Sedum explained with a fierce fire bomb, and Fang Yue could understand that in terms of croquettes, he couldn't figure it out.

Instead of grinding with him, Sedum chose a stone protruding from the edge of the swamp and decided to make a fire bomb here, and he had other ideas he wanted to test.

Of course, this kind of fierce fire bomb can be made of black mud, but Sedum wants to make it hollow, and it has to be filled with real stone fat oil, to put it bluntly, it is a kind of sandwich meatball, so it is not an exaggeration to call it "croquette".

And Sedum has other thoughts and thoughts, this kind of stone grease oil has a relatively high melting point, that is, it is difficult to ignite it with an ordinary flame, but once burned, it is very violent.

Since all fires are difficult to burn, but it is not equal to the spiritual fire of spells is also difficult to burn, although his own small fire control technique is very poor, but it is very simple to ignite the stone fat fire oil.

In addition, I am afraid that Fang Yue's sword fire can also be easily ignited, in order to confirm his thoughts, Sedum only needs to make two croquettes and test it.

And the two bullets that were rubbed out were placed in the palm of his hand, Fang Yue stared at them, his face still not quite convinced.

Sedum picked one up and threw it into the air, and then used a small fire control technique! I only heard a muffled "pop!" in mid-air, and a ball of fire lit up, and then fell to the ground, but the stone fat oil inside was still burning.

"You see, I can easily ignite the oil in it, and the people of that world say that this oil needs to be refined, otherwise there are too many impurities and it will not burn easily. Sedum said to Fang Yue.

"What's the use of this, my sword fire can also ignite it, and besides, the bullet is soft and collapsed, and it doesn't have the kind of explosion you said at all!" Fang Yue shook his head.

"You have to rely on the sun to bake, don't be so stupid, the more the mud pill is sealed, the more the stone fat oil inside will explode after it is burned! Because everything needs air to burn, and once the air is exhausted, the confined space will not be able to withstand it and explode! This time you understand?"

Sedum didn't know if Fang Yue could really understand this explanation, because the knowledge in it did not come from this world, but from another world.

Sedum sometimes thinks that the people in that world are really powerful, and they know how to use the essential elements of matter, especially that explosive, so as to immortalize the power of destroying the world, but why have they been enclosed in that abandoned world?

Could it be that they invented weapons only to satisfy their own ambitions, so as to kill more of their own people?

Such a question, Sedum would not be able to figure it out for a while, but Fang Yue gave him an affirmative answer.

He said, "I don't understand, but if you say so, then I believe you." ”

These words moved Sedum, it is a very touching thing to be trusted by others, isn't life all about seeking to be affirmed and respected?

"Do you know how to form formations?" Sedum asked Fang Yue, who shook his head.

Sedum felt a pity that his little knowledge of the formation from the books obviously could not be applied to the projectile, and it was difficult to engrave it on the skin, otherwise, the power of the explosion of the fierce fire bomb would be even greater.

But he still tried the magic of the formation application, but now he needed to think about something more urgent.

What his small fire control technique needs is the spiritual power of the meridians in his body, which is a limited little bit, and can he really control how far he can control it? I don't count it, I'm afraid that more than one zhang will be completely useless.

In comparison, Fang Yue's sword fire control was much more powerful, at least within three zhang, his sword fire was completely capable of detonating that fierce fire bomb.

With this in mind, Sedum decided to use the slingshot himself, while Fang Yue detonated the fierce fire bomb, provided that he had to play the slingshot skillfully.

So Sedum took Fang Yue's slingshot and ran to the side to practice, leaving Fang Yue to make a "fierce fire bomb" on the edge of the stone!"

The manufacture of this projectile is not troublesome, Sedum followed him to make a few and put them on the stone to dry, the sun is not bad today, the sun is also blazing, and the black mud mixed with oil is oily and will become very hard.

Sedum and Fang Yue have both experimented, Fang Yue's sword fire can indeed detonate the projectile at a long distance, what Sedum didn't expect was that after the soft projectile exploded, the grease inside fell and still burned violently, even on the sand, it would always burn for half a day.

