After Zhou Zhi and his companions entered the temple, a faint light emanated from each of them. Even a layer of faint lime color appeared on Zhou Jie's skin. Xu Feng was a wizard in his previous life, and he could tell at a glance that Zhou Jie was casting a spell called Stoneskin.

The spell Stoneskin is actually somewhat similar to Petrify, but the strength of Petrify is much greater than Stoneskin. Stoneskin is equivalent to a weakened version of Petrify. The lime-like substance on the surface of the body has little effect on Zhou Jie's movement.

Xu Feng only recognized the magic cast by Zhou Jie. As for the skills of Deputy Director Zhou Zhi, Di Qiu, and Hou Zijian, Xu Feng could not see them.

At this moment, Zhou Zhi seemed to have thought of something. He turned around and looked at Xu Feng. He couldn't help but slap his head: "Damn it, I forgot about Xu Feng! Xu Feng, do you know any body protection spells? If not, leave the temple now. The netherworld aura here will hurt you!"

Every member of the elite team has mastered a unique defensive technique. Zhou Zhi didn’t take this seriously at first, but after entering the temple, he suddenly thought of this.

Xu Feng smiled and shook his head: "It's okay, the Netherworld aura here is harmless to me!"

Zhou Zhi was shocked, but nodded expressionlessly and continued to walk inside. In his heart, he was wondering how Xu Feng, a newcomer who had just stepped into the third-level apostle, could master the defensive technique so quickly.

You know, even the most common defensive technique is worth millions on the market, and ordinary defensive techniques can only weaken the erosion of the netherworld aura in the temple, but cannot completely resist it.

With Xu Feng's current financial resources, he probably won't be able to buy a book on spiritual-level defensive techniques.

In fact, both Xu Feng's black iron body and the devouring body can completely resist the erosion of the Netherworld aura, especially the devouring body. Since entering the temple, Xu Feng can feel that a large amount of Netherworld aura is being devoured by the devouring body. It is precisely because the devouring body devours a large amount of Netherworld aura that continues to emerge around Xu Feng's body, and even small whirlpools are formed around Xu Feng's body. This is entirely because the devouring body causes the density of the Netherworld aura around Xu Feng's body to be greatly reduced.

Fortunately, the temple was dark, and the gray-white mist produced by the Netherworld's aura was like chaos, making everyone's field of vision extremely narrow. If you didn't stare at Xu Feng carefully, it would be difficult to notice the abnormality of the devouring body.

At this moment, a green fireball the size of a human head suddenly flew out from the distance. Zhou Zhi, who was walking in the front, swung his heavy sword and chopped at the strange green fireball.

With a "bang", the fireball hit Zhou Zhi's heavy sword and exploded, with green flames splashing everywhere like a ghost fire.

"Be careful, there is a necromancer!" Zhou Zhi said in a low voice.

"Hehe, I'm lucky to meet a fellow warrior. I hope he can drop a spell book about undead things this time!" Zhou Jie laughed.

Xu Feng in his previous life, like Zhou Jie now, also pursued the number of spell skills, but did not care about the types of spells mastered, because low-level apostles cannot convert mental power into magic power, and only when they reach the fourth level will they be exposed to information on converting mental power into magic power.

If spells are cast solely by mental power, any type of spell can be cast. This is one of the reasons why apostles pursue the number of spells instead of the types.

However, if an apostle of the mage profession masters too many different types of spells, it will have a great impact on the later stage. First of all, when he breaks through to the fourth level and masters the basic laws of the magic system and meditation, the conversion of mental power into magic power will become extremely turbid.

For a mage, the purer the mana, the faster he will be promoted and the more powerful the spells he will cast. Turbid mana will seriously affect the combat effectiveness of a mage apostle. There will even be an embarrassing situation where a fourth-level mage apostle's combat effectiveness is even worse than that of a third-level mage apostle because of turbid mana.

How happy it is to master different types of spells in the early stage, how painful it will be to purify the mana in the later stage. In the previous life, Xu Feng spent at least three years to purify the mana to the point where it could be used after he was promoted to level 4. But at that time, it was impossible to have pure mana. The later it was, the more difficult it would be to purify it, and the time and energy spent would increase exponentially.

In the end, Xu Feng only purified his mana to 87% and gave up! "Brother Jie, I think it would be better for you to specialize in one type of magic!" Xu Feng frowned slightly, hesitated for a while, and said tactfully.

"Learn a series of spells?" Zhou Jie was stunned and shook his head. "Unless you can get a large number of spell books of a series, it is impossible for a low-level wizard to learn only one series!"

Xu Feng sighed and stopped trying to persuade him. What Zhou Jie said was true. For ordinary mage-class secret realm apostles, it was already very lucky to get a spell book. How could they force themselves to always get a series of spell books? "Unless you have a big power behind you, or can pass the exam to the six major mage departments, otherwise, it is too difficult to master only one series of spells at the low-level apostle stage!" Xu Feng thought to himself.

After a while, three skeleton undead walked out of the gray-white mist. One of them held a bone staff burning with ghost fire, and the other two held bone knives and bone shields and wore bone armor. It was obviously the configuration of a mage and two warriors.

"That necromancer belongs to me!" Zhou Jie said impatiently. Only necromancers have a chance to drop a skill book of necromancy. Although the chance is very small, Zhou Jie is unwilling to miss any opportunity! "Hehe, while the buff is still there, leave the skeleton warrior on the left to me." Hou Zijian said with a smile. As a thief, frontal assault is not his forte, but now the buff of "War Horn" has not disappeared, Hou Zijian feels that he can completely crush the opponent with his current strength.

There is no wrong version in the 1619 book forum!

"Come on together, be careful, don't be careless!" Zhou Zhi said, and rushed forward first, waving his heavy sword. The others were stunned, cursed them in their hearts for being despicable, and rushed towards the three undead monsters together.
