These "gum trees", while the two of them were chatting for a few words, the micro-coke, which was originally only a layer on the surface, was gradually fading to burn black, and new mucus was constantly oozing from the gel-like fibers, allowing those hard shells to slowly soften, decompose, and be swallowed. The "Gum-Tree Forest" that stands tall and tall in the sky has also begun to crumble one after another, about to collapse and recondense, and to combine back to the original 3D maze that is entangled with each other.

The texture of the hardened climbing material that Shu Kang was familiar with was changing drastically, and there was still half way to the exit at the top. This forced Shu Kang to climb faster.

The core muscles near the spine are all tightened, inhale, hold your breath, advance with your left hand and right foot, and forward with your right hand and left foot.

The book rose rapidly, and soon Hai Xiaolou fell out of four or five positions, and without knowing it, he was still rushing upward.

Hai Xiaolou was very unconvinced, he had grown so big, and no one had ever walked faster than him in this maze, not to mention, this was still a girl who surpassed him, which greatly stimulated his self-esteem, so, regardless of everything, he also began to try to keep up with the speed of the book.

However, his weight was great, and if he was on solid land, more than brute force, then Shukang would certainly not be his opponent; But now it is climbing on a giant tree of the Gel Forest, which is heavy in size and strength, but it has become a disadvantage. Only by skillfully using the elasticity and toughness of this material, with just the right amount of force, can the speed of the rise be faster.

Therefore, the harder you work, the more you fail, that is, Hai Xiaolou at this time deeply understands what it means to "want to be fast, you can't reach it", so she had to sigh, slow down, and readjust her breathing and movements, which can be regarded as gradually approaching the agile and elegant figure of Shukang.

Both of them work hard, but sometimes, it is not necessarily possible if you work hard, and the decisive role of the environment should not be underestimated.

Just when the distance between the two of them was one and a half positions away, and Shu Kang was only three and a half positions away from Kong Ding, the last thing they wanted happened.

A large patch of red struck, and the tip of the tallest "gum tree" was cut off at once!

With a foul-smelling gas spraying over, the remaining branches were blown by this huge air current, and began to sway sharply, and both of them used their limbs to hug the "branch" in front of them, and began to find balance with this foul smell, in a swing of nearly 90 degrees.

Now the problem is that the most troublesome "chemical attack" has finally arrived!

The stench was about to replace all the air here with methane, and although Shu Kang had tried to hold his breath as much as possible, he still inhaled it irrepressibly, and it was simply smelly and headache-prohibitive.

"Calm down! The action must not be deformed, it must be steady. ”

In the ears of the book, it seemed that the words of grandma as she taught her to play basketball, dribble, and prepare for a new attack sounded again.

"Methane is a slightly toxic class and is basically non-toxic to humans, but when the concentration is too high, the oxygen content in the air is significantly reduced, making people suffocate. When the methane in the air reaches 25%-30%, it can cause headache, dizziness, fatigue, difficulty concentrating, rapid breathing and heartbeat, and ataxia. If it is not separated in time, it can lead to suffocation and death. Liquefaction of this product in skin contact can cause frostbite. Allows the gas to safely diffuse into the atmosphere or be used as a fuel. It has a simple asphyxia effect, and at high concentrations, it causes poisoning due to hypoxic asphyxia. In the air, 25~30% of them will experience dizziness, accelerated breathing, and movement disorders. ”

Her mother, who teaches chemistry, has long been introduced to this slightly toxic gas when she visited the "biogas digester" in the countryside, so judging from the current body reaction, its concentration has now reached more than 25%. Fortunately, this is only the content brought by the evil breath ejected from this red ball, and it should not be the case in the sea Xiaolou below.

Shu Kang's intuition is that he should give the source of this gas, a big pocket, to block this smell, and make a fuel bag to see if it will be used later.

What do you use to blow out a big pocket?

By the way, isn't it the best material right in front of you? Shu Kang picked up a small piece of gel in his hand, leaned it up, blew it, and sure enough, a small balloon bulged out.

"Alas! It's really 'stepping on iron shoes and finding nowhere to go, and it takes no effort to get it.' Just use it. ”

Shu Kang immediately took out the wooden hairpin, drew a powerful compressed air cylinder, and then while shaking, he inserted the inflatable port into the trunk of the rubber tree in front of him, pressed the inflatable button, and saw that a huge balloon soon appeared in front of him.

The balloon rose bigger and bigger, and finally burst after meeting the red, and then stuck to the red, and the source of the smell attached to the red, methane gas, also ejected in the opposite direction after the chaotic red, and blew out a large balloon in the opposite direction ——— a balloon filled with pure methane gas.

Enveloped in this self-inflicted cloud of methane gas, the red mass moved with the ball again, and ran away in a rage.

"It's a pity! I haven't had time yet, shoot a rocket at it! ”

Shu Kang originally planned that at this time, adding another fire, the "sea leaf lizard" who always wanted to trouble her would be hit by her arrow and burned to death.

"Humph! I'll let you go this time, count you as acquaintances, and run fast. The book nagged at the sea leaf lizard, who had been scared away by her again.

The gum tree was still shaking and sliding, and the distance from the top of the hole had stretched to 7 or 8 positions.

Shu Kang looked at Hai Xiaolou, who was two bodies away from his feet, and asked loudly, "Are you okay?" ”

"Be careful! Look at the head! ”

Hai Xiaolou suddenly made a louder voice than her and shouted loudly.

When Shu turned around, she saw that the branch she was on suddenly seemed to melt, and the whole section became soft and flowed down to the top of her head!

"Ahh Before she could finish screaming, Shu Kang's long ponytail had been completely covered by this melt glue, Shu Kang raised his hands up, desperately protecting his face, only to see that the speed of the sol was accelerating, and the whole helped her fix her last protective head, trying to pull out the hair style, she struggled hard, but saw that this glue had wrapped her whole body, only a breathing hole that she desperately set aside, and tenaciously kept a hollow, not being glued to the closure by the thick glue.

Shu Kang now understands a little, when she was a child, when she took the glue used for study, soaked a small seven-star ladybug caught from the garden, and wanted to make "amber", the poor little worm's mood ——— her, and now she will soon become a "human amber" sample.
