Li Ling never expected that the Heavenly Thunder Regiment would be so sincere and invite him five times, which was beyond Li Ling's expectations, but Li Ling could be regarded as having clearly seen the true purpose of the Heavenly Thunder Regiment, the Heavenly Thunder Regiment was currently in short supply, and the red-eyed crystal beast that was rare to see in a thousand years appeared at this moment, which made the Heavenly Thunder Regiment so thirsty for talent.

Sadly, Hei Lin refused the other party's kind invitation five times in a row, which made the face of the Tianlei Group completely unbearable, and it is estimated that if he meets someone from the Tianlei Group in the future, neither of them will have a good temper.

"You've been in retreat for two months, but have you been able to refine anything?" Hei Lin was also very curious about what kind of elixir Li Ling had come up with in this two-month retreat, without eating or drinking, just a one-minded retreat alchemy.

"Oh...... The pill I refined this time is very good, it is a major breakthrough on my alchemy path, and I can finally refine the Heavenly Pill. Li Ling said this, but completely forgot about the disappointment.

"Tiandan?" Hei Lin didn't understand alchemy, and he didn't know what the Dao Heavenly Pill meant.

"Tiandan is the biggest gateway for an alchemist to mature, and if you enter this mouth, you can really count yourself as a qualified alchemist." Li Ling couldn't hide the joy in his heart and said with a smile.

"Listening to what you say, it seems that this Tiandan should be very powerful." Hei Lin asked.

The second baby was also fascinated by listening and very interested.

"Well, the medicinal value of Tiandan is much higher than that of Didan, and the medicinal value of a low-grade Tiandan is more than ten times higher than that of a high-grade Didan." Li Ling only calculated a multiple.

"It's a bit abstract and incomprehensible." Hei Lin shook his head slowly.

"Let's put it this way. If I let you eat this Tiandan-level Muscle and Bone Pill now, your Muscle and Bone Strength can instantly increase by one level and reach the strength of the Celestial Venerable. Li Ling said without joking at all.

Hei Lin couldn't help but beat his heart faster. Eating this Bone and Muscle Pill can instantly increase to the strength that can accommodate the Lower City Domain's supreme-level cosmic power.

"It seems that you have understood, now you understand how powerful Tiandan is." Li Ling smiled confidently.

"Understood...... I understand, if you can refine more such a Heavenly Pill, then wouldn't it, you and I will soon be able to reach the level of the county region. Hei Lin didn't dare to say much. I only dare to say that the level of the county.

"In the case of the Tendan, there is a tendon that forges the muscles and bones to the county level, but. It is only limited to the level of the county scholar, if you still want to go up, then you must refine a medium-grade Tiandan, or even a higher-level pill. Li Ling felt very excited when he thought about it.

"That'...... So how can we refine a higher-level elixir? Hei Lin said in a daze. After all, because of the simplicity of this news, it is too hot. That's great.

"High-grade medicinal materials, high-level alchemy strength, high-quality Dan furnace." Li Ling said three highs.

"High-grade medicinal herbs? Are things like dragon whiskers and dragon silk also considered medicinal herbs? Hei Lin asked.

"Count...... Muscles and bones are very important, and the general muscles and bones are the most important part of the muscles and bones. Li Ling replied.

"However, if it is a refining auxiliary, such as a medicinal herb that replenishes qi and blood, then the musculoskeletal herbs can only be used as auxiliary medicinal materials, and the ordinary positive herbs have become the main medicine." Li Ling added.

In fact. What kind of medicinal materials are more important in alchemy, and medicinal materials are divided into positive medicinal materials. Negative medicinal materials, neutral medicinal materials, musculoskeletal medicinal materials, five element attribute medicinal materials, etc...... There are many types of herbs that cannot be distinguished.

Li Ling is just on the edge of alchemy, if you want to continue to deepen, you still need to work harder, to be able to master the profession of alchemy, whether it is cultivation or auxiliary, you will get great benefits.

And the alchemist is like a key to the precious treasure house of the world.

"I'm dizzy when I hear it, I don't understand what you're talking about." Hei Lin shrugged helplessly.

"Eun, I don't understand either." The second baby also shook her head like a rattle.

"Ha Lu Ha...... It doesn't matter if you don't understand, just know how to take the pill. Li Ling said with a smile, and then said: "Hei Lin, the Heavenly Pill-level Muscle and Bone Pill refined this time is for you to take, you are now stuck at the peak of the Saint-level in the City Domain, and you can't break through without relying on the pill." Li Ling took out the Heavenly Dan-level Bone Pill from the space magic weapon.

