After clearing the soul poison of these people, the three of them disappeared into the void, not wanting to meet these people, watching these people wake up, and leaving one by one inexplicably, as for where they went, Xue Dong and Lile didn't bother to care about them.

Xue Dong refined a mask for Lan Jia, so that as long as he didn't do it, no one would be able to know that he was a demon, and there were people from the demon clan in the fairy camp to join, although it would still be known in the future, but at present, try not to make it known to everyone.

Back at the Eastern Emperor's Mansion, Xue Dong unexpectedly found that there were several people waiting for him here.

Qiu Wei, Bai Lin, Chaoyang and Kong Bichun were also there, and Liu Han was also standing aside.

It turned out that as soon as he entered the demon realm, the clone who stayed in the Star Sect could not sense his existence, Chaoyang was too frightened, so he immediately rushed to the East Emperor's Mansion, and he had to wait here until Xue Dong came back to feel at ease, as soon as he came, Kong Bichun, who had been on the front line for a few days, also came.

Qiu Wei and Bai Lin were also worried about his safety, and they were waiting for him here when they had nothing to do on the front line. But in a few days, everyone felt that it was like a year.

Xue Dong is not only their good apprentice and junior brother, but also the hope of the battle of immortals and demons.

Seeing the appearance of Xue Dong and Lile, no one paid attention to Lan Jia, the masked man who was clearly standing together, and they all surrounded him.

"Xue Dong, you're back. "A sentence contains a thousand emotions, more than a thousand words.

"Yes, we're back!" Xue Dong was also very moved when he saw everyone's concern for him.

On Huaxing, the eighty-eighth clone didn't tell Xue Jingui and Wu Xue about his going to the Demon Realm, so as to save them from worrying.

At this time, everyone put their hearts down, Liu Han looked at Lan Jia who was wearing a mask and asked, "Who is this Taoist friend?" Xue Dong, you can also introduce us to us!"

"Oh, this is the Daoist friend we met in the Demon Realm. ”

Then Xue Dong told him about the experience in the Demon Realm again, but the things that happened next to the teleportation array were all mentioned by him, and there was no need to worry everyone because of the past.

"I didn't expect the Terra Stones to be so effective against the demons, how do I plan to use these Terra Stones?"

When Xue Dong came back, Liu Han forgot that he was the commander-in-chief of this war, and asked Xue Dong directly.

"Some of these Terra Stones I want to refine into weapons, more I want to distribute them to our army of monks, so that they can directly shatter these Terra Stones and use them as weapons to fight directly at the demons, and some of them I will make into various new weapons.

It's still very simple for the Terra Stone to be processed by our Immortal Realm monks, and this matter will be done by our Star Sect, in short, the number of Terra Stones brought back this time is enough for the Demon Clan to drink. In just a few days, we will be able to launch a general attack on the demons. ”

"Okay, then I'll let the Three Domains start to surround the border of the Northern Regions now, and see how long these demons can be arrogant. ”

Xue Dong found an open place and dumped most of the Terra Stones, and a large number of Terra Stones piled up here into a mountain.

Although the army of immortal monks went to participate in the siege, at least they were all monks of the Golden Immortal Realm, and these Terra stones could only be divided into a few pieces per person, but there were hundreds of pieces when they were shattered.

And what is beaten can also be reclaimed and reused, only need to put its own mark on each fragment, just like refining weapons, and it is easier to refine than weapons.

Xue Dong took away a small part of the Terra Stone, some of which he planned to refine into regular weapons for use in fighting against the high-level of the Demon Clan, and some of which he would refine to deal with masters of the Demon Lord's level. It's just that such a ** still needs to be tested before it can go to the battlefield.

Xue Dong, Fence Le, Lan Jia, and Bai Lin came to the Star Sect Refining Hall's station in the wilderness together, Xue Dong handed over a part of the Terra Stone to Bai Lin, and asked him to refine conventional weapons to be used by the high-level of the Immortal Domain, and he went to study the new ** with Fence Le.

