Chapter 662

As for another secret skill, ice arrows are fired at once. Xu Yi thinks it will be easier to learn after learning ice first.

Soon, they met a level 10 fierce beast.

"Lu Ke, you can use the explosive fire, and I'll protect you." Xu Yi thinks that Lu Ke should use the explosive fire first. After all, this secret skill also needs continuous practice, and then he can gradually master it.

Lu Ke nodded and immediately greeted the level 10 fierce beast.

This is the first time she used this secret skill. Although she controlled it carefully, it still took away half of her mental power in an instant.

The level 10 beast was surrounded by fire before it launched an attack.

The scream of the fierce beast was very sad and shrill. It seemed to seep in.

But within a few minutes, the cry stopped.

Together, there is fire.

The bodies of the fierce beasts are gone, leaving a mass of ashes.

Inside the ashes, there is a red thing.

Naojing, like Xu Yi, recognized it, but unexpectedly, it was burned red.

"Is this secret skill too powerful?" Lu Ke couldn't believe her eyes. Although she knew that the secret skill was very powerful, she didn't expect to be so terrible.

Level 10 fierce beast, burned to ashes in a few minutes?

Although such a secret skill is powerful and its effect is explosive, the corpses of fierce animals are burned away.

The meat of fierce animals is the source of food for them.

If they don't eat meat, they can't get enough energy at all.

Therefore, Lu Ke and Xu Yi don't think the secret technique of directly burning the fierce beast to ashes is a good secret technique.

This secret skill can only be used when making a quick decision.

After all, compared with martial arts, this effect is very direct. The fierce beast will be burned to ashes in a few minutes. People who use secret skills in this process will not have any signs of injury.

And Lu Ke felt that he didn't need half of his mental power. Controlling the mental power at 34% was enough to burn a fierce beast of the same level.

Those who are one level higher than their own strength should use 50% or 60% of their spiritual strength, and they should be burned to ashes.

"Restore your mental strength. We'll continue to look for fierce animals and try the secret technique of freezing." Xu Yi and Lu Ke said, and then controlled the red brain crystal to fly to the sky with mental strength.

In this way, in case of explosion, Lu Ke will not be hurt.

Flame is burning. Therefore, Xu Yi is quite satisfied with the result.

This, if used against other civilizations, is a very practical and powerful means of attack.

After all, it is impossible for humans to eat the bodies of those advanced civilized creatures.

Although they are all meat, they all have their own civilization like humans. Even if the shape is strange, Xu Yi thinks it is impossible to eat.

At the same time, he did not want other creatures of advanced civilization to eat humans.

If there is such a civilization, Xu Yi thinks it's better to concentrate on killing them.

It may not be acceptable to become the food of another civilization.

However, you have to have enough strength.

If the fierce beast has an idea, it is estimated that it will choose to kill all humans at the first time and let humans disappear completely.

Unfortunately, although there are fierce beasts on this planet that are completely more powerful than humans, they have not found that humans have begun to invade their planet.

For all the fierce beasts of spirit blue star, humans are invaders.

Xu Yi admits this, and so do other humans.

However, for their own survival, they can only attack the fierce beast.

If you don't start, you will be eaten by fierce beasts and will be extinct.

Therefore, humans would rather choose to exterminate other fierce animals to maintain their own survival.

Any creature, any civilization, the lowest requirement is survival.

In order to survive, in order to continue life, one species is completely indifferent to the ideas of other species.

This applies not only to mankind, but also to other civilizations.

"Xu Yi, I've recovered." after five hours, Lu Ke's mental strength has completely recovered.

If you are active in the territory of level 10 fierce beast, you must ensure that you have sufficient mental power.

Otherwise, it will be very troublesome if we encounter fierce animals acting in groups.

Xu Yi and Lu Ke have met three fierce beasts together. They fought. As a result, both of them were seriously injured.

If Xu Yi hadn't taken out the primary quick recovery medicine, they might need a day or two to recover from their injuries.

Therefore, the explosive inflammation of Xu Yi and Lu Ke can be used to deal with many fierce beasts.

The secret skill can actually be regarded as a group attack.

"OK, let's continue to look for level 10 fierce beasts and see the effect of ice." Xu Yi and Lu Ke said, and then began to move towards the front.

The red brain crystal has been put away by Xu Yi before. There is not much loss of brain crystal in it. It is estimated that there is still 90% mental power left.

Such brain crystals are even high-quality brain crystals.

Unfortunately, when it was dark, neither of them met a level 10 fierce beast.

Then they found a place to set up their tent.

Then Xu Yi took a turn around.

Now, Xu Yi began to restore the record of plants.

Because, with the scientific research department, he can take out so many drug treatments given by the system.

It's not enough to rely on him alone, so we need a large department specializing in plants. There is also a small department specializing in formula research and a department producing drugs.

Now, the pharmaceutical department is being established, and people interested in plants are gradually joining the team of the pharmaceutical department.

In the future, many potions will flow out of this pharmaceutical department to help countless gods and mages improve their strength.

The formulations of those potions are primary. Xu Yi now needs intermediate and advanced potions.

Although it hasn't been obtained yet, Xu Yi knows that the system must have some. It's just a matter of time.

What humans have to do now is to find out all the plants.

Once the properties and habits of plants are understood, they can find corresponding plants to develop drugs with the same effect to help human beings improve their strength.

Only by this means can all mankind become stronger and have the opportunity to surpass other civilizations and have the strength to protect mankind itself and protect a new home.

The tragedy on earth can never be repeated again.

Human beings can have a retreat, but they can't have a retreat every time.

The strength is enough and the level of science and technology is enough. Even if the sun explodes, human beings have the ability to protect themselves.

