Izaku applies a similar nature to the assimilate all creation technique and begins to focus on his earth chakra while gathering the details of the minerals in the ground. He then continues by merging his body into the ground by matching it's compounds using the manipulation of earth chakra. However all of this is a very hard process, thus making it slow for Izaku to accomplish. After doing so, he traveled a few meters forward and emerged once again in a slow manner.Unlike the hiding like a mole technique this one allows you to actually merge with the earth and stealthily move throughout it without disturbing it. However, the major drawback of this technique is that it's slower and you cannot travel to greater depths thus you're left extremely vulnerable to earth techniques.Rank: C

Description: Using this jutsu, a person can hide underground until they're ready to attack an opponent by merging with the ground itself. By utilizing earth-chakra, the person can stealthily emerge from the ground without disrupting the ground around him. The disadvantage with this technique is that merging with the ground is rather slow and while perfomring the technique, the user is vulnerable to high ranked Earth techniques. The user isn't hidden from doujutsu or sensory ninjas and cannot travel beyond the 3 meter deep mark. Moving around in the ground is slow and the user cannot sense very well what is happening above.
Perform the hand seals [Rabbit → Boar → Rat → Horse → Tiger → Snake] and slam your hands down onto the ground. Flow concentrated chakra into the dragon veins flowing underground and rise up a single section of earth in the desired location and after rising it split it down the middle, creating a chasm. As your skill in earth release increases you will be able to perform this technique on a higher level.

Description: The user will first perform the required hand seals Rabbit → Boar → Rat → Horse → Tiger → Snake and slamming the hands on the ground, the user can, by flowing concentrated chakra into the Dragon Veins flowing underground, tear the earth apart, creating large chasms by raising the earth in two oposite sides in the desired location and then splitting that piece of earth through the center. The length, width, direction, and curve of the chasm are all up to the user. Manipulating the Dragon Veins requires fine chakra control, but if one has such skill, they can use this technique to divide the space between the enemy and their own team in two, destroy enemy camps or defences, and even to attack.
Note: This does not split the earth appart directly to cause opponents to fall in the fissure.
Unlike hiding like a mole, this technique doesn't allow you to really sense what is happening above ground and also restricts you to only being able to travel three meters in depth. Also, it is slow on the sinking part, however the good thing is that it doesn't disrupt the earth at all. Also, I am not sure if I would be able to use lower ranking earth ninjutsu like hiding like a mole. As for actual uses, I would do the same as I did with hiding like a mole although more stealthy due to the lower speed of both sinking and traveling.
After slowly practicing the long sequence of hand seals, Izaku weaves them together in a quick fashion as he then slams both of his hands on the ground and infuses it with his earth chakra. He causes a 2x2 meter block of earth to rise up above him, which is quickly split down the middle.
I don't entirely know what the dragon veins are. As for the technique itself, although it requires a lot of hand seals, it seems like a more advanced version of the variant method of the 90 degree wall technique I previously learned to split something down the middle. I would use this technique in order to split apart a larger volume of either incoming mud or water.
