After a long while, Su Mo found no trace of the enemy, nor did the Palace Protection Array suffer any further attacks. He then returned to the Azure Divine Palace.
"Palace Master!"
Su Mo flew before the Thick Earth Tower, and Gold One, Fire One, and the others hurried over to him.
"Stay vigilant. If the enemy appears, notify me immediately!" Su Mo ordered.
"Yes, Palace Master!" the Puppet Men answered.
Su Mo nodded, entered the Thick Earth Palace, and began cultivating once more.
Even while cultivating, Su Mo did not forget to devote a sliver of his mind to watching the Palace Protection Array outside. Should it come under attack again, he would immediately take action.
However, Su Mo had clearly worried too much. Ten days passed in a row, yet the Palace Protection Array was not attacked again.
After that, Su Mo cultivated with peace of mind and no longer paid it much attention.
After entering the Martial Emperor Realm Second Layer, the speed at which he tempered his cultivation Xuan energy dropped sharply again, because his Xuan energy was simply too vast.
Thus, another month passed. Su Mo had nearly finished tempering his cultivation Xuan energy, and he felt that he could try to break through.
"Hopefully, I can succeed!" Su Mo sighed. He then entered the Illusory Realm Divine Diagram, took out all the Spirit Stones and medicinal herbs, and began swallowing them with his eyes closed.
In an instant, his entire body was enveloped by dense spiritual energy.
Su Mo's cultivation was at the early stage of the Martial Emperor Realm Second Layer. As he swallowed the Spirit Stones, his cultivation began to rise rapidly.
Time passed. About three hours later, all the spiritual energy had been swallowed clean, and Su Mo opened his eyes.
