Bai Yujun is very busy.

The portal capable of transporting tens of thousands of troops is complex and mysterious, and the dragon's head has no time to spare.

The huge project is too busy for him. Mu is responsible for most of the design, and is assisted by the immortal craftsmen who defected to the old heaven. The teleportation bridge must be built before the expansion and reorganization of the snake demon empire is completed. Otherwise, there is no talk of saving the world. In short, he works day and night.

Just live.

Use the gantry as a template to build a simplified version of the gantry.

It took dozens of days to finally make progress, but when the barrier of the small world was penetrated, it was blocked by the will of heaven in the world and could not penetrate the barrier...

Small broken ball world, high mountain top.

An archway with a simple style is full of glory.

A fuzzy light curtain separates the two worlds at the stone gate. The world inside the door is blurred as the light curtain sways. You can vaguely see the mountains, flowing water, blue sky and white clouds. It is completely different from the world you are in. The teleportation bridge is only the last step, which is also the most difficult.

Capture any low-level evil cultivator prisoner for experiments and advance to the stone gate.

The two craftsmen were not polite and stepped forward with a kick.

"ah……!"

The low-level evil cultivator tried his best to penetrate the water curtain, but not far forward, a repulsive force suddenly pushed him back.

He fell facedown to the ground with a snap, knocking out two front teeth. The unlucky low-level evil cultivator couldn't figure out what happened to him. His kung fu was tested several times in just a few days. The previous low-level evil cultivators were even worse and tortured.

Inhuman form, the semi-finished teleportation bridge is more terrifying than various instruments of torture.

"Failed again..."

The immortal craftsmen were at a loss.

"It's difficult to do. Even the Heavenly Immortal Bridge could only teleport to the big world in the past. It's very difficult to enter the small world even with the heavenly documents and decrees. Only a few immortals can do it."

The Immortal Bridge outside Nantianmen also cannot be directly transmitted, which is particularly complicated.

The will of the Heavenly World is very repellent, it is self-protection, and there may be loopholes that can be exploited.

You can't imitate the evil spirits. The demon invasion uses brutal and destructive means to get through the loopholes. Bai Yujun worked hard to repair it before, but the passive defense effect was not ideal, so now he plans to use conquest to deal with the evil spirits.

The craftsmen of the former Tianting Craftsmanship Department continue to make various attempts...

Bai Yujun frowned and walked into the stone door.

Passing through the water curtain, my vision wavered for a while and then became clear again. The breeze blew through the grass and brought up dandelions. It was an ordinary little world.

Little Phoenix also came over to join in the fun, but after the novelty wore off, it felt very boring.

An ugly six-winged demon flew towards me, its mouth was densely packed with teeth, and its legs were bent backwards. It held an iron rope in one hand and a ghost-headed sword in the other, and rushed towards it menacingly.

The little phoenix happily threw a spark over, and when the spark fell on the demon, it was instantly burned from the inside out to ashes.

There is no problem with the simplified version of the low-end gantry, everything is normal. The problem is that only I and the Phoenix can pass through the barrier. In fact, it is still a natural ability of the special beast. It is completely ineffective and meaningless to replace it with others.

Shaking his head, he led Little Phoenix back to the world of Little Breaking Ball.

He frowned and pinched his chin in worry.

"Hey, it doesn't make sense?"

Behind him, the underage little Phoenix imitated distress.

Mu Fei sat down on Bai Yujun's shoulder, looked at the stone door and then at the craftsmen of the Craftsmanship Department.

"Heaven's decree..."

"There is no place to get the decree from heaven now, and even if we get it, it won't work."

Shrugging, Bai Yujun knew clearly that Heaven's decree was not written casually, not to mention that it was impossible to achieve it now.

Mu turned to look at a certain Bai's pretty face.

"Bai, you can try writing a document. Only you can cross the world barrier at will. Oh, I almost forgot that the phoenix can also do it. Don't tear off the dragon scales. Try to attach the dragon energy or use the dragon's contract."

"I'll try, wait a minute."

If you don't have any materials, just use jade instead and try to make a token.