Even, an artificial sun can be built to maintain the needs of survival.

Therefore, this medicine has an incomparable effect on human beings.

There is no meaning in hiding this knowledge.

Xu Yi's energy is limited. It's impossible to devote a lot of energy to studying these things when practicing. What he can do is to analyze every plant he meets, and then record their data and send it to the people in the pharmaceutical department.

Xu Yi took a turn, saw two new plants and recorded them.

By the time he returned to the tent, Luke's dinner had been cooked.

After dinner, the two people also discussed their experience and conjecture about the use of secret skill explosive inflammation, and then went to practice together.

The next morning, Xu Yi and Lu Ke finished their cultivation early.

After breakfast, they set out and continued to look for level 10 fierce beasts.

Less than an hour after their departure, the two met a bird and a fierce beast.

So Xu Yi made a decisive move.

Xu Yi uses the secret script frozen. When he uses it, Lu Ke can feel the sudden drop in the temperature around him.

A mass of cold air rushed directly to the flying bird and beast, and it was frozen in an instant.

When the cold hit the fierce beast, it turned into huge ice. It was estimated that it weighed several tons. It hit the ground directly from the air and made a pit on the ground.

However, the ice did not break, not even a crack.

"The ice is quite strong. I only used 20% of my mental power, but I turned it into ice directly, and it froze to death." Xu Yi pushed it back after sensing it with his mental power.

Cold, too cold.

He felt that the temperature of the ice was estimated to be a hundred degrees below zero.

The birds and fierce animals inside have no breath of life.

Frozen to death, it shows the strength of this secret skill.

Then, Xu Yi began to bombard the ice with spiritual force to see whether the fierce beast inside was really dead or something else.

As a result, Xu Yi found it difficult for his mental strength to blow away the ice.

Finally, Xu Yi broke the ice after using the spirit eater.

The fierce beast, bird, and ice broke into several pieces.

So it's really dead.

Compared with explosive inflammation, its advantage is that it won't completely destroy the bodies of fierce animals.

However, Xu Yi thinks that in this case, the meat of fierce animals is also difficult to eat. The taste of these meat is expected to become very bad.

Therefore, this secret skill is also suitable for use under specific circumstances.

The two men finished it. It was a fierce beast. After they got the brain crystal, they didn't continue to explore.

Instead, he stopped to recover his strength and studied the last secret skill by the way. The ice arrows fired at once.

Xu Yi thinks that this may be a more practical secret skill, which should not cause the embarrassing situation that the first two secret skills are very practical at present.

In addition, Xu Yi also taught Lu Ke this secret skill.

Lu Ke was surprised when he heard that Xu Yi had another secret skill.

Because Xu Yi's output is a bit like a sow.

Take out three secret skills one after another, and there is no interval in time.

If Xu Yi didn't show signs of using the horoscope and didn't leave Luke's sight, Luke would doubt whether he was secretly contacting the little sister of the spirit family every day.

Such a speed is really incredible.

As for Xu Yi's ownership of the system, Lu Ke has no conjecture.

After all, there is no system for such a civilization as the spirit family. How can Xu Yi have it?

"Xu Yi, it's quite reliable to launch the ice arrows at once. I don't think we need to test our hand with fierce beasts. We can use it directly. This secret skill is still a little different from the previous two." Lu Ke said excitedly after listening to the cultivation steps of the secret skill.

"Well, I'm going to show you." Xu Yi said, and then inspired his secret skill - ice arrows.

At the moment of using the secret skill, a cold air appeared in front of Xu Yi, which was a bit like the feeling of using ice. However, the temperature drop is not as strong as when ice is used, and the temperature is not so low.

Then, these chills are rapidly condensing into ice arrows.

It is estimated that there are hundreds of ice arrows, which are thicker than the bows and arrows used by humans.

After condensing the ice arrow, it shot out in an instant.

It's really a feeling that ten thousand arrows are fired at once. It's estimated that the process from heavy cold to ice arrows is less than 5 seconds.

It can be said that the speed is very fast.

Then they saw the front row of trees blown to pieces.

When the ice arrow hits the target, it will explode and destroy the target.

"It's called ice arrow. How can I feel like our human rocket?" Lu Ke stared at the open space in front of him.

The power of ice arrows is very powerful for Lu Ke.

"It's really like that!" Xu Yi couldn't help grinning. This power and effect are really good.

As Lu Ke said, it feels like a rocket.

Moreover, the power of ice arrow explosion is much greater than that of rocket. In addition, the power of the explosion is also relatively concentrated and will not spread particularly powerful.

A hundred ice arrows exploded without forming a strong shock wave.

However, the concentrated targets were all destroyed.

"I'm really a genius to understand such a powerful secret skill." Xu Yi said shamelessly. After all, he couldn't say that something was given by the system.

Exposing the system won't do him any good.

Maybe it will bring him a fatal crisis.

Xu Yi is a genius, which Lu absolutely agrees with.

Otherwise, how did those martial arts, Kung Fu and current secret skills come from?

"I want to see what effect it is to use this secret technique of simultaneous firing of ice arrows to deal with fierce beasts. Xu Yi, how much mental power have you just used?" Lu Ke said with great expectation.

Because it is not dark yet, and even if it is dark, it will have no impact on them.

The spiritual vision, Xu Yi, has been handed over to Luke.

So now, day and night are not much different for them.

Or keep walking at sunrise and resting at sunset, just want to maintain some human instincts and habits.

"Less than 20 percent." Xu Yi's control over the secret skills is becoming more and more accurate, so he uses less and less mental power.

"Well, let's go find the fierce beast to try?" Lu Ke thought that the simultaneous firing of ice arrows might be the most practical of the three.
