"You understand the story of the drop stone, right?"

As soon as these words came out, not to mention Zhuge Liang, even Zhou Tai nodded, and instantly understood Shi Xin's tactics.

It's easy to say, it's a stupid method, with the power of six people to knock on the same place without sleep, and one day it will be able to knock open.

Zhuge Liang first asked: "Lord, don't look at the outer layer of Xuanwu without the true qi of the body, in fact, its protective true qi has been fused with the tortoise shell. In other words, we have to break not only the tortoise shell itself, but also its protective true qi. ”

Shi Xin nodded, "I know!"

"Then here's the problem. Xuanwu is a god, and its protective true qi can be said to be endless, with our limited strength, can we compete with it?"

Shi Xin guessed, "I think, since the gods are testing us with three successful powers, the recovery speed of true qi is also in a state of three percent, right?"

After speaking, he looked at Xuanwu.

The snoring continued, and there was no response.

Zhang Ning tugged at Shi Xin's sleeve, pointed to the back, and said in a low voice, "Lord, look." ”

It turned out that Xuanwu's tail was swinging up and down, which should have affirmed Shi Xin's words.

Everyone thought it was funny, and he was listening to everyone, but he was pretending to be sleeping, and he was really an old man with a strange temper.

This problem is solved, and Shi Xin said: "Now there is only one last question left, can Ning'er's wooden barrier be open all the time and restore our strength?"

In order to maintain the highest intensity and non-stop attacks as much as possible, Shi Xin divided all the personnel into three groups, he and Zhou Tai in one group, Zhuge Liang and Zhao Yun in one group, and the two groups attacked in turn.

Cai Yan and Zhang Ning are in a group, if there is a situation such as escalation, injury, and lack of strength in advance, one of them can also be replaced.

Cai Yan's Phantom of the Green Knife and Zhang Ning's Vermilion Bird Sword and Green Dragon Sword, although they are a little worse than the above, are not too much worse, basically the same as Zhou Tai.

Zhang Ning's other main duty is to use the wooden enchantment blessed by the Blue Dragon Sword to restore everyone's strength.

When it comes to physical strength, it is the most basic consumption of the human body, and it is a truth that you have to sleep when you are sleepy, but sleeping is the spirit.

When fighting, everyone consumes True Qi and physical strength, but now that they have been promoted to the ninth and tenth ranks, the speed of True Qi automatic recovery has accelerated, so recovering physical strength has become a top priority.

Zhang Ning heard Shi Xin's question and smiled proudly, "Don't worry, my lord, I've tried it, the wood element contained in the Qinglong Sword is very rich, and it's no problem to recover your physical strength at all!"

Shi Xin gave a thumbs up, "Awesome!"

The plan was set, and the crowd began to act.

"This is it!"

Shi Xin pointed at the tortoiseshell, setting a goal. It was easy to recognize there, the tortoise shell itself happened to have two vertical and horizontal lines intersecting, and Shi Xin set his goal at the midpoint of their intersection.

First, everyone attacked together, and when the true qi and physical strength were halfway consumed, Shi Xin, Zhou Tai, and Cai Yan withdrew to rest, leaving Zhuge Liang and Zhao Yun to continue.

When Zhuge Liang and Zhao Yun were exhausted, Shi Xin and Zhou Tai, who were in full state, rotated.

And Zhang Ning's Green Dragon Sword always floated above the Five Elements Enchantment, and the sword body emitted a faint green light, which was replenished into the wooden enchantment to increase the strength of recovery.

If only one enchantment is released, Zhang Ning's true qi consumption is negligible, sometimes he is sleepy, and he can even take a nap, as long as one consciousness is left, the wooden enchantment can operate automatically.

The six of them are like a sophisticated machine, constantly operating.

On the fourth day, everyone felt that the passage was getting slower.

Doing the same thing monotonously and repetitively consumes everyone's patience. They all looked sad, their eyes were prominent, their bags were deep, and their faces were green.

This is understandable.

Anyone who does this will feel bored, which will cause the state to decline.

This is a typical manifestation of a psychological state affecting a physiological state. It also caused a kind of evil effect, and the true qi and physical strength began to be consumed exponentially, and the attack effect decreased significantly.

During this period, Shi Xin encouraged everyone many times, and the first three days received obvious effects, but on the fourth day, the effect was much worse.

It's no wonder that even Shi Xin feels that he is running out of words.

Come on, try harder, and you'll be successful soon!

What else is there to say? Finally Shi Xin shut up.

And that piece of tortoise shell is still outrageously strong.

"My lord, it seems to be ...... No, I can't!"

Zhuge Liang called Shi Xin aside and asked.

In order not to be heard by others and affect their faith, Zhuge Liang kept his voice very low.

Shi Xin looked at the tortoiseshell and sighed, "yes, it's really distressing. What is Kong Ming's best plan?"

Zhuge Liang shook his head: "If there was a way, my subordinates would have proposed it a long time ago." It's ......."

When Shi Xin heard this, he seemed to have a turning point, and suddenly came to his senses, "What is it?"

"But we can't go on like this, or morale will drop to freezing. ”

"Okay......" Shi Xin laughed, and was about to stop everyone, when suddenly a flash of inspiration flashed in his mind, and he said hurriedly, "Kong Ming, what did you just say?"

