In Wu Yan's heart, heaven and man are at war, and he puts himself in a desperate situation in order to help others, which is something he will never do, and after three years of cultivation in the last days, such a rotten good person has long been dead.

When he was proud of the Jianghu plane, in the face of such a choice, Wu Yan knew what to do without the slightest hesitation.

However, today, faced with such a choice again, Wu Yan felt that it was difficult to make such a choice due to the war between heaven and man.

On the one hand, it is its own principles of doing things, and on the other hand, it is the thoughts in your heart.

In the last three years, it is indeed possible to change a person, and Wu Yan's mind at that time, which was changed by the environment, was indeed suitable for survival in the last days.

It's just that after crossing the heavens and worlds, this is already the fifth time that Wu Yan has crossed, and after staying in these ordinary worlds for five years, Wu Yan's heart has unconsciously changed.

"Am I really sorry that Liu Jinyuan will die?" In Wu Yan's heart, for the first time, he questioned his original firm principles of doing things.

Thinking of Liu Jinyuan's gentleness, thinking that the master and apprentice are actually friends, and thinking that the reason why Liu Jinyuan was caught by the Moon Worship Sect Master today was mainly because of himself.

"Hey, surnamed Wu, what are you thinking about?" , Wu Yan hesitated, and Lin Yueru next to him naturally saw it in his eyes and asked.

It's incomprehensible, as the master of Jin Yuan's cousin, and he can defeat the Moon Worship Sect Master himself, why would he save someone and still have a mother-in-law? What the hell was he worried about?

Lin Yueru's words made Wu Yan's body shake slightly, and immediately, he sighed helplessly.

Alas, over the years, he has changed after all, and if he thinks differently, if he is arrested, Liu Jinyuan will definitely go out of his way to save himself.

"Okay, I'll go alone on the trip to Nanzhaoguo, you can stay......."

After struggling for a long time, Wu Yan finally felt that he should follow his inner thoughts, so he immediately nodded and agreed, and said to Lin Yueru.

Before, he followed his own principles of doing things, even if he saw Lin Pingzhi being killed, Wu Yan would not have the slightest psychological burden.

But now, Wu Yan knew that if he really sat back and ignored Liu Jinyuan's affairs, he would definitely feel guilty for a long, long time.

In this case, it is enough to save others yourself.

Besides, according to Wu Yan's understanding of the Lunatic Master, the purpose of the Lunatic Master is for himself, and the main purpose is to discuss scientific knowledge with himself, not to kill himself.

"No, I'm going with you too!" , It's just that for Wu Yan's words, Lin Yueru shook her head firmly.

"When Jin Yuan's cousin was arrested before, I had the task of coming back to report the news, so I sat back and watched him be arrested, watching others endanger themselves but being greedy for life and afraid of death, this is not my Lin Woman's personality."

Lin Yueru looked at Wu Yan seriously, her delicate face was full of determination, and when she said this, she paused slightly, and said, "If you really want to leave me, I will go even if I am alone!" ”，

"Do you know, if I really do it, I don't have the energy to take care of you", sighed helplessly in his heart, Wu Yan stared at Lin Yueru seriously and asked.

"You don't need to save it! Life and death! With a wave of her hand, Lin Yueru didn't seem to have her life and death in her heart at all.

Well, that's all said and done, and Wu Yan has no way to persuade Lin Yueru to stay.

Shaking his head, after informing the people of Shushan, Wu Yan and Lin Yueru went down the mountain together, and then quickly rushed in the direction of Nanzhao Kingdom.

……

Nanzhao Kingdom, Lunatic Worship.

These days, Liu Jinyuan has been under house arrest in the Lunatic Cult, but although the Lunatic Sect Master is the ultimate boss of the Sword and Fairy Legend, he is not an evil person by nature, and he is polite when dealing with people.

Therefore, although Liu Jinyuan was under house arrest, as long as he did not leave within the scope of the Lunatic Cult, the Lunatic Sect Master did not restrict Liu Jinyuan's personal freedom.

From Elder Shi's mouth, Liu Jinyuan certainly knew what the Moon Worship Sect Master had done in Nanzhao Kingdom, and he also knew that Li Xiaoyao and they would inevitably fight with the Moon Worship Sect Master in the end, so since he was under house arrest here, Liu Jinyuan simply walked around and carefully investigated the situation in the Moon Worship Sect.

Maybe if you really fight in the future, you can know yourself and your opponent to the greatest extent.

The Lunatic Cultists all stared at Liu Jinyuan, and did not stop him from wandering around.

The sect leader said that Liu Jinyuan's son is the sect leader's honored guest, as long as he doesn't leave, he can go wherever he wants, and even the food and clothing must be as fine as possible.

After taking a big tour of the place of the Lunatic Worship, Liu Jinyuan immediately followed him to a courtyard.

After walking in, he found that the Moon Worship Sect Master and several disciples were busy, but Liu Jinyuan felt that they couldn't understand what they were busy with.

It turned out that a large water tank was placed on the ground, and a carved line was drawn at the water level, and then, a sturdy Lunatic cultist, carrying a large scale, was weighing the large stone.

After writing it down, he soaked the big stone in the water tank and weighed the weight of the big stone in the water.

Then, after lowering the scales, another Lunatic cultist took out the water from the water level that had risen due to the soaking of the stones, and returned the water level to its previous carved position, weighing the water......

If anyone with a little knowledge of physics in modern times sees this scene, I believe they can understand what the Lunatic Master is doing, he is measuring the buoyancy of this large stone in the water.

Moreover, the relationship between the buoyancy and the volume of this large stone is being calculated.

It's just that although Liu Jinyuan has read more than 10,000 books, of course he doesn't understand these modern physics knowledge, so when he saw the busy work between the Moon Worship Sect Master and these disciples, he looked confused throughout the whole process, and he didn't understand what they were doing at all.

"Well, sure enough, Mr. Wu is right, the buoyancy of the object in the water is related to the volume of the object, and when the buoyancy obtained by the volume of the object is greater than the specific gravity, it can float on the water."

After carefully measuring and calculating the relationship between these buoyancy and volume, the Lunatic Cult Master nodded secretly.

Once again, he verified the answer to a question that he casually asked Wu Yan why the boat could float on the water, but the stone sank to the bottom.

"Liu Gongzi ......".

After the busy matter came to an end, the Moon Worship Sect Master's eyes fell on Liu Jinyuan's body and said, "Can you see it?" ”。
