Heavenly Dao Formula

With a narrow space, complex terrain, and powerful enemies stationed there, not to mention that Xia Fan had only a few soldiers under his command, even if he had a professional army of alchemists, he would not be willing to throw it underground to fight the enemy to the death.

The most suitable method for dealing with enemies hiding in fortifications is blasting.

The enemy may be wary of incense, poisonous gas, or even fire attacks, but the harmless flour and sawdust are different. Even if they are aware of it, they are prone to delay and hesitation in judging their intentions.

This hesitation is often fatal.

When there was movement from the bottom of the well, more than 30 bags of powder had all been poured into the vaulted hall. In the dark, they were inconspicuous and would not cause any harm. If collected, they could even be boiled and eaten .

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

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

"Xun Shu returns to Chen, blow the willows!"

The name is Fuliu, but what is born in front of her is a strong wind!

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

"Then what?"

"Next to me."

Even without looking, Xia Fan knew that the dust below must have been blown everywhere by the strong wind. When they are fully mixed with the air, the last step only needs to provide a little ignition source.

There is no easier way to start a fire than a Thunderbolt.

Xia Fan threw up the copper wire pendant and displayed the most familiar alchemy.

"Return to Shock Technique, Thunder!"

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

The ignited flour and sawdust burned each other, and then transferred the heat to the surrounding companions. The speed was unimaginable. Almost in an instant, the deflagration flames filled the entire lobby. Fueled by the heat, the air expands violently until the existing space can no longer hold it.

"boom--------------"

With an earth-shattering bang, a wave of high-heat air gushed out directly from the patio, like a fire soaring into the sky. The buckets and wooden frames hanging above the wellhead were torn apart like pieces of paper, and even the bricks beside the well were lifted up several times.

Xia Fan felt that the ground under his feet was punched violently.

But it's far from over.

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

That's because a low-pressure area is created at the center of explosion, causing the surrounding air to be sucked in quickly.

The first round of blast wind has already lifted up all the unignited dust, which is equivalent to a more thorough mixing. The inhaled dust instantly made the concentration of suspended combustibles in the center exceed the critical point, and the air of hundreds of degrees can ignite these newly added fuels even without an open flame.

This time, the flame column erupted from the patio rushed more than ten meters away. Even though they had retreated to the fence, everyone could still feel the scalding heat wave rushing towards their faces.

The participants who had doubts about this before were left with shock and confusion.

Obviously it's something to eat, even if you add some sawdust, it can only be burned. Why does it have such a terrifying power when mixed together?

This is too unbelievable.

Ning Wanjun faced the hot wind with a face full of intoxication.

She had little doubt about the outcome from the start, so it was easier to appreciate it.

This trip really didn't come in vain.

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

Sure enough, compared to sitting on the court, going to the front line in person made her feel more happy.

The only fly in the ointment was that she originally thought that Xia Fan's move would only weaken the strength of the Donghai Gang, and in the end it would be up to the alchemists to decide the outcome. But judging from the current situation, she felt that even if there were still people alive down there, she probably wouldn't be able to accept her.

On the other side, Wu Yueyao opened his mouth wide and couldn't recover for a long time.

She was still worrying about whether the princess could win this battle, and what price she would have to pay, but at this moment, the thought in her mind changed to another one—if the An Jiashu was killed by flour and sawdust The news of the news was sent back to the other side of the sea. I don't know how the people of Dongsheng Kingdom will feel.

Probably would not hesitate to denounce it as an absurd lie, right?

"Did Qiguo use alchemy in this way..." After being shocked, Nina Hong thought about it, "As expected of Yongguo's successor, this trick can also be used by us."

"Indeed." Nagino sighed and nodded. Although gunpowder with saltpeter and sulfur as the main ingredients can also achieve this effect, the collection of the former is much more difficult, and opponents will be more wary, and the folks will not allow it at all. private sale. Flour is different, as long as it is planted, it can produce a stable output, and there are many people who are proficient in Sunda and Liju. "Assassination will become more difficult to prevent if it is used a little flexibly."

"What are you talking about?" Only Shan Hui had a strange look on his face.

"No..." Ning Hong and Ning Qing glanced at each other, and chose to ignore it, "It has nothing to do with you. You should go to Master Li. When the smoke clears, they will probably go down the well."

The truth is, the wait came in the morning.

The temperature in the tunnel dropped extremely slowly, even if Luo You'er had been using Sunda to ventilate, the air waves gushing out from the courtyard were scorching hot. Fortunately, Xia Fan was well prepared. The princess troops guarding the intersection were not only a backup force to prevent the Donghai Gang from escaping, but also a reliable choice to block the scene.

The two loud noises at night could not fail to attract the attention of the local residents, so he simply asked Xu Sanzhong to block the Hongmu building and the two surrounding streets, and check the identities of the people in the two buildings one by one—if the Donghai gang still has The fish that slipped through the net were probably the guards hiding in the inns and brothels.

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

After two rounds of impact, the iron fence had long been slack, and a few pedalings completely separated it from the vault.

At this time, the smoke and dust have basically settled, the air is filled with an unpleasant smell of burnt, and the walls are full of black traces of burnt.

After stepping on the ground, the first thing that came into view was a dozen or so corpses. It was hard to say that their limbs were intact, and the exposed parts were even scorched brown. The solidified blood scabs were like lava embedded in the dry ground.

These people should have been closely monitoring the situation in the courtyard at the time, in case someone suddenly entered the lobby from above the dome, so they became the first targets of the explosion.

But the way they died was considered lucky.

In places farther away—such as the entrance of the passage and the edge of the lobby, a large number of people were also lying down. These white-robed warriors had ferocious faces, their skins were purple, and their throats were covered with bloodstains. Compared with their companions who lost consciousness in an instant, they were obviously in much more pain. After the explosion, the air here became extremely hot. Breathing is a quick suicide, and holding one's breath is a slow suicide, and the only thing they can do is to choose one of the two.
