And as a reward for that mission, a piece of treasure jade made by the hexagram elder himself was handed over to Lin Jiu's patriarch.

This level of jade, there is no piece in the family every ten years, so you can imagine its preciousness.

This kind of jade is called ghost jade, because this name is not auspicious, all of them are also called decay jade, which has extremely powerful protective effects.

The person who wears the jade is known as the inviolability of all evils, although there is an exaggeration, but it is by no means an exaggeration.

If you have a decanate jade amulet, it is basically equivalent to a clansman who has an earth eye, and ordinary spirits can't get close to it at all, and this alone has already explained the value of decanate jade.

After Lin Jiu heard about the origin of the jade, he bragged fiercely to Lin Congfeng, and repeated it a few times from time to time.

Therefore, for the value of this piece of jade, Lin Congfeng is very clear.

From the time he knew Lin Jiu to now, he had never seen Lin Jiu take off this piece of jade, even if he took a bath, he wore it on his body.

And now, for the first time, Lin Jiu took off the jade and handed it to Lin Congfeng, and the shock in Lin Congfeng's heart can be imagined.

However, he is not a hypocritical child, and he doesn't want to stage any crying scenes, so Lin Congfeng sighed and took the jade and put it on his body.

If you want to go down, you first need to verify the air quality in the well, which is a necessary prerequisite.

However, it is a step that ordinary people are very likely to ignore, and for the Lin family, these rules that have been emphasized countless times are impossible to forget, because forgetting means death.

Lin Congfeng took out a fire fold, blew out the flames, and threw it far into the well.

First of all, there was no explosion, and it was determined that there was no combustible gas such as biogas at the bottom of the well, and even if there was, the amount was below the safety line.

After a while, Lin Congfeng walked over to look at the bottom of the well and found a little orange fire.

Fortunately, there is no suffocation in the well.

After confirming these two points, this well can be considered to be able to go down, otherwise no matter how anxious Lin Congfeng is, there is no way.

It's not that there is no oxygen supply equipment in the family, but it is definitely not something that children can get, even if they have money, it is impossible to trade that kind of special equipment.

Once the air quality is determined, the rest is a matter of the rope.

The rope they carry is more than 30 meters, it is a special rope produced by the family, it is extremely thin and light, but there is no problem in bearing the weight of an adult.

According to Lin Congfeng's last estimate of the bottom of the well, this well should be regarded as a shallow well, and it will not exceed fifteen meters at most.

This is a relatively normal depth, under normal circumstances, ordinary homes simply cannot afford to drill a deep well, a depth of 100 meters is more difficult even with professional equipment, and the cost is too high, simply not compatible.

Lin Jiu found a wooden pillar, pushed it, it was very strong, he tied the rope well, and handed the other end to Lin Congfeng.

Lin Congfeng put on black gloves, and then skillfully tied the rope into a complex knot on his body.

All children need to master the various knotting methods of rope before the age of five, which is the most basic skill that every Lin family member needs to learn.

Abseiling is a compulsory course, and it is actually quite risky to do abseiling with a single rope, but now it is in the well and not on the cliff, and the situation is not bad.
