More than twenty rattan ropes were neatly placed beside Tang Chen.

It was the result of three days of hard work.

The length of each of the completed rattan ropes was about fifteen meters, which was about half longer than the ten-meter interval required for the temporary footing point, and Tang Chen left enough room for binding loss and spacing error.

There is also a pile of vines waiting to be disposed of next to it, and in two days, this batch of vines will all turn into vine ropes.

Tang Chen narrowed his eyes, estimating in his heart how long it would take to finish processing this batch of vines. The time spent, combined with the number of rattan roots that can be obtained in the end, gives a rough estimate of how long it will take to get enough rattan.

In five days, the rattan rope obtained is enough for the 150-meter ladder. If the cliff height is no more than one thousand meters, Tang Chen is expected to use more than 30 days to get a long enough rattan rope.

This does not mean that the Ladder Project is about to be successful, and knotting is only one part of the plan, and it is probably the easiest part. Setting up temporary foothold and advance base is the most important thing, the degree of difficulty and danger are far beyond knotting, especially for middle and high-level operations, the time required is incalculable, but Tang Chen is still sincerely happy.

These rattan ropes represent the hope of getting out of trouble, and they are the reward of his unremitting efforts!

With little Tom by his side, Tang Chen didn't need to worry about the threat of the black beetle, even in the middle of the night, he didn't stop to rest. When he is exhausted, he meditates cross-legged and continues to work after regaining his energy. Tang Chen was exhausted, but his eyes were full of hope and longing.

As night falls, a bonfire rises in the middle of the valley.

During the announcement, the boy sat in front of the campfire and weaved rattan ropes until he fell asleep.

At the same time, the "rustle" sound sounded again.

When Tang Chen opened his eyes, the kitten had already crawled up, energetic and murderous.

Soon, hundreds of black beetles became the souls under its claws again, enough for it and Tang Chen to eat beautifully for a day. The cat flicked those beetles together, and returned to Tang Chen with brisk steps, its tail raised high, meowing non-stop, and its body rubbing against Tang Chen's legs. After getting along for a long time, and being helped by food to deepen the relationship, little Tom became more and more dependent on Tang Chen, looking forward to receiving Tang Chen's praise like a child.

Tang Chen couldn't help but laugh a little.

patted its little head: "Good job, I'll make you something to eat tomorrow!"

The cat was satisfied, barked again, and staggered back into Tang Chen's arms to continue to sleep.

The kitten Mingjin withdrew his troops, and the remaining black beetles within five meters slowly retreated to the rear, and only changed their routes after running away. The fierce and peerless black beetle only had the share to be slaughtered in front of Little Tom, and Tang Chen couldn't help but sigh with emotion.

Tang Chen has been observing the movements of the black beetle in the past few days.

The black beetle lies dormant under the rotting leaves during the day, and when it comes out, it climbs to the eastern cliff. At the bottom of the cliff to the east are small holes hidden under the vegetation, about the size of an adult's fist, and the black beetle crawls into the small holes and disappears, only to reappear around the clock and return to the ground. The cave was very deep, and the cliff at the foot of the mountain did not know what material it was, and the hardness was amazing, which made Tang Chen desperate to find out.

There should be food in the cliff wall that black beetles like.

It's not hard to judge.

If there were no Tom in the valley, the black beetle would be at the top of the food chain. They don't eat rotting leaves and rotten wood, and except for little Tom, all the other animals in the valley have long been wiped out by them, and even the small insects have not been spared. The black beetle population is large and will not be without a food source.

The black beetle is very aggressive, and they also show a certain amount of intelligence, such as when attacking, they will surround in a roundabout way, Tang Chen believes that the rank of the black beetle will not be too low. At first, he conservatively estimated that the black beetle might be a second-grade spirit animal, but later he couldn't even peel off the shell of the dead black beetle, and began to realize that the judgment might be a little conservative, and the large amount of spiritual power contained in the black beetle's flesh also confirmed this from the side.

The black beetle is likely to be as high as three pins!

The spiritual food made of the three-grade spirit beast, I'm afraid the head can't enjoy it often, brother eats and plays!

Tang Chen was in a good mood and his appetite increased greatly.

Feeding on black beetles every day, Tang Chen's spiritual power improved significantly.

In order to avoid wasting spiritual power, Tang Chen had to meditate after each meal, refining the abundant spiritual power in the food as much as possible for his own use. Trapped in a Jedi, every time he improved his strength, his chances of getting out of the valley were one point greater, and Tang Chen had never been so eager to improve his cultivation as he was now.

The biggest problem now was that Tang Chen's fifth-level Qi refining cultivation was too low, and the refining efficiency was low.

Climbing, cutting vines, and follow-up processing mainly consumed Tang Chen's physical strength rather than spiritual power, which also made Tang Chen's spiritual power in his body always in a state of overflow in the past few days. The excess aura that cannot be absorbed gradually escapes from the body through the pores of the whole body and returns to heaven and earth.

Even if he had never liked cultivation, Tang Chen knew how undeserved it was to let spiritual power go to waste.

Wasting food is the greatest original sin, and it is also true to exchange food for spiritual power.

Gotta find a way to make a change!

Holding the rattan rope, Tang Chen fell into deep thought.

After a long time, he picked up a truncated old vine from the ground.

A small fireball flew out, attached to the old vine and burned silently. At the fracture of the vine, the remaining moisture in the vine is forced out and sizzles. There was not much spiritual power in the fireball, not enough to ignite the entire old vine, and when the flame was extinguished, a scorched black mark was left on the old vine.

He took out a knife and cut it hard at the mark, and after a while, the old vine was divided into two sections.

Tang Chen nodded with satisfaction, burning for a while and then cutting it can indeed save some effort.

Some links can indeed reduce physical exertion with more spiritual power.

Taking cutting vines as an example, those mountain vines with gourds are extremely tough, and they caused a lot of trouble to Tang Chen a few days ago, and more than ten knives may not be able to successfully cut one. Instead, use a small fireball to greet him, no need to burn it, just need the high temperature of the small fireball to dry the mountain vines, just like what he did just now, it is much easier to cut; and climbing, if you apply the appropriate wind spell when climbing, the speed will increase slightly, he is very sure of this skill, he has used it before, and there is no need to try it at all.

For the time being, I didn't think of a way to use spiritual power.

He rejoices with the improvements in climbing and mowing, which will improve work efficiency.

Improving efficiency is only one direction of the use of spiritual power.

Another important point is to enhance the security of the Ladder program.

Tang Chen paid great attention to the problem of the reliability of the rattan rope after it was dried, and he originally planned to dig a small pond to soak the rattan rope to keep the rattan rope as hydrated as possible. But after thinking about it, he will eventually tie the rattan rope to the cliff in order to do all kinds of preparations on the cliff, considering the height of the cliff and the time it takes to bind the rattan rope in the middle and late stages, this process may be relatively long, taking months or even longer to complete. It is difficult to keep the moisture of the rattan rope for such a long time, and soaking in the pond is not enough to ensure its reliability.

If this problem is not solved, there will be no security at all for the ladder that carries the hope of getting out of trouble.

Forcibly get on the horse, and in the end, the ladder will probably not lead to the outside, but to the Yellow Spring!

If there are flying and climbing magic weapons......

Tang Chen thought of refining weapons, and the magic weapons were all refined.

If you don't have a magic weapon, you can't refine it yourself?

In addition to cooking, all he can do is refine the utensils.
