Looking at the devastated surroundings, Lu Yu also didn't expect that he and the other party could actually cause such destructive power with just a tentative blow.

But fortunately, it was just a temptation, and Lu Yu didn't use too much strength, which caused the other party who was a demon to be arrogant and only used similar power, which didn't cause more casualties.

"Human, leave your name, you have the qualifications to make the demons face up. With the same words again, the windless robe trembled, and a wave of energy followed.

"Be careful. Lu Yu's body moved, and in just an instant, he flashed in front of the qi path that the other party just caused at random, and with a wave of the seven-star sword, the qi suddenly disappeared.

Lu Yu, who had dispersed his energy, did not look back, but said in a low voice: "Quickly lead the army away from here." ”

The knight hesitated for a moment, but heard the old man say the same: "Listen to him, now nearly half of the army has lost its combat effectiveness, and staying can only become a drag." ”

Although they didn't want to admit it, Lord Knight knew that this was the truth, and Lu Yu, who had the blessing of ten thousand battle qi, had indeed exceeded their original understanding of the power of battle qi.

"The army retreated with the wounded and the sick. The knights, still in unison, turned their horses and retreated into the distance.

"Why, as a demon, didn't you come to ask for the sojourn, didn't you stop it? Lu Yu was always vigilant against the other party's possible attack at any time, but the other party did not take the slightest action until the cavalry retreated several kilometers away.

"Now that the sojourn has been cleared, there is no point in killing the remaining people, but there are things that interest me more at the moment. ”

"These sojourners don't seem to matter so much to you, it seems that the appearance of those diseases is not caused by you, but why do you come here to ask for these patients, just for interest? Lu Yu was also puzzled.

"Actually, you should have some guesses, after all, you don't belong to this world. The demon's words surprised Lu Yu.

"I see, are these diseases from another world, so why should we fight!" Although the long sword raised again had many questions, Lu Yu didn't have time to ask.

"No, you've lost the right to fight demons, let's go, human, remember, the only way to communicate with demons is great power. After the demon finished speaking, he flew directly into the sky, but he turned into an evil dragon again and flew into the distance, and the overwhelming demons also followed.

"Hehe, have you seen through, Momo, a strange creature, but it seems to be completely different from the two people with demonic energy I met in the martial arts world. "The demon who left casually, finally no longer has to pretend, in fact, from the first temptation, Lu Yu found that the external battle qi has been constantly draining.

After all, it's not your own power, even if you can use it, you can't keep it for a long time, just a touch will make the battle qi pass faster, maybe even the old man didn't think of it.

"It's okay!" The old man looked at Lu Yu who came with his head down and asked with concern, in fact, there would be a demon this time, even he didn't expect it, the demon is a creature above humans in this world, and it is completely different from the secondary demons.

"It's okay, the demon is gone on his own. Then Lu Yu told the old man all the questions he had just asked.

The old man also frowned when he heard this, "As I thought, the demon is a proud creature, and he thinks he is above all things, but he should not do such a thing, if what he said is true, then the most urgent thing at the moment is to find the source of how these patients are infected with parasites." ”

Lu Yu sighed secretly when he heard this, it seems that his recruitment this time is far from being as smooth as last time, obviously, if he doesn't help the old man find the source of these parasites, the old man is afraid that he will not leave with him.

"What is this. Just thinking about how to deal with this matter, Lu Yu suddenly raised his right hand.

A malt-like gaseous object swirled in the palm of his hand.

"The little brother is really not an ordinary person, he can actually get the seed of battle qi from an outsider, this seed is the source of everyone's war qi, but most people are inspired by the battlefield, and it is rare for someone like you to be like an inheritance. In fact, in the old man's words, Lu Yu knew that although this Fighting Qi Seed was the source of the generation of Battle Qi, not everyone would get the Battle Qi Seed after stimulating the Battle Qi.

Because only by forming the seeds of battle qi can the battle qi be promoted to a higher level, for example, the tens of thousands of knights present, although all of them have battle qi, but there are very few who can condense the seeds of battle qi.

"I see, the kid has been taught, but I think maybe the kid was able to obtain the battle qi seed because of the previous innate true qi in the kid's body. Just as Lu Yu said, as Lu Yu injected a wisp of innate true qi into the battle qi seed, the battle qi seed that was originally just gently suspended above Lu Yu's palm suddenly spun faster, only to stop after a while, but vaguely everyone could see that this battle qi seed had obviously become larger, although it was not obvious.

It seems that this innate true qi does have the ability to enhance the battle qi, but Lu Yu only has such a trace of innate true qi left, these innate true qi is not his own power, and now it is completely lost, although there is a big hole card missing, but it also has a lot of hidden worries, and it also makes the seven-star power completely liberated, this seven-star power is formed by seven different gems absorbing the power of the Big Dipper to escape heaven and earth, maybe if he can separate the seven-star power that is fused together and inject it into the seven gems that can accommodate the strange power, maybe the seven-star sword will be restored with this。

However, at the moment, Lu Yu's primary problem is to help the old man deal with the parasite, but he still has no clue about everything, and he can only wait for the patient to wake up and inquire before making plans.

The symptoms of these patients were very rare in Lu Yu's previous opinion, but it was obvious that the old man's ability was also rare, just relying on the talisman and the talisman to completely eliminate the parasites that lived in the hermitage.

There is no shadow of any common medical skills at all, but some people who lie to people everywhere in the future that Fu Shui can save lives is like the reincarnation of the so-called great gods.

Perhaps he didn't like the crowd, but the old man didn't choose to return to the station with the many knights, but instead built a simple wooden house nearby and settled down.

And those patients also quickly regained consciousness after a day of continuous treatment by the old man, but they did not get any usable information from their mouths, except for feeling weak and dizzy for a while, and then there was nothing to remember.

"Ge Xianweng, I really don't know why I got this strange disease, to be honest, if I hadn't been rescued by you this time, maybe I wouldn't even know that I had this Rausch infectious disease. The villager's words were accurate, and his expression did not seem to be a lie at all, which seemed to others to be the behavior of a person who did not understand anything and suddenly learned what was going on.

It's just that obviously Lu Yu doesn't think so, this kind of performance is only available in TV series and movies, and the reason is because the actor already knows how to express it, which is performance.

After several patients were carefully questioned, they left, and Lu Yu also knew the old man's name - 'Little Immortal Weng', Ge Hong.

"What do you think!" This sentence has the meaning of taking the school examination, as a doctor, he is naturally more proficient than ordinary people in seeing people.

"Maybe we can start with that source. ”

"Yes, this man, though he knew nothing as they did, had overlooked the point that he was present in the accounts of others, but rarely in others, and that he had told them when and where they had met. ”

"My lord, so my subordinates will send someone to follow this person. ”

"No, you're going to be too conspicuous. "Ge Hong's words are not wrong, the battle spirit is a kind of indomitable killing spirit, very determined, and even deliberately hiding it can't be done.

"I'll take care of that. Lu Yu also volunteered at the moment.

Looking at the departing Lu Yu, the knight said, "My lord, are you so relieved of this person." ”

"Lei Jun, if one day I am gone, remember to go to my hometown, and believe that my disciple has no less ability than me. ”
