Skipping the noisy episode, Yang Hao quickly found Qi Guang in the reserve group, and he saw Yang Hao throw over a thorn grass seed without saying a word.

Yang Hao put on a new thorn grass and felt it, and his back stinged slightly.

"Brother Hao, the new thorn grass will be entrenched in your back, and under the protection of the breastplate, the bonuses provided will be more stable, but there will also be some side effects. Attacks taken from behind will be increased by 2, and the pain will be increased every time you are attacked, about 10%. Qi Guang slowly explained the characteristics of the new thorn grass.

"Damn, such masochism! But it's really much better than being out on the outside, so let's cultivate a group according to this, and if you succeed, you'll be turned into an official member. By the way, what have your two brothers been up to lately? Yang Hao said that it was nothing to be handsome.

"Oh, the second brother is obsessed with alchemy, and he inserts tubes into himself all day long, and the eldest brother is still experimenting with the possibility of light witchcraft and has burned the house several times." Qi Guang said plainly, hearing Yang Hao's cold sweat, he was ashamed of himself, this is the correct attitude to study witchcraft. Yang Hao said that he couldn't afford to provoke him, and agreed to provide corresponding resources and left in a hurry.

The next few days were quite dull, Yang Hao took classes in Kai Mohan every day (mainly to learn the Law Seal), and when he had time, he did difficult tasks with the task maniac Gale Gale, and he didn't fall much behind, and he made steady progress towards the level 14 mark.

At the same time, during this time, Yang Hao began to preliminarily study the power of the earth and his own witchcraft advancement.

In fact, for trick-level witchcraft such as sprinting and scorching weapons, after advancement, it will only increase the power of a little bit, and there will be no qualitative change, and the value of its existence is to upgrade the witchcraft of the majority of players to deal with monsters with higher and higher magic resistance.

As for the sorcery-like magic like the Flame Cover and the Sonic System (beyond the trick and not reaching the sorcery level), Yang Hao believes that even if it does not reach the sorcery level after advancement, it will be greatly improved.

But the difficulty is also rising exponentially, and no player has yet revealed the information of this level of witchcraft advancement, perhaps the successful one has concealed it, after all, there are not a few guys who like to make a fortune in silence.

At this time, Lao Yang Na's research has made a lot of progress, of course, not referring to the bursting arrow, but the black ore that Yang Hao came back.

Through the identification of scholars, this kind of ore is called Morris ore, also known as fire sulfur ore, which is a relatively common mineral deposit in the fire dragon nest, and its original form is just ordinary iron sulfur ore, which is gradually transformed into fire sulfur ore rich in fire elements under the erosion of dragon fire.

In Lao Yang's experiment, it was found that the pyromeric ore is very stable when it is in a large solid state, and it is okay to fall hard, but it is very easy to spontaneously ignite and explode after grinding into powder, which is very dangerous.

Later, under the research of many people, the material that caused the instability was the red and yellow material present in the pyrometry. The distribution of this material in pyrometry is very rare, and the distribution is very finely fragmented and dotted. Once this substance is exposed to the air, it will react violently and contain great elemental energy, so everyone named it fire sulfur.

Later, everyone began to study how to safely extract fire sulfur, because it was simply the perfect material for making magic energy bombs and bursting arrows, and Gu Lao Yang calculated that if they could make magic energy bombs with fire sulfur, their power would be more than five times that of now.

The members of the research team led by Lao Yang are all veteran comrades with decades of experience in mechanics, chemistry and engineering, and now they have gained a young body and almost unlimited energy in the game, which is quite the mentality of an old man who is crazy about teenagers.

After three days of frantic research day and night, Lao Yang interrupted Yang Hao's meditation with a tube of high-purity fire sulfur the length of his little thumb, and said: "Son, in general, we have mastered the method of purifying fire sulfur, inert gas and a confined environment can be used to store it, but it still needs to be studied in practical use, so we need more ores and gold coins, you know your mother she..."

"Understand, you don't have to worry about Dad's ore, I will send people from the reserve team to transport it back, just so that they can have enough contributions in exchange for the gray dwarf armor in the warehouse, and I will also support you with gold coins, but try to save a little, the group has been spending too much money recently."

"Got it, I'll give you this fire sulfur, and you can think about it with your brain, and go." After Lao Yang finished speaking, he left in a hurry, full of energy.

Yang Hao wrenched his fingers and counted how many gold coins he had spent this week and how many gold coins he had earned, and found that if he hadn't robbed the treasure of the Great Spirit Gang, the demon hunting group would have gone bankrupt long ago.

The main reason for this is that the sales of Yellow Moon Potions have been greatly reduced due to the retreat of players, and the cost is getting bigger and bigger, although these gold coins are being converted into the combat power of the Demon Hunters, but the financial collapse is definitely a disaster.

"It's a real headache to find a way to make money!" Yang Hao rubbed his temples.

At this moment, Tang Zijin asked for a voice call:

"Brother Hao, why have you been quiet again? Is it a premeditated move? ”

"Fart, I'm trying to turn positive, I don't have time to do things, what to say quickly, I'm annoying!"

"OK, Brother Hao, I'm here to send you money, you have to be polite to me."

"Really? No, you kid is so good, can you let me take advantage, is there any dirty work again? ”

"What is this called, when did I cooperate with you, you didn't take advantage, aren't you ashamed?"

"Hmph, why be ashamed of taking advantage of your ability? Get down to business! ”

"You must know the copy of the essence of fire, it was made by your wolf warriors."

"Nonsense, this dungeon needs to be level 15 to get in, why are you using your brains, are you already level 15?"

"Of course not, I'm only in my early 13th grade, I said Brother Hao, you are not well-informed enough. The monsters in this dungeon have escaped! ”

"Damn, the monsters in the dungeon can still run out, you tease me!"

"Seriously, there are a lot of wandering fire elements outside the dungeon now, and their strength is very strong, so we urgently need a master like Brother Hao."

"Ha, how many days have you thought of me? Hehe, you've suffered a loss, tell me how many times you died? ”

"Ahem, Brother Hao, just say if you don't come, I also found a boss."

"Send the coordinates, and I'll be there soon."

At the end of the voice, Yang Hao and Dafeng explained a few words, and led Volibel to the hometown of Baiguoyuan Village.

The main reason for his visit this time was to find out the strength and various skills of the fire element, so as to clear the way for future dungeons, and secondly, for Volibel.

With the improvement of Yang Hao's level, Volibel's strength became more and more unable to keep up, and Yang Hao did not bring it in the previous battles.

Yang Hao is more nostalgic, and Volibel has been with him for so long, and he has a lot of feelings.

For this reason, Yang Hao consulted Ye Naifa that if a magical beast like Volibel wanted to get closer, the only way to do it was to improve his bloodline or transform into a half-elemental creature.

Both are very risky, and even if Volibel has the talent to save his life, if he fails, he will be a wasted bear.

Volibel's intelligence is high, equivalent to that of a human child, and it strongly hopes to fight with Yang Hao instead of crouching in Kyle Mohan and becoming Erin's pet.

Yang Hao rubbed its head and said, "Man, your future depends on this one!" ”

"Roar!"

"Haha, the morale is good, you're right, we'll definitely succeed!"
