Heavenly Dao Formula

Although Qianyan didn't know all the details of the ditches, she still knew roughly that there was a main canal under each of the four main streets, and that there was a horizontal branch connecting the main canals every three or four rows of streets. If it is drawn on paper, it is roughly like a spider web, and it becomes more and more sparse from the inside to the outside.

She is now sitting above a branching ditch.

No one noticed that a lot of frost had formed under these deep ditches.

The task Xia Fan assigned to her and Qianzhi was to turn the drainage channel in the outer circle into a huge "water storage tank". All the undischarged water flow was directed into the horizontal canal on the west side of the palace, making the water level here exceed the main canal below Baihu Avenue.

Through the drainage holes under her feet, she could see that the standing water was about to overflow the ground. This kind of scene that only appeared during heavy rain was obviously not normal, but few people would notice this abnormality.

After all, even if the water overflows, it will at most cause a little inconvenience to the people celebrating. When the ditch is unblocked, the water will naturally dissipate. Who will treat it as a major event?

In fact, even Qianyan didn't think it was a big deal.

According to Xia Fan, the "celebration gift" he sent could concentrate all the defense forces of Shangyuan City to the west block, but it was really hard for her to imagine what could be done with the rain and sewage.

By the way... He seemed to say that it would explode?

"Look, the palace gate is open!"

"That's the worship group that set off first, right?"

"Will His Royal Highness show up?"

"Fool, he is now the emperor!"

Suddenly, cheers erupted from the crowd.

For the people, things done in the palace such as persuading officials to enter and issuing edicts have nothing to do with them. What they can see is that King Xinqi started from Baihu Avenue and went all the way to Lingshan Ancestral Temple to worship. This process will last for most of the day, and there are performances, music, fireworks and firecrackers, which can be regarded as very lively. Therefore, when the west gate of the palace wall was opened, the voices of the onlookers immediately reached a new high.

This is also the time to act in the plan.

Qianyan took out a mass of gun cotton soaked in grease from his bosom, carefully lit it, and stuffed it into the hole under his feet.

The moment the gun cotton was about to enter the water, an ice crystal boat quietly condensed into shape, supporting it just right.

After completing the preparations, Qian Yan stood up, passed through the crowd, squeezed to the side of Baihu Avenue, and stomped his feet at the intersection of the canal.

A newly raised piece of solid ice suddenly pushed open the ice-sealed crossing.

The hoarded sewage immediately resumed its flow, but this time, it flowed from the outside to the inside, pouring back into the main canal.

If it is normal, people standing on the street can even hear the rushing sound.

But at this moment, the hustle and bustle of the city completely covered up the sound of the water.

With the help of the water, the ice boat also moved. It dragged the gun cotton through the ditch, and soon entered the bottom of the White Tiger Avenue.

So far, Qianyan's mission has been completed.

According to the plan, she should leave the main street immediately, head towards the west gate, and take advantage of the chaos to withdraw from Shangyuan City.

However, the living dead did not move.

Because she was also curious about what Xia Fan had been doing here for nearly two hours.

In a place that Qianyan couldn't see, the speed of the ice ship had obviously slowed down—the size of the main channel was much wider than that of the branch channels, and the amount of water accumulated before could not fill the main channel, so after the water flow merged, the water surface was very large. Soon a new balance will be formed.

Under the scorching of the flames, the ice ship itself began to melt, and the dripping water droplets had already accumulated half a palm-sized puddle at the bottom. It's just that the grease does not melt when it meets water, and the oil film they form makes the gun cotton continue to burn on the water.

That weak light also slightly illuminated this land that never sees light.

If someone can sneak into it, they will find an anomaly in the main canal.

It was supposed to be a paradise for rats and insects, and with the fish fry or floating leaf plants floating in from the landscape garden, this place can be regarded as a unique biosphere.

But now the channel is dead.

The corpses of animals can be seen everywhere, whether it is rats, fish, poisonous insects or snakes, they all float on the water motionless, as if they have all been killed. The surfaces of many animals were even scorched black and smelly, and their bodies were still steaming.

In other words, the ambient temperature here has reached an unbelievable level. Even in the daytime, there are bursts of white air coming out of the drain holes beside the main road, like steaming springs in the mountains.

When the iceship rounded a corner again, the brightness of the flames instantly soared.

Its outline expanded, and soon it outstripped the iceship itself, so that it seemed to take off. Once such a change starts, it cannot be stopped. Almost in the blink of an eye, the flame has already expanded into a fireball, and changed from a dull reddish yellow to a dazzling blue-white.

In the next second, the raging flames spread further along the waterway to half of the main canal, and the air above the stagnant water seemed to be ignited at the same time, heating the already warm space to hundreds of degrees in an instant! This high temperature caused the water body to evaporate rapidly, and the small drain hole could no longer meet its release needs.

Then Qianyan heard a loud bang!

I saw that the ground of Baihu Avenue suddenly bulged, and the solid stone pavement suddenly looked like it was made of soft mud. Such a huge deformation directly caused the ground to break and crack, and then white air waves spurted from the ground, blowing the bricks away. Shi directly rushed to a height of tens of meters!

And the explosion is far from over.

Like a series of firecrackers, it exploded towards the imperial palace step by step. The successive roars made the ground tremble, and the white smoke that erupted successively formed a towering "smoke wall" on the White Tiger Avenue!

Qianyan was dumbfounded.

In her impression, only gunpowder can cause such an earth-shattering effect. The problem is that sulfur and saltpeter are strictly controlled medicinal materials, and she has never seen Xia Fan hoarding these things. Having said that, even if he suddenly conjured dozens of large bags of gunpowder, it would be impossible to stuff them into the underground drain under the eyes of everyone!

This sudden upheaval caused the crowd to panic, they retreated in panic, and poured into the surrounding streets and alleys from both sides of Baihu Avenue. If it weren't for the fact that a series of explosions were heading towards the palace, their escape would have been even more chaotic.

The most violent reaction was undoubtedly the worship team that had already walked out of the gate of the palace wall. Those gorgeous court ladies were so frightened that they dropped the brocade and flower baskets in their hands, screamed and ran into the palace with their heads in their arms. The guards clearing the way ahead were not much better. Many even dropped their flags and fled to both sides of Baihu Avenue, fearing that the explosion would happen at their feet in the next moment.

This "thunder on dry land" is not only a gift for the enthronement ceremony, but also a signal for the opening of the curtain.

Hearing the roar, Qianzhi lowered the same ice ship closer to the palace.
