Looking at the scroll in his hand, Gu Feicang's eyes were full of pain, the value of a scroll was simply comparable to a first-class building, and it was a lot of resources to use it once, if it wasn't for the fact that there was no way to get out, Gu Feicang would be reluctant to take out these scrolls.

Looking at the Lich King in the sky, Gu Feicang's eyes were full of murderous intent, "Fuck your mother, the old immortal Lich King, give Lao Tzu death!"

Gu Feicang shouted, and instantly threw the scroll in his hand, these four scrolls, all of them are scrolls of purifying light, and they are also the light magic that Gu Feicang has learned now, the most lethal light, I saw the four scrolls thrown out, and when they touched, the dazzling light exploded, and the power of the four purifying lights together was definitely not as simple as one plus one equals two, and in an instant, in the land of eternal night, it was as if a small sun had risen.

The light centered on Gu Feicang and quickly shot out in all directions, the holy light power was scattered, countless undead turned into ashes in the wail, the Lich King's gray eyes were full of fear, the wand in his hand waved, and the blood-colored light turned into a white bone shield, wanting to defend.

However, the lethality of the light power to the undead is too great, and the power of the four purifying lights burst out, I am afraid that it is no less than the power of a fifth-level light magic, and under such a rich light magic, the bone shield quickly dissolves and melts, emitting a foul smell.

Not only that, after releasing the four scroll scrolls, Gu Feicang also used the last bit of energy, raised his wand, and cast a purifying light.

Under the outbreak of four purifying lights, this purifying light was like the last straw that crushed the camel, and within hundreds of meters of the house, it was shrouded in rich light magic elements, and countless undead turned into flying ashes, and it was impossible to survive in such a situation at all.

In a wail, finally, the white bone throne in the sky cracked open, the dry corpse-like body of the Lich King began to shatter, the gray-black skin was the first to crumble, and began to burn under the light of holy light, and the wand made of white bone also began to shatter under the power of light, and the blood-colored magic crystal melted, like flowing blood, being evaporated little by little.

After a long while, this rich light power dissipated, and I saw that within a few hundred meters, bursts of green smoke came out, like a forest that had been burned by fire, and the scene was in a mess, and no half of the undead creatures could survive here.

Seeing this, Gu Feicang took a few breaths, hurriedly put away the troops, summoned a white horse, loaded it with magic props to cover his breath, and quickly ran away into the distance.

However, I don't know why, even if there are magic props that cover the breath, but along the way, Gu Feicang is no longer as easy as before, although he has never encountered a terrifying opponent like the Lich King, but the skeletons and zombies along the way, but faintly ignore the magic props that cover the breath, and often rush over, although there are not many of them, but it also makes Gu Feicang tired.

Because he was afraid of attracting a large number of undead creatures, Gu Feicang did not dare to summon troops, so he could only rely on himself, but during this period of time, not to mention anything else, his light magic became more and more proficient, and even gradually found out the tricks to save magic power, although it did not have much effect, but it still made him happy, which was a good start.

In addition, before, although because of the Book of the Sage, he exposed his existence in the land of eternal night and almost died in the siege of the undead, however, this matter was not completely without benefits, with the news that he wiped out the orcs' grain transportation team and destroyed the magic crystal worth tens of millions of Yafa gold coins, Gu Feicang became even more famous, and his prestige in St. York's town was also a little higher, and there were two more Force crystals in the castle space.

At this time, Gu Feicang was basically sure that the Force Gem and the Force Crystallization were related to the worship of the people in the territory, or the degree of loyalty and support, the higher the worship, the faster the speed of producing the Force Gem, as for wanting to produce the Force Crystal, in addition to worship, I am afraid that a high level of spiritual fluctuations is also needed, just like the last time the Force Crystallization was generated, it was when he repelled the orcs, and everyone's emotions were high, this time, it was also because of such news, and everyone's emotions were high.

Of course, this is just a guess by Gu Feicang, and it will take some time to verify the specifics, however, these two Force crystals have given Gu Feicang a lot of help, as Gu Feicang's strength is getting stronger and stronger, it is becoming more and more important to recruit powerful troops, but if you want to recruit monks, in addition to gold coins, you also need Force crystals.

Three monks can be produced in the castle space every week, but because the Force crystallization is not enough, for so long, Gu Feicang has only recruited one, and now he can finally increase a few, which makes Gu Feicang unhappy.

Therefore, as soon as he got these two Force Crystals, Gu Feicang recruited two monks, and looking at the three monks in the castle space, Gu Feicang suddenly felt that his strength had increased a few points.

After recruiting the monks, Gu Feicang built a new building, the Wisdom Wall, to build the Wisdom Wall, it costs six thousand gold coins, ten points of ore and ten points of Force Gems, the cost is not high, if it wasn't for some time ago, because of the production of a lot of magic scrolls, Gu Feicang would have been able to build this building a long time ago.

The wisdom wall is an upgraded building of the library, the library can randomly produce a book every day, and the magic president also said that the cultivation of magicians is to a large extent the cultivation of wisdom, and the more extensive the knowledge, the easier it is to sense the existence of the law in the future, therefore, every time Gu Feicang enters the castle space, he will also spend some time in the library to see the books produced inside.

If a magic spell is a type of problem, the wisdom wall is equivalent to a universal question type solution library, which can analyze and analyze a magic spell to the greatest extent, so that people can avoid many detours in the process of learning, and most importantly, the wisdom wall can allow you to continuously experience the feeling of successfully releasing magic, which is difficult to achieve no matter how you explain it.

After becoming a high-level magician, Gu Feicang obviously felt that the speed of learning magic was getting slower and slower, and the appearance of the wisdom wall was not a great help to him.