It was a brown-gold elixir, and as soon as it came out of the space magic weapon, the air was filled with an elegant danxiang, which was shocking.

"Is this round bead an elixir? I was energized just by smelling it. What a magical thing, what a magical smell. Erwa took a deep breath and enjoyed it.

Li Ling picked up Hei Lin's hand, put the Tiandan-level Muscle and Bone Pill in the palm of Hei Lin's hand, and said with a slight smile: "Take it and try it first." ”

Hei Lin looked at the brown-gold Tiandan in the palm of his hand, and said gratefully: "Thank you, Li Ling." ”

"What's polite with me, everyone is a good buddy." Li Ling patted Hei Lin's shoulder and smiled arrogantly.

Hei Lin squeezed the pill tightly, flattened his mouth, and slapped Li Ling's arm away with his other hand angrily and said, "Who is a good buddy with you, I'm a girl, okay?" ”

"Ha Luha, I didn't expect Hei Lin to realize that you were a girl." Li Ling said teasingly.

Hei Lin was still a little grateful, but he was not lightly angry, and stomped his feet and said: "I was originally a girl, but I am a little stronger than other girls." ”

"Hey, you're so strong, it's a little bit." Li Ling said teasingly.

The second baby defended Hei Lin: "Sister Hei Lin is indeed a girl, but she is the kind of girl who is a little manly." ”

"Oh, yes, woman." Li Ling gave a thumbs up.

Hei Lin knew that he couldn't fight Li Ling verbally, so he had to be silent, took the Tiantian Pill angrily, turned around and went to his house to administer medicine.

Looking at Hei Lin's back, Li Ling felt very cordial, and had a feeling of being very trustworthy with such a friend.

"Erwa, you say, is your sister Heilin beautiful?" Li Ling squatted down and asked Erwa at the stall where Hei Lin was not there.

Erwa replied without hesitation: "Beautiful, but, Brother Li Ling, Sister Hei Lin is so beautiful, Brother Li Ling, why do you have to fight with Sister Hei Lin every time?" I've heard that girls who are generally beautiful should be loved by boys. ”

"People are small and big, who taught you this." Li Ling patted the second baby's head.

"I realized it myself." The second baby said with a smile.

"Hah, you kid." Li Ling was very surprised.

"Erwa, you go to accompany Huolin Deer to play first, and I'll go to see your sister Heilin taking medicine, you need someone to take care of it when taking medicine." Li Ling smiled at the second baby.

"Okay, I'll play with the deer." The second baby was obedient and went to play with the fire deer that was grazing in the yard.

Li Ling turned around and walked towards Hei Lin's room, came to the door, Li Ling knocked on the door, after a while, the door creaked open, Hei Lin saw that it was Li Ling, so he opened the door and said, "Come in." ”

Li Ling entered Hei Lin's room, although everyone lived in the same mansion, but Li Ling had never entered Hei Lin's room, as soon as Li Ling entered Hei Lin's room, he saw neat decorations and furniture, which were placed in an orderly manner, and it was really a woman's boudoir.

"It's nicely furnished, and when I come to your room, I think you look like a girl." Li Ling smiled.

"Hey, can you stop taunting me like that? I can't stand you saying I'm like a boy. Hei Lin sighed slightly.

"Okay, for the sake of your troubles, I'll improve the statement next time, but you have to take the Tiandan, and I'll take the medicine for you on the side." Li Ling said with a smile.

"Medicine, why haven't you heard of it before?" Hei Lin said strangely.

"The general Didan has a relatively small medicinal effect and is easy to be borne by the body, so you can withstand the medicinal power only by relying on your own physique, but Tiandan is different, the medicinal power will be ten times that of Didan, your small body may not be able to bear it, if I don't give you the medicine, you are likely to be unable to withstand the medicinal power and faint." Li Ling is definitely not alarmist.

"Look at what you said so terrifyingly, can the pill enter the stomach and still corrode the stomach?" Hei Lin said.

"That's not it, if the medicinal effect is too strong, if the medicinal power is not reconciled with true qi, it is likely to cause an imbalance in the power of yin and yang in the body, either the sun or the yin, and eventually the seven holes bleed." Li Ling said. (To be continued......)
