"What weapon is the most powerful in Zhao State? The mechanism we encountered in a while may be related to Zhao Guo's weapons" Chi Ling thought for a while and said, according to Zhang Jingyang's previous inference, the next mechanism they will face may be related to Zhao Guo's weapons.

The two girls looked at Zhang Jingyang, wanting to get an answer from his mouth, after all, the previous inferences came out of his mouth, and the latter still had some research on the history of the Warring States Period, maybe it would be useful.

"I don't know" Zhang Jingyang nodded and said helplessly, he does know a lot of Warring States history, but it is all about some celebrity deeds and items at that time, because he only needs to master these two is enough, knowing the history of celebrities is convenient to know who the tomb owner is to determine the dynasty, knowing the value of the items is to pick the valuable things in the tomb to take, this is what they learned upside down, as for what happened in that era, he knows and does not need to be clear.

"The most powerful thing in Zhao is not what weapons, but their army" Li Zimu said lightly, the most powerful thing about Zhao is not in weapons, but in the overall strength of their army.

First of all, they have many veterans, Zhao Hao, Li Mu, Lian Po and so on, these veterans are very good at training the army, so the overall strength of their army is stronger than that of several other countries, and more importantly, after the Hufu cavalry and archery strategy began, their army became an army with cavalry and archers as the main body, which is much stronger than the other six countries with infantry as the main body.

Could it be that this time it is a bow and arrow again? Li Zimu thought to himself, raising his feet and walking slowly forward little by little, every step was cautious. They don't even know what this coming mechanism is.

One step, two steps, three steps, four steps.

More than ten minutes passed, and the four of Li Zimu only walked a distance of more than ten meters, but this distance did not touch a single mechanism, and everyone couldn't help but wonder in their hearts.

"Hmm, isn't there a mechanism? shouldn't it......" Zhang Jingyang said to himself suspiciously, if according to the previous law, if the distance from the mural is less than ten meters ahead, there should be a mechanism, but now they have passed more than ten meters of the Zhao Qian mural, and there is still nothing happening, does it mean that there is no mechanism here at all? Or that there is a mechanism, but they are lucky that they did not trigger it, so they passed by.

"Isn't it good to have no mechanism?" said with a heavy sigh of relief, she was frightened when she walked for more than ten meters, and only dared to follow Li Zimu and walk on the footprints he had stepped on before. Now Zhang Jingyang told her that there seemed to be no mechanism, and it would not be such a waste of time if she knew it earlier......

"Don't you see something different about this place?" Just as the spirit relaxed, Li Zimu frowned and said, he had already discovered from the previous time that the place where they were standing now was different from the place they had walked before.

"It seems to be really different, there is a layer of sand on it" Hearing Li Zimu say this, Zhang Jingyang shone the flashlight on the ground and squatted down to grab a handful of sand and said, the sand is still dry, and it leaks out little by little along the fingers.

"Not only that, this road is different from the road we took before, the previous road was paved with stone slabs, and the road here is indeed paved with gravel," Li Zimu said lightly, from the time he came in and walked here, he remembered clearly what he had seen and seen, and he would never make a mistake.

"Uh...... I don't remember it that clearly...... So what do we do now? Do we continue to move forward?" Chi Ling said helplessly, who would have nothing to pay attention to this small detail? Only a person like Li Zimu, who has to do everything best, would be so comprehensive.

"You retreat to the original stone road, I'll try first," Li Zimu said without replying, they just walked on the gravel road less than two meters, and there was no problem in retreating.

"How's that going to work? in case you ...... What should we do if something happens to you?" Chi Ling vetoed, Li Zimu risked her life for their safety, she would never agree.

"Thinking too much, I'm just afraid that something will happen to you" Li Zimu turned his head and glanced at her and said lightly, he is confident that he can be safe and sound, and it may not be necessary to bring two oil bottles, maybe he will not have time to save people and he will stay alone in the end.

Looking at Li Zimu's eyes that did not give people the slightest refutation, Chi Ling swallowed the words that originally came to his lips again, took Wang Xueling's hand and walked back obediently, standing on the original stone road.

Zhang Jingyang thought about it and retreated, he still had confidence in Li Zimu's skills, if he followed, it would become a burden, it was better to stay and protect the two girls.

Seeing that the three of them had retreated to a safe area, Li Zimu continued to walk slowly towards the front, maybe he was too cautious, right? Li Zimu thought to himself, but he did not doubt the correctness of this decision in the slightest, because two thousand years of experience told him that it was absolutely not wrong to be cautious.

He continued to walk forward for a distance of three or four meters, and still didn't see any changes around him, but Li Zimu didn't slacken, and still walked forward one foot at a time.

"Why did he stop?" Chi Ling asked suspiciously, looking at Li Zimu who was standing motionless in the distance, he was still walking slowly before, but now he stopped directly.

Not good!

A dangerous thought rose in Li Zimu's heart, and he wanted to run forward quickly with his feet and rush across this section of the road. Because he sensed something was wrong.

This place seems to have moved just now!

A slight sound of gears turning sounded, which was particularly abrupt in this quiet environment.

"Li Zimu, run!" the spirit suddenly shouted loudly, his voice full of anxiety, and even a little crying. Because she found that the road before was starting to collapse!

At the same time as the spirit shouted, Li Zimu also began to move, only to see his body bow slightly, ready to start rushing forward, but his feet slipped violently and his body lost its center of gravity.

This damn sand!

Li Zimu's heart tightened, he was about to start rushing forward, but he ignored that there was a layer of dry fine sand on the ground, and the lack of friction between the sole of his shoe and the ground made him slip and almost fall.

But his heart was very calm, Li Zimu quickly stabilized his center of gravity, and with a sweep of his feet, he pushed away all the fine sand on the ground and prepared to exert force again, but it was only delayed for less than two seconds.

It's just that what he didn't expect was that the road in front of him also began to collapse rapidly towards him! Both sides collapsed towards the middle at the same time, and the place where Li Zimu was standing at this time was exactly in the middle!

Looking at the figure that fell quickly along with the road, Chi Ling cried anxiously.
