Yun Feng is the head teacher of the low-level 001 class, and the students of the low-level 001 class are managed by him, which Yun Feng did not expect before.

However, since he was in charge, Yun Feng didn't mind restraining these little guys.

In the past in the Wolf Slaying Legion, he commanded many huge fleets, and it was no problem to manage this small class.

"Really practice very quickly......

"What Teacher Yun Feng said is true......

"My internal strength broke through to level ten in three days, and then my mental power also broke through to level ten......"

"My physical strength is higher than anyone else at the same level in our family......

"There is no unstable state at all......"

"I'll practice like this from now on......"

In just a few days, the students of the lower 001 class were all excited.

With the support of family resources, they practiced quickly.

Yun Feng goes to the Dragon Tiger Fighting Arena every day to watch life and death fights, and occasionally makes a bet without affecting the income of the fighting arena...... His main purpose was to absorb the spirituality of those dead fighters.

Under his special instructions, every time a fighter who was gifted as a fourth-level spiritual fighter fought to the death, the owner of the Dragon and Tiger Arena would personally notify him so that he would not miss it.

A few days passed, and his spirituality had steadily improved, the third fourth-level spirituality had grown, and the fourth-level fourth-level spirituality had also shown signs of splitting.

At this time, Yun Feng's spiritual power had already broken through to level 41.

His spiritual power was originally level 47, but because the level of spiritual power decreased, the level of spiritual power decreased......

Now that his spiritual level has recovered to the fourth level, his previous spiritual realm comprehension is still there!

Therefore, after stabilizing the realm of spiritual power level 40, he quickly increased his spiritual power to level 41.

At this rate, Yun Feng believed that it would not take him two months to recover his original strength......

However, this is only about his physical strength...... If you count foreign objects, he is far behind.

The crystal coins in his card now have reached 20 billion blue crystal coins.

Yun Feng was thinking about one thing, should he buy a mecha first and refine it into a spirit armor......

He has already decided to start provoking Li Jiannan, and if he doesn't prepare anything, it is easy to have problems with security.

It's just that his current spiritual power is still in the period of rapid rise, and the level 41 spiritual power can only refine a level 41 mecha at most, and refining a mecha is not so easy, it takes a lot of preparation and time......

After thinking about it, Yun Feng decided to buy a more advanced mecha.

Just by operating, his level 41 spiritual power can control a level 51 mecha!

If he could buy a level 51 mecha, the power he would exert would be stronger than if he could refine a level 41 spirit armor!

Although theoretically, the power of a level 41 spirit armor is comparable to that of a level 51 ordinary mecha, but in the end it is just a theory, and there are always some advantages in the mecha of the real advanced civilization technology.

If there is a level 51 mecha, he will also have a certain self-protection ability when he encounters something!

It's just that the price of a level 51 mecha is not cheap......

The level 51 mecha is already a product of the fifth-level civilization technology level, and in a fourth-level civilization like their Blue Source Empire, the price of such a high-level civilization product is even more than their original value!

A level 3 civilization technology level mecha, the price starts at a million red crystal coins!

A level 4 civilization technology level mecha, the price starts at millions of blue crystal coins!

A fifth-level civilization technology mecha, the price starts at one million Qingjing coins!

The color of the energy block of the level 5 civilization is cyan! The same low-grade azurite coin contains ten times more energy than a top-grade azurite coin! It's 10,000 times that of a low-grade Azurite!

One million blue crystal coins, equivalent to ten billion blue crystal coins!

And that's just the starting price!

The price of high-level civilization technology products is at least doubled in low-level civilization!

Mechs are strategic weapons...... The price is higher!

If Yun Feng wants to buy a fifth-level civilization technology level mecha, he doesn't have tens of billions of blue crystal coins, so he doesn't have to think about this matter at all!

Moreover, there must be special channels! This kind of high-level civilization mecha can't be bought without special channels!

The last thing is ...... Even if you buy it, tens of billions of blue crystal coins, you can only buy a mecha with the lowest level of fifth-level civilization technology!

Drawing this data, Yun Feng smiled bitterly in his heart.

