Lin Mu started running and burst into a sprint. The Wu Lim city was about ten hours' distance from the Northern town by a carriage, but Lin Mu was sure that by just going on his foot he should reach much earlier. If he were to fly using his short sword Lin Mu was sure that he would be there in less than two hours, but seeing the consumption of the spirit qi made him desist from doing that.

Lin Mu did not want to be low in spirit qi in case anything bad happened, hence he did not fly to the city. But just as he was thinking of flying, he wondered why that junior elder Fa Shiu of the Tri cauldron pennon sect hadn't flown when he was in the mid stage of the core condensation realm.

"Senior, why did that junior elder not fly away when he was escaping from me?

" Lin Mu questioned.

"It is likely that he only had a low grade spirit weapon and could not use it to fly. Not all low grade spirit weapons are able to be used to fly even if they can be used with spirit sense. Though all mid grade weapons can be used to fly.

" Xukong answered.

Lin Mu then remembered the sword that the junior elder had used and realized that the fluctuations coming off it were indeed quite less, which meant that the sword was indeed a low grade spirit weapon. He was also reminded that he now had three extra spirit swords in his ring that he got from the disciples that he killed, but did not brand them with his spirit sense as he did not want to expend his spirit sense in that.

He had already learned that there were a limited amount of spirit tools and weapons he could brand with his spirit sense, depending on the strength of his spirit sense and his cultivation. Though it also depended on the grade of the spirit tool or weapon.

Currently, Lin Mu had branded two spirit weapons, his short sword and the iron thorn spear, along with one spirit tool which was none other than the communication jade slip which also had all the records contained within it.

While Lin Mu's spirit sense had been strengthened today, he still did not want to waste it on low grade spirit swords like these. He could still use them directly without his spirit sense, anyway. The weapons he used for the thousand armament blade Scripture were all normal weapons. Even if they were of a great quality, they were no spirit weapons, thus Lin Mu realized that he could replace three of the swords in that set with the low grade spirit swords that he got.

Two hours had passed, and Lin Mu had covered around half of the distance to the city. But even now he was not feeling tired and was still running at the same pace he had started at.

'Seems like the Nameless technique of the lost immortal had more effects than I thought, but it should also be due to the conversion of my body's cells into the Xiantian physique cells.' Lin Mu thought to himself.

While running, Lin Mu was multitasking and was also practicing with his spirit sense. Now that it had grown stronger, he needed to practice with it again to get a better control over it. For that very reason, he was probing the ground, changing the shape of the spirit sense tendril into complex shapes and forms along with changing its thickness.

Though the most difficult part was splitting it into multiple parts. Whenever Lin Mu wanted to scan an area, he would create a single tendril and wave it over that area, gathering the information. But what Lin Mu wanted to do was create a constant area of perception around him by splitting his spirit sense into multiple strands.

While this would reduce the maximum range of his spirit sense, it would also make it so he knew each and everything that was happening in an area of twenty square meters around him. The range of his spirit sense fell by about five times if he split it into multiple strands.

And just as he was doing this, he also realized that there were actually quite a few hollow spaces inside the ground. In the entire distance that Lin Mu had covered till now, he realized that he had sensed no less than fifteen caves till now.

"There were caves under the Northern town as well, right? The safe House of the Hei Corps is built in a cave system. I wondered why there are so many caves here. It doesn't seem like many people know about it either.

" Lin Mu muttered to himself.

Finally, while running he heard the sound of running water and realized that he was near a river. Lin Mu came to a halt and decided to have a little drink.

"Wait, shouldn't the nameless technique of the lost immortal take care of thirst too?

" Lin Mu questioned with shock.

"Now that I think of it, it should.

" Xukong spoke.

"Then why do I still feel thirsty?

" Lin Mu asked and then realized it on his own.

"Dammit, I never drank water like I ate the meat, did it?!

" Lin Mu cursed his stupidity.

"Well, better late than never. But I'm surprised that there was no requirement for water for practicing the technique… though technically you should have also been getting quite a bit of water that is naturally present in the meat.

" Xukong added.

Lin Mu nodded his head and kneeled beside the river. The river was none other than the northern river, one of the three rivers that were the lifeline of the Wu Lim City along with the Western and Eastern river. These Rivers met in the Wu Lim city and disappeared into the ground from there only to reappear near the Southern town.

Lin Mu like a beast, dipped his head into the flowing river and started swallowing ungodly amounts of water. He would drink for a few minutes at large and then take his head out to breathe for a few seconds.

If someone were to see this scene, they would laugh, at first but then after a while, it would get horrifying seeing the amount of water that Lin Mu was drinking.
