In addition to being traded through the trade fair, the monster materials can also be sold to the family, although the price is low, but it is trouble-free, and it can be solved all at once, and then exchanged for spirit stones or other resources from the family.

The flesh and blood of the mid-first-order earth rat demon beast, Su Yu kept it for himself to take it for his own cultivation of alchemy.

The animal skin, as well as the first-order early ground rock rat and the essence blood, were sold to the family in exchange for six lower-grade spirit stones.

Time passed slowly.

After coming to the Medicine Garden, Su Yu had more than several times more cultivation resources in his hands.

There are also forty-one drops of essence blood of the mid-order ground rat.

It can be called 'rich and rich'.

Daily cultivation, with the help of spirit stones and spirit rice, Wutong Aoki Jue now only needs to cultivate for less than three hours a day to reach the limit.

Cultivating the alchemy technique, he can now swallow and refine two drops of demon beast essence blood in one day, and his cultivation speed has made a qualitative leap.

The stars are moving.

The night passed.

The next day, Su Yu woke up from his cultivation and stared intently at the words on the proficiency panel in front of him.

[Exercises: Sycamore Aoki Jue (2nd layer, proficiency 4.5%), Crocodile Demon 1008 Alchemy (3rd layer, proficiency 21.4%). 】

"In one day, the proficiency of Sycamore Aoki Jue can be increased by 0.18%, and the proficiency of alchemy can be increased by 0.82%." Su Yu was thoughtful.

In this case, it will take a year and a half for Sycamore Aoki Jue to break through the third layer.

The alchemy technique will take more than two months to break through to the fourth layer.

Swallowing two drops of the first-order mid-order demon beast essence blood cultivation in one day, the improvement speed of the alchemy technique is more than twice as fast as without resources.

Otherwise, it would be impossible for the alchemy technique to break through so quickly.

Subsequently, Su Yu tried to use the lower grade spirit stone to assist the cultivation of the Wutong Aoki Jue, and his cultivation speed was indeed greatly improved, and his proficiency could increase by 0.28% in one day.

If he used spirit stones to cultivate for a long time, it would only take him about a year to break through the third layer of the Qi Refining Realm.

"If you can have the assistance of Qi Refining Pill, your cultivation speed can be even faster, but a bottle of ten Qi Refining Pills requires ten lower-grade spirit stones, which is equivalent to one lower-grade spirit stone and one Qi Refining Pill."

"And for the early stage of Qi refining Realm, one Qi Refining Pill only has an aging period of two or three hours, compared to using spirit stones, it is still cost-effective to use spirit stones to cultivate."

Pity......

Su Yu shook his head, not only could he not take medicine now, but even the spirit stone could only be used to assist in cultivation every once in a while.

If you have more, you can't afford it.

Calculating the cultivation resources in his hand, Su Yu cultivated step by step every day, in addition to the task of the medicine field.

One night half a month later, Su Yu went out again to lay down five beast traps, and this time he hunted three ground rock rats, but they were all only first-order early demon beasts.

In addition to leaving the demon beast flesh and blood to relieve the cravings every day, leaving a little bit of the first-order early demon beast essence blood, Su Yu sold all the rest of the materials to the family, and once again received nine lower-grade spirit stones.

Time passed slowly.

Su Yu came to the medicine garden for two months.

In the past two months, the infestation of rock rats in the medicine garden has become more and more serious, which has affected the safety of the Su family medicine garden, and many elixirs have been bitten and destroyed by ground rock rats.

There were even more than a dozen ordinary clansmen who died under the minions of the ground rock rats.

This made the top of the Su family angry.

Determined to rid the Ground Rock of the Rats.

The head of the family, Su Peng, came to the medicine garden soon after, and announced a bounty task, anyone who hunts a first-order early ground rock rat will be rewarded with an additional five lower-grade spirit stones in addition to the value of the materials.

Hunt a mid-first-order ground rock rat and get an additional 20 lower-grade spirit stones!

Hunt a first-order late-stage ground rock rat and get an additional 100 lower-grade spirit stones!

Because the ground rat infestation in the medicine garden has reached the point where it will cause extinction if it is not cleaned up.

