of the world and poured it into the furnace of earth fire.

The magma in the ground fire furnace surged again.

When the ice cubes are fused, the quenching is complete.

But it doesn't happen instantly.

The Guanghan Mirror is a divine weapon. The ice cubes it creates are solid and immortal, and they are not so easy to melt.

After doing this, he walked out of the small world.Participated in patrol missions.

The patrol mission here is no different from the original one.

It is also a team of 100 people, going to the designated place to investigate whether there are any intruders who took advantage of the smuggling.

Tang Ming followed the patrol and searched carefully along the way.

Under his delusion-breaking pupils, he found a few intruders who were hiding in the dark and were about to smuggle.

Patrols quickly took the intruders down.

There are many patrols here, and they generally have a relatively high level of cultivation.

What's more, Tang Ming is still there. Tang Ming, who has entered the tribulation stage, with the help of the power of the world, is enough to beat the gods.

What's more, he still has so many artifacts, even if he faces an existence higher than a fairy, he is not without the power to fight.

Dealing with a few smuggled intruders is naturally a no-brainer.

After the patrol team took down the stowaway, they continued to patrol for a few days and found nothing unusual.Even if the task is completed this time.

Go back to the dormitory and enter the small world.

Tang Ming discovered that the big ice lump on Dihuo Island had completely melted.

The ground fire furnace has been quenched, and the quality has been improved.

Now, it's time to refine the Soul Cultivation Tower.