"I said morale was at freezing point. ”

Shi Xin looked up at the sky and muttered, "Freezing, freezing......"

Suddenly slapped his thigh and laughed: "I have a way!"

Scratching his mouth and scratching his cheeks, he was overjoyed.

"Let's all stop. ”

Everyone stopped, looking at Shi Xin in confusion.

"I thought of a way to hopefully break the tortoise shell. Everyone rested in place for two hours to adjust their condition. ”

The whole crowd was relieved, and they fell to the ground gasping for air.

It's not that I'm tired, but I can finally leave the state I've been in for four days.

As soon as the mind relaxes, the tiredness quickly leaves the body, and the mind becomes active.

"My lord, what can you do? Will it be like this time, it will be another method like "water drops and stones", and one dozen is four days?"

Zhang Ning hammered his shoulder, and his tone was a little complaining.

But just complain, she has been driving the wooden barrier for the past few days, and she has worked hard.

Shi Xin smiled: "Haha, not this time." And if it doesn't work out this time, we can roll up and leave. ”

Hearing Shi Xin's confidence, everyone rejoiced, and their morale rose.

Everyone replenished some food, closed their eyes and meditated for a while, and became full of energy again.

Two hours passed quickly, and everyone gathered around Shi Xin again to listen to his explanation.

Shi Xin walked in front of the turtle shell, tapped his finger at one of the places, and coughed, "I suddenly remembered the truth that I realized after I was promoted to the tenth rank. Any object that is as low as the temperature is low enough to become brittle. Under this premise, I only need to use my Ghost King Shield, one of Youping's violent fist gloves, and Ning'er's Five Elements Water Enchantment to freeze the entire turtle shell. When the temperature drops, the shell will become brittle, and then we will all bombard it with a special move, not afraid that it will not break. ”

After everyone heard this, they were a little confused.

It's not easy to ask.

After everyone rises to the tenth rank, they will comprehend a deeper level of truth, some about cultivation, some about formations, some about music and rhythm, and so on.

In short, Shi Xin said that it was established, and that was established.

In fact, what Shi Xin said was all nonsense, how could he realize the truth after upgrading, and he used the knowledge of later generations.

Any object, there is a problem of brittleness and hardness.

When cooled, it becomes brittle, and when heated, it becomes soft, which is basic physics knowledge, and many people understand it.

But understanding may not be able to do it, if it weren't for the three of them having the skills to cool down, understanding would be in vain.

Hearing Shi Xin's words, Xuanwu's snoring paused visibly, and immediately returned to normal.

"This old turtle pretended to be asleep when he heard it. But then again, I didn't react to the fight for four days before, does this mean that there is a chance?"

Xuanwu's performance gave Shi Xin confidence.

After the discussion was settled, Shi Xin sacrificed the Ghost King Shield, Zhou Tai used his left hand fist gauntlet, and then cooperated with Zhang Ning's water enchantment, and the three of them took the lead.

The Ghost King Shield and the Violent Fist Gauntlet exuded a cold aura and clinged to the turtle shell. Zhang Ning's five enchantments came out together, activating the "Five Elements Transformation" talent. Among them, the water enchantment is the most dazzling, and the nine-knotted staff is waved from time to time, and with each wave, there is an extra layer of cold ice on the turtle shell, and the ice is constantly strengthening.

It didn't take long for the cold air centered on the turtle shell to emanate and quickly encroach on every corner of the room.

Zhuge Liang once approached the three of them, like falling into an ice cellar, and almost shivered.

After a stick of incense, the temperature of the entire secret room had dropped to zero, and a white mist came out when everyone breathed.

The temperature continued to drop, but fortunately, everyone cultivated to a high level, and all of them had cultivated on the sacred mountain, and they were extremely resistant to the cold, so they would not be invaded by the cold.

But the sudden drop from normal temperature to this low temperature makes me feel a little uncomfortable.

After a while, Zhang Ning's body shook, and he inhaled hissedly, his teeth chattering: "Lord, I'm ...... I can't, it's the lowest temperature achievable. ”

Shi Xin said in a deep voice: "Okay, you step back first!"

"Yes...... Yes!"

Zhang Ning stomped his feet away, his little face flushed with cold.

"Leave the room to escape the cold, and I'll call you in. Shi Xin said.

At this time, a thin layer of ice was formed on the floor and walls, and the thickness extended from the center of the turtle shell. An icy chill permeated the room, and visibility was low.

After the remaining four people went out, only Shi Xin and Zhou Tai were left in the room.

Zhou Tai suddenly let out a "Gege" sound, which was obviously the sound of chattering teeth, but it was quickly taken back by Zhou Tai.

Shi Xin suddenly realized that Zhou Tai's bursting fist gloves had been sticking to the turtle shell, and the low temperature was transmitted to him through the fist gloves.

His third-level Heavenly Cold Divine Power was much higher than Zhou Tai's acceptable range, and Zhou Tai had reached his limit at this time.

"Youping, you can go out too. Leave me here on it. ”

"Lord......" Zhou Tai didn't want to go out, "I can still bear it!"

Shi Xin smiled, "No, it's not a matter of patience. If the temperature of the gloves cannot be lowered, the temperature of the turtle shell will increase. Therefore, you should save yourself some strength and wait for the attack. ”

"Okay!"

Zhou Tai slowly put away his hand and walked out.
