"Why?" Hu Kai asked.

"Because, I don't know what kind of human amber is?" Xiao Xie said, "If you count the human body inside, its proportion has far exceeded that of fresh water, and it can't float at all!" ”

"I'll see!"

As soon as Xiao Xie's words fell, Yang Lele suddenly picked up a piece of amber fragment on the ground, raised his hand and threw it into the hot water under the steps.

But when he saw the fragment gurgling, he immediately sank into the water and disappeared without a trace.

"Sure enough!" Xiao Xie shrugged his shoulders helplessly and said, "It seems that it really can't float!" ”

Hearing Xiao Xie's conclusion, everyone's newly ignited hope was instantly extinguished again.

"Wait a minute!" Who knows, seeing everything in front of him, Hu Kai's eyes suddenly lit up, and he said excitedly, "Xiao Xie, although your idea doesn't work, it reminds me!" Actually, we don't have to, we have to let that amber float, huh? ”

“What？ What do you mean? The crowd was puzzled.

"Here, it's just a pool!" Hu Kai said, "It's not a lake!" Its depth is limited! ”

"I don't understand!" Tingting still shook her head.

"It's like a game we used to play when we were kids!" Hu Kai said, "We just need to put these human amber pads in the water and use them as a bridge, can't we step on them and cross them?" ”

"Right?" Tingting finally understood, and gave a thumbs up to Hu Kai.

"Huh?" Xiao Xie said with understanding, "Maybe it's okay!" The quality of these human amber is not high, and theoretically, we can move it! More than 20 pieces, all spread into the water, can build a bridge! ”

"Hmph, it's theoretical!" Tingting pouted, "This is called practice is greater than theory!" Let's go, let's lift it up and try it first! ”

So, Hu Kai immediately arranged for Miss Pearl and Zhang Shi to guard the gate, and then led the others to carry those huge human amber.

At first, Hu Kai thought that they would have to use auxiliary tools such as crowbars or ropes, but he didn't expect that each person could easily lift a huge piece of human amber by holding a corner.

"Let's go!"

With Hu Kai's order, they worked together, stepping on many treasures and dead corpses, and headed towards the back of the palace.

When they reached the water's edge, they gently lowered the amber into the water, and the amber stood firmly in the water like a foundation.

It turns out that although the water here is extremely hot, the depth is not even half a meter, and in some places it can only reach a person's knees.

Amber is placed inside, which is both strong and stable.

Immediately afterwards, Hu Kai and others brought a second piece of human amber nearby, stood the second piece behind the first piece, and pushed it hard, and the two pieces of amber extended towards the depths of the pool like building blocks.

“Yes！” Xiao Xie clenched his fists, feeling that this plan was very feasible.

Seeing hope, everyone naturally worked harder, but in half an hour, a bridge made of human amber was built.

The bridge is slightly skewed due to the amber in the distance being difficult to orient, but in general, with some care, they can basically get through.

In addition, there is one more point in their favor. Due to the steaming water in the pool, the Nazi soldiers who came from the front could not see it at all.

If they retreat later, they will not attract the attention of the enemy, and they can be described as silent.

Bang, just in case, everyone put up another piece of human amber and pushed it up to the bridge again. The specific gravity of these ambers is just right, and it is neither floating on the surface of the water nor sinking in the water and unable to move.

After the joint efforts of everyone, this human amber bridge is completely completed. All that's left is to start a silent retreat!

At this time, the Nazi soldiers around the periphery were also a little out of breath! They picked up a lot of debris from the passageway, and actually built a bunker from the platform.

At this moment, many Nazi soldiers were lying behind their bunkers, constantly watching this side of the palace, and as long as there was any movement, they would definitely take action.

It seems that these Nazi soldiers also grasped the weakness of Hu Kai and others. They felt that the palace was steaming hot, and these people couldn't last long at all. Within an hour, they would have taken the initiative to come out and surrender.

However, more than an hour has passed now! But in the other party's palace, there was still no movement. This time, they were a little out of breath.

They couldn't see the situation on the other side of the palace, so they were also deeply suspicious that the other party would have found another way out and run away a long time ago?

Thinking of this, they decided again to send two daring soldiers to investigate.

The two daring soldiers, fearless, put on their weapons on the spot, and began to jump along the stone platform of the flower bed, in the direction of the palace.

Who knows, the two of them had just jumped a few steps, only to hear a whoosh, a feather arrow shot into the air, straight towards the leading soldier.

The soldier screamed, tilted, and fell into the boiling water. The other was so frightened that he turned around and ran, jumping back to shore as fast as he could.

Syllable...... Syllable......

The Nazis, who had been waiting in the bunker for a long time, opened fire together, only to knock the stone pillars of the palace in all directions, and the debris flew everywhere. But in the midst of the bullets, Miss Pearl was long gone.

It turned out that after shooting this arrow, Miss Pearl had already turned around and ran to the other side of the main hall, and began to climb onto the human amber with Hu Kai and the others and cross the river.

The Nazi soldier who fell into the water was scalded and wailed, and finally with the help of others, he managed to climb ashore with difficulty.

Seeing that this person was burned all over his body, and the misery was unbearable, the other soldiers were all afraid, and they no longer dared to attack the main hall.

However, they felt that since the other party had suddenly fired cold arrows at them, it meant that the enemy had not found another way out, but was indeed trapped inside.

In this way, they are more at ease. After the ceasefire, they rearranged their defenses and began to wait patiently.

However, what they didn't know was that at this moment, Hu Kai and the others had already climbed onto the stone bridge made of human amber and began to quietly evacuate the palace.

The bridge was paved without any problems, and after everyone went up, they began to climb cautiously to the opposite bank.

However, something unexpected happened!

No one could have imagined that the melting point of these human amber was so low that after being boiled in boiling water for a while, they began to slowly melt!

Especially the first few pieces that were thrown into the pool, the bottom of them has melted a lot at the moment, and they are about to be swallowed up by boiling water!

"Oh!" Tingting turned her head and shouted at Xiao Xie, "Engineer, how did you calculate?" Why did it melt back? ”

"It's none of my business! I've said it all, the material is unknown! Xiao Xie explained, "The melting point of rosin is more than 170 degrees!" How do I know ......"

"Okay," Hu Kai quickly stopped him and said, "Don't hold him accountable now!" I think everyone should keep their mouths shut and hurry up! (To be continued.) )
