At five o'clock in the afternoon, only Lin Fan was left with Su Dai, and the other three went to study with Han Ruxin.

The three of them are already dizzy. They have learned too much at once and cannot digest it at all. Now they need to practice it on their own.

Because of Lin Fan's presence, their progress was greatly advanced.

Su Dai was still frantically delivering a lot of knowledge to Lin Fan, as if she wanted to complete the teaching at once.

Lin Fan has been studying in an orderly manner, starting from the beginning and slowly starting to see more.

At the same time, he also realized something. Researchers originally existed to study innate skills, and many of today's martial arts were derived from innate skills, and later gradually turned into techniques.

In particular, some melee moves, such as horizontal slash, cross slash, storm slash, etc., are all derived from natural skills and gradually transformed into ordinary skills.

And the ultimate trick of "Thunder God-Slaying Technique" was actually born out of a natural skill at the beginning!

magic!

Incredible!

This opened Lin Fan's eyes.

In the evening, Fang Yan brought dinner. Fang Yan cooked it by herself and ordered fresh vegetables to be delivered to her door. It must be said that Fang Yan's cooking skills are still very good.

Su Dai even said: "From now on, you will be in charge of dinner."

This made Fang Yan extremely happy.

You know what Su Dai said, you can let her stay and continue studying.

Studying here is completely different from other places. She can discuss with Gu Ying and Yan Yan, and she can learn faster. What's more, there is Su Dai's teaching. Even if they are just watching, their teaching and vision are not the same.

Grade.

After all, Su Dai is a senior researcher, while Han Ruxin is only a mid-level researcher, and in this learning environment, the pressure is completely different, which makes her level of effort completely different.

It wasn't until ten o'clock in the night that Lin Fan left Jiuxuan Mountain in a daze. He also felt that his energy was a little insufficient. After all, he had concentrated on studying all afternoon. Su Dai hardly allowed him to rest and kept pouring out knowledge desperately.

.

Gu Ying and the other two were exhausted. They had already started at five o'clock, and they were already completely unable to keep up.

Although it is tiring, such a life is fulfilling.

Before leaving, Lin Fan still remembered to ask about Su Yiliu's address and his phone number.

When Lin Fan returned to the apartment, Guo Zhen had been waiting for a long time and came immediately. This time he delivered a total of 300 drops of second-grade blood essence.

But only sixty drops were delivered the day before yesterday!

This made Lin Fan call him a good guy!

Lin Fan took out the essence and blood he extracted today, threw it to Guo Zhen, and said, "Swallow it and see!"

Su Dai not only taught Lin Fan today the method of extracting first-grade blood essence, but also the second-grade blood essence and third-grade blood essence. After all, Lin Fan is now third-grade and five-star. In Su Dai's opinion, a large amount of third-grade blood essence is needed.

You can save money by buying some rough third-grade blood essence and well-made third-grade blood essence yourself.

In the end, Su Dai also confiscated how much money Lin Fan had. The wasted and finished blood essence was priced at half the market price, and the prepared blood essence was thrown away to Lin Fan himself.

Guo Zhen looked at the blood essence in his hand, glanced at it, and said, "It seems to be better looking than the ones exchanged at the school."

Then throw it directly into your mouth!

Lin Fan asked Guo Zhen to swallow it, so he naturally wanted to see the effect. Guo Zhen had been practicing by swallowing blood essence, so that the feeling would be obvious.

If the effect is good, when the time comes to practice, I can become proficient in the operation, and at the same time I can make a batch of such blood essence for Guo Zhen and others, which can quickly improve their strength.

And soon, five minutes later, Guo Zhen opened his eyes and said with a shocked expression: "Brother Fan, how did you get this essence and blood? It is tamer than the fine blood essence and blood provided by the academy! Although it is only the first-level essence and blood, it is

The absorption can even catch up with the second-grade blood essence. With this kind of blood essence, I can definitely open a node again in two days!"

Lin Fan smiled and said nothing, and threw him another drop of second-grade blood essence.

Guo Zhen's eyes flashed. He didn't even bother to say anything this time and just threw it into his mouth.

Six minutes!

Guo Zhen's face suddenly became serious, and at the same time, a powerful force appeared from inside his body and dispersed in all directions. It was the weak wind pressure caused by the unconscious star power emitted from the body.

At the same time, this also means that Guo Zhen has completed a node in a short period of time, and his strength has broken through to the second level and three stars.

