After the level of the magician reaches the fourth level, it is very difficult to improve every time, and the senior magician can already perform group attack magic, and it is also from this time that the magician begins to have a destructive power far beyond that of the fighter, and after reaching the great magician, he can perform group gain magic, and his strength soars again, at least, feeling the magic and spiritual power in his body now, Gu Feicang feels that if he deals with his previous self, it will be effortless at all.

As the power of nature poured into his body little by little, Gu Feicang's realm gradually stabilized, and on the contrary, it was the power of the ancient tree of wisdom, only to see that the power of nature in Mu Xin was scarce little by little, and without the resistance of the power of nature, the black death power suddenly eroded the green that was originally only the last bit.

"Alright, dear Francisco, my strength has been exhausted, and this place is about to be completely eroded by the dark forces, so you get out of here at once and follow the last rays of the green light, or it will be too late. “

Yuris's voice became more and more old, and then, he saw a green light hitting into the distance, which immediately attracted the attention of the undead in the land of eternal night, seeing this, Gu Feicang looked at the huge ancient tree in front of him, gritted his teeth, and turned to leave.

After becoming a great magician, another very significant feature is that he can fly in the air with the help of the power of magic elements, if he specializes in learning the magic of the wind system, he can fly more freely, and now, although Gu Feicang has the strength of a great magician, he has not really learned the fifth-level magic, so he can only use the power of magic elements to float in the direction of the green light.

I saw Gu Feicang float all the way out hundreds of meters away, and finally, after exhausting the last trace of natural power, the ancient tree of wisdom that could not stop the erosion of the dark power began to collapse and decay under the erosion of the dark power, and the huge tree that was originally pitch black was dyed with a layer of death aura gray, and the huge body had no support of strength, and began to collapse and decompose, and the huge branches and leaves broke away from the trunk and fell to the ground, stirring up billowing dust and smoke, like a volcanic eruption, covering this piece of sky.

Looking at the rising dust and smoke, Gu Feicang stood in place for a long time, and finally sighed, even if it was as powerful as a wisdom ancient tree, it would eventually turn into dust and smoke, and for a while, there was a feeling of dullness in his heart.

However, this emotion did not linger in his heart for long, after all, this is the land of eternal night, full of endless undead, and the light released by the ancient tree of wisdom just now in order to show him the way is not a breath of life, but it is also very obvious to the undead who hate the power of nature.

What's more, without the existence of the Ancient Tree of Wisdom, the dark storm in the valley has also lost its source, as the undead who are the most sensitive to the dark power, I am afraid that the existence of this will be felt at the first time, if I don't leave early, I am afraid that I will soon fall into the siege of the undead.

Thinking of this, Gu Feicang hurriedly summoned a griffin, after becoming a great magician, the biggest advantage is that he can cast group magic, and the masking magic can also cover the life breath on the griffin's body when covering his own breath, without worrying about being detected by the undead.

After having a griffin, Gu Feicang's speed was several times faster, after all, the speed of the griffin's flight was originally higher than that of the horses, and the number of undead in the sky was also significantly less than that on the ground, flying at high altitude was basically smooth.

In this way, after a few days, Gu Feicang did not encounter any undead, and he had been lacking resources due to the continuous use of magic scrolls, and finally built the last building in the third-level building, the magic pool, under the stable life of these few days.

The magic pool has the power to produce resources immediately, for Gu Feicang, although the role of this building is there, but under the condition that there are councils, docks and other buildings that can produce resources, the role is not particularly obvious, however, the appearance of the magic pool is not completely useless, that is, after the construction of the magic pool, several troop buildings in Gu Feicang's hands can be upgraded.

The first one that can be upgraded is the Gryphon Tower, which can be upgraded to the Royal Griffin Tower after consuming 3,000 gold coins, 30 stone points and ten Force Gems, and at the same time, while upgrading the Griffin Tower, the barracks can also be upgraded to the Crusader, which is cheaper than the Royal Griffin Tower, only 4,000 gold coins and 10 wood points.

First of all, the griffin has become a royal griffin, the royal griffon, with a stronger body than the griffin, the body size is much larger than the original griffin, and the feathers on the head have also become hard armor-like feathers, a pair of wings are larger, and the speed is much faster than the original griffin.

In addition, compared with the griffin, the royal griffin has the biggest feature that it has been trained by the royal mage group all year round, and the royal griffin has an unparalleled ability to resist demons, and also has the power to perform magic, although this magic power is too different from his original strength, but with this increase, the royal griffin, which is only a third-level griffin, can not fall behind when fighting against some fourth-level professionals.

In addition to the Royal Griffin, the strength of the swordsman has also increased significantly, after upgrading the barracks, the Crusaders can recruit the Crusaders, as the guardians of the Templar Castle, the Crusaders have a strong physique, strong fighting spirit, and also have an unyielding will, in battle, the Crusaders because of their belief in the Holy Light, ignore any debuff magic, and in the face of a crisis, can exert 200% combat effectiveness.

Moreover, with the power of holy light, they have significantly enhanced both in combat effectiveness and defense, coupled with the training methods that Gu Feicang has, they can also form a camp, share damage, and fuse attacks, the combat effectiveness of a team of crusaders is probably not much weaker than a team of fifth-level powerhouses.

Of course, if it is a single strength, without the bonus of the team, there is still a gap compared with the fifth-level powerhouse.

This time, the only thing that made Gu Feicang a little disappointed was that the temple, which was also a third-level building, could not be upgraded, according to the setting of the castle space, the upgraded building of the temple belonged to the fourth-level building, and it was necessary to build a fourth-level magic guild before it could be upgraded, and before the strength reached the sixth level, Gu Feicang didn't have to think about it.
