Once the Void Silkworm makes a mistake, and the Ethereal Silk is not destroyed by the Void Butterfly, it will drift into the Endless Void.

Because ethereal silk is a precious material used to make Lingwu armor, adding a little ethereal silk to the Lingwu armor can increase the defensive ability of the armor by at least 20% or more, so whenever a hundred years reach the time when the virtual silkworm molts, there will be some big forces, using special methods, sneaking into the vicinity of the gathering place of the virtual silkworm, just waiting for the war, and start collecting the ethereal silk.

However, whether it is an ethereal butterfly or a void silkworm, they are all social void beasts, and they are also high-level void beasts, even if the Divine Monarch encounters so many high-level void beasts in the void, he can only run away.

Therefore, when the major forces send people to collect the ethereal silk, they will be far away from the place of battle, just waiting for the ethereal silk to fly over by itself.

However, because the ethereal silk is very important to the Void Silkworm, after the war, the Void Silkworm will recycle the ethereal silk, so the time to collect it is only the time for the Void Silkworm to molt and fight, and as soon as the time is over, it must be retreated.

Therefore, every hundred years, the major forces together can collect at most a ten-meter-long ethereal silk.

If Zhang Chenfeng wanted ethereal silk, it would be impossible to collect it by himself, and if he couldn't collect it, he could only get it from these big forces.

But the problem is that ethereal silk is the most precious kind of material for making spiritual armor, every hundred years, the major forces of the Human Alliance combined can only collect a dozen meters long, and Zhang Chenfeng needs one meter of ethereal silk to transform the spirit bag.

Don't look at it as only one meter, but it's very long!

One meter of ethereal silk, plus some other special precious materials, is enough to refine a Lingwu-level armor.

Zhang Chenfeng wants a meter-long ethereal silk, and the major forces may not have it, but even if there is, how difficult it is to get it can be imagined.

Zhang Chenfeng thought about it, and if he wanted to get the difficulty of the ethereal silk, he had a headache.

Ethereal silk is too precious, and the value of one meter of ethereal silk is much higher than that of some middle-grade heaven and earth holy medicines whose effects are not so special.

Not to mention whether those big forces will sell the ethereal silk, even if they are willing to give it, they can't afford to change it now.

"Hey, forget it, let's find a way when we go to the Human Alliance in the future, and then collect other materials by ourselves!"

After Zhang Chenfeng sighed, he walked out of the grotto, came to the passage, and walked out.

Every time Zhang Chenfeng passes through a cave, he will

Take out a piece of Ice and Fire Rebellion Stone from the spatial ring and throw it into it, and throw it in the small pool of water in the cave.

In each cave, there is a small pool, which is specially dug by Zhang Chenfeng, after all, in a cave, each cave is thousands of strange beasts, and it is troublesome to feed water every day.

In the Alien Beast Cave, there are sixty-three caves where alien beasts are placed, which means that Zhang Chenfeng has a total of sixty-three Ice and Fire Rebellion Stones.

This is also Zhang Chenfeng's knowledge that the headquarters of Wuyinglou produces ice and fire rebellion stones, and the number is sure to be very large.

Otherwise, where would Zhang Chenfeng use the Ice and Fire Rebellion Stone so extravagantly?

Like the two Ice and Fire Rebellion Stones that Zhang Chenfeng got when he was on Earth, Zhang Chenfeng was willing to use them when he was cultivating the top ten Gu beasts on the Gu Beast List.

After Zhang Chenfeng put the ice and fire rebellion stone, he walked out of the alien beast cave, and then came to Mrs. Zhang's residence, and after chatting with his mother for almost half a day, he calculated the time, and found that it was almost the time agreed with Jian Wushuang, Zhang Chenfeng said goodbye, walked out, and came to the stone tablet forest, the only stone tablet without words, and waited on the side.

This wordless stele is the opening of the passage in the Xuantian Secret Realm, and if you open the passage outside the secret realm, the passage will appear on the side of this stele.

Zhang Chenfeng came to the front and back of the stone monument, and did not wait long before the passage appeared.

Zhang Chenfeng watched the passage appear, and stepped directly into the passage.

In front of the stone tablet of the Heavenly Sword Gate, after Jian Wushuang activated the passage, he had been waiting for Zhang Chenfeng here, and after seeing Zhang Chenfeng come out, he breathed a sigh of relief.

Jian Wushuang was really afraid that Zhang Chenfeng would be delayed in the secret realm and delay time.

Before Zhang Chenfeng went in last time, he asked the health doctor to pass through the Shadowless Building and made a nine-day covenant with Fengyun Lingjun, if Zhang Chenfeng was wrong this time, when Fengyun Lingjun came over, then Jian Wushuang didn't know how to explain.

Although the matter of the secret realm of the Heavenly Sword Gate is not unknown to outsiders, but the outsiders who know it are all those who will not have the slightest interest in the secret realm of the Heavenly Sword Gate.

Even if Zhang Chenfeng has the identity of an elder of the Mainland Famous Doctors Association, Tianjianmen doesn't want to live in peace!

After Zhang Chenfeng came out of the secret realm, he saw Jian Wushuang and smiled slightly: "Senior brother, thank you for your hard work!"

Jian Wushuang shook his head with a smile and said, "A little thing, what's so hard!"

Sword Warrior

After laughing, he said to Zhang Chenfeng: "Senior Brother Zhang, in a few days, we will be the disciples of our Heavenly Sword Sect, how about it, are you interested? If you are interested, I will leave this matter to you!"

Zhang Chenfeng shook his head with a smile and said: "Don't get involved with me in this matter, senior brother, you also know, I had an appointment with Fengyun Lingjun before I went in, and when Fengyun Lingjun came over in two days, I would go out with him for a while." ”

"That's it, forget it!" Jian Wushuang originally thought about asking Zhang Chenfeng to come forward and show the majesty of the Heavenly Sword Gate, but after hearing that Zhang Chenfeng was going out, he immediately dispelled this idea.

Jian Wushuang didn't ask Zhang Chenfeng where he was going.

Jian Wushuang knew that if Zhang Chenfeng could say it, or could tell himself, he would definitely tell himself, if he didn't say it now, it would mean that the place he was going to was special, and he couldn't know it.

Jian Wushuang is not worried about Zhang Chenfeng's safety after he goes out, since he is with Fengyun Lingjun, then Fengyun Lingjun will definitely protect the safety of his junior brother.

His junior brother is an elder of the Mainland Famous Doctors Association, if something happens to him when he goes out with Fengyun Lingjun, even if Fengyun Lingjun is a Lingjun of the Spirit Rotation Period, he can't bear the wrath of the Mainland Famous Doctors Association.

"That's right, senior brother!" After Zhang Chenfeng rejected Jian Wushuang, he suddenly remembered one thing and said to Jian Wushuang: "When I go back, I will give you a book on the way of demonic energy, as well as an exam paper and answers, and when the mountain gate is opened, you will send that book to those new disciples." ”

"Give them seven days to read the book, and then, send the exam paper down, according to my answers, if anyone can answer the eight questions correctly, they will be directly accepted as inner disciples!

Jian Wushuang's eyes lit up when he heard this, and he said, "Senior brother, do you want to really accept apprentices?"

"Really accept apprentices?" Zhang Chenfeng shook his head and said: "No, at most, it's just a few family disciples, if anyone can answer the nine questions correctly, I may think about it!"
