Although this spirit stone is only of inferior grade, the effect is nearly 8 times stronger than that of Zhu Guo, and it is definitely a good thing to improve the value of cultivation.

However, in terms of use, Zhu Guo is more convenient and can be eaten directly, while the spirit stone must be used during retreat and cultivation, and slowly absorbed.

As for how to retreat and cultivate, it is not clear that Feng Wuxian is not clear.

The so-called ship is naturally straight to the bridge, and when it comes to building the foundation, it is estimated that it will be known, so there is no trace of wind and others who are not worried about this at all.

After a small interlude, they began their journey to explore the path again.

The deeper you go to the "Spirit Milk Cave Heaven", the mist of the mist that is swirling around the spirit becomes more and more intense, and the visibility naturally decreases gradually.

Along the way, there were quite a lot of spirit stone mines, but it was always bad to trouble people, so Feng Wuxian was embarrassed to ask Lan Lan to continue to be a free coolie for them.

However, to his great surprise, she took the initiative to take on the task of collecting spirit stones without him making a silent request.

This makes Feng Wuxian both touched and gratified, it seems that NPC's friends are good, not to mention loyal, and very diligent.

At first, the four girls thought that Feng Wuxian had privately asked Lan Lan to do it, but they actually took turns to "crusade" against him on the team channel, saying that he abused child labor and bullied little girls.

Alas, he didn't swallow the spirit stone alone, they really got cheap and behaved, and all the good people were made by them, and he could only be the bad guy.

In fact, Feng Wuxian knew that they were joking on purpose, so he didn't explain much.

However, it is indeed a bit reluctant to let the cute and well-behaved Lan Lan give them things for free.

So, after Lan Lan collected a few times, Feng Wuji proposed: "Lan Lan, there are enough spirit stones, why don't you take a rest first." ”

"Brother Traceless, Lan Lan is not tired, Lan Lan wants to collect a lot of spirit stones for you, do you say Lan Lan is good to you?" Hua Ruolan smiled and shook her head, and suddenly said.

Hey? What's going on? Is it the effect of the intimacy being raised again?

Although he was surprised in his heart, Feng Wuxian immediately smiled and said, "Okay, of course it's good, Lan Lan is the best!" ”

"Since Lan Lan is so good, Brother Traceless, do you have any reward?" Lan Lan continued to coquettishly.

"Huh? So what reward do you want? "Is this still an NPC? Wind Without a Trace was immediately stunned.

"The reward, I haven't thought about it yet, but Lan Lan wants to ask, Brother Traceless, can you promise any reward?"

"This ......" Feng Wuxian immediately made a difficulty, she didn't say anything reward, how could he agree to come down, in case she said that she wanted the moon in the sky, then he couldn't satisfy her.

Seeing Feng Wuxian embarrassed, Hua Ruolan suddenly laughed and said: "Brother Wuxie, Lan Lan is joking with you, I don't want any rewards, people are willing to do it for you, and Lan Lan is practicing the collection technique, and she is about to be promoted to the advanced level." So Brother Traceless, you don't have to feel sorry at all. ”

Khan, he was actually tricked by this NPC little girl, she was coquettish just now, where does she still look like an NPC, it's just a naughty little sister next door.

"Haha......" Hearing that Feng Wuxian was fooled by Lan Lan, Xiaoya, Yiyi and Qingqing immediately laughed.

Even Xue Ting, who has always been generous and steady, couldn't help but cover her mouth and laugh.

They can laugh if they want to, who told him to fall for Lan Lan? However, being able to see Lan Lan's eccentric side is not in vain for him to be fooled.

……

Odd? Isn't there any monster in the Spirit Milk Cave Heaven? Or are they all hiding in a corner somewhere?

After carefully searching forward for more than 50 meters, although there is still a considerable distance from the end of the cave, everyone still feels a little incredible.