If the ground rock rat group was allowed to grow, even without the influence of the first-order spirit vein, their Su family's elixir business would not be able to do so.

Whether it's for the Medicine Garden or for the first-order spirit veins, the Earth Rock Rat Demon Group must be cleaned up.

Su Yu didn't know how the high-level family members viewed the possibility of a first-order spiritual vein in the medicine garden, and whether there were any preparations behind it.

But after the head of the family, Su Peng, announced the bounty task, Su Yu was very happy.

In the past month or so, he had only shot twice, but he had hunted five first-order pre-ground rock rat demon beasts.

If according to the family's current reward, even if he didn't buy materials, he would be able to earn a full twenty-five low-grade spirit stones.

I can scrape together enough money for half a low-grade magic weapon!

"Next, you can hunt more." Su Yu made a decision, even if the family noticed that he was very good at hunting ground rats, it didn't matter.

This time the family's bounty was enough for him to take a risk.

He looked at the belongings he had saved, and there were ten low-grade spirit stones.

He took them all out and bought a full fifty copies of the beast decoy powder materials.

Wait until the evening.

When Su Yu wanted to grind a few servings of beast trap powder and go out hunting, several of his senior brothers called him, planning to go to the medicine field together to ambush and hunt ground rats.

"Let's go together, many people have gone to the medicine field after dinner, and some people even plan to live in the medicine field." The eldest senior brother Su Minghuai warmly invited, and the other two senior brothers were also very interested.

The family's bounty made all the immortal cultivators in the medicine field red-eyed, and Su Yu was not the only one who was eyeing this cake.

Listening to what a few senior brothers said, Su Yu was stunned for a moment and almost miscalculated.

If so many people ambushed the ground rats, it was unlikely that he would succeed in trapping and hunting them.

There is even a high chance that the presence of animal decoy powder will be exposed.

Therefore, he can't go hunting for the time being.

"No, I'd better cultivate here in peace, I'm not strong." After thinking about it, Su Yu decided to avoid this craze, wait and wait, the Earth Rock Rat Demon Group is not so easy to deal with.

Therefore, he politely declined the invitation of the three senior brothers.

Turn your head back and continue practicing.

For the next period of time, the medicine field was very lively every night, countless immortal cultivators hibernated in the medicine field waiting for the ground rock rat to show up, once they appeared, they might be beaten by several, or even a dozen immortal cultivators.

This thing lasted until more than a month later, when the Earth Rock Rat Demon Group was hunted by nearly a hundred, and they didn't show up much, and the immortal cultivators in the medicine garden stopped slightly.

That night.

in the room.

"Whew! Call! Call! ”

Su Yu exuded an incomparably hot breath all over his body, and every breath he exhaled was as hot and red as a flame.

The blood and qi in the body are churning like a great river, and the thunder is rolling, and it is deafening.

At a certain moment, the blood qi in Su Yu's body reached its limit.

"Boom!"

"Roar!"

In an instant, the blood in the room was blazing, and Su Yu's whole body was shrouded in blood, like a sea of blood, the blood turned into a huge giant crocodile, entrenched on Su Yu's head, with teeth and claws, and pieces of blood-colored scale armor manifested, hideous and terrifying.

Raising his head and roaring, it shook Su Yu's Shenhai Spirit Platform, and on the Spirit Platform, a hazy figure sat cross-legged, calmly looking at the arrogant and domineering giant in front of him.

Blood-colored veins like scales appeared on the surface of Su Yu's body, and in an instant, Su Yu's body swelled a lot.

Like a giant crocodile in human form, his breath is violent and terrifying.

This time, Su Yu's body had undergone transformation for nearly half an hour, and the blood-colored veins on the surface and the violent blood qi on his body slowly restrained, and his body returned to its original appearance.

When Su Yu opened her eyes and looked intently at the proficiency panel, the words on them had already changed.

[Exercise: Crocodile Demon One Hundred and Eight Alchemy (Level 4, Proficiency 0.01%).] 】

At the fourth level of alchemy, his body and strength were no weaker than those of the mid-first order demon beasts.
