Being able to detect the situation of this secret realm in advance gave him an understanding in advance, thus gaining absolute initiative in the game between Zhang Liang and Zuo Ci.

The only problem is how to exchange information with Zhen Mi.

Although Zhen Mi could "entrust him with dreams", the prerequisite was that he had to fall asleep. Under this situation, it was definitely impossible for him to fall asleep peacefully. He had to think of other ways...

…

About another quarter of an hour passed like this.

Finally, a bamboo raft turned back. This was the raft heading downstream. Although the six soldiers on it were all safe and sound, they did look very tired.

After all, they can go downstream without expending too much effort.

But when I came back, I was swimming against the current, and it was impossible to do it without any effort.

The soldiers who went upstream to explore were just the opposite. It was not easy for them to go, but it was very effortless when they turned back.

But at this moment.

The raft that went upstream to investigate has not returned yet.

This situation is actually not normal.

Wu Liang, who received the education of later generations, was already doing problems similar to this situation when he was very young:

In the same amount of time, if a group of people goes upstream and a group of people goes downstream, if they expend the same amount of effort, it doesn’t take much calculation to know that the group going downstream will have traveled a longer distance.

Then when the people going down the river turn back, it will inevitably take longer because they have to go upstream when they come back.

As for the pedestrian who went upstream at the beginning, because the distance they walked out was shorter, the distance they needed to walk when they came back will be shorter, plus the speed bonus of going down the river when they came back...

No matter how you calculate it, the group of people who went upstream at the beginning must be the first to come back.

But now the situation is exactly the opposite...

"How did you find out?"

Except for Wu Liang, no one seemed to be aware of this rather detailed issue. After bringing the six soldiers ashore, no one raised any questions. Zhang Liang directly called them over and started questioning them.

"Returning to Mr. Zhang, the lower reaches of the underground river actually lead to a deep pit. When the river reached the abyss, it formed a line of white water that splashed vertically down. Fortunately, my subordinates heard the sound of white water in advance and were on guard.

, so we stopped in advance, otherwise if we got closer and the bamboo raft was sucked by the rapids at the mouth, I might not be able to come back."

One of the leading soldiers came forward, raised his hands and said, with an expression of lingering fear on his face.

"Um……"

Zhang Liang nodded slightly, and then asked, "As you go all the way down, did you find any possible place to stay along the way?"

"I haven't found any place to stay. The river seems to be a straight-through cave. I haven't even seen a temporary stopping place."

The soldier said seriously again.

"The only thing we can do is wait for the people who went upstream to investigate to come back and see if they have discovered anything..."

Zhang Liang pondered and glanced at Wu Liang and Zuo Ci, naturally wanting to hear their opinions on this result.

"What Mr. Zhang said is absolutely true."

Zuo Ci stepped forward and cupped his hands and said, "It is not appropriate to draw conclusions prematurely yet..."

However, when he was just halfway through speaking, Yan Lu next to him interrupted Zuo Ci, pointed to the underground river not far away and said, "Master, what do you think that is?"

"?"

Hearing this, everyone looked in the direction he pointed.

It doesn't matter if you look at it.

Just as they were greeting the soldiers from the lower reaches, some foreign objects floated down silently in the river upstream.

These foreign objects are nothing but broken bamboo fragments and residues of different sizes...

"this?!"

Everyone's hearts suddenly tightened and they held their breath.

This is definitely not a good sign, indicating that the soldiers who went upstream to investigate were very likely to encounter an accident, and the situation at that time must have been so tragic that the bamboo raft they were riding on was so seriously damaged.

And if so.

It is very likely that all six soldiers have been killed...

Just when I was thinking about it.

A larger drifting object gradually appeared in their sight. It was half of the remaining bamboo raft, and the originally neatly arranged bamboo poles had been completely misaligned and were barely held together by hemp ropes. To provide you with the fastest
