The narrow space, complex terrain, and the presence of strong enemies stationed in Xia Fan, not to mention that Xia Fan had only a few soldiers under his command, even if he had a professional army of alchemists, he was reluctant to throw himself underground to fight the enemy to the death.

The best way to deal with enemies hiding in fortifications is to blast.

Enemies may be wary of incense, poisonous gas, and even fire, but harmless flour and sawdust are different, and even if they are aware of it, they are prone to delay and hesitate in judging their intentions.

This hesitation is often fatal.

By the time there was movement from below the patio, more than thirty bags of powder had been poured into the vaulted lobby, where they were inconspicuous and indestructible in the dark, and could even be boiled into a paste when collected.

"Luo You'er, it's your turn. Xia Fan glanced at the little girl.

Although Luo Youer didn't know what would happen next, she still performed her second best spell as planned-

"Xunshu returns, whisk willows!"

is called Whisk Willow, but there is a strong wind in front of her!

The gust of wind, under her control, poured straight to the bottom of the well.

"And then?"

"Next up to me. ”

Xia Fan knew even if he didn't have to look at it that the dust below must have been swept everywhere by this strong wind, and when they were fully mixed with the air, the last step only needed to provide a little ignition source.

There's no more convenient way to ignite than lightning.

Xia Fan threw up the copper wire pendant and performed the most familiar magic.

"Earthquake Return, Thunder!"

The moment the electric light tore through the air and pierced the wellhead, the earth boiled!

The ignited flour and sawdust burned each other, transferring the heat to their companions at an unimaginably fast rate, and almost instantly, the flames filled the entire hall. Driven by the heat, the air expands violently until the existing space can no longer hold it.

"Boom ——————————————"

With an earth-shattering loud bang, a wave of hot air erupted directly from the patio, like a sky-high fire. The buckets and wooden shelves hanging above the wellhead were torn apart like pieces of paper, and even the bricks on the side of the well were lifted several times.

Xia Fan felt the ground under his feet be punched.

But that's far from the end.

Just when everyone was looking stunned, the second explosion came as promised, even more violent than the first!

This is due to the low pressure zone created at the center of the explosion, which causes the surrounding air to be quickly inhaled.

The first blast had lifted up all the unignited dust, which amounted to a more thorough mix. The inhaled dust instantly exceeds the concentration of suspended combustibles in the center above the critical point, while the air of hundreds of degrees can re-ignite the newly added fuel, even without the need for an open flame.

This time, the pillar of flames that erupted from the patio rushed out more than ten meters away, and even if it had retreated to the fence, everyone could still feel the hot wave coming to their faces.

The participants who were still skeptical about this before are only shocked and confused in their hearts at this moment.

It's obviously something to eat, even if you add some sawdust, it's just that it can be burned, why does it have such a terrible power when mixed together?

It's a bit unbelievable.

Ning Wanjun faced the hot wind, looking intoxicated.

She didn't have much doubt about the results in the first place, so it was easier to appreciate them.

This trip was not in vain.

The princess seems to have returned to the familiar frontier battlefield, fighting the enemy to the sound of fireworks and drums.

Sure enough, compared to sitting on the court, it was more pleasant for her to go to the front line in person.

The only fly in the ointment was that she thought that Xia Fan's move would only weaken the strength of the East China Sea Gang, and in the end, it would be up to Fang Shi to decide the winner. But judging from the current situation, she feels that even if there are still people alive below, there should be no way to deal with her.

On the other side, May Yao opened her mouth wide and couldn't come back to her senses for a long time.

She was still worried about whether the princess would win this battle and what price she would pay, but now the thought in her mind had become another - if the news of the killing of the sorcerer by flour and sawdust was transmitted back to the other side of the sea, I don't know how the people of Dongsheng Kingdom would feel.

I probably don't hesitate to denounce it as an absurd lie, right?

"Is this how Qiguo used magic in the first place...... After being shocked, Nagi Hong said thoughtfully, "It is worthy of being the successor of Yongguo, and this trick can also be used by us." ”

"Definitely. Nagi Qing nodded with a sigh, although gunpowder with saltpeter and sulfur as the main materials can also achieve such an effect, but the collection of the former is much more difficult, and the opponent will also be doubly vigilant, and the people are not allowed to sell it privately. Flour is different, as long as it is planted, it can produce steadily, and there are many people who are proficient in Xunshu and separation. "With a little bit of utilization, assassination will become more difficult to guard against. ”

"What are you talking about?" only Shan Hui looked curious.

"No......" Nagi Hong and Nagi Qing glanced at each other and chose to ignore it, "It has nothing to do with you." You'd better go to Lord Li, when the smoke clears, they will probably go down the well. ”

The truth is that the wait is in the morning.

The temperature in the tunnel dropped extremely slowly, and even if Luo You'er had been using Xunjutsu to ventilate, the air waves gushing out of the patio were scorching. Fortunately, Xia Fan was prepared, and the princess troops guarding the corner of the street were not only a reserve force to prevent the Donghai Gang from escaping, but also a reliable choice to block the scene.

It was impossible for the two loud noises at night not to attract the attention of the local residents, so he simply asked Xu Sanzhong to cordon off the Redwood Building and the surrounding two streets, and check the identities of the people on the two floors one by one - if the Donghai Gang still had fish that slipped through the net, there was a good chance that they would be the guards hidden in the inn and the Qinglou.

It wasn't until the dawn of the sky that Xia Fan led everyone into the tunnel from the mouth of the patio.

After two rounds of impact, the iron fence had long since slackened, and a few stomps allowed it to completely separate from the vault.

By this time, the smoke had basically settled, the air was filled with an unpleasant smell of burning, and the walls were covered with black marks of burning.

After stepping on the ground, the first thing that caught my eye was a dozen or so corpses, their limbs were hardly complete, and the exposed parts were even more charred, and the coagulated blood scabs looked like lava embedded in the dry surface.

These men were supposed to be closely monitoring the patio in case someone suddenly broke into the lobby from above the dome, and thus became the first to be affected by the explosion.

But the way they died was already considered lucky.

Farther away, such as the entrance to the aisle and the edge of the lobby, there were also large numbers of people lying down. These white-robed warriors had hideous faces, purple skin, and their throats were covered with blood. They were noticeably more painful than their accomplices, who were instantly unconscious. After the explosion, the air here became unusually hot, breathing was a quick suicide, holding breath was a chronic suicide, and the only thing they could do was choose between the two.
