Because of Xiang Nan's caution, the three of them did not go astray.

Hence, Xiang Nan and the others were able to avoid the extremely terrifying dangers such as corpses, water wasps, sword-toothed vipers, and blue-scaled pythons in the cave.

 After walking in the cave for half an hour, I finally came out safely.

Before leaving the cave, the three of them closed their eyes. After a while, they opened their eyes and saw a very dense subtropical primitive jungle in front of them.

Recklessness, vines, dense and strange flowers, countless flowers, countless, a deserted scene, it is estimated that no one has set foot in here for thousands of years.

After the stream entered the jungle, the water slowed down. The three people docked the bamboo rafts on the shore, tied them to the trees on the shore with ropes, and then unloaded all the equipment.

“Brother, where are we going?” the old foreigner asked.

“Go north.” Xiang Nan took out his compass and looked at it, then pointed to the north road.

Although he has not personally seen the map of King Xian's tomb in Chen Yulou's hand, based on the information provided on TV and books, it was concluded that King Xian's tomb is indeed located in the north of Insect Valley.

 The old foreigner nodded, and then walked north with Xiang Nan and Hua Ling.

 …

In the Insect Valley, the air is humid, the climate is hot and humid, and the temperature remains at about 25 to 30 degrees all year round. In addition, it is surrounded by mountains and is airtight. Therefore, the plants in the valley have almost no natural enemies and can naturally grow wildly. .

Hence, it is really difficult to walk through this jungle. Because the vines grew so densely that they could hardly stand, Xiang Nan had to take out his machete and cut a way out.

There are also many snakes, insects, rats, and ants in the forest, especially mosquitoes, which are as big as dragonflies outside. After being bitten by it, the swelling would probably be as big as a steamed bun.

 Fortunately, Xiang Nan knew that there were many poisonous insects in the Insect Valley, so he prepared sachets in advance, which had a certain repellent effect. Moreover, the three of them were still wearing long shirts and long trousers in this hot and humid environment of more than 30 degrees, and even wore bee-proof hats on their heads. Therefore, although they were sweating from the heat, they were not bitten by poisonous insects.

 After a lot of hard work, the three of them finally came to two banyan trees.

 I saw that these two banyan trees were quite spectacular. The tree body is as thick as a stone pillar, and the crown hangs low, as heavy as a cover. The two thick tree bodies grow like twists and twists together four or five times, forming a rare couple tree.

There are also many unnamed huge flowers and parasitic plants growing on the tree, like a large colorful flower basket in the forest.

 It was already noon, Xiang Nan suggested to take a rest, drink some water and eat some food.

 The old foreigners and Hua Ling were all eager for this, and immediately agreed.

Xiang Nan took some water from a nearby stream, filtered it a little, then used his internal energy to boil the water, and then brewed three bowls of salty mocha, which could replenish calories and salt. Each person ate another compressed biscuit, which was enough to fill their stomachs.

“Give me your hands,” Xiang Nan said again.

 Old foreigner and Hua Ling handed their hands to Xiang Nan.

Xiang Nan immediately performed his exercises, and the true energy circulated rapidly in the three people's bodies, allowing them to quickly recover their physical strength. Moreover, the soaked clothes of Hua Ling and the old foreigner were quickly dried under the influence of internal energy, evaporating a large amount of water vapor.

 “Senior brother, you are so amazing.” Hua Ling couldn’t help but admire.

Although she can also use her internal power to steam dry clothes, she will never be able to do it as easily as Xiang Nan.

 …

After taking a short rest, the old foreigner stood up and said, "Brother, let's set off." "Don't be in a hurry, there is something here." Xiang Nan waved his hand and immediately jumped up to the top of the banyan tree.

Sure enough, we saw a section of the cabin of a huge airplane inserted upside down between two trees. The wings and tail were missing. There were several large holes in the fuselage. The holes were filled with things, making it impossible to see what was going on inside.

The hatch has separated from the fuselage and was completely deformed by the impact. There are rust spots everywhere, and it is covered with thick moss and vines. It has almost grown into the trunk of the tree, and the landing gear is stuck in the gaps between the trees.

 “Come up~” Xiang Nan shouted to the old foreigner and Hua Ling below.

When the two of them saw this, they quickly used Qinggong and flew up.

When they saw that there was half a plane on the tree, both of them couldn't help but be startled, "Brother, what's going on? Why is there an airplane here?"

“This was a plane that the United States used to transport military supplies from India to China. It crashed here for some reason.” Xiang Nan explained.

During World War II, in order to support China’s resistance against Japan, the US military opened a hump route and used transport aircraft to transport arms and supplies from India to the country.

The Hump Route is 500 miles long, with snow-capped mountains above 4,000 meters above sea level along the way, making it extremely difficult to fly over. From 1942 to 1945, a total of six to seven hundred planes crashed.

One of them happened to fall in the Insect Valley, which happened to correspond to the sign of "collapse of the sky" mentioned by King Xian.

“Brother, you are so awesome. How did you know there was a plane here?” Hua Ling asked in surprise.

"Of course we can figure it out." Xiang Nan waved his hand, "Okay, don't talk anymore, there should be what we need in this plane."

As he spoke, he lifted the vines covering the fuselage and walked into the cabin. Sure enough, there were more than a dozen wooden boxes in the cabin. When they were opened, they turned out to be Thompson submachine guns, also called "Chicago typewriters."

These guns and the bullets underneath were in good condition, so Xiang Nan asked Hua Ling and the old foreigner to each bring one with the bullets fully loaded.

 In the Bug Valley, there are many strange beasts, such as the Eagle Owl, the Piggy Baby, the Huo's Undead Worm, the Rouzhi Taisui, and so on. Having these three guns can make a big difference.

 …

In addition to practicing martial arts, Hua Ling and Lao Yangren also received training in diving, shooting, mountain climbing, and skiing. Naturally, they were no strangers to Thompson submachine guns. Each of them took one and filled it with bullets.

After they finished taking it, they left the banyan tree canopy and returned to the ground.

“Stay out of the way.” Xiang Nan said, then took a deep breath and clapped his hands violently at the two banyan trees.

 The palm power surged out like an angry wave, like a twelve-level wind blowing up from the plains. The two big trees were shaken violently by this huge force, and then there was a loud creaking sound, and then the two big banyan trees actually split from the middle.

Hua Ling and the old foreigner were all shocked. They didn't expect that their senior brother's martial arts skills were so high. Such a big tree collapsed with just one palm strike. It's really unimaginable, extremely powerful.

 “Senior brother, you are so awesome!” Both of them exclaimed stupidly.

"There are too many vines hanging on these two big trees, and they are already overloaded. I'm just pushing the boat along." Xiang Nan waved his hand.

Although with his strength, there is no problem in knocking off these two big trees. But the credit this time is indeed not his. There are too many vines on these two big trees, and they are absorbing the nutrients from the trees, causing the trees to be overwhelmed. Coupled with Xiang Nan's palm power, he was able to make it split from the middle.

“Brother, what is that?” Hua Ling suddenly pointed at the crack between the two trees and said.