After pondering for a long time, I came up with the right words. I inlaid them with dragon energy without leaving any scratches. The writing was like a perfectly inlaid jade stone. The edges were exquisitely carved in the style of two dragons playing with beads. They were written in dragon language. Obsessive-compulsive disorder drove Bai Bai to try his best to make it as exquisite as possible.

, and finally made into a palm-sized magical pass command.

The most important thing is that Bai Yujun communicated with the small world on the other side seriously and religiously, using a junior tone of voice, treating her as her aunt, and easily gained the favor of that small world, and secretly agreed and recognized the pass code.

This talisman contains the will of heaven in the small world opposite, so it can only go to this place.

It was quickly produced successfully.

"Take it and try it."

The craftsman grabbed the command talisman and was about to hand it to the low-level evil cultivator. Before he could get close, he heard the evil cultivator scream.

"Ah... don't come here... spare your life..."

The evil cultivator's whole body seemed to be burning with blood and sinister aura.

Everyone looked at each other.

Bai Yujun and Little Phoenix behind him rolled their eyes speechlessly.

Afraid that the aura of the dragon and the phoenix would destroy the evil cultivators, they deliberately restrained all their auras. However, the token would not be restrained. Not to mention wearing it on the body, it would burn the evil cultivators to ashes if they got close. The dragon aura and dragon power contained in the token

The agreement says that no evil spirit can come close.

Raise your hand and snap your fingers casually.

Pa~

The evil cultivator burned instantly and fell to the ground into ashes before even letting out a scream.

He nodded to the half-dragon man next to him who had not yet become an immortal.

The young half-dragon took the token without saying a word and walked directly to the stone gate. A magical scene happened. As the token approached, the water curtain of the stone gate opened and became larger and larger. The young half-dragon could clearly see the scenery on the opposite side. It was very easy for the young half-dragon.

Cross the world barrier.

"Success!"

The craftsmen cheered and the half-dragons who were watching were also excited.

Mu is very satisfied with this. Although the current function is a bit poor, it can be gradually improved. I believe it will not take long to build more transmission bridges.

He flew to the top of a certain white man and sat between the two dragon horns.

"Bai, you can find a way to mass-produce it. I will continue to improve the teleportation bridge. It must be tall enough to pass through warships and spaceships, and it must be open for a long time. The talisman can be divided into different functions, such as small teams crossing and large-scale armies.

It would be better if the design was more detailed.”

"It makes sense. I will add a restriction to prevent the talisman from falling into the hands of evil thieves."

"That's right, you have to control all the pass codes, and you can learn the strict decrees of heaven."

The command talisman is equivalent to the key to the world, and it is of great importance.

It is expected that there will be no free time for the next few months. Mu will be responsible for upgrading and expanding the teleportation bridge, while Bai Yujun will continue to study the production and improvement of the talismans.

Sigh, I have been tired and thin lately.

He turned around and looked at the opened portal.

Directly issue an order to arrange for an army of ten thousand snake demons to clean up the monsters, and arrange for the half-dragons who have not yet survived the catastrophe to become immortals to follow them. There will be no delay in exterminating the monsters and recruiting troops, and will leave other matters regarding the recruitment of troops to Qiao Jin and other generals.

After the arrangements were made, we began to study improved pass tokens.

Southern wilderness.

Qiao Jin quickly mobilized 10,000 troops.

It has been particularly lively recently. Countless armored ships are waiting quietly in the sky. Humans and monsters gather to watch, looking longingly. They are curious about where the world hanging upside down in the sky is, and even more curious about who is the enemy of the snake demon army. The hillsides, streets, and rooftops.

There are even figures of all ethnic groups on the river boats.

Just when countless eyes were watching curiously, there was a sudden wave of spiritual energy...

There are two ancient sacred trees in the southern wasteland, one is Mu and the other is Xi, one big and one small next to each other.

Even the small one is a mountain range.

Under the scorching sun, Xi suddenly moved, lifting up a thick tree trunk and extending it towards the sky. The green branches and leaves grew rapidly, and soon went straight into the sky and entered the upside-down world, building a road to the sky connecting the two worlds!

Countless snake demon soldiers climbed quickly along the trunk of the tree.

At the same time, the assembled floating iron ships raised their bows and flew towards the upside-down world one after another.
Chapter completed!
