The territory of the level 10 fierce beast was a little different from what he imagined.

Perhaps, it was because the previous fierce beast territory was relatively peaceful, which made Xu Yi a little overconfident.

I feel that it is easy to hunt a level 9 beast, so entering level 10 should be the same.

It turned out that Xu Yi was too simple.

The territory of a level 10 fierce beast is countless times more fierce than that of a level 9 beast.

He felt that if there was no level 10, it would be better not to rush into the territory of the level 10 beast.

"Xu Yi, did something happen?" Lu Ke also ended his cultivation and came to Xu Yi's side.

Xu Yi glanced at Lu Ke, and then said, "There are still flying fierce beasts active over there in the level 10 fierce beast territory, and our drones have all been destroyed. So, before we reach level 10, it's better to be cautious. ”

"Well, Xu Yi, you said that after those fierce beast rats finished eating the fierce beasts, the brain crystals should be left behind, we should be able to pick up the brain crystals, right?" Lu Ke thought that since he couldn't get by, then there would be no problem with cultivating well at level 9.

"Chances are they're not paying attention, and we'll go and take a look at the bones in a moment. Xu Yi was also suspicious, after all, brain crystals could not be eaten, and there was no way to kill beasts.

At present, Xu Yi has seen something that can be absorbed, that is, a psychedelic flower beast.

However, the effect of absorbing brain crystals is still not as good as absorbing **, so snails don't like to absorb the mental power in brain crystals.

Xu Yi continued to check the video, and then walked out of the tent with Lu Ke.

The two of them came to the vicinity of the junction, and then used their spiritual power to move the skeleton in the distance out.

Then, Xu Yi found that the head of the beast's remains was intact and had not been bitten open.

Brain Crystal, it's inside.

After smashing it open, Xu Yi got the brain crystal inside.

"Rich, Xu Yi, we are rich. Lu Ke said happily, the brain crystal is already a currency. Anyway, Yimen is going to use Brain Crystals as a currency.

Precious metals no longer have any meaning, valuable metals are those that can be used to make weapons, metals that make all kinds of utensils.

Gold, silver, and the like have lost their usefulness.

At least in Xu Yi's view, there is no value to Yimen.

But the brain crystal is different, it can not only be used on the star gate, but also in the portable energy reactor, and it is also used by mages and divine masters to fight.

Especially on the premise that your mental and mental power is exhausted, you can use it to fight or escape.

Such a thing is very useful and reasonable as a currency.

"It seems that our next task is to collect brain crystals. It would be a waste if you didn't collect so many brain crystals. I don't think it seems necessary for those beast rats to die now. Xu Yi said while controlling the remains on the opposite side to fly over.

After all, it takes time to hunt fierce beasts, and if you can pick up brain crystals like this, it will save a lot of time and energy.

"Well, I also think it's good, it saves time and effort. Lu Ke also agreed with Xu Yi's idea, those fierce beast rats could be kept for the time being.

Anyway, if others want to break through to level 9 now, it will take a long time.

Maybe when the others break through to level 9, Xu Yi and himself may be level 11, or stronger. At that time, if there is a need, these fierce beast rats can be easily dealt with.

The two of them kept picking up, and by the time it got dark, they had already picked up more than 600 pieces.

If it weren't for the three encounters of level 9 fierce beasts, after fighting for a while, they could still pick up some more.

In the evening, two men lit a fire outside the tent.

The meat of the level 9 peak beast, when grilled, is very fragrant.

Especially now that there are various seasonings, the fragrance is even stronger.

"Xu Yi, you said that those fierce beast rats smelled the smell, would they rush directly towards us?" Lu Ke asked with some concern, after all, among those fierce beast rats, there were at least 3 and 10 levels.

"Probably not, they don't have much guts. Xu Yi felt that they should only dare to stay in the misty area, once they left, the birds and beasts in the air would be their natural enemies.

Xu Yi had observed before, as long as there was a slight situation or noise in the depths of the fog, they would return to their nests as soon as possible.

Therefore, they should be very afraid of exposing themselves to the fog zone.

In fact, Xu Yi's guess was completely correct, those fierce beasts and rats didn't dare to leave the misty area at all. Once they leave, they become food for birds and beasts.