His 20 billion blue crystal coins seem to be a lot, but compared to this consumption, it is very small. …,

However, this consumption is definitely worth it! If he had a mecha with a fifth-level civilization and technology, then in the future, as long as he didn't encounter a fourth-level civilization and technology level spirit ship, or a large number of fourth-level civilization-level fleets to encircle and suppress him, he would be sure to retreat with his whole body!

Although it is only a mecha, it is a thing of advanced civilization technology, and its power cannot be underestimated!

Even if refining a level 41 mecha and upgrading it to a spirit armor can also be compared to a level 51 mecha with a fifth-level civilization technology level in terms of some power, the cost of crystal coins will be many times less...... But the energy and time consumed was not what Yun Feng wanted.

He may encounter something at any time now, in case the level 41 mecha is not successfully refined by him, something big may happen......

Moreover, Yun Feng thought further!

His mental power is now improving very quickly! Although there was a reason why his original spiritual realm comprehension was still there, he felt that even if he returned to his original spiritual power level, his speed after that would not necessarily be much slower!

Every time he grew spiritually, he would feel his spiritual power boiling...... At that time, his mental power would soar rapidly......

This time...... He felt that his perception of the spiritual realm was deeper than before his original strength was not damaged!

He believed that when his spiritual power returned to his original realm, this feeling would lead his spiritual power level to a higher level!

Moreover, this time will not be too short!

Maybe...... Reach level 51 and this speed will be fast!

According to the current rate of his spiritual growth, it would not take long to be promoted to the fifth level.

As long as his spirituality breaks through to the fifth level! Then he is sure that in an extremely fast time, he will break through his spiritual power to level 51!

When the time comes, he will refine the level 51 mecha that he can buy into a spirit armor!

Level 51 spirit armor, comparable to the power of a level 61 mecha with a sixth-level civilization and technology level!

Once he succeeds, even if he faces the four 47-level spirit ships of that Tianhe, he will dare to have a heart of antagonism!

The level 41 mecha, if he refines it, he will only waste time and crystal coins in vain, and then there is no potential at all, and it will be eliminated soon.

Since you have decided to buy it, buy the premium one!

Thinking that he would be able to upgrade his spiritual performance to level five in the future and be able to possess a spirit armor with a level five civilization technology level, Yun Feng couldn't help but feel a burst of pride in his heart.

This time...... Will be ...... soon

Pity...... When he killed those people of the Poison Dragon Gang in the Dragon Tiger Fighting Arena, he didn't put away their spatial rings......

That Ouyang Qian is the deputy leader of the Poison Dragon Gang, and the subordinates he leads must be the elite of the Poison Dragon Gang, and there must be a lot of good things in the space ring.

Look at that Ouyang Qian, his level 53 energy cannon is a valuable thing.

It's time to find a way to make money! His current 20 billion blue crystal coins are far from enough to buy a level 51 mecha!

In the future, if you want to refine a level 51 spirit armor, you will need an astronomical amount of crystal coins!

His original plan can be carried out.

Jinlan Academy, as a special existence of Jinlanxing, has many resources.

Many of the students here have extraordinary backgrounds behind them.

These are resources!

"Teacher Yun Feng, Teacher Yun Feng, no, Barella was bullied...... There are students from other classes who want to bully us! As soon as Yun Feng returned to Jinlan Academy from the Dragon and Tiger Arena and parked the car, a little fat boy ran over and shouted at Yun Feng angrily.

"Tang Yuan, is someone bullying you?" Yun Feng frowned and asked.

In a few days, Yun Feng had already known the names of every student in the class, the name of this little fat boy was Tang Yuan, and the Barrele in his mouth was the little boy who had been provoking him with words when he was in class for the first time, and it was said that his uncle had a relationship with the director of the academy.

"Yes! Oh, yes! Teacher Yunfeng, hurry up and take a look, we can't beat them! Tang Yuan looked anxious, nodded again and again, and said.

"Let's take a look!" Yun Feng nodded and said.

Yun Feng followed Tang Yuan and walked in one direction.
