Speaking of charging before the battle, Ye Yun suddenly thought of an anime of an island country, the name of which he couldn't remember clearly, but he remembered that the robot or Gundam in it used electricity, and it was very, very strange that the electrical device of this Gundam was actually a pair of oversized batteries, you read that right, it was the battery, the kind of battery that was put in the remote control.

Ye Yun still remembers that in the anime, this gundam seems to be able to fight for only three minutes because of electrical energy, and once it exceeds this time, the electric energy will be exhausted, and then in order to prolong the combat time, the researchers clearly identified a battery missile, which can launch the battery during the fierce battle and replace the battery in the battle. Ye Yun now has a feeling that he fully charged the battery before the battle.

Ye Yun's No. 9 and the matchmaker in Lu Xiaoqian's hands do not need to be connected to charge with electric energy, their magic mobile phone is directly charged with light energy, and although the prince in their hands has powerful functions, the body is similar to an ordinary mobile phone, using ordinary electric energy, and thinking of that, Ye Yun suddenly remembered that You can actually have two more batteries on their bodies, and it would be good to replace the battery directly when the battery is out of power.

After getting Ye Yun's reminder, You Suo seemed to bring the spare battery with them when they went home, and when You Suo went back to get the battery for them, Ye Yun and Sun Wukong used the stealth function to stealth and then went straight to Mr. Fan's house, but unfortunately they pounced, and Mr. Fan was not at home.

Although Mr. Fan was not at home, Ye Yun and the others still went to Mr. Fan's house to search to see if they could find any useful information, and then waited for them by the way.

Mr. Fan's home is also in a villa community, but it is not a community with Ye Yun, and although this community is not as good as the community where Ye Yun is located, the decoration of Mr. Fan's villa is more luxurious than Ye Yun's villa, just like the ancient palace, extremely luxurious, the floor is all white marble, the dishes and chopsticks are gold and silver, and the tables and chairs Ye Yun are also made of high-quality wood, a set is estimated to be no less than hundreds of thousands, plus some chandeliers and the like, the decoration of this villa is estimated to be tens of millions, This is still without counting some furniture and appliances.

Although Mr. Fan's home was very luxurious, Ye Yun and the others didn't care too much about these things, and after entering the villa, they searched separately, and Ye Yun was assigned to the study on the second floor. Although this Mr. Fan is rich and unkind, and he is in arrears of wages, his study has a lot of books, and the entire two tall bookshelves are filled with all kinds of books, and the recipe for the Bull Demon King's Immortal Pill is known from a literary work.

Maybe the Bull Demon King was too confident, Ye Yun just entered the study and saw a somewhat yellowed book on the table, with some expectation, Ye Yun walked over and picked it up, turned to the page where the bookmark was, and after carefully reading that page, Ye Yun directly used mana to shake the book into powder, because what was recorded on that page was the prescription of the Immortal Pill and the extraction method of the mysterious energy from the center of the earth, and the reason why the Immortal Pill could make people live for 10,000 years was that the mysterious energy from the center of the earth played a decisive role.

In addition to the formula of the elixir, Ye Yun also found a secret compartment in the study, and there was a porcelain bottle and a small notebook that recorded in detail how to refine the elixir, and in the end, Ye Yun also smiled unceremoniously at these two things, that is, the pills in the porcelain bottle were a little less, only five.

In addition, Ye Yun didn't find anything more, and he didn't know where the Bull Demon King went to collect the sap, but these days, Ye Yun has been letting No. 9 pay attention to Mr. Fan's movements, and he also knows a rough range of where he is going.

After meeting with Lu Xiaoqian, who had nothing to gain, Ye Yun gave the approximate range of activities of the Bull Demon King during this time, and when they met with Yousuo, a group of people killed the general location given by Ye Yun, and then searched separately, but unfortunately, they only found the place where the Bull Demon King collected the sap, and did not find the Bull Demon King.

Just when everyone was at a loss, the stupid girl suddenly thought that the Bull Demon King refining the Immortal Pill wanted to reach the center of the earth to collect mysterious energy, then he would definitely find an extremely deep cave crack, plus the Bull Demon King entered the center of the earth to collect energy, it would definitely have an impact on the earth's crust, resulting in abnormal plate activity in which area, and the idea of the stupid girl was approved by everyone as soon as it was said, so Ye Yun and the others began to use the magic mobile phone in their hands to access the network, looking for information about the abnormal plate activity during this time, In the end, Ye Yun and they really found it, and when Ye Yun and they saw that location, they were all silent, and their faces were a little strange, because that location was in the island country.

"You said that if we fight with them, will the island nation sink?" was silent for a while, and finally it was Lu Xiaoqian who spoke first to break the sudden weirdness

Silent.

"This, it shouldn't be, after all, we won't fight directly underground, otherwise the land of Huaxia will also be affected." Ye Yun replied a little uncertainly, after all, no one can say for sure about this kind of thing.

"Why don't you care about him so much, when the time comes, we will lead Lao Niu out and do it again, it will be fine, and besides, even if something dies, it is not our people, what are you worried about, it's so decided, hurry up and set off with my old grandson." After Sun Wukong finished speaking, he jumped on his knees and flew away directly, Ye Yun hurriedly followed when he saw this, and Lu Xiaoqian and they glanced at each other and hurriedly followed.

After waiting until the place, Ye Yun and the others found that there was a small island with a radius of four or five hundred meters that showed that there was an abnormality, and the trees on the island were luxuriant, and judging from the detection of the nineth, there was an extremely deep cave near the center of the island, and there was no end at all, and Ye Yun sensed a trace of mysterious energy from the entrance of the cave that had not yet dispersed and was exactly the same as in the Immortal Pill.

"Looks like this is it, but how can we lure the Bull Demon King out? We can't just wait here all the time for him to come out, can we? The matchmaker in Lu Xiaoqian's hand also checked the mysterious energy at the entrance of the cave and confirmed that this was the entrance of the Bull Demon King to collect the energy of the center of the earth.

"I have a solution, and it's a bit of a risk." Ye Yun looked at Lu Xiaoqian and said.

"What's the solution?" Lu Xiaoqian and the others asked in unison.

"The solution is very simple, that is, Xiao Qian, you go down directly, pretend to probe the abnormal movement of the plate, and after seeing the Bull Demon King, you will turn around and run directly, lure him out, and we will use the stealth function to ambush him outside the hole, after all, you have a magic mobile phone The Bull Demon King knows, he should not suspect it, but Xiao Qian, if you go down, it is easy to encounter danger." Ye Yun said solemnly.

"A little danger is nothing, and there is a stupid girl in my place, okay, I'll go down." After Lu Xiaoqian finished speaking, he waved his hand and jumped directly from the hole more than two meters wide.

After Lu Xiaoqian jumped down, the stupid girl also jumped down after him, and looking at the figures of the two of them who disappeared quickly, Ye Yun and the others hurriedly hid in the bushes next to them, and activated the stealth function of the magic phone, and concentrated on the entrance of the cave.