After all, their strength is still relatively weak, and they mainly rely on their own fierce beast aura to scare the level 9 peak fierce beasts.

If you can't be frightened, most of those are just some injuries and just rush out of the fog area.

Of course, just because you're safe through the Fog doesn't mean you're safe.

Those birds and beasts in the sky, as well as other level 10 beasts on the ground, will also attack them.

After all, if you hunt a level 10 beast, they may turn it into food themselves, but it is very easy to hunt a level 9 peak beast.

After the two of them finished eating the barbecue, none of the fierce beasts and rats appeared.

However, there were two level 9 peak beasts.

Now, they didn't have much trouble dealing with level 9 peak beasts, and if they combined with the Spirit Devourer, it would only take ten minutes to solve it.

After getting rid of the two beasts and disposing of them, the two took turns to take a bath.

Then, I continued to cultivate.

Xu Yi turned on the spiritual vision, and also turned on the invisible function of the tent.

The night passed quickly.

This night, it was still very peaceful.

Because their camp was full of bones, even if a beast came nearby, it quickly left.

In the next time, Xu Yi and Lu Ke both picked up brain crystals during the day and cultivated at night.

For them, using spiritual power to carry objects can also be regarded as a kind of cultivation, but the efficiency will be relatively much lower.

However, you can get brain crystals.

Because of the relationship between the cultivation of "Taixuan Jue", the progress of the two people is still very fast.

By the time Xu Yi had clocked in for 588 days, the two of them had already reached the peak of level 9.

Tomorrow will be Xu Yi's 589 days of punching in.

With such a speed, it is already considered fast. At least, it has completely exceeded Xu Yi's expectations.

After the check-in was over, Xu Yi was ready to use the level 10 perception to let himself break through to level 10 first, and then use the previous method to let Lu Ke also break through to level 10.

When they have level 10 strength, then they can sweep away the remaining beast skulls and take out the brain crystals inside.

During this time, they had already picked up more than 6,000 brain crystals of level 9 fierce beasts.

A level 9 fierce beast's brain crystal can allow 1,000 people to enter the Spirit Blue Star, and they can let more than six million people enter the Spirit Blue Star here.

Therefore, the role played by the brain crystal of a high-level fierce beast is much more powerful than that of a low-level fierce beast brain crystal.

This time, Xu Yi and Lu Ke really earned it.

There shouldn't be much brain crystal left, and it shouldn't be more than a thousand at most.

It can only be said that those fierce beast rats are also strong enough, and they actually ate seven or eight thousand level 9 peak fierce beasts.

I don't know how long they've been here.

Time, in a blink of an eye, it is time to check in for 19 months.

"Ding, check in for 31 days, or an intermediate pack. ”

After a month, the voice sounded again.

For Xu Yi, this voice is always so pleasant.

Even if it doesn't have any emotion at all.

"System, open the package. ”

Xu Yi was curious about what kind of gift package he would get this time.

Isn't there storage space and pet space?

"Ding, gain Mental Power Booster*2 (Intermediate)"

"Ding, obtain a Mental Power Stimulation Elixir*1 [There is a 75% chance that the mage used will awaken mental power, which is a precious elixir and is suitable for the most loyal companions] (Intermediate level). ”

"Ding, get a fast-acting body repair potion*3 (intermediate). ”

"Ding, get the secret technique - Ice Arrow Shot (Intermediate). ”

Xu Yi couldn't help but show a smile, it was completely different from the gift package of the previous month.

This month's gift package is too powerful and too pleasantly surprised.

The mid-level spiritual power boosting potion still has some effect on them.

Especially if they start using it after their realm has been upgraded to level 10, they can save a lot of time when they reach the peak of 10.

There is also an intermediate level of the spiritual power stimulation potion, and the probability has also increased to 75%, and the success rate is even higher, a full 15 points.

With this potion, other Yimen high-level leaders who can't awaken their spiritual power will have a chance to awaken their spiritual power.

Xu Yi now especially hopes that there will be a few more such elixirs.

Cheng Jie, Liu Li, Zhou Zhou, Zhou Chun, Qin Yue, the five of them haven't awakened their spiritual power yet.

As the core figure of Yimen, if he can awaken his spiritual power, he is naturally the best.

