Li Huai crossed the Yellow River with Concubine Liu, and he didn't know Qi Yuanbai's current location, but he could roughly deduce a range.

According to the predetermined plan, when the war began, Qi Yuanbai would lead his army from the south of Jingtai to attack and advance south along the Yellow River Valley.

The plan was to capture the two locations of Shangzhuang and Xiazhuang, and as for Shangtan, it was an opening deliberately left by Li Huai for Chun Yuyue.

There is a saying in the book of war: Circle three and put one.

Its main purpose is to prevent the enemy from jumping over the wall and adding casualties that could have been avoided.

To avoid plunging directly into the enemy camp, for the sake of safety, Li Huai decided to go to the vicinity of Shangzhuang to look for it first.

Along the way, Concubine Liu didn't pretend to be tired, couldn't walk, was unwell and other excuses, and deliberately slowed him down, which was quite surprising.

He also thought of various countermeasures for this reason, but he couldn't use it, and he was a little disappointed.

The next night.

Li Huai and Concubine Liu stood on the top of a mountain, Li Huai took out his binoculars, glanced ahead, and after making sure that there was no one, he was ready to go down the mountain to the official road to take a look.

"Why do you always like to look through the tube?" Concubine Liu was curious all the way, and finally couldn't help but ask.

"You say this?" Li Huai took out the binoculars, handed them to her, and said, "You can see it clearly at a glance yourself." ”

Concubine Liu took the telescope very suspiciously, followed Li Huai's example, and looked ahead.

Brush!

Anyone who has ever used a telescope knows that looking through a telescope gives people the feeling that the vista is not magnified, but that the vista is suddenly being pulled closer.

Concubine Liu experienced this visual impact for the first time, and was naturally shocked, but after all, her mood was different from ordinary people, and she quickly adapted to it.

Then she had a new problem.

"Why can this thing be seen even at night?"

In a state where cultivation is not used at all, the perception ability of martial artists and ordinary people is actually similar.

But a martial artist is a martial artist after all, and he often improves his perception ability, and slowly derives a subconscious instinct.

That is to say, I can feel the murderous and cold aura...... And so on, in fact, they are all self-protection consciousness.

The current Concubine Liu is almost the same as an ordinary person, and some of her perceptual abilities naturally can't be exerted.

For example, the night in her eyes is almost the same as the night seen by ordinary people at this moment. However, she is still very sensitive to 'qi'.

However, now through the telescope, she can see the dark night that can only be seen clearly with a state of cultivation, which makes her very magical.

"Because the beam collected by the objective lens is much thicker than the pupil, and the purpose of the telescope is to magnify the details." Li Huai explained lightly.

"What...... Meaning? ”

Concubine Liu was full of question marks, and she could hear these words clearly, but when they were connected, she couldn't understand them at all.

It's hard to explain.

"For example, the pupils of our eyes are only so large, about half an inch and a half, and the beam that passes through is only half an inch and a half."

"Now collect light through this objective."

Li Huai pointed to the big lens in front of her and continued to explain, "The light it collects is very coarse, and then this very thick beam of light is sent into our eyes, so we can see some faint scenery." ”

"Dim view?" Concubine Liu repeated his last sentence with a thoughtful expression.

"In fact, there is no absolute darkness in the world, nothing can completely absorb the light, so there is a reflection, you know the mirror, the scene in the mirror, in fact, is the effect of the light being reflected."

Concubine Liu nodded obediently.

Li Huai continued.

"But after all, our human eye ability is limited, and we can't see very far at night, nor can we see very clearly, so some scenes will be ignored by our eyes, but as long as we magnify it, or strengthen the light, we can see everything."

Concubine Liu didn't understand it for a while, but she was really smart and receptive, and he thought about it according to Li Huai's words.

Suddenly I noticed a problem.

"You mean that what we see with our eyes is the light emitted by objects, not what our eyes see?"

This discovery.

For her, it was extremely shocking!

Not to mention all people, at least in ancient times, many people subconsciously thought that it was the eyes that saw things, not the light of things that came into view.