The Four Great Emperors of the Immortal Domain and the Four Demon Lords of the Wilderness were called to the Eastern Emperor's Mansion, Liu Han asked them to take away those Terra Stones and told them how to use them, although several emperors could not believe that this was an ordinary ore and that it had a special effect on the demons, but Liu Han had indeed given them a lot of surprises since the war, so they all strictly carried out Liu Han's orders.

They brought these Terra ores back and distributed them to each monk, telling them to shake the ores into pieces, and put their own soul marks on each fragment, and use this to fight against the demons, and after hitting the demons, they can also take them back and reuse.

Regardless of whether this statement is credible or not, does this little particle really have such a good effect on the demons?

When these preparations were completed, the Four Great Emperors began to organize the monks above the Golden Immortal Realm to teleport to the border of the Northern Regions.

Xue Dong and Fence Le encountered difficulties in bomb research, Xue Dong used fairy stones as fuel, Terra stones as shrapnel, and Fence Le as the test object, but no matter what kind of **, Fence Le could dodge, and those Terra Stone fragments could not hit her, which also meant that they could not hit the Demon Lord.

Once the three domains surround the northern region, the battle of immortals and demons will start immediately, and both sides will not be able to face each other without moving, after equipping the immortal domain with the "hidden weapon" of Terra stone, Xue Dong is not worried about the battle of ordinary monks, but he will fight with the demon lord in the future, and even Fence Le is not his opponent, and he will not be able to cultivate to the late realm of the immortal emperor in a short time.

He understands all the knowledge on the earth, and with the immortal materials, the ** he made is much stronger than the bombs on the earth, but the fence music can always be avoided, not to mention the demon lord who can turn into black smoke.

However, Lan Jia put forward a little opinion, "Although the girl can dodge Xue Gongzi's **, she is not under pressure from a third party, if she is under pressure from a third party, I am afraid she will not be able to dodge like this**, if the demon lord appears, she will naturally have the highest combat power of the fairy realm, and she will naturally not be able to dodge as she wishes." ”

There is some truth to this, but it is not enough insurance, and it is better to have a way to make people unavoidable. "Luckily, Terra Stone didn't do any harm to the fence, and his experiments could go on endlessly.

Xue Dong tried to melt the Terra Stone into a liquid state, keep it unchanged with the power of time, and then burst out with the Immortal Stone, so that the Fence Le really couldn't dodge, but even if the Terra Stone Liquid was poured on the Demon Lord's body and didn't penetrate the flesh, the harm to him was extremely limited, let alone killing him.

In his continuous experiments, Xue Dong thought of another question, what effect did the demon's attack have on the Terra Stone?

Then he called Lan Jia and asked, "Lan Jia Daoyou, I want to refine a pair of battle armor, using Terra Stone as raw material, I don't know what the effect is, can you give some advice?"

"Xue Gongzi's idea is really good, no one has ever tried it in my demon clan, because the Terra Stone is harmful to my Demon Clan, and the weapons refined by the Terra Stone are usually placed in a separate place in the storage space, and they cannot come into contact with other magic weapons, otherwise they will corrode the spirituality of the magic weapons.

As for the Terra Stone weapon, it can only be resisted with the same Terra Stone weapon, and other magic weapons, no matter what grade of magic weapon, cannot withstand the attack of the Terra weapon.

When I fought with my master in the mine, I could only resist with the shield of Terra Stone, and other magic weapons could not resist it, and it was possible that it would be damaged by Terra Stone. Langa said.

When Xue Dongxiang was in the teleportation array, when the demon lord used to shoot away the Terra Stone that attacked him, he also used a Terra Stone Refining weapon.

Since bombs can't be used, let's refine battle armor.

After only a while, Xue Dong refined a pair of battle armor, Xue Dong put on the battle armor, and let Lan Jia attack him in the air, only to find that with the Terra Stone Battle Armor, Lan Jia's magic attack on himself was weakened by at least eighty percent.

No matter how much Lan Jia used the magic weapon to carry out a physical attack, he couldn't penetrate the battle armor, and Xue Dong couldn't feel too much attack strength, and after several attacks in a row, even the magic weapon was so damaged that he couldn't use it anymore.
