In the first three days, Wan Lin led his team members to march continuously, and at night he relied on digging wild vegetables and using tree vines to trap small animals to satisfy his hunger.

In the past three days, Wan Lin passed on his experience of living in the mountains one by one to the team members, teaching them to identify edible weeds, mountain fruits, fungi, and herbs that can stop bleeding, treat stomach troubles, clear heat and detoxify in critical moments.

Three days later, Wan Lin took the team to the depths of the mountain and stopped. The team members wiped the sweat from their faces and looked around at their surroundings.

In front of you is a large canyon, the wall of the gorge is about a thousand meters high, straight up and down like an axe and chisel, and several streams flow down like white ribbon from the peak. The valley is overgrown with weeds and surrounded by trees, and there is no eye to see the edge. Raising his eyes and staring, the whole peak shape is like a long winding dragon lying on the cliff, and a towering dragon head in the distance seems to be turning its head viciously to look around the deep valley.

"What a steep valley!" Lingling looked intently at the deep valley and muttered. All the team members stared intently at the valley, and all of them had grim expressions on their faces. Obviously, that's the environment they're dealing with.

Wan Lin glanced at the team members and said slowly: "This canyon is 120 kilometers long and more than 60 kilometers wide, and the peak is like a long dragon lying horizontally, so it is called Wolong Bee by the locals." And the precipitous valley below naturally became Wolong Valley. The valley is overgrown with weeds, strange trees, poisonous insects and beasts are everywhere. Known locally as Death Valley, it's rarely accessed. I ask you to cross the canyon in seven days, and I am waiting for you at the end of the canyon".

He turned his head to look at the precipitous valley and continued, "I have taught you the knowledge of self-survival in the wilderness outside of books a few days ago, which is far more simple and practical than what you have in textbooks. Every grass, tree, flower and vine around you may be your savior in times of crisis! In the event of a critical situation, weapons and flares can be used to call for help. However, you must remember that you only have three bullets, do not use them unless it is urgent, it is strictly forbidden to use communication equipment at the beginning of the operation, and it is strictly forbidden for each group to help each other during the operation! Now let's start grouping".

After Wan Lin finished speaking, he immediately divided the team into four groups. Xiaoya and Lingling in a group; two groups of vigorously and Chengru; Hong Tao and Wei Chao three groups; Qidong and Wang Hong four groups.

Wan Lin deliberately divided Xiaoya and Lingling into a group when considering grouping, mainly because the two of them had only been in the assault team for a short time, especially because they lacked survival experience in the wild. And one of these two people is a military doctor, and the other is an expert in communications and electronic countermeasures, and they are indispensable technical personnel for the commando, so they must make up for their shortcomings.

The other team members saw Wan Lin put the two female team members in a separate group, and they all looked at Wan Lin worriedly. Wan Lin didn't explain, looked down at his watch, and shouted: "A group, stand upright, go!" ”

An hour later, Wan Lin shouted again: "Two groups go!" ”……

Every hour, Wan Lin sends out a group, in order to widen the distance between the groups and prevent crossover on the way, so as to achieve the purpose of individual training.

The four groups all set off, Wan Lin looked at the cliff on the side in front of him, and shouted at Xiaohua, "Go!" He turned and ran towards the cliff. He had to climb the cliff and chase the first group of Xiao Ya and the others who entered first, and in such a treacherous deep valley, he couldn't let the two female team members be in danger.

At this time, Xiao Ya and Lingling had already gone deep into the deep valley with Xiao Bai, and Xiao Bai had already gone into the deep weeds and jumped to the front to explore the way. Xiao Ya and the two of them held a saber in one hand and a military shovel in the other, constantly chopping the vines in front of them, and the soles of their feet were weeds more than half a person deep. The two of them were already sweating profusely and their faces were covered with sweat.

Lingling waved a shovel and muttered, "Stinky Wanlin, I don't know what my surname is when I become an official?" Why should we put Cheng Ru, a stinky boy, in our group, this kind of strength should have been done by their stinky boy", as soon as the words fell, I listened to her, "Ah! With an exclamation, he threw away his shovel and retreated several steps, looking ahead in horror.

Xiao Ya heard the scream, and with a "hula" sound, she pulled the automatic rifle on her chest and loaded it, and the muzzle of the gun was immediately aimed at the front.

A gray-brown long snake curled up more than a meter long hanging upside down on the tree vine, shaking its triangular head, two soybean-sized eyes stared at the two of them with a lifeless cold light, and two blue-white fangs were exposed in the open mouth, and a red core was rapidly expanding and contracting in the mouth, making a "hissing" sound.

"Five-step snake!" Xiaoya gasped. This is a highly venomous snake, it is said that after being bitten, it will fall to the ground after not taking five steps, so it is commonly known as the "five-step snake".

At this time, Xiao Bai had already jumped back with Lingling's scream, and it jumped on a branch more than three meters away from the poisonous snake, staring at the poisonous snake with red eyes.

The eyes of the poisonous snake have shifted to Xiao Bai, and the originally cold eyes suddenly showed a cringing look, and the snake body that was raised against Xiao Ya just now was already slowly retreating.

Seeing that the viper's attention had been attracted by Xiao Bai, Xiao Ya slowly put on the automatic rifle on her back, pulled out the military shovel behind her, suddenly took a step forward, and slashed at the snake's head with a shovel.

Feeling the sound of the wind, the snake head of the five-step snake suddenly shrank back, and suddenly turned the snake's head to face Xiao Ya, the snake body swung on the branch, and the curled snake body rushed towards Xiao Ya like an arrow off the string.

"Hmmm" A white light flashed from the side, bringing the snake body that pounced on Xiaoya two or three meters away. Xiao Ya and Lingling, who were shocked into a cold sweat, looked at each other, and Xiao Bai had already pounced and cut the snake's waist in two.

Lingling, who was pale, wiped the cold sweat from her face, took a step forward, raised her leg and kicked the front half of the snake body with the snake head.

"Whew!" With Xiao Bai's exclamation, Xiao Bai, who was squatting in the middle of the broken snake, suddenly stretched out his right paw and slapped it on the snake's head.

It turned out that the poisonous snake that had been bitten off and had closed its mouth was just as Lingling was about to kick it, and suddenly opened its terrifying mouth, and two fangs dripping with turquoise venom were facing Lingling's flying feet.

"Oh my god!" Lingling was so frightened that she sat down in the grass. She didn't expect that the poisonous snake that had been cut off by Xiaobai still had the ability to attack.

"Smack", before the frightened Lingling could come to her senses, Xiaoya suddenly swung a shovel and slapped Lingling's thigh.

"Oops" Lingling shouted, just about to get angry at Xiaoya, Xiaoya was already smiling and raising the shovel, a big scorpion the length of a thumb was completely printed on Lingling's pants like a photo, and the tail with a scorpion needle was raised high.

"Mom!" Lingling screamed and jumped up, reaching out to remove the scorpion from her pants. Xiao Ya hurriedly reached out to stop her, tugging at her pants with one hand, and holding a military dagger with the other hand to carefully scrape off the scorpion on it.

"It's terrifying, what kind of place is this!" Lingling said with tears in her eyes and a choked voice.

Xiaoya hurriedly hugged Lingling: "Don't be afraid, we still have Xiaobai, we will be safe with it", her eyes looked at the gradually dimming valley in front of her, and there was a look of fear in her eyes.