But it was not over. After another four minutes, Guo Zhen opened his eyes, his eyes full of excitement and shouted: "Brother Fan, this blood essence is awesome! It is similar to the drop of first-grade blood essence just now.

The same feeling, but this is the second-grade blood essence, and this drop of second-grade blood essence has directly opened a node for me, and it is also stable! It is absorbed so smoothly, and it is much stronger than the second-grade blood essence exchanged by the school.

There are too many, and the market is even more bullshit. Comparing it, walking becomes like flying iron!

Wardian! It’s incredible! If I had this kind of essence and blood, my node opening speed would definitely be increased by three times, or even more.”

But after saying that, Guo Zhen looked lonely again, "Hey~ I'm too greedy. This kind of blood must be hard to come by."

Hearing Guo Zhen's words, Lin Fan almost laughed out loud.

"Haha, it's okay. This kind of blood essence is easy to get." Lin Fan said with a smile.

When Guo Zhen heard this, he immediately raised his head, his little eyes widened, and immediately grabbed Lin Fan's hands, "Brother Fan, you are my brother! If you have this channel, I will buy a drop.

40,000 yuan! If there is a large supply of goods and a stable channel can be provided, I can supply it through my channels, and it can be anything from 50,000 yuan to a drop."

"We definitely don't have a large quantity, and we don't have a stable supply."

Lin Fan shook his head and said: "I really don't have time, so I can provide you with some training."

Guo Zhen suddenly looked disappointed.

This is definitely a good deal!

And it’s something that will definitely drive those geniuses and monsters crazy.

If this thing could be supplied in large quantities, he could immediately involve most of the people in the school into his channels.

What a pity!

Come to think of it, how can this kind of top-quality blood essence be supplied in large quantities?

If there were blood essence of this quality, the progress of freshmen in the entire school could be greatly improved!

Suddenly, Guo Zhen's eyes widened and he turned to look at Lin Fan with a look of shock on his face, "Brother Fan, what did you just say???? You don't have time?

??”

Hiss~

Guo Zhen seemed to have thought of something. He took a breath and trembled as he spoke, "Could...this is you..."

Guo Zhen pointed to his mouth and then to Lin Fan, asking if the essence and blood he had just swallowed was made by Lin Fan?

Lin Fan nodded.

Guo Zhen was completely stunned!

He never expected that this kind of essence and blood was actually made by Lin Fan, which really shocked him.

This made him feel a little incredible!

This quality of blood essence is much better than the high-quality blood essence provided by Jiutian Academy, the number one academy in mankind. The absorption efficiency is completely different, and even the sense of conflict is weak, so you can take more every day.

If you think about it, this kind of medicine has high absorption efficiency, quick opening, and you can take more.

This kind of cultivation speed can completely pull down other people!

This is also the reason why Guo Zhen just said that this kind of essence and blood is not easy to come by, because in the concept, this kind of essence and blood cannot be easy to come by.

And now Lin Fan said that this blood essence was made by him!!!

He would never have imagined it.

It was impossible for him to even think about it.

Lin Fan said with a smile: "Tomorrow, I will provide you with a batch of these second-grade blood essences. Well, then you and Miaotong will be divided into Tiancheng. They don't seem to have the second-grade yet. You tell them to hurry up. By the way,

Fan Jianyuan also gets some points."

"Okay, Brother Fan, I understand."

When he left, Guo Zhen was excited in his heart. Sure enough, he felt so comfortable hugging Brother Fan's thigh.

He naturally also knew who Lin Fan learned this technique from, naturally he learned it from the sixth-grade master Su Dai. Sure enough, what was exposed between the fingers of a strong person was intimidating to ordinary awakened people, and it was not a level that they could come into contact with.

And technology is only in the hands of a few.

Although this is just the introductory basis for Su Dai to teach Lin Fan, it contains the crystallization of Su Dai's decades of experience, and it is difficult for ordinary people to get started, and Su Dai will not specialize in teaching other researchers.

What flows to the public is the most suitable for production and automation, and is the product of generalization.

There is no way around this, after all, some things are not suitable for popularization.

Guo Zhen left, and Lin Fan touched the batch of second-grade blood essence sent by Guo Zhen.

"A large amount of energy has been detected, is it converted into star power points?" The system voice immediately sounded.

"yes!"

In a moment, three hundred drops of blood essence disappeared.