Li Huai nodded very naturally, "That's right." ”

"How do you prove that the light emitted by the object is real, and not a false vision?" Concubine Liu asked.

"Uh......" Li Huai was stunned, he was indeed embarrassed by her, and after thinking about it, there seemed to be a way to prove it.

"You can touch it with your hands, it's like a blind man, and you can't see anything, but you can know the shape of an object by feeling it with your fingers."

"Is this feeling coming from an object, or is it something we feel ourselves?" Concubine Liu then asked.

"Of course it's from an object, it doesn't seem right, it should be felt by the fingers, or it's not quite right." Li Huai didn't know how to explain it.

Concubine Liu didn't care about this, and continued to think along the train of thought.

"If it's the feeling that the object conveys to us, then how can we prove that this feeling is not deceiving?"

"If we see that it is round, will it actually be square? When we touch a square, will it actually be round? ”

"Must the heavens be above, and the earth must be below?"

"How is it determined that it is up and down, left and right, front and back?"

"Our world, will it all be fake?"

She literally incarnated into a hundred thousand whys, and I don't know where she came from with such many questions.

Li Huai was completely confused, these questions were not at all something that normal people could come up with, nor could they be answered by normal people.

He simply quickened his pace a little, wanting to hurry up to the official road.

Concubine Liu also quickened her pace, chased after him, and asked him another question, "Now there are only you and me here, how can you prove that I am real by your side, will you also be fake in front of me?" ”

Li Huai suddenly stopped, Concubine Liu also braked sharply, and the two looked at each other for a long time.

Chirp!

Li Huai raised his hand and pinched her cheek and asked her, "Does it hurt?" ”

Concubine Liu nodded, "It hurts." ”

"Only pain is real, because pain needs to be endured and suffered. If you still insist on asking me similar questions, this is my answer. ”

After Li Huai finished speaking, he turned around and continued walking.

Concubine Liu was stunned for a moment, touched the place where her face had just been pulled, and muttered: "The pain is real, isn't the joy real?" ”

"What is true? What is false? ”

Concubine Liu was stunned for a while, and when she woke up, she found that Li Huai had gone away, so she hurriedly chased after her, but she hadn't spoken yet.

"Shut up!"

Li Huai said sharply.

Hum!

Concubine Liu couldn't help but snort coldly, she especially liked to talk to Li Huai, because what she said, Li Huai could be right with her.

Usually her words, few people pay attention, and the people who scold her, no matter what she says, they will echo her.

The rest of the people often see her as crazy.

Only Li Huai will hear every word she says and every question she asks, and then answer it after thinking about it.

This kind of psychological change is usually not felt by oneself.

They came down from the mountains.

There are deep reel marks on both sides of the official road, and the leaves on the road are very messy, and the imprints are covered with a thin layer of ash.

At least three or five days ago.

"So fast?"

Li Huai was secretly surprised, Qi Yuanbai had obviously taken Shangzhuang and had already gone to Xiazhuang.

Xiazhuang was the focus of the defense of the Gaochang royal army.

I don't know how the battle went.

"We have to speed up, I can't lose this war," Li Huai was halfway through speaking, and suddenly reacted and told her what ...... was doing.

"Let's go!"

Li Huai spit out a word and began to travel south with Concubine Liu.

Concubine Liu couldn't help muttering, "I knew this, I had crossed the Yellow River before, and I should have gone directly to the west, maybe this will be the time." ”

How many wrongful roads have been taken.

She can't exert any cultivation at all now, and unlike a monster like Li Huai, she not only exercises qi, but also exercises her physique.

The continuous trek is very tiring!

"If you can't walk, just say it, don't hold on, I can carry you." Li Huai said lightly.

Because there are mostly mountain roads on the west side of the river, when crossing the river, I didn't bring the little white dragon and handed it over to Hua Qingyue.

They can only walk on their legs.

When Concubine Liu heard this, she disdained it, the dignified Archbishop of the Yang Palace, does she need someone to carry it?

She is not anyone's grandmother.

After another day of rushing like this, Li Huai planned to rest for a while and eat something to replenish his strength.

Sleep for an hour before continuing on your way.

