"What could it be?" Chu Tianming couldn't help but think nervously in his heart, and then his gaze slowly moved to the inside of the treasure box, and in the psychedelic light, he vaguely saw a stone the size of a baby's fist lying quietly in the treasure box.

Now it seems that Chu Tianming can't tell which of the three types of gems in the box is, but the light does not always dissipate, and after this real psychedelic light dissipates, Chu Tianming finally saw the true face of this gem.

This is a golden gem with a whole body, the size is like a baby's fist, on the surface of the gem, there are extremely regular facets, it looks beautiful, Chu Tianming is sure that if a woman sees this gem, she will be reluctant to use it.

However, Chu Tianming was not such a person, although he was a little surprised at the first glance of this gem, but the next moment, he focused his attention on the attributes of this gem.

It's still a familiar detection technique.

Under the detection technique, the attributes of the gem in front of him suddenly appeared in Chu Tianming's mind.

'Item Name: Upgrade Stone (Treasure)

Function: A small level of artifacts that improve the level of treasures.

How to use: Place the gem on top of the object, and the blood will connect the two closely, and the gem will work. ’

The introduction was not long, it was very concise, Chu Tianming's heart moved, and he thought about how to use this treasure upgrade stone.

"It's time to upgrade the Flood Tower!" Chu Tianming smiled, "Old friend, come out!" ”

Stretching out his hand, Chu Tianming's mind moved, and the Honghuang Pagoda placed in the pole suddenly accepted his call, floated out of the pole, and emerged from Chu Tianming's palm little by little.

As Chu Tianming's early magic weapon, Honghuang Pagoda has also made a lot of contributions to him. This time, Chu Tianming got this treasure upgrade stone, the first object that came to mind. It's this Flood Tower.

In the Shangqing Immortal Mansion, there was no shortage of powerful magic weapons, but it was precisely because they were so powerful that Chu Tianming could not use them for the time being. A low-grade immortal weapon that can be used. There are only a few pieces, and they are all of the same type, Chu Tianming has the Red Refining Immortal Sword, so naturally he will not need other weapons, but in the case of magic weapons, most of them are immortal weapons above the middle grade, or they are spiritual weapons or treasure weapons below the immortal weapon.

Chu Tianming chose to upgrade the Flood Desolation Tower, firstly, because this magic weapon has been with him for some days, Chu Tianming is not a person who does not miss the old, and the Flood Desolation Tower itself is a superb treasure. Upgrading it with a Treasure Upgrade Stone is the best option.

Summons the Flood Tower. Chu Tianming immediately stretched out his hand and sucked it in, absorbing the treasure upgrade stone in the treasure box into his other hand, and then placed it on the edge of the Great Wilderness.

At this time, Chu Tianming stretched out a hand and placed it between the two, and then with a ruthless heart, he forced out a stream of blood.

The blood floated silently in the air, and under Chu Tianming's control, it floated to the middle of the Flood Desolation Tower and the Upgrade Stone, closely combining the two.

Just when Chu Tianming's blood touched the two. A magical scene happened.

Without Chu Tianming's control, the Flood Desolation Tower automatically floated. And the treasure upgrade stone was quietly floating below the Flood Tower, and then it was closely connected with blood as a medium and slowly rose upward.

After the Flood Tower and the Upgrade Stone rose to a height of several meters, they finally stopped.

At this moment, the blood between the two suddenly burst out with a dazzling blood light, and the blood light enveloped the entire underground secret room, reflecting the underground secret room a lot more hideous.

The blood light flashed, and then the Honghuang Tower was not far behind, and it also burst out with a dazzling golden light after that, followed by the treasure upgrade stone below.

The three colors of light are connected and intertwined, and in this underground secret room, they are closely integrated with each other.

…,

You have me, I have you, the three rays of light intertwined with each other, and finally condensed into a dazzling bright yellow light, the light ignored the wall above and penetrated directly.

Outside, the people who were still outside only saw a bright yellow beam of light suddenly rising into the sky in the distance, directly penetrating the defensive barrier above the base city, connecting heaven and earth together.

"What's that?"

"It seems to have come from the Lord's manor!"

"The Lord's seat has been refined to immortality again?"

……

Some people are surprised and some people are worried, every time Chu Tianming makes some big moves, Wu Xin and Chu Tianhua will always be worried, this time is the same, the two who originally listened to Chu Tianming's words and were about to go back to rest saw the beam of light rising from their son's manor, they immediately turned around and rushed towards their son's manor, nervously guessing what happened to their son.

At this time, the people who rushed to the direction of Chu Tianming Manor were not only Wu Xin and Chu Tianhua, almost as long as they could speak in the base city, the people who were allowed to enter that area rushed towards that side at the same time.

Chu Tianming in the underground secret room knew that things were going to be big as soon as he saw the bright yellow beam of light breaking through the wall at the top, and sure enough, before the beam dissipated, his powerful perception had already felt those who were rushing towards this side, and suddenly showed a wry smile.

"Your escalation is really not small!" Chu Tianming looked at the Honghuang Tower, which was still floating in the air and was upgrading, and couldn't help but smile bitterly and contact Youlan, asking her to help tell those people that she was fine.

Youlan was assigned by Chu Tianming and immediately appeared outside the gate of Chu Tianming's manor.

She is the intelligent mastermind of Mingyang Base City, not an entity, as long as she wants, she can appear in various locations in Base City at the same time, which is not difficult for her at all.

Not long after Yu Lan arrived, those who were fast had already arrived here first.

"Dark Blue! You're here too? Chu Tianhua looked at Youlan and said, "Do you know what happened to Tianming?" ”

At this time, the others also arrived here one after another, Youlan looked at these people with a smile, and without waiting for them to ask the same question again, she directly relayed Chu Tianming's words.

"The master said that you don't have to worry, he's fine, he's just busy with some things, and there may be some big movements in the future, please don't be impatient."

Youlan's words made everyone breathe a sigh of relief, but at the same time, they were also very curious in their hearts, what was this Chu Tianming busy with to make such a move, could it really be that he was cultivating some peerless divine skill?

Hearing that their son was fine, Wu Xin and Chu Tianhua breathed a sigh of relief, they were not like others who were itching to know what Chu Tianming was doing, they only cared about whether their son would be in danger, and now after hearing Youlan's words to convey Chu Tianming, they finally let go of their hearts.

"It's okay!" Chu Tianhua turned around and said, "Everyone disperse, let's not disturb Tianming here!" ”

Chu Tianhua's words were obviously very useful, as soon as he said that everyone dispersed, everyone quickly went back one after another, leaving only Chu Tianxiang and a few people to continue to chat with Youlan for a few words, and then left one after another.