Judging from the elite monsters that suddenly ran out of the cave before entering the cave, there should obviously be a monster near the entrance of this Spirit Milk Cave, but now that they have been looking for so long, there seems to be no sign of a monster appearing, which inevitably makes them feel a trace of regret in their hearts.

Fortunately, the unexpected acquisition of a large number of spirit stones has made them gain something, and it is not worth the trip.

Moreover, according to Lan Lan, there should be more precious spiritual milk in this cave than spirit stones, so regret is regret, and their curiosity has not been affected at all.

The spirit stone is something that can only be used after the foundation is built, and after being allocated a few times, maybe it is troublesome, and the four girls said that they are not busy with the distribution, and they will all be released here without a trace.

It's okay to save trouble, anyway, when they need it, they will come to him to get it, so he readily agreed.

After Lan Lan collected more than 10 spirit stone mines, her collection technique was upgraded to the advanced level, and her level was also raised to level 22.

According to her, advanced collection techniques not only have a wider range of collection, but also significantly improve the quantity and quality of collection.

For example, it turns out that the Intermediate Gathering Technique can obtain 5 pieces of finished products by collecting a Primary Spirit Stone Mine, then the Advanced Gathering Technique is at least 6 pieces or more.

As he walked, the number of spirit stone mines in front of him suddenly decreased sharply, but Feng Wuxian clearly felt that the aura in these ores seemed to be more intense, and at the same time, the quality of the appearance had also been greatly improved.

Could it be a high-grade spirit stone mine? In addition to his surprise, he immediately used the Eye of the Stars on a nearby spirit stone mine.

[High-grade Spirit Stone Mine]: After collecting, you can obtain medium-grade and high-grade spirit stones, which consume 200 vitality points, and collecting this item requires the collector level to reach the advanced level.

Sure enough, it is a high-grade ore, but fortunately, Lan Lan's collection technique has been upgraded, otherwise he can only hope for Baoxing and sigh.

After discovering the high-grade ore, Lan Lan seemed more excited than Feng Wuji, and immediately rushed forward with a mine shovel.

"Ding...... After a few clicks of "Ding ......", the high-grade spirit stone mine immediately turned into a burst of white light and entered Lan Lan's Sumeru package.

At this time, Feng Wuxian suddenly saw a golden light falling from Lan Lan's body, and it seemed that she had upgraded again.

Hey, strange thing, didn't she just upgrade before? How......

When Feng Wuxian was puzzled, Lan Lan had already shouted in surprise: "Wow, Brother Wuxie, Lan Lan has been directly promoted by two levels, do you know what Lan Lan has collected?" ”

Feng Wuxian was immediately surprised: "What? You have directly upgraded by two levels, have you collected the best spirit stones? ”

Lan Lan smiled skillfully: "Brother Traceless is really smart, you guessed it right, it is the best spirit stone." ”

After Lan Lan finished speaking, he immediately traded the spirit stones he had just collected to Feng Wuxi.

System Prompt: Transaction Successful! You have obtained × 1 medium-grade spirit stone, 1 high-grade spirit stone, and 1 top-grade spirit stone× and ×1 top-grade spirit stone.

[Medium-grade Spirit Stone]: Used for retreat cultivation, after absorption, the cultivation value is increased to 20,000, and it can be used after the cultivation realm reaches the heartbeat.

[Top-grade Spirit Stone]: Used for retreat cultivation, after absorption, the cultivation value is increased to 100,000, and it can be used after the cultivation realm reaches the Yuan Infant.

[Best Spirit Stone]: Used for retreat cultivation, after absorption, increase the cultivation value to 1,000,000, and can be used after the cultivation realm reaches the distraction.

……

Seeing the attributes of the top-grade spirit stone, Feng Wuxian was immediately shocked, a small spirit stone could actually increase the cultivation value by 1 million, compared to the lower-grade spirit stone that could only increase the cultivation value by 5,000, the effect was increased by 200 times.