"It looks like a Yin Soul Flame!" Fang Yue said.

The rumored Yin Soul Fire is very vicious, once it is contaminated, it can't be gotten rid of at all, and it will not be extinguished until it is burned to ashes, but mortals who are stained with this kind of fire will basically burn together with flesh and bones, and they can't be scraped off with a knife.

Oil burning is difficult to extinguish, and when that puddle of oil falls to the ground, it will still continue to burn, accompanied by this black smoke, and even a stench, which is indeed a bit like a ghostly fire.

Fang Yue felt like a return, but after all, they were two different things, Sedum's idea was really good, after the explosion of the fierce fire bomb, it could ignite the body, and it was easy to get rid of it, I am afraid that those assassins were really uncomfortable.

The footsteps sounded, Sedum walked briskly, and then threw a dead wild bird, this bird is really not small!

"How can I make progress and fast?" Sedum was a little proud.

Fang Yue nodded, at this point, Sedum did make very fast progress, compared to dead objects, it was easy for the slingshot to aim and exert force, but for fast-moving objects, it would take a lot of tests to use the slingshot.

It is already very telling that such an obese wild bird can be hit by Sedum, and of course they will eat this wild bird for lunch today.

"I'm still thinking, the formation can't be said to be completely useless, I just chose a place, but I arranged it, I think it should work, how about we fight back against those people tonight?"

Sedum discussed his thoughts with Fang Yue today, but Fang Yue shook his head and said, "Although the terrain here is complicated and there are many forks in the road, they will always touch it, unless you go to be a bait." ”

“...... And we've wasted a day, the other party can only be closer to us, and we are still prey in this game. ”

Sedum smiled and said: "Then you need to teach them a lesson, and those who want to take me as a prey need to pay a price." ”

He was very confident, Fang Yue couldn't understand why he was still so confident today, the two of them were weak in cultivation, and they couldn't compare with adults in terms of age and experience, and at this time, Sedum still didn't care.

However, this also made Fang Yue feel very combative, and sometimes the confidence of his companions can indeed be infectious, Fang Yue felt that believing in Sedum should be right, just like believing in his fierce fire bomb.

After nightfall, the two of them, who had made a lot of preparations, set off again, walking towards the depths of the grassland behind them, in the direction of the northwest.

Huanglong's huge aura seemed to be moving in a southwesterly direction, so Sedum chose to go in a northwesterly direction, but they didn't go far before they stopped in a sparse wood.

The grass here doesn't grow very tall, probably because the trees absorb the rain and nutrients, but it's enough for the two of them to hide their bodies.

"Did your arrangement just now work?" Fang Yue said in a low voice, he was purely small talk.

Sedum looked at the starry sky and the moon in the sky, and there were faint thin clouds drifting by, blocking the moonlight, and the world became darker.

"Once you succeed, you have to remember which direction you've been running, otherwise we'll be separated, and I don't want to be separated from you again. Sedum whispered.

"Don't worry, even if you are separated, I will go to you. Fang Yue said in a deep voice.

"Shhh......hhhhh

He had been using the Qi Observation Technique all the time, even if he didn't observe too far away like that, but it was possible to detect some subtle changes in his breath.

With a calm mind, at the edge of the woods in front of him, there was indeed a breath that was getting heavier and heavier, and Fang Yue looked at it with his eyes, and there seemed to be a black shadow flickering faintly.

He also wondered, these were obviously higher than his cultivation today and himself, but he didn't dare to appear during the day, why did he have to wait until night to come?

Now was not the time to think about it, his eyes were fixed on the front, and both he and Sedum were ready.

Suddenly, there was a shrill chirping sound ahead, followed by several successive "boom...... beeps!", followed by an angry shout.

Sedum jumped up, and pointed at the spiritual power in the meridians, which seemed to inspire something, Fang Yue thought at this time, could this guy really understand the formation?

"......Boom!" a burst of red light erupted, followed by a large flame.
