At that time, since the people of the Iron Warehouse could not prevent the Kui Erosion Demon from infiltrating the territory of the Iron Warehouse Clan, they had to find a way to learn the news of the invasion of the Kui Erosion Demon as soon as the Kui Erosion Demon had a move—whether it was the news of the individual Turtle Erosion Demon's infiltration, or the news of the Turtle Erosion Demon's organized war, it needed to be known as soon as possible.

So, just when some soldiers were guarding the border with fear, the Tiecang tribe bought some demon bells from a monk named Chi Yue, and once a demon approached the border of the Tiecang tribe, the demon bells would ring to remind the soldiers of the Tiecang tribe to take measures.

At first, the people of Tiecang were not sure whether the demon bells were useful, and they were even more worried that the unknown Chi Yue would be bad for the Tiecang clan, so they refused to buy these demon bells.

Later, when Chi Yue saw Tie Wandao alone, he said that these demon bells were left to this day more than 300 years ago, and told Tie Wandao about the events of more than 300 years ago.

Chi Yue said that her ancestors were people from the Fengli tribe more than 300 years ago, and her ancestors had been practicing since they accidentally got these demon bells after the war.

Because of these demon bells, her ancestors appeared with strange abilities, and after cultivation, the strange abilities were greatly increased, and then this strange ability was passed on to the descendants, and the descendants further cultivated on the original basis.

Since the ancestors got the demon bell, her family has been a monk for generations, and they all have a lot of research on demon prevention, but except when they come out to do things, most of them live in seclusion in the mountains and wilderness the rest of the time, even when they come out to do things, they are used to being incognito, this time because they have to sell these demon bells to win the trust of the Tiecang tribesmen, she told Tie Wandao her name and life experience.

At this point, Tie Wandao was still skeptical and asked her about the "Demon Swordsmanship".

Chi Yue told him that the "Demon Swordsmanship" was created by her ancestor Chi Qinglian, but because the descendants had other more effective methods of preventing demons, no one had seriously practiced this kind of swordsmanship, so none of the descendants practiced it.

Tie Wandao let her practice for a while at that time before she was sure that she really knew this kung fu. Tie Wandao asked her why she had to sell these demon bells, she said that it was a task handed down by her ancestors more than 300 years ago, and when there were demons attacking civilians again, they would sell these demon bells to the anti-demon invasion institutions, and the money obtained would be given to the civilians, so that they could accumulate merit to ensure that their descendants would continue to be good monks.

Tie Wandao wanted to keep her to resist the Gui Erosion Demon, only to know that she had lost all her strange abilities due to saving people not long ago, and she was about to sell the Demon Identification Bell and then retreat into seclusion in the mountains and fields to cultivate from scratch.

After Tie Wandao figured out the situation, he bought these demon bells. Although there is a demon bell, and the demon bell also plays a great role in letting the people of Tiecang know the news of the invasion of the Gui Eclipse Demon for the first time, the soldiers guarding the border of the Tiecang tribe are limited in ability after all, and the civilians of the Tiecang tribe outside the Tiecang court will still be occasionally disturbed by individual Gui Eclipse Demons.

It wasn't until the first defeat on the battlefield to the Tiecang Army led by Tie Hongyan that they didn't attack civilians again, because those Gui Erosion Demons had all gone to retreat and cultivate to prepare for the next war.

After that, due to the fact that the Gui Eclipse Demon was beaten by the Iron Red Flame and the troops, all the Gui Eclipse Demons never attacked civilians again under the control of the Demon King, because the commander of the Gui Eclipse Demon Demon King found that the Gui Eclipse Demon who had attacked the civilians in private action was greatly damaged, and such a Gui Eclipse Demon had no combat effectiveness on the battlefield.