The only fly in the ointment is that the cultivation realm required to be used by the best spirit stone is distraction, and this realm is already a fairly advanced realm, and it is definitely not something that can be achieved in a short period of time.

It seems that if you want to use this kind of good thing, you have to go through long-term and unremitting efforts.

When the four girls heard Lan Lan's cheers, they had already gathered around curiously.

After learning that they had dug up the best spirit stones, they couldn't help but be very excited, and praised Lan Lan's awesomeness.

While Lan Lan was overjoyed, she shyly said that this was all luck, and she never thought that she would be able to dig up the best spirit stones that only grandmaster-level collection techniques could dig with her advanced collection skills.

However, the best spirit stones are not so easy to pick, and the corresponding price paid by Lan Lan is that the vitality value is all used up at one time, and she needs to rest for a long time to fully recover.

According to Lan Lan, her current vitality value can recover 24 points per minute, and if she wants to continue digging the next high-grade spirit stone mine, she will have to wait for almost 10 minutes.

(Note: When leveling up, only the upper limit of vitality value will be increased, and the lost vitality value will not be restored.) ）

Being able to get so many spirit stones unexpectedly is no less than pie in the sky for them, so Feng Wuxian hurriedly said, "Lan Lan, then you can rest well and recover your vitality value." ”

Lan Lan nodded obediently and gently: "Well, Brother Traceless, when Lan Lan recovers, I will collect more spirit stones for you." ”

"Silly brother, why is Lan Lan so good to you, Yiyi is a little jealous."

In the team channel, Yiyi suddenly joked with a smile.

Immediately afterwards, Xiao Ya also smiled and echoed: "Yes, stinky rascal, people are also jealous, you give us an honest explanation, what kind of confused soup did you pour into Lan Lan, how can she be so good to you, listen to you so much." ”

Although Qingqing and Xue Ting didn't say anything, the expressions on their faces undoubtedly showed that they also wanted to know what was going on.

I didn't tell the four girls about the increase in intimacy with Lan Lan before, but now that they asked, Feng Wuxian didn't hide it much and told them.

Hearing about the intimacy, the three girls immediately felt extremely surprised, only Qingqing seemed to have heard about it, and did not feel particularly surprised.

Moreover, Qingqing also mentioned to us the inside information of intimacy.

"It is said that in the wilderness, every NPC has a high level of intelligence, once the intimacy with a player reaches 100, then this NPC will be out of the control of the system and become an existence similar to a real player, with its own independent emotions and ways of thinking."

"Is this true? It's amazing! Feng Wuji immediately felt very shocked, and at the same time, his heart was full of anticipation.

"Is that okay? Stinky rascal, then you must not have any bad thoughts about Lan Lan in the future! Xiaoya's face seemed a little angry.

"......" Feng Wuxian fainted secretly, which nerve did she take wrong, she even had to take care of an NPC, she was really speechless, you can't afford to hurt the girl who came to your relatives.

"Sister Xiaoya, aren't you? Oh, I see, you're scared ......."

"Yiyi, how can there be!" Xiao Ya was ashamed, and hurriedly interrupted Yiyi's words and said, "I'm not worried that Lanlan sheep will fall into the tiger's mouth." ”

Unrelenting, Yiyi continued to quip: "Worried about Lanlan? Sister Xiaoya, I think you're worried about yourself, hehe......"

Xiaoya was immediately embarrassed, and said angrily: "Okay, stinky Yiyi, you have itchy skin, right, my sister will teach you a good lesson today." ”

"Come on, Sister Xiaoya, who's afraid of whom."

"Okay, then you wait, I must make you look good today."

Immediately after that, they chased each other and tickled each other.

The sense of touch in the "Haha......" game seems to be very sensitive, and the feeling of tickling is not reduced at all.

"Haha...... Sister Xiaoya spared her life, Yiyi didn't dare anymore. ”

It seems that Yiyi's senses in the game are more sensitive, so she is more afraid of itching, so it didn't take long for her to lose the battle and beg for mercy.