Who knows.

During this break, Concubine Liu could hardly stand up, but she didn't say anything, she gritted her teeth and held on, and followed Li Huai's faster and faster steps.

Finally, when he encountered a rock, he couldn't lift his foot, kicked it on the stone, and fell down.

Li Huai turned around and looked at Concubine Liu, who was writhing on the ground, and wanted to stand up.

Slightly surprised.

He squatted down and touched her calf, the muscles were completely tense and almost broken.

He flipped her over.

"Don't move!"

Li Huai said two words in a deep voice, then picked her up, put her on the grass next to her, and reached out to drag her shoes and socks.

"What are you doing?"

Concubine Liu suddenly panicked.

"Look over there, what's that?" Li Huai pointed behind her.

"What?"

Concubine Liu subconsciously turned her head, but she didn't see anything, thinking that she hadn't looked carefully enough.

Take advantage of this opportunity.

Li Huai took off her shoes.

"Ahh

A scream.

Concubine Liu's face turned white in pain, hugging her thighs, pumping cold air, and she couldn't say anything painful.

Li Huai looked at her bloody jade feet, socks and rotten flesh, almost all mixed together.

How did she endure this kind of pain until now?

Li Huai was more curious about one thing.

"You're also a great grandmaster, so fragile?"

Concubine Liu suddenly felt a little aggrieved, obviously he was in a hurry, and it was very difficult for her to catch up.

"I have the golden needle of the thousand-faced lady in my body, and my cultivation has not been recovered, so I can only use all the power in the meridians to suppress the golden needle."

Otherwise she would have died.

She didn't say that.

Li Huai didn't mean this either, and asked again: "I mean, how can your great grandmaster's body be so fragile, and without cultivation, he is really no different from ordinary people?" ”

Concubine Liu understood this time, and said with some disdain: "You mean refining the body, I know, but what's the use of practicing, which one of the physiques can you see who can cultivate to the grandmaster?" ”

Strength is everything.

She won't waste her precious time refining her body, and if she has this space, it is better to practice her True Qi for a while, or enlighten the Dao.

"I haven't seen anyone who has cultivated to the grandmaster, but I know one who has cultivated out of the Mahayana realm by refining the body." Li Huai said with a smile.

"Impossible!"

Concubine Liu said categorically, no matter how much you practice in refining your body, you will not have cultivation, that is to say, even ordinary martial artists can't reach it, at most they are a little stronger than ordinary people.

"You're optimistic."

Li Huai didn't bother to argue with her, facts speak louder than words, and he picked up a stone directly in front of her.

Bang!

With the force of his palm, the stone instantly turned into powder.

Concubine Liu was stunned for a moment, she could feel the qi, but she really didn't feel the qi at all just now.

It is impossible to do this by brute force alone.

Could it be that refining the body can really cultivate to become a grandmaster?

Li Huai still had to hurry, so he didn't bother with her about these things, but said: "Your injury must be treated, otherwise your foot may be wasted, and you don't want to be in a wheelchair for the rest of your life." ”

Concubine Liu didn't resist this time, "Will you cure it?" ”

"I've learned a little bit from Yule." Li Huai saw that there was no suitable thing nearby to replace him, so he drew his saber.

It was handed to her.

"What?" Concubine Liu was a little puzzled.

"If you bite the hilt, it won't hurt so much." Li Huai explained.

"Cut!"

Concubine Liu snorted coldly, "I don't need it." ”

Forget who screamed just now?

Li Huai didn't persuade her either, so he conjured up a blood arrow, transformed into the shape of a knife, and then controlled the knife to cut her socks little by little.

It doesn't hurt at all.

Concubine Liu's heart was also put down.

As the knife went down little by little, it began to approach the wound, and Li Huai had to separate the socks from the rotten areas before they could be treated, otherwise the cotton silk of the socks would remain in her feet.

This step is unavoidable.

Just a moment.

"Whew!"

Concubine Liu almost grabbed the knife and bit it tightly, and there was a faint whining sound in her mouth.

You tap ...... Hurt! Slow...... Slow down......"