Although there are 108 people in the God of War Temple, Xu Yi doesn't have much affection for them.

Only when they fight side by side in the future can they have a friendship of steel.

Fast-acting body repair agent, this junior Xu Yi still has some left, but he didn't expect that this time the system gave 3 more. Xu Yi felt that the primary ones were already very powerful, so the effect of the intermediate level was estimated to be very rebellious.

This thing is definitely a life-saving elixir.

The last one, the secret technique, is frozen.

Now, Xu Yi already has several secret skills, Ice Arrow, Ice, Flame, and Spirit Blade.

Among them, there are already two related to ice.

The spiritual blade, Xu Yi has rarely used it.

Because, this effect on mages and fierce beasts is still relatively small, it is mainly aimed at divine masters, as well as demon clans who awaken spiritual power.

The other Xu Yi has already mastered is the explosion of flames, and as for the frozen Xu Yi, he has not yet gone to cultivate.

But this time, Xu Yi felt that he could start cultivating and use these secret techniques.

Naturally, Lu Ke also needs to be taught to cultivate.

"System, accept the package. ”

After finishing speaking, countless messages poured into Xu Yi's mind.

Now as his mental power became more and more powerful, the speed of information transmission was faster, the reaction was smaller, and he almost didn't feel any stinging sensation.

After receiving it, Xu Yi opened his eyes.

Lu Ke was still cultivating there, and he didn't find anything unusual.

Xu Yi stood up, walked outside, and went to prepare breakfast.

Once he had eaten, he began to use the 10 Insight Pack.

When Xu Yi started cooking, Lu Ke finished his cultivation.

After the two of them had breakfast and chatted a few words, Xu Yi asked Lu Ke to be in charge of guarding.

He uses the level 10 Perception Pack himself, so it's better not to be disturbed.

If you are disturbed and you can't break through to level 10, it will be a waste of a precious Insight Pack.

So, Lu Ke stood guard not far from the tent, forbidding all the fierce beasts to disturb Xu Yi.

She also knew that Xu Yi was preparing to hit level 10.

In fact, Lu Ke was even more nervous than Xu Yi.

Because she remembered that the Spirit Race had spoken about human talents and bottlenecks.

If they spawn Brain Crystals when they break through to level 10, it means that they will most likely stop at level 15.

Level 15?

This strength is completely unable to compete with the Jialan civilization.

During this time, Xu Yi also mentioned Jialan Civilization, saying that the "Awakening Formula" given by Jialan Civilization will continuously release brainwave signals, and the signal bands sent by everyone are the same.

The more people who cultivate, the stronger the signal will be, and the easier it will be to reveal one's position.

Therefore, Lu Ke felt that if they didn't generate brain crystals, then their bottleneck might be after level 20.

When you reach level 20, your strength should be quite strong.

Time passed slowly, and Lu Ke's heart became more and more nervous.

Suddenly, she felt a powerful aura.

Breakthrough!

Judging from past experience, Xu Yi made a successful breakthrough.

It took three hours, which is extremely fast.

Then, a mist of aura began to develop near the camp.

After another hour, this aura fog dissipated, and then Xu Yi walked out of the tent.

"Xu Yi, congratulations on the promotion. How is it, have you generated brain crystals?" Lu Ke asked directly, after all, she didn't need to make any detours with Xu Yi, she could ask directly.

"Without generating brain crystals, our potential is still good. Xu Yi smiled slightly, he had also worried about this problem before the impact.

"Great!" Lu Ke said happily, and then took out the stove.

It was already noon, and she and Xu Yi were a little hungry.

The stronger the strength, the more energy is consumed.

If you don't eat for more than a certain amount of time, your body will start to break down your energy. In this way, it can be maintained for more than ten days without starvation, and the strength will gradually decline, or even fade.

But why should they starve to burn their energy when they can eat?

After boiling a large pot of ferocious beast meat, the two of them had a full meal.

After eating, Xu Yi and Lu Ke rested for a while, and then changed to a new position.

In the process of moving, Xu Yi used his spiritual power to seal the breath of the two people, so that there would be no smell left, so that the fierce beast could find it.

Because, next, Xu Yi wants to share his 10 breakthrough insights, so that Lu Ke can also break through to 10 divine masters.
